The Common Support Aircraft ( CSA ) was a proposed concept, which has been considered by the United States Navy since at least the early 1990s, to replace a number of different fixed-wing aircraft capable of operating from an aircraft carrier and which serve a "support" function, with a single type of aircraft or aircraft platform able to perform all support tasks.
15-567: Current roles deemed "support" by the Navy include: carrier on-board delivery (COD), electronic surveillance (ES), electronic warfare (EW), and airborne early warning (AEW). Another possible support role for a carrier-based aircraft is that of aerial refueling . Among combat roles, while anti-submarine warfare (ASW) and anti-surface warfare (ASUW) are sometimes also considered "support"; fighter , bomber , and ground attack roles are not. Current carrier-based fixed-wing support aircraft used by
30-523: A cargo variant of its twin-piston-engined Grumman S-2 Tracker anti-submarine warfare bomber as the C-1A Trader . (Contrary to popular belief, C-130 Hercules was not tested for COD. ) In the late 1960s Grumman began production of a cargo variant of its twin-turboprop E-2 Hawkeye Airborne Early Warning aircraft known as the C-2A Greyhound . Five Lockheed US-3A Viking aircraft were also used from
45-463: A document constitutes a binding contract depends only on the presence or absence of well-defined legal elements in the text proper of the document (the so-called " four corners "). The required elements are offer and acceptance , consideration , and the intention to be legally bound ( animus contrahendi ). In the US, the specifics can differ slightly depending on whether the contract is for goods (falls under
60-455: A formal, legally enforceable contract (though an MoU is often a first step towards the development of a formal contract). In the United Kingdom , the term MoU is commonly used to refer to an agreement between parts of The Crown . The term is often used in the context of devolution , for example the 1999 concordat between the central Department for Environment, Food and Rural Affairs and
75-418: A matter of law, the title of MoU does not necessarily mean the document is binding or not binding under international law . To determine whether a particular MoU is meant to be a legally binding document (i.e., a treaty), one needs to examine the parties’ intent as well as the signatories' position (e.g., Minister of Foreign Affairs vs. Minister of Environment). A careful analysis of the wording will also clarify
90-420: Is a type of agreement between two ( bilateral ) or more ( multilateral ) parties. It expresses a convergence of will between the parties, indicating an intended common line of action. It is often used either in cases where parties do not imply a legal commitment or in situations where the parties cannot create a legally enforceable agreement. It is a more formal alternative to a gentlemen's agreement . Whether
105-667: The Scottish Environment Directorate . MoUs can also be used between a government agency and a non-commercial, non-governmental organization. In international relations, MoUs fall under the broad category of treaties and should be registered in the United Nations treaty collection. In practice and in spite of the United Nations Office of Legal Affairs ' insistence that registration be done to avoid 'secret diplomacy', MoUs are sometimes kept confidential. As
120-530: The Uniform Commercial Code ) or services (falls under the common law of the state). Many companies and government agencies use MoUs to define a relationship between departments, agencies or closely held companies. In business , an MoU is typically a legally non-binding agreement between two (or more) parties, outlining terms and details of a mutual understanding or agreement, noting each party's requirements and responsibilities—but without establishing
135-460: The C-3, the aircraft would have a wider fuselage, but would retain the original wings, tail assembly, engines and crew compartment. With an unrefueled range of 2,400 nautical miles (4,400 km; 2,800 mi) carrying a 10,000-pound (4,500 kg) load, Lockheed stated that the C-3 would have twice the range of a new C-2, and triple the range of a V-22 Osprey . Unlike other competitors, the C-3 could meet
150-523: The COD role. The Grumman C-2 Greyhound has been the United States Navy 's primary COD aircraft since the mid-1960s. Early United States Navy (USN) recognition of need for a cargo plane capable of carrier landings resulted in airframe conversion of Grumman TBM-3 Avenger torpedo bombers to unarmed seven-passenger COD aircraft designated TBM-3R. Replacement of TBM-3Rs began in the late 1950s. Grumman built
165-656: The US Navy, and which would presumably be replaced by the CSA, include: Other support aircraft used by the US Navy in the recent past include: This United States military article is a stub . You can help Misplaced Pages by expanding it . Carrier onboard delivery Carrier onboard delivery ( COD ) is the use of aircraft to ferry personnel, mail, supplies, and high-priority cargo, such as replacement parts , from shore bases to an aircraft carrier at sea. Several types of aircraft, including helicopters, have been used by navies in

#1732852165427180-619: The critical requirement to transport replacement Pratt & Whitney jet engines for the F-35. The requirement for 35 aircraft would be met from the 91 S-3s currently in storage. In 2015, the Navy published a memorandum of understanding (MoU) for using 4 to 12 HV-22s as COD. On 3 February 2016, the future COD version was designated as the CMV-22B. Several aircraft types have been specifically designed or modified for COD missions: Memorandum of understanding A memorandum of understanding ( MoU )
195-523: The early 1980s to the mid-1990s. The C-2 has remained the U.S. Navy's primary COD vehicle since that time. Several U.S. Navy "Fleet Logistics Support Squadrons" provided COD services aboard carriers since the World War II , including VR-5 , VR-21 , VR-22 , VR-23 , VR-24 , VRC-30 , VRC-40 , and VRC-50 . On 6 October 2012, a MV-22 tilt-rotor aircraft from squadron VMM-165 landed and refueled on board USS Nimitz (CVN-68) . This operation
210-574: The exact nature of the document. The International Court of Justice has provided some insight into the determination of the legal status of a document in the landmark case of Qatar v. Bahrain , 1 July 1994. One advantage of MoUs over more formal instruments is that, because obligations under international law may be avoided, they can often be put into effect without requiring legislative approval. Hence, MoUs are often used to modify and adapt existing treaties, in which case these MoUs have factual treaty status. The decision concerning ratification, however,
225-487: Was part of an evaluation of the feasibility of the MV-22 as a potential replacement for the current C-2 cargo transport aircraft. Further cargo handling trials took place in 2013 on Harry S. Truman . In April 2014 Lockheed Martin announced that they would offer refurbished and remanufactured Lockheed S-3 Vikings as a replacement for the decades-old Northrop Grumman C-2A Greyhound on-board carrier delivery aircraft.
