The YF23 may prove the basis for a new Japanese Stealth Fighter.
Not surprising. I always considered the -23 to be more of a bomber than a fighter. Back in the early '90s I wondered how much it would have cost to develop and build a modified version to replace the F-111.
There was some speculation on one of the Groom Lake Interceptors websites some 10-15 years ago the USAF might have been working on a stealthy replacement for the F111, and something like the YF23 might have proven ideal for it. Im not aware of any evidence however, if it ever existed it may just have been a paper project. I doubt they would be building B21 if they had something like that.
