HMAS Stalwart (A-304) at Melbourne, May 2022
The first known photo has surfaced of Australia’s newest intelligence, surveillance, reconnaissance, and electronic warfare aircraft, a highly modified version of the Gulfstream G550 business jet.

The aircraft, dubbed the MC-55A Peregrine by the Royal Australian Air Force (RAAF), was spotted flying from Gulfstream's plant in Savannah, Georgia.

The airframe, configured with what have been described as "airborne intelligence, surveillance, reconnaissance, and electronic warfare" (AISREW) mission systems, bristles with antennas and has a recognizable belly “canoe” that contains additional sensors. A distinct green colour on the aircraft fuselage shows that it is not complete or, at the very least, it is not yet painted in its final colour.

Notable features of Australia’s unique configuration seen in the photo include a dorsally mounted satellite communications antenna farm and a large satcom antenna fairing on the top of the vertical stabilizer. It features a bulbous tail cone housing very similar to what is seen on the CAEW, and what looks like an integrated electro-optical infrared (EO/IR) turret below the tail, although that could also be another dome with some sort of emitter inside. On the bottom of the jet, we see a tell-tale antenna farm that is used for electronic and communications intelligence-gathering and communications relay work.

Simply put, the RAAF is becoming one of the most capable air arms when it comes to dominating the RF realm.

Aside from the MC-55 aircraft, the RAAF has also fielded the EA-18G Growler electronic attack aircraft. When you add these two airframes to Australia's fleet of F/A-18 Super Hornets, F-35As — which are capable of electronic attack and electronic intelligence collection platforms in their own right — as well as P-8 Poseidons, MQ-4C Tritons, and future loyal wingman drones that can carry their own electronic warfare packages, the RAAF is clearly positioning itself as one of the most electronically aware and combat-capable air arms on the planet.
