I have seen reports of up to 90mph but that seems high?
The stall speed of the F4U Corsair may be 89mph, and a safe approach speed might be 95-100mph, but that's airspeed... Measured with reference to the carrier deck, you have to substract 20mph headwind (nothing unusual at sea) and also around 30 mph of the carrier own speed. Hence, that plane touched down at a sedate 45-50 mph, with respect to the carrier deck...
It depends on the aircraft, but here's an example.
Consider the stall speed of the Grumman F6F Hellcat
Landing condition-power on - MPH 78.5
Landing condition-power off - MPH 86.0
According to this checklist, your abeam speed was 75 knots, once in landing configuration.
You'd want your approach speed to be above the stall threshold, which 75 knots is. Convert 75 knots to mph and you get 86 MPH. That's a tighter performance margin than typical approach speeds now which are typically 1.3 x stall speed. Each aircraft has its own performance margins. 90 MPH translates to about 78 knots which looks like a reasonable figure, depending on the type.
The F4U Corsair had similar performance.
Landing condition - power on - MPH 74.5
The carrier will typically try to recover with about 25-30 knots of wind down the deck, which (by turning into the wind) will be a combination of the speed of the wind that day and the ship's speed. (We nautical types use knots, not MPH).
Subtract wind over the deck from the approach speed and you get "how fast over the deck" the aircraft is traveling as it touches down.
For a very similar configuration, here is a T-28C carrier approach and landing video. The T-28C is basically an updated WW II fighter/bomber used as a trainer. (I got my initial training in a T-28B. The C's were out of use by the time I got to flight school).
