    I imagine that the B52+ F-16’s could be handled easily by the Rafale, especially with Meteor and AESA. The F-16 will be completely outclassed in both BVR and WVR. J-10b is prolly a closer match, but we really don’t know too much about it. I would still give Rafale the edge though.

    Does anyone know if the PAF F-16’s have HMS? What about the Indian Rafales?

    They jammed its communications, then used GPS spoofing to get it to land autonomously, apparently.

    Using knowledge gleaned from previous downed American drones and a technique proudly claimed by Iranian commanders in September, the Iranian specialists then reconfigured the drone’s GPS coordinates to make it land in Iran at what the drone thought was its actual home base in Afghanistan.

    1L222 Avtobaza covers 8000 – 17544 MHz which is X-band (I/J) or fighter radars.

    If we assume RQ-170 uses same datalinks as RQ-1 Predator, or Ku-band for SATCOM. Thats 12000 – 18000 MHz

    In other words it will not detect down-links from satellites to UAV.

    That still puts the vast frequency range of the satellite link within the Avtobaza’s capabilities.

    I’ve heard that Aviation Week is sometimes referred to as “Aviation Leak” in the government and industry for its tendency to accurately present privileged information.

    Actually he was quite right last time he mentioned it and is right again this time.

    Spheres are a comparitively AWFUL shape for low RCS, especially vs early warning systems. From a specular reflection standpoint they give a decent sized, uniform return no matter what angle they are being illuminated from.

    Surface waves are also able to travel right around a sphere and scatter back to the source radar which can lead to resonance and increase their RCS by over 4 times.

    You are largely correct that spheres are poor for RCS. However, surface traveling waves are not a problem, as they are on a perfect sphere, as the 101ksv is really only a half sphere, and surface waves will not travel uninterrupted around the object. That could still lead to edge diffraction issues, but that should be rectifiable using RAM, sawtoothing, and varying surface resistivity around the edge..

    What they don’t seem to grasp is that it is better to be involved in assembling / manufacturing / developing a high tech product like an aircraft than just to buy the complete product from a company. That’s an advantage, not a disadvantage.

    It’s an Ikea joke. Look at the box in the picture. 🙂

    Japan is worried about China. They felt snubbed after the US refused to offer them F-22. If F-35 is delayed that leaves the SH as the only US alternative.

    What do they do if the SH if found to not meet their requirements? They would then have no option but to go for TYphoon.

    If they really wanted to they could put out and RFI to Dassault.

    If they had similar T/W ratios, then why would the T-50 be significantly slower than the Gripen A/B/C/D? Are you talking about acceleration times or top speed (which is good enough for the T-50)?

    Drag. The Gripen actually has very low drag on account of its heavy area ruling.

    Libya does not have any integrated defence nor latest jamming pods on there aircraft. so it is moot point whether Rafale went there first or second in flat desert environment.

    And yet the USA and UK still sent in cruise missiles and Growlers to support their air assets, even after the Rafale had already softened things up through air strikes.

    UAE after getting used to extra thrust of F-16E is not so much impressed. infact Juppe visit is pretty empty handed.
    Either French politician sucks or Rafale sucks big time or both.

    The Indians apparently did not find the F-16E up to par for the MMRCA, whereas they found the Rafale to be acceptable. Undoubtedly kinematics and take off and climb performance at hot and high conditions (Leh for example) came into play here.

    THere is practically zero credibility behind extrathrust engine of M-88. After all India would have chosen it for LCA-MK2. as that aircraft is only coming online after 2015. so whats the point of order GE engine now? (does the contrat be signed?) and later another Kaveri-Snecma engine. when you cannot upthrust the engine in 5 years. It means your failure.

    The F414 is a significantly larger and heavier engine than the M88. So is the Kaveri. The LCA is a single engined aircraft. It has higher thrust per engine needs than the twin engined Rafale.

    Rafale poor showing in Libya may have prompted UAE to say it is unworkable. before they were giving benefit of doubt to this underpowered aircraft but not now.

    What are you talking about? The Rafale’s performance in Libya was nothing short of stunning. Rafales were the first aircraft on the scene, attacking protected ground targets without support from jamming aircraft or cruise missiles- no other aircraft did this AFAIK. During the Libyan conflict, they were shown to be capable of cruising without afterburner for an extended period of time at M=0.9 with large bomb loads and external tanks, and there is no reason to believe that this was even the full capacity of the engines.

    Really, it was likely the Libyan show that the Rafale put on that prompted the UAE to continue talks without the condition of an uprated engine.

    Sorry but Pakistan is no peer to India in military capability neither is India to China.

    Well, I agree that they are not equals by any means, but they are at least somewhat comparable- moreso than the USA to Iraq for example. I think what I’m getting at is that any confrontation in this region would likely be a conventional war. It wouldn’t be shock and awe.

    So, Rafale or EF?

    This guy says neither : :rolleyes:

    Good day all, Tay.

    Completely mirror imaging the US on India. India has to worry about conventional warfare with two potentially hostile countries on its border that are peers to it in terms of military capability. It does not need to worry about pacifying guerrillas in foolish military adventures on the other side of the world.

    That IS correct. Radome is transparent and its shape is not important. What is important is the shape and radar return of the non-transparent objects underneath the radome.

    FSS Radomes used by many modern fighters are only transparent at certain frequencies, so shape still matters.

    I think it is inaccurate that SPECTRA is developed by Thales North America. The only source for this that I’ve seen is airframer.com. I have never seen anything else to suggest this (let alone anything official). SPECTRA was developed by Thompson CSF, which was owned by the French state. That much is of no dispute. Later it became Thales.

    Given that many of SPECTRA’s capabilities are considered a state secret, I think that it is more likely that airframer.com made a mistake than that one of the Rafale’s most sensitive pieces of hardware was entrusted to an American company to be developed (especially that it was originally developed in France).

    Many things in aerospace manufacturing are globalized. The F-35 is loaded with European components (by design of course). Undoubtedly US components can likely be replaced with European components. However, this may come at an increased price for example.
