Australia has decided to retire its fleet of Leonardo C-27J Spartan military transport aircraft and replace them with commercial airframes under the country’s updated defense strategy.
Announced in April, the decision forms part of a broader restructuring of the Royal Australian Air Force focused on enhancing long-range strike and surveillance capabilities.
Canberra has yet to announce a timeline for the retirement or identify the commercial aircraft that will replace the Spartans, according to local reports.
The future commercial fleet is expected to support “sovereign airlift and surveillance needs of Pacific partners,” while the Royal Australian Air Force’s incoming fleet of 20 new C-130J Hercules aircraft will handle more demanding military transport missions.
Sources indicated that the retirement decision was influenced by sustainment and modernization difficulties, including shortages of spare parts and complications linked to the aircraft’s specialized Australian configuration.
Reports also pointed to challenges integrating updated identification friend or foe (IFF) systems into the platform.
Despite these issues, the C-27J Spartan has played an important role in domestic disaster-relief operations, including recent bushfire and flood response missions in Queensland.
Its short takeoff and landing capability also allowed it to operate from remote airstrips, making it valuable for Pacific regional deployments and humanitarian support operations.
The C-27J Spartan
Australia inducted the C-27J Spartan in 2015 as a tactical battlefield airlifter capable of operating from short and austere runways.
In 2020, the aircraft was reassigned from frontline combat support roles to light transport and humanitarian assistance missions.
Australia currently operates a fleet of 10 Spartans through No. 35 Squadron based at Amberley in Queensland.
The aircraft measures 23 meters (75 feet) in length, has a wingspan of 29 meters (95 feet), and can carry up to 11,300 kilograms (24,912 pounds) of cargo or up to 60 troops.
It is powered by two Rolls-Royce AE 2100D2A turboprop engines generating over 4,600 horsepower each, paired with six-blade Dowty propellers measuring 14 feet in diameter.
Operationally, the C-27J can achieve a maximum speed of 325 knots (602 km/h or 374 mph), a range of 950 nautical miles (1,759 kilometers), and a service ceiling of 30,000 feet (9,144 meters).
