Museum, OSI, and GAO packets document Northrop/Boeing Senior Ice defeating Lockheed/Rockwell Senior Peg on 20 October 1981 in the classified Advanced Technology Bomber contest that became the B-2 Spirit—SAP industrial secrecy first, cost and concurrency oversight after unveil.

On 31 July 2013 *The Guardian* published NSA training slides for XKEYSCORE. The deck described a Digital Network Intelligence tool for querying buffered foreign internet traffic—emails, browsing metadata, selectors—while NSA’s 30 July 2013 statement and later PCLOB oversight bound the public record.

Between roughly 1992 and 1999 Spain's Ministry of Defence and Air Force declassified about eighty UFO dossiers (~1,900 pages, cases 1962–1995) now in the Biblioteca Virtual de Defensa; J. J. Benítez denounced the process as wholesale manipulation aimed at Vicente-Juan Ballester Olmos and MOA/MAC officers favoring prosaic closures.

Groom Lake's Area 51 hosted U-2 and A-12/Oxcart flight test programs long denied in public; a CIA history of the U-2 acknowledges the site, separating that documentary base from UFO folklore layered on top.

U.S. FRUS and NS Archive packets show Washington accepting an Israeli nuclear capability under the 1969 Nixon–Meir opacity bargain after Dimona visits missed underground reprocessing. Mordechai Vanunu’s 1986 Sunday Times photos put Machon 2 in public view; arsenal-size claims stay contested.

A late-1950s U.S. Air Force study, Project A119, examined detonating a nuclear weapon on the Moon as a demonstration; declassified documents and participant accounts confirm the paper study, which was never executed.

In July 2000 the FBI disclosed Carnivore (DCS1000), a packet-sniffer for court-ordered internet wiretaps; later reporting described DCSNet as a broader carrier-linked collection suite.

In the 1970s the CIA, using Howard Hughes's Glomar Explorer as cover, attempted to raise a sunken Soviet submarine from the Pacific floor; FOIA fights and later official acknowledgments confirmed the recovery effort known as Project Azorian.

U.S. thermonuclear test Castle Bravo at Bikini Atoll on 1 March 1954 yielded far higher than expected, irradiating Rongelap/Utrik islanders and the Japanese fishing vessel Lucky Dragon No. 5—fallout geography, classification culture, and human-cost aftermath.

On the night of 5–6 September 2007 an airstrike destroyed a remote facility in eastern Syria’s Dair Alzour region—the site open sources call Al-Kibar. For months afterward, public silence held. On 24 April 2008 the White House Press Secretary stated that Syria had been building a covert plutonium-capable reactor with North Korean assistance, that the reactor was not intended for peaceful…

In January 1950 a German-born British physicist at Harwell confessed to passing atomic secrets to Soviet intelligence. In March he was convicted under the Official Secrets Act and sentenced to the maximum fourteen years. The public caption was confession and courtroom. The counterintelligence caption was older: Venona decrypts had already identified him, Allied liaison had focused the hunt, and…

NRL's GRAB (1960–62) was the first U.S. operational ELINT satellite under Galactic Radiation cover; NRO Program C successor POPPY operated 1962–77. DCI-authorized limited GRAB declass (1998) and POPPY fact-of (2004/05) appear in NRO recognition volumes and Program C FOIA paper. Documented/L1. Refuse invented take lists.

Soviet RORSAT Kosmos 954 reentered on 24 January 1978, scattering radioactive debris across the Northwest Territories. Canada–U.S. Operation Morning Light recovery and later liability settlement document nuclear-powered ocean-reconnaissance satellites as crash-disclosure.

The 1975–76 Senate Select Committee chaired by Frank Church exposed COINTELPRO, MKUltra, CHAOS, mail opening, and other intelligence abuses, creating the modern U.S. oversight template and the primary public record for much of the Archive's intel cluster.

In June 1953 a hollow United States nickel turned up in Brooklyn with a microphotograph of coded columns inside. The FBI Laboratory treated it as a probable espionage message and then spent years without a break. In 1957 a defecting Soviet illegal courier, Reino Hayhanen, gave the Bureau the link that turned a coin into a case. Agents arrested a man who called himself Rudolf Ivanovich Abel.

Gladio was the Italian name for NATO-linked stay-behind networks prepared for Soviet occupation; Italian parliamentary inquiries and European reporting established the clandestine structure while debates continue over links to domestic terrorism.

The 1989 FBI/EPA raid on Rocky Flats nuclear-weapons plant exposed environmental crimes; a special grand jury reportedly sought serious charges, but DOJ plea negotiations and sealed materials fueled decades of missing-files controversy.

On 22 September 1979 Vela satellite 6911 recorded a nuclear-like double flash over the South Atlantic. The Ruina panel judged it probably not nuclear; Carter Library / CIA paper assessed high nuclear probability while public policy stayed ambiguous. Archive verdict: contested.

RHYOLITE was a CIA Program B geosynchronous SIGINT/TELINT satellite line, later continued/renamed AQUACADE after codeword compromise, with four successful missions from 1970 in open counts. NS Archive FOIA packets document NRO/NSA bureaucratic conflict; NRO SIGINT history portals acknowledge GEO SIGINT while redacting take. Documented/L1; refuse invented take lists.

Operation Fishbowl (1962) lofted high-altitude nuclear shots from Johnston Atoll; Starfish Prime on 9 July 1962 detonated ~1.4 Mt at ~400 km. Official framing stressed planned effects science; DNA/DTIC and LANL paperwork document EMP far larger than expected, Hawaiian electrical damage, satellite kills, and artificial radiation belts.

HTLINGUAL was the CIA's mail-opening program that intercepted and photographed correspondence of U.S. persons; the Church Committee documented its scale and illegality.

The Advisory Committee on Human Radiation Experiments (ACHRE) documented decades of U.S. isotopic dosing and related studies on unwitting or vulnerable subjects; the 1995 report is the documentary spine.

On the night of 5 September 1945, Igor Gouzenko, a cipher clerk on the staff of the Soviet military attaché in Ottawa, walked out of the embassy with secret documents. The next days were chaotic: failed attempts to hand the material to Canadian officials, a confrontation when Soviet personnel entered his apartment, Ottawa police intervention, and finally RCMP custody.

Operation MONGOOSE was the Kennedy administration’s post–Bay of Pigs covert program, supervised by the Special Group (Augmented) with Edward Lansdale as Chief of Operations, to foster an internal overthrow of the Castro government. FRUS Volume X, NS Archive briefing-book exhibits, and NARA Special Group minutes document objectives, status reviews, and sabotage-option debates. Documented/L1; proposals labeled as proposals.
