Saab have always made quirky and interesting planes, it seems their latest effort might be their best, for a cheaper, good alternative to the F35 or others the Gripen apparently takes some beating, very cleverly aimed and marketed it seems. and for such a small country to continually make stuff of that quality is amazing, yes the Draken and Viggen were not a sales success but the Gripen seems to be.

I believe that the Viggen was designed to the same concept as the Jaguar & Harrier, i.e. a cold war scenario in which they would operate from roads/rough fields after their airfields were destroyed.

The SwAFHF do this as part of their Viggen display you can see the nose wheel pitching down under the heavy deceleration

Crazy. Wonder how they manage the heat from the brakes. Light enough to not get them to bursting into flame?

Most of the silly braking is done with a sort of clamshell reverse thrust system, possibly the finest example ever fitted to a fight plane.

That is a great photo. You can see the heat haze from the reversed thrust coming well forward of the fin.

A lot of the work is done by the reverse thrust system, and the Viggen's not as big a plane as it looks.

Basically as it lands, the Tornado had a very much more basic system, a clamshell shaped sort of like three petals comes across the nozzle on the Saab, the pilot engages the reverse thrust aspect and the vent just forward of the rear end is where the gas escapes, the Tornado had clamshells that just popped out of the rear fuselage and covered the nozzles, you could also tell it was there as the back of a well used Tonka was black with soot!!

I don't know if that many other planes used a similar system militarily, just about all modern commercial aircraft do even smaller biz jets.
