Huntington Ingalls to acquire Hydroid

04 February 2020

US shipbuilder Huntington Ingalls Industries (HII) has agreed to buy Hydroid, an American manufacturer of unmanned underwater vehicles (UUVs), from Norway's Kongsberg Maritime for USD350 million.

HII said on 4 February that the acquisition will expand its capabilities "in the strategically important and rapidly growing autonomous and unmanned maritime systems market".

Hydroid makes the Remus line of UUVs, which are torpedo-shaped, electric propeller-driven vessels that include defence applications such as mine detection and intelligence as well as surveillance and reconnaissance.

HII's existing UUV work includes developing the Proteus optionally manned prototype for the US Navy (USN) and working with Boeing to produce the new Orca Extra Large UUV (XLUUV) for the USN.
