I do agree there is a need for CHF to be kept with its amphibious focus and capibility that can be deployed on ships if we still have an amphibious fleet in the future!
As it seams that the Puma LEP is the way ahead Maroon man's idea is a good way ahead but I would sugest that FSH programme be split to purchase a version of the Merlin with more powerful engines folding rotors and tail to replace the Seaking HC4 preferable on a 1 for 1 basis of the HC4 fleet. hopefully sorting out some of the HC3's short commings and when the HC3 is refurbished it gets new engines etc.
And at the earliest opportunity the future of the chinook fleet be decided when it goes to the CH-47F and wether we go down the route of all having folding rotors.
The Puma replacement can be deffered slightly but it should have Littoral capability.
