Naval aviators eat with the ship's company

Do naval pilots receive a different diet from surface personnel of the same rank?

No; they eat the same food, though meal timing can be adjusted around long missions.

Giving one professional group conspicuously different food would undermine cohesion aboard a single ship. Carrier routines already provide meals around the clock because the vessel operates continuously, and aviators receive flexibility before or after long sorties. Practical limits on eating and drinking before an extended single-seat flight arise from the aircraft's minimal toilet provision, not from a separate naval diet.
