ROCS Tuo Chiang (618)

2014 MODERN NAVY

History

A relatively new type of corvette in service with the Republic of China (Taiwan) Navy is the Tuojiang class. Altogether, the twelve ships were designed with stealth-centric features that help limit radar signals by reducing overhangs on board and breaks in the ship's cleaning lines. By 2017, one ship the lead ship Takue had been completed, and 11 more were planned.

Tojan remains active in the ROCN fleet??.

The Tuojiang River is the culmination of the government's "Xunhai" program to improve naval capabilities in and around Taiwan waters. The plan was announced in 2010, and the budget was approved the following year. A model was released in 2013, and the main ship (and class) name was announced in March 2014.

Construction of the vessel began in 2012.

The battleship had a displacement of 567 tons at full load, an overall length of 198 feet, a beam of 46 feet, and a draft of 7.5 feet. The shallow draft allows the frigate to operate along the coast of Taiwan and penetrate deep water. Power comes from an MTU 20V 4000 M93L marine diesel engine rated at 5,766 hp. This is combined with 4 MJP CSU 850 series water spray nozzles for precise manipulation.

The top speed in ideal conditions is 40 knots, which makes the Tuo Chiang very fast for her size and displacement.

The main design feature of the Tuo Chiang is the catamaran's hull layout, which helps provide the vessel with the necessary "fast" speed and promotes generally good seaworthiness in rough waters. The vessel is designed to operate in sea conditions up to class 7 (high wave action, class 9 is the absolute highest).

41 people on board, as well as advanced processing systems and sensors. Surface search is guided by CS/SPG-6N(S) series radars and fire control is guided by CS/SPG-6N(T) radars. Depth sonar can be used to hunt submarines.

Electronic warfare is handled by a 12-counter IR/RF chaff dispenser kit, six of which are mounted in the bow and the remaining six in the stern - providing the Tojang with strong cover against incoming enemy missiles.

The armament makes the Tuojiang a "multi-mission" ship capable of performing various tasks other than patrolling. Equipped with 8 Xiongfeng III series anti-ship missiles and 8 Xiongfeng II series anti-ship missiles. More conventional armament is provided by the 76mm OTO-Breda deck gun with the turret located above the forecastle. Carry a 20mm phalanx weapon system for close range defense against incoming air threats. Carry 2 12.7mm Browning M2HB machine guns for close range defense against oncoming fast attack ships.

In addition, Tuo Chiang will receive 2 x Mark 32 triple torpedo tubes, one on port and one on starboard.

Above the stern is a helideck suitable for launching and recovering a medium lift transport helicopter for resupply at sea.

The shape of the Tuo Chiang is that of a futuristic sea vessel with flat, uncontoured sides and a full deck line. The fuselage superstructure sides are integrated into the actual fuselage sides. The bow was intentionally designed to be relatively featureless, with minimal protruding (except for turret deck guns).

The bridge structure is formed as part of the hull superstructure and the overhead main mast set is largely enclosed.
