Fleet in Being - Concept

Concept

The 'fleet in being' concept is based on the assumption that the fleet is relatively safe in port, even if near the enemy. After the battle of Taranto and the attack on Pearl Harbor, however, it became obvious that air power made a fleet concentrated in a port vulnerable, and a fleet in being was normally no longer a safe option. It is, of course, possible to imagine a situation where a fleet is still relatively safe in harbour, such as the opponent being unwilling to attack them in harbour for political reasons. After looking at the alternatives; "The strategy that was accepted for the Argentine Navy was one of a 'fleet in being' concept ... The fleet would not conduct a direct attack; they would only attack when the odds were in their favor. Otherwise they would remain outside any declared British exclusion zones and wait for a target of opportunity".

The idea of a 'fleet in being' can be generalised to forces other than naval. A fortress under siege is essentially an 'army in being,' which ties up enemy forces without leaving the fortress or doing much fighting. During the Gulf War, Saddam Hussein used his air force with an operational doctrine analogous to 'fleet in being.' The mere presence of the Iraqi Air Force in hardened bunkers forced the coalition attacking Iraq to act cautiously and to escort its bomber sorties until the aircraft shelters were found to be vulnerable.
