Science, technology and doctrine combine in the Navy's program for unmanned surface vessels

Other at-sea industries are developing unscrewed vessels, but these efforts won’t provide what military applications require, Small said.

Story Highlights:

  • Capt. Pete Small, program manager for unmanned maritime systems, noted development of these systems is a tri-component effort of Navy, Marine Corps and Coast Guard.

  • He described three basic platforms in varying stages of development testing: small, medium and large. At roughly 40 meters in length, Small said the most diminutive USVs, called Sea Hunter, are destined for operations including mine-detection and sweeping or submarine detection. Small said the Navy envisions 200-meter, medium USVs, known as Seahawk, as distributed sensor platforms operating out ahead of manned ships or groups to extend their view.

Small said the Navy plans its large USVs, for which it has a rough architecture, as direct extensions of the Navy’s lethal surface combatant force. Such a vessel would operate as what he called an adjunct magazine, giving for greater and more affordable distributed forces.

He said the development challenges for USVs fall into five technology areas:

Small emphasized that in call cases, USVs will be remotely commanded and controlled, by crews aboard afloat assets, other ships. That is, USV won’t be autonomous or able to make weapons firing decisions on their own.

Hull, mechanical and electrical systems including propulsion – they all need to operate more reliably than those of manned systems.
Communications circuits for remote command and control – this includes the networks and radios on board to connect to human over watch staff, who would guide the USVs and reprogram them as contingencies arise.
Payloads that are meaningful for wartime missions
Software, in particular the human-machine interface that appears before the operators’ eyes aboard the destroyer they’re working from
Self-awareness of the vessel itself from its sensors, small called these the crown jewels – this characteristic will determine how smart is the vessel is to take in sensory information from radars or sonars, then fusing the inputs and acting on them.
