African countries are increasing investments in submarines to strengthen naval capabilities amid rising maritime security challenges. Submarines support intelligence gathering, deterrence, and operations in contested waters.
Countries with extensive marine borders view them as essential for protecting territorial waters and maintaining security. As Africa expands its role in global trade and geopolitics, maritime defence remains a priority. Submarines also support joint military exercises, peacekeeping, and maritime security efforts.
Their advanced technology aids in countering threats, including terrorism and environmental risks. Additionally, submarines contribute to disaster relief and search-and-rescue operations, reflecting their growing role in regional and global security.
