The Royal Navy of UK mulls procuring 12 US made P-8A Poseidon ASW aircraft, to counter the Russian nuclear submarines, which are regularly patrolling the coast of Britain. The Poseidon will replace aging Nimrod types. Total £2 billion budget will be allocated to fund the programs.
The Boeing P-8 Poseidon (formerly the Multimission Maritime Aircraft or MMA) is a military aircraft developed for the United States Navy (USN). The aircraft has been developed by Boeing Defense, Space & Security, modified from the 737-800ERX.
The P-8 conducts anti-submarine warfare (ASW), anti-surface warfare (ASUW), and shipping interdiction, along with an electronic signals intelligence (ELINT) role. This involves carrying torpedoes, depth charges, SLAM-ER missiles, Harpoon anti-ship missiles, and other weapons. It is able to drop and monitor sonobuoys.
It is designed to operate in conjunction with the Northrop Grumman MQ-4C Triton Broad Area Maritime Surveillance unmanned aerial vehicle. The aircraft was ordered by the Indian Naval Air Arm as the P-8I Neptune, with the Royal Australian Air Force expected to place an order.
