F 22 wll also loose.

These planes are designed on different philosophy. F 35 or F 22 are not designed to win close combats and dog fights. They are designed to shoot enemy before enemy can see them. They are designed to sneak into enemy territory to accomplish the mission.
F 22 has extensive capability to take on any opponent in WVR. But it is even more expensive than F-35. Only true challenger to an F-22 in WVR would by the PAKFA (like 15 years extra evolutionary advantage or on flip side 15 years late into the fight).

Only way F-35 can score over Su-35s is when the WVR fight is a many-on-many furball. That way F-35s using their superior computing can have a good hope against Su-35s which will eventually have to use their TVC (which in turn will sap their energy state). In smaller dogfights, I expect, F-35 against Su-35 to be the same as Typhoons vs. Su-30MKI. The Russian concept will win.

BVR is an entirely different ball game.

No way, sure the AESA might be more powerful but DAS alone works at ranges of over 1200km. Sensor fusion too is far more advanced.
DAS does not work for 1200 km .DAS on its own has a range of about 100 km on stand alone for fighter.DAS 1200 is for large ballistic missile when fused with satellite intel.

Software failures, cyber vulnerability still plague F-35

Key Points
  • F-35 software and cyber-security weaknesses remain unresolved
  • The mission system software supporting the aircraft's radar is not stable enough for combat, a key concern as the USAF prepares its jets for deployment
Software and cyber-security weaknesses in the Lockheed Martin F-35 Lightning II Joint Strike Fighter are among the unresolved deficiencies that still plague the program, even as the United States is poised to increase production, the Pentagon's top weapons tester told US lawmakers during a 23 March hearing on Capitol Hill.

"The limited and incomplete F-35 cyber-security testing accomplished to date has … revealed deficiencies that cannot be ignored," Michael Gilmore, the director of combat testing, said in a prepared statement for a hearing by the House Armed Services subcommittee on tactical air and land forces. Gilmore's testimony summarizes earlier reports that detail the risks of concurrent development and production of weapon systems.

Furthermore, the mission systems software supporting the aircraft's Northrop Grumman AN/APG-81 AESA radar is not stable enough for combat, according to Gilmore's testimony. The radar has to be restarted once every four hours of flying time, the statement said. The US Air Force (USAF) has said that fixing this issue remains its main concern before it can allow its jets to deploy in combat.

Pentagon F-35 programme manager USAF Lieutenant General Christopher Bogdan, who also testified before the subcommittee, acknowledged that problems with mission system software remain a serious difficulty. "Our most significant technical concern is the development and integration of mission systems software," he said. Each aircraft is supported by some 8 million lines of code, he added.

Sean Stackley, assistant secretary of the US Navy (USN), concurred with Gilmore and Lt Gen Bogdan in his written testimony, stating that software stability during flight test was a problem. In addition, cracking in the wings of the navy's F-35C carrier variant after too few flight hours remains a problem, according to Stackley.

More farticles of the F-35, some more riciculous than others. The F-35 is a 5th gen multirole fighter, which offers cutting edge solutions and takes aerial warfare to the next gen. With its powerful sensors and advanced weapons including the likes of Aim-120D, Meteor, I-Derby-Er, it can challenge any fighter including the Su-35s and Raptors. It's not a air superiority fighter, it doesn't need to be. It will have more advantages than other aircraft including the Raptor till atleast 2030 going into battles. From next gen helmets, good AESA, sensors like DAS, EOTS, it allows any skilled pilot to be a good tactician as the pilot is more focused on fighting with the aircraft.

The likes of PAKFA are still some time away from full scale production and their sensors aren't as advanced.
What are you talking about? The F35 has a cannon for which software has not even been written yet.
What you are saying is that it is only as good as the missiles it is carrying, and after that, a flying dud? What about dogfight? It is well documented that the F35 lacks the kind of energy needed to perform supremely in a dogfight, especially against the Su35 and Su30s.
What kind of fighter is a fighter without a gun? Do you expect the pilots to swordfight?

You can correct that to a PSLV sized rocket. It was said to be the tail end of a Falcon 9 rocket facing the DAS sensors. Falcon-9 is like 500 ton launch mass while OTOH, even the R-36 Satans are around 200 tons. Realistic ICBMs touch ~50 tons.

I don't know what the JSF program office was thinking when it decided to crow about that brownie point :crazy:.

DAS can pick out variety of targets, indeed rocket launches at over 1200km away, you can be sure DAS can easily pick out large fighter targets ike the Su-35 at over 250 km away, transports, awacs etc can easily be picked out at over 400km away.

You are making big deal out a test flight in a simulated dogfight where it's envelope was found to be needing further tweaking, the same is being refined. The aircraft will be a capable all rounder post FOC which planned for 2020 when its software and hardware is certified. As for energy, as per report from RNLAF test pilots, the F-35 is significantly more capable than the F-16 it primarily replaces. More so in a dogfight with sensors like EOTS, DAS and AESA, excellent 360degree situational awareness, the revolutionay helmet, the pilot can almost entirely devote his concentration on the fight which is formidable thing.

The latest tech only allow at 100 km in practical from back ,that is the theoretical limit and is yet to be achieved as it requires a lot of quantum technology .

Not really, even the MKI with OLS can pick out targets at over 90 km away in rear and around 40 km in front. F-35 with DAS should easily be able to detect Flanker like targets at over 200km in rear and over 100 in front. Many of the problems that plague the F-35 are indeed related to this quantum tech that is being refined.

Not a biggie and already old news by a month, the radar fix is being deployed end of March. This should solve the problem of needing to restart the radar mid flight.

Give the source for 200 km,the quantum tech is in its infancy,need about 20 year to mature enough.

F-35C AC trials:

and the latest GAO (U.S. Government Accountability Office) report:
http://www.thefiscaltimes.com/2016/04/15/F-35-s-Billion-Dollar-Brain-Fails-IQ-Test
The latest problem with the F-35 Joint Strike Fighter? There might be something seriously wrong with the gold-plated aircraft’s brain.
A Government Accountability Office report released Thursday raises concerns about the jet's $16.7 billion Autonomic Logistics Information System (ALIS). The software is essentially the brain that enables the fifth-generation warplane to operate, tracking everything from the amount of time the aircraft spends in the air to when the engine needs a tune-up.

The roughly $400 billion F-35 effort has had more than its share of software hiccups already, highlighted by recent findings that the aircraft’s billions of lines of computer code might be vulnerable to hacking.

If the bugs persist, it could have a cascading effect on the rest of the Defense Department’s timeline for the warplane, which is already years behind schedule. Serious problems with the logistics system could delay important program milestones, including the U.S. Air Force declaring its version of the jet ready for deployment later this year.

In its report, GAO identified two major problems with Lockheed Martin’s ALIS, the first being that the system itself may not be deployable.

The ALIS tool gets plugged into a jet, sending data to two 1,600-pound sever racks. Each F-35 squadron requires its own set of ALIS computers, making it difficult to operate since it “requires server connectivity and the necessary infrastructure to provide power to the system,” according to the new report.

Last year the Marine Corps, which often deploys to remote locations, declared its version of the F-35 ready for deployment “without conducting deployability tests of ALIS.”

A slimmer version of ALIS that can fit into moveable cases -- capable of being carried by two men and weigh approximately 200 pounds each -- was put into operation last summer. However the Pentagon “has not yet completed comprehensive deployability tests,” the GAO report states.

he second key issue is that there’s no alternative to ALIS if there’s a problem. That lack of redundancy is compounded by the fact that all ALIS data is fed into a “central point of entry” and then to an operating unit in Fort Worth, Texas.

“If either of these fail, it could take the entire F-35 fleet offline,” GAO warns.

The report also raised concerns about the system’s inability to communicate with the systems aboard older aircraft, and noted that ALIS users are worried about transferring data between classified and unclassified computer servers.

The watchdog office suggested the Pentagon develop a “holistic” plan to address myriad issues with ALIS to make sure biggest problems with it are taken care of before the F-35 enters full production in the early 2020s.
