US Stealth Jet Has To Talk To Allied Planes Over Unsecured Radio

Lasrick writes "David Axe at Wired's Danger Room explains: 'For the first time, America's top-of-the-line F-22 fighters and Britain's own cutting-edge Typhoon jets have come together for intensive, long-term training in high-tech warfare. If only the planes could talk to each other on equal terms. The F-22 and the twin-engine, delta-wing Typhoon — Europe’s latest warplane — are stuck with partially incompatible secure communications systems. For all their sophisticated engines, radars and weapons, the American and British pilots are reduced to one-way communication, from the Brits to the Yanks. That is, unless they want to talk via old-fashioned radio, which can be intercepted and triangulated and could betray the planes’ locations. That would undermine the whole purpose of the F-22s radar-evading stealth design, and could pose a major problem if the Raptor and the Typhoon ever have to go to war together.'"

The only mitigation against discovery through listening in passively to the Raptor's transmission is to either devise a system to transmit on multiple frequencies in a way that cannot be distinguished with background noise, or hop frequencies in the hope that the eavesdropper won't be able to match the signal for more than a fraction of the time.

      Triangulation against a jet is just barely this side of useless - the damm thing is flying at several hundred miles an hour. A second or two after he stops transmitting, your triangulation solution has lost significant value because he's miles away from the datum point. Your solution just degrades from there and by ten seconds or so you might as well have been using a Ouija board.* Has anyone actually deployed the RDF gear that would be required for high speed tactical 3D triangulation? It's not particularly high tech, but it's also something that can't be cobbled together on short notice out of 'stone knives and bearskins'. To be any kind of useful, you need high accuracy (within +/- a degree or so), which means sophisticated antenna designs and significant signal processing. (Real life RDF isn't a simple as it is in the movies.)
       
      Another problem you face is that you can't use triangulation to fire weapons... you need some way of handing the track off to the radar needed for SAM's or AA guns, or off to the fighter which will then need to obtain radar or IR lock to fire a missile or to obtain visual contact.
       
      So, the real problem isn't triangulation... it's breaking stealth. An unsecured transmission can provide a raid warning. It can warn radar operators to pay really close attention to the 'fluff' on their screens. Etc... etc...

In all likelihood, the Air Force is unwilling to share the Raptor's targeting data, as they don't want the operational capabilities of the radar/IFF/command and decision systems to be revealed to anyone, including one of our closest allies. Such data can reveal the range of the radar, the resolution, and the characteristics of the radar when it comes to jamming and clutter. Obviously, all this data is classified as secret or above, and is almost certainly not for release to foreign individuals.

    Remember, the F-22 is the only airborne weapons system that the US Government refuses to sell to other countries, because it's an apex predator. There's nothing out there that can rival it, and even the F-35, which is basically a follow-on of F-22 technology, is no match for it. Thus, we'll sell it to allied countries, but the F-22 stays US-only, in the case that if we're ever involved in an air war where we're back to old school air superiority, there are no air forces that can match ours.

    That said, I remember reading an article a couple weeks ago, where a new pod is being installed in several US fighters that allow for interoperability with the F-22, over a form of encrypted radio. Basically, the pod allows the fighters to act as a sort of wireless access point, which interfaces with the F-22 and any other fighter with radios that don't talk the same language.

    The F-22's design is over 20 years old. Think about what data networks looked like 20 years ago compared to today. Considering that the F-22 is an air superiority fighter and the current war is against an enemy who has no air force, I can see how the F-22 might not be at the top of the priority list for a comms refit.

    A good question is how much radar data from passive only F22 is to a typhoon that has its active radar powered up. F22 essentially cannot fire up its radar and stay stealthy for obvious reasons, so its passive radar only. The major part of data link is sharing targeting data. F22 is designed to feed off allied aircraft's search and fire control radar data for both target acquisition and weapon guidance.

    Not having proper communications link is a bitch, that's certain. But F22 is just not designed to be fighting alongside aircraft it needs to talk to in the first place. It's the silent hunter that doesn't really see anything on its own, and just listens to what allied aircraft tells it via datalink or what it can scrounge up from passive sensor data, and then performs interception based on that data. It apparently can also occasionally fire up its own fire control radar in short pulses to minimize risk of detection, but it's simply not intended to be an actively radiating aircraft.

    The stupidity here is that it has no standard NATO datalink for cases where it has to perform other roles. It's one of the reasons why F22 hasn't seen any combat to date. There are no pure air superiority missions in the modern world for US airforce, and F22 is pretty incapable of doing anything properly else because of the way it was designed. Lack of common data link is just one of the design choices that hurts that aircraft really badly when it comes to doing anything else.

    You just triggered a thought. It is possible to build an emitter (transmitter + antenna) that simulates a completely different emitter, including a diffuse one. This is done by working backwards from the far field equations. This was originally done (AFAIK) to develop a sonic equivalent of a laser that worked underwater - the scientists worked backwards from the far field equation for a coherent sonic beam, and successfully came up with and built a sonic emitter that resulted in the desired coherent beam. Another recent related example of working the equations are the successful experiments in 'invisibility cloaks'. So by determining what the far field of a diffuse emission would be, it should be possible to build a radio transmitting system that was essentially invisible in the sense of determining where it came from, at least from a significant distance.

    In fact, a similar methodology might be effective in countering the latest threat to stealth - reading the disturbances in the milieu of the many terrestrial radio sources such as cell towers and power lines. As early as the Kosovo war, experimenters successfully located stealth planes by measuring the distortions in the field that is generated by the cell tower network. This is somewhat like seeing the distortions of ocean waves caused by islands or other fixed objects. So, by continuously monitoring those fields, a stealth plane could compute the necessary interference to make its own distortions of the fields disappear.

    Well then you have a problem because while it may be argued that the ends justify the means, that argument falls apart when the means contradict and thus prevent the ends.

    All-out-war is over because the political goals of war have changed. You simply cannot fight a war of "liberation" without respecting the civilians. And this was self-evident in the years of complete and utter failure in Iraq. Sure, we didn't engage in "all out war" against a poorly understood collage of insurgent forces because that's a completely ineffective way to fight an insurgency unless you're willing to go the Roman or Mao Tse Tung route and use genocide. Which would have resulted in us "winning" for a definition of "winning" completely different than what we started with. The warfare equivalent of flipping the chessboard. Good job. You "won". Slow clap.

    So instead we tied our soldiers' hands with rules of engagement while simultaneously maintaining a flippant attitude toward colateral damage -- enough to "look nice in the papers" back home, but definitely not the ones in Iraq. This was because the people in charge, like you, really would have rather engaged in all-out war but knew they couldn't because of politics at home.

    The result was unsurprisingly ineffective as the ranks of insurgents swelled with angry former-civilians (many of whom were former-army, but don't get me started on that).

    A lot of people credit The Surge with turning Iraq around, but while a component it was actually the least important part of what changed. Petraeus' real genius was in not only using force even more judiciously than before -- the opposite of what you would do -- but also in fully engaging the civilian population. He didn't treat them as though they were basically the enemy that he couldn't shoot because it looked bad on CNN. He treated them as if they were already allies that required help. He took "winning hearts and minds" seriously, and it worked. When the area of Iraq Petraeus was in charge of stabilized like none of the rest of Iraq had, they put him in charge of the lot so his demonstrably effective (and not coincidently completely unlike your) strategy could benefit everywhere. And it did. Only in the environment created by this new strategy could the additional troops put in have been effective.

    You know what the REALLY sad part is? The part that really causes comments like yours make the bile swell up in my throat?

    It's that when we began in Afghanistan, the people did support us. Unlike the Iraqi people who felt betrayed by us after Desert Storm, the Afghan people still thought of us as the folks who helped them kick out the Russians. With no love lost for the Taliban, they were actually on our side. At first.

    Thanks to years of idiotic management, that flippant attitude towards collateral damage you embody, and years of neglect due to being focused on Iraq, we lost both literal and figurative ground in Afghanistan. We squandered our advantage. Pissed it away. Turned the people against us.

    And then some dweeb comes along and says the people "will never support us". As if it was always this way. As if it's their fault, instead of ours. Gee, maybe we should just stop worrying about killing them. That would probably fix it.
