Russian fighters for the USAF/USN? The ultimate irony
by Robert W. Kress with Rear Adm. Paul Gillcrist, U.S. Navy (Ret.) Editors note: In this wonderful piece of aeronautical and political irony, it seems that our newfound but uneasy friends, the Russians, may be our best source of new fighter aircraft. Bob Kress, ex-Grumman VP of advanced programs and chief engineer on the F-14, and Adm. Paul Gillcrist, retired USN fighter pilot, make a convincing argument that rather than spend ridiculous sums for new fighters that will probably show up too late to do us any good, we should buy Sukhoi Su-27 airframes and "Americanize" them with our engines and flight-control systems. Controversial? Absolutely! Logical? Make your own decision.
RIGHT: The Su-27 is bigger than the F-14 and F-15, and its capabilities and economics are so outstanding that a number of nations are in the process of adapting it to set it up as the primary U.S. foe in future conflicts (photo by Katsuhiko Tokunaga).
Prelude
Soon after Desert Storm, by some inexplicable miscalculation, the U.S. Navy voluntarily opted out of the important sea-based, deep-interdiction mission it had brilliantly carried out during and since WW II. It decided on the early termination of the A-6 program and to scrap the new A-6 "composite wing" program for which Boeing had already been paid hundreds of millions of dollars. This would have carried A-6Fs well into the next century.
In the strike configuration for which it originally had been designed, the F-14D was to have been the bridging mechanism between the A-6 and the Joint Strike Fighter (JSF). It is hoped (repeat, hoped) the JSF will arrive easily in the next millennium. With the A-6 out of the picture, and until the JSF arrives, the F-14D is the only game in town that has the same punch.
The problem with using the F-14D as the bridge between the two aircraft is that it is on the edge of extinction. In another inexplicable move, beginning about 1990, the U.S. Navy, per orders of then Secretary of Defense Richard Cheney, planned to phase out of the F-14 program and, apparently to ensure there would be no second thoughts, ordered the destruction of all F-14 tooling. Incredible!
The F-18 E/F program that is supposed to take over the sea-based, deep-interdiction, precision-strike mission does not have a long-range, high-payload, precision-strike capability, so the F-14Ds are the current workhorse delivery men of the 2,000-pound, LGB/radar-guided bombs in the many trouble spots around the world, as required. The USAF tries to supplement U.S. Navy strikes but is handicapped by diplomatic and political constraints.
Unfortunately, the tragedy does not stop there. The requirement for the Nimitz and follow-on class carriers hinges, most experts say, on its ability to carry out sea-based, deep-interdiction missions. Without the F-14s, Congress will not support the construction of more $3.5 billion Nimitz-class carriers if deep-strike aircraft are not ready on the first day of the conflict.
LEFT: Grumman F-14Ds, as based on the USS Constellation, are on the edge of extinction and are our last Naval aircraft capable of carrying heavy bomb loads for long distances (photo by Randy Jolly).
Somebody in the White House will have to answer the Presidents question, "Where are the carriers?" with the reply, "What carriers?" We decided not to build any; remember? The U.S. Navy
The U.S. Navy retired the venerable long-range, heavy-attack A-6 aircraft, not because they lacked their original capability and survivability, but because they were disintegrating due to old age. They went into service in 196237 years ago!
LEFT: the Grumman A-6E Intruder, now taken out of the fleet, was neither fast, nor glamorous, but it was rugged, reliable and carried an immense bomb load on long, low missions. It has no direct replacement (photos by Randy Jolly)..
The F-14D has now taken over for the A-6 in the fighter/bomber role as it was originally designed to do. On top of that, when the Tomcat has loosed its bombs, it is a formidable dogfighter! With the 150 or so F-14s left, however, the U.S. Navy can only maintain this fighter/bomber force until about 2010if it is lucky! And even doing that will require quick funding of restoration efforts to a lot of aircraft.
LEFT: according to the authors, the F/A-18 is simply too small to carry either the fuel or ordnance required by deep interdiction missions.
Cheneys order of no more F-14 production was a wasteful move that cannot be explained rationally, nor was there ever any reason offered. The effect of the order, however, was to leave a clear path for further acquisition of the F-18A and its desperately needed mission-performance upgrade, the F-18E. The F-18s are good airplanes, but neither version comes close to the payload/range capability of the F-14 or the A-6.
The cake was iced by the acquisition of Grumman by Northrop in 1993the cat devoured by the mouse, so to speak. Seventy percent of the aircraft on carrier decks at the time were Grumman-built. On the other hand, Northrop had never built a tactically significant aircraft in its entire 60-year history.
The USAF
The USAF problem is different. The Advanced Tactical Fighter (ATF) program resulted in the development of the excellent Lockheed F-22 stealth fighter and the very powerful and well-behaved Pratt & Whitney F-119 fighter engine. The USAF has many upgraded F-15 fighter/bomber aircraft in inventory and could build and upgrade even more. So, acquisition of the F-22 is not as critical an issue, timewise.
The problem lies in the enormous acquisition cost of the F-22 (see Aerospace America, November 98). The cost associated with introducing it to service would probably result in the forced retirement of many workhorse F-15s. Further, the effects of stealth aircraft design measures on fighter aircraft performance, cost and combat operability have been seriously questioned.
The F-15s must be replaced in the next 10 to 20 years, but with which aircraft?
Scale models show the relative sizes of the different fighters. From the left: MiG-29; F-14D; Su-27; F-15; F/A-18. Note the tiny relative size of the F/A-18 (photo by Walter Sidas).
The threat
On the other side of the fence, our combined U.S. Navy/USAF fighter/bomber force will face approximately 404 Russian Su-27 Flanker aircraft by 2002 ("Janes All the Worlds Aircraft"). China has been licensed to build 200 (no license to exportso they say!).
The Su-27 is already known as a premier highly maneuverable fighter. What is less known is that it is a brute of an aircraftbigger than the F-14 and F-15. It has a huge internal fuel capacity and, like the F-14, can carry a lot of very large bombs in attack rolesneatly hidden from radar detection between the podded engine nacelles. In addition, its external shape results in a naturally low radar signature without compromising its performance. The vaunted MiG-29 is a midget compared with the Su-27not unlike comparing the F-18 with the F-14. No wonder the world market opts for Su-27 payload/range versus the MiG-29. Even better for our purpose, the Su-27 has already been modified for carrier operations, and it was planned for the first Russian carrier, the Adm. Kuznetzov.
By 2002, the U.S. will be outgunned by an ever-growing number of countries owning the Su-27. The Su-27 has a deep-strike capability thats on a par with the current 500-nautical-mile U.S. capability, which, by the way, is in the process of rapidly fading to 300 n.m. as the F-14s go out of service and are replaced by F-18s with half the bomb load. The same goes for the F-15, except that its strike bomb load is on a par with the F-14, and it isnt disappearing as quickly.
We need some more affordable, high-performance "big guys" soon! So what can be done?
An American Su-27?
Before assuming that the concept of buying Su-27s for the USAF and USN is a whacky idea, lets first see whether it has some merit. The Su-27 is a known excellent fighter. It has been partially navalized. It is a big brute. In the event of a conflict, we will be nose to nose with it worldwide. It exists and is in production, so we could easily buy Su-27 aircraft models as gap-fillers; we already have acquired two for evaluation. To make things even better, the airplane is inexpensive by any standards.?
A recent unofficial quote from a Russian source says that Su-27s can be bought for about $8 million apiece. Perhaps the carrier version would cost substantially more. Compared with F-18E/F costs, the Su-27 may offer enormous procurement savings plus large mission- and combat-effectiveness benefits.
Aviation Week recently announced plans by Australia to replace its F/A-18s and F-111s with MiG-29s and Su-27s. Maybe this proposal is not such a crazy idea after all!
In the long term, we would want to upgrade Su-27 models in thrust and avionics to give us an edge over the worldwide Su-27 threat. The Pratt & Whitney F-119 engine is significantly more powerful than the Russian Su-27 powerplants and can be built with elegant pitch and yaw thrust vectoring. The General Electric F-120 F-23 engine could also be used. Without being specific, the U.S. avionics industry should be able to substantially upgrade Su-27 systems. Cost will be the driver, but here, the Su-27 may be the solution for the U.S. Navy and USAF as interim gap-filler aircraft. For the long term, there are several options:
Buy bare airframes made to specifications for completion in the U.S. Obtain a license to build Su-27s in the U.S. without export rights. Build some parts in the U.S. and buy major subassemblies from Russia for assembly in the U.S. (really a variant of the second option).
On the carrier version of the Su-27, both the wings and the horizontal tail fold. The authors argue that the Russian fighter/bomber can do the F-14s job at a fraction of the cost of a new, U.S.-built airplane (photo courtesy of Paul Gillcrist).
As a side issue in the procurement of these aircraft, the U.S. would certainly be funding a large part of Russias economic recovery, which would help to keep it stable and less of a threat. Obtaining a really good deal on Su-27s should be realistic and beneficial to both countries. It would also further cement the collaboration between Russia and the U.S. in the face of jointly perceived threats.
Action items!
Somebody (lets see some hands, folks) should carefully explore the procurement cost and fleet readiness implications of the proposals weve presented. Since were supposedly retired, this is something we can no longer explore without the help of a major agency.
As long as were asking questions about the future fighter programs, what about the JSF program? It is a joint U.S. Navy/USAF/USMC next-generation fighter program! (Heard that one before?) But this time, a dimly perceived USMC VTOL fighter is the objective!
Has anyone figured out that when an engine fails during hover, a twin-engine VTOL will do a rollover very quickly, thus preventing pilot ejection? Even Harriers require quick pilot action to avoid insidious, slow, roll-control loss if the nose was allowed to get too high in a crosswind hover. Many were lost. Thus, a VTOL for the Marines must be a single-engine configuration, which means that it must be a single-engine aircraft. It also means that the JSF will be another fighter in the 30,000-pound class (using the F-119 engine, for example).
Finale
You might wonder why we are taking these positions. We could talk about politicians, the specifics of current international events and future perilsof which we know nothing of substance.
What we do know is how we perceived the world unfolding as youngsters on December 7, 1941. Our leaders saw what was coming but were too late to achieve a high state of readiness. So, we listened to the radio and watched Movietone News in horror, grief and fear until our industrial capability at last turned the tide.
On the surface, the current world situation is not as threatening, but many world trouble spots may demand military attention via conventional forces and weapons. Events that do arise will do so quickly, leaving little time to build up the military. Our forces must be ready at all timessomething that seems to have lost its importance in the last decade. Tactical airpower must be refreshed in strategy and form, unencumbered by politics and corporate interference. In other words, well always need the ability to dash in, drop a lot of bombs and get out. If we dont do something about the impending vacuum of that capability very soon, we may find ourselves unable to effectively smack some dictators backside when he needs it.

U.S. Navy aircraft design comparisons
In the tables that follow, weve attempted to compare the fighter/bomber mission performance of the F-14D, F-18A, F-18E and Su-27. We cannot obtain or use classified U.S. Navy data. However, "Janes All The Worlds Aircraft" is presumably an accurate source of aircraft data. Tactical missions and loads differ from aircraft to aircraft, but an aeronautical engineer can extract some valid, nearly accurate comparisons and conclusions.
So here we go. We apologize for dragging you through the technical mud! Table 1 compares the F-18A, F-18E, F-14D, A-6E and Su-27 in the long-range fighter/bomber mission. In so doing, some fundamental issues of physics begin to emerge.
TABLE 1 F-18A F-18E F-14D A-6E Su-27 Weight empty (lb.) 23,832 30,564 43,879 27,888 38,580 Pilot and ammo (lb.) 535 535 838 500 500 Mm/no. of rounds 20/570 20/570 20/675 0 30/150 Internal fuel (lb.) 10,860 14,400 16,200 15,939 20,723 External fuel (lb.) 7,431 7,206 3,854 0 0 AAM (2); Sidewinders 472 472 472 0 472 No. of tanks/capacity 3/330 2/480 2/280 0 0 Bomb weight in lb. 4,000 4,000 8,000 8,000 8,000 Bombs: no. and type (2) Mk 84* (4) Mk 83 (4) Mk 84 (4) Mk 84 (4) Mk 84 Takeoff gross weight (lb.) 47,130 57,177 73,253 52,327 68,275 Takeoff fuel weight as % of gross takeoff weight 37.5 36.8 27.4 30.5 30.4 * Two 1,000-lb. Mk 83s used in Desert Fox, not 2,000 lb. Mk 84.
The message of Table 1 is that big is beautiful! The F-18A and substantially puffed-up F-18E dont carry much of a weapon load compared with the big guys. As you will see in the next table, they dont carry it very far either, in spite of their huge external fuel loads that prevent large weapon load-outs by using up wing store stations. Note the large takeoff fuel percentages: the big boys fly farther on less fuel, as Table 2 shows.
One caution in viewing these numbers; although they have been extracted from "Janes," aircraft companies are marvelously innovative at hiding the facts while appearing to be completely candid; weve been there. Further, for some numbers in the table and the tables that follow, we have made corrections to establish a common baseline.
Now that we have a common attack mission, lets address the mission performance and fundamental aero/propulsion issues. Table 2 clearly shows where "big is beautiful" comes from. Look at the radius multiplied by bomb-load factor (R x B). The F-14Ds and the SU-27s have twice the capability of the F-18s, so only half as many aircraft and crew need to be endangered (the bombs are twice as big and in-flight refueling is rarely needed). The mission radius comparison speaks for itself.
TABLE 2 F-18A F-18E F-14D A-6E Su-27 Store stations (2) 2,500 Same as F-18A (4) 2,000 (5) 3,600 (7) 2,000 (2) 2,350 Same as F-18A (2) 2,200 (1) 2,400 Same as F-18A (2) 1,800 Wing area (sq. ft.) 400 500 565 484 667 Wingspan 37.5 44.7 64.1/38.2 53 48.2 Sea level static afterburner thrust (lb.) 32,000 44,000 55,600 18,600 (*1) 55,100 Attack wing loading (bombs on board) (lb./sq. ft.) @ 60% fuel 100 98 115 94.9 90 Wing loading (bombs dropped) (lb./lb.) @ 60% fuel 90 90 101 NA 78 Attack thrust/weight (lb./lb.) @ 60% fuel .80 .90 .85 NA .92 Thrust/weight (bombs dropped; lb./lb.) @ 60% fuel .89 .98 .97 NA 1.06 Turning drag/lift factor 28.5 24.4 15.9 16.4 25.8 Attack-mission radius in n.m. 290 (*2) 390 (*2) 402 (*2) 500 (*2) 420 (*2, *3) Radius x bomb load (R x B); n.m. x lb./10^6 or 1,000,000 1.16 1.56 3.22 4.00 3.36 *1 No afterburner, *2 "Hi-lo-lo-hi" mission, *3 Probably low, NA=not available
Wing loading and thrust to weight require a bit more explanation. Wing loading at the attack-mission weight simply defines your predicament if you are jumped while carrying a full bomb load. After dropping the bombs, your wing loading is much better, as shown in the table; so is the thrust-to-weight ratio (T/W). Note that the F-18E and F-14D are nearly equal in T/W at .98 and .97 compared with the Su-27 at 1.06. The reason is that the weight of bombs dropped is doubled for the big guys.
The turning drag/lift factor is proportional to the span loading (W/b^2) at a given G loading and indicated airspeed (IAS). It is related to induced drag and is familiar to aerodynamicists. It is the dominant parameter in calculating sustained G. In air-combat turns, the induced drag at a given G level is directly proportional to the span loading. With its wings unswept below Mach .7 via the sweep programmer, the F-14s induced drag in turns is half that of the other aircraft tabulated due to its big span (squared). And aircraft combat maneuvering at the Yuma range proved that after the initial engagement, most of the time was spent below Mach .7.
Yes, I was thinking in particular of Alfonse D'Amato and his ridiculous posturing to keep the A-7 assembly lines on IIRC Long Island open, years ago. He was "a hero to his people", but I don't see old A-7 airframes groaning around Naval Reserve airfields the way we see Warthog-equipped ANG units being reactivated time and time again to go settle some armored camel-driver's hash for him.
Too, there has been some heavy politicking involving Texas aircraft plants, and I'm sure you know of some others. I suppose we're just fortunate that there were never any SPAD plants located in Bobby Byrd's beloved West Virginia.
So Cheney dinged our future naval-aviation needs in order to discipline Grumman and "teach them all a lesson". Now thanks to Clinton's policies, they're down to two companies, as you pointed out. I wonder whether Cheney's lesson took, or whether, in the long run, he and his successors can avoid future squeeze plays. After all -- capitalism is about Darwinism, and Darwinism is about a single winner.
Seems like there's no way we'll be able to avoid co-production or off-the-shelf deals with overseas design bureaus and manufacturers, in order to keep from getting juiced by the "survivors" ourselves. Which is a mark of a banana republic, but the more serious point is that you wind up separated from your sources of supply, and wind up having to defend an ocean and maybe another continent, just to keep your logistical train intact. Then, if we do a co-production deal and shoot the moon on producing content here, how do we turn around and tell Boeing that they can't let the Chinese do the same thing with the 777? Yuck.
Yeah, Grumman was "disciplined" all right. Don't know Cheyney's reasoning -- he may have had the whole deal misrepresented to him. There was a whole lotta lying going on in those days, and by the time the staff study got to the 5th floor E-ring, there is no telling who had been lied to or who was doing the lying.
Not to mention the Lobbyists who were hard at work to get the F-18 program started.
No version of the F-18 has or ever will meet the initial design specifications as to range, payload, speed, altitude or manueverability. When it is discovered that some aspect of the F-18's performance is below design spec, the spec is changed to reflect actual performance.
Sound familiar? "When your standards are too high, lower your standards!"
With that said...you seem to have a zeal for Russian weapon systems that could come in handy for me if I really want specs on the stuff they produce.
The Kamov is decent but the Apache can sit "behind" a mountain, Trees, Buildings and see & fire on targets on the other side of it without giving away its position to ground troops.
That is an everyday thing for the Apache.
The Kamov doesnt come close to that capability. If I am not mistaken...the Kamov needs a line of sight in order to engage ground forces or it needs a ground operator to laze a specific target in order for its missiles to engage.
It's producers have turned to Israel as well as France to spruce it up....that alone is telling.
It is a fine weapons/Recon platform.....for a second or third world country....but it isnt in the Apache's league especially not in the upcoming Comanche's.
It was the Apache that kicked off the air war in Iraq by slipping in under Iraqi Radar and attacking an Iraqi Radar/CC station located in southern Iraq and opening a door for our conventional Aircraft.
Strictly speaking, the "Flanker" isn't a Russian design, but rather a Russian copy of the Iranian F-14A the KGB got them. Hence the sobriquet, "Tomcatsky".
That's why it so closely resembles the Tom in size, performance, and appearance, and why it's such a good fit to replace the F-14D's Cheney and Grumman screwed us out of.
Load a "Flanker" up with F-14 avionics, and you've essentially got a fixed-wing Tomcat.
Again i fear you may have misconstrued some of my posts. I believe i clarified myself on the Hokums position in that it is the 'best' (and the word best is always relative) when it comes to matters of cost effectiveness (the ability to perform the same or similar duties at the same level of efficacy, yet at a cheaper economical or logistical cost). In that respect the Kamov is spectacular.
Secondly the fact that Israel and France has been participating in the development and upgrades of the Kamov do not mean it is deficient! The KA-50-2 Erdogran produced by the IAI was simply to fit the Hokum with Nato weapons, and a cockpit customized for the Israelis! That does not mean the Kamov was lacking, just that it wasn't equipped to utilize Nato weapons just Russian ones, and the cockpit was Russian!
And as for your assertion that the Ka-50 is relegated to use by bottom tier countries is not entirely correct, unless you consider Russia among the dregs when it comes to military power. The Russians may have undergone several major changes, and even their military is not what it use to be as is still undergoing a paradigm change to make it more efficient, and leaner, than it used to be during the Soviet era. However it is definitely not a walkover military state. And the Kamov has been quite efficient in chechnya, especially in 'cauterizing' areas that are bristling with AA missiles since the Kamov can utilize its low acoustic, radar and thermal signatures to penetrate those defenses, or destroy them.
However again i am not posting this to start a whole 'The Apache is Better Than The Hokum....and So is the Comanche!' I think the AH-64D is a work of art aesthetically, and also one dang great tank killer. However that does not mean the Kamov, Eurocopter tiger, or even the quite impressive South African Rooivalk is suddenly null and void.
And the Kamov is not as 'basic' as you imply. The versions in use by the Russians can perform to the same specifications as a LongBow Apache. To almost an uncanny degree (i guess that is why some people claim the Russians reverse engineer American military concepts....and sometimes even the actual models in a number of cases).
And this brings me to the Comanche. The comanche is definitely an amazing concept since it brings the element of reconnaissance/attack helicopters to a whole new plateau. However i have gotten wind of some 'oligarchs' in positions of power in the military and congress who have been trying to oppose this project. To the best of my knowledge the Army put orders for around 1000 RAH-66s , starting from around 2007. And i know for certain it has finished several importan milestones.....including i believe starting the EMD (where they start seeing its true capabilities). Still the program remains in perpetual jeopardy (until the day the army actually get their mits on it) due to some people (who by the way in the event of combat will be safe and sound at home and not in active warfare) who are trying to kill in in vitro! Why are they doing this? Take your pick from a number of choices, but the bottom line is that the RAH-66 has come extremely far, but you could well say the sword of damocles hangs over it. I hope it makes it through, but that question will be 'completely'answered some time in the near future.
Could not help myself, and once i discovered how to post pics on this forum i just took to it like a duck to water.
However i am glad you liked them.
Low and slow is the problem with the A-10, even though it is a mean machine. Years ago, one of the pilots told me it was designed to kill a massive onslaught of Russian armor into western Europe, but the pilots knew it was a suicide mission due to the proliferation of man-portable AA missiles. In fact, the A-10's and the British Tornadoes were both pulled back from ground attack missions early in the Gulf War. I don't remember if we lost any Warthogs, but the Brits had 2 or 3 Tornadoes go down, and that's one expensive airplane. Good pilots are very expensive too. Looks like standoff weapons are the wave of the future.
I'd love to have a 56K connection.....our neighborhood is stranded on a 35-year old "pair gain loop", a juryrig lashup that SW Bell has used for years -- top datarate over one of those is stuck at 26.4K, half the usual rate. A woman living five blocks away outside Purdah gets 48-49K every time. :^ \
Say whut ?
Isn't that a French munition...or rather, submunition?
Say whut ?
I didn't get that either. I thought maybe he shot over my head with that post. Glad I'm not the only one...
