Three defense stories broke this week that describe one failure: the industrial systems the West built to fight the last war cannot produce fast enough for the wars actually underway.

A factory that can't keep up

Ukraine's war has grown more fluid, with intense fighting over air defense and a Black Sea campaign that has bled Russian naval power, according to analysts Dara Massicot and Michael Kofman on the War on the Rocks podcast. Despite reports suggesting otherwise, Ukraine almost certainly cannot manufacture its own PAC-3 interceptor missiles, the analysts said — a sign that sophisticated air defense cannot be conjured domestically at the pace Kyiv needs. Kyiv is also weighing a new round of Russian mobilization and absorbing the political fallout from its defense minister's dismissal, per the same discussion.

The Pentagon faces a version of the same bind: it must simultaneously mass-produce legacy systems and innovate at scale to make those systems obsolete, according to the American Enterprise Institute. AEI argues the second task matters more, because an acquisition system built to replenish yesterday's weapons is unsuited to outpacing tomorrow's.

China isn't waiting for anyone's acquisition reform

While Western planners debate process, China has spent years converting civilian ferries into vehicles for launching amphibious armor, building specialized gear to land forces without conventional ports, hardening dozens of air bases, and expanding the missile forces meant to deter or defeat a U.S. intervention, according to War on the Rocks. That buildup runs through a civilian-adjacent, dual-use industrial base — the fast, flexible production Western militaries lack.

A recurring school of thought argues China's capabilities are overstated and a Taiwan invasion remains beyond the People's Liberation Army's reach, citing its political character, lack of combat experience, and institutional shortcomings, per the same War on the Rocks piece. Hypothesis: if that skeptical camp is right about institutional fragility, the buildup alone may not translate into usable combat capability. Against this: infrastructure and missile inventories are durable assets that outlast any single leadership generation or doctrine — hardware is harder to walk back than an argument about readiness.

Betting on software instead of steel

Shield AI, founded in 2015 by former Navy SEAL Brandon Tseng, builds Hivemind autonomy software along with the V-BAT and X-BAT autonomous aircraft, betting the AI pilot matters more than the airframe, according to Tseng in a War on the Rocks interview. Autonomy stacks can iterate and redeploy at software speed, while a new manned aircraft program takes a decade. A similar bet underlies NODA AI, which builds mission-command systems for autonomous forces and sponsored the same Massicot-Kofman podcast on the Ukraine war — a sign of where investment capital is flowing as the drone war grinds on.

A Council on Foreign Relations report argues the United States needs to reshape its defense production to counter China, per CFR. Together with AEI's diagnosis, the message from two Washington institutions converges: the fix isn't more of the current system, it's a different one.

Hypothesis: Ukraine's missile shortfall, China's dual-use invasion infrastructure, and the Pentagon's acquisition strain are three symptoms of one cause — legacy defense-industrial systems built for slow, exquisite production cannot match the speed and scale either adversary or ally now needs, making commercial and autonomous investment a substitute for reform rather than an add-on to it. Supporting this: all three cases involve actors reaching outside traditional procurement — Ukraine improvising air defense, China leaning on civilian shipping, and U.S. startups selling software over hardware. Against this: it remains unproven that autonomy alone can replace mass in a war that has also shown, in Ukraine's grinding attritional fighting, how much raw materiel still matters.

Watch for whether Russia announces a new mobilization round, how Ukraine's reshuffled defense ministry handles procurement, and whether the CFR's production recommendations gain traction in Washington before the acquisition debate becomes moot.
