The first F-35 Lightning II for the UK, an F-35B STOVL model, just made its first flight and Lockheed Martin released a video of the event:
The UK originally planned to purchase the F-35B and they ordered two aircraft from LRIP (Low-Rate Initial Production) – BK-1 & BK-2. They later decided to switch to the F-35C CV (Carrier Variant) and the third LRIP aircraft was switched to that model, and dubbed CK-1. Though now it looks like the UK may be switching back to the F-35B. That all aside, this is the first flight of an F-35 produced for an international partner.
