from the rear hangar and flight deck. The Ka-28 is equipped with a search radar and dipping sonar and can also employ sonobuoys, torpedoes, depth charges, or mines. The Z-9 is a variant of the Airbus Helicopters AS365 Dauphin. The naval variant of the Z-9, the Z-9C, is equipped with the KLC-1 search radar, dipping sonar, and is typically armed with a single, lightweight torpedo. Either helicopter significantly improves the anti-submarine capabilities of the Type 052C. Propulsion The Type 052C propulsion is in the combined diesel or gas (CODOG) arrangement, with two Ukrainian DA80 gas turbines and two MTU 20V 956TB92 diesel engines. The DA80s had blade problems and may have contributed to the last two Type 052Cs sitting pierside at the shipyard for two years without being accepted by the PLAN. The MTU 20V 956TB92 engines were license-produced by Shaanxi Diesel Engine Works.
