In 1939 the word 'navigation' usually carried the modifier 'celestial', for it was by observing the stars that sailors and more recently airmen had found their way. It was the absence of a clock that would run accurately aboard a rolling, generally damp and uncomfortable ship that led to countless vessels breaking up on unexpected rocks. The substantial prize for a practical means of determining longitude had not been intended for a practical man, however; the Board had had an astronomer in mind, and Harrison waited ten years to receive his reward [ 1 ].
Eight machinegun batteries were credited with having downed 41 . The Coast Artillery pressed for modern equipment and secured from the Ordnance Department in 1925 a satisfactory plan, which came to nought because of the budget restrictions of the 1930s. The Coast Artillery School at Fort Monroe emphasized technical quality. As part of a general strengthening of the arm a 37 mm automatic gun, which had been under development for more than a decade, was to replace machine guns . 50 inch machine guns for close defense was rejected for the 40 mm Bofors and the 20 mm Oerlikon .
This led to the organization of heavy machine gun battalions in the fall of 1938 that were armed with the 20 mm automatic gun and under Army control. When war broke out in the summer of 1939 Germany had far and away the most advanced antiaircraft force of any nation, with 107 000 men on the rolls [7 ]. Experience with Curtiss JN2s in the expedition to Mexico in 1916 'indicated that airplanes had a sufficient tendency to fall unaided out of the sky' so that an air defense arm hardly seemed to be urgent, but the nature of the war in Europe quickly dispelled such ideas [8 ].
