Kaibōkan

Main article: Kaibōkan

Matsuwa in 1943

Escort ship CD-1 in 1944

Kaibōkan was originally a catchall term used by the Imperial Japanese Navy for obsolete warships which had been relegated to coastal defense duties. As a consequence of the London Naval Treaty, the Imperial Japanese Navy was constricted on the total tonnage of destroyers it was allowed to build, so Japanese naval planners designed a new class of vessel to take advantage of a loophole in the treaty which permitted ships of between 600 and 2,000 tons, with no more than four guns over 76 mm (3.0 in), no torpedoes, and a maximum speed of 20 knots, and gave them the obsolete designation of kaibōkan to further ensure that they would not be considered as destroyers. These ships were roughly equivalent to contemporary Allied destroyer escorts and frigates.
