Performance compromises in specialized roles are already quite obvious in the close air support, or CAS, mission where the F-35 purports to replace the Fairchild-Republic A-10 Thunderbolt, or Warthog.

As a fighter-bomber design, the F-35 is inherently too fast to find targets on the ground independently -- that is, without being cued directly to the intended target with external assistance. It is too limited in range, duration, and weapons payload to persist in the air over ground combat areas, and too thin skinned and delicate to survive tactical air defenses typical on the conventional battlefield. The absence of a more serious air to ground cannon, such as the A-10's GAU-8, even further limits the F-35 in the close air support role.

Similarly, F-35 performance in comparison to existing aircraft in other fighter or bomber roles will remain fundamentally unknown unless and until there are serious side by side flight test comparisons in specific mission tasks with existing aircraft such as the F-117, F-15E, F-16 and F-18.

Such specific side by side tests are, however, not included in the inadequate F-35 test plan. Just as in the case of the A-10's specific mission, there may well be too many negative trade-offs to achieve the multi-role design of the F-35 to make it an effective, let alone affordable, replacement for existing aircraft in the missions now addressed by the F-16 and other aircraft. Only large amounts of rigorous testing and honest reporting will tell, but we may never know until it is very much too late.

Actual performance of the F-35 is currently unknown, and it will remain so for a long time to come. The U.S. Air Force, Navy, and Marine Corps are now rushing to pay for production units before they know just what it is they are going to get for their money. Initial operational testing is expected to run through 2013, at which point a planned 275 production aircraft will have already been delivered to the Department of Defense.

This is an even worse degree of concurrency than the F-22, which evidenced multiple performance compromises, even structural problems, deep into its acquisition. However, the F-22 had many more hours of developmental test flying under its belt when the first aircraft were delivered to the Air Force than will be the case for the F-35.

In fact, data now being generated on F-35 performance are not even being provided by a production representative aircraft, which has not yet been delivered. This plan to acquire significant numbers of production aircraft well before the completion of operational testing has been the subject of significant criticism by various parties, most prominently the Government Accountability Office. And, according to recent media reports, the test phase may be truncated even further by reducing yet again the number of test flight aircraft and the number of hours they will fly.

Congress rejected DoD's requests in FY2007 and FY2008 to cancel funding for a second F136 Alternate Engine produced by General Electric, adding $340 million in the FY2007 budget and $480 million in FY2008 defense bills to continue the Alternate Engine program. While some discount as "pork" the efforts in Congress to continue this second engine program, it is also notable that the history of engine development for the F-14, F-15, and F-16 shows an advantage to having a competing design available.

It may be that for some, perhaps all, missions, the JSF is a significant performance step backwards, but one that comes at great cost. As a result, the JSF program may be more a threat to the U.S. military's efforts to modernize its tactical aviation capabilities than a solution.

Whatever value the JSF program might have is that of a technology demonstrator, for which production of more than a very small number of test samples is unnecessary. If the program can demonstrate significant performance advantages over existing designs, at anything even approximating its yet-to-be determined but substantially higher costs, there may then emerge a reason to proceed. The absence of any known major counter-air fighter threat from a competing air force means that there is certainly no need to rush into buying a "pig in a poke."

The F-35 is a classic case of the longstanding problems in our weapons procurement system. Unrealistic promises for cost, performance, and maintainability are made; no one in DoD or Congress performs real oversight of the "buy-in" assertions, and a material and political commitment is made to the program.

Once the latter is accomplished, the real acquisition costs and performance compromises inevitably become manifest, at which point a rational decision is opposed by the politicians in the Pentagon and Congress because the entire camel is already in the tent.
