The US Navy submarine countermeasures program received a significant boost with a new $59.6 million contract awarded to Ultra Maritime for production of acoustic device countermeasures used on in-service submarines. The award supports continued modernization of undersea self defense systems as the Navy focuses on survivability in increasingly contested maritime environments.
The contract was awarded on January 26, 2026, by Naval Sea Systems Command, or NAVSEA, and covers production of MK3 and MK4 acoustic device countermeasures along with associated launch tubes.
Contract Details and Scope
Ultra Maritime, based in Braintree, Massachusetts, was awarded a mixed contract structure that includes firm fixed price, cost plus fixed fee, and cost indefinite delivery indefinite quantity elements. The total contract value is $59,603,232.
The work will be performed at Ultra Maritime facilities in Braintree and is scheduled for completion by January 2031. The long performance period reflects sustained production in support of the US Navy submarine fleet rather than a one time delivery.
Funding for the initial delivery order includes $8,500,333 from fiscal year 2026 other procurement Navy funds and $1,152,032 from fiscal year 2025 other procurement Navy funds. These funds will not expire at the end of the current fiscal year, allowing program stability across budget cycles.
The specific delivery order, N00024-26-F-6227, falls under the broader contract vehicle N00024-26-D-6214.
Competitive Procurement Process
According to the award notice, the requirement was competitively procured through full and open competition using the System for Award Management. One offer was received in response to the solicitation.
While only a single offer was submitted, the Navy followed federal acquisition regulations for competitive procurement, reinforcing transparency and compliance with defense contracting standards. NAVSEA, headquartered in Washington, DC, is the contracting activity.
Role of Acoustic Device Countermeasures
Acoustic device countermeasures play a critical role in submarine survivability. Systems such as the MK3 and MK4 are designed to confuse, decoy, or degrade the effectiveness of hostile torpedoes by emitting acoustic signals that divert threats away from the submarine.
As potential adversaries continue to invest in advanced undersea sensors and torpedo technologies, the importance of reliable acoustic countermeasures has grown. These systems are a key layer in the Navy’s undersea defensive architecture, complementing stealth, maneuvering tactics, and electronic warfare capabilities.
The US Navy submarine countermeasures portfolio is particularly relevant as near peer competitors expand their undersea warfare capabilities in both the Indo Pacific and Atlantic theaters.
Ultra Maritime and Undersea Warfare Expertise
Ultra Maritime is a long established supplier of undersea warfare systems to the US Navy and allied navies. The company specializes in sonar, anti submarine warfare, and acoustic solutions across surface ships, submarines, and unmanned platforms.
This latest award reinforces Ultra Maritime’s role as a trusted supplier in the US Navy submarine countermeasures ecosystem. By sustaining production through 2031, the Navy ensures continuity in support for existing submarine classes without introducing integration risk from new vendors.
The contract also supports domestic defense manufacturing, with all work performed in Massachusetts.
Strategic Context for the US Navy
The award aligns with broader US Navy priorities focused on maintaining undersea dominance. Submarines remain one of the most survivable and strategically valuable assets in the US military, supporting deterrence, intelligence collection, and power projection.
Recent Navy budget documents and statements from Department of Defense leadership have emphasized the growing importance of undersea warfare as rival navies invest heavily in anti submarine capabilities. Ensuring that in-service submarines are equipped with effective countermeasures is a cost effective way to maintain operational advantage.
Within this context, the US Navy submarine countermeasures program represents a relatively small but essential investment compared to major platform acquisition programs.
Budget and Program Stability
The use of other procurement Navy funds and the non expiring nature of the obligated amounts provide flexibility for program execution. This funding approach helps reduce disruptions caused by continuing resolutions or delayed appropriations.
Long term production contracts such as this also help stabilize the industrial base by allowing suppliers to plan workforce and supply chain requirements with greater confidence.
Outlook
With work extending through early 2031, the Ultra Maritime contract ensures continued availability of MK3 and MK4 acoustic device countermeasures for the US Navy submarine fleet. While the award does not introduce new capabilities, it reinforces the sustainment and readiness of critical defensive systems already in service.
As undersea competition intensifies, investments in systems that protect existing platforms remain a cornerstone of US naval strategy.
