L3Harris Technologies has secured two new contracts from the US Navy, covering submarine mast systems and missile propulsion components.
The first contract, valued at $139m and awarded by the US Naval Sea Systems Command, extends L3Harris’ role in supplying Low-Profile Masts (LPM) for Virginia– and Columbia-class submarines.

These telescoping masts, equipped with visible and infrared imaging, replace traditional periscopes and are intended to enhance stealth and situational awareness.
According to L3Harris, LPMs offer 360-degree visibility along with improved optical and sensor capabilities for the US Navy’s nuclear submarine fleet.
As prime contractor, and design agent for the LPM programme, the company will deliver engineering support, design, and testing services for the LPM Type 20 and Type 24 systems through to their delivery to the US Navy fleet.
L3Harris maritime, space and mission systems president Nino DiCosmo said: “Delivering decisive undersea superiority capabilities to our sailors is at the core of everything we do, and this follow-on award is a testament to that proven commitment.
“The LPM represents a critical leap forward in submarine stealth and situational awareness, ensuring our fleet maintains superiority beneath the waves for decades to come.”
In a separate development, L3Harris signed a multi-year agreement with the Naval Air Warfare Centre Weapons Division (NAWCWD) China Lake to manufacture critical missile components for munitions including Raytheon’s Tomahawk cruise missile.
L3Harris has been supplying components for the Tomahawk missile for over three decades, including the Mk 135 solid propellant booster and the blast-fragmentation warhead.
In addition, the company previously entered into a partnership with the Naval Surface Warfare Centre Indian Head Division to expand manufacturing of Mk 104 solid dual thrust rocket motors, which serve as the second stage propulsion for Raytheon’s Standard Missile programme.
L3Harris propulsion systems, missile solutions president Scott Alexander said: “Collaborating with our US Navy partners strengthens the supply chain, allowing us to expand our manufacturing capabilities to fulfil urgent national security mission requirements.”
In July this year, L3Harris secured a contract to supply battery monitoring systems for the Virginia– and Columbia-class submarine programmes.
