Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the (a) CPI, (b) SPI and (c) cost variance is of the P-8A programme.

For technical reasons, the CPI and SPI for the P-8A (Poseidon MRA1) programme are set at 1.00 as the Government-to-Government Foreign Military Sale arrangement under which the UK is acquiring the aircraft does not include the use of Earned Value Management. The most recent forecast of the cost of the acquisition programme shows that it is expected to be below the approved cost. All nine aircraft ordered for the Royal Air Force have now been delivered.
