    This compact A-10 was one of the most commonly used sextants in the Army Air Forces. Tens of thousands were made during World War II, and many remained in service with the Air Force through the 1950s.


    Sextants were in heavy use in all branches of the US armed forces during World War II. In the case of the US Air Forces, having a means to quickly gauge the altitude of a given object, was an essential part of conducting an anti-aircraft defense and coordinating airplanes from the ground.


    A sextant is an instrument used to measure the angle between any two visible objects. Its primary use is to determine the angle between a celestial object and the horizon which is known as the altitude. Making this measurement is known as sighting the object, shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical or aeronautical chart. A common use of the sextant is to sight the sun at noon to find one's latitude. Since the sextant can be used to measure the angle between any two objects, it can be held horizontally to measure the angle between any two landmarks which will allow for calculation of a position on a chart. A sextant can also be used to measure the Lunar distance between the moon and another celestial object (e.g., star, planet) in order to determine Greenwich time.
