C-17 restart
 
More teasing of a C-17 restart.

Sometimes it becomes very difficult or cost ineffective to improve on such a proven design.

Been through this before. All the jigs and productions facilities for the C-17 are gone, even the entire production site is gone. Many of the parts - such as even the engines - are out of production and no longer available.

With the redesign needed to introduce modern materials, and meet new requirements, restarting production could take longer and be more expensive than a new programme - though I am sure Boeing would love it.

Yes Orac. No the production site is not gone, drive by it twice a week to/from work. The building is still there, leased out to others. There are other locations that can host building and have the skilled labor available. The same challenges to build a NG C17 were likely present to build the classic model, and imagine the naysayers were present then as well.

Just watch and wait like the rest of us.

Surely the whole point (and benefit) would be not to do any re-design or introduce new materials...?
Its quite a sensible thing to consider, it would still be a huge time saving, even with creating a new production facility, new tooling, and putting new engines and kit back into production....compared to a new clean sheet design that would add a decade plus to getting to first flight off the line.

Please, can we Brits have some? Pretty please.

We can't afford any.......

How many times did MD say if you want to keep C-17 production open you need to buy more NOW? I saw the MD-11 tooling/fixtures piled up to be cut up for scrap. Don't know what happened to C-17 tooling as that was on a different site across the airport.

Pratt & Whitney ceased production of the F117-PW-100 engine, which powers the C-17 when the manufacturing line in Middletown, Connecticut, shut down after delivering the final unit in January 2016.

The current support programme for the engines runs till 2027, this will be renewed but, inevitably, costs will increase year by year and the number of spare engines will shrink.

Which is why, quoting from the article above, the C-17 proposed isn't the same as the current models, any more than the 747-8 is the same as the original 747.

Quote:

It is unclear what it might cost to get the C-17 line restarted and what the unit price of these new-production aircraft would be in the end.

There are various factors at play, including whether Boeing retains any relevant tooling, the knowledge base of its current workforce, the state of third-party supply chains, and the availability of physical space to build the airplanes.

Back in 2019, the company sold off the facilities in Long Beach, California, where it built the original run of Globemaster IIIs.

More than a decade ago, the RAND Corporation did conduct a detailed, independent analysis that explored options for resuming production of the baseline C-17A, a new C-17B, and a significantly revised “fuel efficient” C-17FE derivative.

The C-17B was “a variant Boeing has proposed that adds centerline landing gear, a tire deflation/inflation system, higher-thrust engines, advanced flaps, and an advanced situational awareness and countermeasures system,” according to RAND’s report.

The C-17FE derivative “would have a narrower fuselage, up-rated engines, a double-element flap system, winglets, a longer loading ramp, a shorter cargo door, and a modified horizontal tail.”

If the need is big enough , anything is possible.

True, but if there is an urgent need the logical solution is to bring forward production of the NGAL.

Probably wouldn't be any tougher a challenge for Boeing than making a 767-based tanker!

Hey Vzlet, you may not have realized, but that is funny!

The engineering development is not the biggest cost of putting a new aircraft into production - yes, it's expensive and important, but it's setting up production - supply chain, tooling, manufacturing facilities, etc. - that adds up to the big bucks. Plus, depending on how good the MacDac record keeping is, there is going to be a non-trivial amount of engineering development in just putting the original C-17 back into production.
Given that most if not all of the C-17 tooling is gone and would need to be re-created (as well as the supply chain) - and the simple fact that the engines and avionics are obsolete and out-of-production and would need to be completely redone - it would cost nearly as much to put the 1980's tech C-17 back into production as it would to simply do a clean sheet design using current technology, and the result would be a much better aircraft.
If the idea is to do a 2020 tech C-17, then do that, but don't simply put a 40+ year old design back into production.
The NGAL would be good too, but it would take much longer than a simpler C-17 style replacement, and cost mountains of cash more.

Yeah that went well.
