Development
The development of the Sky Bow 1 (Tien Kung 1) missile system was started in 1981 by the Chungshan Institute of Science and Technology (CSIST). Firing trials started in 1986, using a semi-active radar seeker. A passive IR terminal seeker was also developed as a secondary seeker for the TK-1, this was successfully tested against a HAWK missile target but never put in the production missile. CSIST also developed a large multifunction, phased-array radar known as Chang Bai (long white) for use with the Tien Kung (Sky Bow) series surface-to-air missile systems with 120 degree coverage and a maximum range of 450 km. Two versions of the phased array radar exist, a towed trailer radar and fixed "hardened" radar sites.
The Chang Bai radar system is reported to be based on the Lockheed Martin's ADAR-HP (Air Defense Array Radar-High Power) design and operates in the 2–4 GHz range (S-band). At least seven systems are said to be currently in service. The system performance specifications remain classified, but its reported effective detection range against 1m2 target to be around 400 km.
There was also a mobile version of the phased array radar developed in the late 1990s which could provide all-round radar cover with four separate faces but with a much decreased detection range. This version only appeared in public once but was never put into service. The development of Sky Bow 2 started around 1986, this added a tandem boost motor and an active radar terminal seeker. Proposals were reported to develop Sky Bow 2 into a surface-to-surface missile; unconfirmed reports suggest that this missile is known as Tien Chi. Modifications have been developed for Sky Bow 2, changing it into a single stage rocket and to provide it with a limited capability against shorter-range ballistic missiles; the first test firing against a ballistic missile target was reported in September 2008. Seven batteries of TK-1/2 SAMs are in service and deployed throughout Taiwan, on the Pescadores, and Dong Ying island.

Famous quotes containing the word development:
“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.”
—Lawrence Kutner (20th century)
“... work is only part of a man’s life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877–?)
“The proper aim of education is to promote significant learning. Significant learning entails development. Development means successively asking broader and deeper questions of the relationship between oneself and the world. This is as true for first graders as graduate students, for fledging artists as graying accountants.”
—Laurent A. Daloz (20th century)
