From what I understand, the contracted all up propulsion system includes the TV system and the nozzle. This is how engines are delivered by the OEM as the unique TV nozzles are very much an integral part of the design that P&W furnished to the airframe prime. So yes, the weight estimate (no idea where RAND got it from though) would include it. Both these engines also have IR supression requirements that their legacy counterparts in the teens did not have so those also add to the weight but are necessary given performance requirements sought by the ATF and JSF programs.
I remember us having this conversation earlier. Refer to this forum/thread for additional information. I had earlier provided the picture referenced in the thread (link to which is broken).
