According to the Philippine Navy, their newest frigates BRP Jose Rizal and BRP Antonio Luna will be equipped with Korean anti-ship missiles, which will be the SSM-700K Haeseong.

Introduce

SSM-700K Haeseong, also known as C-Star, is described as a “sea-skimming surface-to-surface anti-ship cruise missile”.

Haeseong was developed by the South Korean Agency for Defense Development (ADD) from 1996 to 2003 at a cost of around 100 billion WON. The production missile model was originally designated as the SSM-700K, but the missile currently in service with the South Korean Navy is designated as the SSM-710K.

The missiles are deployed on KDX-II and KDX-III destroyers as of 2006, each carrying 8 and 16 of the missiles respectively, and on Ulsan-class frigates.

Design and Performance

Each C-Star missile costs about 1.72 million US dollars. By design, the C-Star has a weight of 718kg, a length of 5.46m, a width of 0.34m, and a warhead of 250kg.

Back in 1996, ADD started developing Radar Seeker for C-Star, but the first domestic radar could not meet the required operability. ADD instead imported the Radar Seeker Ku Band of the Exocet MM40 Block III anti-ship missile and integrated it on the first C-Star batch.

At the time, Exocet’s Radar Seeker Ku Band boasted higher resolution than the Radar Seeker X Band, popular on the RGM-84 Harpoon anti-ship missile, allowing it to more effectively identify and attack enemy warships.

Based on Exocet, the SSM-700K C-Star can do the same thing, combined with the new native algorithm and GPS navigation, its integration onto small patrol boats is also significantly improved compared to Exocet. The C-Star has an “Impact Fuze” detonation mechanism not commonly found in Western anti-ship missiles, allowing it to sink small patrol boats with one hit without penetrating the hull.

Testing

C-Star has proven itself to be a high precision weapon system. In the tests, C-Star has yet to miss a target until 2016 when a series of errors occurred at home and abroad. In 2016, for the first time, C-Star failed its target since its inception. The problem was said to be a mechanical fault of the launcher. The ROKN then modifies all of its launchers to fix the problem.

The next incident took place in 2018 with the Colombian Navy, two C-Star missiles failed to hit the target in a live-fire test in the presence of the President of Colombia. Issues resolved in 2019.
