1970s onwards In 1977, the RMN acquired the frigate HMS Mermaid from the Royal Navy to replace the decommissioned Hang Tuah. The ship was also named , but retained HMS Mermaids pennant number of F76. Hang Tuah is a 2,300 standard ton light patrol frigate armed with twin 102 mm guns. Hang Tuah gradually reverted to a training role and continues in that role for the RMN. (ex-Hang Jebat) (F24) joined the RMN in 1972. The 2,300-ton ship was a one-off Yarrow light frigate design for the RMN. The ship was originally named Hang Jebat but renamed after initial propulsion problems during pre-commissioning trials. It was the first Malaysian naval vessel equipped with a missile (Seacat) system. Rahmat was decommissioned in 2004. The RMN purchased several types of missile boats in the 1970s and 1980s. These were four Perdana-class missile boats purchased from France and four Handalan-class missile boats purchased from Sweden. Both classes were armed with the Exocet MM38 missiles. The RMN also acquired two 1,100-ton Musytari-class offshore patrol vessels of Korean design. Sealift requirements were met by the purchases of several ex-United States Navy World War II-era LSTs. KD Sri Langkawi (A1500), ex-, KD Sri Banggi (A1501), ex-, and KD Rajah Jarom (A1502), ex-, were replaced by KD Sri Indera Pura (1505), the LST ex-. Additional sealift capability is provided by two 4,300-ton, 100-metre support ships, KD Sri Indera Sakti (1503) and KD Mahawangsa (1504). Minehunting capabilities are provided by four s. These are Italian-built ships based on the Lerici-class but displacing 610 tons. Hydrographic duties are handled by KD Perantau and KD Mutiara. A Naval Air Wing was also founded with the purchase of ex-Royal Navy Westland Wasps. Some ships of the RMN that have been decommissioned was transferred to the Malaysian Maritime Enforcement Agency (MMEA). MMEA had received more than 20 vessels from the RMN fleet to equip its enforcement operations from 2000s onwards. Modernisation The modernisation of the RMN began in the late 1980s. Four s were purchased from Italy. These compact ships were originally built for Iraq, but were not delivered due to international sanctions put in place against Iraq. A prominent addition to the fleet were two s. Based on the Yarrow F2000 design, the two 2,300-ton frigates are armed with Exocet MM40 II SSM and the Sea Wolf VLS point defence SAM system with accommodation for one Westland Super Lynx helicopter.
