Snapshot

Autonomous military systems — drones, loitering munitions (small guided weapons that circle a target area until deployed), uncrewed combat aircraft, and autonomous ground/sea vehicles — are the fastest-growing hardware category in US defense. The Pentagon's FY2026 budget dedicates $9.4 billion to unmanned aerial vehicles alone, part of a $13.4 billion autonomy line item that exists for the first time as a standalone budget category. The Defense Autonomous Warfare Group (DAWG) replaces the Replicator initiative with an FY2027 request of $54.6 billion. The four tracked public companies — KTOS, AVAV, LHX, NOC — range from pure-play drone makers to diversified primes where autonomous systems are a growing but minority segment.

KTOS and AVAV are sub-$12B market cap pure-plays absorbing initial production contracts; LHX ($57B) and NOC ($76B) capture autonomous demand through ISR sensors, IBCS missile-defense integration, and classified programs. The four companies' combined backlog exceeds $137 billion, though only a fraction is autonomous-specific.

The product & how money is made

• Attritable combat drones — low-cost uncrewed aircraft designed to be expendable. Kratos's XQ-58A Valkyrie targets a per-unit cost far below manned fighters, flying autonomously alongside F-35s or F/A-18s. Revenue comes from development contracts (cost-plus-fixed-fee) transitioning to production contracts (fixed-price). Kratos's Unmanned Systems (KUS) segment did $292M in FY2025 revenue at 6.2% adj. EBITDA margin (still in development/low-rate production).
• Tactical drones and loitering munitions — small, portable systems for infantry and special operations. AeroVironment's Switchblade 300/600 are combat-proven in Ukraine. Revenue is product sales plus services. AVAV's Autonomous Systems segment did $285M in Q1 FY2026 alone (annualizing above $1B), with 18.5% segment adj. EBITDA margin.
• ISR and sensor payloads — L3Harris builds sensors, electronic warfare suites, and communications links that go on autonomous platforms. Revenue is mostly fixed-price production contracts with 15-16% segment operating margins. LHX's full company did $22.5B TTM revenue at 15.7% adj. segment operating margin.
• Autonomous integration and battle management — Northrop Grumman's IBCS (Integrated Battle Command System) connects autonomous sensors to shooters across all domains. NOC also builds Triton maritime surveillance drones and the B-21 (autonomous-capable stealth bomber). NOC's Aeronautics segment did $3.3B in Q1 2026, up 17% YoY.

Cash conversion varies sharply: KTOS and AVAV are both free-cash-flow negative (KTOS guided -$85M to -$95M FCF in FY2026; AVAV -$229M TTM) because they are investing in production capacity. NOC generates $3.1-3.5B guided FCF and LHX generates $2.6B TTM FCF.

Supply

Production capacity

• Kratos (KTOS) — Currently in low-rate Valkyrie production. Investing $135-145M in FY2026 capex (mostly unmanned systems and rocket motor facilities) to reach 40 Valkyries/year by end-2027. Also ramping Zeus and Oriole solid rocket motors (120 on order, deliveries start Q3 2026). Acquired Nomad (included in guidance) and pending Orbit Technologies acquisition (excluded). Sacramento, CA and Oklahoma City, OK production.
• AeroVironment (AVAV) — Produces Switchblade 300/600, Puma, Raven tactical drones, JUMP 20 medium UAS, and (post-BlueHalo acquisition) directed energy and space/cyber systems. BlueHalo closed May 2025, roughly doubling the company. Combined entity has capacity to produce thousands of small UAS per year. Added Freedom Eagle C-UAS interceptor line.
• L3Harris (LHX) — Supplies ISR sensors, EW payloads, space payloads, and secure communications for autonomous platforms built by others. Partnered with Joby Aviation on defense eVTOL variant (S-4T). Capacity bottleneck is in specialty electronics and cleared workforce, not assembly lines.
• Northrop Grumman (NOC) — Builds Triton maritime surveillance UAS and integrates autonomy into B-21. Investing $2.5B (company-funded) to boost B-21 production capacity by 25%. IBCS missile-defense C2 system is software — scales with deployment, not manufacturing. Aeronautics segment growing 17% YoY.

Key bottlenecks

• AI flight software and swarm coordination — Shield AI's Hivemind was selected for the DAWG LUCAS drone program. Autonomy software that can operate on any cheap drone frame is the explicit Pentagon goal; very few companies have proven it at scale.
• Security clearances — TS/SCI clearances take 12-18 months. Every autonomous weapons program requires cleared engineers, limiting hiring speed.
• Rad-hard and SWaP-constrained compute — autonomous drones in contested airspace cannot rely on cloud connectivity. On-platform AI inference chips have long lead times.
• Supply chain for expendable airframes — US manufacturing bases for cheap airframes are immature compared to China. DAWG prioritizes software over hardware partly because of this.

The gap

Pricing direction: Pentagon procurement is shifting from cost-plus (development) to fixed-price (production), which compresses margins for established programs but creates margin expansion opportunity as production scales and unit costs decline. Kratos's Valkyrie aims to cost a fraction of a manned fighter. Loitering munitions pricing is rising: AVAV's Q1 FY2026 bookings imply higher ASPs than FY2025, driven by Switchblade 600 (larger, more capable, higher price per unit than Switchblade 300).

The players

Market data as of Jun 2, 2026. KTOS: FY2025 10-K and FY2026 guidance (Feb 2026). AVAV: Q1 FY2026 8-K (Sep 2025). LHX: Q1 2026 press release (Apr 2026). NOC: Q1 2026 earnings (Apr 2026).

The price of exposure

KTOS — $63.27. 8.4x FY2026 guided revenue ($1.6-1.7B midpoint), ~75x FY2026 guided adj. EBITDA ($162M midpoint). Carries $561M cash, zero long-term debt. Base case guidance explicitly excludes large-scale Valkyrie production. If Kratos hits FY2027 targets (18-23% growth, ~11% EBITDA margin), that implies ~$1.95B revenue and ~$215M EBITDA, or ~55x forward EBITDA on FY2027. est.

AVAV — $204.35. 5.3x FY2026 guided revenue ($1.95B midpoint), 34x FY2026 guided adj. EBITDA ($310M midpoint). GAAP-unprofitable (net loss $224M TTM) due to $79.7M/quarter in BlueHalo purchase-accounting amortization. Non-GAAP EPS guided at $3.60-3.70, implying forward P/E ~55x. Funded backlog of $1.1B covers ~56% of FY2026 revenue at midpoint. BlueHalo added $726M in debt and diluted shares from 28M to 50M.

LHX — $308.12. 2.6x TTM revenue, 16.6x EV/EBITDA. Trailing P/E 33x; forward P/E 26x. $2.6B FCF against $57B market cap = 4.5% FCF yield. Record $40.7B backlog at 1.4x book-to-bill. Autonomous exposure is indirect (sensors, payloads, comms), ~10-15% of revenue est.. Missile Solutions planned IPO/spinoff could surface value separately. Dividend yield: 1.6%.

NOC — $536.59. 1.8x FY2025 revenue, 12.5x EV/EBITDA. Trailing P/E 16.8x; forward P/E 19x. $3.1-3.5B guided FCF against $76B market cap = 4.1-4.6% FCF yield. $95.6B record backlog = 2.2 years of revenue. Returned $2.9B to shareholders in FY2025 ($1.6B buybacks + $1.3B dividends) while investing $2.5B in B-21 capacity. IBCS is a uniquely high-value autonomous integration position. Dividend yield: 1.7%.

What to deep-dive next

• KTOS Valkyrie unit economics: Per-unit production cost vs. contract price. Kratos is building 12 units ahead of contract — what does this imply about confidence in definitized orders? $25-28M FY2026 capex earmarked for Valkyrie production.
• AVAV BlueHalo integration: $80M/quarter non-cash amortization and -$229M TTM FCF. When does purchase accounting burn off and GAAP earnings turn positive? SCDE segment did $169M in Q1 at only 2.2% adj. EBITDA.
• DAWG $54.6B reality check: The FY2027 request is orders of magnitude above FY2026 DAWG allocation. $53B of it is in a flexible reconciliation pot, not standard appropriations. Congressional markup outcome is the key variable.
• CCA Increment 2: Northrop Grumman's YFQ-48A is reportedly a candidate. A win would add a major autonomous aircraft production program to the Aeronautics segment already growing 17% YoY.
• Shield AI (private): Selected for DAWG's LUCAS drone with Hivemind AI. A potential IPO would create the most direct pure-play on autonomous combat AI software.
