WASHINGTON / CANBERRA : The United States has formally delivered the first MC-55A Peregrine intelligence aircraft to the Royal Australian Air Force (RAAF), marking a significant milestone in Australia’s expansion of long-range intelligence, surveillance and electronic warfare (ISR/EW) capabilities amid rising strategic competition in the Indo-Pacific.
L3Harris Technologies confirmed on January 24, 2026, that the aircraft was handed over by the U.S. Air Force following completion of integration and mission-system testing. The transfer represents the first tangible outcome of Australia’s Peregrine program, a U.S. Foreign Military Sales (FMS) initiative designed to provide the RAAF with a highly survivable, multi-domain intelligence platform capable of operating in contested environments.
A New Strategic Intelligence Platform
The MC-55A Peregrine is a missionized, long-range aircraft designed to collect, process and disseminate intelligence across the air, land, sea, space and cyber domains. Built on a modified Gulfstream business jet airframe, the aircraft has been extensively reconfigured to support signals intelligence (SIGINT), electronic surveillance, electronic warfare (EW) and real-time data fusion missions.
Unlike traditional ISR aircraft focused on a single domain, the Peregrine is intended to function as an airborne intelligence node, linking sensors, shooters and command elements across the joint force. Australian defence officials view the platform as central to future long-range targeting, mission planning, and coalition operations, particularly across the vast distances of the Indo-Pacific.
L3Harris said the aircraft’s role extends beyond passive intelligence collection, enabling electronic support measures, threat detection, and real-time intelligence sharing with allied forces.
Delivery and Training Pathway
Under the delivery framework, the first MC-55A has been formally transferred from U.S. Air Force custody to the RAAF. Follow-on aircraft will remain in the United States for a defined period to support crew training, mission rehearsal, and pre-delivery activities. This phased approach is intended to accelerate Australian operational readiness while reducing transition risk for aircrew and maintainers.
L3Harris has also established an in-country field service team in Australia to provide technical support and integrate Australian industry partners into the sustainment chain. The company has committed to continuous software and hardware upgrades to ensure the aircraft remains effective against evolving electronic and cyber threats.
Capabilities and Mission Systems
While many of the MC-55A’s mission systems remain classified, available program details indicate the aircraft carries an advanced suite of SIGINT and electronic surveillance sensors capable of detecting, identifying and geolocating electronic emissions. These include radar systems, military communications networks, and other electromagnetic signatures associated with regional military activity.
The Peregrine’s open-architecture mission system allows onboard processing and rapid dissemination of intelligence to aircraft, naval vessels, ground forces and command centers. This enables near-real-time situational awareness and supports time-sensitive targeting decisions.
Designed for high-altitude, long-endurance operations, the MC-55A can operate at extended ranges, providing persistent coverage across large maritime and land theaters. Its business-jet heritage offers high transit speeds, allowing rapid repositioning between operational areas while sustaining extended on-station intelligence collection.
Specifications Overview
Based on the Gulfstream platform, the MC-55A Peregrine features a long-range airframe optimized for endurance, altitude and survivability. The aircraft is capable of operating at altitudes above 40,000 feet and has a range exceeding 6,000 nautical miles, depending on mission configuration. It is powered by twin turbofan engines and supports a multi-crew mission team, including pilots, mission operators and intelligence analysts.
The aircraft incorporates secure communications, encrypted data links, and interoperability standards compatible with U.S. and allied forces. Its modular mission architecture allows rapid upgrades as new sensors, processors and electronic warfare capabilities are introduced.
Strategic Significance
Australia’s acquisition of the MC-55A Peregrine reflects a broader shift toward high-end intelligence and electronic warfare capabilities as regional military activity intensifies. The aircraft is expected to replace and significantly expand legacy systems, delivering greater persistence, flexibility and survivability in contested battlespaces.
Interoperability with U.S. forces remains a core element of the program. Delivered through a U.S. Department of Defense–managed FMS framework, the Peregrine ensures common standards, shared logistics, and seamless integration during joint and coalition operations.
Jason Lambert, president of Intelligence, Surveillance and Reconnaissance, Space and Mission Systems at L3Harris, described the aircraft as a “force multiplier” for the RAAF, highlighting its role in delivering critical data for long-range targeting, regional deployments, and future Australian Defence Force operations.
As additional aircraft are delivered and brought into service, the MC-55A Peregrine is expected to become a cornerstone of Australia’s intelligence architecture, providing real-time situational awareness and electronic support across the Indo-Pacific at a time of growing strategic uncertainty.
