Okay, So The F-35 has Numbers By 2020

Below is a build progression of the F-35. Of course, numbered are partner sales and foreign delivery beyond what the US Takes from Lockheed's F-35 production lines.

The year 2019 projects 130+ F-35 units to be delivered to all its customers by the end of this year.
The United States will receive a bulk of 2019 deliveries reported below.
 

2019                        130 F-35's completed

About 60's F-35 have reached foreign military operations where 2019 will see a boost in delivered F-35 to other countries around the world. 

Having 358 F-35 delivered through 2018 suggests about 297 F-35's are with the US for testing and for the operational force. 

The summary for the F-35 looks impressive as the US military tries to achieve having over 1,700 of the F-35's A, B, and C in its military inventory. If the pacing remains the same for delivering around 150 F-35's every cycle. Expect a 20% to 80% for a foreign to US delivery split over the next years.

Charting out a rate of 160 units a year will give it a ten-year build cycle to reach over 2,000 F-35 units.

The remaining world's military production pace falls behind the Lockheed pace. The Russian model 57 and Chinese models 21, 31, or even its 10 will be a paltry number made compared with the F-35 production fleet. China makes up a lot of ground with its missile innovations.
