You must be asking 'what in the world is this' is it a speedboat or is it the plane?
the answer is simple: neither its both..

This is really the australian FG-A58 atlantis 6th gen boat plane bomber But it plays the role of the a fictional russian bartini A58 in the WWIII roleplay story
besides nationality and name these planes are the same so the following disc applys to both..

This wasnt built to look pretty, i just wanted to make a jet seaplane

The plane started as a early concept in late cold war and was later remodeled into a 6th generation seaplane
the idea of the Atlantis/bartini was to carry a nuclear payload and be undetected in air or in water when it was being refueled, maintenence or doing a shore landing.
this one is currently armed with 4 bombs. max speed is ~700
