The MC-55A Peregrine is part of Australia’s effort to strengthen ISR and EW capabilities with airborne electronic attack and SIGINT capabilities integrated on a Gulfstream G550 airframe.
The RAAF’s (Royal Australian Air Force) MC-55A Peregrine EW/SIGINT (Electronic Warfare/Signal Intelligence) appears to have commenced its second test flight campaign, as shown by the newly emerged photographs by aviation photographer @SR_Planespotter. Sharing the images on X, the photographer said the aircraft (tail number N540GA) arrived at L3Harris’ facility at Greenville in Texas “in its completed, fully modified state.”
