IDF-II "Hsiung Ying" ("Goshawk")
The Aerospace Industrial Development Corp (AIDC) launched the seven-year Hsiang Sheng (Soaring Upgrade) program in 2000, when the Cabinet allocated $225.5 million to turn two air-interdiction IDFs into "joint strike fighters" with longer range and larger payloads. The most prominent change on the Indigenous Defence Fighter II “Goshawk" fighter aircraft is the conformal fuel tank clearly visible above the wing.
The upgrade allowed the IDF to carry an extra 771 kilograms of fuel and payload, doubles the loadout of Tien Chien 2 (Sky Sword) air-to-air missiles to four, and added the ability to carry the Tien Chien 2A anti-radiation missile and the Wan Chien (Ten Thousand Swords) bomb, both produced by the military-run Chungshan Institute of Science and Technology (CSIST). It also upgraded the mission computer, electronic warfare system and radar.
An undated handout photo made available 09 October 2006 by Taiwan's military-owned aircraft maker Aerospace Industrial Development Corporation (AIDC) showed a prototype of the improved version of the home-grown Indigenous Defence Fighter. The prototype has four air-to-air missiles, an improved anti-radiation missile and a "Wan Chien" (Ten Thousand Swords) cluster bomb. The plane would also have upgraded mission computers, electronic warfare systems, an advanced "identification friend or foe" system and improved terrain-following and radar systems.
Taiwan on 09 April 2007 unveiled an upgraded home-made fighter jet which President Chen Shui-bian said demonstrated the island's determination to defend itself against rival China. A prototype of the sleek twin-seater fighter, an improved version of the Ching-Kuo Indigenous Defence Fighter IDF-II, scrambled for take-off at the Chingchuankang airbase in central Taiwan.
Referring to the modified Indigenous Defense Fighter-II (IDF-II) "Hsiung Ying" ("Goshawk"), President Chen Shui-bian said in March 2007 he hoped the new model would protect the homeland with the ferocity of a Taiwan goshawk. The military unveiled the upgraded version of its locally produced indigenous defense fighter (IDF) warplane, to help boost the nation's defenses against China until Taipei can purchase more modern fighter planes from the West. Vice President Annette Lu, who accompanied Chen to the test flight and naming ceremony at the AIDC in Taichung County, mistakenly referred to the new model as the "Taiwan bald eagle."
Costing the military seven billion Taiwan dollars (212.12 million US) in a project launched in 2001, the Goshawk had increased its endurance time with the installation of two additional fuel tanks, the AIDC said. The new fighter has upgraded mission computers and an advanced fire control radar system, and will be armed with four medium-range air-to-air missiles, it said, adding service entry was scheduled for 2010 if further development was successful.
AIDC launched the IDF-II Xiang Sheng (Soaring Upgrade) program in 2000, when the Cabinet allocated $225.5 million to transform two air-interdiction IDFs into strike fighters with longer range and bigger payloads. The IDF-II can carry an additional 771 kilograms of fuel and payload, doubles the load of Tien Chien 2 (Sky Sword) air-to-air missiles to four, and adds the ability to carry the Tien Chien 2A anti-radiation missile and the Wan Chien (Ten Thousand Swords) cluster bomb.
The Wan Chien (Ten Thousand Swords) is Taiwan’s first joint standoff weapon, was unveiled in January 2013. Modeled after the US-built AGM-154 and the European-built Storm Shadow, the missile is meant to allow Taiwan’s Indigenous Defense Fighter (IDF) to attack runways. This will allow Taiwan to take any fight with China “downtown". By 2014 the IDF was waiting to begin upgrades of its second wing to handle the Wan Chien. The first wing of IDFs finished its mid-life upgrade program in 2013.
Despite the completion of the upgrade project, as of 2016 the military had yet to decide on whether to further upgrade the island's existing IDF fleet.
