Once it became clear that the Jane 2.0 platform was unsuitable for long-term deployment, the United States Army authorized a replacement. As is often the case with software development, Jane 3.0 had been in development since before Jane 2.0 had been finalized. The programmers had seen all of the problems of the previous program in the field and taken great effort to avoid them in Jane 3.0. The final version of her code was in many ways a step backward. She was designed not to adapt as her older sister had been, but instead relied on preprogrammed tactics and strategies. She was not as powerful but exactly what the army needed at that time.
