The P-8 Poseidon joins an integrated UK force of ships, submarines and helicopters in the anti-submarine warfare role. Poseidon's introduction marks a significant upgrade in the UK's ability to conduct anti-submarine operations, combined with a weapons system to counter these threats. The Poseidon is designed to conduct long range patrols providing extended surveillance missions at high and low altitudes. It is equipped with cutting-edge sensors which use high-resolution area mapping to find both submarines and surface vessels. It will also integrate seamlessly with our NATO allies. This will maintain operational freedom for our own submarines and apply pressure to those of our potential foes.
