This is a Japanese-made, distinctive "Midget Submarine."
This can be utilized by light cruisers, seaplane tenders remodeled as midget submarine tenders, and submarines.
Equipped with two torpedoes, this is a unique weapon that can approach and attack enemy ships in order to support open-sea warfare.


This equipment allows any ship equipped with it to perform opening torpedo attacks. Submarines Lv.10 or higher can preform opening torpedo attacks without a Midget Submarine.

Does not count as a torpedo for cut-ins during night battle despite having a torpedo icon.

1xAction Report


The Type A Ko-hyoteki, which means "Target 'A', Type 'A'," was given its name in order to disguise its true purpose: if its design was discovered prematurely by Japan's foes, the Japanese Navy could insist that the vessels were practice battle targets. They were also called "Tubes" (筒 Tou) or "Target" (的 Teki, abbreviation of 'Hyōteki') and other slang names.

Five of these participated in the attack on Pearl Harbor, with two actually making it into the harbor. They also participated in the attacks at Sydney Harbor, as well as in Madagascar.
