The Drive/The War-Zone reports,
During the test conducted on May 23, officials said that the HF-2 missiles were launched from the cutter off the coast of the Jiupeng Base and successfully hit a target ship that was located 62 miles off the coast of Lanyu, near Orchid Island. According to Taiwan’s Liberty Times Net reporter Zheng Jingyi, “this live ammunition firing specifically verifies the integration of the naval forces and sea cruisers under the ‘peace-to-war conversion.’”
This was a test and the missile launch equipment was removed immediately after the test. The launch and control was conducted by Taiwanese Navy personnel, temporarily assigned for the test.
Since the cutters are a version of a missile equipped Taiwanese Navy corvette, there would seem little reason to believe the test would not have been successful.
Reportedly twelve corvettes and twelve cutters are planned, but the prototype Navy corvette was commissioned in 2014, the second not until 2021, and none since. On the other hand four of the cutters have entered service beginning 2020 with two more under construction.
The normal armament of these and other Taiwanese cutters includes an unusual 42 round, remote controlled, “Zhenhai” 70mm/2.75″ rocket launcher. It is unclear if these rockets have a guidance system like APKWS. Photos below from Wikipedia.
