Sikorsky has placed a $15 million price tag on its S97 Raider, as it attempts to convince the US Army that the aircraft is a low-risk replacement for the Kiowa Warrior.

The Pentagon has set a target range of $13 million to $15 million per aircraft for the AAS project.
For reference, a AH-64 Apache costs about three times as much. After many hundreds have been produced, for decades.
Real price, of course, depends on costs included, excluded, spare parts, training etc. etc. Still for a brand new innovative design $15 million seems on the optimistic side in my opinion.
