The US Navy ordered six North American FJ-4 Fury's to be converted to FJ-4F's to test rocket engines, but only two were completed. These featured the North American Rocketdyne AR-1 engine, installed in a fairing above the tail pipe of the jet engine. It ran on hydrogen peroxide and JP-4 jet fuel, and provided an additional 5,000 lbf (22 kN) of thrust for short periods. The FJ-4F reached speeds of Mach 1.41 and altitude of 71,000 ft (21,600 m). The two FJ-4F aircraft were planned as high altitude interceptors and first flew in April 1957.

Both your posts Focke Wulf and Fury are fantastic as usual Mark, thank you

Never heard of this one!

Looks like the vertical stabilizer was extended and the bulbous nose might have been added to house the test equipment for the long probe. Anyone know?
