Which fighter Aircraft is better F-35 vs. Gripen ?? Lets find Out !!

Air to ground:

Interdiction/Penetration:  The F-35 has always won this category.  As the only true “stealth” fighter available, it simply dominates here.  Other aircraft can be fitted with ECM or other radar evading techniques, the fact remains that the F-35 will be the hardest to detect.  Even if modern radar technology makes the JSF’s stealth less relevant, it will still have an advantage over less stealthy aircraft.
The Gripen does well for a non-stealthy aircraft.  Its small size and construction helps it reduce its RCS.  It also has an extremely small IR signature compared to other fighters in the segment.  Gripen Es will have sophisticated countermeasures and expendable decoys.  It will be the first aircraft to employ Gallium Nitride as a way to boost power to its electronic warfare systems.
For sneaking past enemy detection, the Gripen is good, but the F-35 is great.  Advantage:  F-35
Deep Strike:  The F-35 carries 50% more internal fuel than the CF-18.  Its proponents often bring up the fact that it has no need for external tanks.  What they neglect to mention is that the JSF cannot carry external tanks.  External tanks have been envisioned and even tested in the wind tunnel, but “separation issues” have scuttled the possibility of an extended range F-35 for the foreseeable future.  The JSF has a range of 2,220km.  It should have the capability of mounting the 1,000km+ range AGM-158B JASSM-ER ALCM, however.  This would greatly enhance its effective strike range.
Older Gripens have a reputation for being a short-ranged fighter.  This has been addressed with a vengeance in the Gripen E/F models.  Saab increased internal fuel capacity by 40%.  They have also developed 50% larger external fuel tanks.  With these improvements, the Gripen E is now capable of traveling over 4,000km between fill-ups.  The Gripen lacks compatibility with the JASSM-ER, but it does make do with the 500km+ range Taurus KEPD 350.
Both aircraft will have their range reduced somewhat by carrying external stores.  Big missiles (for both) and big tanks (for the Gripen) add a lot of weight and drag.  Things get even fuzzier when you consider that the F-35 may not even get the JASSM anytime soon, merely “eventually”.  Given the Gripen’s ease of weapon integration, the JASSM-ER certainly does not seem out of the question for it.
Considering how fuzzy this category is, it could go either way.  If the F-35 were to get external tanks to go alongside the JASSM-ER, it wins.  If the Gripen gets the JASSM-ER, it wins.  As it stands now, the difference in ranges is not enough to declare either aircraft the victor here.  Advantage:  Tie
Payload:  The F-35 has 4 internal hardpoints located inside its weapon bays.  The wings can mount an additional 3 hardpoints each for a total of 10.  Altogether, the JSF can carry an impressive 18,000lbs worth of ordinance.  It is limited somewhat, however, as the internal bays are limited in their size and shape.  Two of the internal pylons are for AMRAAMs only, and larger missiles (like the JASSM-ER) will need to be mounted on the wings.
The Gripen has just as many pylons as the F-35, but its payload is limited to a little over 15,000 pounds.  An impressive number, but not enough to compare to the F-15Es and Rafales of the world.
Both aircraft are single engine, but the F-35 uses a much larger single engine.  This makes for a larger aircraft capable of lugging a heavier payload.  Advantage:  F-35
Close air support:  Much has been said about the A-10s retirement in favor of the JSF taking over its close-air-support role.  So much, that it does not need repeating here.  What does need to be said is that the F-35 is a fragile aircraft, incapable of withstanding small arms fire.  In order to perform close-air-support, it flies high above the battlefield and uses its EOTS to find targets.  When a pilot cannot put their own eyes on a “danger close” target, bad things can happen.
While the Gripen is no A-10, it does have some impressive close-air-supprt capabilities.  Being a close-coupled-canard design gives it impressive low-speed handling.  The Gripen also tucks away a heat exchanger and exhaust vent right behind the cockpit.  This keeps the aircraft’s IR signature down and improves survivability against MANPADS.  The Gripen is also capable of operating from austere conditions, allowing it to be based much closer to the action.  It even has an impressive close-air-support weapon selection, which includes guided bombs, rocket pods, and the Brimstone missile.
For close air support, the Gripen is certainly an excellent choice.  Unlike some newer aircraft, it can actually put the “close” in “close-air-support”.  Better still, it has a plethora of “low collateral damage” weapons to choose from.  Advantage:  Gripen
Air to ground winner:  Both aircraft promise ground attack capability with their very designation.  Joint STRIKE Fighter for the F-35.  Jakt (air-to-air), Attack (air-to-surface), and Spaning (reconnaissance) for the JAS 39 Gripen.  The JSF places more of a priority on the strike role, however.  Its ability to penetrate enemy defenses and carry more bombs than the Gripen give it the win here…  But barely.  Something as simple as JASSM-ER integration with the Gripen would give the Saab a clear advantage in the “Deep Strike” category and tie things up.  Until then, the F-35 comes out on top here.  Winner:  F-35

Air to air:

First look, first kill:  With its stealthy shape and advanced sensors, the F-35 can dash through the air akin to some sort of “sky ninja”, taking its opponents out unseen like a shadow in the night.  That is what the JSF marketing seems to imply, anyway.  The truth is that the F-35 has a slightly-above-average radar (the APG-81) and the equivalent to an IRST (DAS) built into a airframe that just so happens to offer a smaller RCS than most.  It is still quite visible in the IR spectrum.
With no faceted “stealth” design, the Gripen’s RCS is larger than the F-35’s.   The Gripen likely has a smaller IR signature, however, due to its smaller engine and less draggy shape (drag=friction=heat).  As for radar, the Gripen’s ES-05 Raven AESA array is roughly the same size as the F-35’s but it has a swivel plate than enables a much wider field of view.  The Gripen is also equipped with an IRST.
The F-35 will likely be the first to see its opponent thanks to its stealthy shape, good radar, and DAS. This does not guarantee victory, however, as the JSF needs to get in fairly close in order to shoot its AMRAAM.  The F-35 pilot would need to weigh the risks long distance missile shot with a reduced probability of kill or getting in close and risking detection.  Advantage:  F-35
Beyond Visual Range:  The F-35 carries the well known AIM-120D AMRAAM inside its weapon bays.  While “the specs” list a range of over 180km, the actual useful range is much lower.  Especially against an opponent with RWR (radar warning receivers), a skilled pilot, and countermeasures.  If the missile is fired too far away, it can be easily outmaneuvered.  If the F-35 gets too close, it can be detected by IRST or possible even radar.  Complicating matters is the AMRAAM’s actual combat record.  Since its adoption, the AMRAAM has shown a pK (probability of kill) of less than 50%.  Those targets had no countermeasures, were not maneuvering, nor were they even engaging the firing aircraft.  One was a friendly fire incident.
If the JSF pilot wants a realistic chance of bringing down the Gripen, they will have to get uncomfortably close to being detected.  If the Gripen’s pivoting AESA radar, IRST, and radar warning receivers (RWR) pick up the F-35’s approach…  All bets are off.  With is ability to supercruise and a faster dash, the Gripen has the speed to outrun the F-35.  It also carries the MBDA Meteor missile, which has a much larger “no escape zone”.
Getting the drop on the enemy is a distinct advantage, but it does no good if one cannot follow through.  The F-35 is severely hampered by its slower speed and shorter ranged AMRAAM.  Most likely, the best it can hope for is one good shot (with a pK of less than 50%).  As soon as the Gripen detects an F-35, it has the advantage.  Its pilot has the choice of either engaging with its longer range Meteors, or closing the distance to the point where the JSF’s reduced RCS is no longer relevant.  Advantage:  Gripen
Within Visual Range:  The F-35’s stealth advantage completely disappears in a WVR scenario.  Its big, hot engine is easily visible to IRSTs and heat-seeking missiles.  The JSF does have the most advanced helmet mounted display (HMD) on the market and its DAS (distributed aperture system) gives it a true 360° view around the aircraft.  The real kicker would be whether or not the F-35 is carrying WVR missiles.  When in “stealth mode” the JSF carries 2-4 AMRAAMs internally.  Any IR guided missiles need to be mounted on stealth-robbing external pylons.  Yes, radar-guided AMRAAMs can be used at WVR ranges, but IR guided missiles (like the AIM-9X Sidewinder) have a higher probability of kill (pK) as well as faster “lock-on” times.
Meanwhile, the Gripen will almost always be carrying at least two wingtip mounted IR missiles.  These could be Sidewinders, IRIS-Ts, ASRAAMs, Python 4/5s, or even the Brazilian A-Darter.  These can be fired with the assistance of IRST and HMD, much like the F-35.  The Gripen also happens to be quicker and more agile than the F-35 thanks to superior thrust-to-weight and wing loading numbers.  Its smaller IR signature gives it an advantage here.
This one is no contest.  Even if the F-35 is carrying IR-guided WVR missiles, it would be at a disadvantage against the Gripen.  Advantage:  Gripen
Dogfight:  When specifications were being written for the Joint Strike Fighter, planners must have forgotten the lessons learned over Vietnam.  The dogfight was considered “obsolete” thanks to the age of guided missiles.  American pilots soon realized that guided missiles did not work as advertised and that a gun is very much a necessity.  The F-35A has a 25mm gun, but the B and C models do not (a gun pod is being planned).  The JSF also suffers from poor visibility and is unlikely to withstand much damage, thanks to the removal of fire suppression gear to save weight.
The Gripen is equipped with a 27mm cannon on all single seat models.  It is an excellent performer at low speeds and high angles of attack.  Its smaller size makes it a harder target.  It does lack a true “bubble” canopy, but the only blind spots are the frame and at the very rear where the pilot’s head cannot turn anyway.  The single, vertical tail also blocks the pilots view far less than twin canted tails do.
In a dogfight between an F-35 and a Gripen, it really is hard to imagine the JSF coming out ahead.  The F-35 pilot will want to avoid close encounters of any sort.  Advantage:  Gripen
Air to air winner:  In a hypothetical aerial engagement between an F-35 and a Gripen, the F-35’s best chance is to catch the Gripen unawares and end things quick.  This is easier said than done, as it would require getting uncomfortably close.  Anything other than a sneak attack favors the Saab.  It is quicker, more agile, and fields a superior choice in missiles.  Winner:  Gripen


Versatility:  As much criticism as the F-35 receives, few have complained about its lack of versatility.  Quite the opposite.  The JSF’s very raison d’être is to be whatever you need it to be.  It can perform air-superiority, strike, reconnaissance, and plenty of other duties.  If needed, there are STOVL and CATOBAR capable versions available.  It lacks a two-seater version, however, an omission that limits its use for training and high-workload missions.  The F-35 is also quite proprietary in its design.  Users who wish to add their own weapons or perform modifications to the hardware or software need to do so with the Pentagon’s and Lockheed Martin’s permission.
The Gripen is equally comfortable performing air-superiority, strike, or reconnaissance missions.  It lacks a STOVL version, but aCATOBAR capable “Gripen-M” seems increasingly likely.  The Gripen  is also much more “open source”, offering full technology transfer and easier weapon integration.
STOVL has its uses, but the strategic value of placing multimillion-dollar fighter jets in the front lines is dubious.  Given real-life conditions, it is much more practical to have access to a two-seater aircraft for training and the like.  It may not seem as glamorous, but most air forces have no need for STOVL or CATOBAR capability.  This gives the Gripen more “real world” versatility.  Advantage:  Gripen
Logistics:  Even if the F-35 does not sell at original estimates, it will be built in the thousands and see use all over the world.  Parts should be plentiful and there should be no lack of qualified technicians.  The aircraft’s stealth characteristics complicate matters somewhat, however, as it requires additional security and other special considerations.  Australian documents suggest that the F-35’s radar absorbent skin can be damaged if left in direct sunlight too long.  Cold weather testing has yet to be done.  The F-35A also requires at least 8,000 feet (preferably 10,000) of runway to take off and land safely.  Austere airfields need not apply.
While the Gripen will never likely reach JSF-like sales, it does see service around the world.  It is especially popular with smaller air forces on a fixed budget.  Weather conditions do not seem to be a factor, as it sees use everywhere from Sweden’s arctic to Thailand.  Maintenance is made easier by easy to access systems utilizing plenty of “off-the-shelf” parts.  A team of six can refuel and rearm a Gripen within 10 minutes.  Not only that, but the Gripen can operate from a mere 2,400 feet of straight highway, and get serviced from a truck.  It is the farthest thing from a “hanger queen” a modern fighter can get.
The F-35 may find itself in service all over the world, but it will likely be a challenge to keep up with its needs.  The Gripen, on the other hand, seems ready to go anywhere, anytime.  Advantage:  Gripen
Versatility/Logistics winner:  There is little doubt that the Gripen would be much easier to live with.    Its ability to operate from austere conditions is a huge benefit for air forces on a budget.  For those nations that have no use for CATOBAR or STOVL capability, the Saab makes an easy fit.  There may be a CATOBAR version soon.  The F-35 has STOVL capability, but lacks a two-seater version and the F-35A needs a full service airbase.  Winner:  Gripen

Final Score:

Air to ground:  F-35 = 3  –  Gripen = 2
Air to air:  F-35 = 1  –  Gripen = 3
Flexibility/Logistics:  F-35 = 0  –  Gripen = 2
Final result:  F-35 = 4  –  Gripen = 7
