The Christie M1931, known as the Combat Car, T1 in US Cavalry use and Medium Tank, Convertible, T3 in Infantry branch, was a wheel-to-track tank designed by J. Walter Christie for the United States Army using Christie's ideas of an aero-engine and the novel Christie suspension to give high mobility.
John Walter Christie (May 6, 1865 – January 11, 1944) was an American engineer and inventor. [1] He is known best for developing the Christie suspension system used for several World War II-era tank designs, most notably the Soviet BT and T-34 [3] tanks series, and the United Kingdom Covenanter and Crusader Cruiser tanks, as well as the Comet heavy cruiser tank.
The Christie suspension is a suspension system developed by American engineer J. Walter Christie for his tank designs. It allowed considerably longer movement than conventional leaf spring systems then in common use, which allowed his tanks to have considerably greater cross-country speed.
The first machine to use this was the two-man Panzer I Ausf A influenced by the Carden Loyd tankette, and was a 5.4 ton machine with a 3.5-litre 60 hp (45 kW) petrol engine. It had 13 mm of armour and was armed with twin 7.92 mm machine guns. The more common Ausf B was a little larger to accommodate a 100 hp (75 kW) Maybach engine.
He was the goodest boy. Hurricane, the former Special Operations Canine with the Secret Service that’s considered the most decorated K-9 in US history, has died at the age of 16.
Christie revised the design and debuted the M.1921 a year later. The M.1921 had added suspension and the turret was removed and the guns placed within the hull instead, but it was also rejected on the grounds of being unreliable and under-powered. [1] Tests of the M.1921 continued until July 1924 [2] Going up and down 45º and 35º slopes.
