What is the name of the newest aircraft in the US Navy?

The correct answer is the F-35 Lightning II, which is the newest aircraft in the US Navy. The F-35 is a multirole stealth fighter designed to perform ground attack, aerial reconnaissance, and air defense missions. Its advanced technology, including stealth capabilities, sophisticated avionics, and sensor fusion, represents a significant leap in combat aircraft design and performance compared to older models.

The F/A-18 Super Hornet, while an effective and versatile aircraft, has been in service since the late 1990s and does not represent the newest addition to the fleet. The EA-18G Growler is an electronic warfare variant of the F/A-18 that has also been in service for several years. The V-22 Osprey is a tilt-rotor aircraft primarily used for transport and has been operational since the early 2000s. Thus, when considering the latest advancements and introductions in naval aviation, the F-35 Lightning II clearly stands out as the most recent implementation in the US Navy's aviation arsenal.
