Question: What naval aviation branch, known as COAN, utilizes the Gringo-Gaucho maneuvers along with the US Navy?

<P0-S0>  The US Navy refers to them as Southern Seas in their last edition. <P0-S1>  Gringo and Gaucho are linguistic and folkloric designations of long standing, respectively. <P0-S2> Gringo-Gaucho are a contingent set of maneuvers performed between the Argentine Naval Aviation and United States Navy's aircraft carriers. <SEP> <P1-S0> The Indian Navy currently operates twenty-one air squadrons. Of these, ten operate fixed-wing aircraft, eight are helicopter squadrons and the remaining three are equipped with unmanned aerial vehicles (UAV). <P1-S1>  Building on the legacy inherited from the Royal Navy prior to Indian independence, the concept of naval aviation in India started with the establishment of Directorate of Naval Aviation at Naval Headquarters (NHQ) in early 1948. <P1-S2>  Later that year officers and sailors from the Indian Navy were sent to Britain for pilot training. <P1-S3>  In 1951, the Fleet Requirement Unit (FRU) was formed to meet the aviation requirements of the navy. <P1-S4>  On 1 January 1953, the charge of Cochin airfield was handed over to the navy from the Directorate General of Civil Aviation. <P1-S5>  On 11 March, the FRU was commissioned at Cochin with ten newly acquired Sealand aircraft. <P1-S6>  The navy's first air station, INS "Garuda", was commissioned two months later. <P1-S7>  From February 1955 to December 1958, ten Firefly aircraft were acquired. <P1-S8>  To meet the training requirements of the pilots, the indigenously developed HAL HT-2 trainer was inducted into the FRU. <P1-S9>  On 17 January 1959, the FRU was commissioned as Indian Naval Air Squadron (INAS) 550, to be the first Indian naval air squadron. <P1-S10>  In the following two years, three more naval air squadrons—INAS 300, INAS 310 and INAS 551—were commissioned. <P1-S11>  The first two operated from the newly purchased aircraft carrier INS "Vikrant" flying Sea Hawks and Alizés, whereas the latter one, equipped with Vampires, was used for training purposes. <SEP> <P2-S0> The Australian Fleet Air Arm Museum, formerly known as Australia's Museum of Flight, is a military aerospace museum located at the naval air station HMAS "Albatross" , near Nowra, New South Wales. <P2-S1>  The museum was opened in 1990, although efforts to preserve artifacts related to Australia's naval aviation history began in 1974. <P2-S2>  The museum houses aircraft used throughout the history of the Fleet Air Arm, the naval aviation branch of the Royal Australian Navy (RAN), along with other aircraft of relevance to Australia's aviation history, and memorabilia relating to Australian aircraft carriers. <P2-S3>  The museum includes 34 aircraft and helicopters in its collection. <P2-S4>  It is open to the public daily, except for major public holidays. <P2-S5>  The museum building is also home to Albatross Aero Club. <SEP> <P3-S0> The Argentine Naval Aviation (Spanish: Comando de Aviación Naval Argentina, COAN) is the naval aviation branch of the Argentine Navy and one of its four operational commands. <P3-S1>  Argentina, along with Brazil is one of two South American countries to have operated two aircraft carriers
