Nato aircraft in summit flypast over Newport and Cardiff
A display of 22 military aircraft from nine countries will fly over Newport and Cardiff during the Nato summit.
The RAF's Red Arrows will be joined by fighters from the USA, Canada, Denmark, France, Germany, Poland, Portugal and the Netherlands.
The flypast takes place over the summit at the Celtic Manor Resort on Friday 5 September at 09:00 BST.
People are advised to get the best view of the planes from Cardiff Bay at 08:30 BST.
In Newport, the display is expected at about 08:45 BST to the south of the city centre, over Spytty Park, Beechwood Park and Lliswerry.
A Wales Office spokesman said: "The display will represent some of the many Nato nations which have been involved in policing the air space across Europe as part of the Alliance's efforts to support and reassure its Eastern member states."
The display will be led by an RAF Typhoon flanked by two Polish Mig-29s and finished by the Red Arrows which will follow after a Voyager, the RAF's largest aircraft.
Other jets are due to include a Eurofighter and F-16 Falcons.
More than 150 heads of state and ministers will attend the summit on Thursday and Friday addressing conflicts, terrorism and cyber attacks while campaign groups are using the event to protest against military action.
