Су-30МКPhazotron-NIIR Corporation and Sukhoi Design Bureau are bound by a long-term fruitful co-operation. The first fully independent development of the airborne radar under the name Oryol has been started in 1957 by OKB-339, (so the Phazotron was called at that time), under the leadership of G.M.Kunyavsky, former designer-in-chief. The Oryol radar was adopted for service with the Air Force as a part of the Su-11 fighter-interceptor airborne equipment. There followed new developments, such as ORYOL-D radar designed for the Su-15 aircraft, Typhoon and Typhoon-M, chief designer F.F.Volkov, for the Su-15TM and, finally, SUV-27 weapon control system (derivative of the N-001), chief designer V.K. Grishin, developed for the Su-27 aircraft.

The Su-27 aircraft with its outstanding design innovations has become one of the best fighters around the world and was purchased by many foreign countries. Excellent strength characteristics, phenomenal maneuverability, the capability, additionally to the above-mentioned functions, to carry a variety of diverse weapons and many other advanced technological achievements will allow the Su-27 and its modifications to confidently continue flying for many years to come.

However, global political and economic transformations in recent years changed the original designation of this splendid aircraft. It turned from the fighter-interceptor into the multipurpose combat aircraft, being capable, besides the above-mentioned missions, of carrying new ones, such as firing at ground and surface targets, including the application of up-to-date high-precision weapons, what has became one of the most important missions, especially, at waging current local wars, resolving conflicts as well as, when performing great anti-terror operations.

The Su-27 fighter actions on ground targets can be realized only with the working out and introducing a radar ground surveillance mode into the airborne radar and putting out the gained data in the form of a terrain surface area map on the display screen. Such a mode has obtained the name “mapping mode”. The operation in this mode enables the pilot to perform the following:

  • to bear in air space by means of the generated map without using outer aids (such as, satellite communication and so on);
  • to determine rational flight paths for entry on the target with continuous generation of a corrective channel to the aircraft navigation systems for target designation to the onboard weapon systems.

The increase of the number of functions carried out by the Su-27aircraft and its modification’s also has required a substantial improvement of onboard radar capabilities, ensuring the increase of the operational range, number of simultaneously tracked and attacked targets, nomenclature and quantity of radar-guided weapons, the target designation, permanent control and flight path correction of which are provided by the onboard radar.

The up-to-date radars developed by Phazotron-NIIR ensure the fulfilment of all the functions mentioned above, thereby, radars with Slot Array Antenna (SAA) provide for simultaneously detection of up to 10 targets and firing at 2-to 4 of them, while radars with Phased Array Antenna (PHAA) enable to detect up to 30 targets at a time and to fire at six of them, what allow to use successfully radars with PHAA in their new quality, namely, for protection of the aft hemisphere (or, how it is accepted to say “for tail protection”).

As a result, the following picture turns out in terms of the application of Phazotron-produced radars in by Sukhoi Design Bureau retrofitted and newly developed aircraft.

Su-25 TM (Su-39) upgrading

In field conditions, the Kopyo radar pod version (with SAA) may be mounted and introduced into the airborne aircraft equipment, quite quickly and at minimum aircraft rework as well as at minimum expenses. This provides the aircraft with new capabilities, such as all-weather day and night operation with carrying out all the above-indicated combat missions. The single drawback is a certain limitation on areas in air-to-air conditions due to the shadowing radars aspect angles by the aircraft nose section.

Target designation range in air-to-air mode is 57 km. Number of simultaneously tracked targets is 8, that of fired ones is 2.

The upgrading of the aircraft has been commenced in 1999. At present, the flight tests of the Su-25 TM aircraft upgraded with the airborne Kopyo Radar System are successfully being conducted.

When mounting the Kopyo-M radar into the fuselage nose section of the aircraft, all the above-described capabilities of the upgraded Su-25 are provided for without limitation of the radar air survey and with no decrease of the areas in air-to-air mode. Rework scope and cost of the aircraft upgrading in this case are somewhat higher. Besides, the aircraft acquires the capability of tracking ground moving over ground targets. It was achieved at the expenses of the availability of an improved computer in the Kopyo-M radar.

Target detection range increases by 1,5 factor and makes up 75 km. Number of simultaneously tracked targets accounts for 8, that of fired ones accounts for 2.

Su-27 and Su-33/Su-27KUB deck-based aircraft upgrading

The application of the Zhuk-M radar (with SAA) instead of the N-001 ensures the performing of all the above-indicated functions, including the operation on sea targets. The Zhuk-M system allows to detect targets at a range of 180 km, to track up to 10 targets and to engage two, simultaneously.

Su-30MK

The Application of the Sokol radar (with PHAA) ensures the execution of all above-mentioned functions. Sokol is capable to detect targets at a range of 180 km, to track up to 20 targets and to fire at 6, simultaneously.

New Developments of the Sukhoi Design Bureau

Phazotron-NIIR Corporation is offering its novelty for the up-to-date Sukhoi aircraft. This is an airborne defence and weapon control system, comprising the Sokol multifunctional forward hemisphere sighting radar (with PHAA), Pharaoh (with PHAA) for aft hemisphere protection and omnidirectional warning about a threat. Joint operation of radars ensures an efficient system for all-round defence.

It should be noted, that the unified system developed by Phazotron-NIIR Corporation, which includes baseline radars and a series of unified units to be used in them, allows the operational and maintenance costs to be drastically cut, including due to considerable decrease in spareparts demand.
