Before Los Alamos needed implosion lenses, the Manhattan Engineer District needed uranium. The richest known pitchblende on Earth sat at Shinkolobwe in Katanga, Belgian Congo, under Union Minière du Haut-Katanga.

On 1 May 1960 a U.S. U-2 spy plane was shot down over the Soviet Union; Eisenhower's cover story collapsed when the Soviets produced pilot Francis Gary Powers and wreckage.

VENONA was the U.S. Army/NSA program that decrypted Soviet intelligence cables from the 1940s; historical releases document both real espionage identifications and later political overclaim.

In the Sea of Okhotsk, U.S. Navy deep-diving teams from special-mission submarines placed recording devices on a Soviet military undersea communications cable. The joint Navy–NSA–CIA collection effort later nicknamed Ivy Bells captured traffic that Moscow treated as physically secure—much of it unexpectedly plain.

Operation Fortitude, under the Bodyguard deception frame for OVERLORD, aimed German attention at the Pas-de-Calais and Norway while Allies landed in Normandy. MI5’s Double-Cross System—documented in TNA KV files, Service history pages, and Masterman’s B1A report—fed controlled agent traffic that supported that story. The papers settle a deception system, not a claim that spies alone won the war.

USAF MOL (announced 1965, cancelled 1969) planned Gemini-B crews operating a classified reconnaissance telescope (KH-10/DORIAN). Declassification waves show a crewed spy-station path killed by cheaper unmanned systems.

Declassified cables and Church Committee findings document U.S. covert action and ITT corporate intrigue around Salvador Allende's government before the 1973 Chilean coup.

Operation CHAOS was the CIA's domestic surveillance program against antiwar and dissident groups; Rockefeller and Church investigators exposed its files on thousands of Americans.

CIA MKUltra Subproject 68 funded behavioral research at Montreal’s Allan Memorial Institute under Ewen Cameron through the Society for the Investigation of Human Ecology. FOIA abstracts and the 1977 Senate joint hearing document the subproject’s verbal-signal and chemical-agent framing after partial MKUltra file destruction.

On 18 March 1969, B-52s struck Base Area 353 inside Cambodia under the first “Breakfast” sortie of what became Operation Menu—a secret U.S.

After 1945, U.S. intelligence sponsored Gen. Reinhard Gehlen's former Fremde Heere Ost cadre as an anti-Soviet network that became the core of West Germany's BND—trading Nazi-era expertise for Cold War coverage.

CIA's PBSUCCESS operation overthrew Guatemalan President Jacobo Árbenz in 1954 amid United Fruit Company land-reform conflicts; FRUS and CIA file releases document the corporate-state coup fusion.

In the late 1950s, physicists at General Atomic sketched a spaceship that would ride a chain of nuclear explosions.

NRO FOIA histories, USGS declass imagery, and NARA film holdings document KH-9 Hexagon search and KH-7/KH-8 Gambit surveillance as Cold War film-return giants—multi-bucket recovery latency and failure modes included—until electro-optical near-real-time replaced the architecture.

The Manhattan Engineer District did not invent military secrecy. It industrialized a version so tight that even other wartime science programs looked loose by comparison. When Congress wrote the Atomic Energy Act of 1946, it did not merely transfer the Army’s bomb factories to a civilian commission.

Project MINARET was NSA's formalized watch-list dissemination of Americans' international communications (~1967–1973), documented in Church Committee Book III and National Security Archive declassified histories. The Archive holds those primary doors open under documented / L1 clearance.

CIA/Air Force film-return reconnaissance satellites (1959/60–1972), publicly covered as Discoverer, resolved the missile-gap debate with overhead IMINT. President Clinton's EO 12951 (24 Feb 1995) declassified CORONA/ARGON/LANYARD imagery—one of the largest intelligence declass projects.

In 1981, French intelligence ran KGB Col. Vladimir Vetrov ('Farewell'), who supplied roughly 4,000 documents on Soviet Line X scientific-technical theft. Mitterrand briefed Reagan; CIA/NATO mounted a counterintelligence response including altered technology.

Lawrence Livermore / AEC–Air Force Project Pluto (1957–1964) built Tory nuclear ramjet reactors for a proposed Supersonic Low-Altitude Missile (SLAM). Ground tests succeeded; the flying doomsday cruise missile was cancelled.

North Korean MiG-21s shot down U.S. Navy EC-121M Deep Sea 129 on a Beggar Shadow SIGINT orbit about 80–90 nm offshore on 15 April 1969, killing all 31 crew. NSA's 1989 cryptologic history details warning failures, CRITIC reporting, and crisis response that helped drive creation of the National SIGINT Operations Center (NSOC).

NRO’s Quill (P-40) launched on 21 December 1964 as the first U.S. experimental orbital synthetic-aperture radar satellite, imaging selected U.S. targets only to validate propagation and intelligence value without foreign illumination protests. Declassified NRO histories and a 2011 lecture packet document a short, successful proof-of-concept—not an operational worldwide radar fleet.

From 1967–1972 Operation Popeye ran non-publicized cloud-seeding interdiction over Ho Chi Minh Trail corridors. FRUS Doc 274 shows State already debating weather-warfare precedent; 1974 Senate hearings forced DoD admission of thousands of sorties; ENMOD later banned hostile environmental modification.

The CIA Astro-Projection Study. The CIA secretly investigated whether humans could transcend time, space, and the physical body through altered states of consciousness.

The U.S. Navy sprayed a massive cloud of live bacteria over San Francisco to test how vulnerable a major city would be to a biological attack.
