If you zoom in on your still image ....the first digit is not a '1' ....it looks like the standard coded serial for the US

You canít really blame the Russians. The UK or the US would have done just the same. Imagine you the US are fighting a war in the US and some third party has a drone just off the coast of Norfolk but in international airspace providing intelligence to the enemy. The US would also take it down.

Itís the cost of doing business. They will have already planned for x number to be taken out, or to see how long they could get away with this and then revert to plan B, which may be moving farther south, or sticking with traditional assets. Again they will have expected and already planned for this.
Agreed, it's a calculated response. They didn't have a pop at any of the manned assets in the area, and they managed to do it without using any weapons. The US, in turn, can respond in a measured way because no personnel have been put at risk.

It's not their first, nor will it be the last

Record number of UAV shoot downs prompt new USAF tactics ...

30 June 2020 — After holding steady at a few instances per year, the number of suspected or confirmed downings of unmanned air vehicles (UAVs) grew to 14 ...

What a strange assumption, troll farm style. When did the US or UK ever "take one down"? Russia does flights like that all the time off the UK coast and elsewhere, however manned ones.

Re bending of props under load... the prop thrust per blade to cause out of plane bending its not that much, An extra is able to generate a high level of thrust, but relative to the radial load, it is going. to be fairly low, around 2.5% that's about a degree and poofteenth, however, the load ain't uniformly spread, the center of the distribution is around 0.8r, and the in plane load at that point is considerably lower, and the underlying modulus is lower still, but overall the bending is predominantly around 0.75r. Its not that big. Same for fan blades. but all bets are off when they go chomping bits of tin nearby.

Seems the EP3A now has a stable mate for outmanoeuvring soviets finest cookware.

There's a balloon club that might disagree.

That was around the chinese airspace intrusion and overflight mistaken for another one over the US, not in international airspace over international waters like the drone.

Effect of Fuel Spray

Guys, forgive the possible naivety of the question, but what effect would dumping fuel in the drone's path actually have? I wouldn't imagine the airframe would be affected, possibly some sensors would be degraded, but have no idea of the effect on the engine given the fuel would be fairly dispersed (or would it?) by the time it was ingested.

It might get blown into the air intake, clog things or start to burn inside?

If you could get the quantity correct perhaps there would not be enough oxygen to ignite the fuel and you could cause a flameout.

Do we know if the drone has any inbuilt evasive, defence measures? Surprised the drone didn't just evade the jets. It must be considerably slower and more nimble.

As an aside I remember hearing a commentator remark about the F111 dump and burn "can't think of any valid combat reason for that manouver". Now we know.

I wonder what their ROE were? If they had been sent to down it, then dumping fuel in front of it or hitting the prop seems to be an odd way of going about it. A couple of Rodneys getting carried away perhaps?

F111 could dump, then burn.

I wonder how far you would go if the aircraft was manned. Destroying a drone is not as politically sensitive as killing a crew.

Self destructed?


have they recovered parts of it? Scroll down, it says the US are going to release film of the incident.

Don't be ridiculous, everyone knows the fuel dump nozzle of an F111 is positioned between the jet effluxes so the fuel can either be dumped with the engines 'dry' or ignited by the 'burners being lit.

Makes sense. One of the drone's USPs is that you might be willing to lose one from time to time; designing it so that the wreckage isn't particularly useful to your adversary seems a pretty obvious thing to do. The airframe's probably not very interesting, and I'd have thought the sensor package wouldn't be that hard to destroy if the capability's designed-in.

if you pause the video just after the 0:00:02 marker you can see the wingtip and an extended slat. Does it look like a Su-27?
