AVAV vs LHX: How AeroVironment and L3Harris Technologies Compare (2026)

AeroVironment (AVAV) is a defense technology company specializing in unmanned and autonomous systems. It is best known for small, man-portable drones used by militaries for reconnaissance and surveillance, and for loitering munitions, notably the Switchblade family, which are precision-strike drones that have drawn significant attention from conflicts and rising global demand. AeroVironment also builds larger unmanned aircraft systems, uncrewed ground robots, and develops autonomy software and counter-drone solutions. Its primary customer is the US Department of Defense, with growing international and allied-government sales. The company has expanded through acquisitions into adjacent areas such as space, loitering munitions, and autonomy. The investment story centers on the structural growth of drones and autonomous systems in modern warfare, where small, attritable, intelligent systems are reshaping how militaries operate. Founded in 1971 and historically associated with pioneering work in efficient flight, AeroVironment is headquartered in Arlington, Virginia, and is a mid-cap defense growth company tied closely to defense budgets and procurement.

L3Harris Technologies is a major US defense and aerospace contractor formed by the 2019 merger of L3 Technologies and Harris Corporation. It positions itself as an agile defense-technology company spanning communications, sensors, electronic warfare, space, intelligence, and missile systems. The business is organized into segments covering Space and Airborne Systems (avionics, sensors, electronic warfare, space payloads), Integrated Mission Systems (ISR, maritime, electro-optical), Communication Systems (tactical radios, secure communications), and, following its acquisition of Aerojet Rocketdyne, a propulsion segment that makes rocket motors and missile propulsion for the US military and space programs. L3Harris primarily sells to the US Department of Defense, allied governments, and intelligence agencies under long-term contracts, which gives it durable, often multi-year revenue backed by defense budgets. It makes money by designing, building, and supporting mission-critical hardware and software, then earning long-tail revenue from sustainment, upgrades, and spare parts. The company also pursues cost-savings programs to expand margins after its large merger and acquisitions. Headquartered in Melbourne, Florida.

Both fit overlapping themes, but they are not interchangeable. AeroVironment is best understood through its own drivers, and L3Harris Technologies through its. The useful comparison is which set of drivers and risks you want exposure to.

• AVAV drivers: Loitering munitions demand; Small unmanned systems franchise.
• LHX drivers: Rising global defense spending; Diversified mission-critical portfolio.

AVAV. AeroVironment trades on a growth multiple that reflects its leadership in fast-growing drone and loitering-munition categories rather than current earnings. The valuation embeds expectations of sustained defense procurement growth and successful expansion into autonomy and space. It is more volatile and richly valued than traditional defense primes, sensitive to order timing and conflict-driven demand swings.

LHX. L3Harris trades at a defense-sector multiple supported by a large multi-year backlog, predictable government revenue, and steady free cash flow. The valuation reflects the durability of defense spending and the company's margin-expansion and capital-return story, offset by debt from acquisitions and program-execution risk. Defense names like L3Harris are often valued on backlog visibility and free cash flow as much as headline earnings.

Headline figures (approximate, early 2026): AVAV shows revenue (ttm) ~$800 million-$1 billion, operating margin ~low-double-digit percent, net income (ttm) Modest; growth reinvested; LHX shows revenue (ttm) ~$21 billion, operating margin ~15%, net income (ttm) ~$1.5-2 billion. A cheaper-looking 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 actually compounding.

Both share a theme, but they suit different temperaments. AeroVironment's case leans on loitering munitions demand, and L3Harris Technologies's on rising global defense spending. 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: AeroVironment depends heavily on US defense procurement, so budget cycles, appropriations timing, and program decisions cause lumpy, hard-to-predict revenue and order flow. For LHX, l3Harris depends heavily on US government and allied defense budgets, so spending cuts, continuing resolutions, government shutdowns, or shifting priorities directly threaten revenue.

Pick AVAV if you believe its drivers more; LHX 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 AVAV and LHX guides.

AVAV and LHX 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 AVAV and LHX exposure against your real portfolio. It is not an investment adviser.
