Arclite01 in answer question 4.
25 is what is wanted and what we signed up for. EADS want more money. We might get 19 according to one report to offset the cost increase, or 25 if through-life support costs can be drastically reduced (even if we have to pay more towards the programme on the old HM Government overdrawn credit card) - we might even get none, especially if no solution between the programme partners is found in regards to the cost increase. Deliveries? MSN001 flew today and is about to land as I write this. MSN002 and MSN003 first flights next year, MSN004 and MSN006 in 2011 (missing one MSN005 is static airframe). Deliveries to the French (launch customer) from end-2012. I think the RAF from 2013. That's if the test programme now runs smoothly.
