In what year was the name of the career field changed from "Air Police" to "Security Police"?

The name of the career field changed from "Air Police" to "Security Police" in 1966. This change reflected a broader evolution within the military and law enforcement communities towards a more comprehensive focus on security forces rather than just policing functions. The term "Security Police" encompassed a wider range of responsibilities, including law enforcement, installation security, airbase defense, and support for combat operations.

By adopting this new terminology, the military aimed to align the role of its security personnel with the growing importance of security and defense strategies during that period, particularly as threats evolved during the Cold War. This shift signified a commitment to adapting to modern threats and ensuring that personnel were prepared for diverse challenges beyond traditional policing.
