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 AEW, 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.
An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack aircraft. AEW&C units are also used to carry out aerial surveillance over ground and maritime targets, and frequently perform battle management command and control (BMC2). When used at altitude, the radar system on AEW&C aircraft allows the operators to detect, track and prioritize targets and identify friendly aircraft from hostile ones in real-time and from much farther away than ground-based radars. Like ground-based radars, AEW&C systems can be detected and targeted by opposing forces, but due to aircraft mobility and extended sensor range, they are much less vulnerable to counter-attacks than ground systems.
The Gulfstream G550 is a business jet aircraft produced by General Dynamics' Gulfstream Aerospace unit in Savannah, Georgia, US. The certification designation is GV-SP. A version with reduced fuel capacity was marketed as the G500. Gulfstream ceased production of the G550 in July 2021.
The Republic of Singapore Air Force (RSAF) is the aerial service branch of the Singapore Armed Forces (SAF) responsible for controlling and defending the airspace of the country, and providing air support to the Army and Navy. It was established in 1968 as the Singapore Air Defence Command (SADC) before renaming to its current name in 1975.
The Boeing E-7 Wedgetail, also marketed as the Boeing 737 AEW&C, is a twin-engine airborne early warning and control aircraft based on the Boeing 737 Next Generation design. It has a fixed, active electronically scanned array radar antenna instead of a rotating one as with the 707-based Boeing E-3 Sentry. The E-7 was designed for the Royal Australian Air Force (RAAF) under "Project Wedgetail" and designated E-7A Wedgetail.
The Gulfstream V is a long-range, large business jet aircraft produced by Gulfstream Aerospace, derived from the previous Gulfstream IV. It flies up to Mach 0.885, up to 51,000 feet (16,000 m) and has a 6,500 nmi (12,000 km) range. It typically accommodates four crew and 14 passengers. It first flew on November 28, 1995, and entered service in June 1997. It is used by the US military under the designation C-37A. It is followed by an improved version, the Gulfstream 550.

The Sembawang Air Base is a military airbase of the Republic of Singapore Air Force (RSAF) located at Sembawang, in the northern part of Singapore. The base motto is Swift and Resolute.
Changi Air Base (East), or Changi East Complex, is a facility extending the facilities of Changi Air Base, the existing facilities hence renamed Changi Air Base (West). Built on a 2 square kilometre site of reclaimed land, the new base was located approximately 2 kilometres east of Changi Airport and approximately 1.5 kilometres west of Changi Naval Base. Groundbreaking took place on 15 July 2002 and it was officially opened on 29 November 2004. A new runway (02R/20L) was built and the length was approximately 2,748 metres (9,015 ft), it has since been lengthened to 4,000 metres.
The 145 Squadron "Hornet" is a strike fighter squadron of the Republic of Singapore Air Force based currently at Changi Airbase (East) which is a new airbase, opened in 2004, to the east of Singapore Changi Airport on reclaimed land. Due to ongoing construction works for Changi Airport Terminal 5 & runway expansion, this flight squadron is based at Tengah Airbase. With the hornet as its mascot, the squadron's motto is "Swift & Valiant".
The ST Aerospace A-4SU Super Skyhawk is a major upgrade project of the Douglas A-4S Skyhawk attack aircraft undertaken by Singapore Aircraft Industries in the 1980s. It was used exclusively by the Republic of Singapore Air Force (RSAF), serving in the fighter-bomber role from 1989 until retirement from front line service in 2005. Since mid-1999, the A-4SU took on the additional role of being the designated advanced jet trainer (AJT) aircraft for the RSAF's AJT training program/detachment in Cazaux, France.
The Black Knights is the official aerobatics team of the Republic of Singapore Air Force (RSAF) featuring six F-16Cs Fighting Falcon in formation flight. The Black Knights' emblem is sported on the red vertical tail of each of the team's aircraft and the team's name is emblazoned on both sides of the aircraft which are painted in red and white—the national colours of Singapore.

The 192 Squadron of the Israeli Air Force (IAF), also known as the Daya (Milvus) Squadron, was formed in July 1978 with several E-2 Hawkeye Airborne Early Warning aircraft. The squadron served in a reconnaissance role during the 1982 Lebanon War and in other operations since.
The EL/W-2085 is an airborne early warning and control (AEW&C) multi-band radar system developed by Israel Aerospace Industries (IAI) and Elta Electronics Industries of Israel. Its primary objective is to provide intelligence to maintain air superiority and conduct surveillance. The system is currently in-service with Israel, Italy, and Singapore.
