    main draw back of passive array antenna,you still need large central transmitter and a wave guide,with wave guide mean minus 7db,which means 70% reduction in range.
    in AESA,there’s no need for large central transmitter and wave guide to feed to RF into the antenna,result smaller antenna but with greater range.

    logic of Al-queda hitting the pentagon and WTC do justified?

    attack against pentagon and WTC cost the US,trillion of dollar.if the attack against serb civilian target was justify by the US, then al-queda can also justify there attack against the US,in there eye,war already exist between US “crusader” against the islamic world.

    thanks for the info,But for turbo popeye to achieve 1500 km range,and to be fitted inside submrine torpedo tube,the entire missile must undergoes massive redesign or even complete different kind of missile.

    in plain english,any attack by the US against iranian nuke could radicalised the iraqi shia.pushing iraq into iranian orbit.
    ironically , the only man could stand up to iranian ambition is right now being tried for war against humanity!

    kornet,right..

    Russian SADARM sensor fuse used “twin-color” Infran red imaging,possible that the Kornet fire-n-forget variant may adapt similiar sensor.But I am not sure,,even the russian never mention what kind of seeker it use,
