Defense stocks surged to all-time highs on Tuesday as the escalating Iran conflict continues to drive unprecedented military spending. Lockheed Martin gained 3.4% to a record close, RTX advanced 4.1%, and Northrop Grumman climbed 2.8%, making the defense sector one of the few bright spots in an otherwise turbulent market.
The rally was fueled by reports that Congress is fast-tracking a $48 billion supplemental defense appropriations bill to fund ongoing operations in the Persian Gulf. The package would cover munitions replenishment, naval operations to secure the Strait of Hormuz, and expanded missile defense deployments across the region.
Order Backlogs Swell
Defense contractors are seeing a generational surge in order backlogs. Lockheed Martin's backlog has grown to over $165 billion, the highest in the company's history, while RTX reported that demand for its Patriot missile defense system has exceeded production capacity through 2028. The conflict has validated years of underinvestment in defense industrial base capacity.
European defense spending has accelerated even more dramatically. NATO members have collectively committed to spending increases that would bring alliance-wide defense budgets above the 2% of GDP threshold for the first time, driven by the realization that the U.S. military cannot simultaneously manage conflicts in the Middle East and deter aggression in other theaters.
Cybersecurity and Space Also Benefit
The conflict has extended beyond kinetic operations into cyber and space domains, benefiting companies across the defense technology ecosystem. CrowdStrike and Palo Alto Networks have seen increased demand for critical infrastructure protection, while satellite communications providers including L3Harris have secured new contracts for resilient military communications.
The iShares U.S. Aerospace and Defense ETF has returned 22% year-to-date, dramatically outperforming the broader market. Analysts project that the structural increase in global defense spending will persist even after the Iran conflict ends, as nations recalibrate their military capabilities for an era of great power competition and regional instability.
