Armament

HQ 381 is a Vietnam People's Navy corvette and the only example of the BPS-500 class. The ship was designed in Russia and the first missile corvette produced in Vietnam.

Development

Vietnam began a program to modernize its military equipment in the mid-1990s following further territorial disputes in the South China Sea with China.[3] One aspect of the program was to develop domestic production and repair capability. Russia agreed to supply or co-produce small warships and missiles;[4] In 1996, Russia and Vietnam agreed to co-produce the BPS-500;[5] this may have been a part of or related to a cooperative military shipbuilding[6] or corvette program called KBO-2000.[7]

BPS-500 was designed by the Severnoye Design Bureau.[2] Two were ordered[7] and Russia supplied two kits to the Ba Son Shipyard. HQ 381 was built with modular technology,[8] launched in June 1998 and became operational in late-2001;[2] it was the first missile corvette produced in Vietnam.[4] No more were produced as the ship did not meet requirements[9] or more advanced ships became available.[10] The pump-jets raised construction and maintnenace costs and had poor performance at low speed. The hull had insufficient seakeeping for long-range operations. There may also have been software and control system problems.[8]

Severnoye was contracted to assist overhauling and upgrading the ship in 2013[6] and 2017.[11]

Description

BPS-500 is an improved Pauk-class corvette.[2] Angled surfaces reduce radar cross section. The pump-jets with directional nozzles have better maneuverability in shallow waters and generate less noise than propellers.[8]
