Hyd3failure,
Sorry, but IPR is what counts here, you try getting the source codes for the C-130J out of LMAS, or for that matter the many other avionic OEM's who supply black boxes to aircraft like the J, this is where DARA came unstuck when they tried to get Sealand set up as a centre of excellence for avionic overhaul.
As to simulation, in the case of the J LMAS subcontracted Reflectone to provide the simulation service, MOD didn't get a look in.
