BERLIN/WASHINGTON (Own report) – The modernization of nuclear weapons – already possessed by nine countries, and affecting Germany through “nuclear sharing” – is rapidly progressing, according to a current analysis of the Stockholm International Peace Research Institute (SIPRI). The overall number of nuclear weapons in the world has slightly decreased SIPRI notes. However, new US-bombs (B61-12), for example, are much more precise than their predecessor models. Experts warn that this development could lower the threshold for their possible use. The B61-12 bombs are likely to be stationed also at the German Air Base in Büchel in the hills of the Eifel. Germany’s “nuclear sharing” status has already prompted discussions in the arms industry. Airbus has begun to design a successor model to the tornado jet fighter, which is currently certified for the B61. If this next generation jet fighter is to be certified also for the US bomb, all its construction details would have to be revealed to the USA, a prospect being met with misgivings in the Berlin establishment. It has recently been reported that the URENCO nuclear fuel company, which also has a plant in Gronau (North Rhine-Westphalia) has agreed to supply enriched uranium to a US power plant that produces tritium for US nuclear weapons.
