Old Airlift Vehicle Concept Made New

starexplorer writes "LiveScience is reporting on an early conceptual design of The Walrus the DOD's new planned 'very large airlift vehicle'." Could the concept of a 'war-balloon' really be gaining favor again?

    An airship that will look like the budget that funds it!

    I've been a huge fan of airships after reading up on them, but this thing will positively scream "TARGET" (not the chain store) to every radical nut with a shoulder launch missile. It will also move rather slowly.

    Perhaps a good choice for moving materiel between safe locations, but not something you'd fly over the Middle East any time soon.

      Also, this airship isn't built for hardiness at all. From what I can get from the article it will have many points of faliure. I don't see how a well placed photon torpedoes down a shaft can bring the whole death star^W^W Walrus down.

      Helium aircraft are a lot harder to shoot down than you might imagine. People are so used to party balloons that they seem to get the idea that helium aircraft failures would decompress as rapidly. Not even close - in addition to having more resilient skin, the volume rises proportional to the radii cubed, while the surface area proportional to the radii squared. I.e., there's a lot more gas to dissipate compared to the size of the hole. Then factor in that it's under lower pressure, and you get very favorable numbers. Small holes do very little to large airships.

      On the subject of missiles: I wonder how effective traditional homing mechanisms would be on a craft like this, with its potential for unusual engine positionings, visual profile, and probably an odd, disproportionate radar signature. Given its great size and slow speed, if they had effective countermeasures on it it might almost be worth painting it in Dazzle camouflage.

  2. Protection Methods??? by Nerd+Systems · · Score: 4, Insightful
    I read this story and it is very impressive how much tonnage that this device can carry... only one question comes to mind... how are they going to protect it?

    Based on the size of this warship, not to mention the slowness of it, am sure that it can't just easily outrun a fighter jet sent to destroy it, or be able to perform evasive manuevers...

    I can imagine that it will be escorted by a fighter division, not to mention have some high-tech anti-missle weapons and the like, yet I can see an air to air missle easily bypassing those protections and bringing down a TON of hardware with it... major catastrophe...

    Anyone have any ideas what sort of protection methods will be used to protect this massive warship, as well as if this will be used for strictly hardware transport, or troop transportation as well?

    We shall find out shortly it seems...

      The Goodyear blimps come home with bullet holes all of the time. An airship is a lot more difficult to bring down than you would think.

      As long as you don't coat it in rocket fuel of course... ;)

  3. Heavy lift aircraft don't usually do combat drops by Shivetya · · Score: 5, Insightful

    except from altitude and even then they are rarely if ever deployed in heavily contested areas. Most of the time they require large airstrips which in itself implies control over land and air of the region.

    What it does offer is many possiblities for not just military operations. If these things pan out in efficiency you can bet UPS and FED Ex would want them. Let alone the possibilities of flying cruise ships!

    FWIW, anything is a target for a terrorist, though preference is giving to things that don't shoot back.

  5. Stupid but not that stupid by A+nonymous+Coward · · Score: 4, Insightful

    Only a few comments so far, most of them about how easy it would be to shoot it down.

    But it won't be that easy. First of all, compartmentation. No doubt the bag will be at least dozens, if not hundreds, of individual compartments. Weight prevents anything equivalent to a ship with thousands of watertight compartments, but there will certainly be enough that bullets won't be much of a danger. The lifting gas won't be under pressure, so it won't start rips that widen the holes. And certainly the gas bag material will have anti-rip threading.

    It won't use hydrogen either, no one is that stupid. Helium is the lifting gas of choice.

    Shoulder fired missles are not a threat. This thing will fly above them. Their range is only a couple of miles. Full sized missles and full size AAA are a different matter, but again, compartmentation will help, and gas bags probably don't provide much of a radar signature to trigger fuzes, nor does the gas bag itself offer enough resistance to trigger most fuzes; they will probably fly right through and leave behind a few holes, trivial to patch.

    Which brings up damage control. I am sure the crew will be able to climb around inside and apply temporary patches.

    I think these heavy lift combat balloons are a silly idea. But they aren't nearly as silly as so many quick posts make out.

    When we have forest fires, we need to get tons of water in on top of the trees. Being able to load up from a lake and literally bring in 100 tons and slowly drop it in on top of them, would help a great deal with all the fires that we have in west. Right now, the approach is to use an old bomber and try and bring it in as fast as possible and get back to the fire asap. With this approach, we can simply lower a number of hoses and spray. Or we can just dump (you prefer being in closer though, and that will not happen with a large craft. Keeping 10 of these around the west, would allow us to quickly stop a fire and move the vehicle to the next fire. At the very least, it will allow for controlling the fire.

    Warship.

    Even the most modern, lumbering Aircraft Carrier is a big target for waiting submarines / strike aircraft so you protect it.

    You protect these things according to their strategic value. ie: The Aircraft carrier is strategically valuable so you give it a Frigate / Destroyer screen along with air-cover.

    In the case of the huge HTA cargo carrier, you likewise protect it with fighters, refuellers etc and because it can carry huge ammounts, perhaps give it it's own air to air missile system.

    Given it's size / lifting capability, perhaps these warships could also carry a Phallanx / Goalkeeper type system.

    For that matter, why not carry an F-22? This thing is supposed to lift 500 tons.

    It's not like it hasn't been tried before. I remember seeing film where a propeller driven biplane was launched and retrieved from the bottom of an airship. I also saw concept drawings of an airstrip atop a Zeppelin type craft. This is not a new idea.

    A fully loaded F-22 weighs about 40 tons, that means the craft could lift 12 planes.
