Open Skies Treaty was signed in

The Open Skies Treaty was signed in 1992 allowing unarmed aerial surveillance flights over participating countries to promote openness and trust. It was proposed in 1955 but finalized in Helsinki in 1992 with 34 initial signatories. The treaty entered into force in 2002 and has been used for over 1500 flights. It aims to enhance military transparency and confidence-building among nations particularly in Europe and North America. The agreement includes provisions for sensor technology and data sharing to ensure compliance. This treaty is important for international relations and arms control studies providing a framework for reducing tensions through verification measures. Update (as of 2025-09-04)
