Australian Aircraft Carriers
The Canberra class of landing helicopter docks, based on the Spanish vessel Juan Carlos I, is composed of two ships. The class was built by Navantia and BAE Systems Australia; and HMAS Canberra are the largest ship ever built for the Royal Australian Navy.
Canberra underwent sea trials in late 2013 and was commissioned in 2014. Canberra‘s sister ship, HMAS Adelaide, was commissioned in December 2015. The Australian version retains the ski-ramp from the Juan Carlos I design, although the RAN has not acquired carrier-based fixed-wing aircraft.
