Red Beard (nuclear weapon)

Red Beard was the codename for a planned series of British thermonuclear weapons, specifically a family of hydrogen bombs. Development began in the early 1960s as part of the United Kingdom's independent nuclear deterrent program. Unlike some other British nuclear weapons programs that utilized designs directly based on US technology, Red Beard represented an independent British design effort. The specifics of the weapon's yield and design are largely classified, although it is understood that it was intended to be a significantly more powerful weapon than the preceding Blue Danube series. While the program was successfully developed to the point of testing, the final Red Beard devices were never deployed operationally, as advancements in other nuclear warhead technologies rendered them less strategically relevant by the time they were ready. The exact reasons for their non-deployment remain classified and subject to ongoing debate amongst historians of the Cold War. Further details regarding the specifics of the Red Beard design, testing procedures, and ultimately, the reasons for its non-deployment remain largely unavailable to the public due to the ongoing classification of the project.
