    I am not surprised you call that democracy.

    Take care of your country ( that is don’t do in sort that it becomes a ****hole ) , and I take care of mine.. bye

    It would appear The FN should not be overestimated either, although as one critic said it was not a ‘victory’ as they have done so well in the first round and have tripled the number of councillors.

    Well done to the French Voters who it seems have stepped back from allowing the FN to run regional governments, for now at least

    10 parties against 1, well done?

    Muslim maybe?

    The MICA can be rail-launched, so you don’t have to launch it upside down. Put the rail launchers on an extrendable arm, and make sure the missile’s seeker has a good fov when it is extracted from the bay. However an extendable arm would cost a significant amount.

    And of course you don’t want to have to fly upside down if you find yourself in a dogfight.

    The MICA could be a good choice, as it gives both WVR and BVR capability.

    For the rocket engine, I doubt it would be practical. The IR signature would be high and the structure would have to be reinforced. I doubt you would have much range with your hybrid propulsion.

    Stealth doesn’t mean invisibility. Even if your plane is smaller, that doesn’t mean that it will necessarily be more stealthy, it depends on the wavelength. A good ASEA radar is likely to detect your plane at significant range, say 30-40km, so you’re in trouble.

    Not giving it BVR capabilities would be a big waste for a stealth fighter. Just giving it a small radar and BVR missiles would maybe triple its effectiveness.

    Another problem is that if you want a WVR fighter, you have to make sure your WVR missiles have the maximum field of view for off boresight shots. So your bays have to be designed to extend the missiles and they have to be positionned in the right place ( the F-22 side bays for instance ). That will impact your design. If your plane doesn’t have really good off boresight capability it would be at a significant disadvantage.

    Also, in case the enemy uses heavy jamming, your AWACS and ground radars may be unable to give you the exact position of the target, so the pilot would only be limited to visual acquisition to try and find it, which would reduce the effectiveness of your plane.

    I don’t see the point of no BVR capability in a stealth plane, even if it is very small. The enemy planes would still be able to detect them before they can engage with their WVR missiles. I would concentrate more on a radar or IRST than maximum maneuvrability, and I would scrap the gun, too big and very unlikely to be used before the plane is shot down.

    Also, if it has no sensor at all, it wouldn’t be much better than a long range missile, or a mini UAV with a couple missiles remote controlled from ground radars or AWACS.

    What could maybe be worthwile is a mini supersonic UCAV, around 3 tons, similar in shape to a neuron, with 2 BVR missiles, and an IRST in front with 270 degrees fov. The IRST would be used to see through the jamming. Maybe 20 million each. Where you gain the most is on the operational cost vs a manned fighter. But of course a small UCAV would be much less capable that a real fighter.

    The UK is not part of Schengen, so ‘stopping’ it might prove a little difficult?

    Moggy

    Not possible… :stupid:

    It is estimated that 15000 AK-47s circulate in the french surburbs. The enemy is already inside the country and has enough weapons to slaughter tens of thousands of French.

    At least the UK doesn’t have open borders like us so weapons cannot enter the country easily. We have to stop Schengen immediately to control our borders! If it ends in civil war, it will be because of those ****tards who have been responsible of the immigration politicy for 50 years and because of those who have open our borders, ******* traitors!

    Do you realize that the F-35 does all of this with just 1 EOTS. The F-35 radar doesn’t betray its position. Why re-invent the wheel?

    I doubt the APG-81 could be used for that role in stealth mode. If you want to have a really good resolution to ID a target, you need sufficient radar power, so you probably can’t use an LPI mode, and you can’t survey the same amount of area in a short amount of time. The emission can be directional with an AESA radar, but even at that, if say you are surveying a road, and you stumble on a convoy, the enemy might well have radar receivers. Also if you want the look at for instance several roads on the side of the plane at the same time, you’d need side looking arrays. Side looking AESA arrays are more expensive than EO systems, they would cost maybe like 3 times more.

    From what I understand, I might be wrong…
