741st Missile Squadron The three missile operations squadrons of the 91st Operations Group -- the 740th, 741st and 742nd Missile Squadrons -- include missile crewmembers, alert facility chefs and facility managers. These squadrons vigilantly maintain the missile force around-the-clock. Each squadron controls five missile alert facilities. Missile squadrons are divided into missile operations flights and an operation support flight. The missile operations flights are comprised of officer crewmembers who, when on alert, are responsible for day-to-day operations, maintenance and security of the missiles within their control and are prepared to launch their missiles at all times. Facility managers are responsible for and ensure the readiness of the missile alert facilities. The alert facility chefs are responsible for providing meals to missile alert facility personnel.
