The official gameplay trailer for Battlefield 6 Season 4's naval systems has been released, offering a first look at the Naval Warfare content launching on 21 July 2026. The footage highlights large-scale sea-based combat across new maps, including Tsuru Reef, described as the game’s biggest battlefield yet, where islands, dynamic waves, boats, jets, helicopters and ground vehicles converge. Players will be able to operate the RCB-90 Patrol Boat and 7.7m NSW RHIB, access four new weapons including a sniper rifle, and compete in a new Ranked Battle Royale season with additional rewards. Wake Island is also scheduled to return later in the season.
