The deal includes aircrafts to be manufactured for the U.S military, Britain and other allies and will reduce the cost of the radar-evading warplane by around 3 percent. Sources said that the cost of U.S Air Force model of the jet will lower by around 4 percent.

Lockheed has delivered 23 jets out of 36 which were due this year and the company said they plan to deliver the remaining ones within due time.
