Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely heroes of DARPA's Persistent Aquatic Living Sensors (PALS) program. Five teams of researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters. This new, bio-centric PALS technology will augment the Department of Defense's existing, hardware-based maritime monitoring systems and greatly extend the range, sensitivity, and lifetime of the military's undersea surveillance capabilities.
DARPA first announced the PALS program in February 2018 with the goal of incorporating biology into new solutions for monitoring adversary movements across the seemingly endless spaces of the world's oceans and seas. Ubiquitous, self-replicating, self-sustaining sea life is adaptable and highly responsive to its environment, whereas maritime hardware is resource intensive, costly to deploy, and relatively limited in its sensing modalities. According to PALS program manager Lori Adornato, “Tapping into the exquisite sensing capabilities of marine organisms could yield a discreet, persistent, and highly scalable solution to maintaining awareness in the challenging underwater environment.”
The DARPA-funded PALS teams must develop or apply technologies to record stimulus responses from observed organisms, and develop combined hardware and software systems that interpret those responses, screen out false positives, and transmit analyzed results to remote end users. The teams' solutions will incorporate technologies such as hydrophones, sonar, cameras, and magnetic, acoustic, and kinetic sensors.
DARPA is also funding the Naval Undersea Warfare Center, Division Newport, under principal investigator Lauren Freeman, to develop a seafloor system that uses a hydrophone array and acoustic vector sensor to continuously monitor ambient biological sound in a reef environment for anomalies. The system will analyze changes in the acoustic signals radiated by the natural predator-avoidance response of coral reef ecosystem biota, which could offer an indirect mechanism to detect and classify underwater vehicles in near-real time.
DARPA conceived of PALS as a four-year research program with the expectation that researchers will be able to publish results for review by the broader scientific community. However, if DARPA identifies any of the data, results, or technical specifications as controlled unclassified information, DARPA will require the PALS researchers to protect them to prevent proliferation outside of official channels.

By: Daniel Cebul WASHINGTON — Mutlidomain operations are set to become standard for the U.S. armed services in the coming years, but technical, doctrinal and organizational hurdles remain. One impediment to multidomain operations involves issues in linking the service's disparate communication and information networks to share targeting data and communications. Rebecca Grant, a national security analyst with IRIS Independent Research, identified her “No. 1 problem" as “the communications architecture.” This stuff is not there yet," she said Wednesday at the Defense News Conference. "I'm less worried about the platforms, we've got some magnificent platforms. We've got to have that communication architecture. All the ability to do that is there, whether that's secure waveforms or the [radio frequency] links, but we have to take the plunge now, immediately, to go out and experiment with this next year.” The need for an integrated communications network was echoed by L3 Technologies' vice president of communications technology. “You need a network that can take all the networks we have right now, a systems-of-systems-level approach, that can tie these disparate networks together because you don't want to get rid of that install base because its too expensive to replace,” Keith Gentile said. Another challenge involves changing the services' doctrinal approaches to operations, especially as each branch becomes more dependent on one another. Gentile said that if the U.S. plans to quickly respond to enemy developments, doctrine surrounding operations in the domains must change. “There's a role mission and function issue that needs to be addressed when you talk about cross-domain or multidomain capabilities because each of the services operates in different domains," he said. "You got to go ahead and get away from the parochial pieces of service stovepipes, mission roles and functions — and realize you are talking about cross-domain capabilities.” Jaret Riddick, the director of the Vehicle Technology Directorate at the Army Research Laboratory, cited the service's recently stood-up Futures Command as one example of change within the services. “I would not downplay the steps the Army is making in standing up Futures Command. To take a four-star command and make the type of reorganization that has not happened since the early 1970s — I would not call that incremental,” he said. https://www.defensenews.com/smr/defense-news-conference/2018/09/05/whats-standing-in-the-way-of-multidomain-operations
