Red Storm: Baltic Approaches is the first expansion for GMTs Red Storm game of operational level air combat between NATO and the Warsaw Pact. Red Storm: Baltic Approaches adds the air forces of three new countries (Denmark, Sweden, and Poland) along with additional units for nations represented in Red Storm, including US Marine Corps aircraft. The game will also add naval units, anti-ship missiles, maritime weather, and rules covering other facets of air combat in the predominantly maritime domain of the western Baltic.

Scenarios featuring mission types from Red Storm (close air support, interdiction, air defense suppression, and deep strike) will be joined by new types focused on raids against enemy ships, amphibious operation support, airborne drops, and aerial mining. Solo scenarios, using the Bot system introduced in Red Storm, will also be included.
