US Pentagon Plans For a Spy Blimp
nloop writes "The Pentagon is intending to develop a new spy ship — a dirigible. At 65,000 feet it would provide a 10 year, solar power based, unblinkingly intricate and continuous view of the surface via radar surveillance. Because of its altitude it would be safe from surface-to-air missiles and most aircraft. A 1/3-scale prototype, now being designed, is 'known as ISIS, for Integrated Sensor Is the Structure, because the radar system will be built into the structure of the ship. ... 'If successful, the dirigible... could pave the way for a fleet of spy airships, military officials said.'"
Because of its altitude it would be safe from surface-to-air missiles
The U2 went for this, and it didn't work for long. Though I'm guessing that for what is essentially a balloon with a sensor package, it's radar signature will be pretty low to start with, and extra stealth technology notwithstanding.
Don't worry, after the couple of unfortunate incidents, the surplus will be sold off at a substantial discount to local law enforcement agencies who wish to better Secure the Homeland(tm).
and safe from most fighter planes.
Hmmm. most...It's almost as if they thought that there might be some advanced planes...almost as if they had done some research on possible opponents...almost as if experts in the field are as smart as a Slashdot reader.
Just use a laser

It's amazing what 65,000 feet of atmosphere will do to your nice laser. Plus the joy of keeping it focused on one place to allow the heat to build up sufficiently.

That First Generation War stuff isn't the only game in town...
Observation doesn't necessarily require being directly over enemy territory. Such airships would be excellent for covering borders and providing 25/7 situational awareness over areas of Iraq and Afghanistan. They can also observe large marine areas, which is why blimps never totally went out of US service. They aren't sexy, and the general public keeps confusing them with the Hindenburg, but they are useful pieces of gear. UAV don't have near the loiter time of a blimp/airship, but they can plug gaps when the blimp is out of service. Working together they could make for excellent surveillance/interdiction systems.

Hmm. Large gas-filled object, presumably with a not overly-thick skin to keep the weight down. Ground based laser of sufficient power to pop a hole in the giant balloon.
Yeah, this is gonna work real well.
You are aware that an airship's lift cells are pressurized to barely over atmospheric pressure, don't you? That the lift comes from the volume of gas being less dense than the atmosphere, not from pressure? Take a plastic shopping bag, shake it open, then squeeze the open end closed with your hand. Now poke the inflated bag with a needle. See how violently the bag ruptures? Oh, wait -- it doesn't do that at all; you just get a leak.
Go back and read how hard it was for Allied fighter pilots in WWI to take down German dirigibles and observation balloons; because they were filled with hydrogen, they would have to shoot holes in the balloon, then fly back and fire tracers or incendiary bullets through the plume of escaping hydrogen gas coming out the holes they'd shot. But airships lifted by helium don't have that weakness, so the problem would be limited to patching holes.
It's amazing how trivial those problems are compared to protecting a blimp at 65,000'.
From http://en.wikipedia.org/wiki/Airborne_Laser:
"If the ABL achieves its design goals, it could destroy liquid-fueled ICBMs up to 600 km away. Tougher solid-fueled ICBM destruction range would likely be limited to 300 km"
65,000' is just a hair under 20 kilometers. That's beans compared to what the ABL is supposed to be able to do against a smaller, much faster moving target, from a mobile platform. You might need a stronger laser than the ABL carries, but as I said before, most blimps aren't particularily tough.
You are completely missing the about about this things use. In all modern warfare contexts the US has total air superiority. If a war arises where that is not the case, the US makes sure it gains air superiority very quickly.
Once you have air superiority and have bombed shit out of everything that could launch a missile large enough to reach it this thing is perfect for spotting hostile forces on the ground. Most of the people we now fight against are so out gunned in the skys they resort to terrorist and guerilla actions. This thing can be kept flying for very long periods, very cheaply. It also has the advantage of being able to hover. This means when it sees a target, it can remain stationary above it and maintain a visual for long periods.
The current solution is to use spy drones but they are vulnerable to small arms fire form the ground, need fuel, and have to fly in circles to maintain a visual on a fix position. This circling vastly reduces the effectiveness of the drones in urban environment with tall buildings.
I dont read
You're assuming this will be used against foreign countries.
There's no reason it can't be used domestically as well.
Or entirely.
Nothing to see here citizen, move along.
