Naval Weapon Systems

M60 7.62mm Machine Gun

The M60 machine gun is a gas-operated, belt-fed, air-cooled weapon which fires from an open bolt and in automatic mode only. It was once the primary squad support machine gun of the United States military, being fielded in the squad support and vehicle mounted roles. The vehicle mounts included naval patrol boats, naval vessels, helicopters, wheeled and tracked vehicles.

M240 Medium Machine Gun

The M240 family of medium machine guns has long been employed by all services of the U.S. Armed Forces. It comes in several variants and mounting configurations. These configurations include a coaxial version for armored combat vehicles, a pintle-mounted version for light tactical vehicles and rotary-wing aircraft, and bipod and tripod versions for dismounted infantry units.

M2 .50 Caliber Machine Gun

The Browning M2 .50 caliber machine gun is an automatic, belt-fed, recoil operated, air-cooled, crew-operated machine gun. The system is highly effective against light armored vehicles, low- and slow-flying aircraft, boats and enemy personnel. The M2 is crew transportable with limited amounts of ammunition over short distances. The gun is capable of being modified to fire in single-shot mode, as well as automatic fire. It may be mounted on ground mounts and vehicles as an anti-personnel and anti-aircraft weapon. By repositioning some of the component parts, ammunition may be fed from either the left or right side. A disintegrating metallic link belt is used to feed the ammunition into the weapon.

M134 7.62mm Minigun

The M134 7.62mm minigun was designed to provide a lightweight high rate of fire armament package for use on helicopters and light fixed-wing aircraft. It is an electrically driven, 6 barreled, rotary action weapon. The basic M61 Vulcan has been simplified and redesigned to fire percussion primed 7.62mm ammunition.

Mk19 40mm Machine Gun

The Mk19 Grenade Machine Gun is an air-cooled, disintegrating metallic link-belt fed, blowback operated, fully automatic weapon. It can fire a variety of 40mm grenades. It is crew transportable over short distances with limited amounts of ammunition. The weapon delivers a heavy volume of accurate and continuous firepower against enemy personnel and lightly armored vehicles, as well as hovering rotary-wing aircraft. It is also able to provide indirect fire into an engagement area from a hidden position.

Common Remotely Operated Weapon Station

The Common Remotely Operated Weapon Station (CROWS) is a stabilized mount that contains a sensor suite and fire control software, allowing on-the-move target acquisition and first-burst target engagement. Capable of target engagement under day and night conditions, the CROWS sensor suite includes a daytime video camera, thermal camera, and laser rangefinder. It also features programmable target reference points for multiple locations, programmable sector surveillance scanning, automatic target ballistic lead, automatic target tracking, and programmable no-fire zones.

Mk-38 25mm Machine Gun System

The Mk-38 is a 25mm machine gun installed for ship self-defense to counter High Speed Maneuvering Surface Targets (HSMST). It is a single barrel, air cooled, semi- and full-automatic gun weapon system.

Mk-46 30mm Gun Weapon System

The Mk-46 GWS is a remotely operated naval gun system that uses a 30mm high velocity cannon, a forward looking infrared sensor, a low light television camera, and a laser rangefinder for shipboard self defense against small, high speed surface targets. The Mk-46 GWS includes the Mk-44 Mod.2 30mm cannon, a single barrel, open bolt, dual feed, electrically powered, chain driven automatic cannon. The gun can be operated locally at the gun turret or remotely at the Remote Operating Console in the Combat Information Center (LPD 17 class) or at the Mission Control Center (LCS class).

Mk-75 3-inch Gun

The Mk-75 is a single barrel, lightweight, water-cooled, rapid fire, remote controlled, dual purpose automatic enclosed naval gun. It is suitable for installation on small combatants due to its light weight, and low manpower requirements. One gun mount is installed aboard U.S. Navy frigates and larger U.S. Coast Guard cutters.

Mk-45 5-inch Gun

The Mk-45 (5-inch/54-caliber) lightweight gun is a modern U.S. naval artillery gun mount. It is designed for use against surface warships, anti-aircraft and shore bombardment to support amphibious operations. The gun mount features an automatic loader with a capacity of 20 rounds. These can be fired under full automatic control, taking a little over a minute to exhaust those rounds at maximum fire rate. For sustained use, the gun mount would be occupied by a three-man crew (gun captain, panel operator, and ammunition loader) below deck to keep the gun continuously supplied with ammunition.

Mk-110 57mm Gun

The 57mm Mk-110 Gun Mount is a multi-purpose, medium caliber gun. It delivers high rates of fire with extreme accuracy against surface, airborne and shore-based threats. The primary mission of the Mk-110 Gun Mount is to provide engagement of known surface threats during combat operations in a theater area of operation.

Mk-60 Missile Launcher

The Mk-60 is a surface-to-surface missile system installed for ship self-defense to counter small boat threats. The Mk-60 Griffin Missile System consists of the following system components: MK 4 Battle Management System (BMS), MK 208 Griffin Launcher Module, AN/SSQ-133 BRITE Star II EO/IR, LRF and LD sensor and the BGM-176B Griffin B all-up-round (AUR).

Mk-49 Guided Missile Launching System

The Rolling Airframe Missiles, together with the Mk-49 Guided Missile Launching System (GMLS) and support equipment, comprise the RAM Mk-31 Guided Missile Weapon System (GMWS).

Mk-41 Vertical Launching System

The Mk-41 Vertical Launching System (VLS) is installed aboard United States Navy (USN) surface combatants including Ticonderoga Class Guided Missile Cruisers, Arleigh Burke Class Guided Missile Destroyers and multiple allied Navy platforms. Mk-41 VLS is capable of launching multiple Standard Missile variants, Tomahawk, Vertical Launch Anti-Submarine Rocket (ASROC) and Evolved Sea Sparrow missiles.

Mk-141 Guided Missile Launching System

The Mk-141 is the primary launching system for the Harpoon anti-ship missile aboard U.S. Navy ships. A Mk-141 launcher assembly holds four missiles in canisters at an angle of 35°.

Mk-32 Surface Vessel Torpedo Tube

The Mk-32 Surface Vessel Torpedo Tube is an ASW launching system which pneumatically launches torpedoes over the side of the ship. The SVTT is capable of stowing and launching up to three torpedoes.

Mk-29 Guided Missile Launching System

The Mk-29 Guided Missile Launching System (GMLS) delivers effective protection against airborne and surface threats using the proven RIM-7 NATO Sea Sparrow missile. As the latest upgrade to the Mk-29 GMLS, the Mk-29 MOD 4 allows the launcher to launch the RIM-162 Evolved Sea Sparrow Missile (ESSM).

Mk-15 Phalanx Close-In Weapon System

The Mk-15 Phalanx CIWS provides ships with an inner layer point defense capability against Anti Ship Missiles (ASM), aircraft, and littoral warfare threats that have penetrated other fleet defenses. Phalanx automatically detects, evaluates, tracks, engages, and performs kill assessment against ASM and high speed aircraft threats. Phalanx is the only deployed close-in weapon system capable of autonomously performing its own search, detect, evaluation, track, engage and kill assessment functions. Phalanx also can be integrated into existing ship combat control systems to provide additional sensor and fire-control support to other installed ship weapon systems.

Mk-15 Mod.31 SeaRAM Close-In Weapon System

SeaRAM is an Mk-15 CIWS variant consisting of the combination of two fleet proven weapon systems: the Block 1B Phalanx and the RIM-116 Rolling Airframe Missile (RAM) Guided Missile Weapon System. SeaRAM combines the Phalanx Block 1B search-and-track radar and Electro-Optic sensors, along with its inherent threat evaluation and weapon designation capability, with an 11-round Rolling Airframe Missile launcher assembly on a single mount. The SeaRAM CIWS is a complete combat weapon system that automatically detects, evaluates, tracks, engages, and performs kill assessment against Anti-ship missiles and high speed aircraft threats in an extended self defense battle space envelope around the ship.
