    A Senate panel wants to spend an extra $400 million on microelectronics

    By: Daniel Cebul When the Senate Appropriations subcommittee on defense released a summary of their spending priorities June 26, the bill included a significant increase for one emerging technology. The panel recommended setting aside an additional $447 million for microelectronics. Specifically, the committee wanted to ensure the Department of Defense has access to trusted microelectronics and can develop manufacturing processes for next-generation microprocessor chips. To do so, the bill raised the fiscal year 2019 research, development, testing and evaluation budget for microelectronic technology from $169 million in the president's fiscal year 2019 budget request to $616 million. Already, concern about the domestic production of microelectronics is expected to be part of a large defense industrial base review now underway. But what exactly are microelectronics, and why is their development worth so much to DoD? Microelectronic chips are essentially integrated electric circuits that regulate energy consumption, and perform complex computations that enable capabilities like global positioning systems, radar and command and control. Imagine all of the components that go into your computer ― memory, graphics processors, wifi modules, etc ― all on a single silicon chip, called a wafer. eading-edge wafers typically are 300 mm in diameter and loaded with transistors, resistors, insulators and conductors that control the flow of electrons (read electrical energy) across the chip. The smaller and smaller these components are, specifically transistors, the more can be fit on a chip, enabling faster and more efficient processing. Transistors themselves are measured in nanometers (nm), and are unfathomably small to most non-scientists and engineers. One nanometer equates to a billionth of meter! To put that into perspective, the average diameter of a human hair is 75,000 nm. The most cutting-edge transistors used in microelectronics measure between 10 and 7 nm, and are expected to get smaller in coming years. Smaller and smaller transistors will contribute to breakthroughs in “machine learning, data sorting for recognition of events, and countering electromagnetic threats,” according to a Defense Advance Research Project Agency backgrounder. Because Pentagon leaders believe this technology is vital for current and future capabilities, technology officials say it is important DoD can trust microelectronics are reliable and secure from adversary attacks and sabotage. For this reason, DARPA launched the five-year, up to $200 million Electronics Resurgence Initiative in September 2017 “to nurture research in advanced new materials, circuit design tools, and system architectures.” A key thrust of this initiative is partnership with top universities through the Joint University Microelectronics Program, or JUMP. The program enlists top researchers to work on proejcts like cognitive computing, secure cellular infrastructure to support autonomous vehicles and intelligent highways and other technologies enabled by microelectronics. Under the Senate defense subcommittee's markup, ERI received an additional $30 million to help “reestablish U.S. primacy in assured microelectronics technology.” https://www.c4isrnet.com/it-networks/2018/06/28/a-senate-panel-wants-to-spend-an-extra-400-million-on-microelectronics/

    Building on a successful fifteen-year relationship, Her Majesty’s Armed Forces awards a new framework contract with Rheinmetall in the field of infantry ammunition

    On 6 June 2019, Rheinmetall AG and Defence Equipment and Support, the UK's defence procurement agency, signed a new framework agreement to enable the repeat procurement of infantry ammunition. The framework agreement will represent the default source of supply for specific impact rounds, ammunitions and grenades in the next 5-7 years and has an estimated throughput of up to €100 million (£90m). Rheinmetall continues to expand its role as a major supplier of ammunition. Only a few days ago, the Dutch armed forces also renewed a partnership agreement for the supply of ammunition with the Düsseldorf-based specialist for security and mobility technology, which runs through to the end of 2030. The contract, which has now been renewed with the British procurement authorities, establishes Rheinmetall as the preferred supplier of 25 infantry ammunition products produced by four manufacturing locations in Germany and Switzerland. Simon Valencia, Sales Director Rheinmetall Weapon and Munitions UK commented “we are delighted to be able to renew our long standing supply agreement with the UK MoD and provide the British Armed Forces with high quality, reliable, products that have been proven both operationally and in training for the last fifteen years. This new contract provides the UK MoD with value for money and continued confidence in re-supply of assured munitions products. The UK MoD is a key strategic partner for Rheinmetall and this new contract supports Rheinmetall's continued growth into the UK Defence Market”. Defence Equipment and Support (DE&S) is currently is the process of negotiating a portfolio of framework agreements with defence suppliers to enable repeat procurement of in-service munitions. The contract with Rheinmetall Defence is the first contract DE&S has agreed with the munitions industry on framework terms and marks a positive step change in the way UK MoD engages with industry. https://www.rheinmetall-defence.com/en/rheinmetall_defence/public_relations/news/latest_news/index_20864.php
