That account, however, is strongly disputed by USAF sources flying the F-22. "It sounds as though we have very different recollections as to the outcomes of the BFM engagements that were fought," one Raptor pilot says.
USAF sources say that the Typhoon has good energy and a pretty good first turn, but that they were able to outmanoeuvre the Germans due to the Raptor's thrust vectoring. Additionally, the Typhoon was not able to match the high angle of attack capability of the F-22. "We ended up with numerous gunshots," another USAF pilot says.
Regardless of their differing accounts, the USAF was grateful for the chance to train with the Luftwaffe. "We optimise the opportunities we get to participate in dissimilar air combat training, as those opportunities are all too rare," says Lt Col Paul Moga, commander of the 525th Fighter Squadron. "Our recent BFM hops with the German air force Typhoons were outstanding. While certain uncontrollable factors such as weather and manoeuvring limitations did not allow for full-up engagements, it is suffice to say that there was much learning across the board. The details of each set-up are privy only to the pilots that flew them, as that is the sacred standard among fighter pilots. One thing is for certain - Raptors and Typhoons are a lethal combination."
Grune says that the Raptor's advantage lies in its stealth and ability to dominate air-to-air fights from beyond visual range. That is not disputed by USAF sources.
"Its unique capabilities are overwhelming from our first impressions in terms of modern air combat," Pfeiffer says. "But once you get to the merge, which is only a very small spectrum of air combat, in that area the Typhoon doesn't have to fear the F-22 in all aspects."
The Typhoons were stripped of their external fuel tanks and slicked off as much as possible before the encounter with the Raptors, says Grune, who adds that in that configuration, the Typhoon is an "animal".
Pfeiffer notes that the Eurofighter has better acceleration and can out-climb the F-22. Additionally, he says that the Raptor sinks when it is using its thrust vectoring capabilities, although one USAF source says he is skeptical of the German claims.
Overall, Grune says the two aircraft are closely matched in the visual range arena, but Pfeiffer says the Typhoon is the superior dogfighter.

Lawmakers Seek Answers on F-22 Issues
Sen. Mark Warner (D-Va.) and Rep. Adam Kinzinger (R-Ill.) sent a letter (1) to Air Force Secretary Michael Donley on July 10 expressing their appreciation for the service's efforts thus far to ensure the health and safety of F-22 pilots, but also voicing their continued concerns over recent hypoxia-related incidents with Raptor pilots.
Specially, they cite a "hypoxia-related in-flight emergency declared by an F-22 pilot" at JB Pearl Harbor-Hickam, Hawaii, on July 6; a "restricted airflow" incident at JB Langley-Eustis, Va., in late June; and a mishap (2) at Tyndall AFB, Fla., on May 31 in which an F-22 "reportedly impacted the runway without extending its landing gear."
Warner and Kinzinger ask for a briefing within 30 days to get updated information on the aircraft's onboard oxygen-generation system and whether it provides enough oxygen to pilots at higher altitudes while they are sustaining powerful G-forces.
They also seek information on the pilot's survival gear, including the upper pressure vest, which has come under scrutiny again of late as potentially restricting the pilot's airflow and possibly contributing (3) to the cases of pilots' disorientation and dizziness.

The Air Force believes it finally understands the cause of hypoxia-like issues affecting some F-22 pilots in the last several years, and is taking a "phased approach" to retrofitting hardware and getting flight restrictions lifted on the stealth jets, said outgoing Chief of Staff Gen. Norton Schwartz on July 24.
At a Pentagon press conference to discuss his tenure as his Aug. 10 retirement looms, Schwartz said Air Force officials briefed Defense Secretary Leon Panetta on July 20 on the new findings.
Panetta, in turn, lifted some F-22 flight restrictions—enough to clear a squadron-sized group of F-22s to deploy from the United States to Kadena AB, Japan, "in the next few days," said Schwartz.
The Air Force has data ruling out any "contamination" of Raptor pilot oxygen and has fixed on faulty valve connections in the upper part of the Combat Edge full-body G-suit and a charcoal filter as the culprits in the hypoxia-like episodes, said Schwartz.
Centrifuge and altitude-chamber tests have confirmed these findings, he added, explaining the problem as "the quantity, not the quality" of the air pilots are receiving.
The filters have already been removed and the G-suit modifications will start entering service in September, said Schwartz.
For the Japan deployment, Schwartz said the jets would follow the "northern island chain" route so they are never more than 90 minutes from a usable runway, and tankers accompanying them will carry enough fuel so that the F-22s could descend and fly at lower, less fuel-efficient altitudes, if necessary.
Schwartz said the Air Force still has to go back to Panetta with a final report to get his "head nod" to resume unrestricted F-22 flying.

After years of looking into the F-22’s pilot disorientation problems—alleged to be just “oxygen” problems—the Air Force has announced that it has everything under control.
According to some defense experts, however, the Air Force still has a long way to go in proving its investigation is complete, reliable and transparent.

Royal Australian Air Force Flt. Lt. Mark Biele is an F-22 instructor pilot on exchange with the 90th Fighter Squadron at JB Elmendorf-Richardson, Alaska.
He's only the second Australian exchange pilot to fly the F-22, according to a base release.
"The exchange is important to emphasize the level of trust and commitment between our two countries," said Maj. Christopher Lazidis, 90th FS weapons director.
"It demonstrates how deep the partnership between the US and Australia is—not just that we have an Australian F-22 pilot, but an Australian that will train, deploy, and fight fully integrated within our squadron," he added.
Biele converted from the F/A-18 Hornet to the F-22 at Tyndall AFB, Fla., before joining the 90th FS.
Biele will likely aid the RAAF in standing up Australia's F-35 program after his three-year exchange stint wraps up in two years' time, states the Aug. 9 release.

La seduta è tolta, per la Signora Haney...The court case of the widow of US Air Force Captain Jeff Haney versus the contractors who built the F-22 Raptor and its life-support systems has been settled. Haney was killed in a tragic 16 November, 2010, crash in Alaska.
"The Haney Litigation has been resolved. The terms of the settlement are confidential. We have no further comment," says Lockheed Martin, the prime contractor which built the stealthy, supersonically cruising air superiority fighter.
Boeing, the major subcontractor which integrated the jet's life-support system mirrors the Lockheed statement. "The matter has settled, the settlement terms are confidential, and the company has no further comment," the company says.
Pratt & Whitney, which manufactured the Raptor's F119 engines and associated bleed-air system, did not have prepared statement, but a spokesman echoed statements from Boeing and Lockheed.
Honeywell, which manufactured the aircraft's on-board oxygen generation system (OBOGS) and environmental control systems (ECS) could not be reached for comment by press time.
Anna Haney, wife of the deceased pilot, filed the original complaint on 5 March 2012 in a court in Cook County, Illinois. The lawsuit sought compensation, which would have been chosen by the court, for Haney and her two daughters Ava and Stella Rose under the Wrongful Death Act.
The lawsuit had alleged that the contractors designed and built the F-22 Raptor with defective life-support systems including the OBOGS, ECS and bleed air system. The suit also alleged that system was built without adequate backup safety measures or proper sensors to warn the pilot if there is a problem.

No F-22 pilot has experienced an unexplained physiological incident in flight since March 8, a span covering some 10,000 sorties and more than 13,000 cockpit hours, said Maj. Gen. Charles Lyon, Air Combat Command's director of operations, in testimony on Capitol Hill on Sept. 13.
http://www.af.mil/information/bios/bio.asp?bioID=8309
"This is the longest period" without one such incident "in years," he told members of the House Armed Services Committee's tactical air and land forces panel during a hearing on F-22 pilot oxygen-deprivation issues.
Lyon said the Air Force continues to transition the F-22 fleet back to normal flight operations.
"The path to resuming normal flight operations hinges on the successful development, testing and fielding of the modified combat edge upper pressure garment valve," he said.
Fielding of the valve is expected by year's end, he noted.

Activity also continues to incorporate an automatic backup oxygen system in the jet; the first F-22 is slated to get this upgrade in January, he said.

"We are certain the F-22 cockpit and surrounding workspace is a safe, effective place to operate," said Lyon.
He added, "Continuous process improvements will ensure the safety of the F-22 workforce now and in the future."
