Assistant Secretary of the Navy (ASN) is the title given to certain civilian senior officials in theUnited States Department of the Navy.

From 1861 to 1954, the assistant secretary of the Navy was the second-highest civilian office in the Department of the Navy (reporting to theUnited States secretary of the Navy). That role has since been supplanted by the office ofUnder Secretary of the Navy and the office of Assistant Secretary of the Navy has been abolished. There have, however, been a number of offices bearing the phrase "Assistant Secretary of the Navy" in their title (see below for details).

At present, there are four Assistant secretaries of the Navy, each of whom reports to and assists the secretary of the Navy and the under secretary of the Navy:

• Assistant Secretary of the Navy (Research, Development and Acquisition)
• Assistant Secretary of the Navy (Manpower and Reserve Affairs)
• Assistant Secretary of the Navy (Financial Management and Comptroller)
• Assistant Secretary of the Navy (Energy, Installations and Environment)
• TheGeneral Counsel of the Navy is equivalent in rank to the four Assistant Secretaries.

The Office of the Assistant Secretary of the Navy was established in 1861, to provide a senior deputy to the Secretary. The Assistant Secretary was responsible for the Navy's civilian personnel, as well as for administration ofshore facilities (such as naval bases and shipyards).Gustavus Fox was the first to hold the post, serving throughout the Civil War. The office was disestablished in 1869, during Reconstruction, but was reestablished by Congress on July 11, 1890.James R. Soley was the first to be appointed to the newly reestablished position.

The Assistant Secretary was the Navy's number-two civilian until 1940, when Congress established the position of Under Secretary of the Navy, who was given oversight of the Assistant Secretary's activities.James V. Forrestal, laterSecretary of Defense, was the first to serve as Under Secretary; he held the post until 1944, when he becameSecretary of the Navy.

During the 20th century, the responsibilities of the Assistant Secretary were divided among several officials. During the 1920s, for example, to reflect the increasing importance ofnaval aviation, Congress established the position ofAssistant Secretary of the Navy for Air.

The office of Assistant Secretary of the Navy was disestablished in 1954.^[1]

• U.S. PresidentTheodore Roosevelt served as Assistant Secretary of the Navy from 1897 to 1898, during the William McKinley administration.

It is notable for his taking the initiative to order AdmiralGeorge Dewey to sail toManila where he sank theSpanish Pacific Fleet at the very outset of the war.
