Chandler is a city in Maricopa County, Arizona, United States, and a suburb in the Phoenix-Mesa-Chandler Metropolitan Statistical Area. It is the fourth-most populous city in Arizona, after Mesa, Tucson, and Phoenix. Chandler is considered to be a part of the East Valley.

As of the 2020 census, the population of Chandler was 275,987, up from 236,123 at the 2010 census. Chandler is a commercial and tech hub for corporations like Intel, Northrop Grumman, Wells Fargo, PayPal and Boeing.

USCGC Bertholf (WMSL-750) is the first Legend-class maritime security cutter of the United States Coast Guard. She is named for Commodore Ellsworth P. Bertholf, fourth commandant of both the Revenue Cutter Service and Coast Guard.

In 2005, construction began at Northrop Grumman's Ship Systems Ingalls Shipyard in Pascagoula, Mississippi. She was launched on September 29, 2006, christened November 11, 2006, and commissioned on August 4, 2008. The cutter's home port is Alameda, California. Bertholf was the first to fire the Bofors 57 mm gun aboard a U.S. vessel on 11 February 2008.

The Compton Gamma Ray Observatory (CGRO) was a space observatory detecting photons with energies from 20 keV to 30 GeV, in Earth orbit from 1991 to 2000. The observatory featured four main telescopes in one spacecraft, covering X-rays and gamma rays, including various specialized sub-instruments and detectors. Following 14 years of effort, the observatory was launched from Space Shuttle Atlantis during STS-37 on April 5, 1991, and operated until its deorbit on June 4, 2000. It was deployed in low Earth orbit at 450 km (280 mi) to avoid the Van Allen radiation belt. It was the heaviest astrophysical payload ever flown at that time at 16,300 kilograms (35,900 lb).

Costing $617 million, the CGRO was part of NASA's Great Observatories series, along with the Hubble Space Telescope, the Chandra X-ray Observatory, and the Spitzer Space Telescope. It was the second of the series to be launched into space, following the Hubble Space Telescope. The CGRO was named after Arthur Compton, an American physicist and former chancellor of Washington University in St. Louis who received the Nobel Prize for work involved with gamma-ray physics. CGRO was built by TRW (now Northrop Grumman Aerospace Systems) in Redondo Beach, California. CGRO was an international collaboration and additional contributions came from the European Space Agency and various universities, as well as the U.S. Naval Research Laboratory.

The Lockheed Martin F-35 Lightning II is an American family of single-seat, single-engine, supersonic stealth strike fighters. A multirole combat aircraft designed for both air superiority and strike missions, it also has electronic warfare and intelligence, surveillance, and reconnaissance capabilities. Lockheed Martin is the prime F-35 contractor with principal partners Northrop Grumman and BAE Systems. The aircraft has three main variants: the conventional takeoff and landing (CTOL) F-35A, the short take-off and vertical-landing (STOVL) F-35B, and the carrier variant (CV) catapult-assisted take-off but arrested recovery (CATOBAR) F-35C.

The aircraft descends from the Lockheed Martin X-35, which in 2001 beat the Boeing X-32 to win the Joint Strike Fighter (JSF) program intended to replace the F-16 Fighting Falcon, F/A-18 Hornet, and the McDonnell Douglas AV-8B Harrier II "jump jet", among others. Its development is primarily funded by the United States, with additional funding from program partner countries from the North Atlantic Treaty Organization (NATO) and close U.S. allies, including Australia, Canada, Denmark, Italy, the Netherlands, Norway, the United Kingdom, and formerly Turkey. Several other countries have also ordered, or are considering ordering, the aircraft.

Pegasus is an air-launched multistage rocket developed by Orbital Sciences Corporation (OSC) and later built and launched by Northrop Grumman. Pegasus is the world's first privately developed orbital launch vehicle. Capable of carrying small payloads of up to 443 kg (977 lb) into low Earth orbit, Pegasus first flew in 1990 and remained active as of 2025. The vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 12,000 m (39,000 ft) using a first stage wing and a tail to provide lift and attitude control while in the atmosphere. The first stage does not have a thrust vector control (TVC) system.

TRW Inc., or Thompson Ramo Wooldridge Inc., was an American corporation involved in a variety of businesses, mainly aerospace, electronics, automotive, and credit reporting. The company was founded in 1901 and lasted for just over a century until being acquired by Northrop Grumman in 2002. It spawned a variety of corporations, including Pacific Semiconductors, The Aerospace Corporation, Bunker-Ramo and Experian. TRW was instrumental in the development of spacecraft during the Space Race, including Pioneer 1, Pioneer 10, and the Apollo program. TRW also played a significant role in the US defense industry, leading the development of the United States' first ICBM and later the Titan missile. The corporation was listed as #57 on the 1986 Fortune 500 list, and had 122,258 employees in 2000.

The Mk44 Bushmaster II is a 30 mm chain gun manufactured by Northrop Grumman. It is a derivative of the 25 mm M242 Bushmaster, and uses 70% of the same parts as the M242 while increasing the firepower by as much as 50% with the 20% increase in caliber size. The barrel is chromium-plated for extended life. The gun uses standard GAU-8 Avenger ammunition that is available in API (Armor-Piercing Incendiary), HEI (High-Explosive Incendiary) and APFSDS-T (Armor-Piercing Fin-Stabilized Discarding Sabot-Tracer) variants.

The gun can be converted to a caliber of 40×180 mm, which involves changing the barrel and a few key parts, to use the SuperShot 40 cartridge. It can also be converted to use the 30×170 mm RARDEN cartridge.
