The U.S. Air Force Chemical, Biological, Radiological and Nuclear Defense Systems Branch fielded new respirator masks to the 563rd Operational Support Squadron (OSS) and 755th OSS, on March 7, 2024.

The new mask, known as the Joint Service Aircrew Mask Strategic Aircraft or M69, replaced the legacy MBU-19/P Aircrew Eye and Respiratory Protection equipment, which launched in the early 1990s.

Davis-Monthan was provided the new chemical defense masks for aircrew members to wear while flying during chemical attacks.

“The M69 is a new material solution,” said Kevin O’Neal, Air Combat Command aircrew flight equipment operations specialist. “This week, we are conducting new equipment training as part of the total package fielding.”
