Israel Has 2Nd Thoughts about V-22 Acquisition


V-22s Range Advantage has a Cost
Israel seemed poised to purchase the tilt-rotor V-22 Osprey, and now they have put this on hold.

I am not particularly surprised.

The V-22 is a maintenance hog, and cost a fair amount to operate.

While the Osprey is about 100 kts faster, has a longer range, it can only carry about 1/3 of the payload, even though it has 2/3 of the installed power.

Additionally, unlike a conventional helicopter, the V-22 does not have a meaningful auto-rotation capability, and its performance with external loads is pathetic.

Israel simply does not have the need for the additional capabilities offered by the tilt-rotor:
The Israeli air force has frozen its evaluation of the Bell Boeing V-22 Osprey, with a senior defence source indicating that the tiltrotor is unable to perform some missions currently conducted using its Sikorsky CH-53 transport helicopters.

In January 2014, the US Department of Defense notified Congress about its intention to sell six V-22s to Israel. This followed an evaluation conducted by air force personnel, which led to the service seeking a rapid acquisition to support special operations. The proposed purchase met with opposition from elsewhere within Israel's defence ministry, however.

Other potential candidates to replace the Israeli air force's aged CH-53s by around 2025 include Sikorsky's new CH-53K and the Boeing CH-47 Chinook.
Simply put, the IDF does not have the requirements, such as amphibious landings from extreme distance, that have driven the V-22, and as such, it does not make sense.
