==Description==
The '''Neptune''' submarine, produced by [[Galtor Naval Yards]] in [[2950]], was put into service by [[House Davion]] as a means to defend their underwater command posts from enemy attacks after they had adopted the strategy to build fixed command posts underwater to protect the vital installations from orbital or aerospace bombardment.  This also protected them from most ground units, as even [[BattleMech]]s operate at limited efficiency underwater. The Neptune proved effective in this role during the [[Fourth Succession War]], and was a common defensive unit on [[Federated Suns]] (and later [[Federated Commonwealth]]) worlds with aquatic installations. After [[Galtor]]'s conquest by [[House Kurita]] during the Fourth Succession War, the [[Draconis Combine]] began to deploy the Neptune on their worlds as well.<ref name=TRO3026>''Technical Readout: 3026'', pp. 82–83: "Neptune Submarine Profile"</ref><ref name=TRO3026R>''Technical Readout: 3026 Revised'', pp. 86–87: "Neptune Submarine Profile"</ref><ref name=TRO98>''Technical Readout: 3039'', p. 98: "Neptune Submarine"</ref>

The Neptune utilizes a double hull design, rated for a depth of up to one kilometer, with the outer hull mounting fourteen and a half tons of armor protection.  Despite its small crew, conditions on the Neptune are cramped due to the bulk and complexity of its machinery.  The Neptune's Doorman Naval [[ICE]] is a dual-mode diesel design, operating as a normal engine on the surface or able to burn a mix of diesel and hydrogen peroxide underwater. An extendable shaft carries a snorkel/periscope arrangement permitting air-breathing engine operation and visual/sensor surveillance down a depth of twelve meters.<ref name=TRO3026/><ref name=TRO3026R/><ref name=TRO98/>

==Armament==
Being a submarine, the Neptune is primarily armed with [[torpedo]] systems, navalized versions of proven missile launchers. For long range firepower, it mounts a Sea Devastator [[LRT-20]] [[Long Range Torpedo]] system with twenty tubes, though it only has enough ammunition to fire six volleys. Twin Sea Harvester [[SRT-6]] [[Short Range Torpedo]] systems provide close range firepower, again with only a single ton of ammunition between them. As a backup weapon, or for use in attacking land targets, the Neptune also mounts a single Sutel XII [[Large Laser]].<ref name=TRO3026/><ref name=TRO3026R/><ref name=TRO98/><ref>''Record Sheets: 3039'', p. 56</ref>

==Variants==
*; LRT  : Designed to counter an issue with limited reloads, the LRT variant of the Neptune replaces the Sutel XII with another Sea Devastator LRT-20 launcher and three additional tons of ammunition.<ref name=TRO98 />

*;  SRT  : Similar to the LRT variant, the SRT variant also removed the Sutel XII to make room for three additional Sea Harvesters and increased ammo for both sets of launchers.<ref name=TRO98 /> BV (2.0) = 1,075<ref>''Record Sheets: 3039'', p. 57</ref>

*;  Hunter-Killer : This version introduced in [[3024]] drops the laser and reconfigures the torpedo launchers. In the front it mounts four SRT-6s with three tons of ammunition between them and one [[LRT-15]] with two tons of ammunition. An [[LRT-5]] and an [[SRT-4]], with one ton of ammunition each, were added to the rear. The vessel's armor was reduced by two tons, although the rear armor was actually improved over the basic version. BV (2.0) = 948<ref>''Historical Turning Points: Galtor'', p. 19</ref>

*; Hyper : This experimental version combined a standard Neptune chassis with a hydrofoil system. The [[DCMS]] experimented with using the hydrofoil system as a rapid deployment system for the submarine. When it reached a combat zone, it would then retract the hydrofoil and operate as a conventional submarine. By removing the large laser, power amplifier, and a half ton of armor, designers were able to install the hydrofoil, the hydrofoil control system, an additional SRT-6 to cover the aft, and an extra ton of LRT ammunition. During the only test, the Neptune Hyper was able to operate as a submarine, but the hydrofoil system snapped off the hull and sank the craft. The hydrofoil system couldn't stand up to the pressures at depth, and the DCMS cancelled the project.<ref name=XTRO>''Experimental Technical Readout: Boondoggles'', p. 10</ref>

==Named Vessels==
* [[Bowfin (Individual Neptune-class Naval Vessel)|FSS ''Bowfin'']]
* FSS ''Ward'' - The [[Federated Suns]] Ship ''Ward'' was a Hunter-Killer variant of the Neptune which served during [[House Kurita|Kurita's]] Galtor campaign of 3025. The ship was the lead vessel of a "Wolfpack" of four other Neptune Submarines.  On May 18th, the ''Ward'' engaged Kurita 'Mechs in the water, making their way to Galtor's underwater planetary command base off the coast of New Derry. The ''Ward'' itself managed to destroy a Kurita ''[[Jenner]]''. However, the 'Mechs were decoys for incredibly fast commando submarines, later found out to be called [[Koryu]]. The ships sped past the ''Ward's'' Wolfpack and managed to deliver its payload of [[DEST]] Commandos to the Davion base.  Unfortunately, the ''Ward'' and her near-sister ships were too slow to attack them in time.  After the destruction of the Command base, the ''Ward'' and its Wolfpack were reassigned to patrol the coast of Eire for the rest of the campaign.<ref>''Historical Turning Points: Galtor'' pp. 1, 9: In the Deep (story) & Enemy Below (Scenario) - Story of the F.S.S. ''Ward'' and its actions during Galtor campaign.</ref>

==Design Quirks==
The Neptune Hyper variant is subject of the following [[Design Quirks]]:<ref name=XTRO/>
* [[Difficult to Maintain]]
* [[Illegal|Illegal (Dual  Motive  System)]]
* [[Nonfunctional|Nonfunctional  (Hydrofoil  Motive  System)]] 
* [[Obsolete|Obsolete/3032]]

==Notes==
* In German products, the unit's proper name was translated to '''Neptun'''.
