MC-55A Peregrine Signals Intelligence Aircraft

The MC-55A Peregrine is a modern signals intelligence aircraft designed for long range surveillance, electronic intelligence, and joint force support. Built to operate in contested environments, it provides real time intelligence across air, land, and maritime domains. The platform supports U.S. allied operations and reflects the growing demand for high endurance, sensor heavy ISR aircraft that can operate far from home bases.

Manufacturer

The MC-55A is produced by L3Harris Technologies, with the airframe based on the Gulfstream G550 business jet. While primarily operated by the Royal Australian Air Force, the aircraft uses U.S.-developed mission systems, sensors, and communications architecture. This makes it closely aligned with U.S. intelligence and interoperability standards.

Speed and Range

Powered by twin turbofan engines, the MC-55A offers high subsonic cruise speed and long endurance. It can operate at high altitude for extended periods, allowing wide area coverage and persistent intelligence collection. Its range enables missions across the Indo-Pacific without frequent refueling, a key advantage for long distance ISR operations.

Cost / Price

Exact unit cost figures are not publicly disclosed. Open source estimates place the program cost at several hundred million dollars per aircraft when mission systems, training, and support are included. The high cost reflects advanced electronic warfare systems, secure communications, and specialized intelligence payloads rather than the airframe itself.

The MC-55A does not carry weapons. Its value lies in collecting, processing, and sharing intelligence with allied forces in near real time. It plays a critical role in threat detection, battlespace awareness, and strategic decision making.
