In 1949 my dad was deployed to Port Leyaute, Morocco, to help develope radar bombing techniques for the Navy's first nuclear bomber, the North America AJ2 Savage. This was a 3 engined bomber about the size of a P2V Neptune patrol plane, and had 2 Pratt & Whitney radial engines and a turbojet engine buried in the rear fuselage. The former tail gunner's position was the jet exhaust outlet. The bombs, or "shapes" dropped were cement filled Fat Man bomb casings weighing in at 10,000 pounds.
I don't know why the bombing range was in Morocco instead of the desert southwest, but they dropped dummy Fat Man bombs there for years. He had to deploy there again in 1951 or 1952 for the same purpose.
