After the breakout of World War II, Zerstörergeschwader 26 (ZG 26), a Messerschmitt Bf 110 unit used in the Battle of France was assigned in May 1940.

In September 1944, Aufklärungsgruppe 123 (Scouting Group 123), equipped with Focke-Wulf Fw 189 used the airfield to monitor the advancing Allied armies moving east from France.

[1] American Army units moved into the Mendig area in early March 1945 as part of the Western Allied invasion of Germany and the airfield was attacked by Ninth Air Force B-26 Marauder medium bombers and P-47 Thunderbolt fighter-bombers to deny the retreating German forces use of the facility.

On 17 March, the airfield was declared ready for Allied use and was designated as Advanced Landing Ground "Y-62 Niedermendig".

When the 36th moved out on 8 April, Niedermendig was used for combat resupply and casualty evacuation by C-47 Skytrain transports until the end of the war in May.

It is home to an aeroclub Sportfluggruppe Mendig e.V., and serves as the setting for several automobile-related television and film recordings, examples are DSF-Motor, Kabel 1 - Abenteuer Auto, RTL2 - Grip, VOX Automobil or SWR Rasthaus.
