054A fully indigenous? ....
Main gun >> cloned russian AK 176
ASW torps >> acoustic-homing torpedo , possibly developed from the Yu-7 (= US Mk-46 copy).
SAM >> exact model of the air defence missile is unknown, but some reports have suggested that it may be the 38km-range Russian 9M317 (NATO codename: SA-N-12) Shtil semi-active radar-homing medium-range SAM, or its Chinese copy reportedly designated HongQi-16 (HQ-16).
RADARS:
>> The air search radar is a russian Fregat-MAE-5 (NATO reporting name: Top Plate) 3D air search radar
>> Four russian MR90 (NATO reporting name: Front Dome) F-band radars (two on top of the bridge, two on the roof of the helicopter hanger) provide guidance for the air defence missiles. Originally designed to provide fire-control for the 9M317/SA-N-7 Shtil SAM
>> A large round radome installed on top of the bridge houses the russian Mineral-ME (NATO reporting name: Band Stand) radar that provides anti-ship missile control and over-the-horizon radar acquisition and target designation of surface ships.
>> The Type 054A is reportedly fitted with a Russian MGK-335 fixed sonar suite, including Bull Horn active and Whale Tongue passive hull-mounted, medium frequency search and attack sonar.
>> The propulsion is a combined diesel and diesel (CODAD) arrangement. The system is based on four SEMT Pielstick (now MAN Diesel SA) 16 PA6V-280 STC diesel engines, one of the most advanced diesel engine designs in Europe. China imported the 16 PA6V-280 STC diesel technology in the late 1990s and is now producing the diesel locally under license at Shaanxi Diesel Factory
