center (with data-link), mobile surface search radar and portable electric generators, were kept in harden shelters and being driven out when needed. The HF-2 mobile launchers, shown in 10 October 2007 parade, was designed to be able to carry both HF-2 and the new HF-3 AShM, by leaving room for the larger HF-3 missile boxes. Same was done to the /'s new HF-2 launchers after each frigate's major overhaul, starting 2001, that allows the launcher to carry larger HF-3 AShM, besides HF-2. The s (total 12 built) also are undergoing the same upgrade to carry two twin-mounted HF-2/3 anti-ship missiles. The s (total 31 built) carry two twin-mounted HF-2 anti-ship missiles. The s also carry four quad-mounted HF-2/HF-3 anti-ship missiles. A submarine-launched version was planned and designed in the mid-1990s, but nothing more was heard. Block II In late 2014, CSIST reportedly began the test-launching stage of an extended-range version of the HF-2, increasing range from to ; the range increase was successfully achieved by February 2017. In 2019 mass production of an improved Block IIB was approved with production to be completed by 2023. Future development HF-2B In November 2019 NCSIST tested a new short range anti-ship missile which while weighting significantly less than the Hsiung Feng II is said to have the same range. The test was conducted using NCSIST’s Glorious Star test ship. The provisional designation is HF-2B and production is scheduled to begin in 2021. The reported range of the HF-2B is 250km.
