Fleet in beingIn naval warfare, a "fleet in being" is a naval force that extends a controlling influence without ever leaving port. Were the fleet to leave port and face the enemy, it might lose in battle and no longer influence the enemy's actions, but while it remains safely in port, the enemy is forced to continually deploy forces to guard against it. A "fleet in being" can be part of a sea denial doctrine, but not one of sea control. The term was first used in 1690 when Lord Torrington, commander of the Royal Navy forces in the English Channel, found himself facing a stronger French fleet.
Aegis Combat SystemThe Aegis Combat System is an American integrated naval weapons system, which uses computers and radars to track and guide weapons to destroy enemy targets. It was developed by the Missile and Surface Radar Division of RCA, and it is now produced by Lockheed Martin. Initially used by the United States Navy, Aegis is now used also by the Japan Maritime Self-Defense Force, Spanish Navy, Royal Norwegian Navy, Republic of Korea Navy, and Royal Australian Navy, and is planned for use by the Royal Canadian Navy.
Bomb vesselA bomb vessel, bomb ship, bomb ketch, or simply bomb was a type of wooden sailing naval ship. Its primary armament was not cannons (long guns or carronades) – although bomb vessels carried a few cannons for self-defence – but mortars mounted forward near the bow and elevated to a high angle, and projecting their fire in a ballistic arc. Explosive shells (also called bombs at the time) or carcasses were employed rather than solid shot. Bomb vessels were specialized ships designed for bombarding (hence the name) fixed positions on land.
