    yeah Crobato more excuses, so them tell me for what is the Helmet mounted sight? the Python V has +110 and -110 degrees of off bored sight, the Python IV it has +90 and -90 degrees only the head seeker allows it to have twice the range of the PL-9, the PL-9 has a more limited seeker and even with Helmet mounted sight will still be in disadavantage.

    The Derby also is used as a short range missile it is like the Mica, so the still gives close combat capability.

    the 360 degrees of the Python V are still a fact they can use against the J-10.

    My god, what is the helmet sight for? Apparently even the basics escape hyou. In the first place, it is used to allow the pilot to see and target symbology outside of the field of view of HUD. The radar’s field of view is actually much greater than the HUD’s. Even in BVR, an HMS has an advantage because the radar’s FOV is more than the HUD’s so you can lock to a target outside of the HUD’s view.

    If you have 60 degrees boresight how much of an advantage it is over 90 deg boresight, huh? Just a slight twist of the head in real world terms. Given the way the pilot is tied down to his hardness, the large size and inconvenience of the HMS, its not even easy to turn your neck a full 90 degrees in order to target something that is flying perpendicular to you. This has limited and debatable value, given that it is important for the pilot to maintain both his view of the enemy and that of his instruments at the same time.

    Then what is the point of having boresight over 90 degs? You are not like a possessed Linda Blair who can twist her head around completely.

    Even if you see a plane through your eyes, what makes you think its a friendly or foe? Human judgment when it comes to friend or foe identification has proven to be quite historically dubious in the face of blue on blue accidents. Hence you have to rely on the plane’s IFF to be absolutely sure, you’re not shooting down a comrade. So you have to rely on your nose IFF, and that means the target has to be in the view point of your nose, especially in the upper part of it (note the antennas sticking on top of the nose). This means you cannot fully exploit all that FOV without getting into the IFF’s FOV first. This might work within 30 or 60 degrees off the bore of your nose, but right at the side, at 90 deg? I kind of doubt that.

    Statements like what you just said on the Derby showed your complete ignorance on missiles, because what you are saying is pretty much standard and universal with all BVR missiles SARH or ARH. Even the Sparrow has close combat modes.

    By the way, if you are in a position that you would think you can launch a rear ward missile to an opponent in the rear, in the first place, you would already be dead, because he would have launched his missiles first the moment he got you on his nose.

    Talk about selling things you really don’t need.

    Crobato,
    A question here. What if a fighter knows for a fact it is the only one dealing with bunch of hostiles and lets say for the kicks can even see a couple on its tail in the mirror, wouldn’t it be a useful capability to shoot the missile with a 360 degree angle and let it lock on to *anything* in the rear(with the excepton of its own rear :p ) ?

    No. You have a good chance of hitting your wingman first. If you are familiar a bit with two plane element tactics, you would know there is a good chance your wingman is going to be within the rear sphere of your plane. Besides, missiles will not launch without authorization from your IFF. In other words, to launch a missile blind is not permitted by the plane’s systems in the first place, which has many checks.

    Trying to obscure the issue here, huh?

    How did the Derby came here? The Derby is a radar guided missile. That put it in the same class as the AMRAAM, MICA, R-77, SD-10, and all such missiles have datalinked midphase guidance.

    Your continuous hype of the Python V having 360 coverage continue to tell me you have no idea what IFF is all about until now. You cannot shoot what you cannot identify properly, as missiles require authorization via IFF. Every LOAL missile, like the radar guided ones above have 360 degree coverage by using the same token.

    The Python V and Derby do use Data link

    The Derby does, being a radar guided missile. But IR misisles do not use datalinks. Even with LOAL, they have to be cued and preprogrammed to the direction of the target before the missile is launched.

    yeah yeah Crobato more excuses of you, if they are Russiasn sources blame it on the sources if they are western sources blame it on the sources yeah, yeah.

    More bull from you. Russia and China are opposed to tough economic sanctions but it does not mean they are not opposed to military sanctions which they have all agreed upon already. What they are opposed is taking it further without negotiation.

    The Python V uses data link to achieve 360 deg engagement envelope and its head seeker has a +110deg or -110 deg off bore sight cabaility, compared to the PL-9 it is twice the off bore capability.
    The Python IV even has +90deg or -90deg of bored capability

    You really full of bull. It says it uses Link 16, but the problem of Link 16 is that it is far too big and complicated to be physically installed in any missile. The missile itself does not have Link 16 but it uses the Link 16 through the plane before it it is launched to cue it to the target’s direction. Once it is launched, it is completely autonomous.

    If you have to use a datalink, that means you have to rely on other planes. It means some other plane has to use its radar to IFF the target. It also means the link can be jammed as well.

    No matter what you cannot escape the fact that you have to put your target into your radar’s point of view, then IFF it. In effect, your effective boresight is no bigger than your own radar’s field of view, which is around 60 degrees.

    It is not the sensor of the AAM alone, but the datalink and the related software via the bus-system. Every mission is digitalisized before take-off and can be updated during flight. Over Syria a F-16I will not face a Mirage 2000. Over Egypt it will not face a MiG-25 a.s.o..
    Modern AAMs are flying computers today. A picture from one sensor-head can be shared with others linked f.e.

    There is no IR missile today that has a datalink. If images are captured then transmitted to other planes via datalink, that is when the missile has not departed the wing yet, and you are routing this information via datalink.

    Yeah crobato yeah yeah the israelies do not use lock on technologies, the missile is designed to lock on and kill the target, besides the Israeli aircraft have electronic systems that allows them to tell apart friend and foe fighters, do you know what is a IFF? this allows them to know who is out there.

    Israel usually also fits Israeli equipment to the F-16s so basicly they are not the same to the F-16s of Egypt or Turkey.

    The Targeting system is in charge of locking on the Python V or Python IV either with the helmet mounted sight or radar, so pretty much an Israeli F-16 pilot will distinguish very well a J-10 from an Israeli F-16 and will lock on the Python V or IV into the J-10.

    read about the Sufa

    The F-16I is based on an advanced F-16 Block 52 aircraft. The Israeli version has integrated several new systems, developed and produced in Israel, required by the IAF, to maintain and enhance its operational capability. Despite the inclusion of many additional systems, the empty weight of the aircraft was maintained at the level of current Israeli Block 40 (Barak) F-16s. The “diet” included the use of lightweight materials, as well as the use of advanced avionics that offer considerable saving in weight and space.

    The Sufa version of the F-16 Block 52 has a distinctive dorsal avionics compartment that accommodates all of the systems of the single-seat model as well as some special mission equipment and additional chaff/flare dispensers. The Israeli model is powered by the Pratt & Whitney F110-PW-229 Increased Performance Engine (IPE) engine develops over 29,000 lbs of thrust but weighs only 3,740 lbs. It incorporates modern turbine materials, cooling management techniques, compressor aerodynamics and electronic controls – many of them derived from F-119 and F-135 engines used in the new F-22 Raptor and JSF. The Advanced Block 52 aircraft use the Normal Shock Inlet (also known as the small mouth inlet).

    Cockpit:
    The Israeli F-16I cockpit features a helmet-mounted cueing system, color multifunction displays and recording equipment, cockpit lighting and external strip lighting compatible with night vision goggles, and large-capacity data transfer sets. Cockpit displays are driven by the Integrated color display processor (ICDP) developed by Elbit Systems, which drives the six multifunction color liquid crystal displays with 484×484 pixel resolution, built by Astronautics CA. HUDs are delivered by BAE Systems (initial 18-25) and El-OP (77-84). For the first time, the company embedded a digital map system and digital terrain flight algorithms into the ICDP computer. Such integration has saved considerable weight, wiring and logistical and technical support, previously required for separate systems. The Inertial Terrain Aided (RITA) system, developed by RAFAEL, uses proprietary algorithms based on accurate terrain reference navigation that improve low-level flight safety, and enable terrain following flight in all weather conditions, day or night and improve flight safety by avoiding ground collision. The aircraft is also equipped with a LANTIRN navigation pod, which enables automatic terrain following flight, utilizing a combination of forward looking imager and TF radar. This system enables the both crew members to fly safely at low altitude, as they were flying on “autopilot”, and concentrate on the employment of mission system and weapons. The fully missionized rear cockpit is used for navigation and Weapon Systems Operation (WSO).

    Each cockpit has three displays and Head Up Display (HUD). Color coding is designed to match specific information, in different operational modes, to emphasize the information most important at every phase of the mission. All cockpit lighting, including the color displays, are designed to work with night vision systems. The tandem cockpit utilizes two fully functional positions for the pilot and weapon systems operator and navigator, both are equipped with the DASH-IV helmet mounted display and sight, developed by VCI Inc, a Rockwell-Collins / Elbit Systems Joint Venture which is also developing the new JHMCS helmets for the USAF and US Navy. The helmet display also provides critical flight and target information to the pilot — similar to a head-up display, but in any direction the pilot looks. DASH IV is a fourth generation of the DASH system, of which 500 are already in service. The new system offers several advantages compared to previous models, such the addition of a video camera that can record the pilot’s view to the mission debriefing system, more accurate line-of-sight tracking, etc. The system offers improved tracking accuracy and a miniature helmet mounted video camera that records the pilot’s line of sight view.

    Core Avionics Systems
    Another improvement over previous F-16 versions was introduced in the core avionics, which utilizes the General Avionics Computer (GAC) delivered by EFW, a division of Elbit Systems. This computer benefits from technology advances including increased processing speeds and memory capacity, by the using off-the-shelf technology, which improves supportability. The aircraft is equipped with a high capacity, ultra-fast network based on a fiber-channel backbone, which links all avionics modules, external stores and sensors into a unified, high capacity multi-channel network. Utilizing a high capacity (1 gigabyte) switch, the FiberChannel runs data streams over five channels with standards based protocols such as 1553 and 1790.

    The navigation equipment is based on a 7 channel GPS and ring-laser Inertial Navigation System (INS), an integration of systems produced by Honeywell, Raytheon and General Dynamics. The TACAN is provided by Rockwell, which also provides the ARC-217 HF radio. BAE Systems is providing the ILS system and an advanced IFF transponder/interrogator. which improves the operation of the aircraft beyond visual range, and enable safe employment of long range A/A missiles. The communications equipment is based on an integrated voice/data system, that incorporates RAFAEL’s Green Radio, a localized and improved version of the Rockwell Collins ARC-210 VHF/UHF radio, equipped with a data modem, and an advanced data-link system, produced by IAI/MLM. These classified systems are believed to be more advanced to Link 16, offer integrated, secured and jam-resistant communications was designed to provide instantaneous high quality, high capacity communication between surface and air elements.

    The aircraft is also equipped with an advanced data recorder, Advanced Data Transfer Equipment / Digital Video Recording (ADTE/DVR) developed and produced by Smiths Aerospace. The system uses a 15 gigabyte memory cartridge to store the entire flight records. The system records and time-stamps three video and databus channels, including video (HUD, helmet view, sensor view etc), audio (radio, intercom), avionics and sensor data (radar, digital map and flight data systems.) 3 digital video channels. A special mission debriefing system (SIMNET), designed by RADA is used to extract the data and present it for post mission debriefing and analysis.

    And after all that shameless hyping of marketing material of yours, regardless whether you use an HMS or not, everything still boils down to doing IFF, and that means bearing down your radar on the target since it is the radar that will still do the IFF interrogation. Which means you cannot just fire your missile to the back and expect to hit a hostile, not your wingman.

    It just seems to me that you try to cover up your technical ignorance by displaying and posting large amounts of marketing info without really trying to understand and discriminate what really is in it.

    actually, looking at the image of the IIR seeker posted by Flogger, the F-16 can be clearly distinguished and so would the J-10..

    Really I kind of doubt that, especially against a two seater J-10S, since the F-16’s image is that of the two seater F-16C with the spineback. The J-10S also has a spineback. And these kinds of images are taken in ideal conditions, without consideration in the real world of atmospheric refraction, diffraction and attenuation. And do tell me what kind of image do you get if the target is like 20km away. And what if the targets are coming head on to you?

    Regardless, its not a missile’s job to do IFF. If a missile is specifically programmed not to engage an F-16 for example, you will get into a major problem with an F-16 vs. F-16 fight, like Israeli F-16s vs. Arab F-16s, and the Arabs have quite a number of F-16s on their own. There are also aircraft there that can be either friend or foe depending on their actual allegiance, like Mirage 2000s. Program your missile not to engage Typhoons for example, and what if the Arabs went and bought Typhoons, and you find yourself facing the type. Then there is the nightmare scenarios when a friendly plane goes rogue, carrying a bomb, even a nuke, that can be potentially be used against your cities. You need that final option to destroy a rogue plane.

    Python 4’s seeker is not that far off from the PL-8B’s seeker. Again, you’re talking of cryogenically cooled seeker using multispectral wave bands, which leads you to suspect if there was any more Israeli influence that goes on to the improved PL-8B seeker (used on the PL-9C).

    As for your Python 5 seeker imagery, you can’t tell an F-16 from a J-10 with that. Since you (Flogger) cannot tell the difference between a Lavi and a J-10, a microcomputer with less intelligence than a cockroach isn’t going to do any better.

    it is not over rate it is only a way you want to claim the J-10 is not inferior in weaponry, the Python V and Python IV have better discrimination than earlier missiles, the Python IV is claimed that within 5km no target will scape that is the claimed no scape zone.

    LOL. They discriminate between plane vs. decoy. Not plane vs. plane. Missiles do not do friend or foe idenification.

    All what you say about identification also applies to the PL-9 or any other missile, but the Python V or Python IV have off bore sights of 90 deg and in the Python V after launch engagement capability of 360 deg.

    And its all useless unless you can IFF your target first. That means putting your target into the plane’s radar bore first.

    BS. The AIM-9X or Python V maybe better than the PL-8B, but it does not mean its a guarantee. Only an idiot thinks things are determined in black and white and being better is a guarantee. Bull. It does not stop the PL-8B from being a threat, especially if your plane is so heavily wing loaded you’re not very agile. That’s like claiming my 9mm pistol is better than your 9mm pistol, but that does not guarantee you will win the fight.

    The figure Sinodefence took was originally from a brochure that was selling the PL-9C as a ***SAM***. Read the ad. it says 8km for ground to air. You obviously lack the intelligence to discern and discriminate information.

    And you actually think having 60, 90, or 180 or 360 degrees is that important? Overrated.

    As a matter of fact, in Bekaa valley, even with a 30 deg off boresight, Israeli pilots were firing their Python 3s at dead center because they are afraid that the missile can lock into anything else including a friendly.

    Thus, its all pretty useless until you can clearly identify the target as foe or friendly before you fire. That still means you have to put your target in your radar’s field of view for proper IFF, either cooperatively or non cooperatively. Having an all around aspect also greatly increases the chances you may target your own wingman in the process, if you want to fire blind without determining who EXACTLY the missile is locking onto.

    Thus in practice, your’s missile’s effective off boresight during combat isn’t any better than your radar’s field of view.

    As for the service rates it was probably bad in the beginning. But certainly not now. As a matter of fact, we can tell from pictures of very recent vintage, that the Su-27s are still there and working, especially with the 19th Division, where the first 24 Su-27s now went. As a matter of fact, the 19th Division had a major wargaming exercise against the J-10s of the 44th Division last December. There are ways to distinguish the original Su-27s from the J-11s, and there are ways to date the era of the pictures by the way the planes are marked,.

    Tracking and interception algorhythms like the one on the PYthon 4 are not hard to develop either. In fact, its quite obvious missiles should have them, and there is no need to advertise the obvious.
