General Electric CT7-8E6
Like the Grippen, built around an American engine.
The AW249 uses a variant of the same one used by the Apache
"The AH-64 is powered by two
General Electric T700 turboshaft engines with high-mounted exhausts on either side of the fuselage. Various models of engines have been used on the Apache; those in British service use engines from
Rolls-Royce. In 2004,
General Electric Aviation began producing more powerful T700-GE-701D engines, rated at 2,000 shp (1,500 kW) for AH-64Ds."

"The T700-GE-700 was followed by improved and uprated Army engine variants for the
UH-60 Black Hawk and the
AH-64 Apache helicopters, as well as marinized naval engine variants for the
SH-60 Seahawk derivative of the Black Hawk, the
SH-2G Seasprite, and the
Bell AH-1W Supercobra. T700s are also used on Italian and commercial variants of the
AgustaWestland EH101/AW101 helicopter, and Italian variants of the
NHIndustries NH90 helicopter. These are all twin-engine machines, except for the three-engined EH101.
"The commercial version of the T700 is the "CT7", with the engine used on the
Bell 214ST (an enlarged version of the Huey), commercial Black Hawks, and the
Sikorsky S-92 derivative of the Black Hawk, all of which are twin-engine helicopters."

....
So the choices are an American helicopter with an American engine, an Italian helicopter with an American engine and other systems, or an American helicopter with a British engine.
You could try your luck with an Italian helicopter with American systems and a British engine but you might have to wait awhile for the Ajax committee to get back to you. I understand they are presently engaged.
