The Temporal Naval Armaments Supplement Programme (マル臨計画, 情勢ニ応ズル軍備欠陥補充, Maru Rin Keikaku, Jōsei ni ouzuru Gunbi-Kekkan Hojū) is one of the armaments expansion plan of the Imperial Japanese Navy (IJN).
In October 1940, the IJN schemed building of the submarines and auxiliary vessels because there was a shortage of them.
