Fast Attack Craft FACG (Gun) and FACM (Missile) given the resolution of the satellite views of Malaysia, and the similarity of these craft, these identifications are a best guess. Some class units have landed their exocet missiles, making distinctions even more problematic. Most units have awnings fitted, which further obscure the deck structure.
Handalan Class Missile Boat LOA 143′ / 43.6 m TDISP 270 tons (4 active, service since 1978) variant of the Swedish Spica-M FAC. The below craft, whether they have missile armament on the quarterdeck or not, have the distinctive wider bridge front with more definition, as the bridge windows are down-angled, and are distinctively shorter missile armed FACs. They also have awnings fitted to the rear which protect the projecting wings behind the bridge.

Perdana Class Missile Boat LOA 154′ / 46.9 m TDISP 265 tons (4 active, service since 1972) German Lurssen design. Variant of La Combattante IIa class. Distinguished by its slightly longer hull, and a superstructure extending to the ship sides with an elevated deck running its full length on either side. [The below tweet mentions KD Perdana missing in 2017, but the boat and crew were later located safe]
Jerung Class gunboat LOA 147′ / 44.8 m TDISP 255 tons (6 active, service since 1976). Distinguished by the clean lines on its smaller deckhouse, and small awning.
