Technical analysis nuclear weapon storage on Kleine Brogel

In this article we give an overview of the information gathered through inspection actions and from military documents on the nuclear weapon storage on the military base of Kleine Brogel.
From publicly available contract information, it is known there are 11 WS3-systems on the Belgian air force base. These systems have been used to store B-61 nuclear weapons since April 1992. source: WS3.pdf (page 7) These systems are situated in the hardened aircraft shelters (HAS), of which 26 are present on the base. From our investigation we conclude that the WS3-bunkers are spread over different parts of the base. We inspected 15 hardened aircraft shelters and found 6 with a WS3-system: 2, 8, 10, 17, 18, 21 . Another 2 WS3-systems are probably in HAS 23 and 24 on the former quick reaction area. Thanks to our inspections we have located 8 of the 11 WS3-systems to date. - From a US nuclear inspection report, we know that HAS 17 and 21 each contain a WS3-system. This report also includes references to HAS 23 and 24 on the former quick reaction area. A comparative inspection of the shelters' outside features discloses that thos aircraft shelters with a WS3-system have an extra electrical system that is visible from the outside. Based on this, we conclude that HAS 2, 8, 10, 18 contain a WS3-installation. - This observation is confirmed by the inside inspection of one of the HAS with a WS3-system. During this inspection, the following picture was taken: The WS3-system in the ground is not visible and could not be photographed without being closer to it, which would have activated the alarm system. But visible on the right is the control installation of the WS3-system. This installation is similar to one pictured in a briefing given by the US air force on the modernisation of the WS3-system: In the picture, one can see that the electrical wiring comes from the front side, where we observed the additional outside electrical wiring. From the control installation, the wiring leads into the ground towards the underground weapon storage vault. The installation is guarded by an infrared alarm system that can be seen on the roof of the bunker. According to available public information, the underground storage vault is surrounded by a 15ft-safety zone, but the Bombspotting inspection team remained at a distance in order to avoid setting off the alarm. Conclusion: - In as far as it was still necessary to prove, this information makes clear that the air force base of Kleine Brogel is an active nuclear weapons base. - The picture inside the aircraft shelter clearly reveals how close people can get to the nuclear weapons without being noticed. This does not mean you can steal a nuclear weapon without being noticed. Coming nearer would turn the alarm system on and we do not doubt that a strong intervention force would be present in a short period of time. Furthermore, removing the nuclear weapons from their underground storage vault would be no easy job either. Yet, it is clear that these nuclear weapons are far from secure. Especially when the WS3-vault is open, the nuclear weapons and the soldiers working on them are vulnerable to attacks from small arms, RPG's, or well-designed booby traps. A terrorist attack aimed at destroying nuclear weapons and resulting in the spread of nuclear material, or aimed at taking over control during maintenance work, are very well possible. - Mr President, be happy we are peace activists. It is time to turn nuclear disarmament rhetoric into deeds. Eliminate these nuclear weapons! They are no asset for our security but rather a danger.
