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.

Can reach and operate at higher altitudes than average aircraft of its time.
EXTENDED RANGE PERFORMANCE
Capability to travel considerable distances through onboard fuel stores.
Design covers the three all-important performance categories of speed, altitude, and range.
Ability to operate over ocean in addition to surviving the special rigors of the maritime environment.
Supports pressurization required at higher operating altitudes for crew survival.
Beyond a pilot, the aircraft takes advantage of additional crew specialized in specific functions aboard the aircraft.

monoplane / low-mounted / swept-back
Design utilizes a single primary wing mainplane; this represent the most popular mainplane arrangement.
Mainplanes are low-mounted along the sides of the fuselage.
The planform features wing sweep back along the leading edges of the mainplane, promoting higher operating speeds.
