Anti-Surface Warfare

From Wikipedia, the free encyclopedia

Anti-surface warfare, or ASUW (sometimes ASuW or less commonly, anti-surface unit warfare) is a type of naval warfare directed against surface ships. More generally, it is any weapons, sensors, or operations intended to attack or limit the effectiveness of an adversary's surface ships.

Broadly speaking, ASUW can be divided into four categories:

  • Air (or aviation) — Anti-surface warfare conducted by aircraft. Historically, this was conducting primarily through bombing and strafing runs (and in some cases by suicide (Kamikaze attack). Today, air ASUW is generally conducted by stand-off attacks using air-launched cruise missiles (ALCM) or air-to-surface missiles (ASM).
  • Submarine — Anti-surface warfare conducted by submarines. historically, this was conducted using deck guns and torpedoes. More recently, the submarine-launched cruise missile (SLCM) (or, more commonly, Anti-Ship Cruise Missile (ASCM)) has become a preferred weapon.
  • Shore — Historically, this refers to shore bombardment from artillery and canons. Today, coastal-launched cruise missiles are also considered.

Some weapons used in ASUW include:
