This flexibility makes submarines a valuable asset in a wide range of military operations, from defending sea lanes to conducting long-range strikes against enemy targets. In addition to their offensive capabilities, submarines also play a critical role in intelligence gathering and surveillance. Submarines can be used to monitor enemy activities, gather information on enemy forces, and track the movement of enemy vessels. This intelligence can be used to support military operations, inform decision-making, and enhance situational awareness on the battlefield. Submarines are also highly effective in denying the enemy access to key areas of the ocean.
