To land on a carrier, an aircraft must be strong enough to withstand sudden deceleration by the tail hook catching the arresting wire. I think it also requires strengthening the undercarriage to survive a harder "plop" on landing.
So I would like to know, how much extra weight is added due to both of these things?
I'm interested in the WW2-era piston props. The modern jet fighters are much heaver, so I'd rather save that for a later question.
Ideally, the greatest example would be a piston-prop from this era made in two versions: land and naval. Then we could just compare loaded weights. But I can't think of any. Don't think I've ever heard of that. All of the carrier-based aircraft from WW2 that I know of, were purpose built for carriers and never had a land version. Hopefully someone knows where to find airframe specs for these aircraft and has the engineering know-how to say how much steel would be unnecessary for a land version.
