There have been significant technological advances in two metre band counter stealth radar, passive emitter locating systems, infrared sensors and high power-aperture X-band phased array radars. Moreover, DRFM jammers are proliferating, and Flankers now have the option of towed decoys like the KEDR, both diminishing the effectiveness of the AIM-120 AMRAAM which is to arm the Joint Strike Fighter. For all practical purposes, technological evolution has rendered the concept of the Joint Strike Fighter obsolete before it has even completed Flight Test or entered full rate production. This is a clear case of failed technological strategy on the part of the Joint Strike Fighter planning staff. It is now abundantly clear that the Joint Strike Fighter is not going to be viable in Beyond Visual Range air combat, just as it was clear from the outset that it would never be a serious player in Within Visual Range air combat. Improvements in the capability and number of internally carried missiles will not turn this problem around, since the opposing sensor and weapons capabilities will continue to evolve over time. The remarkable claims about Joint Strike Fighter air combat performance made recently by the program executives and manufacturer's public relations staff can be explained only if the cited simulations were conducted against 1980s Sukhoi variants, devoid of the capabilities of contemporary and future Flanker variants.
