Unmanned Underwater Vehicles (UUV) Market

The unmanned underwater vehicle (UUV) market is projected to grow from USD 6.91 billion in 2026 to USD 19.22 billion by 2031, registering a CAGR of 22.7%. In terms of volume (new deliveries), the market is projected to reach 67,263 units by 2031, up from 22,845 units in 2026. This growth is largely driven by the rising use of AUVs and ROVs for naval surveillance, mine countermeasures, offshore inspection, seabed mapping, and marine monitoring. Demand is also supported by the need to reduce diver risk, cut vessel dependency, and collect underwater data more often and more safely.

Key market players include Kongsberg (Norway), Saipem (Italy), BAE Systems (UK), L3Harris Technologies, Inc (US), and Oceaneering International, Inc. (US). These companies have employed various organic and inorganic growth strategies, including collaborations, acquisitions, product launches, partnerships, agreements, and expansions, to enhance their international footprint and capture a significant share of the UUV market. These strategies have enabled them to expand their reach across geographies.
