ARLINGTON, Va. – U.S. military researchers are working with industry to develop real-time command-and-control communications networks that function above, on, and under the ocean using the latest in undersea communications and unmanned underwater vehicles (UUVs).

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., issued a broad agency announcement on Friday (HR001119S0067) for the Timely Information for Maritime Engagements (TIMEly) project.

TIMEly seeks to develop a heterogeneous maritime communications architecture, and the demonstrate a prototype during sample missions at sea. The project emphasizes undersea communications, as well as communications among manned and unmanned submarines, surface vessels, aircraft, and satellites.

The goal is to create rapidly reconfigurable military forces under, on, and over the ocean that are fast, unpredictable, flexible and adaptable -- more like the pieces in a mosaic piece of art, rather than a collection of rigidly designed pieces of a puzzle.

U.S. military officials are trying to create rapidly reconfigurable military forces that move quickly, adapt to changing circumstances, and continue to function efficiently even though some segments may disappear or be called away to higher-priority missions.

The TIMEly project takes this concept of "mosaic warfare" into consideration, but emphasizes underwater assets like manned submarines and UUVs to provide options on the fly for carrying out different missions.

TIMEly networks must be able to work together with established military networks to be effective, DARPA researchers say. The undersea domain imposes well-known limits on communications and on the ability to transfer the right information to warfighters.

The project will focus on network protocols, quality of service, and information exchange, with the understanding that the undersea environment limits the range, capacity, latency, and security, of network links.

TIMEly envisions dynamically reconfigurable responsive architectures that will capitalize on advances in undersea communications, and autonomous ocean systems.

This four-year project has three phases: A 15-month first phase that focuses on design and component-level testing; a 15-month second phase that focuses on architecture builds and in-water demonstrations; and a 15-month third phase that focuses on a multi-domain operational demonstration with prototype hardware.

Proposers must submit a statement of work that covers all three phases, each independently priced. DARPA officials say they will spend as much as $45 million on the project, which will involve several contract awards.
