Karman Space & Defense Names Jon Rambeau as Chief Executive Officer

Rambeau is a 30-year, proven defense leader with a track record of driving results through innovation and technology – pushing the boundaries of what’s possible to solve complex problems for our nation and allies around the globe. He has held C-suite and senior executive roles with two of the world’s top defense contractors, most recently as president of the $8 billion Communications & Spectrum Dominance segment for L3Harris Technologies, a disruptive innovator in the global defense ecosystem. In this role, he led an extensive portfolio that included electronic warfare, advanced communications, threat sensing and targeting, and integrated vision systems. He served previously as the president for the $7 billionIntegrated Mission Systems segment.

Prior to his time with L3Harris, Rambeau spent more than 25 years at Lockheed Martin, where he held senior executive roles across a broad spectrum of defense capabilities. He served as Vice President and General Manager of Integrated Warfare Systems and Sensors, where he led missile defense, radar, shipbuilding, directed energy and combat system integration programs; Vice President of C6ISR, overseeing undersea, cyber, electronic warfare and command and control capability delivery; Vice President and General Manager of Training and Logistics Solutions, where he championed innovative solutions for live, virtual and constructive training; Vice President of F-35 International Programs; and Vice President for Technology Transition, where he advanced cutting-edge directed energy and nanoscale material technologies from the lab into customer capabilities.

“The Board conducted a rigorous search for a CEO who can lead Karman through this next period of significant growth, where we will continue to leverage advanced technology, scale and our position as a trusted partner to solve critical supply chain challenges for the Department of War and commercial space customers,” said David Stinnett, chairman of Karman’s board of directors. “Jon emerged as the clear and unanimous choice to lead Karman, with the right combination of experience, capabilities and a passion for innovation to drive continued profitable growth.”

“Tony Koblinski led Karman on an incredibly successful growth trajectory since its founding in 2020, culminating in its IPO, four subsequent acquisitions, and its position as a trusted partner by more than 80 customers across both space and defense markets,” Stinnett added. “We thank Tony for his relentless commitment to Karman, our customers, and our shareholders, and we look forward to his continued contribution as a director on our board.”

“I am honored and humbled to assume the role of CEO, and lead the company through its next phase of growth,” said Rambeau. “This is a unique opportunity to enable the success of every space and defense prime, from long-established industry leaders to a broad spectrum of new entrants, leveraging Karman’s technology-forward capabilities and innovative team.

“I look forward to working collaboratively with Karman’s employees and leadership to maintain our trajectory of profitable growth, manufacturing capacity expansion, and consistently delivering customer value. At a moment when rapid solution delivery is critical to the nation, Karman remains positioned to respond. I’m grateful to Karman’s board for their confidence in me, and for Tony’s years of dedicated service that have brought the company to this market-leading position.”

“I could not be prouder of the Karman team and what we have accomplished in such a short time,” said Koblinski. “With a deep and capable leadership bench supporting him, Jon has the experience, people and the infrastructure to continue creating significant shareholder value.

“After more than 40 years of business leadership, I look forward to spending more time with my family while still supporting Karman’s success as a director. I am confident in Jon’s ability to lead Karman and in the Karman team’s relentless dedication to supporting our customers’ success.”

Rambeau holds a Bachelor of Science degree in mechanical engineering from Drexel University and a Master of Science in technology management from the Wharton School and the University of Pennsylvania’s College of Engineering and Applied Science.
