    "excerpt": "By Lukasz Prus (Defence Industry Europe) Image: Northrop Grumman. Northrop Grumman is expanding missile production at its Allegany Ballistics Laboratory in West Virginia, adding capacity for 300 strike missiles a year. The investment forms part of a broader $2 billion effort to increase munitions output and modernise U.S. defence manufacturing. The Naval Industrial Reserve Ordnance Plant at ABL operates in partnership with the U.S. Navy. The complex produces many of the tactical solid rocket motors used across U.S. missile programmes. These motors provide propulsion for weapons requiring precision, range and lethality. ABL’s production role has grown from its origins during the Second World War to support current U.S. military requirements. Northrop Grumman has invested millions of dollars in expanding and modernising the site since 2018. That work includes Plant 4, a 113,000-square-foot modular missile integration facility built to increase production speed and scale. The facility uses automation and data-driven process controls across its manufacturing operations. Northrop Grumman said it would increase capacity by 300 strike missiles annually while reducing lead times and strengthening quality assurance. The company’s wider $2 billion munitions investment also targets the production of 155mm artillery ammunition. One project is developing new manufacturing methods for...",
