Not bashing. To refresh:
The
Defense Department laid out a slew of mechanical issues found during initial testing that include: “airspeed indication anomalies, low reliability of main rotor gearbox, hot gas impingement on aircraft structures, tail boom and tail rotor structural problems, overheating of main rotor dampers, fuel system anomalies, high temperatures in the #2 engine bay, and hot gas ingestion by the #2 engine, which could reduce available power.”
Add to this the unit cost is 3x the original and the original 2015 IOC has moved to beyond 2021 you get a picture of a lack of the program/design competence required to meet current commitments and capture future programs.
