#1 is a tie between:
Harrier (see above post) and S-2 Tracker:
Argentina
Australia
Brazil
Canada
Netherlands
United States
(and many land-based)

#3 A-4 Skyhawk:
Argentina
Australia
Brazil
United States
(and 6 other nations land-based)

Other candidates?

I think India also operated SkyHawks in its carrier Vikrant

Read my statement again. I Said Now
Russia after Cold has not built a new nuclear reactor for itself nor it has built new nuclear weopons large scale.
and u can see that from there budget figures for nuclear industry and defense budget.
just one or two years they have started tests on more long range weopons.
and that is one of the reasons that Iran carries 60s and 70s era US weopons and couldnot pay for S-300 and new Flankers because they spent too much on Nuke/missile industry.

yaaa..The Topol M and Bulava missiles were made by iran :diablo:

Politicians are rarely held in high regard for honesty in any country

True…But in Russia (if the report is correct) it seems that it is an extreme case..I thought Putin enjoyed much more popularity.

“Overwing launch rails were originally fitted, at least to the single-seaters, for carriage of the Matra Magic AAM,”

Exactly what part of the above sentence do you have a problem understanding?

originally MIGHT mean that during their first batch induction(which you say is in 77) or second batch and so on..The date of actual induction of such a system is not explicitily stated..
I am NOT saying that Omani jags didnt have overwing pylons, i just mean to say that the article does not mentio clearly which year it was inducted…

Was Magic available in 1977 for Omanis?

” All Omani Jaguars were all painted in a brown / sand desert camouflage scheme. Overwing launch rails were originally fitted, at least to the single-seaters, for carriage of the Matra Magic AAM, but for some obscure reason the Omanis decided to switch to carrying AIM-9P Sidewinders on the outboard underwing pylons. Oman actually assigned its Jaguars an air-defense role. ”

Happy!? Or let me guess, your ASTE developed the Omani Jags as well!? 😉

Omans Jags were delivered in 1977, and they were using launch rails, so lets end this stupid debate here and now, as frankly lots of users here would get more credit if they just admited they may be wrong and for once their countries claims are wrong, there is no shame in it….

The date of introduction of overhead pylons is not given..it may be a later improvisation

Austin,
The role of mirages as nuclear weapon delivery platforms is a very good point. But then do we need 125 of them?…

ink, with all respect, you can read everything what you want, but the berkut desing have nothing to do with the flanker (maybe only that huge nose 😀 ), about the flankrum :p lerx design, is completely diferent of the berkut-f18 lerxs

well that was an personal opinion, but i think that internal bay concept is an waste of time and resources, simpler is better.

If there is no internal bay then the aircraft will not be stealthy. So what is the point in having a new aircraft ?. A new non-stealthy plane is 4th gen only..Perhaps 4.999 but still 4th gen.

There is no point in making a new aircraft if its not going to be stealthy..The Su 3x series with TVC is as maneouverable as F22 and the load capacity and range are also good..Its better to add new avionics to them than develop a new non-stealthy plane.
