A TWZ article on the NGAL for the USAF. Replacing the C-5 and C-17 with a single aircraft, difficult if both capacity
and tactical performance are required. IMO a restart of the C-17 (enhanced) and a NGAL would be better, especially if a modified C-17 could offer better tactical performance eliminating the need for faster C130 replacement.
Plans for a Next Generation Airlift platform, or NGAL, targeted for entry into service in the 2040s, are starting to coalesce.

Problem no.1
starting in the mid-2040s
So the timeline doesn’t work for that.
Problem no.2
Like with the F47 program the
Raison d'être, boils down to the amount of resources invested in a C17R would be equivalent to that of a brand new aircraft. The C17 is a 30 year old design. The engines it uses the F117 (PW2000) series are 40 years old they were designed for the 757 have been out of production since about 2016. All the components are by now obsolete or out of production. The original factory is long gone. The documentation would likely have to be redone. The whole thing would have to be reworked from scratch. Additionally the aircraft would need a massive overhaul in mission systems and well at it might as well bring in 3 decades of new materials and aviation design.
C17 still have decades of service life it could potentially be reengined. Those are a lot easier than restarting a line. It’s the same thing that happened with the F22 Raptor the cost to restart and the cost to buy new are just so close might as well start over.
As to C130… C130 is fine for many special missions it’s still in production and new variants are emerging however. Its intended role for rapid deployment forces is no longer viable. Airborne forces can still use it but medium weight forces like the Stryker and Marines infantry are generally out. The latest Stryker and Marine ACV are pushing 34 tons and the size difference between older generation of vehicles like the M113 and modern ones is striking. It’s why the Japanese moved up to the Kawasaki C2 and the Europeans have the A400M.
C130J can move some armored vehicles but those are things like the JLTV and it’s a tight squeeze. The KC390 is interesting and has been offered to the USAF but it’s too close in payload to the C130J30 so procurement makes no sense.
C17 is a wonderful platform but when you move up that much the burden to do the jobs of the C130 would be destructive. There needs to be a medium. It’s long overdue for one. The thing that has kept the C130J alive was that it was in production. The British stepped in at the C130H was closing and asked for more C130s well the A400M was in the distant future. So LM gave them what they wanted and the USAF joined in. Similar situation to the E7A.
