The Japanese Type 75 155mm Self Propelled Gun

The Japanese Type 75 155mm Self Propelled Gun is the current principal artillery Self Propelled Gun of the Japanese Ground Self Defence Force. it’s a much larger and more powerful in lethality compared to the Type 74, but is not a replacement as Japan is a cluster of nearly 7000 islands! And about 70% to 80% of the country is forested, mountainous and unsuitable for agricultural, industrial, or residential use.

Japan is one of the most densely populated countries in the world, which means space is at a premium and there are limitations on its transportation network. Both these factors mean it has to operate a mixture of vehicles (including tanks) of varying size. The main gun is 155mm in bore calibre and 30 calibre in length.

The Type 75 design was almost parallel time wise, running prototypes were completed in 1972 and differed only in their loading systems. Trials were conducted 1973-4 and the howitzer was accepted for service in October 1975. Some publications claim that only 200 were built, however 201 were reported to be in service in 2008.
