HMAS Adelaide (L01) is the second of two Canberra-class landing helicopter dock (LHD) ships of the Royal Australian Navy (RAN). Construction of the ship started at Navantia's Spanish shipyard with steel-cutting in February 2010. The ship was laid down in February 2011, and launched on 4 July 2012. Delivery to Australia for fitting out at BAE Systems Australia's facilities in Victoria was scheduled for 2013, but did not occur until early 2014. Despite construction delays and predictions the ship was commissioned in December 2015.
