Intended as a tactical transport for rough, short fields when introduced in 1948, the USAF soon found that it needs were well enough met by the C-123 and helicopters so only 23 C-125s were built. Most, this one included, went directly from the factory to technical schools for use as non-flying ground trainers and were sold to a Florida trader in the mid-1950s, several finding their way on to Latin America. Pima's example was originally 48-636 becoming N2753B and then XB-GEY when sold to Triplay y Maderas de Durango SA of Mexico in 1956. It was grounded in 1960 for lack of spares.

Ex-48-636. One of two survivors, the other being in the USAF museum at Dayton, Ohio.

Delivered to the USAF in April 1951 as 48-636. To a private owner in 1955 as N2573B, then to Mexico in 1956 as XB-GEY. Back to the US in May 1968, again as N2573B. Registration cancelled in Dec 1970, and donated to the Pima museum in 1973. The c/n for this airframe (ex 48-636) is widely quoted as 2520, but C-125s 48-628 to 48-640 are c/n 2513 to 2525, not c/n 2512 to 2524 as previously thought (because c/n 2512 was not built). This means that 48-636/N2573B/XB-GEY is in fact c/n 2521.

Certainly not the most beautiful aircraft on display here.

23 C-125 Northrop Raider STOL transports were acquired by the USAF in 1948. This example as a YC-125A 30-seat troop carrier 48-636. It later served as N2573B and XB-GEY. It is one of only two surviving Raiders.

Ex 48-636. This airframe widely quoted as 2520, but that is in error. C-125 c/n 2512 was never built, which means that USAF C-125 batch 48-628 to 48-640 are c/n 2513 to 2525, not c/n 2512 to 2524 as previously thought. So 48-636/XB-GEY is in fact c/n 2521.

Ex USAF 48-636. Thirteen YC-125A's were produced for the USAF as light assault transports. An additional ten YC-125B's were produced for artic rescue duties. Deliveries began in 1950 and most were out of USAF service by 1955.

Stored in the as yet unopened Pima Museum's storage compound amongst other airframes awaiting restoration. This YC-125A is ex 48-636 and N2573B.
