Buy off the shelf - behave!!!! Surely we'll need a bespoke device capable of sustaining 30g whilst 10000ft underwater with a security system that requires three separate dongles and five passwords. It will be at least five times the size of an iPad and use it's own OS making it incompatible with the rest of NATO. And it must be designed and produced by BAE Systems. Although in fairness, and to balance the discussion, the requirement will be changed by the MOD on a monthly basis with the budget being reduced accordingly. The project manager will also be changed by the MOD every 6 months to ensure a 'fresh approach'.
I can hear industry rubbing their hands together in anticipation!
