    Space Force lays out acquisitions reforms in new report

    Nathan Strout In a new proposal, the U.S. Space Force is asking Congress to overhaul the tools it uses to acquire new space systems, allowing the new service to move with more agility and keep pace with near-peer adversaries. “Our nation requires a bold Alternative Space Acquisition System that not only matches the pace of change but also manages unpredictability and regularly disrupts our adversaries' threat cadence," the Department of the U.S. Air Force report concludes. “The features outlined in this report will create a new space acquisition approach for the USSF that is the envy of all other services and ultimately enables the USSF to rapidly leverage industry innovation to outpace space threats.” When Congress passed legislation establishing the Space Force as the nation's sixth branch of the armed services in December, it included a provision requiring the Secretary of the Air Force to provide a report by the end of March on whether the military should adopt an alternative space acquisition system. While the Pentagon did deliver a report to Congress in March, it largely kicked the can down the road on any specific acquisitions reforms. Space Force leadership have touted this more detailed acquisitions report as “groundbreaking” in recent appearances. The new report, which was first reported by Bloomberg Government, includes nine specific proposals to improve Space Force contracting, although it doesn't make any suggestions towards unifying the various organizations involved in purchasing space platforms and systems, such as the Space Development Agency, the Space Rapid Capabilities Office, the Space and Missile Systems Center, or the National Reconnaissance Office, which purchases satellites for the intelligence community. Instead, the report's recommendations include changes to the contracting tools and reporting requirements the Space Force will use to acquire new systems, with a focus on increasing flexibility and delegating authority. Three of the suggestions require legislative action, while the remaining proposals will simply require internal Department of Defense adjustments. Perhaps the most important recommendation in the report, according to the Air Force, is the consolidation of budget line items along mission portfolios, such as missile warning or communications, instead of by platform. While this has been done on a limited basis in the past for the Space Rapid Capabilities Office and some classified efforts, it marks a change from standard DoD budgeting practices. Theoretically, this would allow the Space Force to move funding between missile warning systems without having to submit reprogramming requests to Congress, something it did several times last year in order to move up the delivery date for the first Next Generation Overhead Persistent Infrared satellite. The Air Force's repeated reprogramming requests rankled some members of Congress, leading to a fight between lawmakers and the White House over the program's funding for fiscal 2020. The Air Force claims this fix is needed to give program managers the flexibility to adapt to growing threats. According to the report, transparency at the program level would be preserved in future budget documents. This change would not require legislation. Beyond that, the Air Force is asking Congress for permission to push milestone decision authority down the chain of command, similar to what's been demonstrated by the Missile Defense Agency and National Reconnaissance Office. This change would speed up decision making for space programs. The third major change the Air Force is pursuing is authority for the Space Force to use incremental funding for space systems and programs. This “Efficient Space Procurement” coding was used to acquire the fifth and sixth satellites in the Advanced Extremely High Frequency satellites at the same time as well as the fifth and sixth Space-Based Infrared System satellites, resulting in significant savings. The department claims full funding each space vehicle has lead to affordability issues in the past, and can “lead to production breaks, obsolescence, and industrial base impacts.” Instead, the department wants to spread out funding for satellites over multiple years to help keep costs in check and avoid funding spikes. Other changes include streamlining requirements validation and reporting requirements. “Under these reforms, our Nation's newest military service will have unprecedented agility to build resilient, defendable, and affordable space capabilities through streamlined processes and closer partnerships with one of America's decisive advantages—its innovative and rapidly changing commercial space industry,” Secretary of the Air Force Barbara Barrett wrote in the introduction to the report. https://www.c4isrnet.com/battlefield-tech/space/2020/05/21/space-force-lays-out-acquisitions-reforms-in-new-report/

  • State clears $1.5 billion in arms sales for Egypt, South Korea and Canada

    State clears $1.5 billion in arms sales for Egypt, South Korea and Canada

    By: Aaron Mehta WASHINGTON — The U.S. State Department today cleared a trio of weapon sales for Egypt, South Korea and Canada, which could net American firms more than $1.5 billion in revenues. Announcements for the three deals were published online by the Defense Security Cooperation Agency. DSCA announcements are not final sales; if cleared by Congress, contract figures can change during future negotiations. The largest of the three agreements is with South Korea, which was ok'd to receive contractor logistics support for its fleet of RQ-4 Block 30 unmanned systems. That comes with an estimated cost of $950 million. Northrop Grumman will be the prime contractor on the work, with offset requirements to be determined later. For more on the state of the defense industry, check out the Defense News Top 100 Northrop's work order will cover “program management; training for pilots maintenance, logistics and communications personnel; depot and organizational level maintenance; minor modifications and upgrades; spares and repair/return parts; operational flight support; program analysis; publications and technical documentation; U.S. Government and contractor technical and logistics services; and other related elements of logistics and program support,” per the DSCA. Egypt's deal involves follow on technical support for a variety of ships in its navy. Work will cover Egypt's fleets of Oliver Hazard Perry class frigates, fast missile craft, coastal mine hunter ships, and 25 meter and 28 meter fast patrol craft. The prime contractor will be the Virginia-based VSE Corporation, with an estimated price tag of $554 million. Finally, Canada is looking to buy 152 American-made radios, for $44 million. Known formally as the Multifunctional Information Distribution System - Joint Tactical Radio System, the radio is Link 16 enabled, an important capability for the NATO ally. “Canada intends to upgrade its current inventory of CF-18 aircraft, CC-130J, and the Royal Canadian Air Force's ground stations with the purchase of these MIDS JTRS (5) terminals to be fully interoperable with U.S. and allied forces to support and compliment joint operations in a net-enabled environment; have modernized electronic protection and secure, jam-resistant wave forms; and be capable of improved Link 16 message exchange and information fidelity including support to advanced weapon employment,” the DSCA announcement says. Primary vendors are Viasat and Data Link Solutions, and some form of industrial offset is expected. https://www.defensenews.com/global/mideast-africa/2019/07/30/state-clears-15-billion-in-arms-sales-for-egypt-south-korea-and-canada/

  • Indian MoD approves procurements worth USD1.17 billion

    Indian MoD approves procurements worth USD1.17 billion

    by Rahul Bedi India's Ministry of Defence (MoD) has approved the procurement of indigenously developed platforms and weapon systems worth INR87.22 billion (USD1.17 billion) for the country's three military services, including basic trainer aircraft for the Indian Air Force (IAF). The Indian government's Press Information Bureau (PIB) announced on 11 August that the MoD's Defence Acquisition Council (DAC), which is headed by Minister of Defence Rajnath Singh, agreed to acquire an initial 70 Hindustan Turbo Trainer-40 (HTT-40) aircraft from public-sector company Hindustan Aeronautics Limited (HAL) following their certification. An additional 36 tandem-seat HTT-40s are expected to be acquired thereafter, once the IAF has operationalised the first lot of trainers. A HTT-40 prototype powered by a Honeywell TPE331-12B turboprop engine made its maiden test flight in June 2016, following a six-year delay, but the aircraft has yet to enter series production. The HTT-40 was developed to replace the HAL-designed HPT-32 Deepak, which was grounded in July 2009 following recurring accidents. Once inducted, the HTT-40 is meant to supplement 75 Pilatus PC-7 Mk II basic trainers that have been in IAF service since 2013. The DAC also cleared the procurement of an unspecified number of upgraded 127 mm/64 cal ‘super rapid' guns from state-owned Bharat Heavy Electricals Limited (BHEL) for fitment onto Indian Navy (IN) and Indian Coast Guard (ICG) vessels. Industry sources told Janes that the IN plans to arm an initial 13 frontline warships – including the indigenously designed and built Shivalik-class frigates and Delhi-class destroyers – with these guns. https://www.janes.com/defence-news/news-detail/indian-mod-approves-procurements-worth-usd117-billion
