The China Shipbuilding Trading Corporation (CSSC) has revealed a new trimaran-hulled frigate concept at the IDEX show held in Abu Dhabi, telling Jane's that a version was being built for China's People's Liberation Army Navy (PLAN).

The specifications provided by CSSC for the trimaran vessel state that it displaces 2,450 tonnes, has a length of 142 m, a width of 32.6 m, a cruising speed of 25 kt, and an endurance of 30 days. A CSSC official added that its top speed is between 30-35 kt and that it has a crew of more than 100.
CSSC officials said the vessel uses diesel engines that power a "marine electric propulsion system" that in turn drive three pump jets. It does not have a secondary propeller propulsion system.
Although lighter than China's Type 054A frigate, the trimaran carries a similar armament of one 76 mm main gun, vertical launch tubes for 16 or 32 missiles, eight anti-ship missile launchers, two close-in weapon systems, and hangar space for two helicopters.
