United States conducts nuclear test shot "Zuni" as part of Operation Redwing nuclear tests at the Pacific Proving Grounds. Bright flash appears due to the Zuni shot bomb blast, the first ever of a three-stage thermonuclear design. Huge fireball boils upward into the sky. Spots of fire in sky as darkness spreads. Zuni was a 3.5 Megaton Hydrogen bomb with 85% of its yield from fusion. This was a companion test to the "dirty" (87% fission) Tewa shot using the same bomb design.
Full-scale thermonuclear test of ultracold liquid deuterium, codenamed MIKE at Enewetak Atoll in the Pacific Proving Ground in the Marshall Islands (sometimes spelled Eniwetok or Eniewetok). (Left to right) Chief engineering and firing commander, Stan Burris -- later the leader of the Strategic Ballistic Missile development, including Polaris and later editions; retired as CEO of Rockwell Aerospace -- military firing and security commander, Colonel Richard Lunger, and ultracold refrigeration engineering commander for thermonuclear liquid fuel state monitoring, Robert Gibney. The intense nuclear radiation ignited the atmosphere around the device, creating a fireball 4.2 miles across. A remote firing control was created, using a televison tower beam signal to safely trigger the detonation from the USS Estes, approximately 35 miles south/southeast of the detonation. White hot device remnant specks are visible throughout the surface of the fireball. Shockwave from explosion is seen spreading across the water, then a white mushroom cloud spreading above. View of crew on ship deck observing blast. Device yield: 10.4 megatons.
A training film titled 'The Kwajalein Operations' on the operations of U.S. forces on Kwajalein Atoll in the Marshall Islands during World War II. A map locates islands in the Pacific Ocean. Animation depicts the area invaded by U.S. forces. The Gilbert Islands, the Solomon Islands, Midway Island, Tarawa and other islands located on the map. U.S. lines of communication on various islands. Kwajalein Atoll on the map. The atoll is selected as a base for U.S. forces. It is selected because of various benefits which would prove useful during the invasion of the Marshall Islands. Bases and installations on Kwajalein Atoll.
George C. Marshall, U.S. Army Chief of Staff, stands on the top step of a wood and woven palm building, headquarters of the U.S. 6th Army, on Goodenough Island, New Guinea, during World War 2. Lieutenant General George C. Kenney, Commander of Allied Air Forces and the U.S. Fifth Air Force, stands with two other officers on the ground in front of the hut. General Douglas MacArthur Supreme Commander of Allied Forces in the Southwest Pacific Area (SWPA) joins Marshall and poses, standing to his left. General Marshall leaves the building to enter a car. Next, he is seen standing on the ramp of an airfield. MacArthur is also seen briefly, standing next to Marshall. General Marshall converses with Lieutenant General Walter Kreuger, Commander of the Sixth United States Army in the South West Pacific Area, and with General Kenney. General MacArthur and General Kenney, followed by other officers, walk back from a B-17 bomber (General Marshall's airplane) after saying goodbye to General Marshall. General Kreuger remains at the door of Marshall's B-17, bidding Marshall farewell. The B-17 is next seen taking off from the runway.
First air drop test of a thermonuclear weapon. The weapon was dropped from a USAF B-52 bomber (not seen) that flew from Fred Island, Eniwetak (sometimes spelled Enewetak or Eniewetok), on May 21, 1956. View appears to be from an aircraft flying above altocumulus clouds, below higher stratiform layers. The film begins with a complete whiteout from the initial fireball. As that subsides, local stratiform clouds take on a rosy hue and the center fireball is seen rising above them. As the fireball rises, it takes on a somewhat hemispherical shape, flat on the bottom, from which a straight stem-like column extends toward the ground. The light of the explosion slowly fades and complete darkness ensues. Official accounts state that the intended ground zero was directly over Namu Island, but the flight crew mistook an observation facility on a different island for their targeting beacon with the result that the weapon delivery was grossly in error. The bomb detonated some 4 miles off target over the ocean northeast of Namu. As a result essentially all of the weapons effects data was lost. ( Note: According to ancillary reports, the delivery error resulted in blast overpressures and thermal effects on the 6 structural response targets between Iroij and Namu Islands, greatly exceeding specifications for any use in scientific military modeling of high yield aerial detonations. Plans for graded damages analysis failed when all the structures collapsed. Effects cameras also failed from the intense fireball heat.)
