The Joint Strike Fighter Cooperative Avionics Test Bed (CATB), a 737-300 aircraft extensively modified by BAE Systems, successfully completed its maiden flight at Mojave, CA, following an effort that as lasted nearly 3 years. The "CAT-Bird," is a flying test bed that replicates the F-35 avionics suite; among other things, it will be used to verify "sensor fusion" - the F-35's capability to collect data from multiple sensors and fuse it into a coherent situational awareness display.
