UUVs to stalk hostile submarines

Two high-profile events from the past three years have served to highlight the growing importance of the Unmanned Underwater Vehicle (UUV) in naval operations.

The first incident saw the Royal Navy minehunter HMS Brocklesby, operating off Libya in May 2011 as part of the NATO mission to enforce UN Security Council resolutions, deploy a SeaFox UUV to destroy a buoyant mine laid by pro-Gaddafi forces outside Misrata harbour. Subsequently, in August 2012, the US Navy sent dozens of SeaFox UUVs to the Persian Gulf after the Iranian government threatened to use its arsenal of Soviet-era mines to blockade the Strait of Hormuz, a move that would have effectively shut down a major proportion of the world's oil supplies.

Naval hydrographic and oceanographic units are using UUVs equipped with a wide array of sensors to chart the seabed and/or determine the characteristics of a given body of water, providing essential data for planning submarine and amphibious operations. Unmanned submersibles are also employed on search-and-rescue and intelligence, surveillance and reconnaissance missions. Meanwhile, trials have commenced in the US that will result in the introduction of a new class of deep-diving UUV designed to stalk hostile submarines.
