By running around to multiple sources, it seems that what we know so far is the Army wants is (I relaize some of this may have been stated here earlier):
Maximum speed: at least 180 kt with a hoped for dash of 200 knots, a single 3,000-shp GE T901, 40 ft diameter rotor, max gross weight: 14,000 lb., the ability to carry four-eight (I'm not sure of the number) Hellfire or JAGM or UAVs with the ability to control same, hot and high HOGE performance, a specified (maybe someone knows the precise numbers) range and endurance.
The agility requirement is greater than that wanted for the Armed Aerial Scout program, which was the program that the larger S-97 Raider was designed around, but the speed requirement is lower (note that Sikorsky acknowledged S-97 never would have been capable of reaching its design speed but that wouldn't be as big a problem with the lower FARA requirement). There is no requirement for an internal cabin in FARA as there was in AAS, nor is there a self-deployment requirement as there is in FLRAA.
Possibly someone else here can fill in some of the other requirements. So far no one has addressed the issue that aeronautical engineers and the Program Manager himself has have said that with existing technology a vehicle that meets all theF ARA requirements can't be built.
