The governments of Estonia, Latvia and Lithuania signed a declaration of cooperation on transboundary airspace on the sidelines of the North Atlantic Treaty Organization (NATO) summit in Vilnius, Lithuania. The event began yesterday 11 July and ends today 12 July 2023. The aim is to strengthen the posture of deterrence and defense in allied territory, in a delicate moment due to the Russian military aggression against Ukraine. 

Relevant Allied civil and military authorities will establish and utilize adequate volumes of airspace for NATO training and exercises and other air activities in the Baltic region. The ability of the Atlantic Alliance to train its men and women on a large scale in the air domain is in fact an essential element, as demonstrated by the recent "Air Defender 23" exercise, which brought together 10,000 soldiers and 250 aircraft (100 of which from the United States) from 25 countries. 

At the heart of the cooperation between the Atlantic Alliance and civilian partners are the proven relationships built within the NATO Aviation Committee, whose mandate is to support the Alliance's efforts to continue to adapt to the context of rapidly evolving safety in an increasingly complex and interconnected airspace.
