It was already the case before F35I.

Two Air Force F-35s Make Rapid Deployment To Jordan To Get Closer To Syria Action

Air Force F-35As have been conducting a variety of combat operations, including airstrikes, against ISIS in Syria, as well as Iraq, for months now. However, the rapid deployment to Jordan is likely linked, at least in part, to the continued U.S. presence at a garrison near the city of At Tanf, which lies along a major highway in the region and is situated fewer than 15 miles from both the Iraqi and Jordanian borders. U.S.-backed Syrian forces and American troops, primarily special operations forces, occupy this highly strategic location.

Source please....
At least Rafale is not so limited...


"An issue that risks damage to the F-35’s tail section if the aircraft needs to maintain supersonic speeds is not worth fixing and will instead be addressed by changing the operating parameters :pound:, the F-35 Joint Program Office told Defense News in a statement Friday.
The deficiency, first reported by Defense News in 2019, means that at extremely high altitudes, the U.S. Navy’s and Marine Corps’ versions of the F-35 jet can only fly at supersonic speeds for short bursts of time before there is a risk of structural damage and loss of stealth capability.
The problem may make it impossible for the Navy’s F-35C to conduct supersonic intercepts."

Five F-35 issues have been downgraded, but they remain unsolved



What a easy solution ! you can't solve a problem, so you downgrad it !

In french we called that "mettre la poussière sous le tapis" ( put the dust under the carpet )

@Manticore : the new US technic to solve problems?

It's a festival !


The pentagone solved 5 issues but found 4 new !


I'm sure that Switzerland and Finland will like to read that !

Seems like it only happens at the extreme edge of high altitude envelope of around 65K feet, also to use afterburner more than 80 seconds is burning through fuel like crazy. This is hardly ever used in real life. Moreso, going supersonic means they loose their stealthiness.

They say that B and C variant can only fly to mach1.3 forty seconds, and mach 1.2 the double (80 sec)
They say the full reheat can't be used more than 1 minute.
They say that beyond 20° AoA the plane is unstable.

They say the limitations are probably the same for A variant, but as the plane is on ashore airfield, it is easier and faster to have the information about the dammage in case of, so USAF accept to go further these limitations.

All of that 14 years after first preserial flight ! ie the flight quality of the bird will never be improved. Too late. The flight domain is the first thing opend in a plane developpment shedule. F35 will remain a fat and lazy jet.
And when the stealth will vanished (thanks to late radar improvements, made by russia, china, even iran) what will remain? a fat and lazy jet.

These issues do not have much impact in real life. The DAS, F-35s integrated sensors and missiles do the maneuvering for the pilot. Second, the use of afterburner and higher speeds increase detectability of aircraft. So its rarely used. Hence, notice why US stealth cruise missiles are always subsonic.

They put a speed limit on the new F-35 because it can lose its tail


Published May 4, 2020 | By admin SOURCE: EASTERN HERALD The risk that the tail of the all-new Lockheed Martin F-35 Lightning II multipurpose fighter might collapse at supersonic speeds, has forced military authorities to modify the flight regulations for that ship. There will be no structural improvements to its fuselage or other actions to fix the already discovered technical problem, they said at the Pentagon in a message sent last Friday to the Defense News website. Simply put, pilots will be advised to only overcome the Mach barrier for very short periods. The matter was filed last December “under the category ‘no plans to correct’ (the flaw)”, due to the high costs that the full repair would have entailed, according to the official response. A review of the aircraft’s length and some materials would be essential, as well as subsequent flight tests. In the middle of the year 2019, the medium already denounced the problems of the fuselage and the stealth coating and realized that the solution conceived by the military was to set a limit of less than a minute for accelerations to Mach 1.3. Since then, it has only become obvious that the Pentagon is unwilling to undertake anything to make the plane justify it’s ‘Lightning’ name again, which means ‘lightning’. Officials say the supersonic flight is not that important to a fifth-generation fighter, an optimism some experts don’t share. “Authentic condemnation” Defense News picks up the comment from a retired naval aviator, who last year said those limitations could be deadly in direct combat scenarios. The operational idea for the F-35 is to destroy the enemy aircraft before it can detect it and engage in combat, but it is not feasible to always rely on that option. The veteran cited the experience of the Vietnam War when military aviation relied heavily on missiles and put aside his “front weapon,” something that caused additional deaths in air-to-air battles. An analyst from the Russian media Svobódnaya Pressa (‘Free Press’) described what happened on Tuesday as a “real condemnation for the F-35, as a fifth-generation fighter.” Distinguished Russian military pilot Vladimir Popov explained, in statements to RIA Novosti, that the ability to maintain stable flight at supersonic speed is one of the most important characteristics for this class of aircraft. In his opinion, the defect is exposed at the end of the combat: “If all the ammunition is depleted in the attack, the value of the aeroplane as a combat unit tends to zero,” he said. “In this case, the pilot’s primary task is to break free of the chase and land safely on his airfield. If he has a supersonic regime, it is much easier to do so.”

Only on B and C models. But pilots are not worried since most flights are done in subsonic region.

never forget that F35 was studied to replace A10 and F16 in CAS, so no real need to be supersonic.

You can't make a Mustang from a draft horse.

They were meant to be multi-role fighters with more focus on attack. USN F-35C are designed for matitime strike and CAP while USMC's (RNs and RAF's) F-35Bs is designed for ground attack, and if needed air supremacy over legacy fightets.

In case F-35s are used for air supremacy, most likely to be undertaken by F-35A, it is designed to be a sniper with secondary ability to be a UFC fighter. The F-35s will not rely on speed or internal cannon to kill enemy fighters (most Vietnam, Gulf War and successive wars air kills were missile kills). Instead, it will rely on unmatched situation awareness and automated target acquisition, classification and prioritization to kill air targets. And the US is already improving the sniper bullet of F-35 with AIM-260 and upcoming extreme longe range A2A missile program.

As an important note, since F-35 in A2A mode relies heavily on stealth plus situational awareness, supersonic speed is the least of its needs since supersonic speed makes a fighter look bigger and easier to spot on radar. Hence, most stealthy cruise missiles are subsonic in order to maintain their stealthy profile.
