Authored By: Staff Writer | Last Edited: 05/14/2021 | Content ©www.MilitaryFactory.com | The following text is exclusive to this site.
The MC-55A ?Peregrine? is a Royal Australian Air Force (RAAF) SIGINT (SIGnals INTelligence) and ELINT (ELectronic INTelligence) special-mission aircraft built atop the framework of the Gulfstream G550 twin business jet. The versatile G550 is a proven performer, having been taken into service at various government, civilian, and military market levels.

In the latter part of 2015, the RAAF put in an order for two G550 aircraft (with an expanded interest for five) for Peregrine SIGINT/ELINT conversion. The work is handled by the United States with delivery to be had through RAAF Base Edinburgh. The move coincides with the modernization of the Aegis defense system featured in the Royal Australian Navy?s (RAN) Hobart-class Air Warfare Destroyer (AWD). The MC-55A will be used in the long-range maritime Intelligence-Surveillance-Reconnaissance (ISR) role as well as Electronic Warfare (EW) and retains all of the capabilities inherent in the G550 bizjet.
