Sky Spear


The Sky Spear is a Taiwanese short-range ballistic missile. Derived from the Sky Bow II surface-to-air missile, the Tien Chi has a two-stage booster that extends over the single-stage Tien Kung-2. The Sky Spear was developed by the Chungshan Institute of Science and Technology in Taiwan. As of early 2001, up to 50 Tien Chi missiles were deployed at two sites: Tungyin Island, and an unidentified second location. The Tungyin Island missiles are said to be housed in silos and protected by batteries of Tien Kung-2 SAMs.

Description

Information provided by CSIST to Jane's Missiles and Rockets, revealed that Tien Chi uses a submunition warhead and there is no unitary warhead for this missile. According to this report, Tien Chi was developed by CSIST following test firings of a Tien Kung 2 variant with a 120 km range and a 90 kg HE warhead. The report also credited Tien Chi missile with a range of 300 km and a 500 kg payload. This range is well beyond the reported 200 km maximum range of the Tien Kung II SAM system, but since Tien Chi is used in a tactical surface-to-surface missile role, it would fly a more efficient trajectory with no need for energy-consuming manoeuvres. Guidance is believed to be an integrated INS/GPS system.

History

It has been reported that Taiwan has deployed 15-50 missiles on Tungyin and Penghu.

Variants

According to the Taipei Times retired president of NCSIST Kung Chia-cheng claimed that two variants were developed, one with a range of 600km and the other with a 1000km+ range. Taiwanese President Chen Shui-bian was reportedly very surprised by how large the missiles were when he went to inspect them.
