Chinese state-owned shipbuilder China Shipbuilding and Offshore International Company (CSOC) revealed technical specifications of a new frigate design it is showcasing at the LIMA 2017 exhibition in Langkawi.

In an interview with Jane's, a CSOC engineer disclosed that the "new ship is a derivative of the Jiangkai II class of frigates, but features a renewed superstructure".

According to specifications confirmed by the company, the vessel is slightly larger than the Jiangkai II, featuring an overall length of 135 m, a beam of 16 m, a draught of 4.4 m, and a displacement of around 3,850 tonne.

The platform is powered by four sets of 16PA6STC engines in a CODAD configuration, driving two propeller shafts for a top speed of up to 26 kt. It has an endurance of 21 days, and standard range of 4,000 nautical miles at cruising speed of 18 kt.

Where the innovation stands, however, is in the armament suite and sensors. Weapons aboard comprise a single-barrel 76 mm main naval guns, topped up by two six-barrel Type 730A 30 mm guns for short-range self defence.

"Unlike in other versions [of frigates displayed by CSOC at defence shows], the two 30 mm guns are no longer mounted on the main bridge, but rather amid-ship, closer to the [24-cells] surface-to-air missile [SAM] launcher."

The ship's foredeck still hosts a 32-cell vertical launching system (VLS) firing the HHQ-16 (40 km of range), and there are two quadruple launchers of the C-802 surface-to-surface missile (SSM) mounted amid-ship.

Commenting on the sensors, the engineer added that "the above-water sensor suite will include a phased-array radar mounted in an integrated mast. The ship will also mount an over the horizon [OTH] radar comparable to the [active/passive] SLR66".

The frigate's anti-submarine warfare (ASW) capabilities will be provided by a hull-mounted sonar and torpedo tubes.
