The development of the VLS ASROC underwent many delays, and it was not deployed on any ships until 1993.

However, the torpedo's inherent limitations in speed of attack and detection by the target have led to the development of missile-borne anti-submarine weapons that can be delivered practically on top of the enemy submarine, such as ASROC.

An ASROC missile could hypothetically carry a 10 kiloton W44 nuclear warhead, although the W44-armed nuclear weapons were retired by 1989, and all types of nuclear depth bombs were removed from deployment.

Most other US Navy and allied navy destroyers, destroyer escorts, frigates, and several different classes of cruisers only carried the one ASROC ' matchbox ' MK 112 launcher with eight ASROC missiles ( although later in service, some of those missiles could be replaced by the Harpoon anti-ship missile ).

They are also used in conjunction with other weapons ; for example the Mark 46 torpedo used by the United States becomes the warhead section of the ASROC ( Anti-Submarine ROCket ) and the CAPTOR mine ( CAPsulated TORpedo ) is a submerged sensor platform which releases a torpedo when a hostile contact is detected.

His role in The Bedford Incident was that of a young ensign who becomes so rattled by the needling of his Captain ( Richard Widmark ) that he accidentally fires an ASROC at a Soviet submarine, thus ( we are given to understand ) starting World War III.

Hedgehog remained in service with the United States Navy into the cold war until both Hedgehog and the less satisfactory Weapon Alpha were replaced by ASROC.

The RUM-139 VL-ASROC is an anti-submarine missile in the ASROC family, currently built by the Lockheed Martin company for the U. S. Navy.

The resulting XFC-130H aircraft were modified by the installation of 30 rockets in multiple sets: eight forward-pointed ASROC rocket motors mounted around the forward fuselage to stop the aircraft, eight downward-pointed Shrike rockets fuselage-mounted above the wheel wells to brake its descent, eight rearward-pointed MK-56 rockets ( from the RIM-66 Standard Missile ) mounted on the lower rear fuselage for takeoff assist, two Shrikes mounted in pairs on wing pylons to correct yaw during takeoff transition, and two ASROCs mounted at the rear of the tail to prevent it from striking the ground from over-rotation.

Two of the tests were of operational weapons systems — the ASROC anti-submarine rocket and the Polaris SLBM ( the latter test, Frigate Bird, was the only operational submarine-launched ballistic missile test with a live warhead ever undertaken by the USA ).

Ikara's range at was double that of ASROC.

Only the rocket-thrown weapons ( ASROC and Ikara ) are available for use in all-weather conditions and at instant readiness.

The reverse-mounted ( forward-facing ) eight ASROC rockets for decelerating the aircraft's forward speed were situated in pairs on the upper curvature of the fuselage behind the cockpit, and at the midpoint of each side of the fuselage beneath the uppers.

The ASROC has been deployed on scores of warships of many other navies, including Canada, Germany, Italy, Japan, the Republic of China, Greece, Pakistan and others.

The Mk 54 can be fired from surface ships via the Mark 32 surface vessel torpedo tubes or the vertical launch anti-submarine rocket ( ASROC ) systems, and also from most ASW aircraft.

Ships with the Mk 26 GMLS, and late marks of the Mk 10 GMLS aboard the " Belknap "- class, could accommodate ASROC in these power-loaded launchers ( the Mk 13 GMLS was not able to fire the weapon, as the launcher rail was too short ).

In order to provide the ships with a credible anti-submarine weapon, the FRAM upgrade centered on the addition of AN / SQS-23 SONAR and two new weapon systems, the ASROC rocket-assisted torpedo launcher with a range of 1 – 5 miles, and the DASH antisubmarine helicopter with a range of up to.

The main developments were the new Mark 25 trainable launcher developed from the ASROC launcher, and the Mark 115 manually aimed radar illuminator that looked like two large searchlights.

Larger-scale devices which serve to launch rockets include the multiple rocket launcher, a type of unguided rocket artillery system ; the transporter erector launcher, a vehicle with an integrated prime mover that can carry, elevate to firing position and launch one or more missiles and various launchers for guided missiles, including ones for surface-to-air missiles, anti-ship missiles, and antisubmarine warfare guided missiles ( see ASROC, Sea Lance, etc.

This system was phased out in the 1990s and replaced with the RUM-139 Vertical Launch ASROC, or " VLA ".

The 31 U. S. Navy Spruance-class destroyers were all built with the Mark 16 Mod 7 ASROC Launching Group and MK 4 ASROC Weapons Handling System ( AWHS ) reload system.

Agerholm launched an ASROC anti-submarine rocket armed with a nuclear depth bomb during the Operation Dominic I and II | Swordfish test of 1962

The first VLS ASROC missile was an RUR-5 ASROC with an upgraded solid-fuel booster section and a digital guidance system.

The attacking ship would then fire an ASROC missile carrying an acoustic homing torpedo or a Nuclear Depth Bomb ( NDB ) onto an unguided ballistic trajectory toward the target.

ASROC ( for Anti-Submarine ROCket ) is an all-weather, all sea-conditions anti-submarine missile system.

However, before RAT-C reached initial operational status in 1960 aboard the large US Navy destroyer-leader Norfolk, its name was changed to the present ASROC.

In cases where the ASROC missile carried an NDB, the unguided bomb would sink quickly to a predetermined depth where it would detonate.

The nuclear-armed ASROC was never used beyond one or two tests in 1961-62.

The first ASROC system using the MK-112 " Matchbox " launcher, was developed in the 1950s and installed in the 1960s.

Thus, each Spruance-class destroyer originally carried a maximum total of 24 ASROC.
