Artist rendering of a McDonnell-Douglas WIG in USAF colors (note SAC shield) firing a cruise missile from its retractable launch tubes. Probably a good way to upset the Navy.

This WIG looks like it can also fly at altitude, like a Bartini VVA-14. (Original painting by Mike Machat for McDonnell Douglas Corporation. Courtesy Mike Machat)

Do you have a date for this concept circle-5?

Sorry for ignorant question but why does the USAF have not implemented transport WIG as a mean to storm beaches,

...Because the Air Farce wouldn't be the branch to develop and implement an aircraft for such a purpose. The Navy and Marine Corps would be the most likely branch to consider using such a vehicle, with the Aaaarmy coming in second and most likely using whatever the Navy put into service. That being said, the closest thing the US armed services came to implementing anything WIG was the Sea Spectre, a remarkable cross-breeding between an F-117 and a large PT Boat whose stealthy nature of mission wound up being its reason for failure, as the Navy had extreme difficulties getting any of its flag officers to assume command voluntarily; for some whackjob reason, they felt using such stealth technology combined with stand-off-and-shoot(*) in high seas combat was "cowardly" and "dishonorable". Personally, I'd have given my remaining good leg for the honor of commanding such a vessel. And my left nut for the privilege to actually use its might in combat against our enemies.

(*) If being able to strike from a distance without detection was a sin, try telling that to battlecruisers with 16" guns, painted in camouflage.
I'm confused? Are you referring to the Navy's MKIII Sea Spectre Patrol Boat? IINM, these had a fairly long service life(mid 70's to late 90's) but were not particularly stealthy so I don't understand the F-117 reference?
I think he was meaning the "Sea Shadow" no the spectre...

Ah, that makes a little more sense, though Sea Shadow is only a technology demonstrator incapable of deploying weapons(and of course, not a WIG)...

Well... it IS kind of "WIG-ish" looking I suppose :)

Hi

If you follow the link given below you will find a 3 volume report about wingship investigation in the U.S. They are quite large and cover every aspect: missions, aerodynamics, propulsion and so on.

Also they report (in volume 3) short descriptions of proposals for large WIGs by Lockheed, McDonnell Douglas, Northrop  and Aerocon (with technical data and line drawings).

OR... we can try to clean them up a bit to make them a little more user friendly... Don't you think it's a lot better this way?

Nice... but if it's the Aerocon design, why does the blueprint say "Northrop"?!?

As I suspected, this is not the Aerocon proposal, but a USAF proposal based on a Northrop design (ARPA Wingship Program Parametric Study - Preliminary Results -
Northrop Jul. 1993):

Quote
The two WIG concepts evaluated in this study are the DASH-1.6, 5000-ton Wingship created by Aerocon Incorporated, and a 3000-ton variant developed by the Air Force ASC/XREDT of a Northrop 800-ton concept. Details on these two concepts, as provided by their developers (References 2 and 3), are presented below.

Quote
The inboard profile drawing, shown earlier in Figure 2.1-4, for the Northrop 800-ton WIG depicts a nose visor door and rear port side doors for loading and unloading. No dimensions are given for these doors. It is assumed that the nose visor door will open completely to provide straight-in loading/unloading access to the full 28.4 ft wide and total 33+ ft high (14 ft upper, 19 ft lower, plus upper floor thickness) cargo compartment. The two rear loading doors appear to give full height access; the total width of the two doors appears to be about 60-percent greater than the height.
No ramps or other equipment are shown in the drawings for loading and unloading. Integral ramps, similar to those on the Aerocon concept, could be developed as a future design refinement.

Old WIG topic split.

Please use this new topic for WIG studies from Lockheed, Northrop, Aerocon, Bell, and so forth (NOT the Boeing Pelican, which already has its own topic).

There will be separate topics for Russian WIGs and small-size, general aviation type WIGs.

Hi,


here is many Ekranoplanes designs for small designers;
