The first of only three JF-105Bs ever built, prototypes for the projected RF-105B reconnaisance version that was cancelled in favour of the already existing RF-101. The trio was still completed with modified noses but without cameras. Retired in 1966, this is the only surviving one as JF-2 crashed and JF-3 was scrapped. Preserved at Lackland already in the 1970s in fake colours, later restored to this accurate test livery.
