This is an attack craft designed for Ogel's underwater troops. Mainly a fast/overpowered weapons platform, this craft is armed with cavitating torpedoes, normal torps and flechette guns. The Manta is also capable of short duration flight, so it is used to ambush low-flying aircraft from time to time.
The Manta also has a full countermeasures packet onboard, with launching flares and chaff as needed. Manned by only a pilot, this craft was the scourge of the seas, until the Sea Monkeys made their presence known...
This was the first thing I built when I got some quarter dome parts. Since the parts were in black, it defined the rest of the craft. And since I named it the Manta, I added some manta detailing (the two projecting mandibles protecting the guns).
