"you could probably buy 2 or 3 Hawk 200s for the price of one Typhoon."
where's the extra manpower coming from?
Probably the crews already factored into T3 of Typhoon manning plot, those F3, Jag, GR9 and 15 GR4 crews that are still floating around the system (those that haven't PVRd / left at options) and being drawing flying pay for flying a desk.
Tucano is a nice idea, but when you take into account the need to buy it, fit it for wpns, test it, incorporate DAS, bring it in to service, get it to Afghan, realise you can't actually carry much in Afghan's hot / high conditions, realise that it isn't as quick as you thought it might be and that you can't also fulfil the UK AD role like you could with the Hawk 200 or similar, then the Tucano has a lot of issues it needs to get past before it could even be considered.
