A former U.S. Northern Command leader warned on Thursday about the “incredible gaps” facing U.S. homeland defense, specifically referencing air defense below space.

Retired Gen. Glen VanHerck, who served as NORTHCOM’s commander from 2020 to 2024, said during a Mitchell Aerospace event that he’s “not satisfied at all” with the current balance of the military’s posture, arguing that the “expectations in policy exceed the capacity for the forces that we have.”
