The Pentagon is stopping work on an new engine for the Air Force F-35 fighter jet. This engine was designed to be a back-up. The reason is because of money. The stoppage is expected to last for 90 days. There was no money included in President Obama’s budget proposal for the next fiscal year for the project. But budget deliberations continue. Congress is split on the project. Some like, some don’t. GE and Rolls Royce are the contractors.
