This is a collection of Spartan warships. I'll add to it gradually. Design principles:
1) Spartans use amor rather than shields
2) Spartans prefer ballistic weapons to energy weapons
3) Spartan design emphasises raw power
4) Spartan ships are... spartan inside. Spartans don't suffer the LUX penalty.
The Spartans are not known for their subtlety, and this is nowhere more apparent than in the design of their warships. The Kor-Lang class is designed to intimidate and destroy. The enormous magnetic railgun at the front of the ship can decimate most foes with ease, and the broadsides particle cannons can rain a constant stream of fire down upon the Kor-Lang’s enemies. Like most Spartan ships, the design is frugal at best - Spartans operate better without luxury, and so none of the vessel’s tonnage is wasted on anything other than training halls, an armory, and capacity for 100 aggressive Spartan berserker troops.
This behemoth is more an array of giant projectile cannons attached to an engine than anything else. The six enormous cannons point forwards, and are able to unleash a salvo capable of immense destruction. The vessel lacks little else in armaments, other than point-defence systems, and is often accompanied by smaller warships. If a Kra'Changa arrives in your system, something's getting destroyed.
One of the earliest Spartan carriers, the Ka'Jor class is able to deploy a complement of 100 fighters, along with 20 support vessels filled with up to 400 berserkers armed and ready to board enemy ships. Although a monster, the Ka'Jor can be vulnerable on its own due to a lack of overlapping fire-arcs (a theme common amongst Spartans, who like to concentrate firepower forwards).
This iconic, feared Spartan ship is well-known. Designed for ambushes, it is adept at sudden, deadly attacks. The wing-mounted railguns are powerful, short range guns which can shred an enemy in seconds. The ubiquitous ship is old, but still sees plenty of service today - many pirates use older models, although few of those still retain the Spartan components, having long since been replaced piecemeal (thus the example shown in the NEW core rulebook). The ship's main weakness, at least as originally designed, is the complete lack of defensive measures - the Spartans used it for quick, lethal attacks, and never saw the need for armor or point-defences.
This fighting vessel is a mainstay of the Spartan navy, often deployed in groups to protect larger warships. Three forward-pointing railguns and - unusually for Spartan vessels - one of their only deflector shield models give it a nasty bite. A crew of four mans the T'loth, sharing a tiny dormitory and a one-man medical closet.
