Due to Western sanctions, the Sukhoi Su-75 Checkmate fighter delays production

0

Rostec chief Sergey Chemezov informed during a meeting with Russian President Vladimir Putin on Tuesday (18) that the Su-75 Checkmate advanced fighter will start production in 2027 instead of starting in 2025, as previously planned.

The new deadline already takes into account the impacts of the sanctions that Russia is suffering due to its invasion of Ukraine, which has forced Rostec to redefine its priorities.

The nickname refers to the term “Checkmate”, the chess maneuver that ends the game leaving the king trapped. The prototype of the plane was unveiled in the middle of last year at the 2021 Moscow Air Show.

The fighter follows similar lines to the Su-57, Russia’s fifth-generation stealth aircraft. The fully movable vertical fins are V-shaped, the nose is very reminiscent of the Felon, but obviously, being single-engine, the air intake is totally different: at an acute angle, under the cockpit, and with a bulkhead along the centerline . Powertrain has yet to be revealed, but the engine is expected to feature thrust vectoring, with the nozzle shaft able to change up and down.

The Su-57 Checkmate has the nose landing gear offset to the left side of the aircraft and features a Flir at the front of the spherical cockpit, just like that of the Su-57. Also interesting are the trapezoidal wingtips, capable of carrying the latest sets of armaments.

In terms of performance, the aircraft is said to have a payload of 7.4 tonnes, a top speed of Mach 1.8 and a combat range of 1,700 kilometers without additional fuel tanks. It was also stated that the new plane is capable of maneuvering at 8g and flying at supersonic speeds.

The aircraft will also be able to operate UAVs (unmanned aerial vehicles) and will therefore be able to draw on the experience gained with the Su-57, which integrates with the S-70 Okhotnik-B UCAV (unmanned aerial vehicle).

As reported by our partner Aerointhe cost of flying the plane, according to Rostec, should be around 25 to 30 million dollars: little compared to the market segment in which it is positioned, which includes the Swedish Jas-39 Gripen, the Eurofighter Typhoon , the Dassault Rafale and Lockheed Martin’s F-35 Lightning II.

Checkmate is a product that has been designed to enable exports, in particular to African countries, India, South America and Vietnam, as Deputy Prime Minister Yuri Borisov has indicated, but should also equip the Russian Air Force itself, as experts in the field expect.
