I saw a PBS special on the X-plane competition between Boeing and
Lockheed for the Joint Task Force (JTF) fighter; the jet of the future. I think the whole thing was a total waste of money, and that by signing off on this competition the Pentagon has doomed America to a useless arsenal. Boeing's plane was so heavy they had to remove panels before it could even hover. Neither aircraft could stay in the air more than half an hour without refueling (Boeing's Navy style in-flight refueling system was not operational and so they had to land every half an hour to refuel). Neither plane had any armaments or weapons during all of this. The problem is that the Pentagon requires the JTF to be vertical take off/landing capable. By doing so they are requiring 25% of the aircraft to be devoted to the necessary systems; in the case of the winning Lockheed aircraft, a huge fan in the middle of the fuselage. Granted, it's an elegant engineering accomplishment but it has zero combat effectiveness. Requiring all jets to be built by these standards is suicidal because it reduces the range and payload of every attack jet. It's really depressing to me that our military planners have come up with such an idiotic plan and that neither Lockheed or Boeing made the slightest objection. Clearly they are not American companies any longer but multi national corporations whose sympathies belong to the highest bidder. Bill Clark, P.E. |

Incorrect only ONE variant of the 3 offered has VSTOL and only that variant has the fan. Granted, it's an elegant engineering accomplishment but it has zero combat effectiveness.

I think the whole thing was a total waste of money, and that by signing off on this competition the Pentagon has doomed America to a useless arsenal. You apparently are talking about the JSF, Joint Strike Fighter. They are currently in the prototype stage, with the X-32 and X-35 recently having competed in a fly-off. The Lockheed X-35 won the competition, but in reality, these planes are so complex that parts come from all over the aviation industry. Boeing's plane was so heavy they had to remove panels before it could even hover. Neither aircraft could stay in the air more than half an hour without refueling (Boeing's Navy style in-flight refueling system was not operational and so they had to land every half an hour to refuel). Neither plane had any armaments or weapons during all of this. Keep in mind that these were PROTOTYPES, hense the experimental X- designation. Once a winner is selected, they then go to full scale development, which are Y- designations. That could take a number of years, and the final plane might look very different from the prototypes. Look at how much changed between the YF-22 and the F/A-22 that finally emerged. Dittos for weapons, that comes in the Y- program. The problem is that the Pentagon requires the JTF to be vertical take off/landing capable. By doing so they are requiring 25% of the aircraft to be devoted to the necessary systems; in the case of the winning Lockheed aircraft, a huge fan in the middle of the fuselage. I think you mis-understand what is going on. There are a number of different versions of the JFS. There is one for the US Air Force, a variant for the US-Navy, and a 3rd variant for the Marines. In addition, foriegn powers are starting to sign onto the program. For example, the UK has agreed to pick up the Air Force variant. Each of these variants has a different mission, and a different internal configuration. The Air Force and Navy versions do not have the vertical take off mechanism, only the Marine version does. That version is designed to replace the Harrier. As you know, the Harrier has rather short legs, too. When you hover, the ability to hover is not needed for a very long time. If you stay in one plane, you become a juicy target. Granted, it's an elegant engineering accomplishment but it has zero combat effectiveness. Requiring all jets to be built by these standards is suicidal because it reduces the range and payload of every attack jet. It's really depressing to me that our military planners have come up with such an idiotic plan and that neither Lockheed or Boeing made the slightest objection. Clearly they are not American companies any longer but multi national corporations whose sympathies belong to the highest bidder. I think you misunderstood what the whole program is about. Please do some reading on the net, or pick up a book or magazine on the topic. You will learn that this is actually the low cost airplane of the future for all of our armed forces, and many of our allies. -john- -- ================================================== ================== John A.

Just a little clarification - the UK is actually a development partner having funded something like 25% of the programme so far as well as having design input (both RR & BAE have a lot of experience in the field). My understanding was that we had announced selection of the STOVL (similar to Marine) verion as our Harrier replacement. Additional countries such as the Netherlands, Italy, Denmark, Canada, Norway, Australia and Turkey are all signing up to the programme. |

Look at how much changed between the YF-22 and the F/A-22 that finally emerged. Dittos for weapons, that comes in the Y- program. Adding a bit here... they X- prototypes were not intended to be representative of the final production versions. Aerodynamically, maybe (and not even that in the case of the Boeing design), but their fuel capacities were far below what an operational aircraft would carry. Also, the weapons are pretty much standardized (most everything that's in the inventory now), and testing them with a pre-development aircraft is pretty much useless. The big issue will not be whether the aircraft can talk to or emply the weapons so much as separation and clearance and such... and that wouldn't be too much of a problem. Avionics interface testing can be flown on other testbeds or on the preproduction aircraft. As stated above, the two ATF prototype aircraft were only somewhat similar to production aircraft. Neither of them carried radar or an operational amount of fuel, and neither were equipped to use weapons (though a dummy round was test-launched from the YF-22). |

![]() neither Lockheed or Boeing made the slightest objection. Clearly they are not American companies any longer but multi national corporations whose sympathies belong to the highest bidder. Companies build what customers want. I haven't heard NBC and CBS complaining that Americans want to watch "Friends" (whatever) when it's complete dreck. all the best -- Dan Ford email: www.danford.net/letters.htm#9 see the Warbird's Forum at www.warbirdforum.com and the Piper Cub Forum at www.pipercubforum.com |

I suspect a few FAA[1] pilots might have disagreed regarding the combat effectiveness of the VSTOL Harrier. Requiring all jets to be built by these standards is suicidal because it reduces the range and payload of every attack jet. Most F-35s won't be built with the VTOL fan. I expect in the others, the space will be used for extra fuel. It's really depressing to me that our military planners have come up with such an idiotic plan and that neither Lockheed or Boeing made the slightest objection. ****ing off one's largest customer isn't usually good business sense.
