The American company Raytheon has started upgrading the old versions of deck fighters F/A-18 Hornet C and D belonging to the U.S. Marine corps. As writes Jane’s, as part of the ongoing work on the aircraft are installed a new radar station AN/APG-79(v)4 with an active phased antenna array (AFAR).
Radar with an active phased antenna array has a better performance compared with pulse-Doppler radars. Such stations currently are on the F/A-18C/D. Active phased array antenna works on the principle of phase control signals.
Due to the change in phase of the signals radiated by different receiving and transmitting modules, radar AFAR manage to form a powerful directional beam, and the direction of the beam can be changed. In the end, AESA radars are devoid of moving parts and therefore require less maintenance and provide rapid movement of the radar beam.
At the same radar with an active phased array capable of detecting airborne targets at much greater distance.
Through the modernization program will go through all the F/A-18C/D, standing on the arms of the US Marine corps. The military now have seven Hornet squadrons of 12 aircraft each. While the Marines have ordered the supply of a total of 112 radars, including spare copies. The upgrading work is scheduled for completion by may 2022.
In the middle of last year by order Raytheon aircraft manufacturing concern Boeing is engaged in the development of radar with an active phased antenna array for the strategic bombers B-52 Stratofortress. New development will be based on the radar APG-82 for fighter-bombers, F-15E Strike Eagle.
The new radar will allow the B-52 to make more accurate maps of the area, to detect more targets and to direct a greater number of found weapons purposes. Detection range of ground targets will also increase. The new radar will be able to work when executing both conventional and nuclear bombings.
