What is Charlotte Keene's military role in Silo season 3?

In Silo season 3, Charlotte Keene’s military role is naval aviator.

Charlotte is introduced in the Before Times storyline as a United States Navy aviator. Her role connects the season’s political thriller material to the catastrophe that eventually forces humanity underground. She is also the sister of Daniel Keene, a congressman whose investigation becomes central to the season’s origin story.

Charlotte’s military background is more specific than simply calling her a pilot. She flies from a naval carrier as part of a mission involving Iran, placing her directly inside the geopolitical crisis that precedes the Silo project. The mission takes a strange turn when the aircraft encounter a destructive airborne substance.

Viewers may confuse her with an Air Force pilot or another military specialist because the series presents her through fighter-aviation scenes. The canonical description, however, is naval aviator: Charlotte is a Navy flyer, not a Marine sniper, Air Force general, or Army medic.
