It was a russian that came up with the stealth "equation"... Looks as if the ruskies have really learned how to exploit it.
Was pretty pessemistic until I saw the AESA radar and LE radar, plusplasma countermeasures - all pretty cutting edge.
Of course, until it goes up against AMRAAM, no-one will know. Fortunately at the mo, only the Indians and russians are getting them... for now.
