NASA's WB-57F, in this case NASA 928, on short final to runway 32 at March ARB. It's previous military serial was 63-13298

Originally built as B-57B 52-1583. Rebuilt as RB-57F 63-13293 with extended wings, more powerful engines etc. Wears a NASA fin band during preservation at Warner Robins.

What a wingspan! This is former USAF WB-57F 63-13501, which in turn was remanufactured by General Dynamics from RB-57D 53-3975. It was transferred to MASDC storage on 15 Sep 1982 and is now on display at the Pima museum.

Ex USAF 63-13503, which is a rebuild of RB-57D 53-3974.

This old B-57 was built as RB-57A 52-1433 but acquired the new serial upon conversion by General Dynamics. It served previously with the 58th Weather Squadron at Kirklnad AFB, NM before being retired to MASDC during June 1974 where it was stored with the Inventory No. BM109. Still surviving 40 years later!!

Originally with the USAF as 63-13501 (rebuilt by General Dynamics from RB-57D 53-3975), this aircraft was transferred to NASA as 925. She arrived at AMARG during Sep 1982 and migrated across the road to the Pima Air & Space Museum where she was photographed in the restoration compound.

This was B-57B 53-3918, rebuild as WB-57F 63-13295 by General Dynamics. As such it served with the 58th Weather Squadron based at Kirtland AFB, NM before arriving at AMARC as BM074 on 26 July 1972. It was retrieved from storage in May 2011 and rebuilt to flying condition using from parts from 63-13290 and 63-13293. In July 2013 it was delivered to the NASA as WB-57F N927NA.

Built as B-57B 53-3918. Extensively modified by General Dynamics with higher power engines, extra wingspan etc as RB-57F 63-13295. Later redesignated WB-57F. To AMARC on 26 July 1972, but retrieved from storage in May 2011 and rebuilt to flying condition using from parts from 63-13290 and 63-13293.
