  All aboard the Sea Train!

  Imagine the following scenario. Four medium-sized U.S. Navy vessels depart from a port along the United States' coast. There's no crew aboard any of them. About 15 nautical miles off the coast, the four vessels rendezvous, autonomously arranging themselves in a line. Using custom mechanisms, they attach to each other to form a train, except they're in the water and there's no railroad to guide them. In this configuration the vessels travel 6,500 nautical miles across the open ocean to Southeast Asia. But as they approach their destination, they disconnect, splitting up as each unmanned ship goes its own way to conduct independent operations, such as collecting data with a variety of onboard sensors. Once those operations are complete, the four reunite, form a train and make the return journey home. This is the Sea Train, and it may not be as far-fetched as it sounds. The Defense Advanced Research Projects Agency is investing in several technologies to make it a reality. “The goal of the Sea Train program is to be able to develop and demonstrate long-range deployment capabilities for a distributed fleet of medium-sized tactical unmanned vessels,” said Andrew Nuss, DARPA's program manager for Sea Train. “So we're really focusing on ways to enable extended transoceanic transit and long-range naval operations, and the way that we're looking to do that is by taking advantage of some of the efficiencies that we can gain in a system of connected vessels — that's where the name ‘Sea Train' comes from.” According to DARPA, the current security environment has incentivized the Navy and the Marine Corps to move from a small number of exquisite, large manned platforms to a more distributed fleet structure comprised of smaller vessels, including unmanned platforms that can conduct surveillance and engage in electronic warfare and offensive operations. While these unmanned vessels are smaller and more agile than their large, manned companions, they are limited by the increased wave-making resistance that plagues smaller vessels. And due to their size, they simply can't carry enough fuel to make the long-range journeys envisioned by DARPA without refueling. By connecting the vessels — physically or in a formation — the agency hopes the Sea Train can reduce that wave resistance and enable long-range missions. In February, the agency released a broad agency announcement to find possible vendors. Citing agency practice, Nuss declined to share how many proposals were submitted, although he did say there was significant interest in the announcement. The agency completed its review of any submissions and expects to issue contracts by the end of the fiscal year. Sea Train is expected to consist of two 18-month periods, where contractors will work to develop and test technologies that could enable the Sea Train concept. The program will culminate with model testing in scaled ocean conditions. If successful, DARPA hopes to see the technologies adopted by the Navy for its unmanned platforms. “What we're looking to do is be able to reduce the risk in this unique deployment approach,” Ness said. “And then be able to just deliver that set of solutions to the Navy in the future, to be able to demonstrate to them that there is, potentially, a new way to deploy these vessels, to be able to provide far more operational range without the risk of relying on actual refueling or in-port refueling.” And while DARPA's effort is focused on medium-sized unmanned vessels — anywhere from 12 to 50 meters in length — the lessons learned could be applied to larger or smaller vessels, manned or unmanned. https://www.c4isrnet.com/unmanned/2020/06/01/all-aboard-the-sea-train/

  US Army triggers start of possible ground mobility vehicle competition after long delay

  By: Jen Judson WASHINGTON — The Army seemed geared toward holding a rapid competition to buy a Ground Mobility Vehicle in 2016, but the plan was delayed without much explanation in favor of buying an interim vehicle already in use by special operations forces. Buying the GMV was a top priority following the fall 2015 release of the Army's Combat Vehicle Modernization Strategy, which called for such a vehicle in future and current operations. After a competition never materialized, however, rumors began to swirl that the Army may decide to buy more of the U.S. Special Operations Command's GMV — General Dynamics Ordnance and Tactical Systems' Flyer 72 — even after the service had spent several years prior testing a wide variety of commercial off-the-shelf options. But Congress spurred the effort in its fiscal 2018 defense policy bill, mandating the Army hold a competition and move forward with a program. The Program Executive Office Combat Support and Combat Service Support's product lead for the GMV has quietly stated on its website that the Army plans to pursue a competition for the GMV — calling it an Infantry Squad Vehicle — as a formal program of record. The office states that it is projected to enter into a production contract in fiscal 2020 to procure 2,000 vehicles, roughly a year later than originally planned. The Army took a big step forward on Sept. 24, releasing a market survey to industry, via the Federal Business Opportunities website, soliciting offerings for an Infantry Squad Vehicle. The notice states the service is looking for a vehicle that provides mobility for a nine-soldier infantry squad as well as its associated equipment to “move around the close battle area.” The vehicle should be lightweight, highly mobile and transportable “by all means” to include CH-47 Chinook cargo helicopters, UH-60 Black Hawk utility helicopters and by Low Velocity Air Drop. Responses to the solicitation are due on Oct. 26. While the Army has already bought quantities of the SOCOM vehicle for five airborne infantry brigade combat teams, other companies have continued to wait in the wings for the possibility to compete. And the pool of readily available ultralight vehicles is deep. In addition to GD's Flyer, these vehicles all participated in vehicle demonstrations at Fort Bragg, North Carolina, in 2014: Boeing-MSI Defense's Phantom Badger. Polaris Defense's air-transportable off-road combat vehicle DAGOR. Hendrick Dynamics' Commando Jeep. Vyper Adamas' Viper. Lockheed Martin's High Versatility Tactical Vehicle, which is a version of the British Army's HMT-400 Jackal. The Army launched its new-start GMV program in 2017 as planned, based off the service's new combat vehicle modernization strategy released in 2016, which called for the capability. The Army planned to reach a full-rate production decision on a vehicle by the end of FY19. But then it decided to split GMV procurement into two phases in the FY18 budget request and, in the first phase, planned to exclusively buy 295 of GD's Flyers through a previously awarded contract with U.S. Special Operations Command. The second phase would open up into a competition to build 1,700 more GMVs. Procuring the GMV vehicles from SOCOM raised the unit cost of the vehicle higher than the unit cost of ones that would have been procured through competition, according to FY18 budget documents. https://www.defensenews.com/digital-show-dailies/ausa/2018/10/09/us-army-triggers-start-of-possible-ground-mobility-vehicle-competition-after-long-delay
