Through Battle, Sea and Strategy

Naval tactics are distinct from naval strategy. Naval tactics are concerned with the movements a commander makes in battle, typically in the presence of the enemy. Naval strategy concerns the overall strategy for achieving victory and the large movements by which a commandant or commander secures the advantage of fighting at a place convenient to himself.

Modern naval tactics are based on tactical doctrines developed after World War II, following the obsolescence of the battleship and the development of long-range missiles. Since there has been no major naval conflict since World War II, apart from the Indo-Pakistani Naval War of 1971 and the Falklands War, many of these doctrines reflect scenarios developed for planning purposes. Critics argue that the collapse of the Soviet Union and the subsequent reduction in the size and capabilities of the Russian Navy renders most such fleet-on-fleet scenarios obsolete.

Key concepts

A central concept in Western modern naval fleet warfare is battlespace: a zone around a naval force within which a commander is confident of detecting, tracking, engaging and destroying threats before they pose a danger. As in all forms of warfare, a critical objective is to detect the enemy while avoiding detection.

The open sea provides the most favorable battlespace for a surface fleet. The presence of land and the topography of an area compress the battlespace, limit the opportunities to maneuver, make it easier for an enemy to predict the location of the fleet, and make the detection of enemy forces more difficult. In shallow waters, the detection of submarines and mines is especially problematic.

One scenario that was the focus of American and NATO naval planning during the Cold War was a conflict between two modern and well equipped fleets on the high seas, the clash of the United States/NATO and the Soviet Union/Warsaw Pact. Because the Cold War ended without direct total war between the two sides, the outcome of such an action remains hypothetical, but was broadly understood to include, towards the late Cold War, multiple salvoes of anti-ship missiles against the Americans and U.S. attempts to air strike Soviet land bases and/or fleets. Given the eventual strategic surprise effectiveness of anti-ship missiles, the outcome of such a clash is far from being clear.

The main consideration is for carrier battle group (CVBGs). Critics of current naval doctrine argue that although such a fleet battle is unlikely to occur in the foreseeable future, Cold War thinking continues to dominate naval practice. However, others point toward the increased naval budgets of Russia and South and East Asia as a possibility that conventional naval combat in the future may become relevant again.

Naval tactics and weapons systems can be categorized by the type of opponents they are intended to fight. Anti-air warfare (AAW) involves action against aircraft and incoming missiles. Anti-surface warfare (ASuW) focuses on attacking and defending against surface warships. Anti-submarine warfare (ASW) deals with the detection and destruction of enemy submarines.

The key threat in modern naval combat is the airborne cruise missile, which can be delivered from surface, subsurface or airborne platforms. With missile speeds ranging up to Mach 4, engagement time may be only seconds and such missiles can be designed to "skim the sea" mere meters above the sea surface. The key to successful defence was argued to be to destroy the launch platform before it fires, thus removing a number of missile threats at once. This is not always possible so the anti-aircraft warfare (AAW) resources need to be balanced between the outer and inner air battles. Missile tactics are now mostly fire and forget in the manner of the Harpoon or Exocet or utilize over-the-horizon targeting, such as the Tomahawk or Silkworm. Close-range missile defence in the modern age depends heavily on close-in weapon systems (CIWS) such as the Phalanx or Goalkeeper.

Most naval vessels can only withstand one or two missile strikes before they are put out of commission. In the 1970s, defense planners began developing backup defenses like the Sea Sparrow missile and CIWS. Large navies like the US Navy responded to the advent of missiles by adopting a “haystack” distribution with ships that are more dispersed to protect major targets like aircraft carriers. The 1985 article “Cruise Missile Warfare” in US Naval Institute's Proceedings used a relationship proposed by the Brookings Institution to assess the likeliness a ship would be put out of commission by missile damage. The number of hits needed to put a ship out of action is related to the length of the ship. A hit by a modern warhead would incapacitate a modern 300-foot long warship. Another similar sized warhead is needed for each additional 100 feet.

Though traveling under water and at lower speeds, torpedoes present a similar threat. As is the case with missiles, torpedoes are self-propelled and can be launched from surface, subsurface, and air platforms. Modern versions of this weapon present a wide selection of homing technologies specially suited to their particular target. There are far fewer means of destroying incoming torpedoes compared to missiles.

Submarines, as subsurface launching platforms, present an important threat to conventional naval operations. Anechoic coatings and ultra-quiet pump-jets provide modern submarines with the advantage of stealth. The move towards shallow water operations has greatly increased this advantage. Mere suspicion of a submarine threat can force a fleet to commit resources to removing it, as the consequences of an undetected enemy submarine can obviously be lethal. The threat posed by British submarines during the Falklands War of 1982 was one of the reasons why the Argentine Navy was limited in its operations. A single submarine at sea also impacted operations in the Indo-Pakistani Naval War of 1971.

Conventional naval forces are also seen as providing a capability for power projection. In several naval operations, the aircraft carrier has been used to support land forces rather than to supply air control over the sea. Carriers were used in this way during the Gulf War.
