While it is possible drones will make quite a few advances in combat i do not expect to see them intruding too much in fighter to fighter role. Reason being, we as humans seem to have a huge fear of allowing autonomous vehicles handling too much for us.
As for technologies i do expect some serious advances in the near future for fighter aircraft. One of the ones is a quasi cloaking device ala shield helicarrier in avengers. Believe it or not the british have a prototype of it that they tested on a challenger MBT and it seemed to work as long as the vehicle was still. Mind you this was several years ago and i know the USA has access to the same tech and i wonder quite seriously how far along we have gotten there on that. https://www.youtube.com/watch?v=x2csY8b-ywg |

Ah yes, i remember seeing that technology in tv tech show about a ~decade ago, but on a special made coat and on a car. Last i heard they don´t seem to have gotten much further than they already were then(i expect the tank test was somewhere around the same time). One issue that i know of with it, is that it does zero in regards to thermal imaging or image enhancer technology, and IIRC someone figured out a way to use the projection system as a beacon, so while it looks cool, for the military it seems to be very limited in how it can be used well.
Well, considering how easy it is for a programmer to miss a bug, do you really want an autonomous fighter that suddenly "realises" that everything around it are hostile targets? Just as an example... |

Your previous argument sucks
Changed your stripes. That is certainly NOT what you said. You claimed 16s cheap price was reason 20 never got customers. Ain't true. Are you that unaware that no fighter can take damage and keep flying as their engines are surrounded by fuel? Why AtA missiles have a shrapnel head...
Not true. It is all about situational awareness. IE your sensors. RADAR/IRST. Missiles lock on 360 degrees now. Aerodynamics are useless as a distinguishing factor except when reduced to your machine gun. Prior to 360 lock on target, one had to actually maneuver their fighter to get a lock.
[quote="Tenshinai"] [quote]Russia are the ones that have done research in the area, there is an experimental R-73 model that can do it. The IRIS-T should be able to do it in the future. AFAIK, Israel has nothing for aircraft upcoming anytime soon. And no, there´s also countermeasures, ECM and EW, and dodging missiles by maneuvering is not an impossible thing.[quote] ECM is a bad joke. Sounds really cool and intriguing, until one turns a light bulb on. |

You should probably learn to read before starting to shout. I said that all the subsidies it got made it far more enticing than it´s real pricetag would have.
Actually, some modern missiles have drastically different warheads, exactly because shrapnel isn´t very effective compared to weight. Your statement is also blatantly proven wrong because there´s a LOT of fighters in the last 70 years that have taken damage and keep flying. And well, you DO know that fuel tanks that are resistant to explosion are kind of old tech? There´s a somewhat famous video of a Su-27 doing a safe belly landing with its fuel tanks literally on fire. That little accident gave the latest generation Russian fueltanks a BIG commercial boost as the fire didn´t even cause engine flameout, the fueltanks kept delivering fuel despite burning. I mean sheesh, have you completely missed the .50s vs cannon argument or something? Why is a .50 3-5 times as damaging as a .303 machinegun and why is a 20mm cannon about 3-4 times as damaging as a .50... I know the answers, you obviously do not, meaning you don´t have a clue what you´re talking about. Which of course you already showed by claiming something that is evidently not true.
SOME missiles can do that, most cannot. And they can´t do that because they have 360 by 360 seekers, because they don´t have that. "all about..." Situational awareness helps a lot, saying that´s the only important thing only makes you sound like a fool.
Oh boy... And if you believe that i have a few nice bridges to sell you, Golden Gate sound like a good deal for starters? In case you didn´t know, which obviously you don´t, there can be a huge difference in quality for "getting a lock on". Then there´s the little fact that if you have good aerodynamics, your chances of avoiding a missile are greatly improved. This was one of the reasons why the AIM-54 was dropped, as it was found once reliable simulations on Su-27 existed, that with a halfdecent pilot a Sukhoi could dodge Phoenix missiles all day without much to worry about. And almost as bad against MiG-29, while it´s intended targets, the naval attack planes had upgraded ECM to such an extent that hit probability had been badly pushed downwards.

You utterly missed the thread of my 1st post. With modern sensors on a platform that does not care about Aerodynamics, not how it is done where on today's fighters where Aerodynamics rule and they do not have effective spherical sensor capability, obtaining a lock in 360 is obscenely easy. Ergo the punchline A-10 style aircraft with counter missiles and true spherical sensor coverage. The tech is readily available. As per Aerodynamics: I suppose this is where I break out my Aeronautical engineering degree and tell you you don't know shit. But, that does not help matters any as the person who doesn't know shit will never be convinced unless shown. Can't "show" on the internet. But will give a glance in their direction. So, lets discuss basic rocket physics and Aerodynamics. Large long range AtA and SAM's are easy to dodge as their maneuverability sucks wind. The smaller the missile the higher its thrust to weight ratio is. The shorter the missile the lower its inertial momentum and the higher g' turns it can pull especially when combined with its thrust to weight ratio. INS spin stabilized are the size of a pack of cards today. A bit smaller in fact. With this invention, Counter missiles now become doable. Or more likely is a 'fat' form of RPG. Before this, counter missiles viable for an aircraft would have to be effectively the same size as their offensive missiles requiring a dedicated volume about 10 inches in diameter and about a foot long. No one has this capability besides the USA currently for miniature INS. When someone else figures out how to make a decent accelerometer out of solid state silicon, then they will be able to do this feat as well. Only a matter of time. When this happens, the counter missile race will be on. "ECM" is nothing but a fancy word for BLIND. There is no such thing as countermeasures. As it is singular. Countermeasure. As in blind via radar. With advent of IRST/RADAR combo sensors, such blinding is useless. Flares are also useless against multi pixel IR sensors. Only ECM one can undertake in this scenario is to KILL the senors via the use of a LASER. Of course simple use of coatings on the lens by and large completely negate most lasers if not all. To make a laser useful against a competent missile, it must have a ton of juice behind it with the ability to literally MELT through the lens before attacking the sensors in modern warfare. You might have noticed, but not even the VERY large version being tested by the US NAVY can accomplish this feat. The fact you are unaware of this fact speaks volumes about the competency of this discussion. By all means keep talking about 1980's tech taken off of military.com and Wikipedia. It is freely available to armchair tacticians. My posts had nothing to do with old tech, but rather where already available in-use technology is going to push airspace dominance. |

HAHAHAHAHA. Dude, a belly land that does not pierce the turbine engine is your example? A turbine is a gigantic pressure vessel filled with extremely HOT gas. When it gets pierced by shrapnel it releases said HOT gas into the surrounding fuel tanks and KAAAAAABOOOOOOOOMMMMMMMMM! Those tanks are only self sealing against Small shrapnel, and even then they are not. By definition, if you pierce the turbine engine the shrapnel in question has pierced a nice tidy hole between said nice very hot gas Pressure vessel, and the fuel tank! This, oh so nice pressure vessel, is a self sustaining pressure vessel with lots of rotational momentum behind it to keep on pumping that nice HOT gas into a self igniting liquid fuel that only needs its temperature raised to self ignite. Your, argument is frankly in a single word, laughable as your conceived concept of what happens when a turbine pressure vessel is pierced is woefully inadequate. |

That is partially correct. It depends on how the missile reaches its target. A good example of the worst kind of maneuverability during final attack phase is the AIM-54 Phoenix, which is effectively a ballistic projectile after its launch acceleration. That´s not the only type around however.
If you had one you could maybe do that yes. But so far all you´ve shown off points to that you don´t have anything like that.
No i didn´t. Problem is more in regards to how you seem to have missed that someone already tried your idea. There´s a Su-27 derivative prototype that has 360 by 360 sensors and full integration. It was nastier than a regular one but no, that didn´t mean it suddenly became all-powerful, even using modified Vympel R-73 missiles that could be fired at targets 360 by 360. It´s funny though how you seem to not know about the primary problem with trying to fire missiles in any direction. Or that other nations, nations plural, have done both that and done it together with similar 360 sensor coverage as the above Russian test(i use them as benchmark since they´re still playing with it and went the furtherest). Including my own nation.
It´s a pity you don´t know quite as much as you think you do. In fact, the more you write, the less you seem to know.
"noone has this capability", right. Not that it matters since that´s not the current main avenue of interest. You´re aware that the idea of countermissiles on aircraft has been repeatedly rejected? And not for any inability to design or produce such.
That normally depends on its weight compared to thrust(and limited by structural strength of course). That is, it depends on how large portion of the missile you decide to use for propulsion. Smaller missiles tend to be of the shortranged variety, and since in such a situation you need high level agility, those tend to be geared the hardest towards high trust to weight. That does not mean that larger missiles are by default less able to maneuver. That´s a severe logic fail in regards to identifying cause and effect.
Riiight. You realise how, lets be nice and call it "limited usefulness" such a counter missile would be against, for example a Vympel R-77?
Yeah, that´s the reason why everyone spends more and more on trying to make ever more funny counter measures and get ECM programming just one notch higher in quality. FYI, i know someone that programs ECM for aircraft. Your statement is complete nonsense. Not even the ECM=blinding is correct. ECM means you either mess directly with hostile sensors, communications, or indirectly by interfeering with them less obviously in such a way that it messes with their guidance packages to correctly execute instructions. There are also some countermeasure weapons that you might call ECM(various ways of trying to hit hostile missiles or guiding sensor with active emissions of sufficient strength to damage or spoof it), but just like the laser stuff, noone has made it work reliably or realistically yet.
I´m not silly enough to claim something as idiotic that only playing laser tag will work against sensors. I wasn´t even including that as a realistic ECM, because it´s not even ECM at all anyway.
Oh, there´s a site called military.com? Didn´t know about that one. And 1980s tech? Uh, right... 1980s tech that didn´t exist until a few years ago, yeah that sounds great... |
