Here's an insider's explanation of why the Air Force's hot new F-22 fighter jet is exactly the wrong aircraft for shooting at Qaddafi's forces on the ground in Libya.
By Col. David
Gurney (USMC, ret.)
Best Defense office of strafing and
bombing
There aren't many things more fun than strafing targets on the ground, and for tactical jet pilots, there are few activities more dangerous (or in the case of a F-22 Raptor, more stupid). The 20mm six-barreled Gatling gun on the F-22 is mounted for an air-to-air knife fight (inside a half mile). The M61A2 features high rates of fire and a tremendous muzzle velocity, but there are only 480 rounds of ammunition, just over four one-second bursts). This ammunition was not designed for ground targets, it was specially designed to blow up other aircraft. The Raptor also lacks the armor and the price tag required for fecklessly dueling Grunts who own automatic weapons and hate pilots who make more money and look better than they do.
What most non-tactical jet pilots don't know is that air-to-air and air-to-ground cannon are mounted differently. An aircraft with an air-to-mud cannon is at a gunsight depression disadvantage in a dogfight, and the opposite is true for fighter pilots who wish they were heroic attack pilots. Consider for a moment. If your primary mission is to make earthmen miserable, the axis of your cannon will be depressed from the longitudinal axis (fuselage) of your aircraft. This allows pilots to enjoy a more shallow dive and therefore leisurely opportunities to perforate the rabble and break their toys. Fighter pilots, conversely, have cannon that are biased above the longitudinal axis, because most of our enemies don't like to get shot and are pulling as many G's as they can to keep from getting their jump wings. If your gun is pointing up a few degrees, you don't have to pull your nose all the way to the bogey's jet before your glowing "death dot" is resting on the back of his helmet. This also means that F-16 and F-22 pilots have to strafe in a steeper dive and shoot quicker to keep from suffering cement poisoning.
Even if there aren't any inconvenient Grunts with automatic weapons and shoulder-fired missiles in the target area, strafing is flat dangerous. In a shallow dive at 550 knots, Harrier pilots need to take a 5-G divergent "jink" (left or right) from the delivery azimuth after a one-second burst to prevent a fateful rendezvous with their own depleted uranium ricochets. And it's worse when your targets are exploding (not least because it is tempting to admire one's work). Certainly strafing is viable with a purpose-built system like the A-10, which was optimized for this kind of fun (and couldn't catch-up with its own bullets on its best day). The application of an F-22 20mm cannon against ground targets isn't going to do much beyond getting some Raptor pilot 20 percent closer to enemy ace status.

Best guest commentary ever.
is a "Former" Harrier pilot, not an "Ex-". ...Jeesh.
Loved calling in our Crusaders back in the '50s. Didn't know then, as a Devildog corporal, that ground attack was 10 times as hairy as air to air. It takes a large pair to get down on the deck. It's not one on one down there; everyone is shooting at you or throwing rocks, etc.
"Fighter pilots who wish they were heroic attack pilots."
I sense a moment or two's smirk at the keyboard as this sentence was tapped out.
...sorting out the good guys from the bad guys. You could use an F-22 to drop JDAMs, (GPS guided bombs), but I've been told that is as much fun as being a UPS driver, but without the spiffy uniform. You can do that with almost any of our planes, but that is kind of what the Joint Strike Fighter was designed for.
The easy part of the no-fly zone is not letting anything fly. Shooting down planes and controling air space is fairly straightforward. Knocking out ground based air defenses is more difficult, since radars and launchers are mobile and not always in the same place.
Straffing implies that we are using guns (not bombs) to shoot targets on the ground. That is a lot of fun for the guys in planes and guys on the ground directing those planes (says former ground dude). A-10s are great at straffing and F-22s are not, for all the reasons the Colonel pointed out.
If we are using A-10s to straff, it implies that we are either taking out air defense (probably not) or armored vehicles. The rebels don't have armor, so figuring out the good guys from the bad guys is fairly simple in that case.
Without people on the ground to tell the guys in the air who the good guys and bad guys are, the best we can do is take away Qadaffi's air force, some tanks, and some armored vehicles. This turns the war into a fight between guys with pickups and AKs. Unfortunately, trucks full of food for orphans going into cities and trucks full of ammo look quite similar from 10,000 feet.
In other words, without exercising Tom's Jawbreaker Option (SOF guys on the ground, telling planes which Toyoda Hilux to blow up), the fight will still be decided on the ground. And even if we had F-22s, Joint Strike Fighters, and every UAV in the US military enforcing the NFZ, the rebels can still lose.
A perfect air campaign is like a perfect communications plan or perfect intelligence report or perfect logisitics: you can have it and still lose.
Good bet: if it's on the Coastal highway East of Sirte, going West, it's rebel.
If it's on the Coastal highway West of Sirte, going East, it's Regime.
Increasingly, it sounds like, we'll be seeing Toyota v. Toyota 'armored' combat, not least because gas mileage becomes a very big issue along that long coastal road.
Nb. the distance between Tripoli and Benghazi is roughly the same as the distance between Sacramento and Salt Lake City. The logistics are worse.
I would say that, with near 100% certainty, we have men on the ground inside Libya, and indeed have had them there for a considerable time longer than the air-war ever existed. From what I have read in other articles, U.S. SF have been on the ground in eastern Libya, organizing and training rebels for quite some time. I can only assume that other SOF and British SF in particular are currently scowering the countryside cataloging targets, and gathering intel.

IRONCAPT your comments make sense. However, I understand that the rebels do have some tanks which were active very early but they were unable to successfully maintain, ammunition and fuel them.
A recent transmission from a Benghazi radio station.
That said, I imagine the biggest issue is fuel -- the T55 gets about 300 miles on its 250 gallon tank. This is about half-way (one way) from Benghazi to Tripoli. The rebels are smart to keep their captured armor as mobile pillboxes, especially because of difficulty ensuring no mishaps to tailing tankers..
(These two cities are about as far from each other as Sacramento and Salt Lake City).
So the warfare comes to look like a Toyota-branded "Road Warrior."
That B-17 in the title photo is a 91st BG aircraft named "Wee Willie". "Willie" flew128 missions but her luck ran ou on April 8, 1945, when, depending on the source, she was shot to pieces by ME-262 or by flak.
Now for the good colonel's comments.
There was a LOT of WWII strafing done by aircraft with guns mounted on the longitudinal axis.
The first Vulcan pod mounted on F4-C's and F4-D's in Viet Nam were pressed into service in an air to air role because those aircraft had no internal cannon. But they also fired down the longitudinal axis. And they were -intended- for ground attack.
And the venerable A-10, also specifically designed for ground attack - that aircraft has a very large cannon that - fires down the longitudinal axis.
Yeah, there are a lot of reason not to use F-22's to strafe ground targets but the fact that the guns fire down the longitudinal axis is surely the least of them.

....that I didn't like.
Indeed at a state ball not too many years ago I met a whole passel of them - and their wives. The airedale ladies were so taken by our Stetsons and Spurs I thought things were going to get down right freaky.
But in my earnest honesty to Mrs Hunter and my need to not follow in the infamous footsteps (pre-emptively as it was) of COL James Johnson III I and my staff retired quietly into the night instead. - wink -
But seriously, we groundpounders do love to have CAS on standby.
Grunts who ..... hate pilots who ..... look better than they do
Hunter, that could also be the reason that you left early. {;*))
In WWII, both the A-26 and the B-25 carried down-angled M-2, .50 cal. machine guns in the nose and, later, in the wings as well. One model of the A-26 had 14 forward-facing guns for strafing. The B-25 had as many as 10 forward and 4 aft-facing. These configurations were most popular in the Pacific where low-level ground attack was more effective than high-level bombing. I once slept under the wing of a tan A-26 in a hangar at Hulrburt Field.
Although they would prefer ground confirmation, the AC-130 at 10,000 feet can "see" with ever-improving sensors and can hit point and area targets with precision at night (when they fly.) In a place like Surt, a patient AC-130 crew should be able to pick out armor and artillery for targeting without assistance from the ground. By the same token, the SBS worked in Tora Bora and both the SAS and COS should be able to identify and lase targets from the ground. We do not need Delta and SF to do this. In fact, there is a YouTube video of an AC-130 crew saving an SAS unit on a snatch mission in Afghanistan - excellent communication in a chaotic situation. We do need to avoid American boots on the ground in yet another Arab country.
The rebels withdraw nicely in two orderly lanes and they turn around well. They just have no clue how to aim, much less fight. One can only hope that their tribal opposition is just as bad. It is when they encounter the 32nd Brigade that they will be in real trouble without vigorous CAS.
...but you left out the really important part:
...Grunts who own automatic weapons and hate pilots WHO MAKE MORE MONEY and look better than they do...
On looks I think we definitely had them, money...well, I can't compete there.
Again, more on topic, I want to stress how much we like those attack jockeys - esp. Warthog drivers. The fighter crowd...notsomuch. (I will say this no fly zone probably gave the fighter guys their first mission in what 40-50 years? How long did that last 5 minutes?)
There have been at least 2 incidents of USN fighter aircraft shoot downs of Libyan aircraft since August 1981, so call it 30 years ago. Not a whole lot of work for the fighter community during the Gulf War, but just the threat of them caused the Iraqi Air Force to haul trash to Iran or bury themselves in Iraqi sand. Mission successful either way.
In the 80s in Europe they would run practice missions on us working on bridge missions. They flew up the rivers at tree top level it seemed. Everytime one went over my only thought was, "Thank God they're on our side." Replacing them with highflyers always seemed kinda nuts to me
My old bunk at Ft. Lewis, WA used to overlook the airfield. In fact, I think stationary hovering of a Chinook right outside my window for about an hour at a time was a popular training exercise.
That was annoying, but one of the most terrifying sounds I have ever heard remains the A-10 doing dry runs in my general direction. Sincerely would not want to be on the receiving end of that nastiness.
Dear Mr Ricks,
This is a very nice guest post indeed. However, it makes no sense with regards to F-22 in Libya.
No-one in their sane mind would suggest attacking ground targets with a gun. The only aircraft that are designed to do that in a hostile environment are A-10s. (And they do indeed, as shown yesterday in Misrata port.) Everything else, from F-15s to Rafales will (and did) attack ground targets from a safe altitude with guided bombs and missiles. No-one will unnecessarily risk taking a random bullet from an AK-47. Or to take the argument to the extreme - the B-2 has no gun whatsoever, and yet it was used exclusively for air-to-ground.
The reasons why F-22s didn't participate are the following:
1) Libyan air defences were pretty ancient and could be taken out with old-school stuff, like TLAM. (Raptor a2g is planned against state-of-the art Russian & Chinese radars and air defences, like S-400.)
2) F-22 have a very limited overall a2g capability. (Basically, just JDAMs and SDBs.)
3) Flying F-22 in full combat stealth could reveal their characteristics to other forces operating in the region. (When F-22 flies for air shows, it always carries a device that magnifies its radar cross section to keep real specs secret.)
4) The cost of relocating F-22s to Europe. Other USAF planes were based in Europe, had all their ground support there. (And B-2s flew round mission from US.) You would have to move a lot of stuff to Italy to make it work.
But guns is not one of the reasons... ;)
the reason I read this blog is that I learn stuff
and this post lives up to the benchmark.
question: I read somewhere that the A10 was no longer being produced, largely because it was out of favor in the air force, without massive congressional $ to dole out, too devoted to stupid un-sexy, un Air Force jobs like supporting infantry, etc.
Is this true?
If it is true, wtf?
Here's a better question: Why did the USMC never express interest in the A-10. I don't know if it can fly off a boat, but could there be a better machine made for the needs of light infantry? Surely, it's a closer fit than F/A-18s.
I had the chance to ask then CMC Gen Krulack that very question; specifically, why didn't at least the 4th Marine Air Wing (USMCR) have 3-4 squadrons of A-10s as it was easier to fly and maintain than the Harrier and therefore, the Reserve A-10 guys would be able to spend more time traning in the air-to-ground role with the rifleman. I was in turn passed to a card carrying Harrier driver who assured me 17 ways from Sunday, and very politelty of course, that they didn't need no Air Force designed/produced piece of junk. Wonder what the response would have been from an rifle-carrying infantry battalion commander? Bottom line from my perspective is the Harrier mafia had (or perhaps has) too much control/influence in the Marine Aviation world; just my opinion
The A-10 would be a great things for Marines. I can't think of a better platform for CAS but I'd put Marines in the cockpit. Marines seem to have a better unederstanding and kinship with Grunts.
The Harrier Mafia will be the death of the tactical fixed wing aviation if they don't wise up.
S/F
WTF, it's true. The Air Farce wanted no part of the A-10. It ran counter to the image of the supersonic fighter-jock dueling with the enemy in the clear blue skies. So the AF tried to (and did) kill A-10 production and hand off the remaining inventory to the Reserves. BTW, this AF attitude toward close air support is a major reason why the Army developed its own fleet of attack helicopters, and the Marine Corps has its own air wings.
According to Wikipedia, there are A-10 units in the Active AF, Guard, and Reserve. The AF Reserve is well-integrated into Active Air Force operations. Therefore, the A-10s or the A-10 pilots over Libya could be from any of these 3 sources. The same for Afghanistan.
Of course the good Colonel failed to mention to attrition rate in the Gulf War was among the highest. I believe they lost 1.5 Harriers for every 1000 sorties. 5 were lost. Every Harrier hit by a SAM was shot down. They are kind of like heat seeking missile sponges.
Good chalk talk on the differences between air to air and air to ground gun systems. But I know a couple of Hornet pilots who popped the tops off T-72s during the Gulf War, strafing from F/A-18 which has longer legs and more payload. But I guess I am talking like a heretic.
S/F Mac!
I responded to the Colonel's post by criticizing the F-22 and F-35 as replacements to Harriers and most importantly, the A-10. Let me try it this way. Twenty years from now what airplanes will own the ground support/tank killing mission for the US armed forces? How will they compare to the present planes tasked with these missions in terms of firepower, cost, and most importantly expertise. Will their commanders be willing to committ them to missions that expose them to the perils noted above? Any thoughts?

Can't say within 20 years, but beyond that, I believe you will have UAVs providing air support.
My prediction will be the JSF will be the last manned fighter bought.
We had some debates in our university about whether the US and Nato should focus more on airstrikes or sanctions in order to smoke Gaddafi out. This article explains quite well why the Air Force still has to make some improvements in order to be more efficient with their strikes. I also read in recent military parfum article that the French already had lost some airplanes in the war on Gaddafi. So far it seems like as if the war itself is not ending yet.
