Open Skies Treaty

The Open Skies Treaty is one of the few remaining arms control mechanisms between Vancouver and Vladivostok. Since 2002, the unique agreement permits 34 states to conduct unarmed observation flights over other member states’ entire territories. The main objective is to be able to observe military changes. The treaty particularly promotes military transparency and confidence building between states. Representatives of the observed state can be on board of the observing aircraft. States can request all images that are collected during overflights of other treaty members. Since fall 2019, the U.S. administration under President Trump considers withdrawing from the treaty. The outcome is still uncertain. European member states support the continuation of the treaty. 

Alexander Graef and Moritz Kütt are currently working on the Open Skies Treaty. Members of the U.S.-German-Russian Deep Cuts Commission analyze the agreement, too.
