Displacing 315 tonnes, the class represented a substantial increase in internal volume, facilitating significantly improved crew habitability and logistical endurance\u2014critical factors for maintaining a distributed &#8216;lurk&#8217; posture across the Federation&#8217;s outer islands.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">While the class shared a similar engine output with its predecessors, the increased displacement resulted in a reduced maximum velocity of 33 knots. This marginal loss in speed was deemed a strategic necessity to accommodate an expanded armament suite, which included an eight-cell anti-ship missile (AShM) array and a dedicated point-defense surface-to-air missile (SAM) launcher. Notably, the torpedo tubes of the 1960s era were omitted, reflecting a 1970s naval consensus that prioritized long-range missile saturation over close-quarters kinetic strikes.

Displacing 147 tonnes, the <em>Bradan <\/em>represented a significant scaling-up of the torpedo-boat concept, utilizing a 6,200 kW triple-diesel configuration to maintain a 39-knot sprint capability despite its increased bulk.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">The class was designed as a dedicated &#8216;heavy-strike&#8217; platform, featuring four 550 mm torpedo tubes and the introduction of a twin LARA S MANPADS launcher\u2014one of the Federation&#8217;s earliest attempts at integrated organic air defense for small combatants. Ironically, the MANPADS launcher was introduced in 1970 &#8211; just a few years before the entire class would be retired, but it offered valuable insight in the challenges of mounting a MANPADS design onto a small and agile ship.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the <em>Bradan <\/em>faced persistent criticism for its &#8216;all-or-nothing&#8217; armament philosophy. Lacking a medium-caliber main gun, the vessel\u2019s surface defense relied entirely on its twin 30 mm md. 60 CIWS mounts. While effective against aircraft, these lacked the range and kinetic energy to engage enemy torpedo boats or light surface craft effectively. Some of the later versions therefore dropped one of the 30 mm CIWS mounts to mount a 40 mm md. 52 gun at the front of the ship to gain more firepower against other torpedo boats.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although the class offered vastly superior habitability and sensor range compared to the preceding generation, its strategic utility was quickly eclipsed by the advent of the anti-ship missile. By 1975, the majority of the class had been retired or reassigned to secondary roles, serving as a high-speed technological bridge to the missile era.<\/p>\n<\/details>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In Service: 1960 &#8211; 1975<\/li>\n\n\n\n<li>Displacement: 147 t standard<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 34 m\/6,72 m\/1,5 m<\/li>\n\n\n\n<li>Power: 4 x MACO 16V-SDM-343A Diesel engines with 6&#8217;200 kW combined, 39 kn, 2 shafts<\/li>\n\n\n\n<li>Range: 700 nm @ 35 kn, 2000 nm @ 13 kn<\/li>\n\n\n\n<li>Armament: \n<ul class=\"wp-block-list\">\n<li>4 x 550mm torpedo tubes<\/li>\n\n\n\n<li>1 x 30 mm\/60 md. 60 CIWS (originally 2x)<\/li>\n\n\n\n<li>1 x 40 mm md. 52 gun (originally none)<\/li>\n\n\n\n<li>1 x 2 Launcher for LBT-64<\/li>\n\n\n\n<li>removable rails for mines and depth charges<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Sensors: \n<ul class=\"wp-block-list\">\n<li>SUMA-12 Surface search\/Navigation radar<\/li>\n\n\n\n<li>RSMT-14 fire control radar, Optical Director<\/li>\n\n\n\n<li>ACNA-10 IFF<\/li>\n\n\n\n<li>CTAI-12 RWR<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Complement: 21<\/li>\n\n\n\n<li>Built: 12<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-medium\"><a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:Shershen_class_torpedo_boat_underway_1971.JPG#\/media\/File:Shershen_class_torpedo_boat_underway_1971.JPG\"><img decoding=\"async\" width=\"300\" height=\"245\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-3-300x245.jpeg\" alt=\"\" class=\"wp-image-205 lazyload\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/245;aspect-ratio:3\/2;object-fit:cover\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-3-300x245.jpeg 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-3.jpeg 508w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/a><\/figure>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">By USN &#8211; U.S. Navy photo [1] from the USS Intrepid (CVS-11) 1971 cruise book., Public Domain, https:\/\/commons.wikimedia.org\/w\/index.php?curid=21741949<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><em>Snas<\/em>-class torpedo boat<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Entering service in 1974, the <strong><em>Snas<\/em><\/strong> (dragonfly) class was the Federation\u2019s definitive solution for ultra-high-speed littoral interdiction and clandestine operations.

While originally intended for a thirty-year service life, the robust CODAD plant and modular sensor bays have allowed the class to remain in front-line service well into the 21st century.<\/p>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<ul class=\"wp-block-list\">\n<li>In Service: 1971 &#8211; 2009<\/li>\n\n\n\n<li>Displacement: 3&#8217;075 t standard<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 130 m\/13,6 m\/4,2 m<\/li>\n\n\n\n<li>Power: 4 x MACO 20V-TDM-463 Diesel engines with 30&#8217;000 kW combined, 31 kn, 2 shafts<\/li>\n\n\n\n<li>Range: 5&#8217;000 nm @ 18 kn<\/li>\n\n\n\n<li>Complement: 201<\/li>\n\n\n\n<li>Double Hangar for 2 helicopters<\/li>\n\n\n\n<li>Built: 10<\/li>\n<\/ul>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Armament<\/summary>\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Initial<\/th><th>Modernised<\/th><\/tr><\/thead><tbody><tr><td>1 x 100 mm md. 69 DP gun<\/td><td><em>1 x 100 mm md. 69 DP gun<\/em><\/td><\/tr><tr><td>2 x 30 mm md. 69 CIWS<\/td><td><em>2 x 30 mm md. 69 CIWS<\/em><\/td><\/tr><tr><td>2 x 30 mm\/60 md.60S &#8220;Seabhag 30&#8221; revolver cannons<\/td><td>2 x 30 mm\/60 md.60\/80S &#8220;Seabhag 30&#8221; revolver cannons<\/td><\/tr><tr><td>1 x octuple LBT-21 SAM launcher (+24 on magazine)<\/td><td>1 x 8-cell self-defence VLS (quad-packed LBT-21V)<\/td><\/tr><tr><td>2 x twin 400 mm torpedo launchers<\/td><td><em>2 x twin 400 mm torpedo launchers<\/em><\/td><\/tr><tr><td>1 x LFT-2 ASW launcher (+9 on magazine)<\/td><td>2 x 16-cell VLS (for LFT-4 and LBT-3M)<\/td><\/tr><tr><td>2 x quad IUT-15 SSM launchers<\/td><td>2 x quad IUT-15<strong>B<\/strong> launchers<\/td><\/tr><tr><td>removable rails for mines and depth charges<\/td><td><em>removable rails for mines and depth charges<\/em><\/td><\/tr><\/tbody><\/table><\/figure>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Sensors and Electronic Warfare<\/summary>\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Initial<\/th><th>Modernised<\/th><\/tr><\/thead><tbody><tr><td>SDCL-14B Hull Sonar<\/td><td>SDCL-35 Hull Sonar<\/td><\/tr><tr><td>SUMA-26 Navigation radar<\/td><td>SUMA-37 Navigation radar<\/td><\/tr><tr><td>SADS-24 long range Air Search radar<\/td><td>SIOM-41 Multipurpose radar<\/td><\/tr><tr><td>SADS-25 Surface\/Low Altitude radar<\/td><td>&#8211;<\/td><\/tr><tr><td>RSMT-22 Fire control system<\/td><td>RSMT-22D Fire control system<\/td><\/tr><tr><td>CTAI-22 RWR<\/td><td>CTAI-31 ESM<\/td><\/tr><tr><td>ACNA-24 IFF<\/td><td><em>ACNA-24 IFF<\/em><\/td><\/tr><tr><td>SGTF-13B VDS<\/td><td>SGTF-13C VDS<\/td><\/tr><tr><td>GTAM-25 decoy launcher<\/td><td>GTAM-39 decoy launcher<\/td><\/tr><tr><td><\/td><td>CIGA-39 ECM Suite<\/td><\/tr><tr><td>META-16 torpedo decoy<\/td><td>META-25 torpedo decoy<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/details>\n<\/div><\/div>\n\n\n\n<figure class=\"wp-block-image size-medium is-resized\"><a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:FS_Montcalm_1.jpg\"><img decoding=\"async\" width=\"300\" height=\"185\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-9-300x185.jpeg\" alt=\"\" class=\"wp-image-220 lazyload\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/185;width:300px;height:auto\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-9-300x185.jpeg 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-9.jpeg 748w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/a><\/figure>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">Attribution: Jean-Michel Roche, CC BY-SA 3.0, https:\/\/commons.wikimedia.org\/w\/index.php?curid=60923<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cruisers<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><em>Ioma-ghlac<\/em>-class Cruiser<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The <em>Ioma-ghlac<\/em>-class (Many Grasps) was commissioned in 1960 to serve as the Federation\u2019s primary long-range air defense and command platform.

The class was specifically engineered to address the increasing sophistication of anti-submarine sensors by prioritizing a drastically increased diving depth and a reduced acoustic signature. Displacing 1,500 tonnes (surfaced), it was a formidable ocean-going platform capable of long-duration interdiction missions. Its reinforced pressure hull allowed for a 280-meter diving depth, a significant strategic advantage that permitted the <em>Halabat<\/em> to utilize deep-water thermal layers to evade surface sonar.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <em>Halabat<\/em> utilized a double-hull construction with high-tensile steel alloys, a necessity for achieving the 300-meter depth rating. This depth was nearly double that of many World War II-era fleet boats, providing the Federation with a &#8220;silent&#8221; layer of defense.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To reduce sound emission, the C.L.L. engineers implemented the first generation of &#8220;Raft-Mounting&#8221; for the diesel engines\u2014isolating the vibrating machinery from the hull with rubber dampeners. While primitive compared to later 1980s designs, it made the <em>Halabat<\/em> one of the quietest submarines in the region during the 1950s.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In Service: 1953 &#8211; 1977<\/li>\n\n\n\n<li>Displacement: 1&#8217;500 t surfaced<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 77 m\/7 m\/5,1 m<\/li>\n\n\n\n<li>Power: 2 \u00d7 MACO 16V-SDM-343 diesel engines (1,300 kW each), diesel-electric propulsion, 16 kn surfaced \/ 14 kn submerged<\/li>\n\n\n\n<li>Range: 9&#8217;600 nm surfaced @ 9 kn<\/li>\n\n\n\n<li>Armament: 6x 550mm bow Torpedo Launchers, 2x 550mm stern Torpedo Launchers, 22 Torpedoes or 40 Mines<\/li>\n\n\n\n<li>Sensors: SDCL-U1 active and passive sonar (bow and flank arrays), ESM, echolot, radar<\/li>\n\n\n\n<li>Complement: 54<\/li>\n\n\n\n<li>Endurance: 45 days, 4 days submerged<\/li>\n\n\n\n<li>Diving Depth: 280 m<\/li>\n\n\n\n<li>Built: 8<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-medium\"><a href=\"https:\/\/commons.wikimedia.org\/wiki\/Category:Romeo_class_submarines#\/media\/File:Romeo_clsss_submarine.JPG\"><img decoding=\"async\" width=\"300\" height=\"240\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-13-300x240.jpeg\" alt=\"\" class=\"wp-image-239 lazyload\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/240;aspect-ratio:3\/2;object-fit:cover\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-13-300x240.jpeg 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-13.jpeg 600w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/a><\/figure>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">Public Domain, https:\/\/commons.wikimedia.org\/w\/index.php?curid=2352127<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><em>Silis<\/em>-class Submarine<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Introduced in 1969, the <em>Silis<\/em>-class (catfish) was the Federation\u2019s first &#8220;True Submarine.&#8221; Departing from the sharp, ship-like bows of previous eras, the class utilized a rounded, hydrodynamic &#8220;whale-shaped&#8221; hull to minimize drag and acoustic turbulence. To further reduce its signature, the C.L.L. pioneered the use of an external anechoic rubber coating, designed to absorb active sonar pulses from enemy escorts. With a significantly expanded battery bank and a streamlined sail, the <em>Silis<\/em> could sustain 18 knots submerged. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <em>Silis<\/em> abandoned the twin-screw layout of its predecessors for a single, large-diameter propeller on the centerline. This configuration, combined with the teardrop hull, drastically reduced the cavitation threshold, allowing the submarine to move faster before being detected. The &#8220;teardrop&#8221; geometry also improved stability during high-speed underwater maneuvers. The application of rubber tiling across the hull was a major technological hurdle for the C.L.L. shipyards. This coating served a dual purpose: it dampened the internal noise of the 73-man crew and machinery, and it significantly reduced the &#8220;Return Echo&#8221; of enemy active sonar, making the <em>Silis<\/em> a &#8220;ghost&#8221; in the archipelago&#8217;s complex acoustic environment. To support the 18-knot submerged dash, the internal volume was dominated by massive lead-acid battery compartments. This allowed the <em>Silis<\/em> to remain fully submerged for 8 days\u2014double the endurance of the <em>Halabat<\/em>\u2014making it an ideal platform for long-range ambushes in the North Reach.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In Service: 1969 &#8211; 1992<\/li>\n\n\n\n<li>Displacement: 1&#8217;900 t standard surfaced<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 72,7 m\/9,9 m\/7,4 m<\/li>\n\n\n\n<li>Power: 2 \u00d7 MACO 16V-SDM-343A diesel engines (1,550 kW each), diesel-electric propulsion, 12 kn surfaced \/ 20 kn submerged<\/li>\n\n\n\n<li>Range: 6&#8217;000 nm @ 12 kn<\/li>\n\n\n\n<li>Armament: 6x 550mm bow Torpedo Launchers, 22 Torpedoes or 28 Mines<\/li>\n\n\n\n<li>Sensors: SDCL-U3 active sonar\/passive sonar (bow &amp; flank arrays), CTAI-22 ESM, echolot, radar<\/li>\n\n\n\n<li>Complement: 71<\/li>\n\n\n\n<li>Endurance: 45 days, 8 days submerged (snorkel)<\/li>\n\n\n\n<li>Diving depth: 300 m<\/li>\n\n\n\n<li>Built: 6<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-medium\"><a href=\"https:\/\/upload.wikimedia.org\/wikipedia\/commons\/6\/6f\/JS_Uzushio_%28SS-566%29.jpg\"><img decoding=\"async\" width=\"300\" height=\"175\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-14-300x175.jpeg\" alt=\"\" class=\"wp-image-242 lazyload\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-14-300x175.jpeg 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-14.jpeg 500w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/175;\" \/><\/a><\/figure>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">By \u9632\u885b\u7701\u30fb\u81ea\u885b\u968a\u30db\u30fc\u30e0\u30da\u30fc\u30b8, CC BY 4.0, https:\/\/commons.wikimedia.org\/w\/index.php?curid=32561683<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><em>Tarr-geal<\/em>-class Submarine<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Commissioned in 1980, the <em><em>Tarr-geal<\/em><\/em> (White Belly &#8211; a traditional name for deep-dwelling fish) served as the Federation\u2019s premier patrol submarine for three decades. Unlike the long, lean hulls of the 1950s, the <em><em>Tarr-geal<\/em><\/em> utilised a high-beam, &#8220;fat&#8221; teardrop geometry that prioritized internal volume for advanced computer processing and high-capacity battery banks. This class moved the Federation into the era of the &#8220;Submerged Missile Platform,&#8221; introducing the ability to launch both anti-ship and land-attack cruise missiles while remaining at depth. With a vastly improved acoustic signature and a 20-knot submerged sprint, it was designed to &#8220;lurk&#8221; in the deep trenches of the North Reach, acting as a hidden deterrent against both surface fleets and coastal infrastructure.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">With a length-to-beam ratio of nearly 7.7:1, the <em><em><em>Tarr-geal<\/em><\/em><\/em> is significantly broader than its predecessors. This &#8220;whale-like&#8221; shape (inspired by the late-Cold War shift toward shorter, fatter hulls) provides exceptional maneuverability and allows for a massive internal battery deck located beneath the crew quarters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Reduced Emissions requirement led the C.L.L. engineers to develop the &#8220;Silent Snorkel&#8221; system\u2014utilizing advanced exhaust scrubbers and underwater diffusers to break up the heat signature and bubbles of the diesel engines. Internally, every piece of machinery\u2014down to the kitchen galleys\u2014was mounted on a &#8220;Double-Resilient&#8221; floating cradle to prevent vibration from reaching the outer hull.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To achieve 20 knots silently, the <em><em><em><em>Tarr-geal<\/em><\/em><\/em><\/em> utilized a highly skewed, seven-bladed &#8220;scimitar&#8221; propeller. This design prevents the formation of vacuum bubbles (cavitation) at high speeds, allowing the submarine to sprint between patrol sectors without &#8220;ringing the bell&#8221; for enemy sonobuoys.<\/p>\n<\/details>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In Service: 1980 &#8211; 2010<\/li>\n\n\n\n<li>Displacement: 2&#8217;100 t surfaced<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 76,0 m\/9,9 m\/7,4 m<\/li>\n\n\n\n<li>Power: 2 \u00d7 MACO 16V-TDM-453G diesel engines (2,000 kW each), diesel-electric propulsion, speed of 12 knots surfaced and 20 knots submerged<\/li>\n\n\n\n<li>Range: with snorkel 8&#8217;000 nm @ 7 kn, submerged 500 nm @ 3 kn<\/li>\n\n\n\n<li>Armament: 6x 550mm bow Torpedo Launchers, 18 Torpedoes, 24 Mines, land attack cruise missiles, anti-ship missiles<\/li>\n\n\n\n<li>Sensors: SDCL-U3 bow sonar (active\/passive), SDFL-U3 flank arrays, CTAI-31 ESM, echolot, radar<\/li>\n\n\n\n<li>Complement: 72<\/li>\n\n\n\n<li>Diving depth: 300 m<\/li>\n\n\n\n<li>Built: 6<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-medium\"><a href=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-15.jpeg\"><img decoding=\"async\" width=\"300\" height=\"240\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-15-300x240.jpeg\" alt=\"\" class=\"wp-image-243 lazyload\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/240;aspect-ratio:16\/9;object-fit:cover\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-15-300x240.jpeg 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-15-768x614.jpeg 768w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-15.jpeg 960w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/a><\/figure>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">PH2 Carmen Yebba, U.S. Navy, Public domain, via Wikimedia Commons<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Mine countermeasure ships<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><em>Cr\u00f9ban-Creige<\/em>-class minesweeper<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The <em>Cr\u00f9ban-Creige<\/em>-class (Rock Crab) was a series of wooden-hulled coastal minesweepers (MSC) and minelayers commissioned between 1955 and 1975 to provide littoral defense and mine countermeasures within the complex geography of a tropical archipelago. Designed after the Third Cataclysm, the class was a response to the proliferation of sophisticated naval mines that utilized magnetic and acoustic influence sensors. To counter these threats, the vessels utilized advanced non-ferrous construction techniques. <\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">The hallmark of the <em>Cr\u00f9ban-Creige<\/em> design was its composite multi-layered wooden hull, an engineering necessity to achieve a low magnetic signature. The hull was constructed using a double-diagonal planking method, utilizing high-density teak and mahogany over a structural skeleton of aluminum alloy frames. This specific choice of timber was dictated by the operational environment; the hardwoods offered natural resistance to the humid climate and the localized threat of <em>Teredo navalis<\/em> (shipworms), which frequently compromised softer woods in tropical waters. At a standard displacement of 280 tonnes and a length of 47 meters, the vessels maintained an exceptionally shallow draft of 2.2 meters. This allowed the class to &#8220;scuttle&#8221; into shallow lagoons and over coral sandbars, effectively hiding from larger surface threats while maintaining a vantage point for minelaying or sweeping operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The class was equipped with a versatile suite of weaponry and sensors to fulfill its dual role as both a &#8220;sweeper&#8221; and a &#8220;layer.&#8221; Primary air defense and surface engagement were provided by a single 40 mm md. 52 anti-aircraft gun mounted on the forecastle, a reliable and manually operated system capable of detonating surfaced mines or deterring light aircraft. For its primary mission, the aft deck was fitted with mechanical &#8220;Oropesa&#8221; cutting sweeps for moored mines and modular rails for the deployment of contact mines. Sub-surface detection relied on a high-frequency, hull-mounted sonar optimized for identifying &#8220;mine-like objects&#8221; on the seabed. Defensively, the class was fitted with a Radar Warning Receiver (RWR), a critical piece of electronic warfare kit for the era that provided the crew with early warning of enemy radar &#8220;painting&#8221; the ship, allowing the wooden vessel to leverage its low profile and retreat into the radar clutter of the archipelago\u2019s mountainous islands.<\/p>\n<\/details>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In Service: 1955 &#8211; 1975<\/li>\n\n\n\n<li>Displacement: 280 t standard<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 47,1 m\/7,2 m\/2,2 m<\/li>\n\n\n\n<li>Power: 2 \u00d7 MACO 12V-SDM-333 diesel engines (950 kW each), 1,900 kW combined, 23 kn<\/li>\n\n\n\n<li>Range: 1&#8217;250 nm @ 15 kn<\/li>\n\n\n\n<li>Armament: 1 x 40 mm md. 52 AA gun, Mines, DCs<\/li>\n\n\n\n<li>Sensors: SCDL-14W Sonar, SUMA-11 Surface\/Navigation Search radar<\/li>\n\n\n\n<li>Electronic Warfare: CTAI-12 RWR, ACNA-10 IFF<\/li>\n\n\n\n<li>Complement: 31<\/li>\n\n\n\n<li>Built: 16<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-medium\"><a href=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-19.jpeg\"><img decoding=\"async\" width=\"300\" height=\"176\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-19-300x176.jpeg\" alt=\"\" class=\"wp-image-255 lazyload\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-19-300x176.jpeg 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-19.jpeg 765w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/176;\" \/><\/a><\/figure>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">Von Ullischnulli (Ulrich Stelzner) &#8211; Eigenes Werk, CC BY-SA 3.0, https:\/\/commons.wikimedia.org\/w\/index.php?curid=287212<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><em>An Gath-Dubh<\/em>-class minesweeper<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>An Gath-Dubh-class<\/strong> (Stingray) represented a significant technological leap in littoral warfare for the archipelago, succeeding the <em>Cr\u00f9ban-Creige<\/em> as the primary defensive asset for shallow-water operations. Entering service in 1970, the class was designed to meet the evolving threats of the late Cold War, where high-speed missile boats and advanced influence mines necessitated a more agile and technologically dense platform. While smaller in displacement than its predecessor at 200 tonnes, the <em>Sian-Mhara<\/em> integrated automated fire control and a vastly improved endurance profile, allowing the fleet to maintain a persistent presence across the outermost reaches of the archipelago. The class remained the frontline standard for coastal sovereignty until the mid-1990s, when they were eventually phased out in favor of multi-role corvette designs.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">In a departure from traditional timber construction, the <em>Sian-Mhara<\/em>-class was among the early adopters of Glass-Reinforced Plastic (GRP) for its primary hull structure. By the late 1960s, GRP had become a viable material for naval architecture, offering a completely non-magnetic signature and superior resistance to the corrosion and osmotic blistering typical of tropical environments. The monolithic GRP hull provided an exceptional strength-to-weight ratio, allowing for a broader 7.7-meter beam on a relatively short 40.5-meter frame. This design choice resulted in a highly stable platform with an ultra-shallow draft of only 1.6 meters, specifically engineered to navigate over sensitive coral reefs and through silted estuarine waters that would be impassable to contemporary steel or even wooden vessels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The propulsion system of the <em>Sian-Mhara<\/em> was remarkably powerful for its size, featuring two high-output diesel engines delivering a combined 3,100 kW. This enabled a top speed of 24 knots, providing the necessary &#8220;sprint&#8221; capability for rapid response to territorial incursions. More notable, however, was the class\u2019s strategic endurance; by optimizing the hull form for fuel efficiency at lower speeds, the vessels achieved a range of 2,400 nautical miles at 10 knots.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The class was defined by its integration of early-generation digital combat systems, specifically designed to counter the threat of anti-ship missiles and low-flying aircraft. The primary armament consisted of a 30 mm md. 60 Close-In Weapon System (CIWS), which was linked to a dedicated Fire Control System (FCS) and radar suite. This automated capability provided a layer of point defense that was previously unavailable to coastal sweepers, allowing the <em>Sian-Mhara<\/em> to survive in higher-threat environments. For its mine-warfare role, the ship retained aft-mounted rails for both mine-laying and depth charge deployment, supported by a modernized sonar suite capable of high-resolution seafloor mapping, as well as acoustic and magnetic sweep gear.<\/p>\n<\/details>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In Service: 1970 &#8211; 1995<\/li>\n\n\n\n<li>Displacement: 200 t standard<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 40,5 m\/7,7 m\/1,6 m<\/li>\n\n\n\n<li>Power: 2 x MACO 16V-SDM-343A Diesel engines (1&#8217;550 kW each), 3&#8217;100 kW combined, 24 kn<\/li>\n\n\n\n<li>Range: 2400 nm @ 10 kn<\/li>\n\n\n\n<li>Armament: 1 x 30 mm\/60 md. 60 CIWS, Rails for Mines and Depth Charges<\/li>\n\n\n\n<li>Sensors: SDCL-13F Sonar, DRVN-32 Surface\/Navigation Search radar, DRBC-33 FCS for CIWS<\/li>\n\n\n\n<li>Electronic Warfare: CTAI-22 ESM, ACNA-24 IFF<\/li>\n\n\n\n<li>Complement: 27<\/li>\n\n\n\n<li>Built: 12<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-medium\"><a href=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/oktopus.png\"><img decoding=\"async\" width=\"300\" height=\"209\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/oktopus-300x209.png\" alt=\"\" class=\"wp-image-254 lazyload\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/oktopus-300x209.png 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/oktopus.png 718w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/209;\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Auxiliary Ships<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><em>An t-\u00c0iteach<\/em>-class Fleet Replenishment Tanker (AO)<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>An t-\u00c0iteach-class<\/strong> (<em>Replenishment<\/em>) was the cornerstone of the archipelago\u2019s post-war naval expansion, commissioned in 1952 to provide the logistical &#8220;bridge&#8221; between shore-based depots and the frontline fleet. Unlike the small, coastal tankers of the pre-war era, the <em>An t-\u00c0iteach<\/em> was designed to supply and shuttle fuel to task forces and Tankers. This required the vessel to maintain pace with high-speed surface combatants, including the navy&#8217;s surviving heavy units\u2014its Third-Cataclysm-era aircraft carriers and battlecruisers\u2014who demanded constant resupply to maintain a presence in the outer archipelago.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">To meet the requirements of a diverse fleet, the <em>An t-\u00c0iteach<\/em>-class featured a high-volume, subdivided hull of welded steel construction. Measuring 115 meters in length with a deep 7.2-meter draft, the ships were significantly larger than contemporary coastal auxiliaries. Because they were tasked with fueling 6,000-tonne destroyers and capital ships in open sea states, the class was equipped with advanced active stabilization systems to minimize roll during replenishment operations.

Construction took place at the Ce\u00f2lraidh shipyard, with lead ship&nbsp;<em>Sg\u00f9rr M\u00f2r<\/em>&nbsp;(LPD-1, &#8220;The Great Peak&#8221;) commissioning in 1974 and final unit&nbsp;<em>Sg\u00f9rr Dearg<\/em>&nbsp;(LPD-4, &#8220;The Red Peak&#8221;) in 1978.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">The Sg\u00f9rr-class features a through-deck design with a stern well deck for LCU\/LCVP operations and a spacious vehicle deck for 30 APCs (approximately 800 tonnes cargo). The 7.0 m draft supports operations in moderate-depth approaches, while the 24 m beam provides stability for aviation. CODAD propulsion delivers efficient long-range transit, with all four engines online for 23 knots maximum.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Armament prioritizes point defense, with the LBT-21 octuple launcher (24 missiles ready) providing medium-range air cover and the three 30 mm CIWS handling terminal threats. The SIOM-45 radar supports air\/surface search to 150 nm, integrated with RSMT-22 for precise fire control. Aviation facilities enable sustained VERTREP and airmobile assault, with capacity for medium-lift helicopters.<\/p>\n<\/details>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Service: 1974 \u2013 2015<\/li>\n\n\n\n<li>Displacement: 12,000 t standard<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 158 m\/26 m\/6,2 m<\/li>\n\n\n\n<li>Power: 4 \u00d7 MACO 16V-TDM-472 (8,800 kW each), 24 kn, 4 shafts<\/li>\n\n\n\n<li>Range: 8&#8217;500 nm @ 18 kn<\/li>\n\n\n\n<li>Complement: 340 + 600 marines<\/li>\n\n\n\n<li>Armament: 3 x 30 mm\/55 md. 69 CIWS, 1 x octuple LBT-21 SAM launcher (+20 on magazine), 2 x 40 twin mm md. 78<\/li>\n\n\n\n<li>Sensors: SIOM-45 multi purpose radar, SUMA-26 Surface\/Navigation radar, RSMT-22B Fire control system, CTAI-31 ESM, CIGA-39 EW Suite, ACNA-24 IFF, GTAM-39 decoy launcher, Meta-25 torpedo decoys<\/li>\n\n\n\n<li>Capacity: 2 LCAC + 4 LCVP + 30 APCs<\/li>\n\n\n\n<li>Aviation: Hangar for 12 Medium Lift Helicopters + deck for 8 \u00d7 Medium Lift Helicopters<\/li>\n\n\n\n<li>Built: 4 ships: Sg\u00f9rr M\u00f2r: The Great Peak, Sg\u00f9rr Dubh: The Black Peak, Sg\u00f9rr Fiadh: The Wild Peak, Sg\u00f9rr Dearg: The Red Peak<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-medium is-resized\"><img decoding=\"async\" width=\"300\" height=\"200\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-29-300x200.jpeg\" alt=\"\" class=\"wp-image-316 lazyload\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/200;width:330px;height:auto\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-29-300x200.jpeg 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-29.jpeg 330w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/figure>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">Photo: LA(Phot) Bernie Henesy\/MOD, OGL v1.0OGL v1.0, via Wikimedia Commons<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Fr\u00e0och-class <strong>Landing Ship Tank (LST)<\/strong><\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The&nbsp;<strong>Fr\u00e0och-class<\/strong>&nbsp;(heather) was a class of twelve landing ship tanks (LSTs) operated by the Federation Navy from 1976 to 2005. Designed as a replacement for World War II-era amphibious vessels, the Fr\u00e0och-class emphasized beaching operations, light infantry transport, and self-defense in regional archipelago scenarios. Construction occurred at three domestic yards, with the lead ship&nbsp;<em>Fr\u00e0och<\/em>&nbsp;(LST-1) commissioning in 1976 and final unit&nbsp;<em>Uig<\/em>&nbsp;(LST-12) in 1982.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">The Fr\u00e0och-class hull featured a bow door and ramp for direct beaching, with a 2.0 m draft enabling operations over coral reefs and shallow approaches. The well deck accommodated two LCMs and two LCVPs, while the tank deck held 12 APCs or equivalent cargo (approximately 500 tonnes). CODAD propulsion provided efficient cruising, with diesels alone for 4,500 nm range.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Armament centered on a single 100 mm dual-purpose gun for surface and limited anti-air fire, augmented by twin 30 mm CIWS mounts and 40-barrel 120 mm rocket launchers for saturation defense against missile and air threats. Sensors included the SIOM-45 for air\/surface search, with RSMT-22 providing gun\/launcher fire control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">All twelve ships entered service between 1976 and 1982, participating in archipelago patrols, humanitarian operations, and Marine battalion deployments. Decommissioning began in 1995, with the class fully retired by 2005 in favor of newer amphibious platforms.<\/p>\n<\/details>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Service: 1976 \u2013 2005<\/li>\n\n\n\n<li>Displacement: 3,000 t standard<\/li>\n\n\n\n<li>Length\/Beam\/Draft: 91 m\/15,1 m\/2 m<\/li>\n\n\n\n<li>Power: 2 \u00d7 MACO 12V-TDM-462 (6,600 kW each), CODAD, 21 kn, 2 shafts<\/li>\n\n\n\n<li>Range: 6&#8217;500 nm @ 14 kn<\/li>\n\n\n\n<li>Complement: 85 + 300 marines<\/li>\n\n\n\n<li>Armament: 1 x 100 mm md. 69 DP gun, 2 x 30 mm\/55 md. 69 CIWS, 2 x 40-barrel 120 mm rocket launcher, 2 x 40 twin mm md. 78<\/li>\n\n\n\n<li>Sensors: SIOM-45 multi purpose radar, SUMA-26 Surface\/Navigation radar, RSMT-22 Fire control system, CTAI-32 ESM, ACNA-24 IFF, GTAM-39 decoy launcher<\/li>\n\n\n\n<li>Capacity: 2 LCM + 2 LCVP + 12 APCs<\/li>\n\n\n\n<li>Aviation: Landing Pad<\/li>\n\n\n\n<li>Built: 12 ships<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-medium\"><img decoding=\"async\" width=\"300\" height=\"208\" data-src=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-24-300x208.jpeg\" alt=\"\" class=\"wp-image-308 lazyload\" data-srcset=\"https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-24-300x208.jpeg 300w, https:\/\/laywenrania.uk\/blog\/wp-content\/uploads\/2026\/04\/image-24.jpeg 330w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/208;\" \/><\/figure>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">JMSDF, CC0, via Wikimedia Commons<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Sruth-class<strong>&nbsp;LSL (Landing Ship Logistic)<\/strong><\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The&nbsp;<strong>Sruth-class<\/strong>&nbsp;(<em>Current<\/em>) was a class of four landing ship logistics (LSLs) operated by the Federation Navy from 1978 on.

Construction occurred at two domestic commercial yards, with lead ship&nbsp;<em>Sruth-luath<\/em>&nbsp;(LSL-1) commissioning in 1978 and final unit&nbsp;<em>Sruth-domhain<\/em>&nbsp;(LSL-4) in 1982.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Description<\/summary>\n<p class=\"wp-block-paragraph\">The Sruth-class featured a ro-ro design with bow and stern ramps enabling rapid vehicle discharge onto unprepared beaches or piers. The 4.0 m beaching draft supported coral reef operations, while the 6.0 m deep load draft permitted UNREP alongside Saorsa AORs. Cargo capacity emphasized wheeled\/tracked logistics vehicles over heavy armor, complementing Fr\u00e0och LSTs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CODAD propulsion balanced speed with endurance, maintaining station with 18-knot task groups. Self-defense mirrored contemporary combatants, with the 100 mm gun providing surface fire support and LAR-21 SAMs covering replenishment evolutions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The four ships supported amphibious task forces through the 1980s-1990s, participating in island-hopping exercises and humanitarian surges.
