Shortlisted for the 2024 Financial Times Business Book of the Year

“Riveting…an exhilarating account of how the US defense industrial complex has started to come up to technological speed by tapping Silicon Valley. The chronicle of [the authors’] struggles is especially illuminating about the bureaucratic ‘antibodies,’ vested interests and pervasive mistrust between Silicon Valley and the Pentagon that they had to overcome. It also often reads like a thriller….Ultimately, though, Unit X is not about cool gadgets. It is about the need for the US—and by extension, the west—to maintain technological parity with its adversaries, and so deter war. Neither is a given.”
—Financial Times

“Revealing [with] a tone of urgency….the authors chronicle their experiences at the unit in its first years of existence. Along the way, they suggest how the tech gap got so wide and describe the attempts to close it.”
—Wall Street Journal

“Moves beyond what has been achieved to explore the prospects for more transformational innovation…The drama in the book, however, comes from what the authors call the “antibodies” in the system, as a sclerotic Pentagon bureaucracy and congressional staffers bent on protecting their privileges threatened to block the innovation unit’s progress.”
—Foreign Affairs

“Inspiring. A riveting reminder of how hard protecting our nation’s security can be, and how much depends on the ingenuity of a select few. A must-read.”
—Walter Isaacson, author of the New York Times bestselling biographies Steve Jobs and Elon Musk

“This book offers a window into how dinosaurs learn to innovate. With rich experience and vivid storytelling, Raj Shah and Christopher Kirchhoff show how it’s possible to coax creativity out of bureaucracies and fight for change in institutions designed to sustain the status quo.”
—Adam Grant, #1 New York Times bestselling author of Hidden Potential and Think Again, and host of the podcast Re:Thinking

“Riveting. Essential reading for understanding how technology will change the future of warfare—and the risks America faces if China's military innovates faster than ours.”
—Chris Miller, New York Times bestselling author of Chip War: The Fight for the World’s Most Critical Technology

“Rouses more curiosity about what happens next than anything I might have binge-watched. Unit X is terrifying but also hopeful.”
—Reid Hoffman, cofounder of both LinkedIn and Inflection AI and coauthor of the #1 New York Times bestseller The Startup of You

“Unit X pulls no punches. Fortunately, it also shows what's possible once you get out of the old-think box. While this is the story of the Pentagon's epiphany, it can apply just as well to businesses mired in habit and in need of resuscitation. And it's a fun read, too.”
—Vint Cerf, Winner of the A.M. Turing Award and cofounder of the Internet

“An illuminating, behind-the-scenes examination of the numerous, critical, and sometimes competing efforts inside the Pentagon to change the way it does business. An exceedingly important book!”
—General David Petraeus, US Army (Ret.), former Director of the CIA; and author of the New York Times bestseller, Conflict: The Evolution of Warfare from 1945 to Ukraine

“An unnerving tour de force. Unit X always feels high stakes, the ongoing tug of war it chronicles central to whether the nation prevails in the contests to come.”
—Admiral James Stavridis, (US Navy, Ret.); 16th Supreme Allied Commander of NATO; and author of 2054: A Novel

“Compelling. Those who put themselves in harm’s way to preserve freedom should consider Chris Kirchhoff and Raj Shah American heroes.”
—Rear Admiral Hugh Wyman Howard III, former Commander of DEVGRU (SEAL Team Six) and Naval Special Warfare

“Engaging and important. This is the story of a trailblazing Pentagon unit designed to harness American intellect, spur innovation, and maximize entrepreneurship so that peace will be preserved and the free world defended.”
—Lieut. General H.R. McMaster, U.S. Army (Ret.), former National Security Adviser, and New York Times bestselling author of Battlegrounds: The Fight to Defend the Free World

“Extraordinary. A gripping, firsthand account of the authors’ role in building and leading the innovation unit within the Department of Defense that is helping to get America ready for the future of warfare."
—Christian Brose, Chief Strategy Officer of Anduril Industries, Visiting Fellow at the Hoover Institution, and author of The Kill Chain: Defending America in the Future of High-Tech Warfare
