Description: All U.S. attack and ballistic missile submarines (SSN and SSBNs) carry the Mk 48 torpedo. The improved Mk 48 ADCAP is carried by the Seawolf (SSN-21)-class, Los Angeles (SSN-688)-class, and Ohio (SSBN-726)-class submarines; it will also arm the Virginia (SSN-774)-class attack submarines. The Mk 48 ADCAP's upgraded guidance and propulsion systems enable U.S. submarines to attack hostile surface ships or submarines in the presence of torpedo countermeasures and in adverse environmental conditions, including shallow water. A modification to the ADCAP (ADCAP MOD) increases guidance and control speed and memory, and significantly reduces radiated noise. Both torpedoes combat fast, deep-diving nuclear submarines and high-performance surface ships. The ADCAP is also effective against the diesel submarine (SSK) threat in the littoral environment, and the ADCAP MOD will improve the torpedo's performance against all threats in all operational environments. Both variants can operate with or without wire guidance using active and/or passive homing, and can execute preprogrammed search and attack procedures. A follow-on hardware upgrade, known as Common Broadband Advanced Sonar System (CBASS), began development in FY 1998. CBASS will further enhance the torpedo's performance against modern SSNs and SSKs employing advanced countermeasures.
Program Status: ADCAP MODs upgrade production began in FY 1995. An additional 50 torpedoes are to be upgraded in FY 2001, with the remaining 375 weapons to be upgraded between FY 2002 and 2005. CBASS MODs are scheduled for implementation on 462 torpedoes between FY 2004 and 2007.
Developer/Manufacturer: ADCAP MOD: Raytheon, Fullerton, California. CBASS: To be determined.
Description: The Trident II/D5 is the sixth generation of the U.S. Navy's Fleet Ballistic Missile (FBM) program, which started in 1955. The D5 is a three-stage, solid-propellant, inertial-guided submarine-launched ballistic missile (SLBM) with a range greater than 4,000 nautical miles and accuracy measured in hundreds of feet. Each of the first eight Ohio (SSBN-726)-class submarines carry 24 Trident I/C4 missiles and are stationed in Bangor, Washington; the other ten ships, stationed in Kings Bay, Georgia, carry Trident II/D5 missiles. Conversion of four of the C4 ships to carry the Trident II/D5 missile began in Fiscal Year 2000 and will be completed in Fiscal Year 2008. Trident II missiles are capable of carrying W76 or W88 Multiple Independently Targeted Reentry Vehicles (MIRVs). In operation, these missiles have been declared at eight MIRV warheads under the Strategic Arms Reduction Treaty (START). The Navy continues to address future deterrence requirements against weapons of mass destruction and disruption, and the Trident II/D5 will ensure that the United States has a modern, survivable strategic deterrent.
Program Status: Production of 53 D5 missiles remains to reach the inventory objective of 425 missiles for 14 Trident II/D5 SSBNs in two oceans. Planned procurement through FY 2005 is 5-to-12 missiles per year.
Description: The Navy Aerial Target Program provides threat representative and threat replicative targets to test and train against realistic threats-high-altitude supersonic diving missiles; aircraft; subsonic sea-skimming anti-ship cruise missiles; supersonic sea-skimming cruise missiles; and ballistic missiles. The Navy Aerial Target Program assesses foreign threats, develops new targets to replicate the threats, and procures the targets for Fleet training and Test and Evaluation. New efforts within the program include the development and procurement of two new target types. First, a next-generation Super Sea-Skimming Target (SSST) to meet the emergence of supersonic anti-ship cruise missile proliferation. Second, a ballistic missile target concept is being explored to ensure that adequate training and tracking assets will be available to support Area and Theater-wide Ballistic Missile Defense (TBMD) testing, evaluation, and training.
Program Status: The SSST developmental contract was awarded in June 2000 to Orbital Sciences, with first delivery expected in Fiscal Year 2003. A timeline to field ballistic missile targets to meet the requirements of the Navy Area TBMD program is under development.
Developer/Manufacturer: There are multiple targets and developers/manufacturers under the Aerial Targets Program.
AGS Advanced Gun System
Description: AGS is a 155mm Gun Weapon System planned for installation in the DDX future surface warships (see separate program summary) to provide high-volume, sustainable fires in support of amphibious operations and the joint land battle. AGS is a fully integrated gun weapon system that will include at least two separate gun systems for each DDX warship. Each gun system will be capable of independently firing up to 12 rounds per minute from an automated magazine storing as many as 750 rounds. The AGS program also includes development of a 155mm long-range guided munition, which leverages Extended-Range Guided Munition development (see ERGM program summary). The 155mm Long-Range Land Attack Projectile (LRLAP) will be the first of a family of AGS munitions. AGS is being designed to meet the reduced manning and low radar-signature
requirements of DDX.
Program Status: The program started in FY 1999. The first gun system is scheduled for delivery in FY 2007, to support the first DDX IOC. The AGS and its associated family of munitions are being developed using Cost As an Independent Variable (CAIV) principles.
Developer/Manufacturer: United Defense Limited Partnership, Minneapolis, Minnesota, in partnership with the two DDX industry teams.
ALAM Advanced Land-Attack Missile
Description: ALAM will provide VLS-equipped surface warships and potentially land-attack/guided-missile submarines with a surface/subsurface fire-support weapon possessing the range, lethality, responsiveness, and accuracy against a broader target set than is possible today. This capability is needed to fully meet the Marine Corps' fire-support requirements for Expeditionary Maneuver Warfare, including Operational Maneuver from the Sea and Ship-to-Objective-Maneuver Operational Concepts. ALAM addresses key naval fires operational and tactical targets, including armored, mobile/moving, and-hardened and bunkers, with greatly enhanced lethality. ALAM is slated to be the future land-attack missile in the land-attack family of munitions.
Program Status: An 18-month AoA completed May 2001. Boost Glide and Super Sonic Cruise missile constructs presented well. Additional detailed design studies are under consideration to further define the ALAM concept. Depending upon available funding, ALAM introduction and IOC will be coincidental with DDX IOC.
Developer/Manufacturer: To be determined.
AMNS Airborne Mine Neutralization System
Description: The Airborne Mine Neutralization System (AMNS) is an expendable, remotely operated mine neutralization device, leveraging NDI and COTS technologies, deployed from MH-60S helicopters, that will be capable of providing identification and neutralization of proud (unburied), close-tethered, and in-volume naval mines. The MH-60S will deploy a remotely operated AMNS neutralization device to a previously detected mine location where it will reacquire and neutralize identified targets.
The AMNS will be fully integrated into the MH-60S avionics architecture.
Program Status: A competitive contract was awarded December 1998 for the integration and testing of a COTS/NDI AMNS system from a MH-53E helicopter. Beginning in FY 2001, AMNS systems are being procured for the MH-53E to provide a near-term fleet interim MCM capability. Follow-on AMNS system integration onto the MH-60S began in Fiscal Year 2001 and will continue through Fiscal Year 2003 Milestone III decision. AMNS IOC on the MH-60S is projected for Fiscal Year 2005.
Developer/Manufacturer: Lockheed Martin, Syracuse, New York; and STN Atlas, Germany.
ABS Assault Breaching Programs
Description: The Assault Breaching Programs encompass several projects to counter the threats to naval forces from current and projected future land and naval mines and obstacles in shallow water, very shallow water, and surf zone approaches to amphibious operating areas.
Program Status: Research and development are continuing.
Developer/Manufacturer: Multiple sources to be determined.
