Response to catapults

 

"Hi Jim, I am a retired USN Pilot and am currently working on a presentation for the Canadian Aircrew Association on aircraft carriers. I saw your post quoting the Friedmans US Aircraft Carriers and wondered if you could see what is says for the H Mk VIII catapult. THe H Mk VIII was the replacement for the H Mk IV and should have a much greater weight capacity. Thanks, Jerry"

Friedman calls it a "H 8", and says, "This postwar high-capacity hydraulic catapult, replacing the wartime H 4B aboard modernized carriers, had a capacity of 15,000 pounds at 120 mph, or 62,500 pounds at 70 mph (61 knots). It represented the practical upper limit of hydro-pneumatic catapult design."

Although then he goes on to list the "H 9", a hydraulic catapult designed for the abortive super-carrier United States. It was to launch 100,000lb aircraft at 90 mph (78 knots) or 45,000 pounds at 120 mph (105 knots).

Hope this is of some help
