Considering that it was developed with private money on a shoe string, the program has had some fairly remarkable accomplishments:

• Achieving a cruise speed in level flight of 253 kts, a record.
• Doing so while maintaining the low speed and hover performance of a conventional helicopter. (as compared to the performance of the V-22 in those areas, which is just pitiful)
• Doing so at noise and vibration levels equal to or lower than current helicopters.

Sikorsky will not be moving onto developing the S-97 light attack/scout helo.
