The U.S. Navy Is Trying to Build What Could be the Ultimate Weapon: A Swam 'Ghost' Fleet
The Navy and DoD are engineering high-tech, removable Unmanned Surface Vehicle “kits” designed to change amphibious warfare by delivering combat-relevant supplies, firing weapons, swarming enemies, refueling ships, searching for enemy mines and submarines and dispersing attacking forces to minimize risk from enemy fire.
The Navy is working hard to advance an emerging “ghost fleet” concept wherein multiple surface, air and undersea drones operate in a synchronized fashion to conduct a wide-range of combat missions without placing sailors and marines at risk.
“We want to have multiple systems teaming and working together, surface, air and undersea,” Capt. Jon Rucker, program manager, Unmanned Maritime Systems, PEO LCS, said at the recent Surface Navy Association.
Rucker explained that the Pentagon and Navy are advancing this drone-fleet concept help to search and destroy mines, swarm and attack enemies, deliver supplies and conduct intelligence, reconnaissance and surveillance missions, among other things.
Swarms of small aerial drones, engineered with advanced computer algorithms, could coordinate with surface and undersea vehicles as part of an integrated mission, he explained.
As communications and networking technologies continue to evolve rapidly, drones will increasingly be able to function in a cross-domain capacity, meaning across air, sea, land and undersea operations.
Aerial swarms, for instance, could detect an enemy surface vessel and relay information to unmanned surface vessels or undersea drones to investigate or even attack. All of this could operate in a combat circumstance while needing little or no human intervention.
Rucker explained that the Navy, and its Office of Naval Research (ONR), has been working closely with the Pentagon’s once-secret Strategic Capabilities Office, or SCO, in an effort to fast-track this kind of technology into operational service.
The Strategic Capabilities Office is a special DoD-level effort to harness, leverage and integrate near-term emerging technology for faster delivery to combatant commanders at war.
Much of this involves merging new platforms, weapons and technologies with existing systems in a manner that both improves capability while circumventing a lengthy and often bureaucratic formal acquisition process, Dr. William Roper, SCO Director, told a small group of reporters last year.
The Office of Naval Research (ONR) has demonstrated technological advances in autonomy with groups of swarming Unmanned Surface Vessels (USV) designed to detect enemy ships, perform surveillance missions or even launch attacks, service officials said.
Algorithms governing autonomous maritime navigation have progressed to the point where USVs can more effectively “perceive” and respond to their surrounding environment while in transit, Robert Brizzolara, program manager, Sea Platforms and Weapons, ONR, recently told reporters.
During a recent “swarm” boat demonstration in the lower Chesapeake Bay, ONR-developed boats achieved a key milestone in the area of autonomous control.
“Unlike purely remote controlled boats, these boats are able to perceive their environment and plan their routes without human intervention. The role of the human is supervisory control,” Brizzolara said.
A human at a control station, using a low bandwidth connection, can perform command and control functions without needing to actually drive the vessels.
The demonstration used four USVs, working in tandem to perform a range of potential maritime combat operations. All four of the boats were able to see and sense a common picture for route planning, hazard avoidance and collision prevention, developers said.
“We are using a first-of-its-kind sophisticated perception engine which senses the presence of other vessels using a combination of sensors, radar, cameras and processing algorithms,” Brizzolara explained.
The ONR demonstration used 7-to-11 meter boats already in the Navy inventory as manned boats, and configured them with an autonomy “kit” enabling a range of unmanned mission possibilities.
The kits, called Control Architecture for Robotic Agent Command and Sensing, or CARACaS, are engineered to provide USVs with an ability to handle dynamic operational situations; this can include the execution of search patterns, harbor defenses, surveillance or even swarm boat attacks. Other possibilities among a wide range of uses include using autonomous USVs for supply and weapons transport, countermine operations, electronic warfare and amphibious operations.
The USVs are programmed with sensors linked to an established database of known threats such as enemy boats; they are also linked to one another with an ability to detect, track and trail “unknown” boats, Brizzolara said.
ONR is working closely with the Pentagon’s once-secret Strategic Capabilities Office, or SCO, in an effort to fast-track this technology into operational service.
The Strategic Capabilities Office is a special DoD-level effort to harness, leverage and integrate near-term emerging technology for faster delivery to combatant commanders at war. Much of this involves merging new platforms, weapons and technologies with existing systems in a manner that both improves capability while circumventing a lengthy and often bureaucratic formal acquisition process, Dr. William Roper, SCO Director, told a small group of reporters.
A key advantage of using remotely-controlled drone ships is that, quite naturally, they can save sailors and marines from being exposed to enemy fire during an attack operation. In fact, Roper maintained that USV autonomy brings the potential of substantially advancing amphibious warfare tactics.
