How can spy planes help in the defence of Ukraine?

Analysts stationed on the plane and at the base assess the information gathered and turn it into "intelligence" about Russian movements.

The West has powerful "ears" monitoring Russian military chatter through the use of spy planes, which conduct tracking missions with amazing capabilities.

These advanced planes and drones are equipped with devices that can allow them to collect signals sent from Russian bases and intercept communications.

Real-time intelligence can be provided so that analysts and linguists can exploit it to track an enemy.
