The aircraft is designed for covert penetration through enemy air defense systems, as well as strikes against strategically important ground targets. The F-117 is a US single-seat subsonic tactical attack stealth aircraft from Lockheed Martin. "The technical result of this invention is the achievement of greater stability and controllability of the aircraft, without compromising the invisible characteristics of the radar," the statement continued. The task of the Checkmate developers was to eliminate the shortcomings of other known aircraft of this class. "This aircraft had a number of drawbacks such as poor takeoff and landing characteristics, as well as inadequate stability and controllability in flight," the patent reads. The patent compares the Checkmate aircraft to its US counterpart the Lockheed F-117A Nighthawk, which features low radar visibility. Interestingly, the developers of Russia's state-of-the-art single-engine Checkmate fighter took into account and corrected the weaknesses of the United States' Lockheed F-117A Nighthawk stealth aircraft, according to the patent text published by the Federal Intellectual Property Service. "We borrowed onboard equipment and engines from the fifth-generation fighter Sukhoi-57, but reconfigureed it a bit," Chemezov said, adding that Rostec built the plane with its own money without using budget funds. He explained that so far a prototype has been made and designer documentation is being developed.

"We have plans to start serial production in 2027," he said, launching TASS May 18 Serial production will begin in 2027, Rostec company CEO Sergey Chemezov said at a meeting with President Vladimir Putin on Wednesday.
