Defense prime Lockheed Martin [NYSE: LMT] has officially finalized its $3.45 billion acquisition of global Anti-Submarine Warfare (ASW) and undersea domain specialist Ultra Maritime.
The transaction—originally agreed upon with Advent International’s Cobham Ultra in July 2026—brings Ultra Maritime’s advanced sonar systems, sonobuoys, torpedo defense mechanisms, and uncrewed subsea sensing suites under Lockheed Martin’s Rotary and Mission Systems (RMS) business unit. The strategic alignment aims to integrate Ultra Maritime’s acoustic sensor manufacturing and international naval footprint directly into Lockheed Martin’s broader surface combatant, airborne ASW (MH-60R / P-8A integration), and uncrewed autonomous undersea vehicle (AUV) architecture.

TIMES OF DEFENCE ASSESSMENT
Lockheed Martin’s $3.45 billion buyout of Ultra Maritime represents a consolidation of subsea sensor manufacturing within the Western defense industrial base. As adversary submarine fleets transition toward quieter propulsion systems, deep-sea endurance, and uncrewed underwater vehicle (UUV) deployments, maintaining domain awareness across critical chokepoints requires dense, multi-static acoustic sensor networks.
From an engineering and integration perspective, absorbing Ultra Maritime directly into Lockheed Martin RMS bridges a key hardware-to-software gap. While Lockheed Martin dominates airborne (MH-60R, P-8A systems integration) and surface/subsurface combat management systems (Aegis, AN/BYG-1), Ultra Maritime brings vertical ownership of sonobuoys, towed arrays, and acoustic signal processing hardware. Combining Ultra’s acoustic hardware with Lockheed Martin’s edge-computing algorithms and mission systems allows the combined entity to deliver turnkey, end-to-end ASW combat packages—from sonobuoy drop to combat-system fire control—to U.S., NATO, and AUKUS naval forces.
