About this route:
A direct, nonstop flight between Andersen Air Force Base (UAM), Agana, Guam and Harrison County Airport (ASL), Marshall, Texas, United States would travel a Great Circle distance of 7,396 miles (or 11,902 kilometers).
A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the large distance between Andersen Air Force Base and Harrison County Airport, the route shown on this map most likely appears curved because of this reason.
Try it at home! Get a globe and tightly lay a string between Andersen Air Force Base and Harrison County Airport. You'll see that it will travel the same route of the red line on this map!

- Andersen saw an end to its role in rotational duties when the B-47 was phased out and replaced by the B-52 Stratofortress.
- Flying out of Guam, S/Sgt Henry E Erwin of the 29th Bombardment Group was awarded the Medal of Honor for action that saved his B-29 during a mission over Koriyama, Japan, on 12 April 1945.
- The 19th Bombardment Wing was formed at North AFB in 1948 from the resources of the former North Guam Air Force Base Command.

- Andersen is one of four bomber forward operating locations in the US Air Force.
- The base returned to routine operations by the late 1970s, but continued to serve as one of SAC's strategic locations.
