Ying Ji-82 Anti-Ship Missile (C-802)
The Ying Ji-82 (C-802) anti-ship missile was derived from the YJ-8 (C-801) with extended range. The YJ-82 is externally similar to the YJ-8, and has the same solid-propellant rocket booster and guidance system as the YJ-8. The most distinctive difference on the YJ-82 is that it employs a turbojet with paraffin-based fuel to replace the original solid rocket engine. This caused the fuselage to be extended to accommodate the extra fuel. The max range of the missile has also been extended from the original 40 km (or 80 km for YJ-81/C-801A) to 120 km. The YJ-82 missile is carried by the latest Chinese-made surface combatants including the Type 051B (Luhai class) destroyer and Type 053H3 (Jiangwei class) frigate. Some ships built in earlier years have also been upgraded to carry YJ-82 missiles. Because of its extended range, the YJ-82 missile sometimes has to rely on airborne radar systems carried by helicopters or fixed-wing aircraft to provide target information. Iran reportedly bought about 60 land-launched variant YJ-82 missiles following the 1991 Gulf War. The air launched variant of the YJ-82 is designated YJ-82K (C-802K). A JH-7 fighter-bomber can carry four missiles. Some unconfirmed reports indicated that there is a 400 km-range land-attack cruise missile (LACM) variant of the YJ-82 fitted with GPS/TERCOM guidance. Although this has never been confirmed, it is certain that the YJ-82 missile does have the potential of being modified into LACM without too much difficulty. China has also developed the YJ-83 (C-803) anti-ship missile based on the YJ-82 design. Also powered by a turbojet engine, the YJ-83 is said to be supersonic and have an operational range of 250 km. A datalink antenna is fitted on the missile to receive midcourse target information from naval surveillance aircraft and helicopters. LAUNCH PLATFORM Land-based semi-mobile/mobile launcher Type 051B (Luhai class) DDG, Type 053H3 (Jiangwei-II class) FFG JH-7 fighter-bomber VARIANTS YJ-82 (C-802): Basic variant YJ-82K (C-802K): Air launched variant YJ-83 (C-803): Extended range supersonic variant DESIGN FEATURES The YJ-82 is almost identical to the Yj-8 in appearance apart from a slightly longer fuselage and an air inlet for the turbojet engine. The missile has a slim body and ovoid nose. There are four front delta wings, four smaller control surfaces, and four large tail stablising wings. The tail wings are mounted on the rocket booster and will be lost when the booster detaches from the missile body. The air inlet is located between the main fins under the missile body. The front and tail wings are folded when the missile is in the launcher. FLIGHT PROFILE When the missile is launched, the solid rocket propellant booster accelerate the speed of the missile from 0 to 0.9 Mach in few seconds. After the booster burns out, it detaches from the missile body and the missile's turbojet engine starts working. Controlled by the inertial autopilot system and radio altimeter, the missile flies at a cruising speed of 0.9 Mach and a flight altitude of 20-30 metres. When entering the terminal phase of flight, the missile switches on its terminal guidance radar to search for the target. Once locking on the target, the missile reduces its flight altitude to 5-7 metres at a distance of few kilometres away from the target. The missile may also maneuver during the terminal phase to make it a more difficult target for shipborne air defense systems. When approaching the target, the missile dives to hit the waterline of the ship to inflict maximum damage. GUIDANCE As well as its terminal guidance radar, the YJ-8 missile is also equipped with a radio altimeter for use with its autopilot during cruise. The missile's terminal guidance radar with monopulse system possesses high anti-jamming capabilities. The high precision radio altimeter allows the missile to have minimum-altitude flight above the sea, which is normally 20-30 m. WARHEAD The missile uses a 165 kg semi-armor-piercing anti-personnel blast warhead which relies on the missile's kinetic energy to pierce the deck of a ship, penetrate into and explode in the ship's interior. In addition, the YJ-82 might have a higher single hit ptobability than the YJ-8/YJ-81. SPECIFICATIONS Length: 6.392 m Diameter: 0.36 m Wingspan: 1.22 m (unfolded); 0.72 m (folded) Launch Weight: 715 kg Warhead: 165 kg time-delayed semi-armour-piercing high-explosive Propulsion: One turbojet engine, one solid booster Max Speed: Mach 0.9 Max Range: 120 km Flight Altitude: 20-30 m (flight); 5-7 m (attacking) Guidance Mode: Inertial and terminal active radar Single-Shot Hit Probability: N/A
