What do you think of this? I want it to be NATO designated Ferret because the animations show it running around like one.

Expensive toys which won't really change anything as far as I can see. Almost all wars are proxy wars against 1970's era tech countries or insurgents nowadays. Even with a conventional payload these things are far too expensive to waste on that.

Low flying supersonic missiles/UAVs seem more likely to be relevant, even then only to one conflict ... China Taiwan.

Low flying ones yes, but that's not what Russia is talking about.

Would Russia advertise its cutting edge capabilities like that? I always assume powers don't give away their latest and greatest, or have alternative motives. There's something to be said for having your adversary spend a lot of money and resources on a phantom threat. One of the benefits of having a single long term leader is that you can effectively play long games, rather than changing course every 4 or 8 years.

Of course they would - even if they didn't have the capability!

That's the entire rationale behind M.A.D.

Even on a smaller scale, a two-by-four LART can deter an attack, or consider that a prime benefit of a burglar alarm is to persuade a would-be thief to go somewhere less risky.

Sure, but it pays to have an ace in the hole. The US didn't reveal its stealth bombers until they became old technology either, although we should assume the people most interested in that probably already knew more.

like this but I made the impedance/angle wrong, I think it has a bad impedance but a wider doughnut

its twice as high as wide rather then equal width and height for 50 ohms

so its like 55 degrees from the point.

So more than 25000 wounded, more than 10000 dead and more than 20000 houses destroyed in UK during V1/V2 WWII campaign was imaginary to you....

You confuse consumer items (like smartphones) with military/space technologies. Former USSR didn't care about consumer items, so they didn't even try to make it. They put their efforts solely to military applications. And made many highly sophisticated and many not so sophisticated but highly effective weapons systems..  They had and still have fantastic scientists and are at the cutting edge in many areas...
The fact that they don't make pink smartphones for teenagers is irrelevant in this discussion..

You can make 3000 malds for 60mil.

look at cost and complexity of s400 system and how many are in service

400 million for 112 missiles.

its 20k/3.5 million, same exchange rate as the rubble pretty much

you can probably program the non destroyed ones to land so you can reuse them too.

And fanboy nationalist "my nuke is bigger than yours" discussion is always leading nowhere.

None of us here have NO CLUE about real capabilities of any weapons system that is cutting edge. Vital parts of specs are highly classified.
All public statements are marketing, propaganda and most of the time outright disinformation.

Only real thing is that all this "better this, better that" is crap. Even old USSR (or USA) missiles from 1960ies can wipe out whole Europe in few minutes.

And yes, Russia and China are superpowers, have very smart scientists and are at the cutting edge of research in many areas..

I see the appeal of being able to shoot down a ballistic missile that is launched by accident, its actually probably a good thing to have a few of these sprinkled around by different actors to keep the world safe. If something goes wrong its not the worst thing to have a independent party with different command and control systems to essentially save the world.

On the other hand, it is more dangerous for commercial and private space traffic, because someone can possibly shoot down something non military by accident. The more reaction time the better, which hypersonics make scary. Someone like India might actually contact the Kremlin or NORAD to confirm whats going on if they have time. If there is no time then kaboom. 

However, to call it a air defense solution against NATO is kind of a joke, it is just not economical. They will deplete your missile stock pile, then go back to an aircraft carrier and come back later at best. It is too expensive.

Well, with military hardware cheaper is better because it should never be used and it hurts everyone progress as a society to pay for that. Russian apartment building and road condition vs missile force condition...

Robust scientific equipment is essential to progress though IMO.

Did US find WMD in Iraq? That's was an official reason for invasion. In Iraq, Afghanistan and Libya US caused more human deaths than all of dictators combined. And now those countries are in poverty, experience power vacuum, and are ridden with terrorism. They were much better places with those dictators.
Talking about Syria, among Muslim nations it was among those with most of human rights. US supported rebels and did not admit those were linked with terrorist organizations. Only relatively recently they admitted IS in Syria. And now EU needs to deal with all migrants flowing from that region. Nicely done.

alright why was he not letting weapons inspectors do their thing as per the treaty? he violated a treaty. no one knew what was going on. its like someone violating their parole. do you just let that slide? whats the point of a treaty then? did they say his government needed to obey 50% of it? what do you do invade it, write up all this paperwork that is supposed to bring justice then just let it slide?

normally for that to happen in court there needs to be alot of good will and cooperation and public good stuff going on. this guy was just like a con that wont let parole officers into his house. and he did not do any community service or nothing. what are they supposed to do? he did a bunch of crazy bad shit, got off on a treaty and then started interfering with everything. you cant do that in a civilized world, other wise no one will ever decide to do a treaty to end a war. look what happened after WW1 treaties were being violated.

There were inspectors and they did not find anything. US still proclaimed Iraq was hiding their WMD and started the war.

Quote
In late 2002 Saddam Hussein, in a letter to Hans Blix, invited UN weapons inspectors back into the country. Subsequently, the Security Council issued resolution 1441 authorizing new inspections in Iraq. The carefully worded UN resolution put the burden on Iraq, not UN inspectors, to prove that they no longer had weapons of mass destruction. The United States claimed that Iraq's latest weapons declaration left materials and munitions unaccounted for; the Iraqis claimed that all such material had been destroyed, something which had been stated years earlier by Iraq's highest ranking defector, Hussein Kamel al-Majid. According to reports from the previous UN inspection agency, UNSCOM, Iraq produced 600 metric tons of chemical agents, including mustard gas, VX and sarin, and nearly 25,000 rockets and 15,000 artillery shells, with chemical agents, that are still unaccounted for.
In January 2003, United Nations weapons inspectors reported that they had found no indication that Iraq possessed nuclear weapons or an active program.

bad choice of words on his part


In 2001, Saddam stated: "we are not at all seeking to build up weapons or look for the most harmful weapons . . . however, we will never hesitate to possess the weapons to defend Iraq and the Arab nation".

thats not even denying it or saying we don't have any. its some passive aggressive threat shit.

you don't say that if you gassed a town before.

this level of cooperation is unacceptable if you committed a genocide
On March 7, in an address to the Security Council, Hans Blix stated: "Against this background, the question is now asked whether Iraq has cooperated "immediately, unconditionally and actively" with UNMOVIC, as is required under paragraph 9 of resolution 1441 (2002)... while the numerous initiatives, which are now taken by the Iraqi side with a view to resolving some long-standing open disarmament issues, can be seen as "active", or even "proactive", these initiatives 3–4 months into the new resolution cannot be said to constitute "immediate" cooperation. Nor do they necessarily cover all areas of relevance." Some U.S. officials understood this contradictory statement as a declaration of noncompliance.

For those who are interested, Russia/USSR has a long history of developing quite sophisticated UAVs since the 1950s, using powerplants from turbojets to ramjets. They were designed for a variety of roles - many were reconnaissance drones with quite interesting mission profiles, such as that for the Tu143, below. It's big brother, the Tu139 was a fully reusable UAV, with a very impressive capability.

Indeed, the Russians were developing UCAVs in the early 70s, the Korshoon being a noteable design. This was capable of carrying a 1,100lb warload, though the system never flew as the CofM Presidium's Commission on Defence Matters ordered Sukhoi to turn the project over to Tupolev. Development ground to a snails pace after the end of the Cold War, however - for a while the Russian Army only had the Yakovlev Pchela-1T in service, with the distinction of having seen action in the Chechen Wars.

The Russian's have long taken a different approach to UAV/UCAV design and mission profiling - they were really leading the forefront of such design ab initio, until the end of Cold War. The developments made since the mid 00's (primarily pushed by Russian private companies funnily enough) have made real progress and the UAV/UCAVs we see are entirely within their technological means.

It was. Some people are currently investigating if they can retrieve one that sunk in a lake according to eyewitnesses.

Would be cool to see that, for sure.

At least since WWI there have been efforts to develop overwhelming superweapons.  Many have been developed and deployed.  All with claims of how the opposition will be helpless against them.

Some have been used in battle over the years.  And in many cases the results on the battlefield were dramatically different from the pre-use marketing hype.  Reasons include lack of real capability, inadequate quantities, poor application, unpublished capabilities from the other side and many others.

No one has the sole set of keys in this area.  All players have weapons with very high lethality.  I suspect if they are used in earnest there will be many surprises on both sides of the conflict.  The only sure path is to not use them and convince others not to also.  Which is unfortunately in the same difficulty class as developing these super weapons.

I love those old automatons, it's amazing what you can do with only gears, cams and linkages!

The main difficulty with navigation is that errors tend to accumulate over time. That is why IMUs are difficult to make since the tiniest amount of noise and bias will quickly add up to a catastrophic error. You really need additional information from sensors to give you absolute location data every now and then. I wonder if they might have used some, for the time, advanced radio navigation system, or radar or some such. If they were supposed to take photos/video, knowing the correct position would have been important.

It's not just IMUs. You can measure the magnetic field, airspeed, altitude, time and more. Combined you should be able to pull off some fairly fancy flight patterns. Considering some of the navigational tricks that were pulled off with radio beacons in WWII, that seems a real possibility too.

Hey, I'm not stopping you, go on and tell me how a missile is both a glider and hypersonic?  About the only way that makes sense is if the missile is a powered missile for most of its flight and then, as it nears the target, the engine is cut and it 'glides' to the target.  That might reduce the thermal image a tad, but only a tad as the nose and leading edges are going to be frickin hot. 

But, again, please do enlighten me...

It has huge kinetic and potential energy and glides in upper atmosphere layer where drag is tiny compared to drag at sea level. At such altitude it's more difficult to reduce speed rather than keep it high. The issue is withstanding high temperature for prolonged time.

Interesting. That would work well for aircraft that fly above the troposphere (those ghost rockets were supposed to fly very low though). I'm curious how they could pull off astro navigation in the 60s without CCDs and computers (CCDs were invented 1969 according to wiki) was there other types of image sensor before that?

Brian

I don't think anyone is saying that there is a free lunch... There are numerous varieties of missiles, and plenty of ways they travel. Many missiles flying at ground level have a motor which burns for a short period, leaving the vehicle to travel along a ballistic trajectory to target. Other missiles such as the BGM71 have much longer burns, and can flown to target with wired controls - so long as the motor produces more thrust than the weight of the vehicle it will fly (ie, thrust to weight ratio > 1).

Planes, gliders, and hypersonic gliders, have mechanical features which also generate lift. Most planes use wings to do this. Other aircraft, such HGVs, rely on the shape of the body to generate lift. HGVs rely on skipping on a boundary of thicker air, similar to how a stone may skip on water. The stone 'flies' along this boundary for quite some distance, skipping multiple times and rising into the air despite having no form of thrust. An analogy can be drawn to the mechanisms behind HGV flight.

You are correct when you say there is no free lunch. You are incorrect when you say hypersonic and glider are mutually exclusive terms.

I'm curious how they could pull off astro navigation in the 60s without CCDs and computers (CCDs were invented 1969 according to wiki) was there other types of image sensor before that?

I'd also be interested to learn about this tech. I've heard stories about it, but nothing in any detail. :(

Use the vacuum tube, Luke! (https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19670021967.pdf)  (Either photomultiplier or image-tube).

You don't need CCDs to track stars because you can use use a star tracker: https://en.wikipedia.org/wiki/Star_tracker   These were used in 50's & 60's missiles for navigation.

Here's some background on automated celestial navigation systems: https://ad.usno.navy.mil/forum/kaplan2.pdf    (Firefox gave me some security warning)  Probably used a Photo Multiplier tube on a sextant.

Being aerospace, it'll have all sorts of mechanical gew-gaws on machined aluminum structures all connected with those neatly laced wiring harnesses.  Be neat to have one to play with.

Cheers,

You could keep a telescope with a photo multiplier at the eyepiece pointed at a star and then measure the angles, you would need one for a few different stars. But what would you do if you loose tracking, how find back to the right star again? It seems like it would easily get lost.

This weapon could reach Sydney within 35 minutes of being launched from Moscow, thereby wiping out the EEVBLOG. Putin would not be so stupid. Even Trump first checked if the EEVBLOG would be affected prior to shutting down the US federal government.
