Mark 7 nuclear bomb

Mark 7 "Thor" was the first tactical fission bomb adopted by US armed forces. It was the first weapon to be delivered using the toss method with the help of the low-altitude bombing system; the weapon was tested in Operation Buster-Jangle. To facilitate external carry by fighter-bomber aircraft, Mark 7 was fitted with retractable stabilizer fins; the Mark 7 warhead formed the basis of the 30.5 inches BOAR rocket, the Mark 90 Betty nuclear depth charge, MGR-1 Honest John rocket, MGM-5 Corporal ballistic missile. It was supplied for delivery by Royal Air Force Canberra aircraft assigned to NATO in Germany under the command of SACEUR; this was done under the auspices of Project E, an agreement between the United States and the UK on the RAF carriage of US nuclear weapons. In UK use it was designated 1,650 lb. H. E. M. C; the Mark 7 was in service from 1952 to 1967 with 1700–1800 having been built. The Mark 7 was a variable yield fission weapon using a levitated pit and an implosion design using 92 high explosive lenses.

The weapon had multiple yields of 8, 19, 22, 30, 31, 61 kt by using different weapon pits. The weapon had both an contact fuzing modes; the weapon used in flight insertion for safing and versions of the weapon used a PAL A type arming and safing system. 1700 to 1800 Mark 7 bombs and 1350 W7 warheads were produced. The Mark 7 nuclear weapon weighed 1,600 pounds, it was fitted with one vertical retractable stabilizer fin that allowed it to fit better in or under some planes. This was unique, made it one of the first nuclear weapons to be streamlined enough to be carried on smaller planes; the bomb’s diameter is a total of 30 inches. There were 10 different mods of this warhead produced for several different delivery systems. Beside the Mark 7 bomb, this included the BOAR air-to-surface rocket, the MGR-1 Honest John and MGM-5 Corporal tactical surface-to-surface missiles, the Betty Mark 90 depth bomb, the MIM-14 Nike Hercules surface-to-air missile and an atomic demolition munition. Configured as a Mark 7 gravity bomb and as the BOAR, the weapon was carried by the F-84 Thunderjet, F-100 Super Sabre and F-101 Voodoo fighter-bombers, the B-57 Canberra bomber.

During Operation Teapot MET on 15 April 1955 a test was conducted using a Mk7 warhead using an experimental composite plutonium/uranium-233 pit, producing a 22kt yield, 33% lower than expected. As Shot MET was a military effects test the lower yield ruined many of the experiments being conducted by the DoD during the test; the DoD had not been informed of the substitution by Los Alamos. The June 4, 1953 "Climax" test in Operation-Knothole was a boosted Mark 7 dropped by a B-36 aircraft and detonated with a yield of 60 kilotons. </ref> A Mark 7 casing is on display in the Cold War hangar at the National Museum of the United States Air Force in Dayton, Ohio.

Xbox One

The Xbox One is an eighth-generation home video game console developed by Microsoft. Announced in May 2013, it is the successor to Xbox 360 and the third console in the Xbox series of video game consoles, it was first released in North America, parts of Europe and South America in November 2013, in Japan and other European countries in September 2014. It is the first Xbox game console to be released in China in the Shanghai Free-Trade Zone. Microsoft marketed the device as an "all-in-one entertainment system", hence the name'Xbox One'; the Xbox One competes against Sony's PlayStation 4 and Nintendo's Wii U and Switch. Moving away from its predecessor's PowerPC-based architecture, the Xbox One marks a shift back to the x86 architecture used in the original Xbox. Xbox One's controller was redesigned over the Xbox 360's, with a redesigned body, D-pad, triggers capable of delivering directional haptic feedback; the console places an increased emphasis on cloud computing, as well as social networking features, the ability to record and share video clips or screenshots from gameplay, or live-stream directly to streaming services such as Mixer and Twitch.

Games can be played off-console via a local area network on supported Windows 10 devices. The console can play Blu-ray Disc, overlay live television programming from an existing set-top box or a digital tuner for digital terrestrial television with an enhanced program guide; the console optionally included a redesigned Kinect sensor, marketed as the "Kinect 2.0", providing improved motion tracking and voice recognition. The Xbox One received positive reviews for its refined controller design, multimedia features, voice navigation, its quieter and cooler design was praised for making the console more reliable than its predecessor on-launch, but the console was criticized for running games at a technically lower graphical level than the PlayStation 4. Its original user interface was panned for being nonintuitive, although changes made to it and other aspects of the console's software post-launch received a positive reception, its Kinect received praise for its improved motion-tracking accuracy, its face recognition logins, its voice commands.

The original Xbox One model was succeeded by the Xbox One S in 2016, which has a smaller form factor and support for HDR10 high-dynamic-range video, as well as support for 4K video playback and upscaling of games from 1080p to 4K. It was praised for its smaller size, its on-screen visual improvements, its lack of an external power supply, but its regressions such as the lack of a native Kinect port were noted. A high-end model, named Xbox One X, was released in November, it will be succeeded by the upcoming Xbox Series X consoles in Holiday 2020. The Xbox One is the successor to Xbox 360, Microsoft's previous video game console, introduced in 2005 as part of the seventh generation of video game consoles. Over the years, the 360 had received a number of small hardware revisions to reduce the unit's size and improve its reliability. In 2010, Microsoft's Chris Lewis stated. Initial hardware for the 360's successor referred to by the industry as the "Xbox 720", was under development as early as May 2011.

The official developer kit was codenamed Durango, appeared to be available to developers by mid-2012. Leaked documents suggested that the new console would include an improved Kinect sensor, cloud access to games and media, integration with phone and tablet devices, technology to provide players heads-up displays on glasses worn by the player, codenamed "Fortaleza". Leaked design documents suggested that Microsoft was seeking to eliminate the ability to play used games, though Microsoft clarified it was still reviewing the design and were "thinking about what is next and how we can push the boundaries of technology like we did with Kinect", but did not comment on the validity of the information. Prior to the official unveiling, rumors had circulated that the next Xbox console would be an "always on" system requiring a persistent Internet connection, though Microsoft had not confirmed this; this had drawn some concerns from consumers, which were heightened when Microsoft Studios employee Adam Orth stated in a Twitter message in April 2013 that said "Sorry, I don't get the drama around having an'always on' console...

Every device now is'always on.' That's the world. #dealwithit". Orth's message drew further ire towards Microsoft, with concerns about digital rights management and practices against the sale of used games with an "always on" unit. Orth opted to leave Microsoft a few days due to the backlash. Despite Microsoft's statements following the situation, denying the rumors, the mood it created lingered over the next several months; the new console was publicly unveiled under the name Xbox One on May 21, 2013 in a press conference that presented the unit as an all-in-one home entertainment device. The event focused on the device's multimedia capabilities, demonstrating integration with television for over 30 minutes before any video games were shown. In a 2019 interview Phil Spencer, head of Xbox at Microsoft, recalled that not only did this approach confuse consumers about the intent of the Xbox One, but Microsoft employees, working on the console. Spencer stated that several e
