The decision to procure the P-8A Poseidon maritime patrol aircraft was taken following a rigorous assessment of a range of possible options, including different aircraft types. Amongst the factors considered were that it was a proven technology, and that it could be brought into service more quickly than the alternatives.
RAF P-8A Poseidon aircraft will be delivered in the same configuration as those operated by the US Navy. This was an important consideration in the investment decision as it helps to deliver economies of scale from being part of a larger programme, and ensures that configuration control and interoperability with a key ally are maintained. Moreover, the planned capability development and upgrade programme for the aircraft provides confidence that the P-8A Poseidon will meet current and future UK key user requirements. Consequently, there are no plans to introduce any UK-specific equipment onto the aircraft.
