Yes, it was not so much a deletion as er a reduction in the numbers because we were very mindful erm in  going through the requirement erm and not making significant changes as far as the U K was concerned and we needed to make some savings in cost if at all possible and therefore we carried out a very comprehensive review of all the items of role equipment such as drop tanks er pylons, explosive release units and those type of things which  had been  provisionally earmarked for a very high intensive and fairly long running conflict and it was felt that if we were to make some savings then it was a sensible balance to reduce those numbers on the basis that we could save some money in the programme but at the same time many of these items could be bought later on at relatively short notice, clearly not within a conflict but in the years to come.
