Battlefield 6 Season 4 adds naval warfare, new Tsuru Reef map and Wake Island

Electronic Arts and DICE announced that Battlefield 6 Season 4 will launch on 21 July 2026. The free update introduces a full naval warfare mode, featuring the largest map to date – Tsuru Reef – with dynamic waves, islands and coastal combat. Classic map Wake Island returns later in the season. New naval vehicles include the RCB‑90 patrol boat and the 7.7 m NSW RHIB, while four new weapons such as the Interdictor sniper rifle are added. The trailer also teases a two‑seat jet return and a possible Top Gun collaboration, showing an F‑14 Tomcat. Additional features include a new Ranked Battle Royale season, custom lobbies and spectator mode. The update is positioned as a major expansion to the game’s land‑air‑sea combat sandbox.
