New US Army radios show anti-jam progress at network experiment
WASHINGTON — The U.S. Army is seeing improvements in anti-jam capabilities in new radios crucial to securing manned-unmanned communications at its annual Network Modernization Experiment.
At NetModX '20, which runs from late July to early October at Joint Base McGuire-Dix-Lakehurst in New Jersey, the Army's Combat Capabilities Development Command's C5ISR Center — or Command, Control, Communication, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance Center — is testing the resiliency of the new radios. The effort will help the service observe how they would perform in the field as the Army looks to partner humans and machines.
Initial data from the event suggests the two companies involved — Silvus and Persistent Systems — have improved their radio capabilities from last year, specifically in regard to anti-jam, according to Daniel Duvak, chief of the C5ISR Center's Radio Frequency Communications division.
But one major challenge is making the radios less detectable as the Army's tactical network team starts to focus on command post survivability — or reducing the electromagnetic signature of command post communications — while not sacrificing latency and throughput.
“If you want to make it less detectable, you know oftentimes you have to trade off the throughput or the range or one of those other products,” Duvak said. “So that's the piece and the real technical challenge that they're continuing to work on over the next few months. We've seen progress that they've made in those areas, but that's the piece that they're still working on.”
Robert Stevens, an electronics engineer at the Radio Frequency Communications division, told C4ISRNET that the radios are an important piece of the next-generation combat vehicle. And Duvak said the Army's tactical network modernization team — made up of the Network Cross-Functional Team and Program Executive Office Command, Control, Communications-Tactical — wants to use the radios as a mid-tier radio solution.
The development and fielding of new science and technology projects can take more than five years; however, the Army wants to speed that up as it seeks to modernize systems in preparation for future conflicts with near-peer adversaries. At last year's Network Modernization Experiment, the C5ISR Center tested several vendors' radios to see where commercial technology stood.
Alternative contracting options, like broad agency announcements as well as cooperative research and development agreements, have proved critical to quickening radio development. Under the contracting mechanisms, vendors and the Army have more flexibility to experiment with radios and make iterative modifications as requirements change.
Duvak said this is different from how the Army did business years ago, when it would award yearslong contracts but eventually receive radios that no longer met current requirements.
“What we were able to do at this program was, in just about a year and a half of development time, take a couple of those products that we saw that were very promising and we were able to add and actually fund vendors to enhance those radios with those resiliency features that we were just talking about for the contested environment,” Duvak said. “Things like making them anti-jam, or more difficult for the adversary to jam, making them more difficult for the adversary to detect or intercept our communications.”
Duvak said the Army wants the new radio capabilities for Capability Set '23, a collection of new tactical network tools to be fielded to soldiers in fiscal 2023. The resiliency of communications is critical as the tactical network modernization team pivots to reduce the electronic signature of the service's command post under Capability Set '23. The team is looking to increase bandwidth and reduce latency as part of that set of tools.
Preliminary design review for Capability Set '23 is scheduled for April next year.

Turkish industry prospers, but foreign relations are limiting its potential
By: Burak Ege Bekdil   ANKARA, Turkey — The official numbers are impressive. In President Recep Tayyip Erdogan's narrative, the number of Turkish defense industry programs rose from 62 in 2002 to 700 today. In the same period, the number of defense and aerospace companies rose from 56 to 1,500. The government was administering $5.5 billion worth of programs then; now this is at $75 billion. Local industry turnover rose from $1 billion to $10.8 billion; and exports jumped from a mere $248 million to more than $3 billion. Two Turkish companies that weren't on the Defense News Top 100 list last year have made their way onto the list this year, making the total number of Turkish firms on the list to seven, from five the year prior. Those companies are military electronics specialist Aselsan (48th on the list), Turkish Aerospace Industries (53th), armored vehicles maker BMC (89th), missile maker Roketsan (91st), military technologies specialist STM (92nd), armored vehicle maker FNSS (new this year at 98th) and military software specialist Havelsan (new this year at 99th). Of the seven, five are government-controlled companies. BMC, a Turkish-Qatari partnership, and FNSS are privately owned. A success story, by any criteria. Thanks to which, according to the Turkish government, the country's dependence on foreign defense systems plunged from 80 percent to 30 percent. Erdogan says he aims to end dependency on foreign systems by 2023, the centennial of the Turkish republic. However, while the Turkish defense industrial base has made progress, there have been lingering roadblocks along the way. It can be difficult to determine the percentage of foreign input in a system. And what the Turkish authorities portray as “indigenous systems” (or 100 percent national systems, in local jargon) are often not. One of the major weaknesses of the Turkish industry is the lack of engine technology. For instance, one of Turkey's most prestigious “indigenous” programs, the Altay tank, is struggling to make progress, despite a serial production contract, due to the lack of a power pack — the engine and the transmission mechanism. Similarly, Turkey's most ambitious indigenous program — the design, development and production of a national fighter jet, dubbed TF-X — appears stalled, as Turkish aerospace authorities are yet to find an engine for the planned aircraft. The TF-X program was officially launched in December 2010. In January 2015 then-Prime Minister Ahmet Davutoglu announced that the planned fighter would have a twin engine. That was when the search for an engine began. The amphibious assault ship TCG Anadolu, the Turkish Navy's flagship vessel under construction with license from Spain's Navantia, is progressing as planned, but industry experts say it is no more than 60 percent Turkish-made and is a copy of the Spanish Navy warship Juan Carlos I. Turkey's indigenous T129 attack helicopters are a Turkish variant of the A129 built by the Italian-British company AgustaWestland. The T129 is produced under license from AgustaWestland. A $1.5 billion export deal with Pakistan for a batch of 30 T129s has long been stalled as it awaits U.S. export licenses, which is required because the helo is powered by an American engine. For the past decade, Turkey's local industry has been unable to produce a national solution for the need for long-range air and anti-missile defense systems. After years of uncertainty Turkey signed a $2.5 billion deal for the acquisition of the Russian-made S-400 system. In response, the United States ejected Turkey from the American-led multinational Joint Strike Fighter program that builds the F-35 fighter jet. “That will cost the Turkish industry critical capabilities it could have earned during the production cycle,” a Western industry source in Ankara told Defense News. “It also means a loss of significant income for the Turkish industry.” Otherwise, local and international analysts agree that drone, shipbuilding, military electronics and armored vehicles technologies have been progressing exponentially in Turkey. The country has found foreign customers for these systems due to high technological standards and competitive pricing. The combat-proven technologies easily find their place in export markets, especially in countries with which Turkey has friendly political relations. Lucrative markets for Turkish companies include those in Qatar — Turkey's most important regional ally — as well as some north African countries, Azerbaijan, Pakistan, Turkic republics in Central Asia, and Muslim countries in southeast Asia like Indonesia and Malaysia. Turkish exporters have been augmented by a steady decline of the country's national currency. The U.S. dollar was trading at 1.7 Turkish liras five years ago. Today, the exchange rate is $1 to 7 liras. That plunge gives an exchange rate boost to companies with higher local input rates and export potential. In other words, when the local currency experienced a decline, the commodities produced in Turkey generally became cheaper for foreign customers. However, those companies dependent on now pricey foreign technology have seen their international competitiveness badly pruned. The lira's slide downward also slows or altogether suspends government-run programs due to a cash shortage. Overseas investors have withdrawn $7 billion from Turkey's local currency bond market in the first six months of 2020. The economy is in recession, and inflation and unemployment rates are soaring. At the end of May 2020, Turkey's national budget produced a deficit of 90.1 billion liras (U.S. $12.9 billion), or 65 percent of the government's deficit target for the entire year of 2020. That macroeconomic picture may further squeeze the government in financing its weapons programs, economist warn. https://www.defensenews.com/top-100/2020/08/17/turkish-industry-prospers-but-foreign-relations-are-limiting-its-potential/
