    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.

    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...

      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.

    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.

    • 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.

      But the cargo inside the ship will indeed be solid and will offer enough resistance!

    • Anti-aircraft missiles are not intended to hit their targets, that is too difficult. They explode in proximity to the target and bring it down with shrapnel.
      As such, they would be just as deadly for an airship, filling it with thousands of little and not so little holes.

    • According to DARPA's press release, "the Walrus aircraft will be a heavier-than-air vehicle and will generate lift through a combination of aerodynamics, thrust vectoring and gas buoyancy generation and management."

      You and everyone else who suggested comparmentation as a reason why it won't be so vulnerable probably didn't RTFA. Depending on how much of the lift really is the aerodynamics, a single deflated compartment may very well destroy its lifting capacity.

      Regardless, all of us are idiots for think

    • Shoulder fired missles are not a threat. This thing will fly above them. Their range is only a couple of miles.

      This is an airlift vehicle. It is ment to move large payloads. Generally, that means it's probably going to be landing in the hostile country to drop off those paloads. If one or more hostile folks with shoulder launched missles sneak up near the landing field, it could mean a very rough landing.

      • Shoulder launch missiles are generally either unguided or heat seeking. A missile hitting the gas bag would hole it - probably minimal damage, they leak slowly; a missile hitting the hottest part of the ship - one of its lift/propulsion motors - would sort out the motor and probably put a fair few shrapnel holes in the gas bag - neither will quickly down the aircraft.

One of the biggest problems was that the vehicle was so big, it would hardly fit onto the runways at LAX. Try having those things land regulary at any busy airport and you are going to have major logistical problems. Also, I worked on a similar concept for a now extinct company in Germany called CargoLifter. There airship was called the CL160, which was actually lighter than air (didn't need aerodynamic lift) and was the length of roughly 3 American football feilds in length. It could carry 160 tons of cargo from destination to destination ...eliminating the need to build things in small enough pieces to be carried on the highway.
