MU90 Impact
Template:Infobox weapon The MU90 Impact is a Franco-Italian advanced lightweight anti-submarine torpedo of the third generation<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> developed for the French and Italian navies, as well as for export. It is designed to outperform the United States-built Mark 54 in and was developed in a special MU90 Hard Kill version for anti-torpedo defence.<ref name=Specs /> It is built by EuroTorp, a consortium of French and Italian companies.
HistoryEdit
The MU90 was the result of separate projects in France and Italy from the 1980s. In France, a project under the direction of Thomson Sintra created the "Murène" in 1989, while in Italy Whitehead started work on an A244 replacement known as the A290. In 1990 the first attempts to merge the two efforts started, a process that was completed in 1993 with the formation of EuroTorp.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
France intended to use the new torpedo on its frigates, Atlantique 2 aircraft, Lynx helicopters and NFH90 helicopters.<ref name=Francebudget2012>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It originally wanted 1000 units, but the end of the Cold War saw this cut to 600 in 1991, 450 in 2000 and finally 300 in 2008.<ref name=Francebudget2012 /> The project cost the government €1,150m in 2012 prices at a unit cost of €1.6m, or €3.8m including development costs.<ref name=Francebudget2012 /> It received 25 torpedoes a year until 2014.<ref name=Francebudget2012 />
DesignEdit
The MU90 is designed to be capable of discriminating between actual and perceived threat, including a bottomed stationary mini-submarine, known versions of anechoic coatings, and various decoys. It is also capable of launch speeds up to Template:ConvertTemplate:Citation needed, allowing it to be dropped from maritime patrol aircraft flying at high speeds, or rocket-assist launchers. Powered by an electric pump-jet, it can be run at "silent" speeds to avoid giving its location away to the submarine, or "dash" at speeds over 29 knots.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It uses a shaped charge warhead that can penetrate any known submarine hull, in particular Soviet double hull designs, while remaining just as deadly in shallow waters where conventional warheads are less effective.
In 1986 France and Italy began a collaboration to develop an anti-submarine missile based on the Italian Otomat missile. France dropped out of the programme but Italy has fitted the MBDA MILAS missile to its Template:Sclasss and FREMM anti-submarine frigates. MILAS is an Template:Convert missile that can deliver a MU90 to Template:Convert.

ExportsEdit
After deciding that its Mark 46 torpedoes were inadequate, Australia set up the JP2070 project in 1998 to buy torpedoes for its Template:Sclasss, Template:Sclasss, AP-3C Orion aircraft, S-70B-2 Seahawk helicopters and planned SH-2G(A) Super Seasprite helicopters.<ref name=ANAO>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Seasprites were cancelled and the Orions and Seahawks were removed from the MU90 programme on budget grounds; their replacements, the P-8 Poseidon and MH-60R Seahawk will use the US Mark 54 torpedo.<ref name=ANAO /> The A$639m<ref name=ANAO /> project to buy a classified number of MU90 has been heavily criticised by the Australian National Audit Office on the grounds of cost, insufficient test firings which failed to reveal defects in the torpedo, and the lack of commonality with the Navy's air-launched torpedoes. The MU90 reached IOC in November 2012.<ref name=ANAO />
