L3Harris Navy contract activity continued this week as the US Navy awarded the company a 22.9 million dollar deal for production of the Towed Body 34A sonar system, according to official contract documents released by Naval Sea Systems Command.
The award supports undersea warfare capabilities across the surface fleet and reflects sustained Navy investment in passive acoustic sensing systems designed to detect and track submarines in contested maritime environments.
Contract Overview and Scope
L3Harris Corp., based in Millersville, Maryland, received a fixed price incentive contract valued at 22,900,118 dollars for production, integration, and testing of the Towed Body 34A towed array system. The contract carries a firm target structure and includes options that could raise the total value to 65,470,348 dollars if fully exercised.
Naval Sea Systems Command in Washington, DC, is the contracting authority. The award was competitively procured through the System for Award Management platform, with two offers submitted.
Work under the contract will be spread across multiple L3Harris facilities. Production and support activities will take place in Millersville, Maryland at 25 percent, Liverpool, New York at 40 percent, and Ashaway, Rhode Island at 35 percent. Contract completion is expected by July 2028.
What Is the Towed Body 34A
The Towed Body 34A is a passive sonar system designed to be deployed behind surface ships to improve detection of submarines and other undersea threats. Towed array systems increase acoustic sensitivity by distancing sensors from ship noise, allowing improved performance in complex ocean conditions.
These systems play a central role in anti submarine warfare missions, especially for destroyers and other surface combatants tasked with protecting carrier strike groups and key sea lanes. While the Navy did not release platform specific details, Towed Body systems are commonly associated with fleet wide undersea surveillance upgrades.
Funding Breakdown and Budget Context
Funding for the L3Harris Navy contract comes from multiple fiscal year appropriations. At the time of award, the Navy obligated 1,964,476 dollars from fiscal year 2024 shipbuilding and conversion funds, representing 11 percent of the total. An additional 1,964,476 dollars from fiscal year 2025 shipbuilding and conversion funding also accounts for 11 percent.
The remaining 14,518,946 dollars, or 78 percent, comes from fiscal year 2026 other procurement Navy funding. All obligated funds will not expire at the end of the current fiscal year, allowing work to continue across multiple budget cycles.
This mix of shipbuilding and procurement accounts reflects how undersea warfare systems are integrated into both new construction and in service upgrades.
Competitive Award and Industry Context
The L3Harris Navy contract was awarded following a competitive process, underscoring continued competition in the naval sonar and undersea systems market. L3Harris has a long standing role as a supplier of acoustic sensors, electronic systems, and mission equipment for the US Navy and allied fleets.
The company supports a range of maritime programs including sonar arrays, electronic warfare systems, and integrated combat system components. Its distributed production footprint for the Towed Body 34A aligns with broader defense industrial base efforts to sustain skilled manufacturing across multiple states.
Importance for US Naval Strategy
Undersea warfare remains a core priority for the US Navy as peer competitors expand submarine fleets and invest in quieter, more capable platforms. Passive sonar systems such as the Towed Body 34A provide a key layer of situational awareness without revealing ship position through active emissions.
By continuing investment in towed array systems, the Navy aims to maintain an advantage in detection range and tracking accuracy, particularly in high traffic or acoustically challenging regions. Programs like this also support fleet readiness by ensuring legacy systems are refreshed with updated production and testing standards.

Closing
The L3Harris Navy contract for the Towed Body 34A highlights continued investment in undersea sensing as the service modernizes its surface fleet. With work scheduled through 2028 and options that could significantly increase contract value, the program reinforces the importance of acoustic dominance in future naval operations.
