  Fourth GPS III satellite receives operational acceptance in record time

  Nathan Strout WASHINGTON — The fourth GPS III satellite has achieved operational acceptance from the U.S. Space Force at record speeds using an expedited process that was 10 days faster than previous efforts. “[The fourth GPS III satellite] sets a new standard for handover from the contractor launch team to operational acceptance, setting the satellite healthy to the global user community approximately 30 days post launch. Moving forward with future GPS III launches, the timeline between launch and the satellite being set healthy will be at a minimum,” said 2 Space Operations Squadron Flight Commander Capt. Collin Dart in a statement. The satellite was launched Nov. 5 from Cape Canaveral Air Force Station in Florida aboard a SpaceX Falcon 9 rocket. The addition of SV04 to the GPS constellation marks another step toward making M-Code — a more robust GPS signal for military use — available to the war fighter. M-Code provides a more accurate GPS signal with anti-jamming and anti-spoofing capabilities, making it harder for adversaries to block or degrade. Lockheed Martin is the primary contractor for the 10 GPS III satellites and the 22 GPS III Follow-On satellites in development. The Space Force granted GPS IIIF Milestone C in July, clearing the way for production to begin. “M-Code signals are more-secure, harder-to-jam and spoof, and are critical to helping our war fighters complete their missions, especially in contested environments,” Tonya Ladwig, Lockheed Martin's vice president for navigation systems, said in a statement. “GPS III is a war fighting system and we are proud to be helping bring this critical capability to the men and women protecting our nation.” “The highly encrypted M-Code to protect GPS signals from jamming and spoofing is currently enabled on 22 GPS satellites of various generations; 24 are needed to bring the M-Code to the next level of operational capability,” Dart said. “SV04 brings the constellation to 23 M-Code capable vehicles.” The 24th M-Code-enabled GPS satellite, which will be the fifth GPS III satellite, is currently ready for launch. However, the launch is not expected until July 2021 at the earliest. Upgrades to the GPS ground systems and distribution of M-Code-enabled receivers to the field are also needed to get the advanced signal into the hands of war fighters. In addition to moving the constellation closer to M-Code availability, the addition of another GPS satellite to the constellation will provide greater access to the improved L2C and L5 signals to civilian users. “For our billions of civil users, it brings the count up to 23 L2C spacecraft and 16 L5 spacecraft,” said Col. Ryan Colburn, director of the Space and Missile Systems Center Portfolio Architect office's Spectrum Warfare Division. “For professional users with existing dual-frequency operations, L2C enables faster signal acquisition, enhanced reliability, and greater operating range. L5 is broadcast in a radio band reserved exclusively for aviation safety services. It features higher power, greater bandwidth, and an advanced signal design.” And according to Lockheed Martin, the GPS III satellites also include the new L1C signal, which provides improved civilian user connectivity. https://www.c4isrnet.com/battlefield-tech/space/2020/12/03/fourth-gps-iii-satellite-receives-operational-acceptance-in-record-time/

  Watchdog warns Pentagon to fix F-35 tech problems before full-rate production starts

  By: Valerie Insinna WASHINGTON — The F-35 fighter jet is finally cruising toward the end of its development phase, but a congressional watchdog is warning the Defense Department not to move to full-rate production until it's certain it's resolved all critical technical issues. The F-35 Joint Program Office intends to make a decision in October 2019 on whether to move to full-rate production, but had planned to defer certain critical technical deficiencies until after that time, the Government Accountability Office stated in a June 5 report. That could make the program more expensive overall. “In its rush to cross the finish line, the program has made some decisions that are likely to affect aircraft performance and reliability and maintainability for years to come. Specifically, the program office plans to resolve a number of critical deficiencies after full-rate production,” it wrote. “Resolving these deficiencies outside of the developmental program may contribute to additional concurrency costs.” The GAO advised the F-35 JPO to resolve all critical deficiencies before full-rate production — a recommendation with which the JPO concurs and says it will pursue. However, it's important to understand what “resolve” means in this case. “The Department of Defense expects the F-35 Program to resolve all critical deficiencies prior to entering Initial Operational Test and Evaluation (IOT&E), with either a fix, a Service Operational Test Agency approved workaround or a formal acceptance of the deficiency,” the JPO said in a statement. “The full-rate production decision will include an assessment of SDD [development phase] and IOT&E DRs [deficiency reports], as well as follow-on improvement DRs deferred for post-SDD action.” Translation: While the JPO will take steps to address all critical deficiencies, there are some that may require future work in order to be completely fixed. GAO noted that it is common practice for Defense Department acquisition programs to require that problems are “resolved” and not “fixed” because it “affords the department with more flexibility to develop alternative solutions rather than technical fixes.” In a statement, Greg Ulmer, Lockheed Martin's vice president of the F-35 program, said the company was working with the JPO to prioritize and correct issues. The F-35's next stage The GAO report was also critical about the JPO's new plan for Block 4 follow-on modernization, telling its congressional audience that it should consider holding back funding for that phase of the program until the JPO provides full details including an independent cost estimate, final acquisition strategy and test plan. Last year, Vice. Adm. Mat Winter, the F-35's program executive, announced that the JPO would pursue a path of rapid, agile software modernization during Block 4 called continuous capability development and delivery, or C2D2. The thrust behind C2D2 is for the government to constantly be developing, testing and delivering new capabilities as they become available, instead of as part of a traditional batch of upgrades every couple years. Currently, the cost of the new plan is unknown. The Department of Defense plans to update its acquisition strategy in time for a Defense Acquisition Board meeting this month, when it will decide when to start the competition for Block 4 development.

Sign up for our Military Space Report Get the latest news about space and strategic systems Subscribe However, a full business case won't be finalized until March 2019 — despite the fact that the Pentagon has asked for $278 million in fiscal 2019 for Block 4 development. “As a result, DOD requested funding for modernization over a year before the program has a business case for Block 4,” the report stated. “This means that the program is asking Congress to authorize and appropriate funds for Block 4 without insight into its complete cost, schedule, and technical baselines. Furthermore, once Congress appropriates these funds, DOD would be able to award a contract, beginning a long-term commitment to Block 4, the costs of which are not fully understood.” However, the GAO also acknowledged that there are some elements of that plan that could end up being a boon to the DoD. For one, it plans to use “government-owned open systems architecture and acquire data rights” for Block 4 development, which could increase competition throughout the F-35's life cycle and make it easier and cheaper to upgrade the platform. The C2D2 strategy may also “potentially shorten time frames for delivering capabilities over a traditional acquisition approach,” the agency said in the report. Most of the noted flaws in the C2D2 plan revolve around oversight — specifically the DoD's decision to keep Block 4 underneath the F-35 program instead of making it a separate acquisition program. “According to DOD's January 2018 report, however, each capability will be baselined separately in the program's future Block 4 annual reports to Congress,” the GAO noted. “We will review these future reports to Congress to determine what level of insight they provide into the program's cost, schedule, and performance goals.” https://www.defensenews.com/air/2018/06/05/watchdog-group-to-pentagon-fix-f-35-tech-problems-before-full-rate-production-starts/

  Le budget défense 2021 adopté par le Sénat

  Par Le Figaro avec AFP Publié hier à 19:55 Le Sénat a adopté ce jeudi le budget 2021 des Armées, en hausse pour la troisième année consécutive (+4,5% sur un an) à 39,2 milliards d'euros. Ce budget «pour la troisième année consécutive respecte à la lettre les engagements et la trajectoire financière de la loi de programmation militaire» (LPM) 2019-2025, a fait valoir devant les sénateurs la ministre des Armées Florence Parly. «Nous le faisons malgré la crise sanitaire et malgré la crise économique qui prévaut actuellement. Donc c'est à la fois de la continuité, de la confiance par la visibilité donnée et de la relance», a-t-elle affirmé à l'AFP peu avant le vote des sénateurs. Lors du débat, la ministre a été interrogée sur le coût du remplacement de 12 avions Rafale prélevés sur l'inventaire de l'armée de l'Air au profit de la Grèce. Athènes a annoncé mi-septembre son intention d'acquérir six Rafale neufs et douze d'occasion, pour un montant compris «entre un et deux milliards d'euros», selon le cabinet de la ministre. «Les discussions pourraient aboutir d'ici la fin de l'année», selon Florence Parly. «Si ce contrat aboutit, alors le produit de la vente des Rafale d'occasion reviendra bien au ministère des Armées» et non au budget général de l'Etat, a-t-elle déclaré. «Nous avons eu toutes les assurances du ministère de l'Economie et des Finances à ce sujet.» Pour remplacer les 12 avions d'occasion vendus à la Grèce, Paris doit commander en parallèle 12 Rafale neufs pour les besoins de l'armée de l'Air française. Florence Parly a par ailleurs indiqué aux sénateurs que les surcoûts des opérations extérieures (Opex) et intérieures s'élevaient en 2020 à 1,46 milliard d'euros. Ils «sont couverts en 2020 à la fois par la provision constituée en loi de finances initiale (1,1 milliard, NDR), ainsi que par des contributions internationales et des redéploiements internes inférieurs à 60 millions d'euros et enfin par des ouvertures de crédits (...) pour 200 millions d'euros», a-t-elle détaillé. La ministre a toutefois indiqué avoir renoncé à ce dernier financement en raison du «contexte sanitaire» et «par solidarité interministérielle». Sur le milliard d'euros de crédits gelés en début d'année au titre de «réserve de précaution», «800 millions d'euros qui étaient gelés ont été dégelés dès la mi-novembre», a-t-elle plaidé auprès de l'AFP. Le budget 2021 doit faire l'objet d'une adoption définitive par le Parlement au plus tard le 18 décembre. https://www.lefigaro.fr/flash-eco/le-budget-defense-2021-adopte-par-le-senat-20201203
