L3Harris

L3Harris builds the sensing, communications, mission-systems and propulsion hardware that connects military platforms into a functioning force. Its products include tactical radios, electronic-warfare systems, infrared and other sensors, missionized aircraft systems, maritime electronics, missile-warning satellites and rocket motors.

The strongest 2026 strategic thread is missile defense. L3Harris can help detect and track a missile from orbit through the Space Development Agency's Proliferated Warfighter Space Architecture, while Missile Solutions supplies propulsion and control hardware used in interceptors including PAC-3 Missile Segment Enhancement and Terminal High Altitude Area Defense. That breadth gives L3Harris exposure to both the sensor layer and the interceptor industrial base.

Space & Mission Systems

Missile-warning and missile-defense satellites, infrared payloads, intelligence, surveillance and reconnaissance aircraft missionization, maritime systems, secure mission networks and civil-airspace infrastructure. L3Harris holds both Tranche 3 and Accelerated Missile Defense Tranche 3 awards for SDA's Tracking Layer and has more than 70 missile-tracking and defense satellites on order across SDA and Missile Defense Agency programs.

Communications & Spectrum Dominance

Tactical and airborne radios, resilient networks, night vision, electronic warfare, threat sensing and targeting. Q1 2026 revenue was $1.86B with a 25.1% operating margin, making this the company's highest-margin reportable segment.

Missile Solutions

Solid rocket motors, liquid divert and attitude control, hypersonic propulsion and other missile components inherited largely through the 2023 Aerojet Rocketdyne acquisition. Priority programs include PAC-3 MSE, THAAD, Tomahawk and Standard Missile. The Department of War invested $1B in the business in April 2026 to expand capacity ahead of a proposed public offering.

Counter-UAS and Mission Effects

VAMPIRE and related counter-uncrewed-aircraft systems pair sensors, fire control and low-cost effectors for mobile defense against drones. The Army's June 2026 order signals movement from demonstration toward production-scale fielding.

L3Harris was created in 2019 through the merger of Harris Corporation and L3 Technologies. The combination joined tactical communications, sensors, avionics, space payloads and defense electronics under one company. The 2023 acquisition of Aerojet Rocketdyne added strategic, missile-defense, tactical and space propulsion capabilities.

Effective 05-JAN-2026, L3Harris reorganized from four reportable segments to three: Space & Mission Systems, Communications & Spectrum Dominance and Missile Solutions. In March, Sam Mehta was given responsibility for both Space & Mission Systems and Communications & Spectrum Dominance while Ken Bedingfield remained focused on Missile Solutions.

The portfolio is still being reshaped. AE Industrial Partners agreed to acquire about 60% of a new space-technology company built from selected Space Propulsion and Power Systems and Space Avionics & Communications assets, with L3Harris retaining about 40%. The SEC filing values that transaction on a net-enterprise-value basis at $825M, while the company announcement cited an $845M total enterprise value. Closing remained expected in the second half of 2026. The RS-25 engine business is excluded from the transaction.

On 23-APR-2026 the Department of War closed a $1B investment in Missile Solutions through convertible preferred securities and warrants. Six days later, L3Harris announced that it had confidentially submitted a draft Form S-1 for a proposed Missile Solutions initial public offering. The offering remains subject to SEC review, market conditions and final terms.

Q1 2026 revenue was $5.744B, up 11.9% from $5.132B a year earlier and up 15% organically. Space & Mission Systems grew 24% to $2.99B on classified and international missionized-aircraft programs, space, mission networks and maritime work. Communications & Spectrum Dominance grew 3% to $1.855B, while Missile Solutions grew 18% to $990M on higher missile, munition and space-propulsion production.

Orders of $7.8B produced a 1.4x book-to-bill ratio and pushed contractual backlog to $40.7B. The company expects roughly 40% of that backlog to convert to revenue within 12 months and about 65% within 24 months. Backlog is companywide and should not be described as defense-only backlog.

Management's current 2026 guidance calls for $23B to $23.5B in revenue, low-16% segment operating margin, GAAP diluted EPS of $11.40 to $11.60 and about $3.0B of free cash flow. The largest near-term growth variable is industrial capacity: L3Harris is adding or upgrading nearly 1 million square feet across solid-rocket-motor sites while new PAC-3 MSE and THAAD framework agreements contemplate major production-rate increases if final contracts are definitized.

The space side is becoming more consequential. SDA's July 2026 AMDT3 award gives L3Harris a roughly $955M potential agreement for 18 HBTSS-like missile-defense satellites, on top of its approximately $843M Tranche 3 tracking award from December 2025. These satellites are designed to produce the quality of tracking data needed to support missile defense, not merely missile warning.

The propulsion side may be even more strategically constrained. The Department of War and Lockheed Martin framework agreements announced on 27-JUL-2026 contemplate nearly tripling L3Harris PAC-3 MSE propulsion output and quadrupling THAAD propulsion output. That turns factory throughput, supplier health and quality control into strategic variables. The agreements are not yet definitized, so the capital case depends on conversion from framework to funded production contracts and on L3Harris executing the ramp without eroding margins.

The other major catalyst is corporate. Missile Solutions is preparing for a proposed public offering after the Department of War's $1B investment. Until the offering terms are public and the transaction closes, investors should treat ownership, valuation and proceeds as unresolved rather than settled.

L3Harris' moat comes from three things that are slow to reproduce: installed communications and electronic-warfare systems, classified mission access and scarce missile-propulsion capacity. Its radios and mission electronics are embedded across U.S. and allied forces. Its space programs require trusted access, specialized infrared payload expertise and recurring program performance. Its propulsion business sits behind interceptors that cannot be fielded at scale without motors, control systems and qualified production lines.

The weakness is that this moat is operational, not software-like. It must be re-earned through manufacturing quality, schedule performance and capital spending. A factory bottleneck can strengthen pricing and strategic relevance, but the same bottleneck becomes a liability if yields, suppliers or labor cannot support the promised ramp.

Missile Solutions transaction risk: the proposed IPO remains subject to SEC review, market conditions, final capitalization and offering terms. The Department of War investment will convert into equity under specified conditions, which adds unusual governance and dilution considerations.

Production-ramp risk: PAC-3 MSE and THAAD frameworks require large increases in output. New buildings and equipment do not automatically create qualified production. Supplier capacity, energetics, inspection, labor and yield must scale together.

Framework versus funded award risk: the 27-JUL agreements are important demand signals but are not yet definitized production contracts. Revenue, backlog and contract values should not be booked from public framework language alone.

Fixed-price and program-execution risk: L3Harris carries firm-fixed-price and other performance-sensitive contracts across satellites, mission systems and propulsion. Cost growth or schedule slips can compress margins even when demand is strong.

Government concentration: U.S. government agencies, prime contractors and allied governments dominate the customer base. Appropriations, continuing resolutions, export approvals and acquisition-policy shifts can move order timing.

Portfolio-shaping risk: the AE Industrial space-technology transaction is still expected to close in the second half of 2026. Until closing, the assets remain within L3Harris reporting and guidance.
