主题：F－22在阿拉斯加演习中取得144比0胜利(转贴) (上) -- 韩亚梓

"If a Rivet Joint is trying to get triangulation [on a precise emitter location], he can get more [voice] information" from an F-22, Keys says. "If an AWACS sees a heavy group 40 mi. to the north, Raptor can come up and say it's two F-18s, two F-15s and four F-16s."

Moreover, Keys says, modifications are underway to transmit additional target parameters--such as sensitive, high-resolution infrared data--from the F-22 with a low-probability-of-intercept data link.

"Getting data into an F-22 is not hard," Keys says. "Getting it out [while staying low observable] is more difficult. We bought the links, but we just don't have them on yet."

The F-22's advanced electronic surveillance sensors also provided additional awareness of ground activity.

"I could talk to an EA-6B Prowler electronic attack crew and tell them where a surface-to-air missile site was active so they would immediately know where to point their electronic warfare sensors," Tolliver says. "That decreased their targeting time line considerably."

In addition, the F-22 can use its electronic surveillance capabilities to conduct precision bombing strikes on emitters--a capability called destruction of enemy air defenses.

"And future editions of the F-22 are predicted to have to have their own electronic attack capability so that we'll be able to suppress or nonkinetically kill a site like that," he says.

The F-22's operating altitude and additional speed during the Alaska exercise also garnered praise.

"We stayed high because it gives us an extra kinetic advantage with shooting, speed and fuel consumption," Tolliver says. "The Raptor typically flies way higher than everybody else and it handles like a dream at those altitudes." Tolliver wouldn't confirm the operating altitude, but Pentagon officials have put it at 65,000 ft., which is at least 15,000 ft. higher than the other fighters.

"There were times we went lower, maybe to visually identify a threat or if we were out of Amraams and there was a bandit sneaking in at low altitude," he says. "The Raptor would roll in and kill him with a heat-seeking missile."

The lopsided combat ratio resulted because, "they never saw us," Tolliver says. "We got there without being detected, and we killed them rapidly. We didn't do any major turning. It's not that the J-Turn maneuver isn't fun, but we didn't get a chance to use it."

The F-22's Mach 1.5 supercruise capability also got a workout in Alaska. Because only eight F-22s were ever airborne at once during the exercise, four of them were constantly involved in refueling from tankers flying orbits 150 mi. away. Supercruise got the fighters there and back quickly. On station, the fighter would conserve fuel by cruising at high altitude.

"We also used supercruise quite a bit because the fight was on such a large scale," Tolliver says. "The airspace was roughly 120 mi. by 140 mi. We could sit up at high altitude and save our gas and watch. We don't hang out at Mach 1.5. With our acceleration, when we saw the threats building, because we could see them so far out, we'd dump the nose over, light the burners and we were right up to fighting speed."

During a typical day in the Alaska "war," 24 air-to-air fighters, including up to eight F-22s, defended their aerial assets and homeland for 2.5 hr. Air Force F-15s and F-16s and Marine F/A-18s simulated up to 40 MiG-29s, Su-22s, Su-24s, Su-27s and Su-30s (which regenerated into 103 enemy sorties in a single period). They carried AA-10s A to F, Archers, AA-12 Adders and the Chinese-built PL-12. These were supported by SA-6, SA-10 and SA-20 surface to air missiles and an EA-6B for jamming. Each day, the red air became stronger and carried more capability.

As a result of all the emitters in the battlespace, the F-22's ability to map the electronic order of battle (EOB)--what's emitting and from where--proved critical.

"I love intel, but it's only as good as the last time [analysts] got a data update, which could have been hours or even a day earlier," Tolliver says. An F-22 "gets rid of the time delay. I can plot an EOB in real time. I'm not saying we're better than a Rivet Joint, but I can go places that it can't. If he's 150 mi. away, he's probably not going to be able to plot a high-fidelity threat location as quickly as I can."

The adversaries were wily and didn't want to lose.

"We had guys running in at 500 ft. off the deck," Tolliver says. "We had guys flying in at 45,000-50,000 ft. doing Mach 1.6, trying to shoot me before I know they are there. They would mass their forces and try to win with sheer numbers. None of it worked."

A tactic used by the F-22s was actually developed and practiced in smaller scale at Langley before the exercise. Raptors worked in pairs, integrated with F-15Cs or F/A-18E/Fs.

"I could help target for them from behind and above," Tolliver says. "We really don't have a name for what we were doing other than integrated ops. I was able to look down and smartly target F-15s or F/A-18s to groups at ranges where they could not yet [detect] the target."

Yet, there are a number of F-22 capabilities that are shrouded in mystery, including electronic attack, information warfare and cruise missile defense.

"It's no secret that one of our mods is to put electronic attack on board and then we will play a role in combating networks," Tolliver says. "We're already involved in the collection part. When we come back from a mission, we have the ability to download EOB data that's turned into intelligence pictures. This makes us an intelligence platform doing nontraditional ISR by bringing back emitter data so that teams can go out and conduct information operations."

The next step will be to pass the detailed information about surface-to-air missile locations, capabilities and emission details (called parametrics).

"If I have characterized, say an SA-10, I can send it verbally to AWACS and they can send it out to other platforms," says Maj. Shawn Anger, an F-22 instructor with the 43rd Fighter Sqdn. at Tyndall AFB, Fla. However, "I can't pass the parametrics characterization. Hopefully, we'll be able to shoot it up the radar"--a new capability for the radar, which is being developed to send large, high-bandwidth imagery files.
