Who Is Frank Kendall?
Frank Kendall III was born on January 26, 1949, in Pittsfield, Massachusetts. He is not simply a government official with a title. He is a trained engineer, a licensed attorney, and a former military officer all rolled into one remarkably experienced person.
He graduated from the United States Military Academy at West Point in 1971 as a distinguished graduate. He later earned a Master of Science from the California Institute of Technology, an MBA from Long Island University, and a law degree from Georgetown University. That kind of academic range is rare in any profession, let alone in national defense.
He served 11 years as an active duty Army officer before transitioning into senior civilian roles. He eventually retired from the U.S. Army Reserve at the rank of lieutenant colonel. His blend of technical depth and legal training shaped the way he made decisions throughout his entire career.
Frank Kendall’s Career Before the Air Force
Before taking charge of the Air Force, Frank Kendall already had a long and impressive record in both the private sector and the federal government.
In the private sector, he served as Vice President of Engineering at Raytheon Company, one of the largest defense contractors in the United States. He managed engineering operations across the company and directed internal research and development efforts. He also worked as a Managing Partner at Renaissance Strategic Advisors, a Virginia-based aerospace and defense consulting firm.
Within the government, Kendall held several important posts inside the Pentagon. He served as Deputy Director of Defense Research and Engineering for Tactical Warfare Programs in the Office of the Secretary of Defense. His most prominent pre-Air Force role came under President Barack Obama, when he served as Under Secretary of Defense for Acquisition, Technology, and Logistics from 2011 to 2017. In that position, he oversaw major weapons programs and shaped acquisition policy across all branches of the military. He received four Defense Distinguished Public Service Awards during his career, which is the highest civilian award the Secretary of Defense can grant.
He was also active in human rights work, serving on boards including Amnesty International USA and the Center for Victims of Torture, largely on a pro bono basis. That side of his career often gets overlooked but it says a lot about who he is as a person.
When Was Frank Kendall Secretary of the Air Force?
Frank Kendall officially became the 26th Secretary of the Air Force on July 28, 2021, and served until January 20, 2025. That is nearly four years leading one of the most complex and high-stakes departments in the U.S. military. source: The Roosevelt Group
In that role, he was responsible for organizing, training, and equipping the U.S. Air and Space Forces. He directed an annual budget exceeding $173 billion. He was accountable for the welfare of nearly 700,000 active duty, Guard, Reserve, and civilian Airmen, Guardians, and their families. The scale of that responsibility is genuinely hard to grasp without seeing the numbers.
What Did Frank Kendall Do as Secretary?
Driving Modernization for Great Power Competition
The single biggest theme of Frank Kendall’s tenure was modernization. He consistently argued that the Air Force needed to accelerate its transformation to stay competitive against near-peer adversaries, particularly China. He called it reoptimizing for great power competition and he made it the organizing framework for almost every major decision he made.
He pushed for investments in advanced weapons, smarter technology, better space capabilities, and more resilient air bases. He did not treat modernization as a slow, long-term process. He treated it as an urgent operational need that could not wait.
Launching the Collaborative Combat Aircraft Program
If you ask what Frank Kendall is most known for, most defense experts will point to the Collaborative Combat Aircraft program, widely known as CCA. This is a program to develop semi-autonomous uncrewed aircraft that fly alongside crewed jets in combat.
Kendall championed this program from the start and pushed it forward with urgency. Two contractors, Anduril and General Atomics, received contracts to produce aircraft under the first increment of the program. Kendall himself flew in an AI-controlled F-16 to better understand the technology firsthand. That flight drew widespread attention across the defense community.
The Air Force envisions a fleet of around 1,000 CCAs that will complement crewed fighters by carrying extra weapons, conducting reconnaissance, and performing electronic warfare missions. Kendall described CCA as the most transformative capability development of his tenure. Battle simulations consistently showed decisive advantages for the side equipped with CCAs.
Space as a Warfighting Domain
Kendall also oversaw the U.S. Space Force, which was still a young branch when he took charge. He pushed strongly for the Space Force to be treated as a genuine warfighting domain rather than simply a support function for ground-based operations. He advocated for more aggressive counterspace capabilities and ensured the Space Force received the attention and resources it needed to grow.
His Own Assessment of His Legacy
When Kendall reflected on his time as Secretary, he said his most important contribution was raising a sense of urgency around modernization. He believed the Air Force and Space Force needed cultural change as much as new hardware. He wanted the entire department to feel the pressure of the moment and act accordingly. source: LinkedIn · Frank Kendall
Frank Kendall After Leaving Office
Kendall left the Secretary role in January 2025 when the Biden administration ended. He moved into roles as a consultant and Senior Fellow at the Center for American Progress, continuing to engage with defense policy publicly.
However, his post-government period brought significant controversy. In August 2026, the Pentagon announced it had immediately revoked Frank Kendall‘s eligibility for access to classified information and barred him from holding any sensitive position. The Pentagon cited an alleged unauthorized disclosure of classified information about Air Force One’s capabilities to a media outlet.
Kendall denied the accusation directly. He told CNN that he had been extremely careful not to share anything classified and that no one had told him specifically what he was supposed to have revealed. He also noted that he had been openly critical of the Trump administration since leaving office in January 2025.
The controversy centered on reporting about a Qatari-gifted jet being considered for use as Air Force One, including concerns that it lacked key capabilities compared to the older presidential aircraft. Kendall had a deep history with the Air Force One program, having helped guide the selection of the Boeing 747-8 platform for the next generation of presidential aircraft back in 2015 while serving as the Pentagon’s acquisition chief.
No formal public charges had been filed at the time of this writing, and the situation remains disputed. The revocation of his clearance effectively ended his ability to contribute formally to classified defense work going forward.
