to shoot down a drone?

How high do they fly, how fast? What's the best anti-drone weapon? Will a jump in anti-drone tech make them suddenly obsolete?

The MQ1 Predator drone flight at a maximum of 7629m or 25000ft at a speed of 217km/h (135mph). A roughly standard ground-air missile is the FIM92 Stinger which weights 10kg (22lbs) and has a range of 8km (26000 ft) and can speed at 700m/s (2520km/h, 1600mph). If you have them, then the predator is a sitting duck. I suppose the difficulty is spotting them, present models are rather silent.

Operating characteristics of the next generation of drones are classified but it appears they will have an operating ceiling of 70,000 feet, stealthed, and carry a fighter/bomber-equivalent weapon payload.

There's no technical reason they can't meet those design specifications and there's good operational reasons for the Air Force, etc., to issue them.  So I expect a "jump" in capability within the next 4 years.

Of course, still the faster they go the harder it is for them to observe the territory, which is, at least for now the main point. They may be the substitute of bombers and cruise missils.

Just as happened with the "aeroplanes" in WW One it seems the drones are being split between intelligence/surveillance craft and fighter/interdiction craft.  The next step is high-payload bombers, and I'll bet someone, somewhere, is already working on them.

With the US B-52 fleet of heavy bombers becoming overworked and tired I that "somewhere" is "here."

Very hard to shoot these things down because it's almost impossible to detect them and air-to-air missiles aren't designed to operate at 70,000 feet.  

Flight speed is anywhere from "loiter" to over Mach 5.  

A reliable anti-drone weapon system hasn't been specified, designed, tested, and deployed.  

Given the low cost of drones, to purchase and to operate, versus other "force projection" weapon systems I doubt they will become obsolete in our lifetime.

I don't think the Mach 5 are operative for now. Mach 5 as a lot of constraints, even if you can save the pilot.

Mach 5 is conservatively 6000km/h or 3750mph.

Fighter aircraft technology has, for decades, been design-limited to the low-tech specifications of a human.  The airframes, etc., can withstand 12 g maneuvers.  Do that to a pilot and you've got strawberry jam in the cockpit.

Also the reaction times and experience of a human pilot are (1) bad compared to cybernetic decision speed and (2) 1:1, with a cybernetic, expert system, in control every "pilot" would have the ability and experience of a Top-Gun pilot instructor.  No more steep learning curve for new pilots: the operator hits the "evade" or "attack" button and Bob's your uncle.

Given the fuel requirements for Mach 5+ I think that would be the top speed, used during transition from base to patrol/combat area.  In those areas "loiter" would be the normal flight speed, only going higher during actual combat, as a predictive guess.

There's no reason to go fast at all during that transition from base to patrol area ; actually you want maximum fuel economy for that part.

And without the need to maintain a pilot awake in the cockpit, nothing prevents, say, a 30 hours flight from US to anywhere in the world at best fuel economy speed...

Given that they communicate with their handlers with wireless communication I think the relevant question is how hard it is to hack and/or scramble the communication. From the diary it appears it is not that hard.

So rather then shooting down hostile drones, seize them in midair and send them back.

Tapping their communications is significantly different from taking them over.

Still, the fact that they didn't slap a standard commercial-grade crypto the things boggles the mind.

I was thinking more about the virus, though I admit that was not very clear.

Protecting a communications channel from being hacked is a simple process IF you implement hardware security and adequate software handshaking protocols, e.g., 'offset' the data within the binary word by some number of bits and AND off the NULL ones.

(Naturally you'll have to know assembler language to do this ... which you young uns generally don't :-p)

(lol)

Won't (always) work if your hacker has identical hardware and knows your algorithms.

Absolute security is a Very Hard Problem. Real security is always an affordable trade-off between absolute security and cash.

And didja know that some IBM (and likely other) mainframes include built-in encryption hardware?

The hardware can be protected if they are kept physically safe and the schematics and assembly procedures are burned after the production run.

There's all kinds of games you can play with the software: data binary word length, binary word placement, algorithm cycling, synch/desynch on the transmissions, burst/stream transmissions, wide band/narrow band, etc. etc. etc.  

I wouldn't trust any generally available encryption programs.  If they are a usual part of the IBM software then they can be cracked if enough resources are thrown at the problem.  

Despite everything, above, One Time Pads are the only way to go if you want to ensure security.

They'd have to steal them, copy them and reinsert them into your logistics before you notice they're gone.

Possible, in theory, but if the other guys can pull that stunt then your organisation is either so hopelessly compromised or crushingly incompetent that somebody stealing your bombs mid-flight is not the greatest of your concerns.

Keeping stuff physically safe is pretty hard in a combat environment. See how the Soviets got hold of the Sidewinder technology...

Meteor Scatter Telemetry is harder to intercept, works even if satcoms get busted, and is way way cheaper.

Obviously you use an anti-drone drone. Question is, who in the long run can make them cheapest?

No one questions jets can shoot down unarmed surveillance drones operating in the jet's flight parameters when using an AtA missile operating within it's design specifications.

Georgia operates 10 year old Hermes 450 drones

with a primary mission of reconnaissance, surveillance and communications relay

The craft has an 18,000 foot ceiling and has a 52 horsepower Wankel, internal combustion, engine.

Hardly front-line, high-tech, equipment.
