What is known about the first prototype of the Su-75 Checkmate after new photos

The first experimental prototype of the single-engine light fifth-generation Su-75 Checkmate fighter was captured at one of the airbases of the Russian Aerospace Forces (VKS). Military expert Evgeny Damantsev spoke about the main advantages of the new combat vehicle.

He drew attention to the fact that, based on a visual comparison with photographs taken in November 2021, it can be concluded that this is the same instance - the camouflage elements match.

Operates autonomously

The specialist recalled that in the "5++" generation version, the machine should be able to operate autonomously - using its own inertial navigation system and on-board central computer.

The fighter received complex source code algorithms for conducting air combat, overcoming air defense systems (air defense) and attacking surface targets - in fact, with elements of artificial intelligence.

At the same time, there is the possibility of network operation: the Su-75, in the role of an unmanned slave, will be connected to the Su-57 multi-functional fighters via a secure channel of a two-way asynchronous data exchange line, where the terminal on the Su-57 will act as a combat control point.

Only one engine - less visibility

As a power plant, options are being considered for one engine: "Product 117C" (AL-41F1S) with an afterburner thrust of 14,500 kgf, AL-41F1 - 15,000 kgf, or "Product 30" with a thrust of up to 18 kg.

Power plants will provide a calculated thrust-to-weight ratio in the range of approximately 0.9-1.25 kgf/kg, depending on the combat load and fuel mass, as well as low visibility to radars.

Will accelerate to 1.6 M

For radar stations (radars) on the Su-75, the detection range of targets with an RCS of 1 m² is indicated at the level of 180-200 km. Standard multi-spectral optoelectronic sighting systems of the OLS-50M line will allow you to detect any heat-contrast and optical-contrast targets.

The estimated practical ceiling of the Su-75 is estimated in the range of 16,500-17,500 m. Cruising supersonic speed is 1.6 M, maximum is up to 2.1-2.2 M.

Earlier www1.ru reported that Russian Buk-M2E anti-aircraft air defense systems were deployed in Venezuela.
