The SU-14 was a prototype Soviet heavy self-propelled gun built on a T-35 chassis. The original prototype mounted a 203 mm howitzer M1931 (B-4); the SU-14-1 variant of 1936 carried a 152.4 mm Br-2 (also called Model 1935) cannon which could fire 43.5 kilogram shells at ranges up to 20 km. Its armour was 20 to 30 mm thick. It never entered serial production. Work on the vehicle began in 1933, with a prototype built a year later. In 1935, several disadvantages were reworked and another prototype was built and designated SU-14-1. In February 1937, the prototypes successfully completed a series of performance tests. It was expected to go into production the following year. However, in 1937, Chief Designer - PN Siaczyntowa was removed from the program, thus halting further development of the project. In 1940, in connection with plans to use them during the war with Finland, armor was added to the two existing prototypes and they were redesignated SU-14-2. They later took part in the defense of Moscow in 1941 alongside the prototype SU-100Y. The first one (the original SU-14 prototype) was scrapped in 1960. The second prototype, as an SU-14-2, is on display at the Tank Museum in Kubinka. ==Gallery== File:SU-14 before the firing test, 1934.jpg|SU-14 before the firing test, 1934 File:SU-14 with gun coverd, in trial for navigation, 1934.jpg|SU-14 with gun covered, in trial for navigation, 1934 File:SU-14 in the courtyard of the factory No 185, 1934.jpg|SU-14 in the courtyard of the factory No 185, 1934 File:Prototype of SU-14-1 in trial, 1936.jpg|Prototype of SU-14-1 in trial, 1936 File:Enhanced armoured SU-14-Br-2 in trial at Kubinka, 1940.jpg|Enhanced armoured SU-14-Br-2 in trial at Kubinka, 1940 File:Самоходная установка СУ-14-2 в Кубинке 01.JPG|Self-propelled gun SU-14-2 armored museum in Kubinka 01 File:Самоходная установка СУ-14-2 в Кубинке 02.JPG|Self-propelled gun SU-14-2 armored museum in Kubinka 02 File:Самоходная установка СУ-14-2 в Кубинке 03.JPG|Self-propelled gun SU-14-2 armored museum in Kubinka 03 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SU-14」の詳細全文を読む スポンサード リンク
