The Defense Advanced Research Projects Agency has awarded contracts for its Sea Train program, which seeks to enable autonomous vessels to perform long-range transit operations.
In September, Applied Physical Sciences Corp., Gibbs & Cox Maritime Solutions and Mar Technologies were chosen for the program, which will include two 18-month phases.
The contract awards' total potential values were $31.2 million, $30.4 million and $28.5 million, respectively. Through the effort, DARPA wants “to provide some operational flexibility for medium-sized unmanned surface vessels,” said Andrew Nuss, a program manager within the agency's tactical technology office. Each company is “developing a unique approach to be able to address the goals of the Sea Train program.”
Unmanned surface vessels are generally limited in operational range, typically 3,500 to 4,000 nautical miles, he said in an interview. However, DARPA hopes to extend that to about 14,000 nautical miles under the Sea Train program.
Usually unmanned surface vessels must undergo multiple refuelings to go farther distances, he noted.
“It's sort of a vicious cycle at that point, where you're constantly chasing efficiencies and whatnot,” he said. However, a Sea Train platform — which is expected to be 40 meters long and carry a 35-ton payload — could give an operational commander “the flexibility to deploy these highly capable medium-sized unmanned surface vessels from many different locations without having to rely on ... refueling operations.”
DARPA plans to extend the range of USVs more efficiently by creating a “train” in which four autonomous vessels are physically connected until they reach their destination.
The platforms would then detach, conduct their individual operations and then reconnect before returning to their starting point, Nuss said. Unmanned boats must overcome resistance and friction from waves as they move, but attaching the platforms may help increase their efficiency and allow them to travel longer distances, he said.
“By physically connecting multiple vessels together, and extending the length of that interconnected system, we could move — in our case — four vessels with ... approximately the same efficiency of a single vessel,” Nuss said.
The medium-sized platforms were picked for proof of concept, but the idea could be applied to smaller vessels or manned systems as well, he noted.

A $550 million funding increase will allow the agency to launch a batch of 28 missile warning satellites in early 2025 ' at least a year earlier than previously planned, according to a senior defense official.

By: Mark Pomerleau The new head of the Marine Corps' nascent information directorate is focusing on three priorities: network modernization, putting new information-related units to work and gaining asymmetric advantage. The Marine Corps reorganized its leadership in 2017 to create a new three-star position, the deputy commandant for information, that would oversee all aspects of information war to include cyber, electronic warfare, signals intelligence and information operations. Over the summer, Lt. Gen. Lori Reynolds became the second officer to hold this new position. William Williford, executive director of Marine Corps Systems Command, provided an outline of various efforts to modernize the network during the Charleston Defense Contractors Association Defense Summit on Dec. 5. The initiative includes: broader adoption of Windows 10, creating a cloud cross functional team, starting a network cross functional team, fielding Tampa microwave terminals, protecting spectrum used for the F-35 and running a pilot program to help ensure GPS signals aren't jammed. Kenneth Bible, deputy director of the C4 directorate and deputy chief information officer, said during the same conference that the Marines still have IT solutions that date back to the Navy-Marine Corps Intranet days that have to be modernized The Marine Corps needs to divest of some of its legacy systems and modernize them, he said. He added that Marines are finding there are systems needed to get the network “up to snuff to go support that.” Additionally, he said, systems need to be capable of supporting the automation needed in order to make the network more effective. Regarding the second line of effort, the deputy commandant is focused on using the new Marine Expeditionary Force Information Groups, or MIGs. These teams will work on all information related capabilities, providing commanders a clearinghouse of options including cyber, intelligence, electronic warfare and information operations. Bible said Marine Corps leaders are working hard to figure out how the groups can directly help commanders. Third, Bible said the Marines want to gauge whether they can create an asymmetric advantage. “How do we shape the conflict before we end up in a conflict,” Bible said. “A lot of this is going to merge in the information environment.” Some of the efforts related to providing an asymmetric advantage will involve Navy partners, Bible said. He discussed the need to for Marines to fight to get to the fight. “We're probably not going to have enough organic aviation assets to get all the Marines to all the different places that an advanced expeditionary base operations concept [and] very distributed operations” demands," he said. That will require partnering with the Navy in some regards. https://www.c4isrnet.com/it-networks/2018/12/07/3-priorities-for-the-marines-information-directorate
