The Open Skies Consultative Commission (OSCC) is the implementing body for the Open Skies Treaty. It consists of representatives from each of the 34 States Parties to the Open Skies Treaty. The Open Skies Treaty entered into force in January 2002, and covers territory from Vancouver to Vladivostock. The Treaty establishes a regime of unarmed aerial observation flights over the entire territory of its 34 signatories. It is designed to enhance mutual understanding and confidence by giving all participants, regardless of size, the possibility to obtain information on military or other activities of concern to them. Open Skies is the most wide-ranging international effort to date to promote openness and transparency of military forces and their activities.
