| Interesting, that this form-factor was popularized by DIY builders. First one was dutch-built, sponsored by Red Bull after prototyping stage, to film Verstappen's full F1 lap (so semi-DIY, so to say), but then record was taken back and forth between two DIY builders — Ben Biggs in Australia and Luke Maximo and his father Latest record by Ben Biggs was 626kph (389mph).
Latest record by Luke Maximo was 655kph (408mph). |

| Not even close to the manhole cover speed record. |
| |
| ▲ | LorenDB an hour ago | parent [-] | | For those unaware: https://en.wikipedia.org/wiki/Operation_Plumbbob Most people agree that the manhole cover would have been vaporized during its atmospheric ascent portion of flight, but I still like to believe that somewhere out there in the void, a small blob of molten steel that survived the atmosphere is drifting in solar orbit. | | |

| There are amateurs chasing the speed record using similar designs too:
https://www.youtube.com/results?search_query=world%27s%20fas... Unit cost for a lot of these seems to be under ~$5K USD, not counting the value of engineering time. How do you counter a swarm of these things coming from all directions? This kind of weapon has interesting consequences for public speaking events by leaders. Or large industrial projects on the coast of Texas that use large tanks of compressed methane and LOX. This seems like the kind of thing that you can send in the mail to another country in a special box that can open up when it senses that it has arrived at a destination so the drone can fly off to get into position for an attack by hiding itself in some nook on the roof of some nearby industrial building. Put a small solar panel on it so that it can sit indefinitely, waiting for the signal to strike a target. Or put a dozen or so of them on an unmanned surface vehicle like the Ukrainians did and send them out to a juicy port target. The biggest threat that a weapon like this poses isn't just from the initial destructive capacity, it comes from the possible difficulty in attributing the source of the attack. How do you respond to this kind of weapon you don't know who used it against you? |

| ▲ | baron816 22 minutes ago | parent | prev | next [-] | | I’ve been worried about the same thing, but I’m more worried about it being used as a mechanism for deploying chemical weapons. | |

Ted Kaczynski did much damage with them. Needless to say, direct mail from Kyiv to moscow is not straitforwards these days. And sending secret explosives through third country mail services is frowned upon by postal workers. Fedex even charges a premium when shipping killbots overnight. |

| But why?? We have had rocket powered anti-aircraft interceptor drones that go at mach 3 since 1955. |
| |
| ▲ | throwawayffffas an hour ago | parent | next [-] | | Cost, your average stinger cost 38000 dollars in the 80s. I am guessing here but they are aiming at a price of probably under 10000 dollars. Now why doesn't anyone take a rocket and stick the drone guidance on it? Again I am only guessing here, the drone guidance components probably can't cope with 2-3 mach. At 1000 meters per second with a 60 fps camera you advance 16.6 meters per frame, add to that the latency of whatever guidance system you have. You are looking at 20-30 meters offset between frames. Better guidance probably balloons the cost to the 10s of thousands of dollars. | | |
| ▲ | throwawayffffas an hour ago | parent [-] | | Oh and probably loiter time, the rocket is you shoot and it's gone. The interceptor may have enough battery to fly around for a few minutes looking for the next one if its target is downed by something else. Plus you can probably recover these if they miss. This is all very speculative though. |

| ▲ | Stevvo an hour ago | parent | prev | next [-] | | Anyone can build this style of interceptor with commercial off the shelf parts for a a few thousand dollars. It's also reusable.
A rocket for the same budget will be unguided and single use. Not useable as an interceptor. | |
| ▲ | tormeh an hour ago | parent | prev [-] | | Maneuverability and cost. Why this specific stunt? Marketing, presumably. | | |
| ▲ | throwawayffffas an hour ago | parent [-] | | Maneuverability not so much modern AA missiles can pull over 60gs. That capability costs 100s of thousands of dollars though. |

| Speed is only part of the story, but probably the part that can sell the capability of drones today. How good are they at intercepting another maneuverable aircraft either autonomously or FPV? At what speed is the drone starting to be limited by the human pilot relying on a camera feed? |
| |
| ▲ | tokai 10 minutes ago | parent | next [-] | | No speed is the most important factor. You have a very limited window to get the munition on target. An in Ukrainians case Geran drones drones don't maneuver much, if at all. | |
| ▲ | throwawayffffas an hour ago | parent | prev [-] | | Speed is really important because at these speeds they can probably intercept drones flying with low cost jet engines. So it adds a huge capability. |

| Did nobody read the article? It's quite clear. "Quantum Systems Group reckons it has broken the flight speed record for an electric drone." |
|

| still 100 mph less than piston-powered airplane speed record. Or 150 less than Tu95. Drones should be able to go that fast too |
| |
| ▲ | tormeh an hour ago | parent | next [-] | | Maybe, but the budget for an interceptor drone is much much smaller. Unless it fails at its job an interceptor drone is only going to be used once. | |
| ▲ | daveguy an hour ago | parent | prev [-] | | Yeah, big 'ol asterisks in this "world air speed record". This is for electric-powered flight, and is equivalent to 57% of Mach-1. |
