Taiwan Successfully Completes Initial Phase of Tien Kung IV Missile Tests

Taipei – Taiwan has completed the initial test phase of its next-generation Tien Kung IV (Sky Bow IV) missile system, signaling a significant leap forward in the nation’s self-reliant defense capabilities. The move comes amid increasing security concerns and geopolitical tensions in the Indo-Pacific region.

Developed by the National Chung-Shan Institute of Science and Technology (NCSIST), the Tien Kung IV is Taiwan’s most advanced surface-to-air missile to date. Designed to intercept high-speed, high-altitude aerial threats — including ballistic missiles and advanced fighter aircraft — the system is a critical addition to Taiwan’s integrated air and missile defense network.

The initial trials included evaluations of the missile’s propulsion, flight path stability, and interception capabilities. According to defense officials, the tests were conducted successfully and provide a solid foundation for future phases of development and deployment.

This achievement is particularly significant as Taiwan continues to bolster its defensive posture in response to growing military pressure from mainland China. The completion of these tests underlines Taiwan’s commitment to advancing indigenous defense technologies and reducing dependency on foreign weapon systems.

Experts note that the Tien Kung IV fills a crucial gap in Taiwan’s current defense infrastructure, offering capabilities similar to the American Patriot missile system but developed locally to suit regional needs and terrain.

The Tien Kung IV features a dual-stage propulsion system, extended range capabilities, and enhanced guidance systems to detect and destroy fast-moving targets. It also integrates with Taiwan’s existing radar and command systems, making it a versatile tool in Taiwan’s multilayered defense strategy.

Defense analysts believe this system could play a pivotal role in Taiwan’s missile shield strategy, especially if fully deployed across critical military bases and civilian areas.

With the preliminary testing phase successfully completed, the missile system will undergo further evaluations and improvements. Mass production and phased deployment could begin within the next few years, further strengthening Taiwan’s military readiness.

As tensions continue to mount across the Taiwan Strait, the success of the Tien Kung IV testing is not just a technical achievement — it’s a strategic message.
