Philadelphia shipyard to build new dual-use merchant mariner training ships
By: David B. Larter
WASHINGTON — A struggling Philadelphia shipyard got a new lease on life April 8 with the announcement that it had been selected to build up to five training ships for the Maritime Administration destined for use by civilian mariners attending state maritime academies.
The contract, issued by Alaska-based company TOTE Services, tapped Philly Shipyard to build the first two national security multimission vessels, or NSMV, for a total of $630 million, according to the trade publication Marine Log.
The ships, which will feature the latest navigation and bridge technologies, will be able to accommodate up to 600 cadets but will also be available for use by the federal government for disaster relief operations. The ships come with a roll-on/roll-off ramp and a crane that can be used for moving equipment and containers.
The NSMVs will be 525 feet long and about 90 feet wide, or just a little smaller than a Ticonderoga-class cruiser, according to a Maritime Administration fact sheet.
MARAD Administrator Mark Buzby said the contract is a win for American shipbuilding jobs.
“Investing in maritime education creates more American jobs,” Buzby, a former Navy flag officer, said in a statement. "By the selection of Philly Shipyard, Inc., as the construction shipyard for the NSMV, this effort is not only bolstering the U.S. Merchant Marine, but the U.S. economy and vital transportation infrastructure as well.”
Philly Shipyard primarily makes Jones Act ships, or vessels that exist only because the Jones Act mandates that goods shipped between U.S. ports must be sent on U.S.-flagged ships built and crewed by Americans. The rule is designed to preserve the domestic shipbuilding industry as a national security asset. Without it there would essentially be no domestic commercial shipbuilding industry.
“Philly Shipyard only received one order per year during the last two years and was in danger of closing during 2020 unless it received additional work,” said Bryan Clark, a senior fellow at the Hudson Institute who recently led a study of the domestic shipbuilding industry.
“Philly is important not just because it is a significant employer in the Philadelphia area, but also because it is one of the shipyards the government depends on to build smaller auxiliary and non-combatant ships such as Coast Guard cutters, NOAA research ships, and Navy unmanned surface vessels, survey ships, and towing and salvage vessels.”
The vessels could also prove useful in the Navy's quest to identify a flexible hull that can meet a number of missions as it seeks to replace its aging logistics fleet, said Sal Mercogliano, a maritime historian at Campbell University.
“I think those vessels serve as a potential hull form for maybe a hospital ship, maybe a command ship, an aviation logistics ship, a sub tender: There's potential there,” Mercogliano said.
The Navy planned to develop and field two variants of a Common Hull Auxiliary Multi-Mission Platform, one for sealift purposes and one for other auxiliary ship missions such as submarine tending, hospital ships, and command-and-control platforms. But late last year, the White House blanched at a cost estimate of upward of $1.3 billion for the submarine tender variant of the CHAMP platform, planned for acquisition in 2024.
For moving lots of tanks and howitzers across long distances, the NSMV isn't well-suited. But for many of the other missions the Navy needs to recapitalize, including its hospital ships, it could prove useful.
“I don't think they'd be good for a roll-on/roll-off — it's not designed for a large mission bay,” Mercogliano said. “But I think for the hospital ship, a command ship, there's a lot of utility there.”

Here’s what the Army wants in future radios
By: Mark Pomerleau Advancements in electronics and tactics by high-end adversaries are forcing the Army to change the way it revamps and optimizes its communications network against current and future threats. The problem: adversaries have become more proficient and precise in the sensing and jamming of signals. “What we're looking for in terms of resilience in the future is not only making individual links more anti-jam and resilient, resistant to threats, but also having the ability to use multiple paths if one goes down,” Joe Welch, chief engineer at Program Executive Office Command, Control, Communications Tactical (C3T), told reporters during a network demo at Fort Myer in early March. “Your phones work this way between 4G and Wi-Fi and that's seamless to you. That's kind of the target of what we're intending to provide with next-generation transport for the Army's tactical network.” Members of industry are now looking to develop radios to these specifications outlined by the Army. “We have an extensive library of waveforms — 51, 52 waveforms that we can bring to bear — that we can say look we can use this waveform to give you more resilience with this capability,” Jeff Kroon, director of product management at Harris, told C4ISRNET during an interview at the AUSA Global Force Symposium in Huntsville, Alabama, in March. “Down the road, we need to talk about resilience and what's going on with the near-peer threats.” Next-generation systems, leaders believe, will be able to provide this necessary flexibility. “The radios that we're looking at buying now — the manpack and the two-channel leader radios — have shown themselves to be able to run a pretty wide range of waveforms and we think it postures us to run some changes to those waveforms in the future as we look at even more advanced waveforms,” Maj. Gen. David Bassett, program executive officer of C3T, told reporters at Fort Myer. While jammers have become more powerful and targeted in recent years, officials contend the entire spectrum can't be interrupted at once. The Army realizes links won't be jam-proof, Bassett told reporters at Fort Myer, so it is looking at how they can be either more jam-resistant or able to switch seamlessly across portions of the spectrum that are not being jammed. Kroon noted that one of the big developments within the radio community down the road will be radios that seamlessly switch frequencies or waveforms without direct user input. “I think, as we move forward, we'll start to have more cognitive capabilities that will allow [the radio] to adapt automatically, and keep the user focused on their own job and let the radio handle the rest,” he said. In addition to multiwaveform and a large range of spectrum coverage, Kroon said the Army is also really looking for multifunction capabilities within radios. Radios also have to have passive sensing capabilities to be able to understand the signals in the environment and provide some level of situational awareness of the spectrum environment. “They have to have visibility into what's going on around them ... not just for [electronic warfare] purposes but sometime just knowing what's going on in the spectrum around you as a planner is really important,” Kroon said. “What's actually going on out there, I don't know I was told this frequency was clear, how do I really know. Having a radio come back and say look what we hit ... it is actually very useful.” https://www.c4isrnet.com/show-reporter/global-force-symposium/2018/04/06/heres-what-the-army-wants-in-future-radios/
