Due to their adoption of an offensive doctrine, the Imperial Japanese Navy did not invest much of their resources into developing mines which were seen as defensive weapons[1]. The Japanese were also minimally effective in countering mines as their main Pacific base at Rabaul, New Guinea only had three minesweepers as late as 1943[2]. While stagnant, the IJN still maintained a collection of moored contact mines such as the Type 93 mod.1.

The Type 93 mine was built to replace the IJN's ageing Type 5 contact mine from World War I[2]. The Type 93 boasted both a larger overall mass (1,543 lbs to the Type 5's 1,146 lbs) and explosive charge (220 lbs compared to the Type 5's 183 lbs), but also in the composition of the explosives. Type 5 used a picric acid charge, but Type 93 used the Type 88 explosive, a mixture of 66% ammonium perchlorate, 16% ferrosilicon, 12% wood pulp, and 6% oil. As the name suggests, Type 88 explosive was created in 1928 (2588 for the Japanese Imperial Calendar) and first implemented in the Type 93 mine[1].

The Type 93 mod.1 mine was designed with the ability to be air-dropped. As they used the Hertz Horn triggering mechanism which requires direct contact, the Type 93 mines were short-range weapons. The IJN countered this issue by tightly packing mines in chokepoints[1]. However, the effectiveness of the Type 93 mod.1 and similar mines was ultimately ineffective against the United States Navy. The perceived lack of threat from Japanese mines led the US Office of War Mobilization to complain about the overproduction of minesweepers[2].


Excellent additions to the article would be video guides, screenshots from the game, and photos.
