Inside the Joint Strike Fighter Competition 375
jonerik writes "The June issue of the Atlantic Monthly has this account of the history of the Joint Strike Fighter competition between Boeing and Lockheed Martin (which the latter company ended up winning this past fall, with Boeing now touting its expanding line of unmanned aircraft as the true future of tactical aviation). The article does a fine job of showing how the competitors dealt with the challenge of producing an aircraft (now dubbed the F-35) that the Air Force, Navy, Marines, RAF, and Royal Navy could all live with. Funniest part: Boeing's X-32 entry, with its enormous pelican-like jet intake, had some questioning whether the plane's bizarre appearance didn't hurt its chances more than its performance. 'Helpful as my contacts at Boeing were, no one was eager to claim credit for the design of the plane,' says the article's writer James Fallows." Fascinating article.

Former Yakovlev employees accuse Yakovlev heads of taking personal interest out of the deal with Lockheed, because the official sum of the contract did not correspond with the value of the information presented to the US company. The data was on the Yak-141 test program, aerodynamics and design features, including the design of the R-79 engine nozzles.
After a careful study of those materials, Lockheed - without much noise - changed its initial JSF proposal, including a design of the engine nozzles that is now very similar to those of the Yak-141...

The LM X-35 [optushome.com.au]
It seems the LM X-35 looks a lot more like the Yak-43 than the LM's canard foreplane CALF/JAST prototype. Basically the differances are a more stealthy body, uncanted wings & a lift fan rather than a lift jet. Funny thing is back then in the early 90's the Soyuz Engine Company was right in the process of designing a shafted lift fan to replace the old Rybinsk lift jet setup. I won't even start on the vectored rear nozzle setup on the P$W 135 engine which appears to be an exact copy of the Soyuz R79 (ie I'll save the nozzle pics for another day).

a pilot. Even with these demands uppermost, fighters turn
out to be sleek, beautiful and frightening beasts.
The Boeing design is very strange-looking. The air intake

how disgusted the maintenance crew will be? How would it perform

If you have one of these parked on an aircraft carrier,
how many times would seagulls see the gaping hole

Considerations (or trolls if you wish) like my previous paragraph will
surely have an effect on the selection process. And
all because the aircraft looks ugly. Besides, did it ever occur
to you that the Lockheed design performs better therefore
it looks better?
I don't think there are plastic fighters out there.
Plastic may be light but it has a very low melting

The Marine Corps version can take off vertically - go supersonic - then land vertically at the end of the mission.

This will probably be the last manned fighter that the U.S. builds. Drones are cheaper, don't put a pilot at risk, and can make more violent maneuvers than any manned airplane - eventually they'll take over the air.

The Avenger is the only fighter gattling gun that retains its brass for recycle after the slugs are fired.

Many joke about the GAU-8 being designed first, with the airplane built around the gun after.
Aside from the jokes, the gun is also very effective in aerial combat against helicopters or fast moving fighter jets getting too close and slow. The gun is deadly accurate and feared by enemy tank commanders worldwide. The gun's performance was demonstrated thoroughly during Desert Storm at the able hands of Hog pilots. The highly maneuverable and agile A-10, combined with the GAU-8, is a force to be both feared and reckoned with on the battlefield.
The avenger could probbably put a few holes in the hull of a carrier, but it has no chance of sinking it, and no chance AT ALL of getting close enough to hit it. All US Navy ships have at least one of these bad boys (from Raytheon's website):

You're confusing some of the performance characteristics of the ATF (which turned into the F-22 Raptor) with the JSF (the now F-35).
The F-22 is a high-performance, air-superiority fighter intended to superceed the F-15. It has a 2nd-gen stealth (very low radar cross-section and low observability infrared/visible features) design, coupled with a high speed (~ Mach 1.4 without afterburners, ~2.2 full burner), and is primarily a missile-platform (ie, no bombs). It is the premier air-superiority fighter in the world.
The F-35 is a ground-attack AKA strike fighter (NOT a close-support aircraft). It tops out at about Mach 1.5 or so at altitude, and is not anywhere near as stealthy as the F-22 (though much, much better than the F-16, F-15, or F-18). One version will have VSTOL cabilities. It carries laser designators and other ground-attack sensors, and has a modest bomb-load (though smart weapons will be it's primary payload).
All things said, the F-35 is a good design, and a reasonable compromise on cost, performance, and advanced technology. HOWEVER, it is NOT an air-superiority fighter (though the Royal Navy will use it as such off their carriers), neither is it a dedicated close-support aircraft (though the US Marines will use is in such a roll). It is primarily a multi-role strike craft. It's really a blend of the features of the F-18, Harrier, F-16, and F-22, with some compromises.
The A-10 will probably remain the best close-support aircraft around for general use (the Harrier and similar craft are superior, but only in specific uses), and the F-15 and F-14 (and of course the F-22, plus the MiG-29) are better air-superiority fighers.
My major concern with the F-35 is the low payload cability compared to the F-16/18 (though it's superior to the Harrier). It's probably OK, since it looks like the "bomb dumptruck" role of massive dumb firepower is being relegated to the B-52 bomber and AC-130 gunships these days.

Furthermore, with some exceptions, doing the testing and development on upgrades and parts replacements will also be cheaper for the life of the plane.

In particular, the Boeing design uses conventional hydraulics for actuating its various parts, but the LockMart plane uses an electrical bus to distribute power to motors that actuate the various parts. It turns out that while the two systems weigh about the same and perform about the same, there are second and third order effects that favor the electrical bus:
While a hydraulic system is constantly under pressure, which means pump motors run constantly and heat must be constantly dissipated, the electrical bus just sits there while you aren't using it. So the power systems and cooling systems for the LockMart plane don't have to be as heavy-duty as the Boeing plane. And you can make an electrical bus redundant more easily, just by running extra cables, much easier than making hydraulics redundant. And think how much easier it will be to repair and service an electrical bus compared to a bunch of heavy-duty hoses and pipes full of hydraulic fluid!

The very wide-chord wing of the Boeing design is good for a number of structural, aerodynamic, and stealth reasons. Unfortunately, Boeing elected to change the design for the actual plane to a separate tail, rather than the delta wing -- Lockheed partisans claimed (rightly, IMHO) that this meant that the demonstrator that Boeing flew wasn't really representative of the final plane.
The one terrific thing that the Lockheed design has, the one true aerodynamic innovation, is the bump intake. There's a big bump right in front of the intakes on the Lockheed plane; it performs all of the functions of the typical intake splitter plate, purging the boundary layer, with a far more elegant, lighter, simpler, stealthier, easier-to-maintain design. Hats off to the engineers that came up with that.

Look at the B-2. I don't think anyone could say (with any amount of seriousness) that it is ugly. The plane serves its purpose even while sitting on the ground. We only have 19, not really enough for a full-scale war, yet they still work as a deterent. You don't have to know what it is to be scared of it, if you know it's gonna come after you.
Being 'scared' of military technology is all part of the game. Boeing could not produce a scary looking aircraft, so they lost.

The LockMart JSF, on the other hand, was designed more as a conventional fighter with the VTOL added on.
Only the Marine Corps were really interested in VTOL, and given that they would have only bought tens of aircraft (as opposed to the thousands the Air Force was looking for), the Air Force had much more sway. So LockMart correctly wooed the Air Force with fighter performance as the priority.

1. Build aircraft that support a fragile and expensive pilot and be limited from a design and performance stand-point
2. Build UCAVs that have the same level of reliability as 1950s and early 60s jet fighters, and leave the pilots out of the loop and safe at home.
While the remote aircraft idea isn't new, the technologies involved are at the point where it is a do-able product. And right now, the UCAVs in the United States have about the same level of reliability as the single engine jet fighters the Navy and Air Force had up to the Phantom came into service.

Think "remotely piloted fighter aircraft."
Sure, such craft could be used as computer controlled drones but the real benefit is going to be when you have squadrons of these piloted by top-gun pilots sitting safely away from the action.
If you were a fighter pilot would you care to engage in a dogfight with a remotely piloted aircraft that could pull more G's than you could? That could pull off manouveres that would literally break a pilot's neck? Or that could simply be made to explode like a SAM if you got too close it?
Would you like knowing that even if you shoot one out of the air the remote pilot is simply going to say "Dammit! He got me! Lets see if he can do it again." and then he is going to select and take over control of another one of a trio of inbound RPVs under computer control heading to your location and use it to try to kill you again?
I don't think any fighter pilot would like to face such remotely piloted craft. Chances of survival against them would be slim. Especially combined with new missle technologies that allow missles to be fired at targets behind and alongside of aircraft.

Initial gut reaction: this would provide too much power -- power that would obviously bring the most benefit to those who would use it most (and therefore those who would deserve it least). Seems like we'd end up with either Hitler/Stalin type of totalitarianism, or gangster/warlord type chaos, depending on how hard it was to gain access to this weapon.
If *everyone* could easily use this weapon, then I suppose it's possible we'd end up with a cold-war-like detente, where everyone is afraid of offending anyone else. It wouldn't last very long, though. Someone's bound to start the explosion sooner or later. Fear of retailiation can supress hostility, but it can't establish permanent peace.
The scariest part of a weapon like that is that it lets people do violence without risk to themselves. I don't know if facts would back me up on this, but I tend to think that war was better (i.e., more horrible, hated, and avoided) when the people deciding to do violence to others bore the primary risks, rather than delegating those risks to underlings. Things sure seem to be moving in the opposite direction, though.

Your point was probably valid until the 1990's. The situation is a little different today, however.
Avoiding conflicts: Right now, conventional wars in developed countries are probably suppressed primarily by the advent of cheap handheld video cameras, satellite uplinks and cable news networks. The public just won't stomach live carnage on their TVs perpetrated by traditional governments, so the pressure to avoid or end old-fashioned wars is enormous (at least when the corpses appear to be middle-class or higher).
A-bombs: As in any aspect of life, you have to multiply the risks by the expected benefits to determine the utility. Until the last decade, nuclear weapons were tightly controlled by less than ten powerful governments. Risky, but you could at least hope that all of the players were somewhat rational. Today, additional players and potential players are on the field, some of whom may not respond to the traditional concept of deterrence.
At least these new players don't have very much megatonnage (yet). For now, this means that while the risk of worldwide nuclear destruction has decreased with the end of the Cold War, the risk of millions being killed in a terrorist attack or a nuclear exchange between smaller countries is much greater than ever before.
With nuclear weapons, wouldn't take much of a mistake to invalidate your assertion.

This means that the border between peace and war becomes very fuzzy -- now the fuzzy area is when "militants", "rebels" and "separatists" are fighting somewhere and being blamed (right or wrong) on someone else's government, but with unmanned weapons something that otherwise would be considered to be an act of war will become perceived as harmless fight. At this point in history the only "unmanned weapon" widely deployed is a nuclear missile, and launching it is an unambiguous act of war. But messing around between two fleets of unmanned fighters will be something like subs of hostile to each other countries chasing each other -- except that subs still don't fire at each other, and fighters can without actually endangering anyone.
It's all nice and dandy when the government of the country that believes that it has a god-given right to police the rest of the world and also god-given exclusive ability to develop technology is planning yet another weapon. Few years later when everyone, his brother, his dog, his son's bully and his ex-girlfriend has the same weapon, all the government can think of is "non-proliferation" bullshit.

Of course you're right, but you're also overlooking something. The downfall of remote operations that will remain, after the engineering has been done, will be vulnerability to jamming. Oh sure, against third world forces these toys are impressive, but against an enemy with a noticeable electronic warfare capability the usefulness of remotely operated platforms will stay limited for the conceivable future. There has to be some signal carrying the data between the remote and the operator, and signals can be jammed.

or even a simple one really.
although movies may have you believe that you can push a button in front of you on your Star Wars (tm) land speeder and "jam" the entire electromagnetic spectrum, in practice it takes a wee little bit more than that.
The US can conceivably do it but often we don't really bother. The infrastructure would be a nuisance. Jamming radar is easy and useful. Jamming comms is a real pain in the ass. Even if some magic antenna were created that would radiate immense power to jam all possible frequencies the enemy might use, then you have the slight problem of 1. microwaved technicians and 2. you just screwed yourself out of any chance of communicating with your own people.
In order to be effective, you have to have a signals exploitation system/team/whatever. They have to find and identify the frequency you need to target. And they need to do so in time to have it actually do any good. Then you need to have the jamming equipment to deal with that frequency band. And you have to be able to broadcast towards the target with more power than the base station you are trying to block is capable of reaching the target with. Sending a puny signal to block a strong one obviously wouldn't work. You also need to have your jamming antenna last longer than 2 or 3 seconds. And the US Military has electronics warfare people who take almost child-like delight in smashing other peoples antennas with Anti-Radiation Missiles. Just ask any Iraqi who pushed the "send" button on anything larger than a walkie-talkie back in the Persian Gulf Ass Kicking Festival. The reason he won't answer you is because he's dead. And that was over 10 years ago. Our missiles haven't been sitting around getting arthritis, they're faster, more accurate, blah blah blah. You could even have a nice big fat UCAV with a halfassed AI and a whole pile of HARM missiles, doing nothing but flying circles and transmitting on the same frequency, just to get someone to turn on the jammer. A transmitting antenna is screaming its own position to a HARM missile, they really don't even need a targetting system.

The F-35 will have variants for all the branches of the military as well as foreign militaries. The F-35 will use much of the technology developed in the F-22 program (started prior to the F-35) and will save the government quite a bit of money as it uses standardized components.
More than one aircraft is necessary because they can perform different jobs. Just like the navy has more than one kind of ship, and the army has more than one kind of land vehicle.
