The nihongo|Type 4 Ha-To|試製四式重迫撃砲（ハト）| Shiseiyon Jyūhakugekihō Ha-To was a self-propelled gun developed by the Imperial Japanese Army for use in World War II

History and design

The Type 4 Ha-To was conceived as a mobile fire support platform in late 1943, making use of the already existing Type 3 300mm heavy Mortar on a chassis based an extensively modified Type 4 Chi-To medium tank. The mortar had a range of 3,000 meters (1.9 miles) and launched a 170 kg (374 lbs) projectile. The gun itself weighed close of 1.5 tons, and to keep the center of gravity from shifting and tipping the vehicle over, it could not be elevated more than 50 degrees. [Japanese wikipedia article]

The first prototype was completed in late 1944 and taken to the Imperial Japanese Army Academy for testing. Although testing indicated that it would be effective weapon, it was expensive to produce, and the Japanese Army Technical Bureau shifted its attention to self-propelled multiple rocket launchers instead.

An additional three units were produced before the surrender of Japan, but none were used in combat. [Trewhitt, Armoured Fighting Vehicles ]
