Watch from Eindhoven as Nato secretary-general Jens Stoltenberg and others unveil a new air tanker fleet.
EU commissioner Thierry Breton and Dutch defence minister Kajsa Ollongren will also make speeches at the launch event in The Netherlands.
The ceremony marking the initial operational capability of the new Multinational Multi-Role Tanker Transport aircraft fleet is taking place at the PAX Terminal of Eindhoven Air Base.
Nato says the fleet is an important example of NATO-European Union cooperation.
It will "perform key functions such as air-to-air refueling, air transport and medical evacuation," according to Nato.
