The Self Defense Test Ship (SDTS) is an asset of the US Navy. It is a refurbished ship that is in some cases operated by remote control; that capability is designed to support self-defense engineering, testing, and evaluation.[ citation needed ]

When uncrewed, it can avoid the safety constraints and other problems associated with crewed ships. During typical operations, launched threats attack the ship, and the combat or weapon system being tested responds to these threats, defending the ship. The pre-arranged attack is, in practice, aimed at a decoy barge pulled 150 feet behind the SDTS in case of damage. Systems installed on the SDTS include MK 57 NATO Sea Sparrow, MK 23 Target Acquisition system, Rolling Airframe Missile, AN/SLQ-32(V) 3 ESM, and Phalanx Close-in Weapon System. [1]

The current SDTS is the former USS Paul F. Foster (DD-964), now known as Ex-Paul F. Foster. In addition to being a remote-controlled ship, she is a test-bed for numerous systems, technologies, and weapons, ranging from bio-fuels to lasers. She replaced the former USS Decatur (DDG-31) in 2003. [2]

The Phalanx CIWS is an automated gun-based close-in weapon system to defend military watercraft automatically against incoming threats such as aircraft, missiles, and small boats. It was designed and manufactured by the General Dynamics Corporation, Pomona Division, later a part of Raytheon. Consisting of a radar-guided 20 mm (0.8 in) Vulcan cannon mounted on a swiveling base, the Phalanx has been used by the United States Navy and the naval forces of 15 other countries. The U.S. Navy deploys it on every class of surface combat ship, except the Zumwalt-class destroyer and San Antonio-class amphibious transport dock. Other users include the British Royal Navy, the Royal Australian Navy, the Royal New Zealand Navy, the Royal Canadian Navy, and the U.S. Coast Guard.

<span class="mw-page-title-main">Anti-ship missile</span> Missile used to attack ships

An anti-ship missile (AShM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea-skimming variety, and many use a combination of inertial guidance and active radar homing. A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way.

<i>Arleigh Burke</i>-class destroyer US Navy guided-missile destroyer class

The Arleigh Burke class of guided-missile destroyers (DDGs) is a United States Navy class of destroyer centered around the Aegis Combat System and the SPY-1D multi-function passive electronically scanned array radar. The class is named for Admiral Arleigh Burke, an American destroyer officer in World War II and later Chief of Naval Operations. With an overall length of 505 to 509.5 feet, displacement ranging from 8,300 to 9,700 tons, and weaponry including over 90 missiles, the Arleigh Burke-class destroyers are larger and more heavily armed than many previous classes of guided-missile cruisers.

The fourth USS Decatur (DD-936) was a Forrest Sherman-class destroyer of the United States Navy in service from 1956 to 1983. She was named for Commodore Stephen Decatur USN (1779–1820). Decatur was modernised as a guided missile destroyer in the mid-1960s and re-designated DDG-31. After her decommissioning in 1983, she operated as the U.S. Navy's Self Defense Test Ship from 1994 to 2003. She was finally sunk as a target the following year.

<i>Spruance</i>-class destroyer Destroyer class of the US Navy

The Spruance-class destroyer was developed by the United States to replace the many World War II–built Allen M. Sumner- and Gearing-class destroyers, and was the primary destroyer built for the United States Navy during the 1970s and 1980s. It was named in honor of U.S. Navy Admiral Raymond A. Spruance, who successfully led major naval battles in the Asiatic-Pacific Theater during World War II such as the Battle of Midway and the Battle of the Philippine Sea.

Foster USN (1889–1972), is a Spruance-class destroyer built by the Ingalls Shipbuilding Division of Litton Industries at Pascagoula, Mississippi. She was commissioned on 21 February 1976 and decommissioned on 27 March 2003. She is now ex-Paul F. Foster, serving as a Self Defense Test Ship for experimental U.S. Navy weapons and sensors. She is the last Spruance-class destroyer still afloat.

The RIM-7 Sea Sparrow is a U.S. ship-borne short-range anti-aircraft and anti-missile weapon system, primarily intended for defense against anti-ship missiles. The system was developed in the early 1960s from the AIM-7 Sparrow air-to-air missile as a lightweight "point-defense" weapon that could be retrofitted to existing ships as quickly as possible, often in place of existing gun-based anti-aircraft weapons. In this incarnation, it was a very simple system guided by a manually aimed radar illuminator.

USS <i>Fletcher</i> (DD-992) Spruance-class destroyer

USS Fletcher (DD-992), the thirtieth Spruance-class destroyer, was part of the first major class of United States Navy surface ships to be powered by gas turbines. She was commissioned in July 1980 and was deployed mainly in the western and southern Pacific, but also voyaged to the Indian Ocean and Persian Gulf. She was the second ship in the U.S. Navy to bear this name but the first to be named after Admiral Frank Jack Fletcher. After her decommissioning in 2004, she was sunk in a torpedo test exercise in 2008.

<span class="mw-page-title-main">RIM-116 Rolling Airframe Missile</span> Small, lightweight, infrared homing surface-to-air missile

The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the German, Japanese, Greek, Turkish, South Korean, Saudi Arabian, Egyptian, Mexican, UAE, and United States navies. It was originally intended and used primarily as a point-defense weapon against anti-ship missiles. As its name indicates, RAM rolls as it flies. The missile must roll during flight because the RF tracking system uses a two-antenna interferometer that can measure phase interference of the electromagnetic wave in one plane only. The rolling interferometer permits the antennas to look at all planes of incoming energy. In addition, because the missile rolls, only one pair of steering canards is required. As of 2005, it is the only U.S. Navy missile to operate in this manner.

The RIM-66 Standard MR (SM-1MR/SM-2MR) is a medium-range surface-to-air missile (SAM), with a secondary role as an anti-ship missile, developed for the United States Navy (USN). A member of the Standard Missile family of weapons, the SM-1 was developed as a replacement for the RIM-2 Terrier and RIM-24 Tartar that were deployed in the 1950s on a variety of USN ships. The RIM-67 Standard (SM-1ER/SM-2ER) is an extended range version of this missile with a solid rocket booster stage.

<span class="mw-page-title-main">RIM-67 Standard</span> Extended range surface-to-air missile with anti-ship capability

The RIM-67 Standard ER (SM-1ER/SM-2ER) is an extended range surface-to-air missile (SAM) with a secondary anti-ship capability, originally developed for the United States Navy (USN). The RIM-67 was developed as a replacement for the RIM-8 Talos, a 1950s system deployed on a variety of USN ships, and eventually replaced the RIM-2 Terrier as well, since it was of a similar size and fitted existing Terrier launchers and magazines. The RIM-66 Standard MR was essentially the same missile without the booster stage, designed to replace the RIM-24 Tartar. The RIM-66/67 series thus became the US Navy's universal SAM system, hence the designation "Standard Missile".
