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
[edit]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]
After the war, some of them (both armored and unarmored) were bought as surplus and used to carry oversize loads such as transformers, locomotives and heavy equipment.[5]
