For Mk3 F2F read "Mk3 Reversion"
I can't find the link, but it's public knowledge that F2F is cancelled and that they are retrograding them back in time to the Mk2 Mod standard. The Topdeck cockpit is dead, for now....
So: More Heavy Lift for Green Army; no increase in HL for SF who will continue to be supported by NEP aircraft (ouch).
PS - They did have a nice coherent plan for Chinook common cockpits in the future. They DID, but this has gone AWOL with F2F being cancelled.
