Subject: Raptor Follies From: Chuck Spinney <cspinney@erols.com> [Personal opinion, not representing institutional affiliation] Fri, 10 Apr 1998 This attached article by George Wilson describes how far the Pentagon will go to avoid realistic testing. The F-22 Raptor is the most technically challenging fighter development program conceived to date. The Raptor was put into concurrent engineering and manufacturing development (EMD) in the Summer of 1991, after claiming the the flight tests of the YF-22 showed that it was ready for EMD. But the YF-22 was not a true prototype, because it did not have any mission avionics or stealth technologies--and it used an underpowered engine. The YF-22 is more accurately characterized as a supersonic cruise demonstrator. After demonstrating supersonic cruise capability, the logical engineering approach to reducing technical and economic risks would have been to build and test mission-capable prototypes. In 1991, I wrote a report arguing for a this approach rather than proceding directly into concurrent engineering and manufacturing development, or EMD. But EMD was a more attractive option politically, because it allowed the contractor to reduce his political risks by spreading subcontracts and production facilities around the nation. In effect, the EMD decision traded off lower political risks for higher technical and economic risks. (This report was in my message of 3/26/98). As this article shows, the AF now wants to reduce political risk even further by rushing the F-22 into production before the flight tests of the EMD aircraft have demonstrated its stealth capabilities or the effectiveness its mission avionics. Many people believe the riskiest part the F-22 program is its integrated avionics. But these avionics are not even installed in the early EMD aircraft, yet these aircraft were originally conceived as the pre-production test vehicles. EMD Aircraft #4, for example, will have the radar, but not a complete suite of avionics and software. Moreover, #4 will not be delivered until AFTER the production decison. According to an 18 February 1998 briefing by Randall Shumacker (Information Technology Division of the Naval Research Laboratory), the software of the F-22 will require almost three times as many instructions as the B-1 bomber, and four times those of an Aegis Missile Cruiser. No one has ever built and flown a suite of integrated avionics anything like those of the F-22. Avionics systems now flying--like the troubled defensive avionics of the B-1--are easier-to-design "federated" architectures. So, even when all the integrated avionics are installed, it will probably take a long time to debug the software and make the component functions work together harmoniously and correctly. Why would a production decision take place before the first full capabity EMD test aircraft is even delivered, let alone tested? There is no military risk to justify such a reckless rush to judgement. On the other hand, a such production decison would reduce political risk even further, because it would increase the pressure on Congress by magnifying the number of F-22 related jobs as well as the profits in companies located in hundreds of congressional districts around the United States. So we come full circle: After spending billions of dollars on development, we are about to do a rerun of the 1991 decision. This situation is now so preposterous that, that the liguistics of George Orwell are being invoked to rationalize the situation. According to Wilson's report, the AF wants to re-name the first production F-22s to "pre-production test vehicles." If this is correct, acquistion reform has mutated itself into an circular decision-making logic wherein we call a "demonstrator" a prototype to skip the prototyping phase, then build the pre-production test vehicles in a concurrent EMD program, which makes it easier to lock in an eventual production decison by spreading subcontracts around the nation, then we rush the program into production before testing of the full-up pre-production vehicles has even begun, and finally close the circle by having the temerity to call the production vehicles "pre-production test vehicles." This is political engineering run amok. With decison making like this, it should be no surprise that that a cold war budget can not support a post cold war force structure, without shortages of spare parts, rising rates of cannibalizations, shrinking forces, aging equipment, and most importantly, declining rates of training and retention among the warriors and maintenance troops at the end of this food chain. Coming on top of the pre-mature production decision that lies at the center of the F/A-18E/F wing drop fiasco, one would have hoped decison makers would err more on the side of caution. But if Wilson's reporting is correct, it looks like this will not happen in the case of the F-22. At least we named the F-22 correctly--a raptor is a dinasaur. -------------------------[attachment]------------------------------ Pentagon Plans to Put F-22 Into Production -- But Will Call It a "Test" By George C.
