Black project is an informal term used to describe a highly classified, top-secret military or defense project that is not publicly acknowledged by government, military personnel, or contractors.
In the United States, the formal term for a black project is an unacknowledged special access program (SAP). Black projects receive their funding from the black budget.
The US depends on private defense contractors to develop and build military equipment. The two most notable examples are Lockheed Martin and Northrop Grumman. The R&D department of Lockheed Martin is commonly referred to as Skunk Works; it is responsible for a number of aircraft designs, highly classified R&D programs, and exotic aircraft platforms.
Two well known sites for testing of black projects are the Nevada Test site and Area 51.
Below are examples of previously unacknowledged black projects categorized per country.
The Northrop B-2 Spirit, also known as the Stealth Bomber, is an American heavy strategic bomber, featuring low-observable stealth technology designed to penetrate dense anti-aircraft defenses. A subsonic flying wing with a crew of two, the plane was designed by Northrop as the prime contractor, with Boeing, Hughes, and Vought as principal subcontractors, and was produced from 1987 to 2000. The bomber can drop conventional and thermonuclear weapons, such as up to eighty 500-pound class (230 kg) Mk 82 JDAM GPS-guided bombs, or sixteen 2,400-pound (1,100 kg) B83 nuclear bombs. The B-2 is the only acknowledged in-service aircraft that can carry large air-to-surface standoff weapons in a stealth configuration.
The RQ-3 DarkStar is an unmanned aerial vehicle (UAV). Its first flight was on March 29, 1996. The Department of Defense terminated DarkStar in January 1999, after determining the UAV was not aerodynamically stable and was not meeting cost and performance objectives.
The Northrop Grumman RQ-4 Global Hawk is a high-altitude, remotely-piloted surveillance aircraft introduced in 2001. It was initially designed by Ryan Aeronautical, and known as Tier II+ during development. The RQ-4 provides a broad overview and systematic surveillance using high-resolution synthetic aperture radar (SAR) and electro-optical/infrared (EO/IR) sensors with long loiter times over target areas.
Northrop Grumman Corporation is an American multinational aerospace and defense company. With 95,000 employees and an annual revenue in excess of $30 billion, it is one of the world's largest weapons manufacturers and military technology providers. The firm ranked No. 101 on the 2022 Fortune 500 list of America's largest corporations.
The Northrop/McDonnell Douglas YF-23 is an American single-seat, twin-engine, stealth fighter technology demonstrator prototype designed for the United States Air Force (USAF). The design team, with Northrop as the prime contractor, was a finalist in the USAF's Advanced Tactical Fighter (ATF) demonstration/validation competition, battling the YF-22 team for full-scale development and production. Two YF-23 prototypes were built.
The Northrop Grumman X-47 is a demonstration unmanned combat aerial vehicle. The X-47 began as part of DARPA's J-UCAS program, and is now part of the United States Navy's UCAS-D program to create a carrier-based unmanned aircraft. Unlike the Boeing X-45, initial Pegasus development was company-funded. The original vehicle carries the designation X-47A Pegasus, while the follow-on naval version is designated X-47B.
The Northrop Grumman MQ-4C Triton is an American high-altitude long endurance unmanned aerial vehicle (UAV) developed for and flown by the United States Navy and Royal Australian Air Force as a surveillance aircraft. Together with its associated ground control station, it is an unmanned aircraft system (UAS). Developed under the Broad Area Maritime Surveillance (BAMS) program, the Triton is intended to provide real-time intelligence, surveillance and reconnaissance missions (ISR) over vast ocean and coastal regions, continuous maritime surveillance, conduct search and rescue missions, and to complement the Boeing P-8 Poseidon maritime patrol aircraft.
The Dassault nEUROn is an experimental unmanned combat aerial vehicle (UCAV) being developed with international cooperation, led by the French company Dassault Aviation. Countries involved in this project include France, Greece, Italy, Spain, Sweden and Switzerland. The design goal is to create a stealthy, autonomous UAV that can function in medium-to-high threat combat zones.
Joint Unmanned Combat Air Systems, or J-UCAS, was the name for the joint U.S. Navy and U.S. Air Force unmanned combat air vehicle procurement project. Originally two separate projects of the U.S. Air Force and Navy respectively: UCAV and UCAV-N; both programs merged in 2003. The two vehicles involved in J-UCAS were the Boeing X-45 and Northrop Grumman X-47A Pegasus, originally part of UCAV and UCAV-N respectively. J-UCAS was managed by the Defense Advanced Research Projects Agency. In the 2006 Quadrennial Defense Review, it was stated that the J-UCAS program would be terminated and instead a new long-range strategic bomber program, Next-Generation Bomber, for the Air Force would launch. The program was revitalized into a Navy-only program named UCAS-D.
The Northrop Grumman X-47B is a demonstration unmanned combat aerial vehicle (UCAV) designed for aircraft carrier-based operations. Developed by the American defense technology company Northrop Grumman, the X-47 project began as part of DARPA's J-UCAS program, and subsequently became part of the United States Navy's Unmanned Combat Air System Demonstration (UCAS-D) program. The X-47B is a tailless jet-powered blended-wing-body aircraft capable of semi-autonomous operation and aerial refueling.
The EADS Barracuda was a jet powered unmanned aerial vehicle (UAV), EADS, used for the role of aerial reconnaissance and also combat. The aircraft was a joint venture between Germany and Spain.
The Next-Generation Bomber was a program to develop a new medium bomber for the United States Air Force. The NGB was initially projected to enter service around 2018 as a stealthy, subsonic, medium-range, medium payload bomber to supplement and possibly—to a limited degree—replace the U.S. Air Force's aging bomber fleet. The Long Range Strike Bomber (LRS-B) heavy bomber program superseded the NGB program.
Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers.
The Lockheed Martin RQ-170 Sentinel, nicknamed Wraith, is an American unmanned aerial vehicle (UAV) developed by Lockheed Martin and operated by the United States Air Force (USAF) for the Central Intelligence Agency (CIA). While the USAF has released few details on the UAV's design or capabilities, defense analysts believe that it is a stealth aircraft fitted with aerial reconnaissance equipment. Introduced in 2007, it was deployed to Afghanistan in late 2007, and to South Korea two years later, in September 2009. Some images and details of the aircraft were released after Iran captured an RQ-170 in 2011. It has a flying wing design, and uses a single engine, speculated to be either a General Electric TF34 turbofan or a Garrett TFE731.
The Long Range Strike Bomber (LRS-B) is a development and acquisition program to develop a long-range strategic bomber for the United States Air Force, intended to be a heavy-payload stealth aircraft that can deliver thermonuclear weapons. Initial capability is planned for the mid-2020s. A request for proposals to develop the aircraft was issued in July 2014. The Air Force plans to procure at least 100 and potentially up to 200 of the LRS-B aircraft for an estimated $550 million each. A development contract was awarded to Northrop Grumman for its B-21 Raider in October 2015. Much about the project is highly classified and little information is available to the public. As of late 2019, it was known that construction of the aircraft had begun, and on December 2, 2022, it was unveiled to the public.
The Lockheed Martin Sea Ghost was a proposal to fulfill the United States Navy's requirement for an Unmanned Carrier-Launched Airborne Surveillance and Strike aircraft.
The Lockheed Martin SR-72, colloquially referred to as "Son of Blackbird", is an American hypersonic UAV concept intended for intelligence, surveillance and reconnaissance (ISR) proposed privately in 2013 by Lockheed Martin as a successor to the retired Lockheed SR-71 Blackbird. In 2018, company executives said an SR-72 test vehicle could fly by 2025 and enter service in the 2030s.
The Northrop Grumman RQ-180 is an American stealth unmanned aerial vehicle (UAV) surveillance aircraft intended for contested airspace. As of 2019, there had been no images or statements released, but evidence points to the existence of the RQ-180 and its use in regular front-line service.
