R4M

The R4M was a successful German aerial rocket developed during World War II. It was a 50-millimeter rocket designed for use against surface and aerial targets. Its tail fins were folded until launch, allowing for close loading arrangements on aircraft.1

During World War II, significant resources were dedicated to developing rocket-propelled weapons. Nations like Britain, Germany, the Soviet Union, Japan, and the United States all created airborne rockets. These rockets were typically fin-stabilized and launched from tube, straight-rail, or zero-length launchers under airplane wings. The U.S. also had success with a 4.5-inch rocket used against various ground targets.1
