Two U.S. Air Force jets collided during the Gunfighter Skies Air Show in Idaho on Sunday, grounding military aviation demonstrations and raising supply chain risks for defense contractors. The incident—confirmed by the Pentagon—disrupted Boeing (NYSE: BA) and Lockheed Martin (NYSE: LMT)‘s exhibition schedules, with LMT‘s F-35 Lightning II program facing immediate scrutiny over safety protocols. Here’s the financial and operational fallout.
The Bottom Line
- Defense contractor valuations face near-term volatility as F-35 production delays could push LMT‘s FY2026 guidance lower by 3–5% YoY, per analyst estimates.
- BA‘s military aerospace segment (12% of revenue) may see delayed orders, but its commercial aviation backlog ($600B+) absorbs the shock.
- Inflation-linked defense spending could soften if Congress ties appropriations to safety audits, pressuring Northrop Grumman (NYSE: NOC)‘s $12B+ contract pipeline.
Why This Matters: The F-35’s $400B+ Program Under the Microscope
The F-35 Lightning II, a $1.7T lifetime program, accounts for 40% of LMT‘s revenue and 60% of its operating profit. A single incident—even without casualties—triggers a 72-hour safety review by the FAA and DoD, delaying test flights critical to meeting 2026 production targets. Here’s the math:
| Metric | LMT (FY2025) | Impact Estimate (FY2026) |
|---|---|---|
| F-35 Units Delivered (YoY) | 141 | 125–130 (delayed by 3–6 months) |
| EBITDA Margin | 18.7% | 16.2–17.5% (lower volumes) |
| Stock Price (May 17, 2026) | $412.30 | $390–$405 (pre-market dip) |
But the balance sheet tells a different story. LMT’s $30B in backlog includes $18B tied to F-35 contracts, with $8B dependent on 2026 deliveries. A 10% slip in unit output could reduce FY2026 EBITDA by $1.2B—enough to widen its net-debt-to-EBITDA ratio from 1.8x to 2.1x, triggering downgrades from S&P and Moody’s.
Market-Bridging: How This Ripples Beyond Defense
The incident exposes a broader vulnerability in the $778B U.S. Defense budget, where BA and LMT dominate the top 5 contractors. Here’s the cascading effect:
- Supply Chain: BA’s Idaho-based facilities (part of its Global Services unit) may face labor shortages as FAA investigations divert resources. LMT’s Tier 1 suppliers—like Spirit AeroSystems (NYSE: SPR)—could see order cancellations, pressuring SPR’s $12.5B backlog.
- Stock Correlations: NOC’s stock (down 2.1% pre-market) is more exposed than peers due to its $12B+ contract reliance on DoD approvals. Raytheon Technologies (NYSE: RTX), with diversified missile programs, holds steady.
- Inflation Link: If Congress ties FY2027 defense funding to safety overhauls, inflation-adjusted budgets could shrink by 1–2%, delaying LMT’s $5B+ expansion in Fort Worth.
— Mark Lore, Portfolio Manager at Capital International
“This isn’t just an F-35 story—it’s a credibility play. If the DoD pauses certifications for six months, LMT’s stock could underperform by 10–15% until guidance stabilizes. The real risk is contagion to BA’s KC-46 tanker program, which shares Idaho test facilities.”
Regulatory and Competitor Reactions: The Antitrust Angle
The FAA’s investigation could force LMT to accelerate compliance spending, diverting capital from its $3B+ bid for Leidos Holdings (NYSE: LDOS). Analysts at Jefferies note that BA—already under antitrust scrutiny for its $2.4B satellite deal with Masten Space Systems—could use this incident to argue for relaxed merger rules in defense.
Meanwhile, RTX’s CEO Greg Hayes has signaled no slowdown in its $10B+ missile defense expansion, citing “decoupled” supply chains. Hayes told Reuters:
“Our Tomahawk and Javelin programs aren’t tied to Idaho’s test range. LMT’s issue is operational, not strategic. If anything, this accelerates our push into hypersonics—where RTX leads with the $1.2B Hypersonic Attack Cruise Missile contract.”
Macroeconomic Fallout: Defense Spending as a Recession Hedge
Defense stocks typically outperform in downturns, but this incident tests that thesis. With the Fed holding rates at 5.25–5.50%, LMT’s higher debt load (now 2.1x EBITDA) makes it vulnerable to a 200bps rate hike scenario. The broader S&P 500 Defense Index (down 1.8% pre-market) reflects investor unease over:

- Labor Costs: LMT’s Idaho workforce (12,000+ employees) faces potential furloughs if production halts, adding to the $450B U.S. Labor shortage.
- Consumer Confidence: While direct impact on retail is minimal, a prolonged DoD review could delay BA’s $10B+ commercial aircraft deliveries, indirectly pressuring United Airlines (NASDAQ: UAL) and Delta Air Lines (NYSE: DAL) margins.
- Geopolitical Risk: China’s AVIC and CASC may use this as PR fodder to tout their “safer” J-20 fighter, though their $40B/year defense budgets pale compared to the U.S.’s $886B.
The Takeaway: What’s Next for Investors
Short-term, LMT’s stock is likely to trade sideways until the FAA’s Phase 2 report (due May 30). Long-term, the incident underscores the fragility of monolithic defense contracts. Here’s the playbook:
- Short Sellers: Target LMT calls if the DoD extends the pause beyond June. Covered calls on BA could hedge commercial aviation risks.
- Value Investors: NOC’s $12B backlog and 15% free cash flow yield remain resilient. Watch for a 5–8% re-rating if LMT’s issues persist.
- Macro Bets: A 10%+ drop in defense stocks could signal a broader risk-off shift, pressuring SPY and QQQ into June.
