National leaders praised wartime research and development efforts and agreed that peacetime R AND D was vital to the nation. After the war, organization of research changed. The Navy bureaus took over management as well as sponsoring of the laboratories. In San Diego, NRSL and UCDWR became the, Navy Electronics Laboratory (NEL). In Pasadena, the facilities previously operated as part of Caltech's wartime rocket and torpedo development work were transferred to become the NOTS Pasadena annex. NEL continued NRSL's work in ship antenna development and directivity. Efforts were directed toward minimizing the number of antennas and using ship structural elements to enhance antenna performance. NEL continued UCDWR work on radar beacons; the precision RACON system went to the Fleet in 1949. Work continued on aircraft recognition systems, which included development of the Mk X identification Friend or Foe (IFF) prototype. NEL also completed the Sound Fixing and Ranging (SOFAR) system for locating survivors at sea. And NEL's long interest in the interaction and submarines with the submerged environment led to pioneering studies of the Arctic.
