Comparing: T1 Cunningham vs. Renault NC-31 vs. Renault Otsu

The experimental T1E1 light tank designed by the Cunningham company was a further development of the T1 tank. By April 1928, four vehicles were produced. After the vehicle underwent trials in November 1928, a decision was made to enhance the armor, which led to creating the subsequent modification designated the T1E2.

The NC-2 project (commercial name NC-31) was a modification of the Renault FT-17 tank featuring a soft ride suspension and a Kegresse-Hinstin fanged rubber track. These features, along with an upgraded engine, gave an increased top speed of 16 km/h. A total of 15 vehicles of this type were exported to China.

Developed from 1925 through 1928 in France as an upgraded modification of the Renault FT. The modernization project was finished and the vehicle saw mass production. In 1929, a total of 10 vehicles were purchased by Japan and were designated the Otsu-Gata Sensha (Tank B Model). The Japanese vehicles were slightly modernized and were widely used both in action and for training purposes.
