    Heavy polar icebreaker questions mount for Coast Guard

    By: Andrew C. Jarocki WASHINGTON ― Potential funding woes and questions about the aggressive proposed timelines have cast doubts about the future of the Coast Guard's new heavy polar ice breaker. The Government Accountability Office is dubious the service's lone heavy polar icebreaker can make it to its proposed 2023 retirement date and questioned whether the Coast Guard's construction schedule was too optimistic. The Coast Guard is planing to replace the Polar Star with the new heavy icebreaker the same year, something GAO said may not be “realistic and feasible.” The watchdog noted the aging Polar Star could reach the end of its service life as soon as 2020, and the “highly optimistic” delivery date of the new vessel could be delayed and leave the service without a heavy polar icebreaker to defend strategic Arctic interests for several years. Vice Adm. Daniel Abel, deputy commandant for operations, recently told the Coast Guard and Maritime Transportation Subcommittee at a hearing that the Polar Star is “limping along, and nothing with a US flag could rescue her [in the Arctic] if something happened, putting our polar capabilities at risk." To further complicate matters, House appropriators are currently debating cutting $750 million in funding for the Coast Guard. Vice Adm. Michael McAllister, deputy commandant for mission support, said at the hearing that the entire program schedule is at risk if the appropriations cut is finalized but that he remained confident that the Coast Guard is “well-poised to award the detailed construction contract in fiscal year 2019” for the heavy polar ice breaker. https://www.defensenews.com/naval/2018/07/26/heavy-polar-icebreaker-questions-mount-for-coast-guard

  • Rheinmetall supplies South African National Defence Force with new 40mm medium-velocity ammunition

    Rheinmetall supplies South African National Defence Force with new 40mm medium-velocity ammunition

    November 13, 2020 - Rheinmetall is supplying the South African military with new 40mm medium-velocity ammunition, underscoring its role as the world's leading one-stop-shop for 40mm ammunition systems. In October 2020 Rheinmetall Denel Munition officially completed Project Kamogelo on behalf of the South African Department of Defence, Armscor and the South African Army. What makes Project Kamogelo so special is not only the introduction of a new 40mm medium-velocity (MV) weapon system: it also marks the first successful Expedited Armament Acquisition Process (EAAP) project in response to an urgent operational requirement of the South African Army. The South African Army initiated the project in 2016 with the aim of fielding a new grenade launcher and family of 40mm ammunition. Armscor, the nation's arms procurement agency, approved the procurement plan in February 2018, subsequently overseeing testing and evaluation of the Milkor Y4 multi-shot weapon. This involved firing Rheinmetall Denel Munition's less-lethal, low-velocity and medium-velocity ammunition. Particular emphasis was placed on speed and accuracy. The South African Army procured more than 20,000 rounds of medium-velocity ammunition, including high explosive ammunition, high explosive dual-purpose ammunition, practice ammunition, practice tracer ammunition, red phosphorous smoke rounds and orange target marker ammunition. Rheinmetall Denel Munition's medium-velocity ammunition has a maximum range of 800 metres, exceeding conventional extended range low-velocity (LV) variants by up to 375 metres while delivering unparalleled accuracy. The company's ammunition suite currently encompasses nine different MV variants, six of which formed part of this procurement package. “This day marks ... an important milestone in the history of the Department of Defence, in particular the South African Army, as we witness the handing and taking over ceremony of the 40mm medium-velocity grenade launcher,” said Rear Admiral A.A.A. Morris, Chief Director Defence Acquisition Management, Material Division. “We're proud to be able to offer our new medium-velocity 40mm family to our home market, the SANDF. With this solution we offer the soldier a unique product solution: a quick-firing multiple grenade launcher with a standoff range in excess of 800 metres”, said Jan-Patrick Helmsen, CEO of Rheinmetall Denel Munition. Rheinmetall – the leading one-stop-shop for 40mm systems In the infantry toolbox, the versatile 40mm ammunition pallet closes the gap between hand grenade and mortar. It therefore serves as a veritable combat multiplier for infantry and other dismounted troops. Rheinmetall is one of the world's leading suppliers of ammunition, weapon systems and fire control systems and therefore serves as a one-stop-shop for 40mm systems. Widely used today, Rheinmetall's 40mm x 46 low-velocity ammunition (LV, velocity: 78 m/s) is available in many different versions, including HE/fragmentation, shaped charge with fragmentation jacket (HEDP/high explosive dual purpose) as well a number of other service and practice rounds, together with non-lethal payloads such as kinetic impact munitions or irritant. The range of ammunition is constantly being expanded and new capabilities added. With Rheinmetall Denel Munitions's handover, Rheinmetall has taken the first step as the leading maker of new 40mm medium-velocity (MV, ca. 100 m/s) ammunition. The company is currently expanding its MV product. It now includes the new generation of 40mm MV ammunition, which has a maximum effective range of 800 metres, doubling the gunners's operational reach and providing a flatter trajectory for those crucial close-in, accurately placed shots MV ammunition is. Currently undergoing NATO qualification, Rheinmetall's 40mm MV ammunition family will soon be available in service and practice versions. It can be used with the multi-shot grenade launchers Milkor US M32A1 and AV 140. Furthermore, Rheinmetall's 40mm Magazine-Fed Grenade Launcher (MFGL) is currently under development. The Group's 40mm x 53 high-velocity (HV) ammunition reaches a velocity of 240 m/s and has a maximum effective range of 2,200 metres. Here, too, the Group supplies a wide assortment of different cartridges, including newly developed HE and HEDP airburst ammunition programmed by an infrared programming unit. The airburst function also makes this type of ammunition suitable for engaging small unmanned aerial systems. Among other things, it is earmarked for the Bundeswehr's Qualified Air Defence project. Rheinmetall's family of fire control systems enhances combat effectiveness enormously. It provides users with a broad range of enhanced capabilities, increasing the effectiveness of the gunner while maximizing the potential of the host weapon system and the accompanying munitions. The family consists of various fire control solutions, providing increased accuracy and performance: Vingmate FCS 4500 for high-velocity automatic grenade launchers and heavy machine guns, MR-500 and MR-800 for low- and medium-velocity 40mm grenade launchers and Vingmate SL 1000 for shoulder-launched weapons.

    Team Dedrone Wins USSOCOM ‘Game of Drones’ Competition

    Dedrone announced that its team of Echodyne Corporation, Squarehead Technologies and Battelle, won first place at ThunderDrone's “Game of Drones” outdoor demonstration at Nellis Air Force Base and AFWERX enclave, June 18-20. Hosted by AFWERX, Team Dedrone bested five other teams in the last of three ThunderDrone rapid prototyping events focusing on countering small, unmanned aerial drones. Team Dedrone successfully demonstrated the capabilities of a layered detection, tracking, classification and mitigation solution that defends protected airspace against aerial drone threats. Initially 93 counter-drone technology companies formed teams and were narrowed down through a series of three rapid prototyping events. The Dedrone platform is a fully automatic counter-drone solution, designed to detect, classify and mitigate drone-based threats. Dedrone's software, DroneTracker, gathers intelligence from Dedrone's RF sensors, Echodyne's MESA radar and Squarehead Discovair acoustic sensor. Once DroneTracker makes a positive identification of a drone, Battelle's non-kinetic defense system, DroneDefender™, is automatically triggered to defeat the drone and eliminate the threat. The Dedrone platform combines hardware sensors and machine-learning software, providing early warning, classification of and mitigation against all drone threats. Based in San Francisco, Dedrone was founded in 2014. ThunderDrone is a U.S. Special Operations Command and SOFWERX initiative dedicated to drone prototyping, which focuses on exploring drone technologies through idea formation, testing and demonstrating efforts that are being conducted collaboratively with the Department of Defense's Strategic Capabilities Office. SOFWERX leads collaboration between special operations warfighters and select contributors from industry and academia on technology and innovation efforts to bring drones, tactical swarms and their associated data science applications to the special operations community. Team Dedrone Quotes: “Dedrone's open platform and architecture allows customers to combine the best in drone detection and mitigation technology, such as with RF sensors from Dedrone, radar from Echodyne, acoustic sensors from Squarehead, and jammers from Battelle,” shares Joerg Lamprecht, CEO and co-founder of Dedrone. “This multi-layered sensor platform ensures that all organizations, including those under USSOCOM, are provided complete airspace security that is safe from all drone threats.” “ThunderDrone provided us with our first opportunity to simultaneously engage against multiple UAVs with two DroneDefender V2 systems,” shares Alex Morrow, Technical Director of cUAS Programs at Battelle. “Battelle is pleased with another successful demonstration of our DroneDefender V2.” “Echodyne's compact solid-state radar repeatedly demonstrates an unparalleled combination of range, tracking accuracy and value in countering UAS threats,” notes Eben Frankenberg, Echodyne CEO. “We're pleased that our beam steering radar once again contributed its indispensable capabilities as part of the award-winning Team Dedrone solution.” “Discovair's directional acoustics add a near unspoofable layer of super hearing. The ability to deal with drones hinges on detection. In cluttered areas and up against any drone system, even passive ones – Discovair acoustic sensor has proven to shine,” shares Stig Nyvold, CEO of Squarehead Technology. “Discovair's importance as part in the systems of systems has once again been proved. We are very excited to be part of this team and look forward to the future.” https://www.uasvision.com/2018/06/26/team-dedrone-wins-ussocom-game-of-drones-competition/
