They are also eligible to command the higher echelons of those units, such as destroyer and submarine squadrons, air wings and air groups, and special warfare groups. At the flag officer level, URL officers may also command carrier strike groups, expeditionary strike groups, patrol and reconnaissance groups, task forces, and fleet and force commands. URL officers are also eligible to command shore installations, facilities and activities directly supporting the navy's warfare mission.Mack, VADM William P. and Paulsen, CAPT Thomas D., The Naval Officer's Guide, 9th ed., Naval Institute Press, Annapolis, MD, c1983Mack, VADM William P. and Stavridis, CAPT James, Command at Sea, 5th ed., Naval ...

List Of United States Naval Officer Designators
This is a list of naval officer designators in the United States Navy. In the United States Navy, all active and reserve component officers are assigned to one of four officer communities, based on their education, training, and assignments: Line Officers (divided into Unrestricted Line or URL, Restricted Line or RL, and Restricted Line Special Duty or RL SD), Staff Corps Officers, Limited Duty Officers (LDO), or Warrant Officers (WO/CWO). Each community is further subdivided by primary occupation. Each occupation is identified by a designator. Definition The officer billet designator codes are four-digit numbers used to identify the primary naval specialty qualifications required of the billet incumbent and to administratively categorize officer billets for proper management and identification. They serve as a manpower management tool when used in conjunction with the officer designator codes. These codes are entered in the Manpower Authorizations (OPNAV Form 1000/2) to indica ...

Submarine Warfare
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, Naval mine, mine warfare and Naval mine, mine countermeasures. Submarine warfare consists primarily of Diesel engine, diesel and nuclear submarines using torpedoes, missiles or nuclear weapons, as well as advanced sensing equipment, to attack other submarines, ships, or land targets. Submarines may also be used for reconnaissance and landing of special forces as well as deterrence. In some navies they may be used for task force screening. The effectiveness of submarine warfare partly depends on the anti-submarine warfare carried out in response. American Revolution The first attack by a submarine occurred on September 8, 1776, by the American submarine ''Turtle (submersible), Turtle'' in an unsuccessful attack on the British warship ''Eagle.''

Role LDOs perform tasks similar to those of warrant officers (WO), but the formal definition differences are subtle and focus on the degree of authority and level of responsibility, as well as the breadth of required expertise. The term "limited duty" refers not to an LDO's authority, but rather the LDO's career progression and restrictions. Prior to World War II, a LDO could only advance as far as lieutenant (O-3E) in the Navy and captain (O-3E) in the Marine C ...

Naval Aviator
Naval aviation / Aeronaval is the application of military air power by navies, whether from warships that embark aircraft, or land bases. It often involves '' navalised aircraft'', specifically designed for naval use. Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards, such as in U.S. naval aviators. Naval aviation units are typically projected to a position nearer the target by way of an aircraft carrier. Carrier-based aircraft must be sturdy enough to withstand the demands of carrier operations. They must be able to launch in a short distance and be sturdy and flexible enough to come to a sudden stop on a pitching flight deck; they typically have robust folding mechanisms that allow higher numbers of them to be stored in below-decks hangars and small spaces on flight decks. These aircraft are designed for many purposes, including air-to-air combat, surface attack, submarine attack, search and rescue, matériel tr ...
