Kongsberg Discovery acquires U.S. underwater acoustics firm Sonatech

The transaction is expected to close later in 2025, pending the required governmental approvals. This marks a significant step in strengthening Kongsberg Discovery’s presence in the U.S. market.

With over 50 years of experience, Sonatech is a prominent engineering and manufacturing firm in the U.S. defence sector, supporting key undersea acoustics projects for the U.S. Navy. Kongsberg Discovery sees this move as an opportunity to expand in a critical market.

“Sonatech has a strong and solid relationship with the U.S. Navy,” said Martin Wien Fjell, President of Kongsberg Discovery. “With our combined technology portfolio and expertise, we will broaden the systems and products available for the U.S. Navy. Acquiring Sonatech will provide Kongsberg Discovery with a platform to leverage its technology into new markets and further development. It will also reinforce our presence and operations in the U.S., a significant market for us.”

Sonatech is known for its advanced sonar solutions and technical expertise in design, development and manufacturing. Its technologies are integrated into nearly every class of U.S. Navy underwater systems.

Mark Shaw, President of Sonatech, welcomed the acquisition as a step forward for the company’s future. “We have provided reliable, high-performance acoustic products and technical services to meet the demanding specifications of the U.S. Navy and other clients for half a century. We are thrilled to become a part of the Kongsberg Discovery family. Together we are set to expand further and capture opportunities beyond what each of us could do alone,” he stated.

Geir Håøy, CEO and President of KONGSBERG, highlighted the strategic fit of Sonatech within the group’s broader goals. “As a global technology company and ocean space expert, we are developing world-leading solutions from deep sea to outer space. Mapping the oceans is becoming increasingly important with the world’s need for security and sustainability. The acquisition of Sonatech fits well into our technology portfolio and our growth ambitions. It strengthens our position in both safety, research and sustainable management of marine resources,” Håøy said.

Based in Santa Barbara, California, Sonatech employs over 110 professionals and reported a revenue of USD 33 million in 2024. The company specialises in the development and production of customised acoustic systems for underwater applications.
