A new hint of the GrowlingShornet struggles with OBOGS:
06 Apr 2017
"...Hypoxia has plagued the Navy’s T-45s and larger fleet of F/A-18 fleet for years now, but the issue has recently received more attention on Capitol Hill. During a 28 March House Armed Services Committee hearing, members of Congress expressed concern over dangerous crew cabin pressure in the older Super Hornets and possible oxygen contamination in the newer F/A-18 variants. The F/A-18A through D models saw a 90% increase in physiological episodes (PEs) over the last fiscal year, while the E and F models saw an 11% increase in the same period. Meanwhile, the EA-18G doubled its number of PEs during that same time."
