The 39-day campaign structurally drew down the US and allied arsenal and opened a multi-year procurement supercycle a ceasefire does not close. CSIS found ~50% of Patriot and >50% of THAAD expended; replenishment runs to 2029–2030. The investable edge is durability — order books are ceasefire-insensitive — tempered by a caveat that some defense equities ran ahead of confirmed demand.
The 39-day campaign structurally drew down the US and allied arsenal and opened a multi-year procurement supercycle that a ceasefire does not close. CSIS's Last Rounds audit found ~50% of Patriot, >50% of THAAD and 45% of PrSM expended, with GCC+Israel Patriot stocks down ~86%; replenishment runs to 2029–2030. The supply response — PAC-3 600→2,000/yr, THAAD 96→400/yr, doubled Aster lines — is real but backlogged, and a three-front competition (Iran/Israel, Ukraine, Indo-Pacific) means every interceptor off the line is pre-booked. Global military spending already hit a record $2.887tn (2.5% of GDP); NATO set a 5%-by-2035 target. Two new dual-use chokepoints emerged: subsea cables (Gulf the highest-risk zone of 25; ASN force majeure) and a thin mine-countermeasures base. The investable edge is durability — order books and replenishment timelines are ceasefire-insensitive — tempered by the caveat that some defense equities ran ahead of confirmed demand in 2025.
| System | Drawdown / usage | Replenishment |
|---|---|---|
| Patriot interceptors | ~50% of US inventory | full replacement mid-2029 (FY27: 3,203) |
| THAAD interceptors | >50% of inventory | deliveries from mid-2029; complete end-2029 (FY27: 857) |
| Precision Strike Missile (PrSM) | 45% of inventory | deliveries from ~March 2030 (34-mo lead) |
| Tomahawk | >1,000 fired | full restoration ~late 2030 (<200/yr produced) |
| SM-3 / SM-6 (Navy/MDA) | SM-3 firings >80 | not to prewar until early 2029 |
| GCC + Israel Patriot stocks | ~86% over 39 days | — |
The first 16 days of "Operation Epic Fury" alone saw 402 Patriot interceptors fired by US forces. The three-front stockpile competition (Iran/Israel, Ukraine, Indo-Pacific) means every new PAC-3 MSE off the Camden, Arkansas line is functionally booked by CENTCOM/INDOPACOM through ~2029.
| Program | Capacity change | Detail |
|---|---|---|
| Lockheed Patriot PAC-3 MSE | ~600 → 2,000 units/yr by 2030 | 7-year framework signed Jan 2026; 620 delivered in 2025 |
| Lockheed THAAD | 96 → 400 interceptors/yr | quadrupled framework, signed Jan 29, 2026 |
| MHI / Raytheon SM-3 Block IIA | ~4x to ~100/yr | — |
| Raytheon Tomahawk | <200 → >1,000/yr target | — |
| MBDA Aster (SAMP/T NG) | production doubling through 2026 | Denmark €1.47bn for 4 batteries (Apr 21, rejected Patriot) |
| Diehl IRIS-T SLM/SLS | €1.5bn expansion → 16 batteries/yr by 2028 | reported near-100% intercept over 250+ engagements |
Global military expenditure reached a record ~$2.887tn in 2025 (+2.9% real, 2.5% of GDP — highest share since 2009), the 11th straight year of growth. US spending fell 7.5% to $954bn in 2025 but Congress approved >$1tn for FY2026, with Trump's FY2027 proposal at $1.5tn (Golden Dome, AI, new battleships). The EU drove ~50% of 2025 global growth; NATO's June 2025 Hague Summit set a 5%-of-GDP target (3.5% core + 1.5% related) by 2035.
01 Arsenal Drawdown and the Procurement Supercycle — CSIS Last RoundsDefense / Structural The highest-confidence defense finding is CSIS's Last Rounds audit (April 24, 2026) of what the 39-day Iran air campaign cost the US arsenal: ~50% of Patriot interceptor inventory, >50% of THAAD, and 45% of Precision Strike Missile expended; over 1,000 Tomahawks fired; GCC+Israel Patriot stocks drawn down ~86%. Replenishment runs to mid-2029 (Patriot), end-2029 (THAAD) and ~late 2030 (Tomahawk). Framework contracts signed before Day 1 are now under acute demand pull: Lockheed PAC-3 MSE scaling 600→2,000/yr by 2030, THAAD 96→400/yr, MHI/RTX SM-3 4x, MBDA Aster 2x. The multi-year backlog is ceasefire-insensitive — deliveries are booked through 2029–2030 regardless of when fighting stops. high
02 Subsea Cable Weaponization and Mine-Clearing DemandDefense / Dual-Use The Persian Gulf scored 4.6/5.0 — the highest of 25 global cable landing zones — on Starboard's 2026 Cable Risk Index; ≥17 cable systems transit the Red Sea/Persian Gulf and ~7 pass through Hormuz. Iran's IRGC-linked Tasnim published Gulf cable maps (April 22) and floated a permit/'protection fee' regime; Alcatel Submarine Networks declared force majeure (March 12), indefinitely pausing the 2Africa Pearls Gulf extension. Deepwater repair windows average ~40 days (open-ended in a conflict zone), and resumed work requires re-scanning the seabed for ordnance. On mines, Iran's Hormuz threat triggered allied minesweeping mobilization (Netherlands deployed May 27; Lithuania weighing support) against a thin global mine-countermeasures base. Counter-UAS, EW and satellite ISR rose as priorities after the Barakah strike. medium
03 Global Defense Spending — Record $2.887tn and the NATO 5% PivotDefense / Macro Global military expenditure hit a record ~$2.887tn in 2025 (+2.9% real, 2.5% of GDP — the highest share since 2009), the 11th straight year of growth. US spending fell 7.5% to $954bn in 2025 but Congress approved >$1tn for FY2026, with Trump's FY2027 proposal at $1.5tn (Golden Dome, AI, new battleships). The EU drove ~50% of 2025 global growth; NATO's June 2025 Hague Summit set a 5%-of-GDP target (3.5% core + 1.5% related) by 2035. Named order flow underscores the pull: a $24.3bn / 300-aircraft Lockheed F-35 contract and a $3.7bn RTX GEM-T order to Ukraine (April 2026). high
The procurement supercycle continues — backlogs and replenishment are multi-year and ceasefire-insensitive (CSIS: deliveries to 2029–2030). Order-book durability favors the primes; reconstruction/resilience EPCs and grid-hardening enter tender.
Air/missile defense, mine-clearing, cable security and ISR all surge; the interceptor stockpile crisis is structural through 2029–2030. Beneficiaries: Lockheed/RTX/MBDA/Rheinmetall, minesweeping navies, cable-monitoring vendors.
Subsea cable defense, DAS/SoP fiber-sensing, naval ISR and repair-ship capacity become procurement priorities. Repair windows of 40+ days and a small, aging global repair fleet are the binding constraint.
Layered air defense converts from episodic to permanent baseline procurement (Golden Dome, GCC integrated air defense); counter-UAS, EW and hardened-infrastructure spend step up; the three-front competition intensifies.
Capability-anchored, not stock calls: Lockheed Martin (Patriot/THAAD/F-35; a $24.3bn 300-aircraft F-35 contract), RTX (Patriot GEM-T, SM-family, Tomahawk; a $3.7bn April GEM-T order), MBDA/Diehl/Rheinmetall (European air-defense scale-up) and MHI (SM-3, AMRAAM). Order books are backlogged to 2029–2030, making demand durable across a ceasefire.
Cable-monitoring (Starboard-type), subsea-cable repair-ship operators, DAS/SoP fiber-sensing, naval ISR and satellite redundancy benefit from cable weaponization; mine-countermeasures vendors and minesweeping navies from the Hormuz mine threat; counter-UAS/EW from the Barakah-style drone risk.
European defense equities cooled in 2026 — the Stoxx Europe Aerospace & Defence index was −1.2% YTD vs +4.8% for the Stoxx 600, and Rheinmetall (up ~400% over three years) missed Q1 earnings. The industrial demand is real, but valuations ran ahead of confirmed demand. Equity snapshots are context, not anchors.
The conflict's damage profile (QatarEnergy LNG 3–5-year repair; desalination strikes; cable force-majeure; the Barakah generator fire) is generating a resilience-rebuild premium rather than like-for-like reconstruction. Rebuilds favor distributed, hardened, redundant capacity — a double-digit-percent capex premium over baseline, justified by demonstrated single-point-of-failure risk.
GCC near-total desalination dependence (Qatar 99%, Bahrain 90%+) and integrated power-and-water architecture push rebuilds toward distributed, hardened, redundant capacity; the Barakah strike underscores backup-power and grid-islanding investment. Water-tech EPCs and HVDC/storage OEMs benefit.
The indefinite 2Africa Pearls pause and reroute through older systems drives route diversification, repair-ship capacity and DAS/SoP fiber-sensing. Repair-ship scarcity (a small, aging global fleet) is the binding constraint; resumed work must re-scan the seabed for ordnance.
The ~86% GCC Patriot drawdown converts air defense from episodic to permanent baseline procurement (Golden Dome, GCC integrated air defense) with multi-year delivery backlogs.
KEPCO, Westinghouse and Rosatom are positioned for security-hedge baseload as civilian nuclear is repriced (see /markets/energy).
Timeline: Reconstruction tenders 2026–2028; the resilience-capex premium persists through any ceasefire given multi-year repair windows (QatarEnergy LNG 3–5 years; cable repair open-ended; interceptor replenishment to 2029–2030). · Full infrastructure resilience →
