I think the USAF operated an air/sea rescue version, not the CG.


They both did.

The B-17H was a B-17G modified for air rescue work. It had an air-droppable
lifeboat mounted between the chin and ball turrets. Over time, the armament
was dropped and some had a search radar mounted in place of the chin turret.
The designation was changed to SB-17G at some point, it remained in USAF
service until 1956.

The Coast Guard operated a similar modification of the B-17G as the PB-1G.
