The construction of the Luzhou class destroyer at China’s northern Dalian Shipyard was revealed in 2004 with the help of Internet photographs. A disadvantage of the Type 051C is that it lacks the stealthier radar cross-section found on the newer Chinese warships. The ship also possesses less advanced steam turbine propulsion compared to gas turbine propulsion present in all newer Chinese destroyers. The Type 051C is a stop gap measure to provide long range area air defense to the fleet by mating the mature hull design with proven SAM system that is more capable than that of Type 052B destroyer. Production of this class stopped once more advanced Type 052C destroyers became available.
Missiles
The Luzhou class uses the advanced Russian S-300FM air defence missile system with track-via-missile homing guided by a single Tombstone radar. The missile has a maximum range of 150 km and an operating altitude of 10 m - 27 km. The anti-ship abilities possessed by the Luzhou class includes 8 indigenous YJ-83 Anti-ship missiles. This anti-ship missile has a range of 150+ km and approaches its target in sea skimming mode at a speed of Mach 1.5. As a secondary role, the missile can also be used against land targets.
Guns
The ship uses two Type 730 CIWS guns for air defence. The Type 730 is a highly effective CIWS that is also installed on the Type 052B and Type 052C/052D destroyers, and the Type 054A frigates. The ship also has 100 mm gun based on a French design for use against surface targets.
Sensors
The S-300FM missile is guided by the Volna 3D phased-array target tracking radar installed on top of the stern deckhouse. The radar can direct 12 missiles to engage 6 targets simultaneously. Since two radars are required to give 360° coverage, this means that there is a blind gap on Type 051C in full SAM cover in the forward quadrant, resulting in a major tactical restriction. The air search radar is a Fregat-MAE-5 3D air search radar mounted at the top of the rear mast, offering two channels in E-band. The radar can track up to 40 targets simultaneously, and has a maximum range of 120 nmi to aircraft and 20 nmi to sea-skimming missile. There is also a large round radome mounted at the top of the front mast, housing a Type 364surface search radar. A large round radome installed on top of the bridge houses the Mineral-ME radar that provides anti-ship missile control and over-the-horizon radar acquisition and target designation of surface ships. There are two indigenous Type 347G I-band radars integrated with the Type 730 CIWS to provide fire-control.
Propulsion
The ships are powered by two indigenous steam turbine engines giving them a top speed of 30 knots.
