The projection ship ordered by Turkey will based on the Spain LHD ship Juan Carlos 1 (built by the Spanish shipyard Navantia) which also serve as the base of 2 futurs Australian Canberra-class landing helicopter dock (LHD) HMAS Canberra and HMAS Adelaide.
In 2004, French company Direction des Constructions Navales (DCN) and Spanish company Navantia were invited to tender proposals, with DCN offering the Mistral-class amphibious assault ship and Navantia proposing the "Buque de Proyección Estratégica" design (later commissioned as Juan Carlos I). The Spanish design was selected in 2007, with Navantia responsible for construction of the ships from the keel to the flight deck, and BAE Systems Australia handling the fabrication of the superstructure and fitting out.
The construction of the first ship, HMAS Canberra, commenced in late 2008, with the hull launched in early 2011, and sea trials in early 2014. Canberra was commissioned in November 2014. Work on the second vessel, HMAS Adelaide, started in early 2010. Adelaide is predicted to enter service in 2016. They are the largest vessels ever operated by the RAN, with a displacement of 27,500 tonnes (27,100 long tons; 30,300 short tons).
The French Mistral class (BPC = projection and command ship) is an Amphibious general assault ship (LHA) that means an Amphibious general assault ship with flush deck and dock for amphibious craft. Tarawa Class ships (US Navy) are an other example. The Spanish Amphibious Assault-Ship, Multi-purpose (LHD) Juan Carlos 1 is identical to the LHA but with a capacity to lead maritime space control operations and force projection missions using ASW helicopters and V/STOL aircraft. Other examples of these type are the Wasp (US Navy).
This Turkish decision is a bad news for the French shipyard DCNS unable the deliver Sevastopol and Vladivostok Mistral class BPC ordered by Russia, due to political reason (EU embargo) and after the loss of the Australian tender France can lost the confidence of others futur potential customers.
