Why navies still matter in the age of drones

ASPI Strategist  |  Sean Andrews

Maritime drones are disrupting modern naval operations in the Black Sea and the Strait of Hormuz, yet they remain incapable of achieving decisive sea control or replacing traditional navies. While cheap, expendable drones can damage billion-dollar warships and harass trade routes, they cannot secure shipping lanes, project sovereignty, or uphold maritime order.

Historically, technological shocks like mines, torpedoes, and aircraft triggered similar predictions of battleship obsolescence, yet fleets successfully adapted to preserve their strategic utility. Today, the stark cost asymmetry and threat of saturation swarms force modern surface combatants to operate under compressed decision cycles and persistent surveillance. To survive, navies must shift conceptually by building industrial depth, expanding magazine capacities, and generating localized windows of superiority. Australia's future maritime edge in the Indo-Pacific depends on constructing a resilient, dispersed force that integrates both crewed platforms and uncrewed systems to sustain long-term strategic outcomes.

Comment
New Delhi must accelerate its domestic naval modernisation. Asymmetric maritime threats are rising rapidly in the Indian Ocean. Large surface combatants remain essential for regional sea control. The Indian Navy must integrate uncrewed systems into its traditional fleet structure.
