I believe the comments on survivability relate to the increased risk as a result of removing the
fueldraulic valves and PAO shut-off valves and dry bay fire suppression as a weight saving measure. All of which they want restored but without a weight increase.
That's in addition to the
OBOGS system not being able to maintain fuel tank inerting through critical portions of a flight profile. Resulting not only in the combat risk, but the F-35 being currently unable to fly in forecast lightning conditions...
But apart from that, it's OK.........
