YaG-10K 76mm Kurchevsky RCL
YaG-10 chassis with 76mm recoilless gun "K" of L.V. Kurchevsky-type was developed in 1933 for reconnaissance units of infantry and cavalry. The 76mm recoilless gun used 6.23kg shells (341 m/s), but because of the insufficient efficiency of Kurchevsky`s recoilless guns all further development was stopped in the end of 1934. A total of 23 copies of the similar Soviet SPG SU-76K with 76mm recoilless gun were mounted on the GAZ-TK chassis and an unknown but much smaller number on the YaG-10 chassis, 1933-1934. This small batch of vehicles apparently did not warrant a unique designator, and the "YaG-10K" nomenclature is purely notional.
The 8-ton YaG-10, built at the Yaroslavl state motor vehicle plant (»YaG« or »YaGAZ«) from 1931 on, was for long the heaviest truck of the Soviet Union. At the end of 1931, a huge sample of a three-axle I-X-NATI truck was built at Yaroslavl State Automobile Plant (YAGAZ). And in early February 1932, the serial production of this truck under the brand YaG-10 was mastered. It had a lifting capacity of 8,000 kg, a curb weight of 6,800 kg, and could overcome lifting with a full load up to 20 degrees. At the highest speed of 42 km / h, it had an operational fuel consumption of 55 liters per 100 km of track. The spring suspension of the rear axles of the YaG-10 was of the WD type. To increase the cross-country, removable track chains of the Overall type were provided.
