Wolf pack

For other uses, see Wolfpack (disambiguation).

The term wolf pack refers to the mass-attack tactics against convoys used by German U-boats of the Kriegsmarine during the Battle of the Atlantic and submarines of the United States Navy against Japanese shipping in the Pacific Ocean in World War II.

Karl Dönitz used the term Rudel to describe his strategy of submarine warfare—Rudel translates best as "pack" of animals and has become known in English as "wolf pack" (Wolfsrudel), a more accurate metaphoric, but not literal, translation.

American wolf packs, officially called coordinated attack groups, usually comprised three boats that patrolled in close company and organized before they left port under the command of the senior captain of the three. "Swede" Momsen devised the tactics and led the first American wolf pack from Midway on 1 October, 1943 - Cero (SS-225), Shad (SS-235), and Grayback (SS-208).

Although the wolf packs proved a serious threat to Allied shipping, the Allies developed countermeasures to turn the U-boat organization against itself. Most notably was the fact that wolf packs required extensive radio communication to coordinate the attacks. This left the U-boats vulnerable to a device called the High Frequency Direction Finder (HF/DF or "Huff-Duff") which allowed Allied naval forces to determine the location of the enemy boats transmitting and attack them. Also, effective air cover, both long-range planes with radar, and escort carriers and blimps, allowed U-boats to be spotted as they shadowed a convoy (waiting for the cover of night to attack). The destroyers of the Atlantic also used depth charges and other small mines which could be dropped off the ships' side.

Wolf packs fell out of use during the Cold War: modern submarines have far better weapons and underwater speed than those of World War II, so there is no need for them to operate in large groups. Instead, the United States Navy deploys its attack submarines on individual patrols, with the exception of one or (rarely) two attack submarines in each carrier group. American ballistic missile submarines have always operated alone. (Soviet ballistic missile submarines operate in well-protected bastions.) However, with the opening shots of the Iraq War in March, 2003, the term "wolf pack" was brought back into use to describe the fleet of American and British nuclear submarines which operated together in the Red Sea, firing Tomahawk missiles at Iraqi targets. USS Providence was the first boat to fire its entire load of missiles and earn the nickname "Big Dog of the Red Sea Wolf Pack."

Recently the phrase "wolf pack" has been applied to possible Iranian missile boat tactics in the event of an hypothetical clash with the U.S. Navy; a massive attack of small boats armed with missiles and torpedoes on a single (or a few) ships in order to overrun or saturate the Aegis defence system; such attacks allow the possibility of effective suicide boat deployment.
