Tak, bo pierwotnie te silniki były zamontowane w dwóch prototypach Northrop YA-9 (a wcześniej chyba w Convair YF-102) czyli konkurencie późniejszego A-10 Warthog II
. Prototypy płatowców oddano do muzeum, a silniki latały na tym ulepie w ramach programu: "Quiet Short-haul Research Aircraft (QSRA)".
The two YA-9 prototypes were subsequently relegated to NASA for continued flight testing before being quickly retired. When retired, the YA-9s' custom-built engines were removed and were later mated to a C-8 Buffalo airframe as part of the NASA-Boeing joint Quiet Short-haul Research Aircraft (QSRA) study into a quiet short-haul commercial aircraft.
