  MDA director provides rough sketch of possible space-based missile defense sensor layer

  By: Jen Judson HUNTSVILLE, Ala. — Missile defense leaders within the Pentagon as well as Congress are pushing for more missile defense capability in space and the Missile Defense Agency Director Gen. Samuel Greaves laid out a rough idea of what a space-based missile defense sensor layercould look like. The missile defense community has been talking “seriously” about a sensor layer in space “actively over the last year,” Greaves said in an August 8 speech at the Space and Missile Defense Symposium. While many decisions still have to be made regarding requirements definitions, development paths and the acquisition process, “the key thing,” Greaves said, “is that there is serious consideration and support being given to the need to deploy these space sensors because we must do so.” Greaves laid out a very rough sketch of what the agency is looking for to build a robust sensor layer. First, the MDA might use something like a current system from the U.S. Air Force — the Overhead Persistent Infrared OPIR Global Scanning system — to alert and characterize activity in space, essentially “to be the bell ringer if something is going on,” Greaves said.

  Boeing Makes Third Move Into Metal Additive Manufacturing This Year

  Lee Ann Shay Boeing made another investment in additive manufacturing, this time with the intent of producing higher volume of multi-metal parts faster. Boeing HorizonX Ventures invested an undisclosed amount in Digital Alloys, which created Joule Printing, a metal additive manufacturing technology that uses metal in wire form and high deposition rates to produce the parts. The investment was part of a $12.9 million Series B financing led by G20 Ventures and included other companies. Boeing and Digital Alloys did not disclose the exact investment but Boeing said it “was a minority investor in this round.” Lee Ann Shay | Aug 10, 2018 Boeing made another investment in additive manufacturing, this time with the intent of producing higher volume of multi-metal parts faster.

Boeing and Digital Alloys did not disclose the exact investment but Boeing said it “was a minority investor in this round.” Get Key Developments Delivered to Your Inbox Get Your Sample Edition Digital Alloys holds two patents for Joule Printing, which can use multiple metals into a single part. This could enable new parts designs and improved thermal, electric and mechanical properties. This printing process is “similar to resistive welding and does not result in fully melting the material through external energy sources like lasers, e-beams, or electric arcs. As such, it has the potential to print alloys that have been a challenge with existing printing techniques, but with less energy and a lower machine complexity,” says Boeing. Joule Printing solves “three big problems that are gating the use of metal printing and production:” production costs, printing speeds and complexity, says Duncan McCallum, Digital Alloy's CEO.

  Pentagon redirects $282M to close ISR gaps

  By: Nathan Strout The Department of Defense redirected more than $282 million to intelligence, surveillance and reconnaissance programs in the past two months, largely from a defense-wide operation and maintenance account. The most recently approved reprogramming of $247 million was dated June 21. According to the Pentagon, the action aims to close ISR gaps in the combatant commands. The transfers go to a variety of programs, including artificial intelligence development and developing a bilateral network to share ISR data with strategic partners. In addition to the $247 million from operation and maintenance accounts, the June 21 reprogramming action also transfers $22.5 million to Special Operations Command. That money was made available after ending a program for a signals intelligence sensor effort that originally appeared in the fiscal year 2018 budget. About $13 million of that funding will now provide signals intelligence sensors for use on contractor airborne ISR systems, while another $6.5 million will go toward modernizing an undisclosed maritime ISR system. The remaining funding will go to acquiring and deploying six new sensitive compartmented information facilities. The June 21 reprogramming action follows a $12.25 million reprogramming action May 20. Then, about $7.9 million of that funding went to classified programs, while the remaining $4.3 million went to upgrading AI and machine learning processors in support of pattern of life analysis. Of the more than quarter of a billion dollars in transferred funding, the Army received $31 million, the Navy received $28.6 million, the Air Force received $77.6 million, and the remaining $144.8 million will be spent on defense-wide programs. Meanwhile, the Air Force has announced July 15 that Col. Julian Cheater will be the service's new director of ISR operations. Cheater will work under the deputy chief of staff for intelligence, surveillance and reconnaissance and cyber effects operations, a position created recently as part of the Air Force's reorganization of it's ISR and cyber efforts. https://www.c4isrnet.com/intel-geoint/2019/07/16/pentagon-redirects-282m-to-close-isr-gaps/
