I would totally agree that it is unlikely that the C-27J will ever appear as an MPA in R.A.A.F colours, specifically as you say because of the risk of being the launch client and associated costs, however I would like to respectively make a couple of points.
The U.S Coast Guard successfully operates C-27J as MPAs
I raised this possibility because of the difficulty in quickly acquiring launch platforms to engage hostile vessels both surface and submarine at range from our shores and as suggested in my original post there are no quick fixes without cost or risk. The P8 Poseidon coupled with Triton gives a great capability, however there are only so many of them and MQ-9B SkyGuardian is not without its critics ( link below). At this stage, without any carrier aircraft, the ability to provide our Naval vessels with aircraft cover as well as our coast line remain vital. The range of the specific maritime patrol variant is not clear but with additional fuel tanks ,12 hour flight duration is possible and in addition the aircraft has air to air refuelling capability.
Finally like ASSAIL I don’t believe the R.A.A.F has lost faith in the airframe but in its ability to operate in contested space, ironically, an ability the NG upgrade may fix. i probably should have put a link to the upgrade in the R.A.A.F thread suggesting it could return to its original role, however I also see advantages in having an expanded Hercules fleet in the long term. I would also love to see these orphans properly employed not join the many other costly defence acquisitions cast to the scrap heap .
