Meet the Saab JAS-39E Gripen: The World's Most Powerful Fighter Jet (You Never Heard Of)

JAS-39E Gripen arrived in Finland, for its flight evaluation as part of the HX challenge,
Finland's search, for its next fighter aircraft to augment, and slowly replace its fleet of FA-18C
slash D Hornets. Saab's offering, as some commentators have remarked, is the last Eurocanar
to be evaluated in the HX program. It also comes bundled with the Global I Airborne Early Warning
and Control, UAM, C, aircraft, which Saab markets as a force multiplier for the Gripen.
The complete systems, maintenance, and aircraft package that the Saab is selling has many
potential bonuses, for its potential selection as the HX aircraft, since Finland is looking for
substantial domestic repair capability, and possible technology transfer. If more systems
are sold, it could mean more technology is transferred, leading to further potential
development of Finnish industry. Despite the requirement in the HX program, Finnish industry
seems pretty lukewarm to the idea, of producing Gripen parts domestically. However, Saab has
pushed the idea pretty hard, stating that some Patria plants could even produce, and overhaul
engines domestically. Another interesting aspect of the Gripen offer is, the inclusion of dedicated
electronic warfare pods in addition to the Gripen's already supposedly formidable onboard
jamming capabilities. This, in Saab's words, is probably the most advanced EOS suite carried by
a fighter, which would make the Gripen a considerable asset for suppression or destruction
of enemy air defense, siege, dead missions. However, Boeing is including a dedicated and
proven electronic warfare aircraft, the EA-18G Growler in its HX program bid, so the JAS-39,
while possibly formidable, is outclassed in that aspect. Unfortunately for Saab, the Gripen didn't
actually fly in proper verification flights, though the Global Eye aircraft were able to, in its time
in Finland, leading to snarky media commentary that the Gripen couldn't fly in the snow. This is,
of course, not true. There were standard weather conditions for flights, and the snowy conditions
did not fit them, so the plane did not fly. Two more planes remain to be evaluated for the HX
challenge, Lockheed Martin's F-35A and Boeing's F-A-18E-F Super Hornet. The F-35A's evaluation
period is in mid-February. Both have their unique share of advantages and disadvantages,
the Super Hornet will likely be an easy transition for the Finnish Air Force,
which already operated legacy Hornets. But the F-35A has the advantage of low observability,
advanced datalink systems and its onboard optoelectronic packages. The F-35A is rumored
to be favored as it's truly a next-generation aircraft and has a growing European user community,
especially following the Polish purchase.
