No communications? What about the PRC-90's in their survival vests?
Lockheed's F-22 Raptor Gets Zapped by International Date Line

Six Lockheed F-22 Raptors have Y2K-esque glitch of their own over the
Lockheed's F-22 Raptor is the most advanced fighter in the world with its
stealth capabilities, advanced radar, state of the art weapons systems and
ultra-efficient turbofans which allow the F-22 to "supercruise" at supersonic
speeds without an afterburner.
The Raptor has gone up against the best that the US Air Force and
Navy has to offer taking out F-15s, F-16s and F/A-18 Super Hornets
during simulated war games in Alaska. The Raptor-led "Blue Air" team
was able to rack up an impressive 241-to-2 kill ratio during the exercise
against the "Red Air" threat -- the two kills on the blue team were from
the 30-year old F-15 teammates and not the new Raptors.
But while the simulated war games were a somewhat easy feat for the Raptor,
something more mundane was able to cripple six aircraft on a 12 to 15 hours
flight from Hawaii to Kadena Air Base in Okinawa, Japan. The U.S. Air
Force's mighty Raptor was felled by the International Date Line (IDL).
When the group of Raptors crossed over the IDL, multiple computer systems
crashed on the planes. Everything from fuel subsystems, to navigation and
partial communications were completely taken offline. Numerous attempts were
made to "reboot" the systems to no avail.
Luckily for the Raptors, there were no weather issues that day so visibility
was not a problem. Also, the Raptors had their refueling tankers as guide
dogs to "carry" them back to safety. "They needed help. Had they gotten
separated from their tankers or had the weather been bad, they had no
They had no communications or navigation," said Retired Air Force Major
General Don Shepperd. "They would have turned around and probably
could have found the Hawaiian Islands. But if the weather had been
bad on approach, there could have been real trouble."
"The tankers brought them back to Hawaii. This could have been real serious.
It certainly could have been real serious if the weather had been bad,"
Shepperd continued. "It turned out OK. It was fixed in 48 hours. It was a
computer glitch in the millions of lines of code, somebody made an error in
a couple lines of the code and everything goes."
Luckily for the pilots behind the controls of the Raptors, they were not
involved in a combat situation. Had they been, it could have been a
disastrous folly by the U.S. Air Force to have to admit that their aircraft
which cost $125+ million USD apiece were knocked out of the sky due to a few
lines of computer code.
"And luckily this time we found out about it before combat. We got it fixed
with tiger teams in about 48 hours and the airplanes were flying again,
completed their deployment. But this could have been real serious in
combat," said Shepperd.
We always lead the fighters across the pond. They don't have the comms to do cross-oceaniac flights.
The article says no comms.
The pilots have their PRC-90's, turn them on, come up on guard and talk to the tankers.
Did someone not get the memo on the TPS reports?
I wonder how long it was before the tanker knew they were out of comms. We don't routinely chat with the fighters until they're ready for a top off.
Unless the mode C went off the air the tanker was probably oblivious.
Whoops. Gotta be a weird feeling being a thousand miles out over the open ocean in a 125 million dollar plane staring at a bunch of C:/ prompts.
Your wrong, the article I posted has NOT been posted prior to my posting it.
You link to a post I posted and a post by Chairborne, neither of those posts reference the article I posted.
If you're going to call 'dupe" then do your research first.
Where did I call dupe and the bug story has been posted before... it has.
Before you get your panties in a wad comprehend what you read.
I did not realize this was a contest and posting additional information was some sort of foul. Where is the penalty box?
Where has the article that I posted been posted before here on ARFcom?
Provide a link.
The article I posted gives more detail than any of the two posts you reference.
Date line caused GPS glitch on Raptors

Someone forgot to turn the F-22A Raptor’s clock forward, so to speak.
It turns out that on Feb. 11, when 10 Raptors crossed the international date line on their way to Kadena Air Base, Japan, the jets’ Global Positioning System suddenly didn’t know where the jets were.
The deployment marked the first time the Raptors, which cost about $330 million each including development charges, crossed the date line in the middle of the Pacific Ocean.
“Any time you bring on a new weapons systems, there are going to be things that turn up,” said Col. Tom Bergeson, an F-22A pilot and commander of 1st Operations Group, which is responsible for the deployed Raptors. Bergeson was not with the Raptors that turned back. Instead, he was at Nellis Air Force Base, Nev., where 14 Raptors from the 1st were participating in a Red Flag exercise.
The jets over the Pacific weren’t in any immediate danger, Bergeson said. But since precision navigation is a requirement if a pilot has to find a small island strip in the Pacific, the decision was made for the fighters and their escort tanker to turn back and land at Hickam Air Force Base, Hawaii.
The F-22A’s contractor, Lockheed Martin, developed software within two days to solve the glitch. Soon after, it was test flown on an F-22A at Nellis, Bergeson said.
The jets at Hickam got the software fix , and by Feb. 18, the F-22As were on the ground at Kadena.
I never said the article that you posted been posted before, I said the bug story had been posted before.
Like I said I did not know this was a contest. Go ahead and red flag me... I must be guilty of something.
Is that just your avatar or is there a deeper meaning?
Lighten up buddy. Nuk nuk nuk!
Dang, I wonder how all of the pilots in WWII ever managed to get anything accomplished without GPS.
Don't they teach basic NAV anymore?
Even the old Dead Reckoning?
Well in fairness a lot of pilots in WWII ended up dead because of navigation errors. Dead Reckoning ain’t much help in the vastness of the Pacific. They used use radio direction when flying in to Hawaii before WWII.
I know that, it was just that that line struck me as funny.
Maybe there is too much dependance on hi-tech nowdays.
