The A340 is an airliner used for civilian transport. It made its first appearance in Ace Combat: Assault Horizon and later appeared in Ace Combat 7: Skies Unknown, specifically in missions involving Selatapura.
The A340 appeares to be a popular choice among airline corporations in Strangereal, evident in its use by airlines by various flag carriers across the globe. By the 2010s, at least three airlines were known to have used the aircraft, including Osea Airlines, Emmeria Airways, and Air Erusea.
During the Lighthouse War, multiple A340s owned by Osea Airlines, Emmeria Airways, and Air Erusea, were parked at Selatapura's international airport. A340s from those three airlines continued using the airport during Operation Lighthouse Keeper, Operation Daredevil, and Operation Hush.

During the battle over Dubai, AWACS Magic informs Warwolf Squadron that an A340 carrying cargo and supplies is flying through the airspace. The A340 later almost collided with William Bishop's aircraft as he chased an enemy ace pilot. The A340 soon after flew down a river in northern Dubai towards Dubai International Airport, landing on the central runway after reaching its destination. 
In the final battle of the New Russian Federation uprising, another A340 takes off from Ronald Reagan National Airport. Multiple other A340s also remained parked at the airport during the Washington, D.C. battle.
