Washington, DC, August 27 - Northrop Grumman, a leading aerospace manufacturer, has achieved a remarkable milestone in the production of the F-35 Lightning II, a fifth-generation stealth multirole fighter critical to U.S. and allied air forces. The company announced it can now deliver a center fuselage for the F-35 every 30 hours at its Palmdale, California, facility, marking a significant leap in defense manufacturing efficiency. This accelerated production pace, reported on August 22, 2025, underscores Northrop Grumman’s ability to combine speed, precision, and reliability, ensuring the U.S. and its international partners maintain a robust fleet of advanced fighters. The F-35, developed by Lockheed Martin with key contributions from Northrop Grumman, BAE Systems, and Pratt & Whitney, is designed for air superiority, ground attack, reconnaissance, and electronic warfare. Its three variants, F-35A for conventional takeoff and landing, F-35B for short takeoff and vertical landing, and F-35C for carrier operations, provide unmatched versatility across diverse mission profiles. This milestone enhances the readiness of U.S. forces and strengthens global air capabilities by ensuring a steady supply of this critical airframe component.

The center fuselage, a core structural element of the F-35, is vital to the aircraft’s performance, housing fuel tanks, internal weapons bays, air intakes, and flight-operable mechanisms. Its precise assembly is essential for maintaining the aircraft’s stealth capabilities and mission effectiveness. Northrop Grumman has delivered over 1,400 center fuselages to date, leveraging its state-of-the-art Integrated Assembly Line (IAL) at Palmdale. Inaugurated in 2011, the IAL is a cutting-edge facility that produces fuselages for all three F-35 variants on a single line, utilizing automated guided vehicles, robotic drilling, and on-site molding. Spanning the size of a football field, the facility operates 115 assembly stations and processes over ten million parts annually. Real-time production data enhances quality control and optimizes workforce efficiency, enabling Northrop Grumman to achieve this 30-hour production interval. This capability reflects a transformative approach to defense manufacturing, drawing inspiration from automotive industry innovations to meet the high tolerances required for advanced aerospace structures.
Beyond the center fuselage, Northrop Grumman plays a pivotal role in the F-35 program by supplying critical subsystems, including the AN/APG-81 and next-generation AN/APG-85 active electronically scanned array (AESA) radars, the AN/AAQ-37 Distributed Aperture System (DAS), and the AN/ASQ-242 Communications, Navigation, and Identification (CNI) avionics suite. The company also develops mission-planning software, pilot and maintenance training courseware, and supports low-observable technologies essential for the aircraft’s stealth profile. These contributions ensure technical consistency and secure supply chains, supporting the U.S. military and allied nations. The F-35 program, with over 1,200 aircraft delivered globally by mid-2025, faces intense demand, placing pressure on manufacturers to maintain high production rates. Northrop Grumman’s ability to produce a fuselage every 30 hours addresses this demand, ensuring timely deliveries to international partners and reinforcing the aircraft’s role in modernizing air forces worldwide.
This production milestone has far-reaching implications for U.S. air power and global defense. The F-35’s advanced stealth, sensor fusion, and networked capabilities make it a cornerstone of 21st-century deterrence, enabling operations in contested environments. Northrop Grumman’s manufacturing advancements not only bolster fleet availability for the U.S. Air Force, Navy, and Marine Corps but also support allied nations like the United Kingdom, Italy, and Australia, which rely on the F-35 to replace aging fighter fleets. The company’s collaboration with international partners, such as Rheinmetall in Germany for a new IAL facility set to produce up to 30 fuselages annually by 2027, further expands global production capacity. As geopolitical tensions and technological competition intensify, the ability to rapidly deliver fifth-generation fighters is a strategic advantage. Northrop Grumman’s achievement ensures the F-35 program remains on track to meet the U.S. goal of procuring over 2,400 aircraft, cementing its role in maintaining air dominance for decades to come.
