The U.S. defense industry, traditionally dominated by a handful of giants born from post-Cold War consolidation, is on the verge of a radical transformation. The current trend points to the fragmentation of these large conglomerates, seeking greater specialization, agility, and, fundamentally, increased stock market value. Companies like L3Harris Technologies and Honeywell International have already set the standard, and the pressure is now on other key players such as Lockheed Martin and, potentially, Boeing, General Dynamics, and RTX. The Pioneers of Fragmentation: L3Harris and Honeywell
L3Harris Technologies, which calls itself the sixth largest “prime contractor” in the United States, is a clear example of this new dynamic. The company, currently structured into three main divisions (Space & Mission Systems, Communications and Spectrum Dominance, and Missile Solutions), announced plans to separate these units in 2026. This strategic move is not isolated. Previously, in 2025, Honeywell International executed a similar maneuver by splitting into three independent entities: Honeywell Automation, Honeywell Aerospace, and Solstice Advanced Materials, demonstrating the viability and market appetite for these spin-offs.
Will Lockheed Martin be next?
The industry and stock market analysts have their eyes on Lockheed Martin. For years, there has been a latent expectation about the possible breakup of large companies like Boeing, General Dynamics, and even the relatively new RTX. However, forecasts from several North American stock market analysts suggest that 2026 could be a decisive year, marking the end of the era of the large defense companies inherited from the post-Cold War period as we know them.
The consensus among analysts, investors, and consultants is that breaking up these leading companies into smaller firms could unlock significant stock market value. This pursuit of higher market valuations aligns with the U.S. Department of Defense’s (DoD) interest in rebuilding the defense “midmarket.” The DoD believes that the more agile and flexible management typical of smaller companies will allow for a rapid increase in production volumes, a critical need highlighted by recent global conflicts.
The key to this interest lies in the fact that companies like Lockheed and RTX conceal business units with enormous growth opportunities beneath their diversified product portfolios, particularly in the production of specific products such as rockets and missiles.
Why the Obsession with Smaller, Specialized Companies?
Investor interest has surged in business units related to the aerospace sector, especially the space program and the production of rockets and missiles. These areas are positioned for robust growth. Investors are particularly interested in the potential breakup of companies focused on space and missiles, driven by the vision for the future Golden Dome program and the urgent need to rebuild missile and rocket stockpiles—a demand created by the war in Ukraine and the conflict between Israel and Iran.
The emblematic case of Lockheed Martin
Lockheed Martin faces a structural challenge. The F-35 program represents approximately a quarter of its annual revenue, but production is projected to peak around 2030, at which point the bulk of orders will have been delivered. At the same time, the company has failed to secure key contracts in recent years, such as the USAF’s F-47, the US Army’s Future Long-Range Assault Aircraft (FLRAA), or significant new business opportunities.
Additionally, Lockheed’s corporate leadership has sown doubts among investors by focusing a significant portion of its attention on the 5G program, a proposal to improve connectivity on the battlefield, which, for many investors, dilutes the focus on its most promising growth assets.
Recent high-intensity conflicts have confirmed a paradigm shift in the use of aerospace power, favoring a “market shift” toward a large number of unmanned and decentralized aircraft, such as the Collaborative Combat Aircraft program. This context paints an uncertain future for the monolithic Lockheed Martin. For the markets, dividing the company into independent businesses is the clearest path to generating significant shareholder value within the new defense and space technology ecosystem, following the pattern established by General Electric, Honeywell, and L3Harris.
L3Harris: A leader in corporate breakup
L3Harris has positioned itself at the forefront of this trend, capitalizing on investor interest in defense and space technology. The company, which two years ago reached an agreement with an investor to explore strategic alternatives, is now capitalizing on the resulting opportunities. Examples include its plans to sell parts of its Space Propulsion and Power Systems group to private equity investor AE Industrial Partners, and the spin-off of its Missile Solutions business, which will even include a $1 billion equity stake from the Pentagon.
Washington’s long-term strategic vision
Beyond the specifics of the current administration, stock market analysts agree that these corporate divisions are driven by a bipartisan belief deeply rooted in Washington: that large, traditional suppliers became over-consolidated after the Cold War.
Faced with the urgent need to act quickly, produce more weaponry, and the rise of more agile space and defense technology companies like SpaceX (which view hardware as a vehicle for services), both US politicians and military officials are seeking greater responsiveness from major contractors.
Paradoxically, if the administration’s restrictions on large dividends and executive bonuses take effect this year, analysts predict that tens of billions of dollars that would otherwise have been shareholder profits will be redirected toward mergers and acquisitions, particularly vertical integration. In this scenario, large companies would seek to gain greater control and value over their supply chains, a move that, while distinct from fragmentation, still responds to the pressure for efficiency and production resilience. A Constant Cycle of Evolution
The history of the defense industry is a constant cycle of restructuring. A century ago, Boeing was a conglomerate that encompassed everything from what is now United Airlines to parts of the Tier 1 supplier RTX. Over the years, it has split and merged multiple times, including the acquisition of McDonnell Douglas in the 1990s and the recent reacquisition of Spirit AeroSystems.
The investors money, and the Pentagon’s strategic interests are driving a new era of specialization and business agility. The lesson of this trend is clear: in the defense industry, as on Wall Street, “What matters is money, health comes and goes…”
