The disclosure comes as the government prepares another attempt to secure funding after the system was excluded from a pared-back special defence spending package approved by the opposition-controlled legislature in May.
The defence ministry plans to resubmit Strong Bow and other programmes through a supplementary budget, which the cabinet could consider as early as Thursday before sending it to lawmakers.
The ministry has proposed spending NT$36.1 billion (US$1.13 billion) to produce two Strong Bow systems and 128 interceptor missiles.
Strong Bow, also known as Tien Kung (Sky Bow) IV, is a land-based mid-tier anti-tactical ballistic missile system designed to intercept incoming missiles at altitudes of at least 70km (43 miles) – higher than Taiwan’s existing Patriot and Tien Kung III systems.
According to NCSIST, the vertically launched missile can reach hypersonic speeds and uses a two-stage solid-fuel rocket motor. It relies on inertial guidance and radar uplink corrections during midcourse flight before switching to an active seeker in the terminal phase.
