This document provides a history of the Limited Duty Officer (LDO) and Chief Warrant Officer (CWO) programs in the U.S. Navy from their origins to modern times. It describes how the programs have evolved over centuries from their roots in warrant officers who served specialized technical roles, through various expansions and contractions of the programs in response to changing needs and technologies. Major developments included the establishment of the LDO category in 1948 to retain critical enlisted skills and the revitalization of the CWO program in the 1960s. The roles of LDOs and CWOs continue to be refined to meet the Navy's needs for officer technical specialists.
