    German government asks Lockheed, MBDA to rebid on missile defense system

    By: Sebastian Sprenger COLOGNE, Germany — The German government has given Lockheed Martin and MBDA the go-ahead to bid anew on the TLVS air defense program. The latest request for a proposal, transmitted Wednesday, is the third iteration after previous attempts to draft a contract failed. If the vendor team decides to pursue the business, a new offer is expected by the summer. A Lockheed spokesman confirmed receipt of the solicitation but said the company could not comment further. The program, short for Taktisches Luftverteidigungssystem, is meant to wean Germany off the venerable Patriot air defense weapon. Formerly developed in concert with the United States and Italy, TLVS boasts a 360-degree sensing and shooting capability meant to lower its footprint in the field and allow for intercepts against threats from all directions. The Germans want a system that grants its military operators maximum national autonomy, meaning the government wants to own the rights to relevant software and hardware without having to consult with Washington to employ or modify the weapon. That requirement previously turned out to be a major headache in the negotiations with industry, especially relating to the Lockheed-made interceptor known as the Patriot Advanced Capability-3 Missile Segment Enhancement. It also remains to be seen how firmly Berlin sticks to its guns on the issue in the upcoming round of talks. News of movement in the prospective multibillion-dollar program comes as the German Defence Ministry announced another major acquisition decision last month that continues to make headlines. The government has proposed a split buy of Eurofighter and F-18 fighter jets to replace its Tornado fleet by 2030, prompting spirited debates among German lawmakers, industry advocates and analysts. https://www.defensenews.com/global/europe/2020/05/06/german-government-asks-lockheed-mbda-to-re-bid-on-missile-defense-system/

    From shelters to vehicles to rucks, here’s how the Army is changing its command posts

    By: Todd South ABERDEEN PROVING GROUND, Md. — As the Army looks to shrink its battlefield footprint, its researchers and engineers are finding ways to make the nerve center of the battle — command posts — lighter, more capable and easier to set up and tear down. A recently concluded three-year program aimed to do just that, with everything from the shelter devices used to house a command post's gear, to refitting old and new vehicles, to moving an entirely vehicle-mounted communications system off the truck and into the ruck, cutting its weight by two-thirds in the process. These are some of the ways that experts with the U.S. Army Research, Development and Engineering Command's Communications–Electronics Center are finding to make command posts more mobile, resilient and effective against enemies that can quickly target and destroy massed formations. Some of the advancements include the Expeditionary Command Post shelter, a 20-foot box with integrated power outlets, air conditioning, network cabling and video distribution system. It's containerized so that it can be hauled on a truck or sling loaded under a helicopter. A four-soldier team can set up the structure within 30 minutes as the remaining command personnel hook up the computers, radios and other devices inside of the structure. Jim Bell, operations expert with RDECOM, told Army Times that soldiers with the 1st Armored Division's 2nd Brigade Combat Team set up the shelter in those time frames during field exercises. And during an experiment at Fort Hood, Texas, soldiers moved the shelter with a CH-47 Chinook helicopter. An even more mobile option that researchers have put together is the Light-Mobile Command Post, a pull-out table and tent combination that is installed in the back of a Humvee. It includes fixed TV monitors, built-in radio networks, cabling and computers. The system was designed primarily for light infantry units, but a similar configuration has also been installed on tracked command vehicles for armor units. This post can be voice comm and position location tracking operational within 15 minutes and fully operational in 30 minutes. Another Humvee-based answer to mobile command is a reconfigured command and control vehicle dubbed the Command Post Platform–Improved. It has a built-in power and cooling system and spots for two cases containing the capacity for six computer servers, enough to run a brigade's worth of data. The setup includes seven radio nets, HF, UHF, VHF and SATCOM, and links for fiber optic, standard and secret lines of communication. A small but important feature allows the user to power the systems from either vehicle or external power. The system also has a 15-minute power backup so that the servers can continue to run as power is switched. Beyond a structure or tent solution, researchers have also outfitted small and mid-size all-terrain vehicles, specifically the Polaris MRZR. The focus of these is to provide airborne or air assault operations with a full-fledged command post in a smaller package. The smaller MRZR uses a modular system that can be pulled and reinstalled quickly into another vehicle, should the ATV be disabled. And it has an extra-powerful alternator that can produce 120 amps, double the amperage of a Humvee alternator. It also includes a first-ever all-around handset that can plug in and communicate whether the speaker is using radio, Voice over Internet Protocol or VOIP, and other computer-based voice applications. On top of all these advancements, the Army also is working on reducing what was 60 pounds worth of gear that previously was only used during mounted operations into a much lighter, man-portable package. “They were ripping stuff off of vehicles and coming up with a power source,” said Brad McNeilly-Anta, command post consultant for RDECOM. “That wound up with a 60-pound item, and they were jumping with it at the 82nd Airborne.” Not the most convenient package to haul to the ground. The expeditionary Joint Battle Command Platform is a line of sight, two-way transmission that includes a tablet, battery, peripherals and a new fueled power source that allows it to run for more than 24 hours of continuous operations. Adjustments and replacements to the ruggedized computer, power source, transceiver and encryption device have trimmed the weight down to 23 pounds. Experimenters adapted a 1 L methanol power source to run the system but have also successfully experimented with windshield wiper fluid to run the system, McNeilly-Anta said. https://www.armytimes.com/news/your-army/2018/07/26/from-shelters-to-vehicles-to-rucks-heres-how-the-army-is-changing-its-command-posts
