The first foreign Navy to perceive the validity ofintermarine technology was the Royal Malaysian Navy. In 1981, well before the completion of the first "Lerici" built for the Italian Navy, they awarded intermarine a contract for four minehunters. Due to the specific operational and technical requirements of the Royal Malaysian Navy, the requested configuration was completely different from the one selected by the Italian Navy, although the hull concept was the same.
The four minehunters of the "Mahamiru Class" were delivered by the end of 1985. The length of these ships is 51 m., and the displacement is 540 t. The propulsion system is based on a concept similar to that of the Italian Navy, being implemented by two separate propulsion systems: For transit and normal navigation the ship is propelled by two diesel engines (made by MTU) driving two controllable pitch propellers, giving the ship a speed in excess of 16 knots. For precise navigation over the minefield the ship is propelled by two Riva Calzoni auxiliary thrusters, each driven by an electro - hydraulic motor, and can achieve a speed of 6 knots. Electric power is generated by three diesel generators, all of them located above the water line to minimise the magnetic signature and the underwater-irradiated noise. The Combat System consists mainly of a Thomson Command and Control system, a Thomson Sintra Hull Mounted Sonar (HMS) for mines discovery and classification, and two Mine Disposal Vehicles PAP 104 (supplied by ECA). The Communication system is made by TRT and the armament consists of a 40 mm. gun.
