How many jump jets does the USMC have?

As of my last update in October 2023, the United States Marine Corps (USMC) operates the MV-22 Osprey tiltrotor aircraft, which can be considered a type of jump jet due to its vertical takeoff and landing capabilities. The exact number of MV-22s can vary, but the USMC has around 400 Ospreys in service. Additionally, they have the F-35B Lightning II, a stealth multirole fighter with vertical takeoff capability, with plans to acquire approximately 400 units. Overall, the total number of jump jet-type aircraft in the USMC is around 800 when considering both platforms.
