Yeah! The Plane Works as Designed!

The F-35 is engineered with an ability to dogfight and engage in air-to-air combat, yet it was also designed with an array of next-generation sensors designed to see, detect and destroy enemy targets from much farther ranges than existing fighter jets can. The concept is to find, see and eliminate enemy air threats well before the F-35 itself can be detected.
