AWACs and E‐3S
Airborne warning aircraft were first developed as a response to the threat of Japan's kamikaze attackers of the later Pacific War. The U.S. Navy acquired a small number of Boeing B‐17 Flying Fortresses, removed the bomb bay from the aircraft, and replaced it with a belly‐mounted radar, designating the new airplane the PB‐1. It foreshadowed a number of subsequent aircraft, both large and small, for the early warning and air control role. One notable example was the air force Lockheed C‐121 Warning Star aircraft, which helped direct air operations over North Vietnam and, in particular, warn American strike aircraft of the presence, location, and strength of opposing North Vietnamese MiG fighters.
Development of the AWACS took over a decade. Boeing flew the first AWACS testbed in 1972, based on a modified jet transport. At the same time, Westinghouse won a competition to produce the critical airborne radar that would perch above the transport, giving it a vaguely “flying saucer” shape. The first production E‐3 entered service with the U.S. Air Force in 1977. Subsequently, advanced models of the aircraft have been sold to the air force, as well as to NATO, Great Britain, France, and Saudi Arabia.
Key to the AWACS, in addition to its radar, is its comprehensive electronic equipment, including the Have Quick secure voice communications system, the Joint Tactical Information Display System (JTIDS), the Mark XV Identification Friend or Foe (IFF) radar, and the Navstar Global Position System space‐based location system. Over twenty crewmen operate the AWACS systems in flight, and it is data‐linked to other aircraft and to ground stations.
The value of AWACS was clearly demonstrated during the Persian Gulf War (1991). In that conflict, AWACS aircraft operated by the U.S. Air Force and the Royal Saudi Air Force managed and controlled over 3,000 coalition aircraft sorties per day. They detected Iraqi threats, and helped pair targets with strike aircraft. They “deconflicted” the air war, preventing so‐called “blue‐on‐blue” attacks. Further, their comprehensive control capabilities enabled the coalition to conduct the war without a single aircraft lost due to a midair collision.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
