Royal Navy’s HMS Dauntless Spotted Carrying Possible New Counter-Drone System

The photograph is unremarkable at first glance: a Type 45 destroyer alongside, its familiar silhouette interrupted by two new container structures bracketing the Phalanx close-in weapon system mounts. But the placement is the story. HMS Dauntless already carries one of the most capable naval air-defense radars afloat in the SAMPSON and S1850M combination, and its Aster missiles are among the most expensive surface-to-air interceptors in service. What the ship has lacked is a cheap, high-capacity layer for the small, slow, numerous threats that have dominated recent naval engagements. The containers suggest the Royal Navy is experimenting with exactly that layer, and the choice of a Type 45 as the testbed tells us the service is thinking about how to protect its most valuable hulls without emptying the magazine on targets that cost less than the missile used to kill them.

The mechanics matter. Phalanx is a gun-based close-in weapon system with a limited engagement envelope and a finite ammunition supply. It was designed for the leaker, the missile that got past the area-defense screen. It was not designed to be the primary defense against a coordinated drone attack arriving in waves from multiple azimuths. Vertically launched interceptors, by contrast, offer 360-degree coverage, rapid reload from a container magazine, and the prospect of a much lower cost per shot if the effector is designed for the counter-UAS mission rather than the anti-ship missile mission. The container form factor is significant because it implies a system that can be bolted onto ships that were never designed for it, a modular approach that avoids the cost and schedule risk of a major combat system upgrade. That is the same logic behind the proliferation of containerized weapons across navies: decouple the effector from the platform, and you can field capability faster and cheaper.
