This mobile comms unit has people talking

By:

The Army has a slew of ongoing efforts to modernize its tactical network, including a focus on a pilot unit that moves quickly through the world and spectrum to tailor critical communications systems support.

The Expeditionary Signal Battalion-Enhanced (ESB-E) supports units that don't have organic comms capabilities. These could include military intelligence battalions, chemical battalions, engineering battalions or air defense artillery branches.

The ESB-E can also augment regular Army units, as a renewed focus on great powers requires all units to be much more mobile and expeditionary. What that means for signal battalions is their gear will have to be easily carried and set up to enable them to maneuver with units in a rapid manner.

“The Army's transitioned to focusing on data environment and near-peer threat. The need for those logistical tails and for the enablers to move rapidly has increased, which is part of the demand signal that has gotten us away from” the Warfighter Information Network-Tactical of the past, Maj. Jeff Forry, S-3 50th Expeditionary Signal Battalion, told C4ISRNET during a demo of Army network modernization efforts at Fort Myer June 18.

Forry said they've provided much more modular and scalable capabilities than the Humvee-mounted, satellite transportable terminal-based capabilities of year's past.

In March 2018, the Army authorized the beginning of the ESB-E pilot, which is intended to create more mobile and agile kits for signal brigades.

As part of the pilot, three companies under the battalion have been outfitted with capabilities from three vendors. This includes basebands — made by DTech, PacStar and Klas — with accompanying Tampa Microwave or L3 satellite terminal dishes of varying diameter depending on the users the unit needs to accommodate.

Overall, the battalion has packages to provide communications for a variety of users.

“When I plan a mission, less than 20 users, I'd start looking at small [packages] ... when we start pulling 20 up to 48 I'm looking at medium, and then after that we'd either use multiple mediums or start looking at the [large] package,” Forry said.

The modularity of the kits mean, in many cases, just adding more users merely involves just sliding a small router into the baseband and utilizing a slightly larger satellite terminal. This is easier than the old WIN-T way of doing things where teams needed to bring full transit cases to add more users and bandwidth.

One user noted that the modularity of the kit allows teams to mix and match based on the requirement. For example, if they only need connectivity to the Pentagon's secret network, as opposed to the unclassified network, they only need to bring those services with them.

During a recent event at Dugway Proving Grounds, members from the signal battalion supported a chemical brigade, which had to get in and out of affected areas very quickly. The team took a small package and was able to get communication up in less than 10 minutes. They were onsite for 20 minutes, packed up and moved to the next site.

The Army is continuing to utilize training events, combat training center rotations and exercises such as Saber Guardian in Europe to evaluate systems within the pilot program and execute operational tests for the gear.

“The different approach we took for this prototype that we're doing is we didn't go set off a dedicated unit to do an operational test,” Col. Greg Coile, project manager for tactical networks at Program Executive Office Command, Control, Communications-Tactical, said. “Their operational test is when they go to Saber Guardian, when they go do the operational support, that is how we're testing and ... we use that user feedback going forward.”

Coile added that this ongoing experimentation also allows units to get more repetitions as opposed to the old way of doing things, where the unit would get the equipment two weeks ahead of an operational test at something like the Network Integration Evaluation. Now units get an entire year with the equipment, which means the value of feedback is much higher, Coile said.

The capabilities for the ESB-E unit will be part of the Army's first delivery of capability in 2021 for its network modernization the service is calling capability set 2021.

Coile said the pilot will run until September, after which the Army will begin to make decisions on down-selecting vendors and outfitting actual units with the kits. The plan is to have every unit have the same equipment, as opposed to three companies currently outfitted with different vendor equipment for the prototype.

A battalion will be complete in 2019, Coile said, and they are funded for three more in 2020. Moreover, they'll buy more in late 2020 to early 2021 and field those three.

In 2021 there is funding for another three units, but the Army leadership will have to make a decision on what units get that.

    General Dynamics To Invest $1 Billion In Production Facilities Upgrades With Focus on Subs

    By: Ben Werner General Dynamics Corp. plans to invest $1 billion in 2019 in upgrading and retooling its manufacturing operations company-wide, with a focus on its growing submarine construction business. A plurality of this year's capital expenditures – the reinvestment in manufacturing operations, commonly referred to as CapEx – will focus on making improvements to General Dynamics Electric Boat, the maker of the Virginia-class attack submarines and the new Columbia-class ballistic-missile submarines. “We are poised to support our Navy customers and increase the size of the fleet,” Phebe Novakovic, the chief executive of General Dynamics, said during a conference call with analysts today to discuss the company's 2018 financial results and detail financial expectations for 2019. Submarine builder Electric Boat is on pace to build two Virginia-class Block IV submarines a year while preparing to start building the first Block V submarines. At the same time, Electric Boat is preparing for construction of the first Columbia-class submarine to begin in early 2020. “CapEx will be 3 percent of sales in 2019 mostly because of the Columbia-class construction,” Jason Aiken, the chief financial officer of General Dynamics, said during the call. In 2018, General Dynamics reported sales of $36.2 billion, and the company predicts sales to increase in 2019. General Dynamics capital investments will remain at a similar level for the next two to three years, Aiken said. After 2022, once Columbia-production is ramped up, the level of capital spending is expected to taper off, he added. Overall, the company's Marine Systems division, which includes the Electric Boat, Bath Iron Works and NASSCO shipyards, recorded robust sales growth during the year, and Novakovic said the sales growth is expected to continue in 2019. The Pentagon and Capitol Hill are sending signals that Novakovic said she takes to mean, “we'll see nice defense spending for our programs.” General Dynamics predicts the Marine Systems division will post 2019 sales of $9 billion, a 6-percent increase over sales in 2018. The Marine Systems group has a backlog of 11 Arleigh Burke-class guided-missile destroyers; started construction on the future USNS John Lewis (T-AO-205), a first-in-class oiler for the Navy; and continued building Expeditionary Sea Base ships. “They have done nicely with slow, steady growth, but the real growth driver is Electric Boat,” Novakovic said. https://news.usni.org/2019/01/30/40759

    Here’s what’s behind France’s 72% jump in weapons exports

    By: Christina Mackenzie PARIS – France's spectacular 72 percent jump in weapons' exports in the 2015-2019 period from five years prior is largely thanks to two companies: Dassault Aviation and Naval Group. The first of those companies sold Rafale fighters to Egypt, India and Qatar, while the second has become the most successful exporter of warships in the world — if one includes orders — selling submarines to Brazil and India, frigates to Malaysia and the United Arab Emirates, and mine-sweepers to Belgium and the Netherlands. A report released on March 9 by the Stockholm International Peace Research Institute notes that “French arms exports reached their highest level for any five-year period since 1990 and accounted for 7.9 percent of total global arms exports in 2015-19.” Diego Lopes Da Silva, a SIPRI researcher adds: “The French arms industry has benefited from the demand for arms in Egypt [which accounted for 26 percent of France's defense exports], Qatar and India [14 percent each].” Both politicians and defense industry leaders in France have understood that without exports they cannot afford to provide France's own armed forces with the most innovative and high-performing weapons. Furthermore, buying weapons from the United States brings red tape, including requirement for congressional authorization on all foreign military sales, which can delay the process and some argue shackle France's sovereignty. In the words of Hervé Guillou, the out-going CEO of Naval Group, “no European country can maintain the competitivity of its defense industry based on just its own domestic market.” https://www.defensenews.com/global/europe/2020/03/10/heres-whats-behind-frances-72-jump-in-weapons-exports/
