Submarines

Existing Atlantean submarine classes have been preserved from the old Imperial days, but aside from improving the materials said submarines are made from, or equipping more powerful reactors or weapons, not much R&D has been implemented to create newly improved Submarines across the board for all types. The new GAOT technologies were integrated from the foundation up, wrapped around at least one of the new Gen-2 Plasma Reactors, which can provide if anything a surplus of power for all but the largest Colossal size submarines.

All submarine classes have a number of common technological features. They all have superhydrophobic coatings on the outside hulls allowing for substantially faster water movement. They are all dedicated primarily to anti-orbital and surface bombardment work via ICBM-style missiles, and they all have torpedoes and combat drones in varying quantities suitable to their size and internal volume. As well, all submarine sizes feature multiple pressure hulls, simplifying internal design while making the vessels much wider and greatly increases their survivability – even if one pressure hull is breached, the crew members in the other are safe and there is less potential for flooding.

The ICBMs should be commented on as well, being the primary anti-orbital armament they all have. They are two-stage ICBMs - one stage for underwater propulsion only, the 2nd stage a powerful plasma drive initiating once emerging from the water. One ICBM on its own has ten MIRV-style warhead drones, 5 equipped with 50-megaton plasma warheads, 3 with 10-megaton plasma warheads, and 2 with 1-megaton warheads. There are also a number of ICBMs loaded with 1 megaton or sub-megaton warhead yields, allowing for a use of varying firepower on Atlanis III’s surface that won’t disrupt the native wildlife too much while still allowing the missile’s tactical use on Orican armies or the like in an emergency.

Cruise missiles (usually equipped with kiloton-range Nanex warheads, but occasionally fission or plasma warhead for significantly higher, sub-megaton yields) have been implemented in the Large, Huge, and Colossal size submarines, capable of firing racks of 10 each at many different targets. These are the primary bombardment tool for surface groups such as Orican armies or other massive Atlantean wildlife migrations.

Additional Carrier/Transport variants were designed as well, where any combat weapons systems were stripped out and replaced with more missiles, drones, or vast hangar bays to ship large amounts of material potentially worldwide in comparative stealth from orbital sensors or the refined biological systems from the numerous sea monsters in Atlantis’ depths.

The classes are all the same (**Medium**, **Large**, **Huge, and Colossal**), with the small category having been phased out entirely due to the need for additional space to cram in vital technologies and systems. The Typhoon remains the only Colossal-type design, needing comparatively few changes due to the STC being if anything slightly more advanced than Atlantis’ current cutting edge.
