AV-8B Harrier II++ anyone?
Is there an echo in here ?!
Talking of lift fans and history, might be time to dust off and modernise some of the P-1216 ideas.
I recall one or two very sexy looking proposals, using a 3-post twin boom layout, big ( reheated ? ) aft nozzle a la F-35, and variable shutters for forward lift thrust instead of draggy front nozzles.
Even forward swept wings were considered, 'all' that would need adding to the mix is stealth - or is it worth the cost; financial, R&D time and performance ?
