Interesting article that looks at the ongoing costs of utilizing the F-35.

An article from 1984 that talked about the development problems of the F-18 that made it develop cracks and limited how the fighter could fly

		| Mr.  Snyder said that although these vortices are violent enough to have  caused cracks in the F-18's twin tail assembly, they do not adversely  affect the pilot's control. ''Pilots are aware of something going on,''  he said of the buffeting action. 
 
 Until  the F-18's are fixed, a McDonnell Douglas spokesman said, they will be  limited to climb angles less than 25 degrees above horizontal and dive  angles less than six degrees below horizontal. At altitudes higher than  30,000 feet, however, there are no such restrictions because the  vortices are weaker in thin atmosphere.   Less Development Money
 
 
 Asked  why the problem had not been discovered early in the project, Mr.  Snyder said that ''there was a real squeeze on development money''  because of the existence of a prototype aircraft. He said the prototype,  designed by Northrop in the late 1960's and called the YF-17, was used  to acquire the kind of stress information that might otherwise have been  obtained from testing F-18 models in wind tunnels, for example.

I also want to kind of state that when people talk about the development problems on the F-35, which by the way is the most complex aircraft ever made, they tend to forget that the development of the F/A-18 was fraught with a similar story line.  
A article that talks about the development of the Onboard Mission library and how it works to fight the aircraft

		| Consisting of hardware and software, the mission data files are  essentially a database of known threats and friendly aircraft in  specific parts of the world. The files are being worked on at a  reprogramming laboratory at Eglin Air Force Base, Fla., Air Force  officials said. The mission data files are designed to work with the  aircraft's Radar Warning Receiver engineered to find and identify  approaching enemy threats and incoming hostile fire. Pleus said the service is working vigorously to speed up development  and integration of new software engineered to widen the threat envelope  of the mission data files to enable the now operational F-35 to better  identify specific enemy threats.
 
 
 
 While progress at the Eglin laboratory has been steady, the  integration of the mission data files for the F-35 have experienced some  delays, prompting the current effort to quicken the pace so that the  operational aircraft has the most extensive threat library possible. The  first increments of the technology will be integrated for training  F-35s, Pleus explained.
