Location
Lat 9° 23' 49N Long 167° 28' 15E  Roi Airfield is located on the western portion of Roi Island in Kwajalein Atoll in the Marshall Islands. During late 1944 during the U.S. occupation, fill was added between Roi Island and Namur Island, forming Roi-Namur Island. Today known as Dyess Army Air Field (Dyess AAF) or Freeflight International Airport.

Construction
In 1914, Japan occupied the Marshall Islands and built Roi Airfield with three intersecting runways: Runway A (running roughly north-east to south-west), Runway B (running roughly north-west to south-east) and Runway C (running roughly east to west). An apron and limited taxiways were located at the base parallel to the runways. Two hangers were constructed on the eastern side of the runways. Defended by light and heavy anti-aircraft guns.

Wartime History
On December 8, 1941 at the start of the Pacific War, Japanese bombers from Roi Airfield bomb Wake Island. Starting in late 1943 targeted by American aircraft ahead of Operation Flintlock to capture Kwajalein Atoll.
