Because of difficulties experienced in landing range parties in winter, additional stations were added on the Mary- land ^ As a result of adverse weather conditions in 1933, five Virginia stations were added in 1936. Since then, all range activities have been conducted from the Virginia stations. Until after World War 11, four lighthouses were used for range stations: Cobb Point Bar, Blackistone Island, Ragged Point, and Piney Yardcraft range vessels manned by enlisted naval personnel assisted in range activities from October 16, 1918, when the first range boat, MURRAY, a Maryland Conservation Commission boat procured by the Proving Ground, landed the first range party. The complement of range vessels in 1922 consisted of two subchasers, a 40-foot motor sailer, a gig, and a large launch. Additional range vessels were not obtained until World War II.^^ The nucleus of Dahlgren's future research and development (R&D) facilities lay in the Experimental Department. Since the establishment of the Proving Ground, an Experimental Officer had been among its group of officers and was in charge of the Plate Battery, experimental testing, and velocity readings.^^.
