The U.S. Navy and the U.S. Air Force are in the earliest stages of creating the requirements for their next generation of fighters but development of the engines that will power those aircraft are already well underway — and provide hints on what American sixth-generation aircraft will be able to do.
One thing is already clear, both aircraft will be fast, long range and extremely efficient.
Da notare che l'artwork del velivolo di Lockheed Martin era apparso, poco più di un paio di anni fa, su un calendario donato ai giornalisti ..... come a suo tempo riferito dal blog 'The DEW Line' di 'Flight International' ..... http://www.flightglobal.com/blogs/the-d ... als-conce/ .
The US Air Force is moving ahead with plans to develop a sixth-generation fighter jet engine based on technological improvements achieved through an ongoing effort to produce a power plant for a future long-range bomber.
In a request for information released 19 August, the air force said it plans to release a final request for proposals for the adaptive engine transfer programme (AETP) in the first quarter of fiscal year 2015, “notionally December 2014.”
