Top Best Defense Stock Every Value Investor Should Know
The best defense stock is not simply the one with the highest recent return. It is the company that converts a large and growing government revenue stream into consistent free cash flow, maintains a manageable debt load, and trades at a price that leaves room for a real return on your capital. As of early 2026, a handful of U.S. and European contractors meet that bar. This post shows you exactly which ones, and the numbers behind each pick.
Defense spending is structural in a way most sectors are not. NATO countries committed to 2% of GDP in defense expenditure, the U.S. defense budget reached $886 billion for fiscal year 2025, and bipartisan support for continued military modernization remains intact. That spending does not fluctuate with consumer confidence or interest rate cycles the way retail or real estate does.
Key Takeaways
- The best defense stock candidates share three traits: long-cycle government contracts, high barriers to entry, and free cash flow conversion above 80%.
- Lockheed Martin (LMT) trades at a forward P/E near 17, below its 5-year average of 19.4, with an EV/Revenue around 2.0.
- RTX Corporation (RTX) offers the broadest exposure across defense electronics, engines, and missiles, with a debt-to-equity ratio that has improved from 0.9 to 0.7 since the 2020 Raytheon merger.
- Northrop Grumman (NOC) is the most concentrated pure-play on next-generation nuclear and space systems, with a P/S ratio near 1.6.
- European names such as Rheinmetall (RHM) and BAE Systems (BA.L) have re-rated sharply since 2022 but still offer lower valuations than U.S. peers on an EV/EBITDA basis.
- A disciplined value screen using our screener narrows the full defense universe to 8-12 names that meet combined quality and price criteria.
Why Defense Is a Structurally Different Sector
Defense contractors do not sell to millions of consumers. They sell to governments on contracts that can span 10 to 30 years. The F-35 program, Lockheed's flagship, has a total lifecycle value estimated above $1.7 trillion including sustainment. No consumer business works on that timeline.
The consequence for investors is that revenue visibility is unusually high. Backlog figures replace same-store-sales or monthly bookings as the primary forward indicator. Lockheed reported a backlog above $165 billion at the end of 2024. RTX's backlog exceeded $200 billion. These numbers represent years of contracted work, not aspirational guidance.
The flip side: defense stocks rarely produce rapid growth. Margins are regulated, cost overruns can become political, and the customer base is concentrated in a handful of governments. You own defense for quality and cash flow, not for exponential revenue expansion.
The Fundamental Screen: What Makes a Best Defense Stock
Before picking names, define what "best" means in measurable terms. We screened the sector on five criteria.
| Metric | Minimum Threshold | Rationale |
|---|---|---|
| Free Cash Flow Conversion | Above 80% of net income | Confirms earnings quality |
| Debt-to-Equity | Below 1.5 | Controls balance sheet risk |
| EV/Revenue | Below 3.0 | Prevents overpaying for revenue |
| Operating Margin | Above 10% | Defense programs must be profitable |
| Backlog-to-Revenue | Above 3.0x | Revenue visibility for 3+ years |
Companies passing all five filters as of Q1 2026: Lockheed Martin, RTX Corporation, Northrop Grumman, L3Harris Technologies, and Leidos Holdings. General Dynamics passes four of five (EV/Revenue is 1.8, well inside the threshold, but backlog-to-revenue sits near 2.8x). Boeing (BA) fails on debt-to-equity, which remains above 3.0 due to the 737 MAX program aftermath.
Lockheed Martin: The Benchmark Name
Lockheed Martin (LMT) is the largest pure-play defense contractor by revenue, generating approximately $67 billion in sales in fiscal 2024. The F-35 alone accounts for about 27% of that. Sikorsky helicopters, PAC-3 missiles, and classified space systems fill the rest.
The valuation case rests on three facts. First, LMT's forward P/E near 17 sits at a discount to the S&P 500 at roughly 21. Second, free cash flow per share has compounded at about 8% annually over the past decade. Third, the company has repurchased more than 30% of its shares outstanding since 2015, which mechanically lifts per-share metrics even without underlying growth.
The risk: the F-35 is so dominant in Lockheed's revenue mix that any program delay, cost ceiling dispute with the Pentagon, or export restriction creates outsized revenue uncertainty. LMT is not diversified in the way RTX is.
RTX Corporation: Breadth Across the Defense Chain
RTX (formerly Raytheon Technologies) builds Pratt & Whitney jet engines for both commercial and military aircraft, alongside Raytheon's missile systems, radar, and electronic warfare products. The commercial aviation exposure through Pratt & Whitney adds a second growth engine that pure defense contractors lack.
| Segment | 2024 Revenue | Operating Margin | Backlog |
|---|---|---|---|
| Collins Aerospace | $26.4B | 15.8% | $21B |
| Pratt & Whitney | $23.2B | 10.2% | $83B |
| Raytheon | $25.1B | 11.4% | $52B |
| Total | $74.7B | 12.4% | $156B |
The debt-to-equity ratio of 0.7 is the cleanest it has been since the merger. Forward P/E sits near 20.5, a modest premium to Lockheed that reflects the commercial aviation diversification. For investors who want defense exposure without betting entirely on government budgets, RTX is the most balanced option in the sector.
Northrop Grumman: The Space and Nuclear Bet
Northrop Grumman (NOC) occupies a narrower but strategically significant niche: nuclear modernization (B-21 Raider bomber, Sentinel ICBM replacement), space systems (James Webb Space Telescope, classified intelligence satellites), and cyber warfare platforms.
The B-21 program alone is projected to deliver 100+ bombers at a unit cost above $550 million each, totaling over $55 billion in potential contract value. Northrop is the only prime contractor on that program.
The valuation is not cheap by absolute standards: P/S near 1.6, forward P/E near 19.5. But the concentration of revenue in long-lifecycle nuclear and space programs means the backlog quality is arguably the highest in the sector. Once a government commits to nuclear modernization, contract cancellation is extraordinarily rare.
L3Harris and Leidos: The Overlooked Names
L3Harris Technologies (LHX) focuses on electronic warfare, communications, and intelligence systems. Revenue is roughly $22 billion, P/E near 16.8, and free cash flow yield above 5.5%. For value-oriented investors, L3Harris screens as the most attractive combination of price and quality metrics in the mid-cap defense space.
Leidos Holdings (LDOS) is primarily a services and IT contractor, which limits the hardware backlog but creates extremely sticky government IT relationships. Leidos holds classified data management and intelligence contracts for agencies including the NSA and DHS. Revenue near $15 billion, operating margin around 9.5%, and a P/E under 16 make it the cheapest name in the group on a headline earnings basis.
Both names appear in the top quartile of our screener results when filtering for defense sector stocks with EV/Revenue below 2.5 and free cash flow yield above 4.5%.
How to Size a Position in Defense Stocks
Defense stocks tend to cluster in correlation during broad market selloffs. Buying five names in the sector does not provide as much diversification as buying five names across different sectors. A reasonable approach: one or two U.S. prime contractors (LMT or RTX as the anchor), one mid-tier name (L3Harris or Leidos for value), and optionally one European name for geographic diversification.
The VMCI Score framework assigns 35% weight to Value, 30% to Quality, 15% to Integrity, 12% to Growth, and 8% to Risk. Defense names typically score highest on Quality (predictable cash flows, durable margins) and lowest on Growth (limited above-GDP revenue expansion). A composite score above 70 across those pillars indicates a name worth holding at current prices.

Frequently Asked Questions
what happens if the stock market crashes
Defense stocks historically hold up better than the broad market during crashes because revenue is tied to government contracts rather than consumer spending. During the 2020 COVID crash, the S&P 500 fell 34% peak-to-trough while Lockheed Martin fell about 20%. Government budgets do not disappear in recessions, which gives defense stocks a partial cushion. That said, no sector is immune, and overvalued defense names can still drop significantly.
what time does the stock market open
The U.S. stock market opens at 9:30 a.m. Eastern Time on weekdays, excluding federal holidays. Pre-market trading begins at 4:00 a.m. Eastern through most major brokerages, and after-hours trading runs until 8:00 p.m. Eastern. Defense stocks like LMT and RTX often see significant price moves during earnings releases, which typically happen before or after regular trading hours.
are stock markets closed today
U.S. stock markets observe 11 federal holidays per year, including New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving, and Christmas. You can verify current trading status on the NYSE or Nasdaq websites, or by checking whether your brokerage account shows live quotes.
what time does the stock market close
The U.S. stock market closes at 4:00 p.m. Eastern Time on regular trading days. After-hours trading continues until 8:00 p.m. Eastern on most platforms. Defense stocks frequently release earnings after the 4:00 p.m. close, meaning the stock can re-price significantly before the next regular session opens.
when does the stock market open
The U.S. stock market opens for regular trading at 9:30 a.m. Eastern Time, Monday through Friday, excluding federal holidays. If you are trading defense stocks or ETFs like ITA or XAR from a non-U.S. time zone, calculate the opening time against Eastern Time: London is 5 hours ahead, Frankfurt 6 hours, Tokyo 14 hours ahead.
why is the stock market down today
Stock markets fall for many reasons: inflation data, Federal Reserve rate signals, earnings disappointments, geopolitical events, or sector-specific news. Defense stocks can fall even when their own fundamentals are sound if broader risk-off sentiment pulls down the entire market. Distinguish between price drops driven by valuation re-rating (the whole market getting cheaper) and drops driven by actual fundamental deterioration in the specific company you own.
