The Zhuk MSF/MSFE (above) is a passive ESA design intended to compete against the NIIP N011M BARS. It uses a Phazotron unique radial distribution arrangement in the backplane waveguide feed, and proprietary radiating element placement. The Zhuk MSFE has a .98 meter diameter aperture with 1662 radiating elements, and was developed for the Su-30MK3 Flanker G avionic suite intended for the PLA-AF (MAKS 2005).
The most advanced of the Phazotron Flanker radars is the Zhuk-MSFE PESA variant, currently being flight tested on the Su-27KUB/Su-33UB side-by-side cockpit navalised Flanker variant, likely to be acquired by the PLA-N as part of their intended carrier airwing for the Varyag CVA.
This radar is usually credited with a 2 KW average power rating and 8 kW peak power rating, putting it in the performance class of the NIIP N011 MSA radar on the Su-27K/Su-35 Flanker E. The PESA design has 1662 radiating elements.
