LMT vs NOC: How Lockheed Martin and Northrop Grumman Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. LMT and NOC share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined LMT and NOC exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Lockheed Martin is the largest defense contractor in the world, generating the vast majority of its revenue from the US government and allied militaries. It is organized into four segments: Aeronautics (home of the F-35 Lightning II, F-22, and C-130, the largest segment), Rotary and Mission Systems (Sikorsky helicopters, combat systems, radar, and sensors), Missiles and Fire Control (precision missiles, HIMARS, PAC-3 interceptors, and hypersonics), and Space (satellites, missile-defense systems, and strategic and hypersonic programs). Lockheed designs, builds, and sustains some of the most advanced and mission-critical weapons systems in the world, including the F-35, its single largest program, which generates long-tail revenue from production, upgrades, and decades of sustainment. The company makes money under long-term government contracts, with a large multi-year backlog that provides revenue visibility. It pursues hypersonics, missile defense, and space as growth areas. As a flagship defense name, Lockheed is a steady cash generator that returns substantial capital to shareholders. Headquartered in Bethesda, Maryland.

Northrop Grumman is one of the largest US defense contractors, supplying advanced aerospace, defense, and security systems primarily to the US government and allied militaries. Its business is organized around four segments: Aeronautics Systems (military aircraft and the B-21 Raider stealth bomber), Space Systems (satellites, launch, and missile-defense and space sensors), Mission Systems (radars, electronic warfare, sensors, and networking), and Defense Systems (missiles, ammunition, and the ground-based strategic deterrent program modernizing US intercontinental ballistic missiles). Northrop is a leader in stealth aircraft, space systems, and strategic deterrence, holding key positions on programs that are central to long-term US defense priorities. Revenue is dominated by long-duration government contracts, providing visibility and a large multi-year backlog, though margins depend on program execution and the mix of fixed-price versus cost-plus work. As a prime contractor on strategic programs like the B-21 bomber and the Sentinel ICBM, Northrop is tied to defense-budget trends and great-power competition. Founded in 1939 (modern form from the 1994 Northrop-Grumman merger) and headquartered in Virginia, it is a large-cap defense and aerospace company that pays a growing dividend.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• LMT drivers: The F-35 franchise; Rising defense budgets and munitions demand.
• NOC drivers: Strategic franchise programs; Large backlog and revenue visibility.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Lockheed depends overwhelmingly on US and allied defense budgets, so spending cuts, continuing resolutions, shutdowns, or shifting priorities directly threaten revenue. For NOC, northrop depends heavily on the US government, so defense-budget cuts, continuing resolutions, or shifting priorities directly affect revenue.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick LMT if you believe its drivers more; NOC if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the LMT and NOC guides.

LMT. Lockheed trades at a defense-sector multiple supported by an enormous backlog, predictable government revenue, and reliable free cash flow that funds a growing dividend and large buybacks. The valuation reflects the durability of defense spending and the F-35 annuity, offset by program-concentration risk and occasional charges on fixed-price contracts. As a defensive cash compounder, Lockheed is often valued on free cash flow and backlog visibility as much as headline earnings.

NOC. Northrop trades at a valuation in line with large defense primes, reflecting backlog visibility, strategic-program leadership, and steady cash generation balanced against program-execution and budget risk. The multiple tends to expand during periods of rising defense budgets and geopolitical tension and compress when budget concerns or program charges weigh on sentiment. The dividend and buybacks support total return.

Headline figures (approximate, early 2026): LMT shows revenue (ttm) ~$72 billion, operating margin ~11-12%, net income (ttm) ~$5-6 billion, p/e (ttm) ~17x; NOC shows revenue (ttm) ~$42 billion, operating margin ~10-11% (sensitive to program mix and charges), net income (ttm) ~$3.5-4 billion, eps (ttm) ~$25.

LMT and NOC are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
