Type 5 Na-To

The Type 5 Na-To (五式砲戦車) was the penultimate tank destroyer developed by the Imperial Japanese Army in the closing stages of World War II.

History and development
Towards the end of the Pacific War, Japanese field commanders realized that nothing in the inventory of the Japanese army would be able to withstand the increasingly advanced tanks and armored vehicles fielded by the Allies, and that a more powerful version of the Type 3 Ho-Ni III was necessary. Development was rushed through on a new design, which was completed in 1945. The Japanese army immediately issued an order for 200 units to be completed in 1945. However, by that time production was impossible due to material shortages, and by the bombing of Japan in World War II, and testing was not yet completed by the end of the war.

Design
The Type 5 Na-To made use of the chassis of the Type 4 Chi-So medium tracked carrier. The superstructure had an open top and rear, with an enclosed armored drivers cab. Its main anti-tank armament consisted of a Type 5 75 mm Tank Gun which was the same gun that was used on the Type 4 Chi-To tank; a variant of the Japanese Type 4 75mm AA Gun.

Combat record
Although the Type 5 Na-To tank destroyer was intended to become part of the defenses of the Japanese home islands against the projected Allied Invasion, only two units were completed by the surrender of Japan. Neither one was used in combat.
