Northrop Grumman (NOC) Shares Drop 4% as Boeing Secures Navy’s F/A-XX Fighter Jet Deal

Key Takeaways

• Boeing secured a multi-billion-dollar Navy contract for developing the F/A-XX sixth-generation fighter aircraft.
• Shares of Northrop Grumman dropped approximately 4% during pre-market hours after losing the competitive bid.
• Boeing’s stock gained around 3% in early trading on the announcement.
• The win represents Boeing’s second sixth-generation fighter contract in 2025, following its Air Force F-47 victory over Lockheed Martin.
• The F/A-XX program is designed to eventually succeed the Boeing F-18 Super Hornet in carrier-based operations.

Boeing secured another major defense victory on Tuesday when the U.S. Navy selected the aerospace giant to develop its F/A-XX sixth-generation fighter jet, awarding the company a contract worth billions while leaving competitor Northrop Grumman empty-handed.

Shares of Northrop Grumman tumbled 4% to $482.94 during pre-market trading after the announcement. In contrast, Boeing’s stock surged 3% to $192.49 before regular trading commenced.

The outcome came as a surprise to many market observers who had anticipated Northrop Grumman would emerge victorious.

Investor expectations favored Northrop partly because Boeing had already captured the Air Force’s F-47 sixth-generation fighter contract earlier in 2025, defeating Lockheed Martin. Industry watchers believed the Pentagon might diversify its next-generation capabilities across multiple contractors.

That strategic thinking proved incorrect.

Understanding the F/A-XX Program

Specific details about the F/A-XX remain under wraps due to classification. The Pentagon hasn’t disclosed the program’s total budget, planned production numbers, or anticipated operational deployment timeline.

Available information indicates the aircraft will serve as the eventual replacement for Boeing’s F-18 Super Hornet platform. The new fighter is designed to significantly expand the operational reach of carrier-based strike groups.

Next-generation military aircraft feature advanced weapon integration, sophisticated software architectures, and enhanced stealth capabilities. These technological improvements come at substantial financial cost. The F-35 fifth-generation fighter, for reference, carries an acquisition price exceeding $100 million per unit, with lifetime maintenance costs ranging from $500 million to $700 million.

Defense Secretary Pete Hegseth and Deputy Secretary Steve Feinberg previously raised concerns about the F/A-XX initiative. They argued America’s defense manufacturing infrastructure lacked sufficient capacity to simultaneously support two distinct sixth-generation fighter programs.

Congressional lawmakers overruled those objections, approving hundreds of millions in funding to advance the Navy’s program.

Boeing’s Capacity Challenge

With Boeing now controlling both Air Force and Navy sixth-generation fighter developments, questions emerge about the company’s ability to staff both ambitious programs simultaneously.

J.J. Gertler, formerly with the Congressional Research Service, identified workforce availability as the critical limiting factor moving forward. “At some point the constraint becomes people,” Gertler explained, highlighting the dwindling availability of skilled engineers and technical personnel around Boeing’s St. Louis manufacturing hub.

Aviation industry analyst Richard Aboulafia suggested the contract loss won’t significantly damage Northrop’s business prospects. The defense contractor maintains substantial workloads with ongoing B-21 stealth bomber production and development of the Sentinel intercontinental ballistic missile system.

Nevertheless, Aboulafia emphasized that securing both contracts elevates Boeing to unprecedented dominance in the defense sector, describing the company as “masters of the new universe” among military contractors.

Boeing’s defense division has struggled financially in recent years. The unit reported a $128 million operating loss in 2025, though this represented considerable improvement from the $5.4 billion deficit recorded in 2024. The division hasn’t achieved annual profitability since 2021.

William Blair analyst Louie DiPalma characterized the Navy contract as a “milestone” achievement for Boeing’s struggling defense operations.

Boeing shares had already climbed 2% during Tuesday’s regular trading session prior to the contract announcement, recovering some losses from earlier in the week following the discovery of software issues affecting 737 MAX aircraft.
