Hello
The CV-22FC was the “flying Crane “version of the V-22.
It feature a redesigned rear fuselage (or the almost lack of it) and more powerful engines.
This variant was used by several civilian companies and used in a number of heavy lifting tasks (including cargo, firefighting, etc.).
The CV-22FC had the ability to use standardized pods that could be configured to many different missions. The pods could be fitted to any aircraft thanks to the standardized connections and dimensions, allowing for great versatility.
Below we see an example of a medical evacuation pod (US Army) and a command post (US Marines).
There were also specialized pods for electronic warfare, reconnaissance, psychological warfare, etc.
