Alliant Techsystems (ATK, Minneapolis, Minn.) has received an $18 million contract to upgrade the solid propellant rocket motor of Raytheon's (Waltham, Mass.) Block 2 Rolling Airframe Missile (RAM). Under terms of the contract, ATK will design, develop and test a boost/sustain rocket motor that extends the missile's range and provides the basis for improved maneuverability, ultimately affording the weapon system significant new performance capabilities. The new rocket motor's graphite fiber composite case will minimize overall missile weight and allow it to withstand the high G-force maneuvers required to defeat advanced anti-ship cruise missiles and other evolving threats. ATK will increase the diameter of the RAM motor from the current 5-inch design to 6.25 inches, allowing the missile to carry additional propellant required for extended range. ATK also has signed a letter of agreement with Lockheed Martin (Bethesda, Md.) to produce fiber-placed components for low-rate initial production (LRIP) on the F-35 Lightning II, also known as the Joint Strike Fighter. Under the terms of the agreement, ATK will use advanced fiber-placement technology to provide upper wing-box skins, lower wing-box skins, and nacelle skins during LRIP lots one through three for the conventional takeoff and landing and short-takeoff/vertical-landing variants of the F-35. ATK also will provide upper wing-box and nacelle skins for the F-35 carrier variant. Beginning with LRIP lot four, ATK is under contract to supply a minimum of 30 percent of the total fiber-placed composite components used in wing production.
