Best Defense Stocks to Buy in 2026: Full Analysis

Lockheed Martin is the world’s largest defense company and the default anchor position for any institutional defense portfolio. Its $194 billion backlog — representing more than 2.5 years of annual revenue — provides extraordinary revenue visibility that few companies in any sector can match. The F-35 Lightning II program alone accounts for approximately 25% of total revenue, with over 3,000 jets on order across 17 nations. The company’s framework agreements to triple PAC-3 MSE interceptor production (from 600 to 2,000 annually) and quadruple THAAD production (to 400 units per year) directly capture the NATO spending surge in missile defense systems.

The analyst consensus is Hold rather than Buy — not because the business is weak, but because the stock has already run hard. LMT is up significantly since 2024, trading near all-time highs around $676-692. The 2026 guidance for $77.5-80 billion in revenue and EPS of $29.35-30.25 is solid, but valuation leaves limited room for multiple expansion. Susquehanna raised its price target to $740 in March 2026, but the consensus sits at $623 — implying modest downside from current levels. For long-term investors, LMT is a core holding; for new buyers at current prices, the entry point requires patience.

RTX Corporation is the most diversified name in traditional defense — combining Raytheon’s missile and missile defense systems with Pratt & Whitney’s jet engine business and Collins Aerospace’s avionics and systems. This diversification is both a strength and a valuation anchor. The commercial aviation side (Pratt & Whitney) has been in a multi-year upcycle as airlines replace aging fleets, providing earnings stability independent of defense budget cycles. The Raytheon segment directly benefits from the global depletion of missile stockpiles — the Pentagon has expended significant inventory supporting Ukraine, creating a sustained replenishment demand that flows directly to RTX’s production lines.

The European angle is particularly important for RTX in 2026. As NATO members accelerate procurement, Raytheon’s Patriot missile systems, Stinger missiles, and advanced radar systems are among the most demanded platforms. Jefferies raised its price target to $155 from $130 in recent coverage, citing margin improvement potential at Pratt & Whitney and incremental budget capture in European defense. The stock has already rallied 26% YTD, and the average target of $140 implies modest downside — but the 2027 FCF target of $10 billion, if achieved, would support a meaningful re-rating.

Northrop Grumman occupies a unique position in the defense landscape — it is the only company that can build nuclear-capable stealth bombers at scale. The B-21 Raider program, the US Air Force’s next-generation strategic bomber, is a Northrop exclusive that directly ties the company’s revenue to America’s nuclear deterrence posture. That is not a contract that gets cancelled. Beyond the B-21, NOC’s portfolio spans space systems ($11.7B revenue), missile defense, and mission-critical electronics for intelligence and surveillance platforms. The nuclear triad connection — missiles, submarines, bombers — makes Northrop the most “untouchable” of the traditional primes from a budget-cut perspective.

The analyst consensus of Moderate Buy with a $541 target (9.4% upside from ~$495) makes NOC the most attractive pure valuation entry among the traditional primes right now. UBS analyst Gavin Parsons maintains a Buy rating, citing the record backlog as a longer-term growth driver. The near-term Q1 2025 execution miss has created a more attractive entry point than LMT or RTX, both of which have already priced in much of the NATO spending narrative. For investors who want defense exposure with the most policy-insulated revenue base available, NOC is the strongest case.

General Dynamics is the most diversified of the traditional defense primes, combining two primary military shipbuilding programs (Virginia-class submarines, Arleigh Burke destroyers), land systems (Abrams tanks, Stryker vehicles), and one of the largest defense-focused IT services businesses through GDIT. The submarine program is a particular standout — Virginia-class submarine production is running at capacity, with demand from both the US Navy and the AUKUS program (Australia’s nuclear submarine deal) extending the production runway well into the 2030s. Submarines are one of the most difficult platforms to accelerate production on — the supply chain constraints create a durable competitive moat.

The GDIT (General Dynamics Information Technology) segment provides revenue stability when hardware cycles slow, servicing classified IT infrastructure for DoD and intelligence agencies. This is also the segment most at risk from the DOGE-driven government efficiency push — but the classified nature of much of GDIT’s work insulates it from the cuts targeting more visible civilian programs. GD’s 2.2% dividend yield is the highest among the large-cap primes, and the buy consensus reflects the combination of strong backlog visibility and reasonable valuation relative to peers.

Palantir is the most important defense stock that most defense investors don’t own. The company’s Artificial Intelligence Platform (AIP) has become mission-critical infrastructure for the US military and intelligence community — processing, synthesizing, and modeling operational data in real time to support battlefield decision-making. The Golden Dome software contract, shared with Anduril, is the validation event that converts PLTR from an “interesting AI company with government contracts” into “the software layer of America’s strategic defense architecture.” That is a fundamentally different investment thesis.

The US Army’s $20 billion Anduril contract, which Palantir is supporting from the software intelligence side, and the broader push toward AI-enabled autonomous systems across all service branches, means Palantir’s addressable defense market is expanding rapidly. The company’s commercial AI platform (AIP for Enterprise) is also growing — providing a hedge against defense budget volatility. At approximately $90 per share, PLTR trades at a significant premium to its traditional defense peers — there is no backlog metric or dividend yield to anchor valuation. The investment case is pure growth: a platform that is becoming the operating system of the AI-enabled military, at the beginning of a decade-long procurement transition.
