L3Harris Lands US Navy Work Spanning Submarine Masts and Missile Hardware

L3Harris Technologies has secured contract awards from the US Navy covering two distinct areas: submarine mast systems and missile components, according to a report by Naval Technology citing the company’s announcements.

The submarine-related award concerns mast assemblies — the retractable structures submarines raise above the surface for sensors, communications, and other functions. The second award involves components used in missile programmes, adding to L3Harris’ substantial backlog of work with the US Department of Defense.

The wins underscore the Melbourne, Florida-based company’s positioning across naval and munitions supply chains. L3Harris, which trades on the New York Stock Exchange under the ticker LHX, operates through three business segments: Space & Mission Systems, Communications & Spectrum Dominance, and Missile Solutions. The missile-components award aligns most directly with the Missile Solutions segment, which has been a growth area as demand for munitions replenishment has risen across Western defence ministries.

In afternoon trading, LHX shares stood at $252.52, down 1.26% from the previous close of $255.74. The company’s market capitalisation was approximately $48.81 billion, placing it among the largest publicly traded defence contractors in the Industrials sector’s Aerospace & Defense industry.

Submarine mast work is a specialised niche with few qualified suppliers, given the engineering and certification requirements involved in systems that must operate reliably across repeated surfacing cycles. Long-term naval contracts in this category typically provide steady revenue visibility rather than headline-scale awards, and they complement the larger platform primes’ shipbuilding programmes.

For the US Navy, sustaining and upgrading the undersea fleet’s existing systems has been an increasing area of contract activity as the service balances new boat construction with maintaining current vessels. Suppliers like L3Harris sit deeper in that supply chain, delivering subsystems integrated by the Navy’s prime shipbuilders.

The company has been reshaping its portfolio in recent years toward what it describes as mission-critical solutions for government and commercial customers worldwide, including divestitures of non-core assets and acquisitions in space and defence technology. Continued order flow in both maritime subsystems and missile components would be consistent with that strategy.

Neither the total contract value nor the delivery timeline was detailed in the report, and DefencePressWire has not independently confirmed the award terms.
