Russia has offered China a second batch of Sukhoi Su-35S Flanker multirole fighter aircraft destined for service in the People’s Liberation Army Air Force, TheDiplomat.com reported, quoting Russia’s Federal Service for Military-Technical Cooperation.

“We are expecting a response from China on our offer to purchase modern weapons and military equipment manufactured in Russia, including additional batches of Su-35 fighter jets,” the service said on the sidelines of the “Army-2019″ forum outside of Moscow. According to Chinese media reports, the PLAAF is considering the acquisition of additional Su-35 fighter aircraft.

The FSVTS confirmed in April that Russia completed the delivery of 24 Su-35s, the report said.

The first batch of four Su-35 fighter aircraft arrived at a flight training center of the PLAAF in Cangzhou City in Hebei province in northern China in December 2016. A second batch of 10 Su-35 fighter jets was delivered in December 2017.

China’s Ministry of National Defense officially confirmed in April 2018 that the Su-35 had entered service with the PLAAF. “The following month, PLAAF Su-35s for the first time escorted an undisclosed number of Xian H-6K bombers and support aircraft during a long-range patrol over the Bashi channel and around the island of Taiwan on May 11.”

China is the first international customer of the Su-35. Beijing and Moscow signed a US$2.5 billion contract for 24 aircraft in November 2015. Included in the sale is Russian ground support equipment and spare engines, the delivery of which is expected to be completed by 2020. The per-unit cost of a Su-35 is estimated at around US$85 million, the report said.

The PLAAF Su-35s can reportedly be armed with air-to-air and air-to-ground missiles, unguided rockets, guided bomb units and unguided bombs including the R-27 (AA-10 Alamo), R-73 (AA-11 Archer), RVV-family air-to-air missiles, as well as Kh-35E (AS-20 Kayak) anti-ship missiles.

Notably, the U.S. imposed sanctions on China for purchasing the Su-35s in breach of the congressionally mandated Countering America’s Adversaries Through Sanctions Act in September 2018.

The Sukhoi Su-35 Flanker is the top Russian air-superiority fighter in service today, the NationInterest.org reported, and represents the pinnacle of fourth-generation jet fighter design.

Distinguished by its unrivalled maneuverability, most of the Su-35’s electronics and weapons capabilities have caught up with those of Western equivalents, like the F-15 Eagle. But while it may be a deadly adversary to F-15s, Eurofighters and Rafales, the big question mark remains how effectively it can contend with fifth-generation stealth fighters such as the F-22 and F-35.

Capable of a maximum speed of Mach 2.25 (2,400 km/h), the Su-35S can supercruise at Mach 1.1+  (1,250 km/h) at medium altitudes and at sea level it can reach a speed of Mach 1.13 (1,400 km/h). The maximum range of the jet at altitude is 3,600 km (2,240 miles) while at sea level it is 1,580 km (980 miles) with a combat radius of around 1,600 km (932 miles).

The eyes of the Su-35S includes the Irbis-E (snow leopard) passive electronically scanned array (PESA) radar which can detect and track up to 30 aerial targets simultaneously up to 400 kilometres, and attack up to eight of them.
