Funryu
type of surface-to-air missile

Funryu (奮龍, Funryū) were a series of surface-to-air anti-aircraft missiles developed in Japan at the end of the Second World War. The missile's development in the late stages of the war was plagued by organizational problems and cancelled before becoming operational.
In 1945, a few samples of SAM Funryu were created and tested, but due to the surrender of the Japanese Empire, had not been finalized. All the developments on the complex were destroyed after the end of hostilities.
The first design was the Funryu 1, an air-to-surface missile (ASM) specialized for anti-shipping use. Funryu 1 was much like a miniature airplane. The warhead contained 400 kg (882 lb) of explosive and guidance was via radio control. Testing of the Funryu 1 was conducted with the missile being dropped from a modified Mitsubishi G4M bomber. However, since perfecting the methods of controlling the missile in flight would take significant time and US bombing raids against Japan were intensifying at the time, it was decided that efforts should be directed towards surface-to-air missiles (SAMs). Thus, the Funryu 1 was shelved and became the only ASM of the Funryu family.
The public source identifies “Funryu” as type of surface-to-air missile. This brief keeps that definition visible, then builds a research path around Funryu, type and surface-to-air.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Funryu”, the useful work is to connect “type of surface-to-air missile” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 11, 2023. The linked authority identifier is Q4493460. The Library of Congress control number is sh85052482. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1945.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
