The first F-35 delivery of 2017 was a milestone, the 200th operational jet, which is now the second delivered for the Japan Air Self Defense Force. The aircraft touched down at Luke AFB, Ariz., on Tuesday, according to a Lockheed Martin release. The jet brings the total number of F-35s at Luke, a training base for US and international pilots to 46. Eventually the base will host 144 strike fighters in six F-35 fighter squadrons.

The delivery came as the Pentagon’s weapons tester said the program’s initial operational test and evaluation will further slip a minimum of 16 months.
