If you own US defense stocks, the past three weeks have been among the most profitable stretches in a decade. If you do not, you are watching one of the clearest macro-driven sector rotations of 2026 from the sidelines. The question now is not whether to get in — it is understanding the mechanics well enough to know how long this trade lasts and where the real money is being made.
What Has the Iran Conflict Actually Cost the Pentagon So Far?
Based on open-source tallies of reported strike packages and DoD press briefings through March 19, the US military has expended an estimated $14.3 billion in munitions and operational costs over the first three weeks of active operations. The largest single line item is Tomahawk Land Attack Missiles (TLAMs), manufactured by Raytheon (RTX), with unit costs of approximately $2.1 million each. Strike packages targeting Iranian nuclear infrastructure, air defense nodes, and IRGC command facilities have drawn heavily on TLAM inventories.
Additional expenditures include JDAM precision guidance kits (Boeing, approximately $25,000 per unit but deployed in volume), AIM-120 AMRAAM air-to-air missiles (RTX, ~$1.5M each), and SM-3 Block IIA ballistic missile interceptors (RTX/Boeing joint, ~$27M each) deployed from Arleigh Burke-class destroyers in the Gulf. The SM-3 expenditure alone could account for $2–3 billion given the volume of Iranian ballistic missile salvos intercepted over the Gulf of Oman and Red Sea approaches.
For context, the 2003 Iraq invasion expended roughly $4.7 billion in munitions over the initial 21 days. The Iran conflict is running at more than triple that rate, reflecting both the sophistication of Iranian air defenses and the intensity of the air campaign. See our coverage of the full economic cost of the Iran war for the broader picture.
Which Contractors Are the Direct Beneficiaries?
Lockheed Martin (LMT) — The Broadest Exposure
LMT is the single largest beneficiary by revenue exposure. The F-35 fleet conducting strike missions generates immediate spares and maintenance demand. More significantly, LMT manufactures the JASSM-ER (Joint Air-to-Surface Standoff Missile Extended Range) at approximately $1.3 million per unit — the weapon of choice for deep-penetration strikes against hardened Iranian facilities. JASSM production is currently running at roughly 550 units per year; the DoD will almost certainly request a production surge to 900–1,100 annually. At $1.3M per unit, that is a revenue increase of $450–715 million per year in this product line alone.
LMT’s PAC-3 Patriot interceptor business also accelerates. Israel, Saudi Arabia, UAE, and Qatar have all signaled urgent resupply requests. Each PAC-3 MSE interceptor costs approximately $5.9 million. LMT’s stock has gained roughly 18% since February 28, closing near $620 on March 19. The 12-month consensus price target has moved from $580 to approximately $680 post-conflict.
RTX (Raytheon Technologies) — The Munitions Machine
RTX is the pure-play munitions story. Tomahawk missiles, AIM-120 AMRAAMs, SM-3 interceptors, and the Iron Dome Tamir interceptor (co-produced with Rafael Advanced Defense Systems of Israel) are all RTX products. The company’s Missiles & Defense segment was already its fastest-growing division before the conflict. RTX shares have gained approximately 14% since February 28, with the stock trading near $140.
The Iron Dome resupply angle is material. Each Tamir interceptor costs roughly $50,000–$80,000, and Israel has been firing them at rates exceeding 1,000 per week during peak Iranian drone and rocket salvos. The US government has historically funded Israeli Iron Dome resupply via Foreign Military Financing (FMF) grants — meaning RTX gets paid by the US Treasury regardless of Israeli budget constraints.
Northrop Grumman (NOC) — Stealth and ISR
NOC’s B-21 Raider stealth bomber program — the most classified and highest-margin program in the US arsenal — has almost certainly been accelerated. While operational details remain classified, the company’s Aeronautics Systems segment and its dominance in signals intelligence (SIGINT) platforms make it a key beneficiary of sustained high-tempo operations. NOC is up approximately 16% since late February, trading near $535.
General Dynamics (GD) — Ammunition and Shipbuilding
GD’s Ordnance and Tactical Systems division manufactures artillery shells, small-diameter bombs, and guided rocket systems. The resupply cycle for conventional munitions typically lags air-delivered precision weapons by 60–90 days, meaning GD’s order surge is still building. Its Bath Iron Works shipyard, which builds Arleigh Burke destroyers, has also seen accelerated delivery pressure. GD is up approximately 12% since February 28.
What This Means for US Investors
Defense is now the clearest sector rotation story in the S&P 500. With the broader market under pressure from Fed rate hold uncertainty, rising oil prices, and consumer slowdown, defense stocks offer non-correlated upside driven by government spending rather than consumer demand. The Congressional supplemental package — likely $40–60 billion — is a near-guaranteed earnings catalyst for LMT, RTX, NOC, and GD. The trade has legs through at least mid-2026 based on resupply cycle timelines, but position sizing matters: these stocks are already pricing in significant good news. Consider ITA for diversified exposure rather than single-stock concentration.
The Congressional Supplemental: Why This Is the Real Catalyst
In every modern US military conflict, Congress has passed supplemental appropriations beyond the baseline defense budget to cover operational costs and munitions replenishment. In 2022–2023, Congress passed over $113 billion in Ukraine supplemental packages. For the Iran conflict, defense analysts at Cowen and RBC Capital Markets are modeling a $40–60 billion supplemental within 60–90 days of conflict initiation — likely arriving in May or June 2026.
This matters because supplemental funding goes directly into contractor order books at a speed the normal budget process does not allow. Contracts that would typically take 18 months to negotiate and award get expedited to 60–90 days. For LMT’s JASSM-ER line, RTX’s Tomahawk production (currently ~200 per year), and NOC’s SIGINT platforms, this represents a multi-year revenue acceleration, not just a one-quarter pop.
Also watch for David’s Sling resupply. David’s Sling, co-developed by RTX and Rafael, is Israel’s medium-altitude air defense layer and has been heavily utilized against Iranian ballistic missiles. Each Stunner interceptor costs approximately $1 million. With usage rates in the hundreds per week at peak, this is a significant and sustained revenue stream.

Which ETFs Give You Sector Exposure?
For investors who prefer not to pick individual names, three ETFs offer varying risk/return profiles:
ITA (iShares U.S. Aerospace & Defense ETF) — The most diversified option. Top holdings include LMT (18%), RTX (17%), NOC (12%), GD (8%), and Boeing (8%). AUM approximately $8.2 billion, expense ratio 0.40%. Up approximately 13% since February 28. This is the institutional default for sector exposure.
XAR (SPDR S&P Aerospace & Defense ETF) — Equal-weighted methodology, which gives more exposure to mid-cap names like Curtiss-Wright, Mercury Systems, and Heico. Useful if you want to capture the supply chain surge, not just the prime contractors. Up approximately 11% since February 28.
DFEN (Direxion Daily Aerospace & Defense Bull 3X ETF) — Triple-leveraged, appropriate only for short-term tactical positioning. Up approximately 38% since February 28 but carries significant decay risk in sideways markets. Not a buy-and-hold instrument.
How Long Does the Trade Last?
Defense stock outperformance during conflicts historically follows a predictable pattern: sharp initial surge in weeks 1–4, consolidation in weeks 5–12, then a second leg up when supplemental funding is formally appropriated. The post-9/11 defense rally lasted approximately 18 months before normalizing. The Ukraine-driven rally lasted roughly 24 months for the prime contractors.
The Iran conflict introduces unique variables. If operations remain an air campaign without ground troops, the munitions burn rate stays high but the conflict can end relatively quickly — reducing the multi-year growth narrative. If the conflict expands to include naval blockade operations or ground elements in Iraq/Syria, the timeline extends significantly. Watch for Strait of Hormuz developments as a key escalation indicator.
Base case for institutional positioning: defense outperformance continues through Q3 2026, with the supplemental funding announcement serving as the primary near-term catalyst. Beyond that, the multi-year JASSM-ER and Tomahawk production ramp provides earnings visibility through 2028–2029 regardless of how the conflict resolves.
Frequently Asked Questions
Which single defense stock has the most direct exposure to the Iran conflict munitions burn?
RTX (Raytheon Technologies) has the most direct munitions exposure through Tomahawk cruise missiles, AIM-120 AMRAAMs, SM-3 interceptors, and Iron Dome Tamir co-production. These are the highest-velocity consumables in the current conflict, meaning RTX’s Missiles & Defense segment faces the fastest order replenishment cycle of any prime contractor.
Is it too late to buy defense stocks after a 12–18% move?
Historically, no. In the first Gulf War (1991), Kuwait War (2003), and the Ukraine conflict (2022), the initial surge was followed by a sustained second leg once Congressional supplemental funding was appropriated. With a $40–60 billion package pending and production ramp timelines extending 2–3 years, the fundamental earnings catalyst is not yet fully priced in as of March 2026.
Does a ceasefire immediately reverse defense stock gains?
Not necessarily. Ceasefire announcements historically cause a 5–10% pullback in defense names, but the underlying order books — particularly production ramp contracts for JASSM-ER, Tomahawk, and SM-3 — take 12–24 months to wind down. Supplemental funding already appropriated by Congress cannot be unspent quickly. The longer-term earnings profile remains elevated post-ceasefire.
What is the biggest risk to the defense trade thesis?
A rapid diplomatic resolution before Congressional supplemental funding is passed would reduce both the earnings catalyst and the political momentum for production ramp authorizations. A broader market selloff driven by recession fears could also drag defense names down despite strong fundamentals. Currency risk is minimal since DoD contracts are dollar-denominated.
How do Middle East ETFs relate to the defense story?
They are complementary but distinct. Defense ETFs (ITA, XAR) give US equity exposure to the conflict’s military spending dimension. For the Gulf states’ economic response, see our guide to Middle East ETFs for US investors covering GCC-focused funds.
The bottom line: the Iran conflict has created the most clearly defined defense sector trade since the post-9/11 buildup. LMT and RTX are the highest-conviction names for munitions replenishment. The Congressional supplemental — not the daily headline — is the real catalyst to watch. ITA remains the cleanest vehicle for investors who want sector exposure without single-stock risk.
