The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft. This twin-turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which was rapidly becoming obsolete. The aircraft's performance has been upgraded with the E-2B and E-2C versions, where most of the changes were made to the radar and radio communications due to advances in electronic integrated circuits and other electronics. The fourth major version of the Hawkeye is the E-2D, which first flew in 2007. The E-2 was the first aircraft designed specifically for its role, as opposed to a modification of an existing airframe, such as the Boeing E-3 Sentry. Variants of the Hawkeye have been in continuous production since 1960, giving it the longest production run of any carrier-based aircraft.
The Grumman C-2 Greyhound is a twin-engine, high-wing cargo aircraft designed to carry supplies, mail, and passengers to and from aircraft carriers of the United States Navy. Its primary mission is carrier onboard delivery (COD). The aircraft provides critical logistics support to carrier strike groups. The aircraft is mainly used to transport high-priority cargo such as jet engines and special stores, mail, and passengers between carriers and shore bases.
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 the COD role. The Grumman C-2 Greyhound has been the United States Navy's primary COD aircraft since the mid-1960s.
A naval flight officer (NFO) is a commissioned officer in the United States Navy or United States Marine Corps who specializes in airborne weapons and sensor systems. NFOs are not pilots (naval aviators), but they may perform many "co-pilot" or "mission specialist" functions, depending on the type of aircraft. Until 1966, their duties were performed by both commissioned officer and senior enlisted naval aviation observers (NAO).
A naval aviator is a commissioned officer or warrant officer qualified as a crewed aircraft pilot in the United States Navy or United States Marine Corps. United States Coast Guard crewed aircraft pilots are officially designated as "Coast Guard aviators", although they complete the same undergraduate flight training as Navy and Marine Corps crewed aircraft pilots, and are awarded the same aviation breast insignia.
Carrier Airborne Early Warning Squadron 121 (VAW-121), also known as the "Bluetails", is an Airborne Early Warning (AEW) and Command and control (C2) squadron of the United States Navy, operating the E-2D Hawkeye. Established in 1967, the squadron is based at NAS Norfolk. It is currently assigned to Carrier Air Wing 7 and deploys aboard the aircraft carrier USS Abraham Lincoln.
A carrier air wing is an operational naval aviation organization composed of several aircraft squadrons and detachments of various types of fixed-wing and rotary-wing aircraft. Organized, equipped and trained to conduct modern US Navy carrier air operations while embarked aboard aircraft carriers, the various squadrons in an air wing have different but complementary missions, and provide most of the striking power and electronic warfare capabilities of a carrier battle group (CVBG). While the CVBG term is still used by other nations, the CVBG in US parlance is now known as a carrier strike group (CSG).
Training Squadron EIGHT SIX (VT-86), also known as the "Sabrehawks," is a United States Navy advanced jet training squadron based at the Naval Air Station Pensacola, Florida. Training Squadron 86 is a tenant command of Training Air Wing 6. They are a training squadron flying the T-45C Goshawk. Their tailcode is F and their radio callsign is ROKT.
Airborne Command and Control Squadron 123 (VAW-123) is based at Naval Station Norfolk, flying the E-2C Hawkeye. They are attached to Carrier Air Wing Three (CVW-3) while deployed aboard USS Dwight D. Eisenhower. The squadron nickname is the Screwtops.
Airborne Command & Control Squadron 116 (VAW-116) is a US Navy Command and Control Squadron that deploys aboard USS Nimitz as part of Carrier Air Wing Seventeen, flying the E-2C Hawkeye 2000 aircraft. VAW-116 is stationed at Naval Base Ventura County under the cognizance of Commander, Airborne Command Control and Logistics Wing (COMACCLOGWING). The current commanding officer is Commander Phillip J. Sheridan.
Airborne Command & Control Squadron 117 (VAW-117) is an airborne early warning (AEW) and command and control (C2) squadron. Nicknamed "The Wallbangers,” it flies the E-2D Hawkeye, the only carrier-capable command and control aircraft. The squadron is based in NAS Point Mugu and deploys as part of Carrier Air Wing 9 (CVW-9) on board USS Abraham Lincoln.
Airborne Command & Control Squadron 113 (VAW-113), known as "Black Eagles", was established on 20 April 1967 flying the E-2A Hawkeye.
Fleet Logistics Support Squadron 40 (VRC-40), also known as the "Rawhides", is a United States Navy fleet logistics support squadron based at NS Norfolk. Commissioned in 1960, it is one of only two active fleet logistics squadrons in the Navy, the other being VRC-30.
Carrier Airborne Early Warning Squadron 126 (VAW-126), nicknamed the "Seahawks", is a carrier airborne early warning squadron of the United States Navy. The squadron is based at NS Norfolk, equipped with five E-2D Hawkeye aircraft.
Carrier Airborne Early Warning Squadron 112 (VAW-112) is an inactive United States Navy squadron. It was nicknamed the "Golden Hawks". VAW-112 flew the E-2C Hawkeye out of NAS Point Mugu and last deployed in 2013 as part of Carrier Air Wing 9 (CVW-9) on board USS John C. Stennis.
The Hawker Siddeley P.139B was a proposed airborne early warning aircraft intended to operate from aircraft carriers of the Royal Navy. The P.139B formed part of the a major equipment procurement plan for the RN in the 1960s intended to give the service a force of new, modern carriers capable of operating air groups consisting of equally modern aircraft. However, cuts in defence spending by the British government in the mid-1960s meant that these proposals never came to fruition.
Carrier Airborne Early Warning Squadron 78 (VAW-78), nicknamed the "Fighting Escargots" or "Slugs" was a reserve Carrier Airborne Early Warning Squadron of the U.S. Navy. It was established on 1 July 1970 as part of a major reorganization of the Naval Air Reserve and deactivated on 31 March 2005.
Carrier Airborne Early Warning Squadron 12 (VAW-12), nicknamed the "Bats", was a U.S. Navy Carrier Airborne Early Warning Squadron. The squadron was disestablished on 1 April 1967.
Carrier Airborne Early Warning Squadron 110 (VAW-110), nicknamed the "Firebirds", was an aviation unit of the United States Navy based at NAS Miramar.The Firebirds were a training squadron for the E-2 Hawkeyes. It was disestablished in September 1994.
