CHON-YIN TSAI’s skills in computer science saved the Trident II missile.


The Trident II is a submarine-launched ballistic missile, built by Lockheed Martin Space Systems in Sunnyvale, California. It was first deployed in March 1990, and is still in service. The Trident II is considered to be a durable sea-based system capable of engaging many targets. Trident II missiles are carried by 14 US Ohio and 4 British Vanguard-class submarines, with 24 missiles on each Ohio class and 16 missiles on each Vanguard class.
