Sharper | Securing America’s Defense Industrial Base

Six months of war with Iran has depleted America’s munitions capacity, leaving stockpiles of interceptors and precision weapons dangerously low and demand above the replacement rate of production. The United States urgently needs new strategies to prepare the defense industrial base (DIB) for present and future challenges. In this edition of Sharper, CNAS experts analyze how the United States can revitalize America’s DIB, with policy recommendations aimed at the military, Congress, and industry to harness the collective potential of America’s defense sector.

Series | The New American Defense Industrial Base

The U.S. DIB has long struggled with persistent challenges across the supply chain—a danger exacerbated by the Iran war’s depletion of critical munitions stockpiles. In the commentary series The New American Defense Industrial Base, 14 guest authors, including former senior military leaders, venture capitalists, and start-up executives, offer their perspectives on reforming the DIB, leveraging their extensive experience to deliver timely recommendations for the public and private sector.

Report | Drones, Missiles, and the U.S. Munitions Shortage

Although drones have been used extensively in recent global conflicts, critical questions linger about their value to high-stakes U.S. military operations. In Drones, Missiles, and the U.S. Munitions Shortage: The Role of Affordable Mass in a Taiwan Conflict, authors Philip Sheers and Stacie Pettyjohn examine the role of “affordable mass” in a full-scale invasion of Taiwan, a scenario in which the United States could be required to strike more than 2,000 targets. Exquisite munitions stockpiles must be replenished, they argue, but supplementing these capabilities with lower-cost weapons will help reverse the U.S. inventory disadvantage and block China from achieving its operational objectives.

Report | Stuck in the Cul-de-Sac: How U.S. Defense Spending Prioritizes Innovation over Deterrence

Disproportionate investments in long-term developmental programs have left the Pentagon less able to meet the need for near-term deterrence. As China’s military buildup accelerates, the need to balance these two time horizons is becoming increasingly critical. In Stuck in the Cul-de-Sac: How U.S. Defense Spending Prioritizes Innovation over Deterrence, authors Carlton Haelig and Philip Sheers analyze the pitfalls of the fiscal year 2026 defense budget, laying out how the United States can avoid a costly mistake by closing near-term capability gaps while sustaining modernization plans.
