Internationally, I've always gotten the impression that the F/A-18 only wins customers who are put off by the cost of the F-15, but still need a little more than what the F-16 has to offer. Israel doesn't really fit into that bracket.
And how much of a export success the F18 really has been in all these years?
Basically the F18 is a design from the sixties (N-300), evolved in the P-530 cobra > YFF17
Introduced in 1983 as F18.
Exported Hornets, not that many numbers, to only seven countries. Plus one country the F18 E/F, only 24 till so far exported.
Australia, Canada, Switzerland, Finland, Spain, Kuwait, Malaysia
Expected Australia, the F18E/F will be a temporarily solution.
Switzerland: Gripen E/F. Canada: F35. Finland and Malaysia interested in the F35, Spain: F35B? Kuwait:?
Belgium:? (When they decide for replacement of the F16, probably the F35).
Brazil: Rafale ? (After the deal with India, Dassault probably has a very good change to win this deal)
Prospects, exporting the F18, are not that good.
