JAS 39 Gripen vs Sukhoi Su-27

1. Here JAS 39 Gripen is armed with AIM-120D AMRAAM while Raphael Dassault and Eurofighter both are armed with the superior Meteor system – if anything it should be the opposite since JAS Gripen so far is the only aircraft fully tested and integrated the system.

The data here is also for the original JAS 39 Gripen, the most common version today is JAS 39 C which can carry more load and has a more powerful thrust / weight ratio. (Yet a more upgraded version will be built with Brazil, JAS 39 NG).

2. JAS-39 should be compared with F-16 or J-10, while SU-27 should be compared with F-15.

3. In dogfight probably Su-27 is winner, but in Beyond Visual Range fighet Gripen should have adventage. It has better radar and technology, and also new versions use MBDA Meteor that is best Air-to-Air missile for maneuverable targets, lot better than American AIM-120 AMRAAM or Russian R77 Vympel. Also for medium range Gripen use MBDA MICA that is also good against maneuverable targets and it is fire-and-forget short and medium-range missile .
