Have flown both.
1. Nimrod nicer to fly.
2. Some P-3 variants now surpassing Nimrod in capability.
3. P-3 an obvious interim acquisition if the RAF can get them.
4. Have to be careful on the variant and exact avionics or you'll be in the same spot as the Nimrod with spares....
5. Cockpit size is no factor, the seats are the same size.....if you get up and walk around, you're not confined to the Fight Deck!!
Bring on the P8 I say...and all operators should get some!!!
