The M25 Tank Transporter (G160) was a combination 6x6 M26 armored heavy tank transporter/tank recovery tractor and companion 40-ton M15 trailer introduced into US Army service in Europe in 1944–45. Manufactured by Pacific Car & Foundry Co., it was a substantial upgrade over the Diamond T M19 transporter/trailer duo introduced in 1940.

Nicknamed the Dragon Wagon, it was replaced by the 10 ton 6x6 M123 semi-tractor beginning in 1955.[3]

Development

In 1942 a new 40 ton semi-trailer tank transporter was needed with better off-road performance than the M9 24 small-wheel trailer, and greater capacity than the 30 ton 8 large-wheel Shelvoke and Drewry semi-trailers used by the Diamond T tractor unit. Designed by the Fruehauf Trailer Company of Detroit, Michigan,[4] it was heavier than the Diamond T could manage. A companion M26 tractor was designed by the San Francisco-based Knuckey Truck Company. When it could not keep up with the Army's demands production was awarded to the Pacific Car & Foundry Co. of Seattle, Washington.

Designated TR-1 by Pacific Car, the chain-driven 12-ton 6x6 M26 tractor was powered by a Hall-Scott 440 1,090 cu in (17.9 L) 6-cylinder gasoline engine developing 240 hp (180 kW) at 2000 rpm and 810 lbf·ft (1,098 N·m) at 1200 rpm. Developed for the M26, it was used to uprate the Diamond T. Some 2,100 Type 440s were built. Baxter notes "over 1,300" M26 and M26A1 being built.[4]

Unusually, the tractor unit was fitted with both an armored cab and two winches with a combined pull of 60 tons,[4] allowing it to do light battlefield recovery work.

A later unarmored version of the M26 tractor was designated the M26A1. An experimental ballast tractor conversion was evaluated by the British Fighting Vehicle Proving Establishment[4]
