Air Force requests $87M reprogramming for 'enhanced' T-6 OBOGS

The Air Force wants to shift $87 million to buy and install Enhanced On-Board Oxygen Generating Systems on its 445 T-6 trainers.

The request was included in an April 17 reprogramming document obtained by Inside Defense and comes about a year after the Air Force paused T-6 flying following a sudden increase in the number of pilots reporting hypoxia-like conditions.

The new system will feature an OBOGS concentrator, engine bleed air shutoff valve, mechanisms to remove water and moisture from the upstream bleed air system, and an automated backup oxygen system. It will also include a maintenance system and sensors that measure pilot intake levels.
