lets update the stats
SAAB JAS-39 "Gripen"
Aerospaceweb.org | Aircraft Museum - JAS 39 Gripen
*specs taken from dubai air show presentations and jf-17 brochures
*the conditions ,parameters under which climb rate / thrust to wt etc have been evaluated might not be standardised or fully disclosed
*All the values ive posted are from open published sources , so if there are confusions , its upto the companies to clear up
*..... however jft blk1 is not that obsolete as you suspect .. its better than gripenA & thats why i didnt use gripenA's specs.. I used a somewhat comparable block's specs
* we dont know the exact RCS of jft ... If jft was a canards fighters , some people wouldve jumped up and down saying it has greater rcs due to canards
* we dont know the wing loading of the fighter
[ a ground attack role fighter generally has a higher wing loading -
low wing loading is for performing at higher altitudes---multirole aircraft has to find a proper balance..]
* we dont know the AoA of jft -- f-18 has one of the highest values .. and jft would be comparable
[prominent lerx/strakes---> upto 50% increase in max lift , low/moderate swept wing---> better at lower speed performance , spin resistance etc ]
* methods of rcs reduction is a natural step forwards and hopefully would be employed in blk2 along with other gadgets we are reading about in the jft info pool
