Specific topics include the movement of the big guns from Indian Head, MD to Dahlgren, VA, via barge, firing guns, newly constructed buildings at Dahlgren (administration, work, quarters, etc.), cameras (Mk. II Triangulation Camera and 33mm Universal Movie Camera No. 1884) that were used to test ship’s guns and mounts ( 1912), aerials of the base, armor plate firing (an interesting photo that includes both staff and laborer’s names), testing railroad mounts, flight control and plane testing, and bomb testing. Interior building photos show the development and usage of new computational devices (computers). Ground-breaking early computers were sent to Dahlgren to help with ballistic work and other directives, including the Aiken Relay Calculator (1946), Aiken-Dahlgren Electronic Calculator (1949), and the Naval Ordnance Research Calculator (NORC) (1955). The 1959 Universal Data Transcriber was developed to transform the data recorded from various media to the media of the calculator. Photographs show the testing of explosives in the Potomac River (1946) prior to the Bikini Tests.
