T-65 155mm howitzer

The T-65 155mm howitzer was originally named Type 65. In 1983, it was changed to T-65 according to the guidelines for the development of weapons and equipment by the national army. The T-65 imitated the American M-114A1 155mm howitzer.

The M-114 is derived from the M-1 155mm howitzer that was finalized in 1941. It is also an old design. It uses a 23-times-diameter barrel and has a maximum range of only 14,600 meters. Important weight, but the Army has always wanted to seek a new type of 155mm howitzer. The South African G-5 155mm howitzer was originally selected, but it fell through due to diplomatic changes. Since then, with the implementation of the Jingshi case and the introduction of the M109 self-propelled artillery A2/A5 155mm self-propelled artillery vehicle, although the Republic of China Joint Service Arsenal has also developed a new 155mm howitzer, but it only stays in the prototype.

Chen Hu once served as the chief engineer of the joint logistics. Under his leadership, Taiwan's artillery factory Lianqin 202 Factory made continuous achievements in the 1970s, and successively imitated the American-made M101 105mm howitzer and M114 155mm howitzer, named 63A and 65 howitzers ( They are all calculated according to the chronology of the Republic of China), mass-produced and equipped with the Taiwan military, which solved the problem of exhaustion of the service life of the US-aided World War II artillery received by the Taiwan military in the 1950s. Of course, with Taiwan's technical level, it would be useless to create a new artillery piece from scratch, so it was still necessary to imitate advanced artillery pieces from other countries.

The imitation process of the T-65 is different from the Type 63A. After the 11th Institute of the Joint Logistics 202 Arsenal (recoilless gun institute) completed the research and development task of the 105mm howitzer of the Type 63 A, Chen Hu, the director, accepted the reverse engineering imitation in early 1975. The mission of the M-114A1 155mm howitzer, in the absence of a design, Colonel Chen Hu and his colleagues spent five months disassembling and assembling an M-114.

After that, imitation was carried out without special tools. For example, the rifling line of the 155 gun barrel was pulled out with the 106 recoilless gun's wire puller overcoming all difficulties. It was first opened at 3 o'clock in the morning on March 23, 1976. The final assembly of the 155mm howitzer is completed. The imitation was completed within 8 months, and the test firing was carried out on the same day and the test firing was successful.
