Boeing's 747 Freighters For 787 Program

Tue Apr 19, 2005 8:32 am

Does anyone know why Boeing is acquiring second hand 747s then heavily modifying them (possibly causing engineering issues to arise) as large cargo planes for the transport of 787 parts INSTEAD of leasing (dry or wet) some antonovs or C-5s or even (on the smaller side) their own C-17s?

Probably because they will need to use these aircraft throughout the production of the 787 which is a good 20 years at least.

Then why do they need to buy used ones (i think that's what they're doing)? Why not just produce new ones while their 747 line is open?

Because new ones are expensive and what would be the point in using a new one when it would get ripped apart straight away. If you look at an artists impression of what it will look like, you will notice that most of the top of the fuselage is going to be removed and the whole of the tail is going to be hinged.

Also, like Airbus, Boeing is probably going to move pieces that are larger than either the AN124 or C5 can accomodate....

Dimsum, my thought as well. Maybe too expensive a few used B744 as trade-ins for other Bs seem to be the solution.

I read last week that Boeing was not even going to operate the modified frieghters.. that it would go to bid, likely be DHL or some co. like that. Might have even read that here on A-net. K

I would like to know where you're going to hire any C-5s from...

In any case, I don't think even those aircraft have the cross section to carry a widebody fuselage.

New build or rebuild, the freighter conversion would still be a total rework of the airframe. At least with this strategy, Boieng takes some 747-400s off of the market.

I was pondering that for a while too, but can't they cut some kind of deal with USAF? Probably too unrealistic tho...

Oh I always thought the AN124 had more cargo space than the 747. (OR maybe they can get a couple of Myrias??)

Which is why I was puzzled. Aren't there other options aside from a total rework of an airframe, which can be quite costly and challenging (engineering-wise)?

Of course it does, but Boeing wants to modify the 744s to haul outsized pieces. These planes will look like Guppys/Belugas

This what it looks like. As you can see it's a lot bigger then your average 747  wink

If you lease a plane, the owner normally doesn't allow you to modify it radically  Wink

There is only one flying. Itmight take another 25 years before the second one is completed...  Silly

I took a photo of the ex China Airlines -400 that will become the first -400LCF in TPE the other day, it's not of good enough quality for airliners but it shows all the area's that will be cut off.

Do you think they have even considered the Airbus Belugas?  Silly

"Do you think they have even considered the Airbus Belugas?"

I'm sure the though crossed their mind... after all, until the Beluga entered service, Airbus used Boeings.

In addition to pride, I have a feeling the aircrafts range plays a big part here. The Beluga would probably have trouble operating trans-Pacific. I'm not sure if this modified 744 can go nonstop either, but I doubt it would need to refuel more than once.
