Dahlgren dahlgren00mcco Year: 1977 Chronology 13 From 1924 to 1930, special ballistics studies and investigations conducted at reduced scale were performed at Dahlgren. These studies revealed that pene- tration results were closely similar at different scales for similar conditions of test. Impressed by the results of these tests, as early as 1927 the Dahlgren Proving Ground recommended that a laboratory be built for development tests and experimental work on armor, projectile, and assorted systems at small scale. Such studies were not only vital scientifically, but the economy resulting from their performance helped maintain the R&D programs of the Proving Ground during a period of severe economic restriction in military expendi- tures. Not until 1940, however, were funds for the creation of an Armor and Projectile Laboratory allocated by the Bureau of Ordnance. From 1927 to 1935, facilities for experimental work were extremely modest. However, an Experimental Laboratory was created and expanded between 1936 and 1940, and the Plate Battery evolved as a separate department. By the beginning of the war, the Experimental Department consisted of the Adminis- tration and Technical Staff plus the Velocity Section. Technical staff supervision was assigned to the Chief Physicist who acted as the Head Technical Assistant to the Experimental Officer. All personnel in- volved in bomb calibration, exterior ballistics, velocity measurements, arma- ment tests, development work, and technical analysis of test results were in- cluded in the staff of the Experimental Officer and Chief Physicist.
