Alexandria class heavy cruiser

[ img ]

The Alexandrias brought forth a new wave of improvements to Antaran ship design, mostly notably the return of the flush deck hull form. By then, a below deck aircraft hangar was deemed to be the best layout for cruisers as it saved on space, weight and benefitted from the structural integrity offered by the hull form. The class had notably superior seakeeping and a more stabling gun platform at poor sea states than previous classes. Armour protection increased with minimal hit to displacement. With all these improvements in mind, the navy generally regarded the Alexandrias as the best class of cruisers built up until this point, a rare sentiment particularly for treaty cruisers.

Common critique, the patterns are too perfectly applied and tidy. Otherwise an epic bunch.

Antaran nuclear guided-missile submarines

With the advent of the RGM-1 Basilisk radio-command guided missile, the Antaran Navy sought to fit to many of its vessels at possible, all in spite of huge technical problems with the weapon. Developed from the bomber launched AGM-2 and 3, the Basilisk was launched off of a rail and could be guided by a surface vessel and then handed over to an aircraft to be guided to its final trajectory 500 nautical miles away. The Basilisk used either a 1600kg warhead or a nuclear warhead. With the latter in mind, the RGM-1 was a critical piece of Antara's early nuclear deterrance capability, and thusly it was decided that submarines would be the ideal delivery vehicle as they were capable of sneaking up to enemy strongholds and ports to let loose in the event of a war.

However in the early 50s this was largely an optimistic outlook. The complicated guidance method left the launching vessels and guiding aircraft highly vulnerable to resprisal. The Basilisk developed into the RGM-2 Pegasus, with double the range and a new inertial guidance system that meant the launching vessel good shoot and then dive if needed, with the missile making its own way to the target. Successful but expensive, the guidance system and improvements to the missile were backfitted into a highly modified version of the RGM-1, resulting in the creatively named RGM-3 Basilisk II. Basilisk II and Pegasus were produced concurrently, with Pegasus stopping production just two years after entering service. Antaran missile submarines were equipped with either missile during their patrols between the 50s and late 60s before they were phased out by vastly more capable ballistic missile boats.

V-258 & V-259

[ img ]

Originally V-212 class fleet boats, both vessels were converted to carry two Basilisk missiles and used as an early test bed for the missile system. Both were active between 1355-1366 before scrapping. During the Haishang Conflict in 1364, both vessels launched conventional warheads at three inland Qing staging areas and supply depots with moderate success. Two Basilisk II missiles failed to launch and were dumped into the ocean after being safely disarmed. This was chalked up to poor training despite this occuring on both vessels.

V-303-class

Also known as the Platys class, the V-303s are a class of purpose built, diesel-electric missile submarines used in the strategic nuclear deterrance role. They were largely based on the V-287 post-war hunter-killers but constructed from the outset with hangars capable of holding RGM-1 and RGM-2 style munitions. All vessels were retired by 1371, save for V-305, which was struck by a Qing coastal defence missile in 1364 and lost with 37 sailors. V-306 fired two Pegasus missiles at a Qing port, while V-303 fired a low kiloton nuclear missile at Qingzhou's only naval base, knocking it out of action for 7 years.

Specifications

Surface displacement - 1750 tonnes
Top speed - 14 knots
Underwater speed - 12 knots
Range - 14 000nm at 10 knots
Test depth - 100 meters
Torpedoes - 6 tubes. 24 reloads.
Missiles - 2 RGM-2 Pegasus or 4 RGM-3 Basilisk II
Decoys - Noise makers

Ships in class

V-303 to V-306. 4 members.

V-311-class

[ img ]

Also known as the Wrasse class, the V-311s were based on the V-300s, the world's first nuclear submarines. Nuclear propulsion afforded the Wrasses much needed endurance and greatly improved their deterrance capability by allowing for significantly longer, safer patrols. They were active between 1358-1386. They served in the Haishang Conflict, firing conventional missiles at strategic inland targets, and on two occassions firing nuclear warheads with the goal of contaminating any potential coastal staging areas. With the introduction of SLBMs, they were retired as missile submarines and were converted to special operations transports where they saw further use in the Nuclear War just prior to their retirement. V-313 was lost during the war, presumably by ASW.

Specifications

Surface displacement - 3600 tonnes
Top speed - 15 knots
Underwater speed - 20 knots
Test depth - 200 meters
Torpedoes - 6 tubes. 24 reloads.
Missiles - 2 RGM-2 Pegasus or 5 RGM-3 Basilisk II
Decoys - Noise makers

Ships in class

V-311 to V-313. 3 members.

V-321-class

[ img ]

Based on the V-314 class of nuclear boats, the Orca/V-321 class would be the last guided missile submarines built for the navy. They had significantly improved missile capacity and underwater speed. Two of the three members of the class saw action in 1364 striking strategic targets of the coast of Qingzhou and some inland targets, particularly the powergrid and some factories. No nuclear warheads were fired by either of these two. V-322 did not participate in the war as she broke apart during her launch due to a critical construction failure.

Specifications

Surface displacement - 5100 tonnes
Top speed - 15 knots
Underwater speed - 28 knots
Test depth - 210 meters
Torpedoes - 6 tubes. 24 reloads.
Missiles - 4 RGM-2 Pegasus or 8 RGM-3 Basilisk II
Decoys - Noise makers, later mimic torpedoes

Ships in class

V-321 to V-323. 3 members.

V-300 class nuclear hunter-killer submarine

[ img ]

The V-300s, also called the Great White class, were the first two nuclear powered submarines in the world, commissioned in 1354. Both vessels were ordered side by side but differed in reactor, machinery, and sonar setup for experimentation purposes. Both members would be retired early due critical flaws inherent in both reactor designs. V-300 suffered a partial core meltdown whilst preparing to set off on patrol in 1361, an emergancy shutdown was initiated and because of fears of radiactive contanimation, most of the crew abandoned ship after a distress call was initiated. The crew was picked up and the vessel towed to a drydock. Most of the vessel interior had become irradiated and the decision was made to scuttle the vessel rather than scrap or fix it. 6 sailors and a drydock worker died to acute radiation syndrome up to three months later

V-301 suffered repeated mechanical failures that would stall the reactor throughout the 50s. While initially chalked up to human error, a flaw was identified with the reactor-machinery setup after several other submarines using a similiar setup were plagued by the same problem. After extensive overhauls of the effected ships, the issue disappeared. V-301 was scrapped in 1367 due to higher than usual wear-and-tear.

V-307 class hunter-killer submarine

[ img ]

V-307, also called the Blueback class, were the world's first class of tear-drop shaped submarines, meant to improve underwater speed, allowing the boat to be smaller, cheaper and quieter. Additional improvements came with the fusion of the control room, attack center, and conning tower, into a single space, along with other technical improvements. The V-307s were conventionally powered for the time, though they were laid down at the same time as the V-300 nuclear boats, an example of quickly shifting technology trends. A diesel-electric submarine would not be built by the navy for many years afterwards.

V-314 class nuclear hunter-killer submarine

[ img ]

V-314, also called the Seadragon class, were a class of nuclear-powered submarines (originally pure ASW ships) built alongside the V-307s. They adopted a similiar teardrop hull but differed in powerplant, machinery, bow and propellors setups. The Seadragons were the fastest submarines in the the Antaran Navy for the time, with the drawback being its propellor produced notably more noise at the same speeds as previous classes.

Surface displacement - 3075 tonnes
Top speed - 15 knots
Underwater speed - 33 knots
Test depth - 210 meters
Torpedoes - 6 tubes. 24 reloads.
Decoys - Noise makers

Ships in class

V-314 to V-320. 7 members.

V-324 class nuclear submarine

[ img ]

V-324, also called the Jack class, were a series of nuclear submarines. By now, the Antaran Navy had largely dropped the hunter-killer classification and merged surface and submarine attack missions into a single class. This resulted in cheaper boats with less emphasis on quieting and more on achieving speed. Regardless, the V-324s did still receive improvements in quieting techniques and sonar capabilities. The torpedo tubes were angled outward instead of placed directly in the bow, affording the sonar array more optimal positioning and improved detection capabilities at range.

During and after the 70s, they were given the capability of launching anti-ship missiles and SUBMIC (Submarine Mimic) decoy torpedoes through their tubes. Combined by still prolific use of nuclear torpedoes, nuclear tipped/acoustic homing weapons launched fire rocket, the Jacks were one of two workhorse classes of the period and easily the deadliest in the world. The capabilities of submarine launched nuclear torpedoes/rockets had completely changed how post-war fleet formations were organized in order to prevent catastrophic destruction by a single vessel. The world was not aware of this until ARS V-330 'Thresher' annihilated 85% of a Qing supply convoy in October 1364. Since then, naval formations called for ships to be distributed often kilometers between each other, and since nuclear proliration treaties mostly fell through, this remained common until after the 1390s. It did increase the survibility of fleets to submarine attacks.

Underwater speed - 27 knots
Test depth - 400 meters
Torpedoes - 6 tubes. 28 reloads.
