    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.

    Competitors protest awards to SpaceX and L3Harris for hyperonic weapon tracking satellites

    Nathan Strout WASHINGTON - Raytheon and Airbus are protesting two recent awards for eight missile tracking satellites issued to SpaceX and L3Harris, putting into question the Space Development Agency's tight schedule to get its initial constellation on orbit in 2022. The news was first reported by Aviation Week. Under the Oct. 5 award in question, SpaceX and L3Harris were issued contracts to design and develop four satellites equipped with wide field of view (WFOV) overhead persistent infrared (OPIR) sensors. The eight satellites would form tranche 0 of SDA's tracking layer, which the military is building to track hypersonic weapons from space. L3Harris received $193 million, while SpaceX received $149 million. Airbus U.S. Space & Defense first filed its protest of the award Oct. 28, while Raytheon filed its own protest on Nov. 3. A stop work order has been issued for SpaceX and L3Harris. “SDA is working with the GAO to achieve fast, accurate and equitable resolution to the protests received from Airbus and Raytheon on the agency's Tracking Tranche 0 contracts," an SDA spokesperson said in a statement. “SDA is committed to full and open competition whenever practicable and the agency understands protests are a potential and not uncommon part of that process.” The tracking layer is one of several capabilities being built into the agency's planned mega-constellation known as the National Defense Space Architecture. SDA is using a spiral development approach to build out that constellation, by adding more satellites every two years. The first tranche, which would include the eight missile tracking satellites in question, will include about 30 satellites set to launch in 2022. By the end of 2026, the agency wants to have hundreds of satellites in orbit. While Raytheon declined to comment, Airbus U.S. Space & Defense told C4ISRNET in a statement that concerns over the government's evaluation process for the proposals led the company to protest the award. “While determined highly competitive, Airbus U.S. Space & Defense, Inc. was ultimately not selected by SDA for award. Our post-award debrief review identified concerns about the government's evaluation process, and as a result, we have filed a protest with the U.S. Government Accountability Office (GAO),” an Airbus U.S. spokesperson said in a statement. “Airbus U.S. believes its proposal based on the ARROW commodity satellite bus and the Airbus OneWeb Satellites' operational manufacturing facility in Florida fits SDA's evaluation criteria for commercial commoditized buses manufactured at scale.” At the time of the awards, SDA Director Derek Tournear told C4ISRNET the awards were the result of a full and open competition, with the selection based purely on technical merit. Tournear praised both SpaceX and L3Harris in that interview, emphasizing both companies' plans to meet the agency's aggressive schedule. “SpaceX had a very credible story along that line — a very compelling proposal. It was outstanding,” he said. “They are one of the ones that have been at the forefront of this commercialization and commodification route.” In addition, “L3Harris had an extremely capable solution. They have a lot of experience flying affordable, rapid, small satellite buses for the department,” he said. “They had the plant and the line in place in order to produce these to hit our schedule.” https://www.c4isrnet.com/battlefield-tech/space/2020/11/06/competitors-protest-awards-to-spacex-and-l3harris-for-hyperonic-weapon-tracking-satellites/
