L3Harris Technologies awarded $139 million Navy contract for submarine masts
A $139 million contract modification puts L3Harris Technologies (LHX) in focus on the defense procurement tape, with the U.S. Navy the contracting authority and submarine masts the named deliverable. The modification structure places this work inside an existing program rather than a fresh competitive solicitation.
Key takeaways
- L3Harris Technologies received a $139 million U.S. Navy contract modification for submarine masts.
- The award was made through a modification to an existing program rather than a new competitive solicitation.
- Proceeding by modification keeps the existing supply relationship intact and signals the incumbent's standing on the program.
- The award's contribution to L3Harris's backlog, throughput timelines, and program duration remain undisclosed.
- Submarine masts are platform-critical hardware covering above-waterline systems that connect a submerged vessel to its operating environment.

The confirmed figure is $139 million. L3Harris Technologies is the named contractor. Submarine masts are a platform-critical hardware category for submerged naval operations, covering the above-waterline systems that connect a vessel to its operating environment while it remains below the surface. The Navy's choice to proceed through modification rather than re-compete keeps the existing supply relationship intact, and that continuity carries its own operational signal about the incumbent's standing on the program.
Throughput timelines and the modification's contribution to L3Harris's backlog remain undisclosed, leaving the capacity and lead-time picture for the company's production operations open for now.
The next confirmable development is any filing or earnings commentary from L3Harris Technologies that attaches a program duration or specific backlog figure to this award.
