AQAfive - The Nimrod (HS801) came about purely thanks to the suddenly issued Operational Requirement (OR 381) which effectively negated all the previous work for OR 357 and was written almost completely around the Atlantique! Hawker Siddely took 7 days to come up with the 801 (Nimrod) using mainly existing Comet parts and won the contest. It was announced in 1965, first flew in 67 and front line deliveries started in 69. However, whilst it was an excellent aircraft for its time, as alluded to above it was still essentially a 1940-50 design. What might we have had had the original OR 357 winner been built. Not a P-8 certainly, but maybe we wouldn't have been in a position of needing it now either.
