The Kasturi-class corvettes are two ships of the Royal Malaysian Navy, KD Kasturi (F25) and KD Lekir (F26). They were acquired in the mid-1980s. The two ships constitute the Malaysian Navy's 22nd Corvette Squadron, their homeport being Lumut. After about 25 years of service, they underwent an extensive modernisation known as Service Life Extension Program (SLEP) starting in 2009, enabling them to be employed for another 10 to 15 years. They have since been returned to active duty.
The two ships of the class are named after Hang Kasturi and Hang Lekir, two heroic figures from the Malay 15th-century epic narrative Hikayat Hang Tuah. They share this characteristic with the two Lekiu-class frigates KD Lekiu and KD Jebat, as well as the old frigate-turned-trainingship KD Hang Tuah, all of which are named after figures from the epic as well.
