The Spanish designed destroyers will be equipped with the Aegis combat system. It is smaller than US ships with this equipment. The Australian ships will use the locally developed radar antenna designed by CEA Technologies in Canberra.
The Landing Helicopter Dock Ships are planned to carry 1000 personnel, six helicopters and 150 vehicles, including the M1A1 Abrams tank. These will replace both HMAS Manoora and HMAS Kanimbla. There will also be new landing craft and communications for the ships. The ships are designed to be small aircraft carriers with a "ski jump" on the flight deck for the AV-8B Harrier II, and may be able to operate the F-35B Joint Strike Fighter. Australia has announced no plans for fixed wing aircraft on the ship, but UAVs could be operated.
