BAE Systems' £10m investment will fund its research of new technologies such as artificial intelligence, information and electronic warfare, unmanned vehicles and new weapons and as a result of the funding, the MISC will receive new facilities including a visualisation suite capable of displaying live tactical data from any Royal Navy warship anywhere in the world, further enhancing warship support.
