  1. I'm nitpicking, but: longer, not shorter. At X-band frequencies (8-12GHz) the wavelength is 4-5 orders of magnitude longer than that of visible light (~350-750nm).
  2. Except for the best known RAF aircraft of all time? https://www.digitalcombatsimulator.com/en/products/planes/spitfire/
  3. However, they did provide a solution to the problem:

    CATM-88

    Ths should literally be the absolutely last thing on ED's list of priorities. If you can pretend to be flying a jet you can pretend there's a blue stripe on your missile (and not press the pickle button).
  5. I did some tests. All in the same map, same altitude, speed, meteorological conditions, with targets designated using the TGP. Having a nav waypoint nearby, with WYPT boxed or unboxed (WPDSG not used) causes the GBU to be at an altitude of approximately 3000ft + WP elevation at TTI-1 sec. With no waypoints in the mission, the GBU hits the target. With a waypoint nearby it misses if the WP elevation is too high (with a nav WP @ 6500ft it never picks up the laser). The distance to the target at the time of release is the same (~5.3nm flying at 25k ft @ 350kt) for all tests.
  6. Try opening \DCS World\Mods\aircraft\FA-18C\Missions\QuickStart\Caucasus FA-18C River Run.miz in the mission editor. Then just switch the F-18 with the F-14 and save the mssion with a new name.
  7. The sign is part of the china asset pack, not some new unannounced map.
  8. Please read up on how pulse doppler radars actually work instead of just making stuff up. As an example, in X-band (10 GHz), a target approaching at 50kt (25 m/s) will give you a frequency shift of 1,7kHz. Detecting this using FFT is trivial.
  9. Apparently the GP frequency has been copied over to the localizer. The correct LOC frequency for a 333.8 MHz GP is 109.9 MHz. As a temporary fix (while we wait for ED to fix it) you can open the beacon file (\DCS World\Mods\terrains\PersianGulf\Beacons.lua), find the section { display_name = _(''); beaconId = 'airfield2_2'; type = BEACON_TYPE_ILS_LOCALIZER; callsign = 'IBND'; frequency = 333800000.000000; position = { 113693.740992, 5.776140, 13154.132035 }; direction = 28.001016; positionGeo = { latitude = 27.198930, longitude = 56.367921 }; sceneObjects = {'t:200671295'}; chartOffsetX = 4544.000000; };and replace 333800000.000000 with 109900000.000000 Note: Make a backup copy of the file before changing anything. The multiplayer integrity check might be an issue.
  10. Isn't Super always better? Just imagine how bad a film "Man IV: The Quest for Peace" would be...
  11. The manufacturer's data says nothing about the test conditions. Bolting the gun to a solid test bench is not necessarily comparable to firing it from a plane. Vibrations from recoil doesn't change the dispersion of the gun itself, but it does change where the gun is pointing.
  12. The file is part of the China asset pack. \DCS World\CoreMods\aircraft\ChinaAssetPack\Shapes\Static\biaoyu.edm

    F-15E?

    Someone obviously didn't catch that Fleet Aviation Gazette is basically The Onion with planes. https://fleetaviationgazette.com/2019/04/16/squadron-loses-joint-strike-fighter-after-maintainers-forget-to-unbox-invisible/ https://fleetaviationgazette.com/2019/04/20/p-8-to-be-armed-with-dick-glitter-bombs/
  14. Actually, you are under-thinking it. Altitude AGL makes no sense for a GPS guided bomb, since the bomb has no idea where the ground is below it. JDAMs, JSOWs and all other GPS guided weapons use HAE, Height Above Ellipsoid, which gives you the height referenced to the WGS84-ellipsoid. Altitude in MSL can also be input, but this is converted to HAE by the avionics. HAE input is always preferred, as it avoids potential errors from rounding or truncation when converting between the two.

    AGM-88 HARM

    The AV-8B+ never carried the AGM-88. Wikipedia is wrong.
  16. I'm guessing there's some 1.11 going on. The anti-zhukov vitriol kind of gives it away...
  17. It's probably a quality/cost issue. For a grip like this you'd want to use a high strength plastic like fibreglass reinforced Nylon (the stuff you'll find in everything from power tools to Magpul Pmags). The disadvantage, from a production point of view, is that GF Nylon is quite abbrasive, and it wears out the injection moulds relatively quickly compared to other materials, increasing the production cost. Using die cast zinc is most likely a cheaper option.
  18. Is there any real evidence (i.e. not propaganda *cough*qaher313*cough*) that the IRIAF has ever fired any of the missiles they claim to have modded the F-14 to use? Ground mock-ups or captive carry tests prove nothing.
  19. To quote the brilliant B.O.M. guys: "Yes, boot, not trunk. It's not a tree or an elephant"
  20. A new shot of Beirut, with some cockpit blocking the view...
  21. I think they should just name the forum "DCS: F-(No, you can't have CFTs)-16".
  22. That sounds likely. The company is registered at a residential address in Lausanne, and the last time I checked there were other companies associated with the owner of TFC registered there.
  23. I would assume that he's referring to airports without either a PAR or ASR, not areas without radar surveillance of controlled airspace outside the terminal area.
  24. Do you work with hardware development according to ED-80/DO-254? I do. "Mil spec" is usually just a term used to describe the extended temperature range for components, compared to regular consumer and industrial temp ranges. That's not what I'm talking about. I can recommend reading a bit about rad hardening and SEU performance. There's more to it than fancy ceramic IC packages.
  25. Ehm, no. Aerospace grade components are expensive, usually several orders of magnitude more than their consumer grade counterparts. The GPS receiver alone probably costs more than your estimate, and the same goes for the three-axis ring laser gyro. These aren't $5 parts from AliExpress. And then you can start factoring in things like labor costs (manufacture, testing, logistics) etc etc. By all means, it's a seller's market, and Boeing are most likely making good money on the JDAM kits (otherwise they wouldn't be making them), but I the profit margins are nowhere near what you are suggesting.
