KD Kelantan (F175) is the fifth ship of Kedah-class offshore patrol vessel of the Royal Malaysian Navy.

[1] After receiving government approval, the Malaysian Navy ran a competition for the design in 1996, planning to purchase 27 vessels over 15 years.

The specifications aimed for a design with a displacement of 1,300 tons and an overall length of 80 m. It was already noted at that time that this resembled full-fledged corvettes rather than patrol vessels, but the eventual winning bid would turn out to be even larger.

[3] Other contenders were the German Naval Group consortium as well as British shipyards Vosper Thornycroft and Yarrow Shipbuilders.

It is capable to track 400 air and surface targets with the detection range up to 200 km and the corresponding update times between 1 and 6 seconds.
