HARDTACK-Teak was an exoatmospheric high altitude nuclear weapon test performed during Operation Newsreel. It was launched from Johnston Atoll on a Redstone missile. On 1 August 1958, the 3.88 Mt (16.2 PJ) shot detonated at an altitude of 76.8 km (252,000 ft; 47.7 mi) . In 1993, Congress appropriated no funds for the Johnston Atoll Safeguard C mission, bringing it to an end. Anti-satellite mission 1962-197
Operation Dominic. Operation Dominic was a series of 31 nuclear test explosions with a 38.1 Mt (159 PJ) total yield conducted in 1962 by the United States in the Pacific. This test series was scheduled quickly, in order to respond in kind to the Soviet resumption of testing after the tacit 1958-1961 test moratorium These nuclear testing operations culminated with the Cuban Missile Crisis, and reached the fiercest point the day of the Bluegill Triple Prime test of near 1 megaton was detonated. During the night of that same day (local Washington, DC time) of October 26, U.S. Attorney General Robert Kennedy met secretly with Soviet Ambassador Anatoly Dobrynin to make emergency negotiations at the Soviet embassy in Washington, DC The successful rocket-launched, weapons-effects, Operation Fishbowl high-altitude tests conducted in the Johnston Island area in 1962 were as follows: STARFISH PRIME, July 9, 400-kilometer. Less well known are the US nuclear tests on Johnston Atoll in 1962. Johnston Atoll is located between the Marshall Islands and Hawai'i, and is known to the Kanaka Maoli people as Kalama Island. The island was claimed for the Kingdom of Hawai'i in July 1858, with the support of King Kamehameha Between 1958 and 1975, Johnston Atoll area was used as an American national nuclear test site for atmospheric and high-altitude nuclear explosions. In 1958 Johnston Atoll participated in the Hardtack I nuclear test. The U.S. military used Johnston atoll for two nuclear tests during the series

Access to the atoll is via ocean vessel. As the only shallow water and dry land area in 450,000 square miles of ocean, Johnston Atoll is an oasis for reef and bird life In 1995 the U.S. government declassified a set of military documents which outlined the real story behind a series of failed high-altitude nuclear tests and atmospheric air drops during 1962 on a tiny atoll in the middle of the Pacific called Johnston Island Beyond the 1962 nuclear tests, Johnston Atoll was used to store chemical weapons from Okinawa after 1970 and drums of Agent Orange defoliant from the Vietnam War in 1972. Throughout the 1990s, the island was also the site for the Johnston Atoll Chemical Agents Disposal System (JACADS), an incineration plant for chemical weapons removed from Okinawa and Germany following the end of the Cold War
Johnston Island (also referred to as Johnston Atoll) is a decommissioned US Naval base 800 miles west of Hawaii. During the 1960s and 70s, it was the site of numerous high altitude nuclear test launches, including Operation Dominic, in which plutonium was scattered across the island from one of the failed Thor rockets Starfish Prime was a high-altitude nuclear test conducted by the United States, a joint effort of the Atomic Energy Commission (AEC) and the Defense Atomic Support Agency.It was launched from Johnston Atoll on July 9, 1962, and was the largest nuclear test conducted in outer space, and one of five conducted by the US in space The Johnston atoll was turned into a chemical and nuclear weapons dump in 1986, when the military planned and implemented the Johnston Chemical Agent Disposal System (JACADS). As part of this plan, radioactive waste and chemical weapons such as Agent Orange (leftovers from the Vietnam War) were burned to dispose of them, and leftovers dumped into a 25 acre area on the atoll VP-6 crews at Johnston Atoll during the Operation Dominic nuclear tests in 1962 I flew with Captain Leonard, Crew One 1961 and 1962.

The island was named for Captain James Johnston who claimed its official discovery on December 10, 1807.The Johnston Atoll was claimed by both the United States and the Kingdom of Hawaii in 1858.The Atoll's guano deposits, mined by U.S. interests operating under the Guano Islands Act, were worked until depletion at about 1890 Johnston Atoll was contaminated with transuranic elements, particularly plutonium, by atmospheric nuclear weapons tests and aborted nuclear devices. Initial cleanup operations and and an extensive soil remediation program were performed. However, many areas contained a low-level continuum of activity, and subsurface contamination has been detected Operation HARDTACK I consisted of 35 nuclear tests conducted at the Pacific Proving Ground between April 28 and August 18, 1958. These tests included balloon, surface, barge, underwater, and rocket-borne high-altitude tests. The first test, Yucca, was a nuclear device attached to a helium balloon launched from the USS Boxer near Enewetak Atoll
