The Zvezda Kh-35U ('Star', Russian: ?-35?, AS-20 'Kayak') is the jet-launched version of a Russian subsonic cruise anti-ship missile. The same missile can also be launched from helicopters, surface ships and coastal defence batteries with the help of a rocket booster, in which case it is known as Uran ('Uranus', SS-N-25 'Switchblade', GRAU 3M24) or Bal ('Ball', SSC-6 'Sennight', GRAU 3K60). It is also nicknamed "Harpoonski", because it looks like and functions very similar to the American Harpoon anti-ship missile. It is designed to attack vessels up to 5,000 tonnes.

Development
Zvezda started work on the Kh-35 in 1983 by a decree of the USSR Council of Ministers and the USSR CPSU Central Committee to arm ships of medium tonnage.

Design
The Kh-35 missile is a subsonic weapon featuring a normal aerodynamic configuration with cruciform wings and fins and a semisubmerged air duct intake. The propulsion unit is a turbofan engine. The missile is guided to its target at the final leg of the trajectory by commands fed from the active radar homing head and the radio altimeter.
Target designation data can be introduced into the missile from the launch aircraft or ship or external sources. Flight mission data is inserted into the missile control system after input of target coordinates. An inertial system controls the missile in flight, stabilizes it at an assigned altitude and brings it to a target location area. At a certain target range, the homing head is switched on to search for, lock on and track the target. The inertial control system then turns the missile toward the target and changes its flight altitude to an extremely low one. At this altitude, the missile continues the process of homing by the data fed from the homing head and the inertial control system until a hit is obtained.
The Kh-35 can be employed in fair and adverse weather conditions at sea states up to 5-6, by day and night, under enemy fire and electronic countermeasures. Its aerodynamic configuration is optimized for high subsonic-speed sea-skimming flight to ensure stealthy characteristics of the missile. The missile has low signatures thanks to its small dimensions, sea-skimming capability and a special guidance algorithm ensuring highly secure operational modes of the active radar seeker.
Its ARGS-35E active radar seeker operates in both single and multiple missile launch modes, acquiring and locking on targets at a maximum range of up to 20 km. A new radar seeker, Gran-KE has been developed by SPE Radar MMS and will be replacing the existing ARGS-35E X band seeker.
Operational history
The Kh-35 missile entered service in 2003. In July 2003, the system created by the "Tactical Missiles Corporation" successfully passed the state tests and began to come into service of ships of the Russian Navy. Today it is generally accepted that in the criterion of "cost-effectiveness", "Uran-E" is one of the best systems in the world. It has also been acquired by India. The Bal coastal missile system in the fall of 2004 showed excellent results in the state tests and entered service in 2008. A Bal system has four self-propelled launcher vehicles each carrying eight missiles for a total of 32 missiles in a salvo, plus reloads for another wave. The launchers can be up to 10 km from the coast and hit targets at ranges up to 120 km (75 mi; 65 nmi). In 2015, plans were announced to equip the Bal system with an upgraded version of the Kh-35E to increase range to 300 km (190 mi; 160 nmi). From 2001-2015, Russia supplied Vietnam with 198 Kh-35E missiles for sea-based use. By June 2016, Vietnam was planning to start serial production of their indigenous KCT-15 anti-ship missile based on the Kh-35E, covering three types of Kh-35E missiles for sea-launched, air-launched, and coastal defense as part of the 3K60 Bal/SSC-6 Sennight mobile coastal defense system.
