==History==

During the [[Cold War]]
The standard system had functioned since the late 1940s, but was unsatisfactory for overseas duty in multiple regards: primarily, it required the weapons be kept mounted on the body of the alert aircraft to ensure they could take off quickly enough when called (despite aircraft not being designed to safely or securely store nuclear weapons). Secondarily, it also posed an [[OPSEC]] risk, as any large amount of activity around the weapons bunkers during a time of crisis would be quickly spotted by the Soviets and interpreted as a prelude to nuclear attack. Lastly, there was a serious risk that wartime damage to airbases from a [[Pre-emptive war|first strike]] using nuclear [[airburst]] or [[Chemical_warfare#Persistency|persistent chemical weapons]] attack would deny access to the bunkers for many weeks without actually destroying them, thus creating a much-feared "soft kill" scenario in which most of NATO's [[theater (warfare)|theater-based]] nuclear assets could be rapidly neutralized by a much smaller number of Soviet "soft" [[area denial]] strikes. In a projected multi-day war, this was feared to be a decisive handicap.
The WS3 system consists of a Weapons Storage Vault (WSV) and electronic monitoring and control systems. One vault can hold up to four [[nuclear weapon]]s and in the lowered position provides ballistic protection through its hardened lid and reinforced sidewalls.<ref name=Nuclear-Matters /> The WS3 system allowed storage directly underneath the aircraft intended to carry the bombs. The ___location inside the aircraft shelter increased the weapon survivability in case of any kind of attack and prevented monitoring of preparations to use the weapons. The electronic systems include various classified sensors, electronic data-transmission and security equipment such as video, motion detectors, closed circuit TV coupled with thermal imaging devices. These facilities enabled remote controlled weapon safety and made the large security forces obsolete.▼
Deployment of the WS3 system was authorized in 1988,<ref name=chronology /> and they were in widespread use by 1995.

The electronic systems include various classified sensors, along with electronic data-transmission and security equipment such as video, motion detectors, closed circuit TV and thermal imaging devices, thus making the WS3 shelters more secure against [[sabotage]] and infiltration compared to existing igloo-style bunkers.
==Deployment==
215 WS3 vaults were built for the [[United States Air Forces in Europe]] at 13 sites in seven countries. Additionally 34 WS3 vaults were built for the [[Royal Air Force]] to store the [[WE.177]] nuclear bomb; 10 at [[RAF Brüggen]] in Germany and 24 at [[RAF Marham]] in Britain.<ref>{{citation|url=http://thebulletin.metapress.com/content/82558p4j65585158/fulltext.pdf|title=U.S. nuclear weapons in Europe, 1954–2004|author=Robert S.
