From Allied Command Operations: [A]fter three years of negotiations, Finland and three Baltic nations have agreed to sign a Memorandum of Understanding, establishing an Air Situation Data Exchange.
Up to now, four operational "Air Situation Data Exchange” (ASDE) connections have been implemented in accordance with the ASDE program, i.e. between Germany and Austria, Hungary and Ukraine, Turkey and Georgia and Finland, and today between Finland the three Baltic states, Estonia, Latvia and Lithuania. All four ASDE connections have been assessed as operational and no principal problems were reported. (photo: Allied Command Operations)
