What is Benson primarily known for within the RAF?

Benson is primarily known as the main operating base for support helicopters within the Royal Air Force (RAF). This base plays a crucial role in the operational deployment and maintenance of various helicopter types that provide support across a wide range of missions, including search and rescue, transportation, and tactical operations. The facilities at Benson are specifically designed to accommodate the needs of these aircraft and their crews, ensuring readiness and efficiency in their deployment.

The other options represent important aspects of the RAF's operations but do not accurately reflect the primary role of Benson. For instance, while air surveillance and strategic transport operations are vital capabilities within the RAF, they are not the main focus of Benson. Similarly, joint military exercises occur at various locations across the UK and are not specific to Benson, which is more dedicated to helicopter operations.
