Funryu (奮龍, Funryū) were a series of surface-to-air anti-aircraft missiles developed in Japan at the end of the Second World War. The missile's development in the late stages of the war was plagued by organizational problems and cancelled before becoming operational.
In 1945, a few samples of SAM Funryu were created and tested, but due to the surrender of the Japanese Empire, had not been finalized. All the developments on the complex were destroyed after the end of hostilities.
The first design was the Funryu 1, an air-to-surface missile (ASM) specialized for anti-shipping use. Funryu 1 was much like a miniature airplane. The warhead contained 400 kg (882 lb) of explosive and guidance was via radio control. Testing of the Funryu 1 was conducted with the missile being dropped from a modified Mitsubishi G4M bomber. However, since perfecting the methods of controlling the missile in flight would take significant time and US bombing raids against Japan were intensifying at the time, it was decided that efforts should be directed towards surface-to-air missiles (SAMs). Thus, the Funryu 1 was shelved and became the only ASM of the Funryu family.
Two more advanced versions were called the...
