Ca.1953: TOS USAF and assigned to the 320th Bombardment Wing, Mather AFB, CA. Ca.6/59: 305th Bombardment Wing, Bunker Hill AFB, IN (Later Grissom AFB). 3/61: The right outboard engine exploded during an in-flight refueling, taking 15 feet of the wing with it. The wing was repaired. 1968: A hard landing at Bunker Hill broke the aircraft's back, permanently grounding it. It was then provided to the aircraft collection at Bunker Hill.

Many US bases have impressive gate guard parks, many of those are high quality and not inferior for official air force museums! Most probably, this B-47B is wearing false serial 20271 and is believed to be 51-2315. The latter was in a major accident prior to 1968. 52-0271 was indeed at Bunker Hill AFB (later Grissom AFB), and maybe this plane is actually the real 52-0271? The plane currently bears the markings 12135 and a sign says that the plane broke its back on a hard landing at Bunker Hill AFB, which forced its retirement, so it may well be the real 51-2315.

This B-47 was stationed at Bunker Hill AFB (now Grissom AFB) when damage from an extremely hard landing caused it to be declared a write-off and retired. Fortunately, especially as it is a rarer B-version, the frame was not scrapped and is now on display at the super Grissom Air Museum.
