Would it be a good idea to have a Baltic bastion similar to the Atlantic bastion?
Short answerYes. It would focus on local convoy defense against air, drone, and missile attack instead of Atlantic-style ASW.
NotesAn Atlantic bastion protects ocean movement against submarines. A Baltic version would keep local sea lanes open under air, drone, and missile attack so convoys could continue delivering supplies. Escorts would provide large numbers of defensive shots against saturation attacks, while land-based fighters and heavier systems supplied additional cover. Type 31-derived ships carrying CAMM, as discussed for Poland, and Swedish frigate proposals illustrate the local air-defence role. The required balance of weapons follows the threats to the convoy route.
