The Five Kings of the Pentagon

The Pentagon has a private sector.

Not a contractor base — a private sector. Between 2020 and 2024, more than half of every dollar the United States Department of Defense was allowed to spend went to private companies: about $2.4 trillion, according to researchers William Hartung of the Quincy Institute and Stephen Semler of Brown University's Costs of War project, in figures adjusted to constant FY2025 dollars. And within that river of money, five firms stand in the middle of the current and drink deepest: Lockheed Martin, RTX, Boeing, General Dynamics and Northrop Grumman — $771 billion in five years.

For perspective, that is more than twice what America spent on diplomacy, development and humanitarian aid over the same period: $356 billion. The country chose to invest over twice as much in weapons manufacturing as in peacebuilding. This investigation maps the five primes: how much they take, what they sell, and who runs them.

The $771 billion table

The Hartung–Semler report, published in July 2025, is the definitive ledger of the post-Afghanistan era. Its central finding: there was no peace dividend. The Biden administration increased Pentagon budgets after the 2021 withdrawal, and the flow continued. Fifty-four percent of DoD discretionary spending — contracts, not salaries, not operations — went to private firms. Of that, the lion's share went to the five primes, with Lockheed Martin alone securing $313 billion over five years.

The Defense News Top 100 ranking for 2025 confirms the pecking order within the five. Lockheed Martin: $72.1 billion in annual defense revenue, the world's largest defense company by a wide margin. RTX: $46 billion. General Dynamics: $39.4 billion. Northrop Grumman: $37 billion. Boeing's defense segment: $35.7 billion — sixth globally, behind Britain's BAE Systems at $36 billion, the first non-American in the ranking. The top 100 combined: $700 billion, up 11.3% year-on-year. The war business is not cyclical at the top. It is structural.

What each throne sells

Lockheed Martin is the air-and-missile empire: the F-35 Lightning II — the most expensive weapons program in history — plus PAC-3 and THAAD missile defense under multi-year framework agreements that provide demand certainty beyond annual appropriation cycles. Even here, the ground shifts: the Air Force cut planned 2026 F-35 procurements by half as attention turned to next-generation air dominance platforms.

RTX — the renamed Raytheon Technologies — is the missile house: Patriot systems in global demand (a $1.7 billion sale to Spain in December 2025 alone), with a Raytheon-segment book-to-bill of 2.27x in 2025, meaning orders ran at more than twice the pace of deliveries. Its stock surged 63% in 2025, the year's standout prime.

Northrop Grumman builds the things that must never be used: the B-21 Raider stealth bomber and the Sentinel intercontinental ballistic missile — the land leg of the nuclear triad — plus a $1.4 billion deal to integrate battle command systems across allied missile networks in Poland.

General Dynamics owns the sea and the land: Virginia-class submarines (a $12.4 billion contract) and Abrams tanks, cushioned by Gulfstream business jets — roughly 45% of revenue — which make it the least defense-pure of the five.

Boeing Defense is the wounded giant: the defense unit bled on fixed-price contracts — the KC-46 tanker most famously — running negative margins while the commercial side recovered. It remains the outlier of the five, and the one the Pentagon watches most nervously.

The five chiefs

Every pyramid has a head. At Lockheed Martin, James Taiclet — chairman, president and CEO — runs the world's largest defense company. At RTX, Christopher Calio, president and CEO, presides over the missile boom. At Northrop Grumman, Kathy Warden — chair, CEO and president — commands the nuclear-modernization franchise. At Boeing, Kelly Ortberg, president and CEO, inherited the defense unit's fixed-price wounds and the job of cauterizing them. At General Dynamics, Phebe Novakovic — chairman and CEO — runs the quietest of the five, the submarine-and-tank house that rarely makes headlines and always makes money.

Five Americans, five corner offices, one shared customer: the United States government. The primes are not vendors to the Pentagon. Vendors can be replaced. These are organs — and organs do not get voted out.
