On 16 January 2025, a future Royal Australian Air Force (RAAF) Gulfstream MC-55A Peregrine, bearing test registration N540GA (5540), began a second series of test flights from the L3Harris facility in Greenville/Majors (TX).

The aircraft, part of Australia's new airborne ISREW (Intelligence, Surveillance, Reconnaissance, and Electronic Warfare) capability, displayed full RAAF-markings, including the unit insignia of No. 10 Squadron, featuring the motto 'Strike First'. The RAAF serials for these aircraft will start with A51-, most likely ranging from A51-001 to A51-004.

In March 2019, Australian Defence Minister Christopher Pyne and Minister for Defence Industry Linda Reynolds announced a USD1,6 billion acquisition of four modified Gulfstream G550 aircraft. These are designated as MC-55A Peregrine and form part of Project AIR 555.

L3 Technologies (now L3Harris) was awarded a contract valued at over USD628 million to deliver these aircraft with next-generation airborne electronic warfare capabilities. The modifications include airframe enhancements, installation of mission systems, secure communications equipment, and self-protection suites. The modifications are being performed at L3's facility in Greenville (TX) and at Gulfstream's facility in Savannah (GA).
