GD vs HII: Which Is the Better Buy in 2026?

Last updated September 2026

Short answer

GD is the larger of the two ($99.95B market cap): the incumbent the market prices for continued execution (19.92x forward earnings, beta 0.33). HII is the smaller challenger ($11.52B), cheaper on forward earnings (14.04x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.

GD vs HII: the tie-breaker metrics

Same yardstick, side by side (as of September 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.

MetricGDHIIWhat it tells you
Market cap$99.95B$11.52BSize. The larger name is the incumbent; the smaller has more room to grow and more to prove.
Forward P/E19.9214.04Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up.
Trailing P/E22.5317.43Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price.
Beta0.330.24Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through.
Price vs 52-week range67% of range15% of rangeWhere today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why.
Price / book3.722.17How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price.

Reading it: HII is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

Before you buy: how GD and HII affect your concentration

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. GD and HII 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 GD and HII 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.

What does General Dynamics (GD) do?

General Dynamics is one of the largest US aerospace and defense contractors, with a diversified portfolio spanning four main areas. Its Aerospace segment builds Gulfstream business jets, among the most prestigious in the world. Marine Systems builds nuclear-powered submarines and other naval vessels for the US Navy, including ballistic missile and attack submarines through its Electric Boat and Bath Iron Works yards. Combat Systems produces armored vehicles, including the Abrams tank and Stryker, plus munitions and weapons systems. Technologies provides IT services, communications, and mission systems to defense and government customers. General Dynamics makes money through long-term government contracts for shipbuilding, vehicles, and services, plus commercial Gulfstream jet sales. Headquartered in Reston, Virginia, the company benefits from large multi-year defense programs, a substantial backlog, and steady government demand. Its mix of defense and high-end business aviation gives it a balance of stable contracted revenue and cyclical premium jet sales.

What does Huntington Ingalls (HII) do?

Huntington Ingalls Industries is the largest military shipbuilder in the United States. It designs, builds, and maintains the most complex naval vessels in the US fleet, including nuclear-powered aircraft carriers, nuclear submarines, amphibious assault ships, and surface combatants. The company operates two principal shipyards: Newport News Shipbuilding in Virginia, which is the only US builder of nuclear aircraft carriers and one of two builders of nuclear submarines, and Ingalls Shipbuilding in Mississippi, which builds amphibious and surface ships. A third segment, Mission Technologies, provides defense and federal technology services including unmanned systems, cyber, and intelligence support. HII makes money almost entirely from the US Navy and government through long-cycle contracts that span years or decades, giving it deep visibility into future revenue via a large backlog. Spun off from Northrop Grumman in 2011 and headquartered in Newport News, Virginia, HII occupies a near-monopoly position in critical naval shipbuilding.

GD vs HII: how do they differ?

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

  • GD drivers: Submarine and naval programs; Gulfstream business jets.
  • HII drivers: Irreplaceable shipyards; Long backlog and submarine demand.

Which fits which kind of investor

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: General Dynamics depends heavily on US government defense spending, which is subject to budget politics, continuing resolutions, and shifting priorities. For HII, hII depends almost entirely on the US government, so budget delays, continuing resolutions, or shifts in defense priorities directly affect it.

GD or HII: which should you pick?

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 GD if you believe its drivers more; HII 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 GD and HII guides.

GD vs HII: the full fundamentals

GD. General Dynamics is valued as a stable, cash-generative defense prime with a large multi-year backlog plus a cyclical premium business jet franchise. Investors weigh the predictability of government contracts and a long dividend-growth record against the cyclicality of Gulfstream and execution risk in shipbuilding. The valuation reflects steady defense demand and consistent capital return.

HII. HII trades at a moderate valuation relative to broad defense peers, reflecting thinner shipbuilding margins, capital intensity, and a history of program cost pressure, balanced against an essentially irreplaceable strategic position and a large multi-year backlog. The market tends to value the durability and backlog visibility while discounting for execution and margin risk inherent in complex naval construction.

Headline figures (approximate, early 2026): GD shows revenue (ttm) ~$45 to 50 billion, operating margin ~low double digits percent, net income (ttm) ~$3.5 to 4 billion, order backlog ~$90 billion or more; HII shows revenue (ttm) ~$12 billion, operating margin ~7%, net income (ttm) ~$550 million, p/e (ttm) ~17x.

The bottom line: GD vs HII

GD and HII 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. Walnut can show your combined GD and HII exposure against your real portfolio. It is not an investment adviser.

FAQ

What is the difference between GD and HII?

+

General Dynamics is one of the largest US aerospace and defense contractors, with a diversified portfolio spanning four main areas. Huntington Ingalls Industries is the largest military shipbuilder in the United States. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.

Is GD or HII the better stock?

+

Neither is universally better. GD is the larger incumbent; HII is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.

Which is cheaper, GD or HII?

+

On forward P/E (as of September 2026), GD trades at 19.92x and HII at 14.04x, so HII is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.

Should you own both GD and HII?

+

Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.

What are the risks of GD vs HII?

+

GD: General Dynamics depends heavily on US government defense spending, which is subject to budget politics, continuing resolutions, and shifting priorities. Large shipbuilding and vehicle programs carry execution risk, including labor shortages, supply chain constraints, and cost overruns on fixed-price contracts. The Gulfstream business is cyclical and sensitive to economic conditions and high-end demand. Program delays, new-aircraft certification timing, and competition in business jets can affect results. Defense procurement is competitive, and losing a major program would be material. Margins can be pressured by inflation and labor costs in shipbuilding. As with all defense contractors, political and policy shifts add uncertainty to long-term planning. HII: HII depends almost entirely on the US government, so budget delays, continuing resolutions, or shifts in defense priorities directly affect it. Shipbuilding is enormously complex, and the company has faced cost overruns, schedule slips, and inflation in labor and materials that can pressure margins on fixed-price work. Skilled-labor shortages and supply chain constraints in the defense industrial base are persistent challenges. The business is capital intensive with long cash conversion cycles. Concentration in a few massive programs means problems on any one ship can be financially significant, and free cash flow has at times been volatile.
