replacements, the and FREMM frigates. In late 2011, the French Navy selected the NARWHAL20 remote weapon station (RWS) to equip Mistral ships for close-in self-defense. Nexter Systems will deliver two NARWHAL20B guns for each ship, chambered in 20×139mm ammunition, with one gun covering the port bow and the other covering the starboard stern. Dixmude was the first of the vessels outfitted with the cannons in March 2016. In late 2013, the French Navy equipped all three Mistrals with two M134 Miniguns each; intended for close-in self-defence against asymmetric threats faced during anti-piracy operations, such as speedboats and suicide boats. In December 2014, the French Navy awarded a contract to Airbus to study the integration of the Multiple Launch Rocket System (MLRS) on Mistrals. This is to increase the ships' naval fire support capabilities, as 76 mm and 100 mm guns have been determined to have insufficient range and lethality. The MLRS is in French Army service, using a GPS-guided rocket with a range of and a unitary high-explosive warhead. Hospital Each ship carries a NATO Role 3 medical facility, i.e., equivalent to the field hospital of an Army division or army corps, or to the hospital of a 25,000-inhabitant city, complete with dentistry, diagnostics, specialist surgical and medical capabilities, food hygiene and psychological capabilities. A Syracuse-based telemedicine system allows complex specialised surgery to be performed. The hospital provides 20 rooms and 69 hospitalisation beds, of which 7 are fit for intensive care. The two surgery blocks come complete with a radiology room providing digital radiography and ultrasonography, and that can be fitted with a mobile CT scanner. 50 medicalised beds are kept in reserve and can be installed in a helicopter hangar to extend the capacity of the hospital in case of emergency. Propulsion The Mistral class are the first ships of the French Navy to use azimuth thrusters. The thrusters are powered by electricity from five 16-cylinder Wärtsilä 16V32 diesel alternators, and can be oriented in any angle. This propulsion technology gives the ships significant manoeuvering capabilities, as well as freeing up space normally reserved for propeller shafts. The long-term reliability of azimuth thrusters in military use is yet to be rigorously studied, but the technology has been employed aboard ships in several navies, including the Dutch , the Spanish , and the Canadian . Accommodation The space gained by the use of the azimuth thrusters allowed for the
