  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.

  Can a dragonfly teach a missile how to hunt?

  By: Jen Judson WASHINGTON — A computational neuroscientist is studying whether a dragonfly's excellent hunting skills can be replicated in a missile's ability to maneuver and destroy targets midair with better precision. Dragonflies are vicious little creatures with a hit-to-kill track record of 95 percent, meaning only 5 percent of its prey escapes. Sandia National Laboratories' Frances Chance is building algorithms that simulate how a dragonfly processes information when intercepting prey, and she's testing them in a virtual environment. So far, the results are promising. The laboratories are federally funded and focus on national security missions through scientific and engineering research. The project is a yearlong, high-risk, high-gain effort that will wrap up in September, and it is funded by Sandia's Autonomy for Hypersonics Mission Campaign, Chance said. “I think what is really interesting about insects, in general, is they do something really fast and really well, but they are not particularly smart in the way you or I would think of ourselves as being smart,” Chance told Defense News in a recent interview. While insects may not be the right fit for studying cognitive capabilities to develop complex artificial intelligence, they are ideal for developing efficient computations for intercept capability. A dragonfly can react to a particular prey's maneuvers in 50 milliseconds, Chance explained. That amount of time accounts for information to cross three neurons in a dragonfly's brain. This indicates the dragonfly doesn't learn how to hunt, but rather the skill is inherent and part of its brain's hard-wiring. “The challenge then is: Is there anything that we can learn from how dragonflies do this that we can then bring to the next generation of missiles, or maybe even the next-next generation of missiles?” Chance said. By developing an artificial neural network that mimics a dragonfly's ability to hunt and then applying it to missile capabilities that rely on computation-heavy systems, one could reduce the size, weight and power needed for a missile's onboard computers; improve intercept techniques for targets such as hypersonic weapons; and home in on targets using simpler sensors. If the model of a dragonfly's neural circuit developed through Chance's research shows enough promise, she would then pass the information to scientists, who would try to directly apply it to weapons systems. One of the greatest leaps involves adapting an algorithm to handle the speed at which a missile flies. While a dragonfly is fast, it's not nearly as fast as a missile. Animal brains process information significantly slower than a computer, so it's possible computations can be sped up to better align with the speed at which a missile approaches targets. “The hope is that even if the algorithm isn't wildly successful, you might be able to say something about what you can get away with in terms of what types of capabilities you give the next generation of weapons,” Chance said. The model she's building is several steps removed from implementation onto a weapon. “I would consider the project complete when we have a viable model — ‘viable' meaning it does interception — and a bonus if it's neurobiologically plausible. There is no reason to force that for this type of research, but only because it doesn't necessarily matter; so something biologically inspired that works I would consider a success.” https://www.c4isrnet.com/land/2019/08/05/can-a-dragonfly-teach-a-missile-how-to-hunt/
