Control of the maritime domain underpins global trade, power projection, and strategic deterrence. As oceans become more contested and transparent, navies must balance traditional fleet roles with new challenges in undersea warfare, missile defense, and distributed operations.
This sub-magazine explores how maritime forces secure sea control, deny access, and project power across regions.
IDST Intelligence Briefings
Our maritime briefings place ships, submarines, and naval aviation within broader fleet architectures, explaining how sensors, weapons, and command systems enable—or limit—naval effectiveness.
Why This Magazine Exists
Naval power is not defined by ship counts alone. It depends on fleet integration, sustainment, basing, and the ability to operate under missile and submarine threats.
This sub-magazine exists to analyze maritime power as a system, not a collection of platforms.
What We Track
This magazine tracks developments across the full Naval and Maritime spectrum, including:
- Surface combatants and fleet composition
- Submarine warfare and undersea dominance
- Naval aviation and carrier strike integration
- Anti-ship, missile defense, and area denial systems
- Maritime surveillance and domain awareness
- Logistics, shipbuilding, and naval industrial bases
