There are a number of Pershing missile displays of inert missiles in the U.S, Germany and Russia. The Pershing systems were eliminated after the ratification of the Intermediate-Range Nuclear Forces Treaty on 27 May 1988. The treaty allowed for a total of fifteen Pershing II and GLCM missiles for display and seven Pershing IIs were retained. A number of Pershing 1 and Pershing 1a missiles are also on display.
