The Warm-Base Turn: How the West Pays Industry to Hold Capacity It May Never Fire

Western defence budgets are climbing, but the sharper 2026 development is what governments now buy: standing, surge-ready capacity bought with multiyear demand guarantees and state credit.

The headline on Western defence is the money: NATO's 5-percent-of-GDP pledge for 2035, a 1.5-trillion-dollar US request for fiscal 2027. Read as spending, the conclusion is to buy more weapons. Beneath it sits something different. Governments have begun paying industry not for finished missiles but for the option to make them at scale, underwriting warm lines, multiyear demand and capacity that may sit idle until a war needs it. The question is moving from how much is appropriated to whether the promise of future orders is credible enough to make a firm hire, tool and qualify suppliers. The inflection runs to 2029.

Signal Identification

This is a change in the instrument of rearmament, from buying end-items to buying standing capacity. The load-bearing variable is the credibility of demand: a warm line is worth only as much as the orders behind it. The state risks absorbing capacity and inventory exposure it cannot easily reverse, while the lower tiers that set delivery times stay underfunded.

What's Changing

The clearest tell is in the numbers and their scheduling. The fiscal 2027 request seeks about $70.5 billion for missiles, a 188 percent jump on the $24.4 billion enacted for fiscal 2026, with Tomahawk alone up 1,327 percent (Breaking Defense, 13/04/2026). No vendor can build that in a year. Roughly 55 percent is routed through reconciliation so it stays available for years, letting the government tell a contractor "we already have the funding. We can now guarantee this to you" — better, one analyst notes, than multiyear procurement because it does not wait on future appropriations.

The financing tools follow the same logic. The Office of Strategic Capital, a Pentagon lender, is requesting about $20.2 billion for fiscal 2027, more than ten times the under $1.5 billion of a year earlier (DefenseScoop, 06/04/2026). Its template is the MP Materials deal: a 10-year offtake with a guaranteed price floor, a $150 million OSC loan and up to $1 billion in private financing, meant to "create some stability and demand" (Federal News Network, 30/03/2026). Europe runs the pooled version: a EUR 1.5 billion EDIP programme directs more than EUR 700 million into counter-drone, missile and ammunition output and EUR 240 million into joint procurement (European Commission, 30/03/2026).

Disruption Pathway

The pathway runs in two stages. To begin with, governments swap one-off purchases for standing commitments — multiyear contracts, capacity agreements, price floors, loan guarantees — to de-risk the capital a firm must sink before any weapon ships. The Council of Economic Advisers frames this as a "hold-up problem": firms fear the single buyer will renegotiate once they have invested, so demand must be made credible, and the One Big Beautiful Bill Act expanded the OSC to back up to $100 billion in loanable funds (Council of Economic Advisers, 01/04/2026). Then that capacity must be paid to stay warm between conflicts, turning a cyclical order book into a subsidised utility.

Stress concentrates at two points. One is the sub-tier, where solid rocket motors, seekers and energetics set the real clock; CSIS judges that with funding now bipartisan, "the problem today isn't money; it's time", with lead times of 34 to 39 months and Tomahawk, THAAD and Patriot stocks taking three or more years to replace (Center for Strategic and International Studies, 27/05/2026). The other is the public balance sheet, now carrying inventory and capacity risk. The state becomes anchor customer and lender at once, while primes scale toward surge rates — Lockheed aims to roughly quadruple THAAD capacity and lift PAC-3 toward 2,000 interceptors a year — that pay off only if the orders arrive.

Why This Matters

For boards and CFOs of primes, the demand signal is now a balance-sheet input, not a forecast: a guaranteed multiyear order changes the hurdle rate on a new line, and a quiet de-scoping of reconciliation money can strand it. For defence and budget ministries, the task moves from annual procurement to managing long-dated capacity commitments that outlast a single government. For investors, state credit alongside private capital reprices risk across the supplier base and rewards firms at genuine bottlenecks. Who funds the warm lines in a quiet year is now a recurring fiscal question.

Decision-action posture for this signal: Prepare — the instruments are live and large, but their durability is unproven until 2027-2029 deliveries confirm whether demand guarantees convert into capacity; set capability and capital plans against named triggers.

Implications

On the available evidence, this is a durable change in defence economics, not a wartime spike. The Iran campaign that drained Western magazines supplied the urgency (Center for Strategic and International Studies, 21/04/2026), but the instruments now being built — demand guarantees, EDIP pooling, a tenfold-larger state credit programme — are designed to persist between conflicts. The window is 2027 to 2029, when promised capacity becomes delivered rounds or exposes the gap between goals and output. Firms at real bottlenecks that can absorb state capital gain; those treating the order book as a one-off surge risk over-building into demand a later budget withdraws.

Early Indicators to Monitor

• Definitised production contracts, not just capacity agreements, signed against the FY2027 PAC-3, THAAD and Tomahawk requests.
• OSC executing further loans or guarantees to munitions and energetics suppliers beyond the MP Materials template.
• EDIP's initial calls translating into awarded contracts for warm or surge capacity in named European plants.
• Appropriations sustaining the reconciliation-funded munitions tranche in later cycles.
• Explicit "warm base" or capacity-retention line items appearing in US or EU budget justifications.

Disconfirming Signals

• Capacity agreements lapse without follow-on production orders, and capacity goals are quietly dropped.
• Reconciliation munitions money is rescinded or reallocated, breaking the multiyear demand promise.
• OSC's enlarged credit request is cut back toward prior-year levels.
• Primes decline to invest their own capital despite guarantees, citing unreliable forward demand.
• Sub-tier failures persist or worsen, showing guarantees never reached the binding layer.

Strategic Questions

• Do we invest balance-sheet capital in surge capacity now on a government guarantee, or wait for definitised orders?
• Should we anchor at sub-tier bottlenecks where guarantees are scarce, or compete at the prime layer?
• At what evidence threshold does the warm-base signal move from Prepare to Decide for our capital plan?
