Wartime Naval Armaments Supplement Programme
wartime Naval Armaments

The Wartime Naval Armaments Supplement Programme (マル戦計画, 昭和十八年度戦時艦艇建造計画, Maru Sen Keikaku, Shōwa-Jūhachi-Nendo Senji Kantei-Kenzō Keikaku) was the 1943-44 War Programme to fund further wartime armaments expansion plans of the Imperial Japanese Navy (IJN).
Background
Due to shifting wartime circumstances, the IJN focused on the construction of auxiliary and escort ships. As a result, the Wartime Naval Armaments Supplement Programme lacked any major warships capable of offensive operations.

This brief starts where responsible research should: with the source description of “Wartime Naval Armaments Supplement Programme” as wartime Naval Armaments. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as wartime Naval Armaments. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jan 26, 2025. The linked authority identifier is Q7971036. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1943, 1944, 1945 and 1988.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
