For the first time, the light tactical aircraft Checkmate was presented at the MAKS-2021 air show

MOSCOW, March 24. /TASS/. The Sukhoi company has obtained a patent for a new single-engine light tactical aircraft known as the Checkmate. The text of the patent (obtained by TASS), was published by the Federal Intellectual Property Service.

"The patent’s commencement date is 19.07.2021 and the date of registration, 23.03.2022. The field of invention is aviation, in particular, light tactical aircraft with low radar visibility," the document reads.

The Checkmate’s empennage is V-shaped. The air intake is located at the bottom of the fuselage. The patented layout increases the stability and controllability of the fighter plane without compromising radar visibility parameters.

For the first time, the light tactical aircraft Checkmate was presented at the MAKS-2021 air show. The fighter’s foreign presentation took place at the Dubai Airshow 2021 in the UAE. The Checkmate incorporates all most advanced technologies and ideas, including open architecture adjustable to customer requirements and unique artificial intelligence features. The new aircraft boasts low-visibility technologies and is equipped with an in-fuselage compartment for air-to-air and air-to-surface weapons. The payload exceeds seven tonnes. The fighter can hit up to six targets at once. The single-engine plane’s speed is Mach 1.8 and combat radius, 3,000 kilometers.

The Checkmate’s maiden flight is scheduled for 2023. Its serial production is due to begin in 2025.

Checkmate fighter’s designers took into account Lockheed F-117A’s weaknesses — patent​

The invention’s technical result was the achievement of the aircraft’s better stability and controllability without compromising radar invisibility characteristics, the document reads

MOSCOW, March 24. /TASS/. The developers of Russia’s cutting-edge single-engine Checkmate fighter took into account and corrected the weaknesses of the United States’ stealth aircraft Lockheed F-117A Nighthawk, as follows from the text of the patent (obtained by TASS), published by the Federal Intellectual Property Service.

The patent compares the Checkmate plane with its US counterpart Lockheed F-117A Nighthawk, which possesses low radar visibility features. "This aircraft has a number of disadvantages such as poor takeoff and landing characteristics, as well as insufficient stability and controllability in flight," the patent reads.

The Checkmate developers’ task was to eliminate the shortcomings of other known aircraft of this class.

"The invention’s technical result was the achievement of the aircraft’s better stability and controllability without compromising radar invisibility characteristics," the statement reads.\

Stealth planes’ profile​

The F-117 is a US single-seat subsonic tactical strike stealth aircraft from Lockheed Martin. It was intended for covert penetration through the enemy's air defense systems and attacks on strategically important ground targets. Its first flight was on June 18, 1981. A total of 64 planes were built. The last serial plane was delivered to the US Air Force in 1990. The plane participated in five armed conflicts. In 2008, all aircraft of this type were withdrawn from service for financial reasons. Its successor is the F-22 Raptor.

The F-117 owed its low visibility mainly to the specific angular shape of the hull composite and radar-absorbing materials and special coating.

The Checkmate plane, a product of the Sukhoi company (an affiliate of the United Aircraft Corporation Rostec) was for the first time presented at the MAKS-2021 air show. The fighter’s foreign presentation took place at the Dubai Airshow 2021 in the UAE. Its maiden flight is scheduled for 2023 and serial production is due to begin in 2025.

The Checkmate incorporates all most advanced technologies and ideas, including open architecture adjustable to customer requirements and unique artificial intelligence features. The new aircraft boasts low-visibility technologies and is equipped with an in-fuselage compartment for air-to-air and air-to-surface weapons. The payload exceeds seven tonnes. The fighter can hit up to six targets at once. The single-engine plane’s speed is Mach 1.8 and combat radius, 3,000 kilometers.

According to the patent, the Su-75 can be equipped with a vector jet nozzle that can be mounted on the fuselage’s axis of symmetry and utilised for flight control and trimming. The vector jet nozzle rotates in all directions except height, that is, up and down.

I like it.

On top of it - the Russians have become extremely good at PR too.

Their fighters aren't cheap anymore.

Back in the day there were design bureaus and manufacturers who were separate companies in the Soviet doctrine.

I don't know if that is true anymore.

The F-117 while still relevant today a LOW RCS platform isn’t what you want as a model for a much more maneuverable supersonic aircraft meant to be used in multirole profiles.

Sukhoi Patents Checkmate’s Unique Aerodynamic Design​

The patent confirms that the Russian-design aircraft is superior to known foreign analogues in terms of both flight and field performance. In addition, Russian designers have improved the Checkmate’s stability and control while maintaining its high aerodynamic performance and stealth characteristics.

Looks like a Klingon ship of war.

I like the Klingons a great deal, but they're muscle heads and don't have the superior thinking of the Romulans who have similar tech but are far more better at war.

 

[CAPRICORN-88]

Yes. Sukhoi should have patented right their products then anyone who copied them can be sued.

It is not to late now.

 

[Sinnerman108]

This is one project PAF should have considered in my opinion.

maybe now that time is right ...
