1 Naval Research Laboratory The Navy and Marine Corps Corporate Laboratory

2 Establishment of NRL A WORLD-CLASS LABORATORY Idea followed the sinking of the Lusitania in 1915 Secretary Josephus Daniels Established Naval Consulting Board with Edison Chair, meeting October 7, 1915 August 29, 1916 Congress appropriates funds to establish the Lab THOMAS A. EDISON GOVERNMENT SHOULD MAINTAIN A GREAT RESEARCH LABORATORY TO DEVELOP GUNS, NEW EXPLOSIVES AND ALL THE TECHNIQUE OF MILITARY AND NAVAL PROGRESSION WITHOUT ANY VAST EXPENSE. THOMAS A. EDISON, THE NEW YORK TIMES MAGAZINE SUNDAY, MAY 30, 1915 Delayed by WW-I, Assistant Secretary of the Navy, Theodore Roosevelt, Jr. Commissions the Lab at Bellevue site on July 2, 1923 Navy and Marine Corps Corporate Laboratory

3 NRL Mission Naval Research Laboratory To conduct a broadly based multidisciplinary program of scientific research and advanced technological development directed toward maritime applications of new and improved materials, techniques, equipment, systems and ocean, atmospheric, and space sciences and related technologies. Primary in-house research for the physical, engineering, space, and environmental sciences Broadly based applied research and advanced technology development program in response to identified and anticipated Navy and Marine Corps needs Broad multidisciplinary support to the Naval Warfare Centers Space & space systems technology development & support Designated as the Navy's corporate laboratory by SECNAV 1991

5 Remote Sensing Division: Crabs to the Crab Nebula Navy center of excellence for environmental remote sensing research and development, conducting a broad program of basic and applied research across the full electromagnetic spectrum using active and passive techniques from ground-, air-, and space-based platforms. Includes both remote sensing technology and phenomenological expertise. Emphasizes an interdisciplinary approach to remote sensing challenges. Present research areas include astrophysics, ionospheric, atmospheric, earth, and ocean science.
