From the tip as seen at Freeper and thanks to the English Daily Mail herewith the successor as proposed to the American ground attack warplane the A-10.
"The 'Machete' that could replace the A-10 Warthog: Radical lightweight metal foam attack plane with a PROPELLER"
* "Machete is a concept for a new light-weight attack plane for the US Air Force"
* "Designed with a metal foam instead of the traditional armor"
* "Will be single engine, single seat planes and offered in 2 variants"
* "Other models for air-to-air combat and advanced training could also be released"
A pusher with the propeller in the rear. At this exact moment only a concept and a drawing on a piece of paper? AND possibly will have an aerial combat capability too? A jet version also under consideration.
Perhaps where F-35 Lightning cannot the Machete can?
