The Hsiung Feng II (HF-2; Chinese: 雄風二型; pinyin: Xióngfēng èr xíng, "Brave Wind II") is an anti-ship missile system developed by the National Chung-Shan Institute of Science and Technology (NCSIST) in Taiwan. The HF-2 is designed to be deployed aboard ships or at facilities on land. An airborne version has also been developed which can be carried by the ROC Air Force's F-CK fighters. The HF-2 has ECCM capabilities and is deployed on the ROC Navy's Cheng Kung-class and La Fayette-class frigates, as well as at several land-based sites.

There are three major versions of HF-2 in service. The first to enter service is the ship-based HF-2, with 2 twin box launcher on destroyer DD-915 first as a trial vessel. Later all major surface combatant in RoCN, except the Knox, were equipped with 2 quad-launchers, plus the 7 World War II-era Gearing-class guided missile destroyers that was upgraded to WC3 standard, from the late 1980s to mid-1990s, had added a 1 quad-launcher by mid-1990s to give those air defense ships an anti-surface ability.

An air-launched version appeared in the early 1990s. Carried by two AT-3B trainer/attacker and a single A-3 attacker, the small force poses little threat to the marine intruders due to its small quantity. However, the recent upgraded IDF (F-CK-1C/D) will add the capacity to carry and launch the HF-2, thus greatly enhance the air-to-surface capacity of RoCAF in future. The air launcher version of HF-2 carried by AT-3 is different from the one supposed carried by original IDF (F-CK-1A/B) prototype, due to differences in length of the HF-2 missile (better known as HF-2 Mark 3 and Mark 4), where the rocket designed for one aircraft cannot fit on another aircraft. Unknown if air-launched HF-2 program is continuing at this point.

The land-launch version of the HF-2 is the most secretive one because of its relation with the land-attack version of HF-2E. Fixed base versions were produced first, and all major outlying islands of Taiwan were equipped with fortified HF-2 bases in the late 1990s, replacing old HF-1 bases. Fixed HF-1 bases in the main island were also being replaced with fixed HF-2 launchers, again in fortified positions.

The mobile launcher version was accepted in 2005 and went to mass production in 2006. All mobile launchers, together with mobile command center (with data-link), mobile surface search radar and portable electric generators, were kept in harden shelters and being driven out when needed. The HF-2 mobile launchers, shown in 10 October 2007 parade, was designed to be able to carry both HF-2 and the new HF-3 AShM, by leaving room for the larger HF-3 missile boxes. Same was done to the Oliver Hazard Perry/Cheng Kung-class frigate's new HF-2 launchers after each frigate's major overhaul, starting 2001, that allows the launcher to carry larger HF-3 AShM, besides HF-2. The Ching Chiang-class patrol ships (total 12 built) also are undergoing the same upgrade to carry two twin-mounted HF-2/3 anti-ship missiles. The Kuang Hua VI-class missile boats (total 31 built) carry two twin-mounted HF-2 anti-ship missiles. The Tuo Chiang-class corvettes also carry four quad-mounted HF-2/HF-3 anti-ship missiles.

A submarine-launched version was planned and designed in the mid-1990s, but nothing more was heard.

In late 2014, CSIST reportedly began the test-launching stage of an extended-range version of the HF-2, increasing range from 160 km (99 mi) to 250 km (160 mi);^[1] the range increase was successfully achieved by February 2017.^[2]

In 2019 mass production of an improved Block IIB was approved with production to be completed by 2023.^[3]

In 2019 Sputnik News and other began propagating a conspiracy theory that the Argentinian submarine ARA San Juan had been sunk by a Taiwanese HF-2 anti-ship missile used by international mercenaries working for multinational oil companies.^[6]
