General Dynamics (NYSE:GD | GD Price Prediction) and Lockheed Martin (NYSE:LMT) both reported Q1 2026 earnings, and the results frame a naval showdown. GD’s Marine Systems delivered 21.0% revenue growth on submarines and destroyers. Lockheed answered with a $3.45 billion acquisition of Ultra Maritime, betting on sonobuoys and anti-submarine sensors rather than hulls.

Submarines Carry GD. Program Charges Bruise Lockheed.

GD posted $13.48 billion in revenue, up 10.3% year over year, with diluted EPS of $4.10, a fourth straight beat. Marine Systems operating earnings jumped 26.4%, reflecting Electric Boat and Bath Iron Works pulling ahead on Columbia and Virginia-class submarine work. Free cash flow reached $1.952 billion. CEO Phebe Novakovic called it “a very good start to the year, delivering strong operating results and excellent cash conversion.”

Lockheed’s quarter looked different. Revenue landed at $18.021 billion, essentially flat, and diluted EPS of $6.44 came in missing expectations of $6.70. A $125 million F-16 charge, plus pressure on C-130, CH-53K, and Seahawk, compressed segment margins to 10.1% from 11.6%. Operating cash flow collapsed to $220 million, and free cash flow flipped to negative $291 million.

Hulls vs. Sensors: Two Naval Playbooks

Lens	General Dynamics	Lockheed Martin
Naval bet	Submarine and destroyer hulls	Ultra Maritime ASW payloads
Q1 FCF	$1.952B	-$291M
Book/backlog	$188.44B contract value	$194B backlog
Forward P/E	23x	18x

GD owns the physical monopoly on Navy nuclear boats. Lockheed is trying to weaponize Ultra’s sonobuoy and acoustic decoy tech to occupy the software and payload layers riding on GD-built platforms. CEO Jim Taiclet is also scaling munitions, signing framework agreements he says will lift Patriot, THAAD, and PrSM output by 3 to 4 times current rates.

The Next Test Is Whether Lockheed Can Absorb Ultra Cleanly

I will be watching whether Lockheed’s Rotary and Mission Systems segment, already down 8% this quarter, can integrate a capital-heavy maritime pipeline without further margin dilution. For GD, the catalyst is capacity: whether Marine Systems can keep converting Columbia and Virginia-class demand into cash at current rates. Aerospace orders of $3.8 billion, up 63%, add a Gulfstream cushion Lockheed simply does not have.

Why I Lean Toward General Dynamics Right Now

For steadier compounding tied to structural monopolies, GD screens as the cleaner setup. Trading around $374 with a 23x forward P/E and eight coordinated director purchases at $359.85 in June, the shipbuilder looks like the cleaner story. Lockheed, at 18x forward earnings with a $617 analyst target, fits investors comfortable underwriting a turnaround on fixed-price program execution. The Ultra integration and F-16 charges are the key overhangs to monitor on LMT before the setup clarifies.
