Defense giants are emerging as relative winners from the Iran war and the oil shock roiling global markets, with investors flocking to the largest U.S. primes as hedges against escalating conflict and inflation risk.

Crude prices surged past $110 a barrel, before pulling back on Monday as fighting and disruption around the vital Strait of Hormuz chokes off a key artery for global energy flows, triggering the biggest weekly gain in U.S. oil futures on record and stoking fears of renewed inflation.

While major equity indexes have slumped on the prospect of higher-for-longer interest rates, shares of defense contractors have jumped on expectations of heavier weapons usage a nd larger Pentagon budgets tied to the conflict.

The Majors

Lockheed Martin Corp. (LMT  ) has been the sector standout, with the stock up nearly 40% this year, according to Benzinga Pro data, and setting fresh all-time highs as Iran headlines hit.

The maker of the F‑35 fighter jet, precision-guided munitions and air and missile defense systems is riding a record backlog near $200 billion and a ramp in free cash flow, giving the war-driven rally an earnings backbone rather than pure speculation.

RTX Corp. (RTX  ), parent of Raytheon, has logged single-day gains of 4% to 6% on key news days as investors bet on surging demand for Patriot and THAAD missile interceptors and F‑35 engines after waves of drones and missiles over Iran and the Gulf.

Northrop Grumman Corp. (NOC  ) has also rallied more than 8% over the past month, buoyed by its role in strategic bombers, missile defense and intelligence, surveillance and reconnaissance platforms central to any sustained Iran campaign.

General Dynamics Corp. (GD  ) and L3Harris Technologies, Inc. (LHX  ) are participating in the move, grinding toward 52-week highs as investors seek exposure to submarines, surface ships, land systems, communications and sensor networks likely to benefit from structurally higher defense spending.

Their advance has been steadier and less headline-sensitive than the missile and airframe specialists, reflecting lower beta, but also more valuation restraint after a strong run.

Looking Ahead

The policy backdrop has added fuel to the rally. President Donald Trump met with defense executives last week and floated a substantial supplemental request to boost munitions production, signaling that Washington expects a prolonged draw on stockpiles if the Iran war drags on.

Caution is warranted as a sudden ceasefire or a broader risk-off wave driven by oil and growth fears could knock multiples back, even for these relative safe havens.
