Valkyr-class experimental destroyer
Sprite by helmut, kitbashed from old Blackrock ships, taken from the sprite dump thread.
Very, very fast for a destroyer, with high flux stats and a large built-in energy shotgun and underwhelming weapons otherwise, considering it has the supply costs of a cruiser. Terrible armour, well below average hull, and no shield whatsoever. On the other hand...
Features a heavily modified temporal shell -Prevents venting and shield use, and generates a decent chunk of hard flux on use and while active, but the time dilation is ten times stronger, and it can be toggled on and off at will.
Can show up rarely in Diktat, independent and pirate fleets, though the pirates have a heavily damaged version without the Geirskogul.
Herald-class frigate
Sprite by Helmut, taken from the sprite dump thread.
Statistically similar to the hyperion, it's faster but has worse flux stats, and swaps out the teleporter and medium mounts for a quantum disruptor and a quartet of built in ion burst lasers. Lacks the hyperion's absurd supply costs, though still well above the average. It's also much prettier.
Lasher (ATX)
Modified Lasher, using energy weapons. Better flux stats, higher top speed, but worse armour/hull and lower peak performance time.
Flounder
Original sprite by Medikohl, taken from the sprite dump
The flounder is relatively fast, quite well armoured and has a good, but frontal shield generator, along with an impressive amount of firepower. It's also not very maneuverable, the shield has a poor arc, and it's flux stats struggle to keep up.
Siegebreaker
More frontal firepower than an Onslaught, faster than a Conquest, and with the Paragon's fortress shield. Counterbalanced by an awful, awful turn rate, poor acceleration, the fortress shield is frontal only and has a poor arc, and only a couple of weapons can protect the sides - if attacked from the rear, only two small mounts can fire back.
