TAIPEI (Taiwan News) — An unexploded WWII bomb was discovered Monday (Nov. 11) at the construction site for Taiwan Semiconductor Manufacturing Co.'s (TSMC) new fab in Kaohsiung's Nanzih Technology Industrial Park—the second such discovery in less than three months.

At 9:35 a.m., construction workers unearthed the bomb at a section of the former CPC Corporation Kaohsiung Refinery, which is being cleared for TSMC’s new facility, per SET News. The Army later identified it as the remains of a 500-pound bomb.

The 8th Army Corps Command was alerted at 10:45 a.m. and dispatched a specialized unit to handle the ordnance. Upon arrival, the team confirmed it was a WWII-era bomb used by the US military, with a rusted casing, damaged fuse, and an indiscernible batch number. Experts assessed that the bomb posed no immediate safety risk.

By 11 a.m., the team had defused the bomb and transported it to a temporary storage facility for unexploded ordnance in Kaohsiung’s Zuoying District. According to the Kaohsiung City Government Public Works Bureau, work at the construction site remains unaffected.

On Aug. 26, an unexploded 1,000-pound AN-M65 bomb was also found in the western sector of the old Kaohsiung Refinery. A city official noted that the area was previously a Japanese oil depot frequently targeted by US bombers.

The official added that unexploded bombs have been uncovered during past renovations at the old refinery site.
