Final Operational Capability (FOC) has been declared for the block upgrade of Australia’s C-130J Hercules fleet. The fleet of 12 aircraft are operated by No. 37 Squadron, based at RAAF Base Richmond, NSW. Delivered under Project AIR 5440, the upgrades to aircraft systems and safety-critical software and hardware bring the C-130J Hercules fleet up to the latest Block configuration (Block 8.1), enhancing capability, reliability, and mission readiness.
Additionally, the aircraft have received significant upgrades to their communications and navigation suite; incorporating datalink, integrated satellite voice, new high-frequency radios, and improved instrument approach capabilities.
The first aircraft was upgraded by Lockheed Martin in the United States with support from the United States Air Force. The remaining 11 aircraft were modified at RAAF Base Richmond by C-130J sustainment partner Airbus Australia Pacific. The C-130J Full Flight Simulator has also been upgraded, with system modifications completed by CAE Australia.
The C-130J Hercules was introduced to Australian service in 1999. Capable of moving approximately 120 passengers or up to 20 tonnes of cargo, the aircraft provides a medium air mobility capability for the Australian Defence Force between the smaller C-27J Spartan and larger C-17A Globemaster III. The Block 8.1 upgrades will ensure the aircraft remain at the forefront of capability until deliveries of Australia’s expanded replacement fleet of 20 new C-130J Hercules aircraft begin later this decade.
“The completion of the Block 8.1.1 upgrade for the RAAF’s C-130J fleet is a significant milestone for Lockheed Martin and our partners in Australia,” said Trish Pagan, vice president and general manager, Air Mobility and Maritime Missions, Lockheed Martin. “This upgrade ensures the RAAF’s C-130J fleet remains at the forefront of tactical airlift capabilities, providing critical support for Australia’s military operations and humanitarian missions well into the future.”
“Delivering 11 of 12 Block 8.1.1 upgrades here in Australia is a clear demonstration of the deep and highly sophisticated C-130J sustainment capability we have established with our industry partners locally,” said Nicole Davidson, C-130J program manager, Lockheed Martin Australia. “This achievement reflects the strength of our industry partnerships and showcases the value of a sovereign industrial base that can deliver advanced capability upgrades for the Royal Australian Air Force’s C-130J fleet.”
As a member of the C-130J Super Hercules Joint User Group (JUG), Australia plays a key role in shaping and developing the Super Hercules Block Upgrade Program. The JUG drives the ongoing Block Upgrade program and ensures that the C-130J remains a highly capable and reliable tactical airlifter. The Block 8.1 software has been adopted by a growing number of operators, including the U.S. Air Force, Marine Corps, and Coast Guard, Norway, France, Germany and New Zealand.
The RAAF’s commitment to the C-130J program extends beyond operations, with Australia-based suppliers contributing to the aircraft’s production and sustainment. In 2023, Australia formally acquired 20 new C-130J Hercules aircraft to replace and expand its existing fleet, with deliveries expected to begin in late 2027.
