Lockheed Martin agreed to acquire Ultra Maritime, a provider of sonar, acoustic sensors and undersea warfare systems for naval defense customers, from Advent International for $3.45 billion.

The sale follows Booz Allen Hamilton’s June purchase of Ultra Mission Solutions from Advent’s Cobham Ultra Group, further streamlining the sponsor’s defense technology holdings.

Ultra Maritime’s technology supports anti-submarine warfare, mine detection and maritime surveillance platforms.

Lockheed Martin, a prime defense contractor, plans to integrate the sensor capabilities into its naval combat systems.
