Corinthian Empire (ally to the Imperium) engineers spent years trying to perfect a mass-produce fighter capable of water, air and space fighting. Their efforts finally paid off and the Psari was born. Armed with six particle beam cannons, all of which can fire through water, air and space, making the Psari a force to be reckoned with. The tails are used for flippers/rudders when in water. The tails are rudders when in air as well. So in summation the Psari is a devestating arsenal to the Corinthian army.
