"Eyes and ears" The core of the Su-35 armament is a new radar control system with a phased antenna array (Irbis-E). It features unique capabilities in terms of the target detection range. This is developed by V V Tikhomirov Research Institute of Instrument Production. In design, this is an X-waveband multi-role radar with a passive Phased Antenna Array (PAA) mounted on a two-step hydraulic drive unit (in azimuth and roll). The antenna device scans by an electronically controlled beam in azimuth and angle of elevation in sectors not smaller than 60°. The two-step electro-hydraulic drive unit additionally turns the antenna by mechanic means to 60° in azimuth and 120° in roll. Thus, in using the electronic control and mechanical additional turn of the antenna, the maximum deflection angle of the beam grows to 120°. Irbis-E radar control system detects and tracks up to 30 air targets, retaining continuity of space observation and engaging up to 8 targets. The system detects, chooses and tracks up to 4 ground targets in several map-making modes with various resolution at a range of up to 400 km, without stopping to monitor the airspace. Irbis-E radar detects air targets with an absolute cross section of 3 m2 on a head-on course at a range of up to 400 km. Being an improvement on radars with a PAA, Irbis has much better capabilities: expanded (by more than twice) operating frequency band, increased from 70о to 120о target detection and tracking zone in azimuth, substantially (by 2-2.5 times) increased effective range, improved anti-jamming capability, etc. In this aspect, Irbis is comparable to the best foreign counterparts, outperforming most of the US and European-made radars with passive and active PAA. The Research Institute has been developing Irbis since 2004. By now, the engineering prototypes of the system have passed the required bench trials. The first of them has been installed on the Su-30MK2 flying laboratory and is undergoing flight tests. The first flight of the flying laboratory with Irbis onboard occurred in early 2007 at Gromov Flight Test Institute. During the flight, the laboratory proved the superior performance of the new radar in the air-to-surface operating mode. Among other new onboard systems of the Su-35 is modern navigation and radio communication equipment, systems maintaining fighters operation in a formation and a highly efficient electronic countermeasures suite. The component package of the latter and its complementation with specific jamming devices can be determined by the customer. Armament In addition to the armaments onboard the modern Su-30MK, it is planned to additionally arm the Su-35 with new types of air-to-air and air-to-surface guided missiles, including long-range types. The maximum ordnance load of the Su-35 is 8,000 kg. This is placed in 12 weapon stations.
