The EA-6B Prowler is a twin-engine, mid-wing aircraft manufactured by Northrop Grumman Aerospace Corporation as a modification of the basic A-6 Intruder airframe. Designed for carrier and advanced base operations, the Prowler is a fully integrated electronic warfare system combining long-range, all-weather capabilities with advanced electronic countermeasures. A forward equipment bay and pod-shaped faring on the vertical fin house the additional avionics equipment. It is the United States Navy's and the United States Marine Corps's primary electronic warfare aircraft. The primary mission of the aircraft is to support strike aircraft and ground troops by interrupting enemy electronic activity and obtaining tactical electronic intelligence within a combat area.

Since the retirement of the EF-111 Raven in 1995, it is the only aerial radar jammer in the DOD arsenal. It has been utilized in practically every US combat operation and is frequently loaned to the US Air Force. The increased usage has shorted the airframes' lifetimes and they are slated to be replaced by the EA-18G Growler.

Development

The Prowler has a crew of four, a pilot and three Electronic Counter-measures Officers (known as ECMOs). Powered by two non-afterburning Pratt & Whitney J52-P408 turbojet engines, it is capable of speeds of up to 950 km/h with a range of 1,840 kilometers. Since EW operations are very demanding, the Prowler is a high-maintenance aircraft and also undergoes more frequent equipment upgrades than any other aircraft in the Navy.

Although designed as an electronic escort and command and control platform for strike missions, the EA-6B is also capable of attacking surface targets on its own especially radars, SAM launchers, and other enemy defenses. The AGM-88 HARM (High-speed Anti-Radiation Missile) is the main offensive strike weapon of the Prowler. In addition, the aircraft is highly capable of conducting electronic intelligence (ELINT) collection.

An earlier EA-6A "Electric Intruder" was developed during the Vietnam War. Basically a straightforward conversion of the standard two-seat A-6 airframe fitted with EW equipment, it was essentially an interim aircraft used only by a few USMC squadrons.

The much more advanced and substantially redesigned EA-6B first flew on 25 May 1968 and entered service with VAQ-132 'Scorpions' in July 1971 and saw combat in Vietnam a few months later.

During 1993-1994, an Advanced Capability EA-6B (ADVCAP) prototype was tested with excellent results but was later dropped due to budget restrictions.

About 125 Prowlers remain today, divided between 12 Navy, 4 Marine, and 3 joint Navy-Air Force squadrons. When the US Air Force retired the EF-111 Raven, an aircraft similar in mission to the EA-6B, because of budget cuts the Navy agreed to share with it a number of "expeditionary" Prowler squadrons composed of Navy and USAF personnel. The Prowler is inaffectionately known as the "Queer," primarily because of the distinct coating on the canopy, designed to protect the crew from powerful electromagnetic emissions.

Though it remains in service today, the EA-6B Prowler is slated to be replaced after 2009 by the EA-18G Growler, a new electronic warfare derivative of the F/A-18F Super Hornet.

Incidents

It was an USMC EA-6B Prowler that caused the Cavalese cable-car disaster in 1998, cutting the cables of a ski-lift in Italy and killing 20.
In 1981 an EA-6B crashed onto the flight deck of the USS Nimitz and caused a blaze, killing the flight crew and several deck personnel.
The latest incident occurred March 3, 2006 near Pendleton, Oregon, USA.
Despite the fact that to date no Prowler has ever been lost in combat, about forty were already destroyed in various accidents.
