tajne-programy: Advanced Aerospace Threat Identification Program

Evidence: 100 • authority: 72

The Advanced Aerospace Threat Identification Program (AATIP) was an unclassified but unpublicized investigatory effort funded by the United States Government to study unidentified flying objects (UFOs) or unexplained aerial phenomena (UAP). The program was first made public on December 16, 2017. The program began in 2007, with funding of $22 million over the five years until the available appropriations were ended in 2012. The program began in the U.S. Defense Intelligence Agency. According to the Department of Defense, the AATIP ended in 2012 after five years, however reporting suggested that U.S. government programs to investigate UFOs continued. This was confirmed in June 2020 with the a…

The Apollo program, also known as Project Apollo, was the United States human spaceflight program led by NASA, which landed the first humans on the Moon in 1969. The Apollo program was conceived in 1960 in the Dwight D. Eisenhower presidency during Project Mercury and executed after Project Gemini. The Apollo program was later dedicated to President John F. Kennedy's national goal, "before this decade is out, of landing a man on the Moon and returning him safely to the Earth" in his address to the U.S. Congress on May 25, 1961. Kennedy's goal was accomplished on the Apollo 11 mission, when astronauts Neil Armstrong and Buzz Aldrin landed their Apollo Lunar Module (LM) on July 20, 1969, and…

A sixth-generation fighter is a jet-powered fighter aircraft more advanced than the fifth-generation jet fighters currently in service and development. Key characteristics include advanced stealth technology, increased range, beyond-visual-range weapons, and potentially aerial manned-unmanned teaming. As of 2026, various national and multinational programs are in progress, with the first sixth-generation fighters expected to enter service in the 2030s. China is the first nation to publicly fly prototypes widely referred to as sixth-generation fighter aircraft. China has test-flown two sixth-generation prototypes, tentatively named the Chengdu J-36 and Shenyang J-50, in 2024. In 2025, the Un…

The KAI KF-21 Boramae (Korean: KF-21 보라매; lit. 'KF-21 Hunting Hawk'; formerly KF-X; commonly KF-21) is a South Korean twin-engine fighter aircraft. The initial goal of the program was to develop an indigenous multirole fighter for the Republic of Korea Air Force (ROKAF). The airframe of Blocks I and II adopts semi-stealth technology with partially embedded external weapons and MUM-T (Manned-Unmanned Teaming) capabilities, while full stealth, including internal weapons bays is planned for the Block III or KF-21EX variant. As South Korea's second domestic fighter jet development program following the FA-50 series, the KF-21 makes the nation the fourth in the world—joining the United States, C…

The Advanced Tactical Fighter (ATF) was a program undertaken by the United States Air Force to develop a next-generation air superiority fighter to replace the F-15 Eagle. The proposed fighter was intended to counter emerging worldwide threats in the 1980s, including Soviet Sukhoi Su-27 and Mikoyan MiG-29 fighters under development, Beriev A-50 airborne warning and control systems (AWACS), and increasingly sophisticated surface-to-air missile systems. The program resulted in the F-22 Raptor. The ATF would make a leap in performance and capability by taking advantage of emerging technologies, including advanced avionics and flight control systems, more powerful propulsion systems, and stealt…

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics.. Oscillatory dynamics play a central role in the description of a broad spectrum of physical systems. While often well-approximated by linear models, the essential long-term evolution and stability of these systems are frequently determined by subtle nonlinearities. The characterization of such weakly nonlinear systems from observational data is a central challenge in system identification, a task made difficult by the immense disparity in magnitude between faint nonlinear signatures and the dominant linear response. Herein, we introduce Evolutionary Learning Oscillator with Weak Nonlinearity (EvLOWN), a data-driven m…

The All-domain Anomaly Resolution Office (AARO) is an office within the United States Office of the Secretary of Defense that investigates unidentified flying objects (UFOs) and other phenomena in the air, sea, and/or space and/or on land: sometimes referred to as "unidentified aerial phenomena" or "unidentified anomalous phenomena" (UAP). Its first director was physicist Sean Kirkpatrick who reported to then deputy defense secretary Kathleen Hicks. Its current director is Jon T. Kosloski. Established in 2022, AARO was preceded by the Unidentified Aerial Phenomena Task Force (UAPTF), a 2020 to 2021 program within the Office of Naval Intelligence used to "standardize collection and reporting…

Investigation of UFO reports by the United States government has taken place under multiple branches and agencies, past and current, since 1947. In spite of decades of interest, there remains no evidence that there are any UFOs with extraterrestrial origins and, indeed, those identified all have been shown to be natural phenomena, human technology, misapprehensions, delusions, or hoaxes. The first programs were established under the U.S. Air Force between 1947 and 1969 with Project Sign, Project Grudge, and finally Project Blue Book. The Condon Report in 1968 led the U.S. to stop spending resources on the effort to receive and analyze UFO reports because "nothing has come from the study of…
