Japan has issued a request for information (RFI) to replace its Fuji-Bell AH-1 Cobra attack helicopters. The RFI, aims finding a replacement for the 71 AH-1Shelicopters fielded by the Japanese Ground Self Defence Force (JGSDF) of which 59 are reported to still be operational. Japan manufactured 89 AH-1S Cobras which were licensed by Fuji Heavy Industries.  The engine is the T53-K-703 turboshaft, which Kawasaki Heavy Industries produced under license.

The effort to replace the AH-1S is known as the AH-X Project. Boeing AH-64E Apache Guardian and the Bell AH-1Z Viper are expected to run at tender.
