ASaC7 is not bad by all accounts, although it would be better if it could stay up higher and longer. And to add to the point on E-2D - it is so intimately involved with the US Navy way of doing business that it might be ill matched for anyone else's needs. (Note the fact that attempts to glue the E-2 radar on to other platforms have not appealed on the export market, nor generally has the E-2.)
