Vice admiral (United States) in the context of "United States Maritime Service"

In the United States Armed Forces, a lieutenant general is a three-star general officer in the United States Army, Marine Corps, Air Force, and Space Force.

A lieutenant general ranks above a major general and below a general. It is abbreviated as LTG in the Army, LtGen in the Marine Corps, and Lt Gen in the Air Force and Space Force and is equivalent to the rank of vice admiral in the United States uniformed services that use naval ranks. The pay grade of lieutenant general is O-9.

Admiral (abbreviated as ADM) is a four-star commissioned officer rank in the United States Navy, the United States Coast Guard, and the United States Public Health Service Commissioned Corps with the pay grade of O-10. Admiral ranks above vice admiral and below fleet admiral in the Navy; the Coast Guard and the Public Health Service do not have an established grade above admiral. Admiral is equivalent to the rank of general in the other uniformed services. The National Oceanic and Atmospheric Administration Commissioned Officer Corps (NOAA Corps) has never had an officer hold the grade of admiral. However, 37 U.S.C. § 201 of the U.S. Code established the grade for the NOAA Corps, in case a position is created that merits the four-star grade.

Since the five-star grade of fleet admiral has not been used since 1946, the grade of admiral is the highest appointment an officer can achieve in the United States Navy, the United States Coast Guard, and the United States Public Health Service Commissioned Corps.

The Environmental Science Services Administration (ESSA) was a United States Federal executive agency created in 1965 as part of a reorganization of the United States Department of Commerce. Its mission was to unify and oversee the meteorological, climatological, hydrographic, and geodetic operations of the United States. It operated until 1970, when it was replaced by the new National Oceanic and Atmospheric Administration (NOAA).

The first U.S. Government organization with the word "environment" in its title, ESSA was the first such organization chartered to study the global natural environment as whole, bringing together the study of the oceans with that of both the lower atmosphere and the ionosphere. This allowed the U.S. Government for the first time to take a comprehensive approach to studying the oceans and the atmosphere, also bringing together various technologies – ships, aircraft, satellites, radar, and communications systems – that could operate together in gathering data for scientific study.

The commandant of the Coast Guard is the service chief and highest-ranking member of the United States Coast Guard. The commandant is an admiral, appointed for a four-year term by the president of the United States upon confirmation by the United States Senate. The commandant is assisted by a vice commandant, who is also an admiral, and two area commanders (U.S. Coast Guard Pacific Area and U.S. Coast Guard Atlantic Area) and two deputy commandants (deputy commandant for operations and deputy commandant for mission support), all of whom are vice admirals.

Though the United States Coast Guard is one of the six military branches of the United States, unlike the other service chiefs, the commandant of the Coast Guard is not a member of the Joint Chiefs of Staff. The commandant is, however, entitled to the same supplemental pay as each member of the Joint Chiefs, per 37 U.S.C. § 414(a)(5) ($4,000 per annum in 2009), and is accorded privilege of the floor under Senate Rule XXIII(1) as a de facto Joint Chiefs of Staff member during presidential addresses.

James Bond Stockdale (December 23, 1923 – July 5, 2005) was a U.S. Navy vice admiral, aviator, and Stoic philosopher who received the Medal of Honor in 1976 for his leadership as a POW for over seven years during the Vietnam War.

Stockdale was the most senior naval officer held captive in Hanoi, North Vietnam. He led aerial attacks from the carrier USS Ticonderoga (CVA-14) during the 1964 Gulf of Tonkin incident. On his next deployment, while commander of Carrier Air Wing Sixteen aboard the carrier USS Oriskany (CV-34), his A-4 Skyhawk jet was shot down in North Vietnam on September 9, 1965. He served as president of the Naval War College from October 1977 until he retired from the navy in 1979. As vice admiral, James Bond Stockdale was the president of The Citadel from 1979 to 1980.
