The type 90-240 mm railway gun ( Japanese 九 〇 式 二十 四 糎 列車 加 農 , Kyūrei-shiki nijūyon-senchi Ressha Kanon ) was a railway gun used by the Imperial Japanese Army in the Second Sino-Japanese War from 1930 to 1945 was used. The designation Type 90 indicates the year the troops were introduced, the year Kōki 2590 or 1930 according to the Gregorian calendar.
history
In 1926 the Imperial Japanese Army acquired a 240 mm cannon barrel from the French company Schneider-Creusot (converted to Schneider Electric after World War II ) to manufacture a railway gun. The rest of the components needed to complete the gun were made in Japan . The barrel was delivered in 1928 and the finished railway gun was handed over to the troops in 1930.
Originally designed for coastal protection in the Tokyo Bay , the gun was provided in 1941 in the Manchuria to the fortress Koto (Ch. Hutou , Hulin moved) to the Japanese defense in case of a Soviet strengthen attack. The Japanese army had eight fortresses built along the border with the Soviet Union, of which the Kotō fortress on the Ussuri River was the strongest. Large-scale fortifications, similar to the Maginot Line , were guarded by the 4th Border Guard Unit. The 1400-strong crew had two batteries of field guns and howitzers as well as the experimental 41 cm howitzer and the Type 90 railway gun .
At the beginning of 1945 the 15th Border Guard took over the Kotō fortress. When the Soviets overran the Japanese positions in Operation Auguststurm in August 1945 , the Type 90 gun was changing position. The gun operation then destroyed the Type 90 and gave it up.
technology
A special feature of the Type 90 railway gun was its 360 ° directional range. As soon as the gun carriage was standing, the rotating mount on which the gun was resting could be swiveled through 360 °. Other railway guns , on the other hand, required a firing curve in order to fight different, laterally offset targets. The carriage rested on a railway wagon with two five axles (a total of 20 wheels). The gun was pulled by two locomotives.
