Another Flight Global article on the F-35.
Brief snip from the article:-
Production of the F-35 Lightning II is on course to make its latest rate rise this year, after Lockheed Martin met its contractual target to deliver 91 of the fifth-generation fighter during 2018.
Detailing last year's delivery total, Lockheed says a combined 54 aircraft were handed over to the US Air Force, US Marine Corps and US Navy, while 21 went to partner nations. The remaining 16 were shipped to Foreign Military Sales (FMS) programme customers.
Lockheed has hailed its achievement of the 2018 delivery target as "demonstrating the F-35 enterprise's ability to ramp up to full-rate production". "Year-over-year, we have increased production, lowered costs, reduced build time, and improved quality and on-time deliveries," notes Greg Ulmer, the company's general manager of the F-35 programme.
