history
The Type 97 90 mm infantry mortar is based on the technology of the Stokes mortar , which could fire grenades weighing 5.26 kg up to 3800 meters in steep fire. It was very similar to the American M1 mortar and the Japanese Type 97 81 mm infantry mortar . The Type 97 is approx. 50 kg lighter than the predecessor model Type 94 90 mm infantry mortar . The weight reduction could be achieved by omitting the recoil mechanism . The weight of the bipod has also been reduced by 6 kg. While many parts of the Type 94 mortar were still made of brass , only steel was used in the Type 97 mortar . The grenades could be fired with impact or delay fuses.
600 copies of the Type 97 90 mm infantry mortar were produced.
