Yes, regardless of how the J is or isn't performing now, it's delayed entry to service alone was worthy of BAE at its best and attracted penalty payments equivalent to two of the 25 aircraft.
And in addition to the late arrival there was a raft of problems (many detailed on this board) associated with the new AMLCDs and digital avionics, the stregth of the cargo handling system, the propensity of those using the para doors to hit the aircraft on departure, etc. etc. There were issues about range without tanks, crew duty times and a real concern about the two-crew flight deck. USMC Pruners pointed to the unsuitability of the new props for operation from graded coral airstrips, and problems with the refuelling pods. In short, there was a time when the C-130J looked like a better example of poor procurement and manufacturer incompetence than any British type.
Now most of it's history, perhaps someone with a better memory will post a more definitive, better explained list?
