The Philippines Navy had mandated HHI to choose a self-protection solution that would combine advanced technology, cost-effectiveness, small footprint and high-operational flexibility.
The decoy launchers can provide 360° coverage and help counter advanced threats such as small range gate radio frequency (RF) missiles, imaging infrared (IR) seekers missiles, dual seeker threats and advanced torpedoes.
Using SeaGnat or 130mm decoy rounds, the C-Guard system will provide the Philippines Navy with protection against numerous threats, according to Terma.
The C-Guard algorithm will provide the flexibility of deploying chaff as sub-munitions or as large chaff bursts.
Also, the multi-azimuth tubes of the C-Guard system enable the algorithm to calculate precise firing of IR to provide 360° coverage.
The algorithm can calculate the heat dissemination of flare decoys and in combination with chaff decoys obscure the IR image of a naval vessel.
In addition, launchers support the firing of the new and advanced acoustic anti-torpedo decoys.
The delivery of the two frigates to the Philippines Navy is slated to commence in 2020. Once in-service, the Philippines Navy vessels will replace the existing Incheon-class frigates.
Designed to be a smaller light combatant, the future frigates will be capable of conducting anti-air / surface / submarine warfare and electronic warfare missions.
