SLIRBM - Submarine Launched Intermediate Ballistic MIssile
ATK, in partnership with Lockheed Martin, is developing a submarine-launched, intermediate-range ballistic missile (SLIRBM) — a supersonic, GPS-guided, long-range strike missile capable of flying 1,000 nautical miles in 12 minutes to deliver a 1,000-pound warhead to within 20 meters of its target. The 32-inch-diameter missiles are designed to be launched from Trident ballistic missile firing tubes aboard four U.S Navy Ohio-class submarines that are being converted to guided-missile
submarines. Their mission is to support special operations and deliver long-range conventional strike weapons.
This weapon system will extend the life of the Trident-class ballistic missile submarine to meet changing threat requirements, while making the most of taxpayer investments in the nation's defense system.
The Force Application and Launch from CONUS (FALCON) program, administered by the Defense Advanced Research Projects Agency (DARPA) and the Department of the Air Force, is a three-phased program to develop a capability to deliver substantial payload from within the continental United States (CONUS) to anywhere on Earth (9,000 nautical mile range) in less than two hours.
Under Task 2 of the FALCON program, the government intends to develop and field a Common Air Vehicle (CAV) system to provide a revolutionary ability to execute responsive, effective, and affordable global strike. In addition, the government wishes to conceive a revolutionary Hypersonic Cruise Vehicle (HCV) and significantly advance the design and technology maturity required to field an operational system.
ATK is supporting the Defense Advanced Research Projects Agency (DARPA) and Office of Naval Research (ONR) on the HyFly program, a key DoD effort to develop technology for a time-critical strike missile. Using an innovative flight-test technique, ATK is providing key program risk reduction by carrying out a series of flight experiments employing low-cost, two-stage sounding rockets to transport airframe-integrated, scramjet-powered missile demonstrators to appropriate hypersonic speeds and altitudes.
Initial flight tests of an un-powered airframe at Mach 6 and approximately 60,000 feet have been highly successful. The next series of tests will use a fully operational scramjet engine integrated to the airframe.
Scramfire is the application of scramjet technology to U.S. Army direct-fire and indirect-fire applications and U.S. Navy extended range munitions. A Scramfire application, as envisioned by the U.S. Army, would offer revolutionary advances in lethality, lethality at range, and elimination of depleted uranium as a penetrator material. For the U.S. Navy, Scramfire will facilitate a next generation of extended range munitions for naval surface-fire support with five-inch guns.
For multi-services, Scramfire offers a near-term and affordable development path that supports, ensures, or replaces the capabilities of electro-magnetic guns.
BTERM (Ballistic Trajectory Extended Range Munitions)
BTERM is an innovative extended-range, low-cost, gun-launched projectile capable of operation in the Mk 45 Mod 4 and Mod 2 naval gun systems. ERM will fly more than 60 miles to its target, hitting with lethality inside of 20 meters. Flying a ballistic path to the target, ERM scored direct hits in two flight demonstrations.
MRM - Mid Range Munition
The Mid-Range Munition (MRM) is a cannon-launched, rocket-boosted, precision guided munition that will give the U.S. Army overwhelming lethality, pinpoint accuracy, and significant standoff capability. It is a major lethality component of the U.S Army's Mounted Combat System Block I of the Future Combat System.
The ATK MRM uses a semi-active laser seeker for cooperative targeting and a millimeter wave seeker to autonomously acquire and track the target. Impulse thrusters provide maneuverability to hit targets at extended ranges. This unique control system has no moving parts, providing high reliability at a low cost. The projectile flies to its target on a ballistic trajectory. Before impact, a rocket motor boosts the projectile with its embedded long-rod penetrator to lethal supersonic velocity.
