Hsiung Feng II

The Hsiung Feng II (HF-2) (雄風二型, "Brave Wind II") is an anti-ship missile system developed by the Chungshan Institute of Science and Technology 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 frigates and Lafayette class frigates, as well as at several land-based sites. In 2000, plans were announced to replace the HF-2 missiles stationed on the Cheng Kung frigates with the RGM-84 Harpoon, but the budget for this was cancelled.

In 2001 a land attack cruise missile variant known as the HF-2E was announced, mass production of the HF-2E began in 2005.

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 trial vessel. Later all major surface combatant in RoCN, except the Knox, were equipped with 2 quad-launchers, plus the 7 WWII era Gearing DDGs that was upgraded to WC3 standard, from late 1980s to mid 1990s, had added a 1 quad-launcher by mid 1990s to give those air defense ships an anti-surface ability.

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 missile designed for one aircraft cannot fit on another aircraft. Unknown if air-launched HF-2 program is continuing at this point.
