What Is The Next Generation Strategic Airlifter?

Are there any plans to replace humongous strategic airlifters, namely the C5? I know the C5s are going through a re-engine program and getting modern avionics which will most likely add to the service life of the fleet. But regardless of all the updates and bells and whistles, these planes are some of the oldest in the USAF, and the Pentagon must have some kind of plan in place for a replacement. I personally believe that a tactical airlifter, ala the C17, can't be a suitable replacement for a strategic transport like the C5.
And does Russia have any plans to replace their fleet of AN124s?

Oh the USAF has a plan: take the money and buy fighters instead. They'd be like a kid sent to the corner store for milk and bread but coming back with cookies and soda.

The C-17 really straddles the gap between tactical and strategic. Eventually a C-5 replacement will be needed, but that will happen whenever the USAF gets sick of paying to fly them, and that could be a while.

My two cents, my opinion. It won't be ordered tomorrow but when a new gen airlifter is needed I am betting it will be something like this.

The USAF is working on a airship:

This one is a scaled model of what they want to build, but the end goal is that the full sized one will carry 66 tons of cargo. Very promising technology involved here, which could revolutionize the strategic airlift force.

The C-5 and the AN-124 will be replaced only after their dwindling numbers become so small that the various military missions cannot be filled.

Look for an increase in surface transportation rather than airlift, at a higher cost eventually. The cost of not having the airlift capacity will also make surface transportation more expensive.

When will this expense point be reached? - my guess is that current aircraft will be used through at least 2025.

After that - who knows. Slow airships are a definite possibility.

I'm not sure the US or Russia will be the next nation to build a strategic airlift aircraft. The incentive and high cost factor may come from the commercial community - and the aircraft might be built by being funded by a group of large multi-companies.

If such an aircraft were built by commercial interests - I doubt the US military would be able to persuade the US Congress that developing their own aircraft vs buying an already flying design was cost effective.

Explain why airships are a better solution now than 20 or 40 years ago?

The Japanese have a system of sustained low-rate production for some aircraft. Expensive I'm sure, but suppose the C-5 was still in production, wouldn't building one-two new aircraft a year be a good solution?

We'd have far too many C-5s even at 1/year. Granted if you go kaizen on the line, perhaps you'd be scrapping the cruddy old ones rather then throwing money at them.

Incidentally the E-2 and C-130 have been in production forever.

I can't see airships that can carry just 65 tons being a replacement for a C5/An-124 sized jet. I can think of at least 3 good reasons straight away. Firstly these jets can already carry over 100 tons of cargo, secondly they are much faster and finally they are much less likely to be affected by poor weather conditions.

I think there is a place for airships in the world of heavy lift and outsized cargo, particularly in the civilian world where speed may not be a prime consideration and where the potentially lower operating costs of an airship over a jet are desirable.

Other plus points would be that an airship doesn't need a runway and may have the potential to land on water and/or gain access to remote areas thereby removing the need for potentially problematic overland transportation of cargo from an airfield.

There is little to no promising technology here. That specific project is being built by a company that doesn't have the greatest reputation in the LTA industry to begin with. Ultimately, this project, much like the Blue Devil and LEMV, are nothing more than corporate welfare for DOD contractors.

The airship will never be a tactical or strategic device for anyone.

How would you define a strategic vs tactical airlifter? From wikipedia: "Strategic airlift is the use of cargo aircraft to transport materiel, weaponry, or personnel over long distances. Typically, this involves airlifting the required items between two airbases which are not in the same vicinity. This allows commanders to bring items into a combat theater from a point on the other side of the planet, if necessary. Aircraft which perform this role are considered strategic airlifters. This contrasts with tactical airlifters, such as the C-130 Hercules and Transall C-160, which can normally only move supplies within a given theater of operations."

The eight examples listed include the C-17 and several aircraft the C-17 is larger than, such as the IL-76 and C-141.

Why?

I don't have an answer to this question but what specific pieces of cargo can only be carried by the C-5 that cannot be carried by the C-17? As far I know, the answer is the Mk V Seal Boat, an Army bridge layer vehicle, and some space/satellite cargo that is carried by modified C-5Cs. There might be a few more, maybe galaxy5007 and topboom have an answer?

So, based on the few pieces of equipment that only a C-5 can carry, does that justify the cost of a complete C-5 replacement? Or should we keep 10-20 C-5Ms around for the next 50-100 years for the occassional mission that specifically requires a C-5?

at the rate we use to do staging of equipment (months), what's wrong with a lighter than air delivery of oversized stuff.. besides we'll have the F-35 flying protection.

BTW, Kuwait has asked for another C-17, so extend the line another 3 months..

A main battle tank comes to mind, but then we sent most of those to the Middle East in 1991 and 2001 via RORO ship, as I recall.



I echo those who believe the C-5M will soldier on for the next couple of decades. Now that the USAF is getting the KC-46, that will provide a fair bit of new lift for standard palletized stuff and assuming we see the 777 Freighter replace the KC-10A down the road, that would be even more.

Huh? The C-17 can carry an Abrams MBT.

And, yes, it is enormously more economical to carry large vehicles via ship than via strategic airlift. You only use something like the C-17 or C-5 to carry large vehicles in a special situation.

My guess is that it will be a BWB aircraft in about 25-30 years.

Would it be feasible to build a stretched and re-winged C-17 to replace the C-5?

My guess is also a BWB, if not suited for passengers, it will be a great cargo hauler, wide decks, not very long though. 30% more efficient than a tube+wings?

FYI, the C-17 can only carry a M1 Abrams MBT with a special waiver. The operational weight limit for loading tracked vehicles across the C-17's ramp is 130,000 lbs. A waiver was granted to allow loading of an M1 Abrams tank weighing up to 135,000 lbs. Boeing and the C-17 project office conducted studies and trials which showed that the ramp would not be adversely affected by a M1 Abrams.

Likewise, the C-5 also operates with a operational waiver as the operational weight limit for loading tracked vehicles across the C-5's ramps is 129,000 lbs.

OK. I was confused by the way you worded it - I read it that Kuwait was getting more C-17s, when they don't have any. A "fleet" of one seems a little odd.
