Northrop Grumman B-21 Raider
The Northrop Grumman B-21 Raider is an American strategic bomber under development for the United States Air Force (USAF) by Northrop Grumman. As part of the Long Range Strike Bomber (LRS-B) program, it is to be a long-range, stealth intercontinental strategic bomber for the USAF, able to deliver conventional and thermonuclear weapons. The Air Force is planning to replace the Rockwell B-1 Lancer and Northrop Grumman B-2 Spirit with the B-21 by 2040, and could possibly replace the Boeing B-52 Stratofortress after that. The Air Force began planning for the B-21 in 2011 and awarded the major development contract in 2015. The B-21 is expected to make its first flight in 2023 and enter service by 2027. Many aspects of the B-21 program are highly classified; the program is designated as a special access program. The Congressional Research Service noted in 2021 that the B-21's technical details and specifications, such as speed, enabling systems, "size, required stealth, struc ...

Dungeness Nuclear Power Stations
The Dungeness nuclear power stations are a pair of non-operational nuclear power stations located on the Dungeness headland in the south of Kent, England. Dungeness A is a legacy Magnox power station consisting of two 250 MWe reactors which were connected to the National Grid in 1965 and reached its end of life in 2006. Dungeness B is an advanced gas-cooled reactor (AGR) power station consisting of two 520 MWe reactors, which began operation in 1983 and 1985. They were the first in a series of AGR reactors to be constructed across the UK. In March 2009, unexpected problems discovered during a maintenance shutdown on unit B21 resulted in the reactor remaining offline for nearly 18 months. In 2015 the plant received upgrades and was given a second ten-year life extension to 2028. In September 2018, as both units were shut down for a scheduled maintenance outage, EDF encountered "significant and ongoing technical challenges" which ultimatly lead to the anouncment of its cl ...

Burroughs B20
The B20 is a line of microcomputers from Burroughs Corporation. The systems, introduced in May 1982, consist of two models: the B21 and the B22. The B21 models are rebadged Convergent Technologies AWS workstations incorporating an Intel 8086 CPU. The B22 models are rebadged IWS workstations. They run the BTOS operating system, which is a version of Convergent's CTOS, as well as CP/M and MS-DOS. Systems support up to 640 KB of RAM. The B22 included a mass storage unit with a capacity of up to 60 MB. The Burroughs B25, a rebadged Convergent NGEN system with an Intel 80186 CPU, was introduced in 1983. The B26 was introduced in 1984, and a B28 system followed in 1985 based on the Intel 80286 The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982.
