I should have mentioned another note on this plane...
The floats are detachable and only meant for training purposes... meaning under battle conditions, these planes were launched without them... So it was a SINGLE USE plane... kind of like the modern day cruise missle. Pilots were to land on water near the Submarine carrier on return...
I also read the technology used on the submarine carrier was used to house the first generation cruise missile (Regis ?was it?)
