    Lower speed and altitude mean it is harder to detect both by radar and IR sensor due to higher clutter level.It is much harder to find any aircraft in hot surface background. When the altitude is low enough the pilot can turn aways if he want with very small chance of being detected. At the same time thicker air at lower altitude aid maneuver for missiles evasion in worse case senario. It is tactical sound than your tactic of turn away immediately and get on full reheat knowing full well that they will see you.

    What? I never said turning away was a good idea. It is someone else who mentionned that possibility.

    If you continue head on towards the target, you’re still flying at about mach 1. Closing speed would be real fast. If you launch at high altitude it would take too long to really get to an altitude low enough to really have an effect wrt the range of the enemy sensors.

    Even if you are not engaged until your salvoe has reached the targets, the survivors will have the advantage at this point, so it will be their turn to have fun with you, given that you’re out of missiles and in a low energy state.

    AEW is changing.

    [ATTACH=CONFIG]251524[/ATTACH]

    Pictured is the SW4 UAS with a Leonardo Osprey panel shown flank mounted. Thats a light chopper with an x00km ranged AESA set with comprehensive air-air modes. You then look at something like an Orka1200 being able to lift a 3 panel fit or a Seaspray 7000 type rotator array (of the type now fitted to RN Wildcats….also being used to supply the air picture) on an airframe good for 8hrs on station and sized to allow perhaps 3 to fit into the hangar spot of a single MH60 or Wildcat. You suddenly have any hull capable of operating a pair of Lynxes being able to deploy a single medium chopper and 24hr AEW and ISTAR capability.

    If you look at DARPA TERN its easy to conceive of a podded type arrangement similar to LM Vigilance for Leonardo Osprey on the TERN outboard stores stations. You get 20 mile racetrack AEW patrols off a pair of fixed wing UAVs at range and with E-2 type time-to-station numbers. You can fly that off an LPD or a DDG. The radar is already going on the new Firescout system for USN and as an X-band AESA offers interesting potential for SM-6 update.

    E-2D is a great capability package but its a capability that needs a lot to deploy it. If you can get 70-75% of its capability with a STOVL deck or even an LPD pad and 20-30% of the cost-to-deploy the argument for E-2 as a deck-layout driver drops a very long way back.

    That could be an interesting concept, but maybe a bit light to protect a CBG. Maybe I’d try it with a stealthy corvette armed to the teeth SAMs to engage the enemy planes before they launch and be networked with the planes. They could deploy about 300-500km in front of the CBG. They would have to be very stealthy for it to work.

    The relevance is that it doesn’t have much range!! Add to that that it would be particularly dangerous to deploy it far from the carrier because of its low speed and it’s not really a amazing system let’s say.

    It is stupid to spend so much on a carrier and aircraft that cost a fortune and not field a good EAW capability to go with it.

    The USMC is in another situation as they would be helped by the CVNs if needed.

    I´ve seen footage of a Seaking ASAC 7 flying over the Thames controling the air space over… Paris, thats around 350 km´s away. While no Hawkeye, ” rather limited” might not be an entirely fitting description.

    If by controlling airspace you mean tracking airliners I’m not particularily impressed. It’s not better than a good fighter radar.

    No budget. This was no question of “Crowsnest or E-2D”, it was a question of “either use what you have or say goodbye to the AEW capability”.
    I think that the RN is entirely aware of the capabilities (or lack of them) of Crowsnest, thats why its an interin acqusition, its demise date is 2029, enough time to get/pay the JCA´s/JSF/Dave B and get budget space for “something”.

    Cheers

    Then they should have gone with a cheaper carrier design to have the money to fund a good AEW system.

    According to Red flag comments, F-35 run out of missiles still staying in the area and act as sensor for the fleet. Talking about naive, if F-35 think he will be detected right after he turn always then there is not much motivation to turn aways and alot of motivation to just reduce speed and altitude

    Which will get you close to the enemy planes real quick without missile and with reduced energy. Good luck if your missiles miss!

    Talk about an half-baked tactic.

    “The least one can expect” doesn’t tell us much. The F-35 can fire first most of the time with a head on attack, but it’s after the launch that it gets complicated. They have surely looked into how to egress with the minimum probability of counter attack, and doing a u-turn or trying to go through the enemy planes may not have turned out to be the best solution.

    I wonder about the possibility of turning 90 to hide the exhaust, without the AB of course, and bank the plane about 10 degrees to increase the reflection angle to lower the RCS from the side. They can study the RCS from all the inclination angles from the sides to figure what’s the angle that reduces the RCS the most. The pilot knows where the targets are on his HMD so he might be able to bank the plane at the optimum angle. It might be possible to do that at relatively long range, 30+km or so. At shorter range maybe not so much.

    Yeah the problem is that the crowsnest is a rather limited system. Low altitude, limited radar size, limited speed, high vulnerability. A E-2D would be a quantum leap capability for such a large carrier like the QE. Or maybe a AEW version of the V-22 would have been possible without CATOBAR, with maybe 80% of the capability of the E-2.

    There are the none gun crowd.. never thought i see a none missile crowd as well 🙂

    Frankly the lack of gun is the last of your worries if you’re out of missiles.

    New outer wing set for F35C

    Source:
    DefenseNews.com

    That issue with the 9X is really not important. The F-35C could carry it on other pylons, no need to spend millions on each plane to change the wingtip. Even at that, carrying the 9X would increase the RCS, so frankly it’s not such a good trade-off.

    What’s much more worrying is the oscillations at take-off. I doubt they can ramp up as long as that problem is not solved.

    The assumption is that F-35 will turn aways immediately after it launchs missiles, why would the pilot do that ?

    AHAH you’re absolutely certain you have no idea about that? How about maybe, it’s run out of missiles and he doesn’t want to approach the targets?

    F-35 fans are so naive sometimes. Which doesn’t mean that the F-35 doesn’t have advantages either.

    So Su-35 pilot only know he been attacked once F-35 is already run aways ? what if F-35 pilot reduced speed after launch instead of turning away immediately ? what if F-35 pilot descend to lower altitude once he launched his missiles ?

    If the F-35 turns away right after launch it will be detected within a few seconds by the IRST. The F-35 would have an advantage not by that much, all the more that the F-35 would probably be launching in supersonic so its turn radius would be much longer than that of the Su-35.

    They have been carrying IRST since Red flag 13-3
    https://theaviationist.com/2014/02/21/red-force-exposed-nellis/

    Typhoon has IRST too.

    I know they have some IRSTs, but in the video they don’t have them. Any proof that they had them in RF 17-1? Again, was the agressor considered killed right away after the F-35 launches? If yes it is too simple a scenario.

    Sniper-XR has air to air mode too. Technically speaking, IRST are IR while Sniper-XR is CCD/ IIR /laser spot tracker sensor. So Sniper-XR is like an IRST system with more variety of sensor to choose from.Not to mention the resolution is better than all IRST
    http://i66.tinypic.com/2mot5dt.jpg

    Then why does the F-15SG carry both the sniper and an IRST:
    [ATTACH=CONFIG]251471[/ATTACH]

    30 km detection range by IRST vs >200 km targeting range by APG-81, i think F-35 will be fine

    30 km detection range head on more from behind, especially if the F-35 is using its AB. If you want the AMRAAM to have a relatively good pk, the F-35 has to shoot from not too far, or the su-35 is likely to avoid them, either by turning away and accelerating, or with evasive maneuvers. And the F-35 will only have 120C for a few years.

    The F-35 cerainly has a big advantage of being able to launch first, but you have to look carefully at how those kills are counted at RF. As I said before a WVR missile has much better chances of success than a long range BVR shot. And think about it, if you were an su-35 pilot and if you managed to see visually an F-35, wouldn’t you shoot everything you’ve got at it? I certainly would try to shoot my 4 archers at it at once!

    That is incorrect. Fighter fire control radar is almost always in Doppler mode, otherwise their screen will be saturated with side lobes reflection.Iam just gonna quote myself here

    That’s why doppler radars have been invented to be able to do look down shoot down right?

    I think it depends on whether you had back up or not. If you had back up then it is good to turn 180 degrees and run because you can bait enemy fighters into your back up. Tail chase range of missiles isn’t very long in most case.
    Alternatively, descent below cloud after missiles is launched is a good defense too. Cloud reduces IRST range significantly ( near useless) while you can still use your radar to guide your missiles
    Side aspects has higher RCS but much lower Doppler shift

    Doppler radar modes are mode for look down shoot down.

    If the Su-35 sees the F-35 when it turns away immediately after launch, it knows it’s been attacked, so it can turn away immediately too to avoid the AMRAAM.

    Not all agressor F-16 had the new IRST pod.

    Pretty much the same thing. Sniper-XR has air to air mode too

    Any source that they really did carry the IRST? The Sniper is not a real IRST, although it can be cued to tracks obtained by other sources.

    And if the F-35s face the same number of Su-35s, they would all have IRSTs.

    Which aircraft are you talking about? By the end of 2018 the USAF and USMC will have 2 operational squadrons each and the USN will be getting aircraft to complete its first one. 3I to 3F is a minor bump compared to 2B to 3F bump. One must remember that a vast majority of the current 2B fleet aircraft in the USAF are in non operational squadrons i.e. those being used for testing, and tactics and training. At least one of the two operational squadrons by the end of 2018 will be 3F and it is highly likely that both will be since the USAF IOC’d with 3I which included the hardware. From there on in all deliveries will be in 3F configuration and won’t require hardware upgrades till Tech Refresh 3 slated for the 2020s.

    The interim capability will only work if the USAF ever intends to transfer the 45 2B jets to operational squadrons and if so, how many and which squadrons (and when). You have to see what those 45 aircraft are doing and what capability will be lost if you operationalized all of them. Running a new software program that acts as a 2B to 3I bridge (i.e. higher 2B capability without 3I hardware) is going to take manpower which takes away from both the 3F completion and the FOD. It will also require additional resources which would have to be pulled from somewhere.

    After the first two operational squadrons are delivered by late 2018 they will begin a two year process of delivering 54 aircraft to Eilson after which they will move over to the squadrons at RAF Lakenheath.

    If the SHTF with China they’ll use anything that can fly.

    I watched that esterday:

    I didn’t see any Agressor F-16 with IRSTs. The other F-16s had sniper pods, but the sniper is not a real IRST.
