Have the Russians overtaken the Americans?
The spectrum of information received by the Sukhoi Design Bureau specialists during the recently completed unique stage of field tests of the promising multipurpose attack and reconnaissance UAV S-70 "Okhotnik" air and interception of priority air targets in those areas of theaters of war of the XXI century, where the abundance of modern air defense systems of a potential enemy (air defense systems "Patriot PAC-3MSE", SAMP-T, "Land Сeptor", etc.) calls into question the safety of the flight the operational-tactical aviation Russian Aerospace Forces.
The operational-tactical tandem "Su-57 ꟷ S-70" Okhotnik-B "makes another leap
We are talking about the successfully implemented "digital" (without actual launches and defeats) interception of heat-contrast and radio-contrast targets of a simulated enemy by means of short-range and medium-range training missiles UZR-73/74 and RVV-SD-UL (simulators R-73RMD-2 / RVV-MD and RVV-SD) deployed and virtually launched from the in-fuselage compartment of the S-70 “Okhotnik” UAV at the Ashuluk interspecific training ground in the Astrakhan region.
Despite the fact that the aforementioned flight training models of missiles did not "leave" the Okhotnik-B's in-fuselage hardpoints throughout the entire test period, the open architecture of the avionics in general and the weapons control system in particular (in conjunction with several asynchronous exchange lines data via secure radio communication channels and software and hardware diagnostic add-ons) provided Sukhoi Design Bureau specialists (as well as representatives of the Russian Aerospace Forces) with a host of critical parameters for synchronization and data exchange between Okhotnik-B weapons control systems and the Su-5 57th generation multifunctional fighter ... Su-57 acts as a leading component in this operational-tactical tandem. Obviously, the latter also took part in field tests.
Techno jump of Russia: journalists missed the sensation
RIA journalists Newsreferring to competent sources in PJSC "Company" Sukhoi "limited themselves to extremely superficial coverage of this event. Meanwhile, we are talking about a significant technological leap, embodied "in hardware" by the specialists of the Sukhoi Design Bureau.
In particular, the coordinates of the airborne AFAR-radar N036 "Belka" or the quantum optical-electronic sighting and navigation system OLS-50M of the Su-57 fighter aircraft detected in combat conditions can be transferred to the weapons control system (SUV) of the slave "Okhotnik-B" by means of a specialized "accompanying file" sent in encrypted (using the Reed-Solomon code) data packets by the on-board communication system S-111-N.
At the same time, having a much wider range (about 2900 km versus 2000 km for the Su-57), the S-70 Okhotnik-B strike and reconnaissance drone is capable of reaching the launch lines of the Product 180 long-range air combat missiles (or RVV-BD; correspond to the geometric parameters of the S-70 weapons compartments) along much more optimal and safe trajectories, bypassing the enemy's air defense systems in the terrain bend mode.
At the moment Okhotnik-B reaches the launch lines (continuously updated in the tracking file), the target coordinates will be instantly loaded into the drives of inertial navigation systems and active radar seeker of the Washer family of the Product 180 and / or RVV-BD missiles by means of a multiplex data exchange channel of the MIL-STD-1760 type (synchronizes the Okhotnik weapons control system with the avionics of interceptor missiles).
At the same time, the launch can be carried out in a covert mode (without using the Okhotnik airborne radar) and without the need to maintain line of sight between the C-70 and intercepted objects. In the latter case, we are talking about launching either from outside the radio horizon, or because of the "screen" of the terrain. This is true for remote targets operating in low altitude mode.
And the Americans are just scratching their heads
At the moment, hundreds of specialists from leading American military-industrial corporations are struggling to realize this potential within the ambitious NGAD (Next Generation Air Dominance) program. This project provides for the development and launch into large-scale production of the carrier-based stealth fighter F / A-XX in both manned and unmanned versions.
