These are the ships currently in the ship library:

Squid Corvette Mk2b A version of the Squid corvette which only uses EMP cannons.
Squid Corvette Mk3
Squid Corvette Mk3a
Squid Corvette Mk3b
Beetle Destroyer Mk1 A retrofit of a retrofit of the 4th version of a retrofitted biter. Large Shields don't cover the rear.
Beetle Destroyer Mk2
Beetle Destroyer Mk3
Hunter Fighter Mk1 (replaced by sniper fighter) A modified Ion frigate, it lacks shields & point defense and isn't that well designed so it was replaced by the Sniper fighter.
Sniper Fighter Mk1 (replaced hunter fighter) A replacement for the Hunter fighter, the Sniper fighter fixes the issue of having no shields or point defense while keeping the same firepower at slightly less cost.
Leaf Heavy Cruiser Mk1 A mash of the engins from the Biter, sides from the Beetle and (you can't really see it) the body from the Archangel, this ship is basically an upsized Bettle.
Leaf Heavy Cruiser Mk2
Leaf Heavy Cruiser Mk3 (replaced by leviathan battleship)
Hammer Missile Frigate Mk1 A modified Biter, it has an underwhelming amount of firepower for it's size.
Hammer Missile Frigate Mk2
Pole Frigate Mk1 Basically a Squid corvette, but extended beyond the point of being maneuverable.
Pole Frigate Mk2
Spear Frigate Mk1 A good, all purpose ship. The Spear frigate is the most used ship.
Spear Frigate Mk2
Leviathan Battleship Mk1 (replaced leaf heavy cruiser) (won't spawn in bounty mode due to strength) An extremely powerful ship, the Leviathan is almost unkillable to the point of being able to take down dreadnoughts with superficial damage or even without a scratch.
Prototype Leviathan Carrier (won't spawn in bounty mode due to strength) A modified Leviathon battleship, this trades its cannons for missiles, a railgun, heavier armor, 8 Mk3 Arrow head fighters and 2 Mk3 Squid corvettes.
The only rules for submitting ships are that they cant use mods other than Parts Galore and that they can't use the large strong bubble shields (too OP for bounty mode). Also Cosmoteer doesn't allow ships that cost more than 25,000,000 to spawn in bounty mode.
