Title

Assessing US defense industrial mobilization readiness for major conflict

Purpose

The Senate Armed Services Committee held this hearing to examine whether the United States is prepared to mobilize its industrial base for a large-scale, sustained conflict, drawing on lessons from Ukraine, the Cold War, and World War II. Three witnesses — John McGinn, Christine Michienzi, and David Berteau — testified on Defense Production Act authorities, acquisition practices, supply chain fragility, and workforce shortages. Members from both parties pressed the witnesses on reauthorizing the DPA, restarting mobilization planning, and the effects of recent budget disruptions, tariffs, and continuing resolutions on the defense industrial base. Begins at▶ 0:15:58

Who spoke

• Sen. Jack Reed (D-RI), Ranking Member▶ 0:17:08: Opened by warning that nations with strong militaries have lost wars due to weaker industrial capacity▶ 0:17:41, said the Ukraine war exposed U.S. industrial-base vulnerabilities▶ 0:18:12, and argued mobilization "does not occur overnight"▶ 0:19:27; later asked witnesses about the impact of recent workforce cuts, funding cuts, and tariffs on mobilization▶ 0:46:18.

• Sen. Deb Fischer (R-NE), Chair▶ 0:22:30: Presided over the hearing, pressed witnesses on limiting DPA use to clearly national-security-related investments rather than areas like clean energy▶ 0:41:15, and asked about the Pentagon's National Defense Industrial Strategy▶ 0:43:27.

• Dr. John McGinn, witness▶ 0:22:39: Said U.S. ability to win a major war is "very much at risk" absent bold action before "the balloon goes up"▶ 0:23:25; called for DPA reauthorization and use of underused Title VII voluntary agreements and National Defense Executive Reserve authorities▶ 0:25:15▶ 0:25:42; said defense spending has fallen from 5-6% of GDP during the Cold War to about 3% today, driving industry consolidation▶ 1:00:24.

• Dr. Christine Michienzi, witness▶ 0:29:23: Said the defense industrial base is fragile due to decades of prioritizing low cost over resilience▶ 0:29:50; identified DOD's acquisition behavior — not acquisition reform — as the root cause of supply chain problems, since programs rarely factor in industrial-base impact▶ 0:31:40; said obsolescence, handled reactively, was the main reason more Stinger and Patriot missiles couldn't be produced when the Ukraine conflict began▶ 0:33:42.

• Mr. David Berteau, witness▶ 0:35:20: Drew on his 1981-1993 Pentagon tenure during the Reagan buildup, saying a shared threat scenario between the White House, Pentagon, and Congress enabled mobilization funding▶ 0:36:45; noted the U.S. only kept enough business to sustain "2.5 manufacturers"▶ 1:02:14; said Franklin Roosevelt "did not face a single continuing resolution" during the WWII buildup▶ 0:58:21.

• Sen. Mike Rounds (R-SD)▶ 0:50:58: Asked about DOD's operational-plan assessment requirement for concurrent, multiple-theater conflicts and what shortfalls the department should highlight▶ 0:51:24.

• Sen. Angus King (I-ME)▶ 0:56:09: Questioned whether defining scenarios and strategy is done too broadly to be useful▶ 0:56:09; got witnesses to agree continuing resolutions harm industrial-base preparation▶ 0:58:13 and that allies are essential since the U.S. "cannot do this by ourselves"▶ 0:59:39.

• Sen. Tim Sheehy (R-MT)▶ 1:02:35: Argued the Pentagon itself created industrial consolidation and questioned whether government can fix it, contrasting U.S. free-market production strength with centralized WWII-era Axis defense ministries▶ 1:03:04; cited SpaceX having to sue the government over procurement rules▶ 1:05:31.

• Sen. Tim Kaine (D-VA) [0:56:14 / 0:58:41... actually see below]: Focused on workforce shortages tied to shipbuilding and declining birthrates, and asked witnesses for workforce strategies including joint approaches with allies▶ 0:59:04.

Key moments

• McGinn: DPA Title III purchase commitments are currently blocked because DPA funds are appropriated with expiring procurement dollars rather than non-expiring traditional DPA appropriations▶ 0:25:15.

• Michienzi: DOD is often only 1-2% of total demand for critical items, yet programs routinely default to the cheapest — often Chinese or adversarial — source rather than more secure suppliers▶ 0:33:09.

• Berteau recounted DPA lapsing once before, right when Saddam Hussein invaded Kuwait, calling it "a dangerous time to do it"▶ 0:48:29.

• Sen. King pressed all three witnesses to explicitly agree continuing resolutions are not part of the solution; Berteau cited FDR never facing one during the WWII buildup▶ 0:58:13▶ 0:58:21.

• McGinn said U.S. defense spending has dropped from 5-6% of GDP in the Cold War to about 3% today, directly driving supplier consolidation▶ 1:00:24; Berteau added the government "only buys enough to keep 2.5 manufacturers in business"▶ 1:02:14.

• Berteau: government contractor compliance requirements dropped the number of contractors from 51 to five during the WWII-era buildup era comparison, citing at least 15-20 regulatory items that add cost and time without improving outcomes▶ 1:03:59▶ 1:04:59.

• Sen. Sheehy noted SpaceX had to sue the government to get equipment approved that didn't fit "byzantine regulations," illustrating barriers to nontraditional contractors▶ 1:05:31.

• Michienzi said obsolescence planning failures were the main reason production of Stinger and Patriot missiles couldn't be ramped up when Ukraine aid began▶ 0:33:42.

• Witnesses agreed mobilization planning ended in the early 1990s and needs to be restarted across the U.S. government▶ 0:26:43▶ 0:49:27.

• Berteau: economic price adjustment clauses meant to offset inflation have rarely been used, leaving shipyard welders earning less after a year than they could make at Walmart or Costco▶ 1:10:21▶ 1:10:52.
