The military branch will also allocate part of the requested funds to the production of engineering drawings for the aircraftâs âclean-sheet design,â Donovan said in a Tuesday interview.
He noted that Northropâs work on the bomber is âgenerally on trackâ and âwithin the windows of expected progress that weâve expected at this point,â the report added.
The Air Force selected Northrop in October 2015 for the potential $80 billion contract to build at least 100 B-21 units.
