Hsiung Feng I
anti-ship missile system developed between 1975 and 1978
The Hsiung Feng I (HF-1) (雄風一型, "Brave Wind I") is an anti-ship missile system developed by the National Chung-Shan Institute of Science and Technology in Taiwan between 1975 and 1978 in response to the SY-1 missile being introduced into service with the opposing People's Liberation Army Navy.
Development
As NCSIST's previous experience with anti-ship missile development was limited to experimentally fitting warheads onto MQM-33B drones, the decision was made to base the weapon on the Israeli Gabriel Mk I with necessary modifications added in order to remain competitive against the SY-1 missile, making it essentially a Taiwanese interpretation of the Gabriel Mk II (and since the Republic of China Navy did also import several sets of Gabriel Mk II system to rehabilitate three of their Allen M. Sumner class destroyers, they also stipulated the HF-I to be made interchangeable with the Israeli-made ordnance).
The system uses the Taiwanese CS/SPG-21A as a target acquisition and fire control radar. The CS/SPG-21A reportedly has a range of 37 km which was later upgraded to 46 km.
Service history
The Hsiung Feng I was officially a reverse-engineered version of Gabriel Mk.2 antiship missile, although Israel is believed to have cooperated with Taiwan. Sun Yat-sen Institute and National Chung-Shan Institute of Science and Technology redesigned the missile to include Taiwanese components.
First test-fire of Hsiung Feng I was done in 1977. Initial production started in 1979. HF-I design flaws with the radar radio frequency altimeter, cooling system, and the rocket motor undermined the missile's effectiveness. Taiwan redesigned the missile to create the Hsiung Feng IA (HF-1A), which went into production in 1981.
This brief starts where responsible research should: with the source description of “Hsiung Feng I” as anti-ship missile system developed between 1975 and 1978. 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 anti-ship missile system developed between 1975 and 1978. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 30, 2025. The linked authority identifier is Q3498153. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1975, 1978, 1977 and 1979.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
