What we actually need is 5/6 C130J (Mk4s) fully equipped with externals, decent floor and winch, RWR, etc, etc.
This 'mini-fleet' could be put to very good use releasing 5/6 'standard' C130Js back to the strat/tac AT pool.
The C130Ks are sha**ed - and yes we did sell a load off as part of the C130J buyback scheme. Each one went with external tanks and cupola! - most of them were Mk1s as well - the platform that has suffered the worst combat attrition.
However, if we don't decide to buy them now it will almost be too late - we need to plan for the next conflict/operation.
