The latest Russian fifth-generation multi-functional fighter Su-57 has been equipped with two additional side antennas that complement the N036 Belka forward-looking radar complex.
N036 Belka is a multi-element dual-band complex operating on the basis of five active phased arrays (APAR) located in the nose of the fuselage and wing tips.
APAR consists of 1526 transceiver modules with an attenuator (a device for lowering electromagnetic oscillations) and a microwave transistor, capable of "forming dips in the radiation pattern in the direction of sources of radio-electronic interference from the enemy.
N036 Belka can simultaneously track 62 targets and issue target designations to R-77-1 missiles for 16 air targets in automatic mode.
Earlier www1.ru reported that RD-107/RD-108 engines for Soyuz rockets have reached a reliability rate of 99.9%.
