Maryland Fleet Week and Air Show starts tomorrow and ends on October 9 (https://www.visitmaryland.org/things-to-do/fleet-week).
In past years FiRST and the Baltimore City System were pretty active. Marine frequencies were patched to the BC System. Area Commands operated on FiRST Tac Channels. I would assume the Marine Tac Channels on FiRST would also be used. I would also expect operations at Martin State Airport to operate on Baltimore County System but I don't monitor that system much so no idea what talkgroups would be active.
