Petraeus: $55 Billion Drone Investment Won’t Buy a Fighting Force Without Doctrine

General David Petraeus and Isaac C. Flanagan responded to the President’s FY27 Budget Request’s massive increase (24,000% y-o-y) in autonomous warfare spending in an opinion piece for The Hill titled “The Pentagon could be about to make a $55 billion mistake.”
The Doctrine Gap
Petraeus and Flanagan’s central argument is about institutional readiness. The Pentagon’s $54.6 billion commitment to autonomous warfare is historically significant, but history shows how hardware investment without corresponding doctrinal development leads to waste and failure.
“The lesson was clear: A drone without doctrinal concepts for employment, substantial force structure changes, trained operators and units, educated leaders, maintenance systems, intelligence integration, and personnel policies is not a weapons system at all — it is an asset on a spreadsheet.”
Lessons from the Predator
Think back to the Predator drone in the early years of the wars in Afghanistan and Iraq. When the military scaled drone operations there, the bottleneck was not the aircraft but the 150-person support structure each platform required, and the years it took the Air Force to build the training pipelines and institutional frameworks to support it.
“As Secretary of Defense Bob Gates observed, the biggest challenge with unmanned systems was manning them.”
We’re Not There Yet
Today, less than two percent of the autonomous warfare investment is directed toward doctrine and integration. No joint framework exists for commanding autonomous formations at scale. Training pipelines are not yet producing leaders capable of encoding commander intent into machine-executable parameters. The feedback loops that have made Ukraine’s drone warfare so adaptive do not yet have a structural equivalent in the U.S. system.
The thing is, investment is good. But the problem is sequencing and proportionality. Russia is adapting under live combat conditions. China is studying the results. The U.S. risks outspending both while falling behind in the dimension that will ultimately determine effectiveness.
Instead, we have to make sure the money has the institutions to back it up and people to make it go far.
What Congress Should Do
Their ask of Congress is pretty straightforward:
“First, it should direct and fence at least 5 percent of the funding for doctrine, training, and force design.
Second, it should include continuous feedback in acquisition processes, rather than relying on static contractual requirements.
Third, it should require periodic reporting on adaptation cycles — how quickly operational lessons are incorporated into doctrine, training, and procurement.”
