RTX: $251B Backlog and a Deliberate Pivot Toward Autonomous Weapons Systems

RTX enters 2025 as the world's largest aerospace and defense company by revenue, with $80.7B in 2024 sales and a $251B backlog that provides roughly three years of forward revenue visibility. What makes the company strategically relevant to the autonomous systems market is not its size but its trajectory: a systematic effort to layer AI and autonomy onto an existing installed base of fielded hardware — 3,000+ Multi-Spectral Targeting Systems across 44 variants, Patriot batteries on four continents, and propulsion systems aboard the F-35 — while simultaneously competing for new autonomous platform programs from a position of deep institutional credibility.

Business Overview

RTX operates through three segments: Pratt & Whitney (propulsion), Collins Aerospace (avionics and mission systems), and Raytheon (weapons and sensors). In FY2025, Pratt & Whitney became the largest segment at $32.92B in revenue — up 17.28% year-over-year — driven by commercial engine deliveries, F135 aftermarket demand, and military production. Raytheon recorded $28.04B in 2025 sales, with Q3 2025 alone generating $9B in contract awards across Patriot, SM-6, and AMRAAM programs. Collins Aerospace contributed $30.2B in full-year 2025 sales.

Free cash flow stood at $4.5B in 2024, with management guiding to $7.0–7.5B in 2025 and $8.25–8.75B in 2026 — a near-doubling over two years that funds both R&D and a shareholder return program exceeding $33B since the 2020 merger.

Segment	FY2025 Revenue	Key Programs
Pratt & Whitney	$32.92B	F135 (F-35), PW500 (Talon Blue), commercial aftermarket
Collins Aerospace	$30.2B	RapidEdge™ C2, avionics, air traffic modernization
Raytheon	$28.04B	Patriot, AMRAAM, SM-6, LTAMDS, Coyote, PhantomStrike
RTX Total (2024)	$80.7B

Technology and Autonomous Systems Portfolio

RTX's autonomous systems strategy operates on two tracks: upgrading fielded hardware with AI software, and competing for new autonomous platform contracts.

On the upgrade track, the Shield AI partnership — announced July 2025 and fully self-funded without government investment — integrates Shield AI's Hivemind AI stack with RTX's Multi-Spectral Targeting System and ViDAR sensor autonomy software to target maritime and airborne swarm threats. The self-funded structure is a meaningful signal: both companies are committing capital without a government cost-plus backstop, indicating commercial confidence in near-term demand.

On the new platform track, RTX has secured two significant footholds. PhantomStrike radar was selected in December 2025 for integration with U.S. Air Force autonomous fighter jets. Pratt & Whitney's PW500 engine was selected to power Northrop Grumman's YFQ-48A Talon Blue autonomous wingman in April 2026, inserting RTX into the Collaborative Combat Aircraft (CCA) program at the propulsion layer.

The Coyote UAS — Raytheon's most mature autonomous platform — achieved a notable milestone in February 2026 when its non-kinetic variant defeated multiple drone swarms in testing. Coyote operates with a human-on-the-loop architecture and has been demonstrated at U.S. Army EDGE exercises alongside Collins Aerospace's RapidEdge™ command-and-control system.

AI is also being applied to production. RTX's proprietary AI tools for Patriot missile manufacturing have more than doubled output — a capability that directly addresses the U.S. military's munitions replenishment priorities. The U.S. Navy's FY2027 request for 785 Tomahawk missiles ($3B, a 1,200% increase from FY2026) signals the scale of demand RTX's production systems must absorb.

Market Position

RTX's competitive moat rests on vertical integration that no single competitor replicates: propulsion (Pratt & Whitney), avionics and C2 (Collins Aerospace), and weapons and sensors (Raytheon) under one balance sheet. Lockheed Martin carries a $179B backlog but lacks equivalent propulsion assets. Northrop Grumman owns the B-21 program and deep autonomy expertise but operates at roughly half RTX's revenue scale.

The primary structural risk in the autonomous systems context is software ownership. RTX does not control the Hivemind AI stack — that belongs to Shield AI. If the NCA weapon system proves operationally significant, RTX's leverage in that relationship warrants monitoring. The company's autonomous strategy is hardware-led and partnership-dependent for the AI layer, which creates a different risk profile than AI-native defense entrants building software-first.

The Pratt & Whitney powder metal contamination issue, which required $3B+ in charges and ongoing fleet inspections, remains an execution overhang on the segment generating 36% of revenue. MODERATE CONFIDENCE that remediation costs are substantially provisioned; escalation risk persists.

Outlook

Three near-term catalysts carry the most weight for RTX's autonomous systems positioning: the Hivemind/NCA weapon system moving from prototype to operational demonstration; PhantomStrike advancing through Air Force autonomous fighter integration milestones; and potential large-scale CCA production contracts as the autonomous wingman program matures beyond the YFQ-48A competition phase.

The $251B backlog, free cash flow inflection toward $8.5B, and 2025 revenue guidance of $83.0–84.0B provide the financial foundation to sustain parallel investment across all three. Christopher Calio, elevated to combined Chairman and CEO in April 2025, delivered 11% organic sales growth and 13% adjusted EPS growth in 2024 with margin expansion across all segments — a track record that supports execution confidence on the autonomous pivot. HIGH CONFIDENCE on financial trajectory; MODERATE CONFIDENCE on autonomous systems timeline given prototype-stage status of key programs.
