Pictured is an Officer of the watch aboard HMS Vanguard. The Royal Navy has operated the UK’s Continuous at Sea Deterrent since 1967 when the first SSBN – or Ship Submersible Ballistic Nuclear – HMS Resolution began patrolling armed with the Polaris missile system. In 1996 HMS Vanguard, the first submarine armed with the Trident missile system, arrived on the Clyde and took over deterrent patrol duties from the Resolution Class.
The four Vanguard-class submarines form the UK's strategic nuclear deterrent force. Each of the four boats are armed with Trident 2 D5 nuclear missiles. Like all submarines the Vanguard Class are steam powered, their reactors converting water into steam to drive the engines and generate electricity.

TRINITY PHOTOGRAPH - Alamogordo, NM - Trinity Test, July 16, 1945 - Vital Components are loaded at the old McDonald Ranch for the trip to the Trinity test site.
Arming plugs for a 'Little Boy' type atomic bomb on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center. The plugs were found in the navigator's compartment in the B-29 bomber Enola Gay. The green plug may have been used in the bomb which was dropped on Hiroshima. The plug on the right is probably a spare.
This operation conducted at the Nevada Test Site consisted of 11 atmospheric tests. There were three airdrops, seven tower tests, and one airburst. This operation involved the testing of new theories, using both fission and fusion devices

Shift change at the Y-12 uranium enrichment facility in Oak Ridge, Tennessee, during the Manhattan Project. Notice the billboard: "Make CEW count — Continue to protect project information."
In September 1945, many participants returned to the Trinity Test site for news crews. Here Oppenheimer and Groves examine the remains of one the bases of the steel test tower.
Looking at the front of the McDonald-Schmidt Ranch House. The concrete box in front of the stone wall is the remnant of a time capsule buried in 1984 when the house was restored. The time capsule was opened in Oct 2009.
The ranch was used for assembling Gadget's plutonium core.
The Grapple-Orange Herald atmospheric nuclear test of 31 May 1957 on Malden Island, reported by Universal International Newsreel as "British H-Bomb Fired As Debate On Atom Test Ban Rages" on 3 June 1957. It was claimed at the time to be the first British test of a H-bomb. It was later revealed to be a fusion boosted fission nuclear weapon test, where the fusion boosting failed to increase the yield. It still yielding 720 kT of explosive power, probably the largest A-bomb test ever.

Calutron operators at their panels, in the Y-12 plant at Oak Ridge, Tennessee during World War II. The calutrons were used to refine uranium ore into fissile material. During the Manhattan Project effort to construct an atomic explosive, workers toiled in secrecy, most having no idea to what end their labors were directed. Gladys Owens, the woman seated in the foreground, didn't understand the exact purpose of her job until seeing this photo in a public tour of the facility fifty years later.
"TRINITY PHOTOGRAPH - Alamogordo, NM - Trinity test, July 16, 1945 - "JUMBO," a 120-ton steel vessel, was designed to contain the explosion of the bomb's high explosive and permit recovery of the active material in case on nuclear failure." (was not used for this purpose during test)
