2005 to conduct trials to ensure that she was materially up to operational standard before conducting operational sea training in the New Year. Edinburgh then took part in Exercise Neptune Warrior off the coast of Scotland; conducted a High Seas Firing of her Sea Dart missile system and then took part in the multi-national BALTOPS exercise in the Baltic Sea. The time in the Baltic included visits to Sweden, Germany and Estonia. During the visit to Estonia, Edinburgh took part in the naval parade celebrating an Estonian national holiday. In autumn 2006 Edinburgh deployed to the Falkland Islands remaining there until June 2007. The extended nature of the deployment was made possible by the "Sea Swap" trial, an initiative to try and extend operational deployments by keeping the ship in theater and swapping crews; in this case the crews of HMS EXETER and EDINBURGH. The swap was completed in March and while not an unqualified success, it did achieve the object of the trial in keeping a ship on station for a longer period of time. EDINBURGH was the center piece for the 25th anniversary celebration of the liberation of the Falkland Islands in June 2007 and she finally returned home to Portsmouth in August 2007 via, Rio de Janeiro, Fortaleze in Brazil and Tenerife. The crews of both ships then "unswapped" in September 2007. Edinburgh was deployed to the Middle and Far East from February until late July 2008 as part of Orion 2008, including a visit to Singapore and operations in the Gulf, during which she took part in an interception of a drugs cargo. 2010 refit Edinburgh became the last Type 42 destroyer to undergo a refit when she entered dry dock on 25 January 2010 at BAE Systems Surface Ships shipyard in Portsmouth Naval Base for work to keep the ship in service until 2013. Under a £17.5 million contract, the company refurbished the destroyer's weapons and communications systems, added a transom flap to the stern and applied a coat of International Paint's Intersleek 900 foul-release paint. The refit included a renewal of crew living quarters, catering facilities and laundry equipment. Edinburghs four Rolls-Royce gas turbine engines were removed; with two being replaced by new units (starboard Olympus TM3B and port Tyne RM1C). In a company statement on 18 January 2010, BAE Systems said that the modifications would cut fuel consumption by 15 per cent. Edinburgh
