On the topic of crazy Soviet war machines, this is the Tupolev TU-766 "Porpoise" also known as the Ushakov Flying Submarine. Half submarine, half light bomber/coastal patrol aircraft, this wonderful disaster was actually produced in some numbers during the Second World War.
Intended to be used for fleet defense, it proved an unwieldy and unresponsive aircraft, ill-suited to engagements of any kind. It also proved nearly impossible to find the right angle at which to enter the water, which funnily enough was the manner in which three-quarters of the production run was lost.
Oh well. Ya win some, ya lose some.
