A formation of C-130J Hercules transport aircraft will fly over Glenbrook on Friday, September 6.
The aircraft are due to fly over Glenbrook RAAF Base at 2.20pm as part of celebrations to mark their 20 years of service with the Royal Australian Air Force (RAAF).
Up to six RAAF C-130Js will appear in the formation, joined by a United States Air Force (USAF) MC-130J capturing imagery of the flight. Additional aircraft may join the formation depending on operational availability.
The aircraft will depart Richmond RAAF Base at 12.45pm and will fly over Barrenjoey Heads at 2pm before Glenbrook. They will return to Richmond at 2.25pm.
The flypast is subject to variables including weather, air traffic control, and operational availability, and may be subject to cancellation at short notice.
The C-130J variant of the Hercules transport aircraft was introduced to RAAF service in September 1999, joining a legacy of Australia operating different Hercules models since December 1958.
The C-130J has amassed 137,000 flying hours, and remains one of the busiest aircraft in the RAAF. They have supported numerous operations nationally and abroad, including deployments to the Middle East Region.
They are also extensively used for humanitarian assistance and disaster relief missions. This has included the Defence response to the 2004 Boxing Day Tsunami, the Bali Bombings, airdrops to Iraqi civilians, and the wake of numerous cyclones in Northern Australia and the South West Pacific.
