China Builds Its Own ‘Wild Weasel’ To Suppress Air Defenses

J-16D brings hammer down on SAMs

While China’s Anti-Access/Area Denial (A2/AD) operations rely on heavy air defenses, Chinese air force planners may also have to account for enemy surface to air missiles, all the more with Taiwan and Japan embarking on a new buildup of missile shields. In December, one of the responses was revealed: the Shenyang J-16D.

Wingtips

The J-16D’s wingtips have built in electronic intelligence pods, which intercept enemy electronic signals like radar transmissions, for processing in the fighter’s computers, which then tell the J-16D’s jammers how to scramble, confuse and block enemy usage of the electromagnetic spectrum.

The J-16D is a J-16/Su-30 multi-role fighter optimized for “Wild Weasel” missions. Starting in the Vietnam War, Wild Weasels are fighters designed to take on surface-to-air missile batteries in a SEAD (Supression of Enemy Air Defense) role. Armed with anti-radiation missiles (which lock on and target radars by their electronic emissions) and electronic intelligence and electronic warfare jammers, they are designed to engage and suppress defenses, opening the way for traditional air attacks.

Electronic Flanker

This comparision of the J-16D to the baseline J-16, done by noted aviation journalist Andreas Rupprecht, shows that the J-16D has removed its IRST sensor and 30mm cannon, as well as installing addition antennas.

Compared to the baseline J-16, the J-16D has removed its Infrared Search Tracking sensor and 30mm cannon to accommodate more electronics inside its fuselage. It also has several antennas mounted around its fuselage. The J-16D also two large ELINT pods on its wingtips, similar to those on the E/A-18 Growler, to collect enemy radar and electronic activity. Additionally, the J-16D has smaller radome, likely to include an active electronically scanned array (AESA) radar optimized for electronic warfare, including signals collection and jamming. The J-16D will be fitted with large AESA jamming pods, a development of current jammers on JH-7A attack aircraft; its attack ability will come from YJ-91, LD-10 and other anti-radiation missiles.

EW JH-7

The Xian JH-7 is China’s first generation twin seat strike fighter (a role now being taken over by the J-16). The JH-7 and JH-7A can carry two large electronic warfare jamming pods under their wings to jam enemy missiles and radar. The more capable J-16D will also carry such large pods (though upgraded with technology like AESA elements) as it flies alongside J-16 and other Chinese fighters.

The J-16D provides Chinese aerial operations with a fast, maneuverable and long range EW and Wild Weasel platform that can protect Chinese fighters and bombers like the J-10, J-11, J-15, J-20, J-31 and H-6K bomber. This will be an important requirement in combat operations in increasingly militarized areas like the Taiwan Straits and South China Seas. In combat operations, the J-16 would first use its jammers to disrupt the target and fire control of enemy air defenses, before firing its long range anti-radiation missiles, which are equally deadly against both mobile and fixed air defenses. As a fighter, it can still take part in aerial combat in self defense and to protect other aircraft against enemy fighters.

CM-102

The CM-102 anti-radiation missile, first seen here at the 2014 Zhuhai Air Show, is a supersonic, 100km range air launched missile with an anti-radiation warhead that homes in on the electronic activity of enemy transmitters like radars. The CM-102 is one of the many attack options for the J-16 to destroy enemy radars and other electronic equipment as part of its Wild Weasel mission.

China’s increasing ability to protect its power projection capabilities shows that its advances in military technology are just as much focused on taking action aboard to advance its interests, as opposed to the A2AD narrative of hunkering down against enemy threats. And, much as the US plans for F-35/22, Chinese Wild Weasel capabilities can be expected to migrate to fifth-generation stealth fighters, carrier aircraft, and drones large and small.
