World's costliest fighter jet - $276 Billion financed by US and other 8 Nations

The costliest international warplane project, the F-35 Lightning 2 Joint Strike Fighter, securely completed its first test flight this month, advancing a $276.5 billion program financed by the United States and eight other countries.

The company is developing three models of the radar-evading, multirole fighter jet. The United States’ and the partners involved in the project are Britain, Italy, Netherlands, Turkey, Canada, Australia, Denmark and Norway. Singapore and Israel are also involved but have not devoted funds yet.

The jet climbed to 15,000 feet with high speed. Two F-16s and an F/A-18 served as escorts to the “successful inaugural flight,”.

Two separate, interchangeable F-35 engines are under development — one built by United Technologies Corp.’s , the other by a team of General Electric Co.and Rolls-Royce Plc.
