330-PS-137 (USN 707627):  Navy to Dedicate new Environmental Test Laboratory.   A new installation to be known as the Ordnance Environmental Laboratory will be dedicated at the White Oak, Maryland, Naval Ordnance Laboratory March 23, 1950.   While it is expected to make great savings in time, energy, and money, this new facility will devote its efforts to scientific destruction of weapons and weapon components for the Navy’s Bureau of Ordnance by testing within the laboratory rather than in the field.  Depicted above is Robert C. Roche, Mechanical Engineer, testing a parachute mine on a vibration testing machine in the laboratory.   Among these facilities in the environmental facility are a deep-sea pressure tank, a 100 foot air gun, which can simulate the impact of a torpedo striking a ship, a vibration laboratory, atmospheric simulation chambers, depth charge and mine testing equipment.  Scientists can, within the laboratory, subject new weapons to any combination of air and ocean conditions in the world.   Photograph released March 18, 1950.   (8/18/2015).
