WASHINGTON - The U.S. Space Force will begin sharing valuable space situational awareness data with the United Kingdom as part of Operation Olympic Defender, the service announced Aug. 14.
Under a recently signed agreement, the Space Force will share it's Standardized Astrodynamics Algorithm Library with the U.K.‘s Ministry of Defense. SAAL is a collection of the Space Force's understanding of orbital physics and algorithms that helps the service predict the trajectories of objects on orbit.
“Aggressive actions in space must be deterred through a multinational, coordinated effort, allowing for the defense and protection or our collective capabilities,” said Maj. Gen. DeAnna Burt, USSF director of Operations and Communications, in a statement. “Sharing the SAAL with our coalition partners enables greater cooperation and coordination between the U.S. and our Allies.”
The agreement comes as part of Operation Olympic Defender, an American-led coalition of space-faring allies working together to deter hostile actions in space, strengthen deterrence against hostile actors and address the growing issue of orbital debris. Operation Olympic Defender was officially taken over by U.S. Space Command in May and is located at the Combined Space Operations Center at Vandenberg Air Force Base, California.
The U.K. was the first nation to join Operation Olympic Defender and is the first to receive access to the SAAL. Under the new arrangement, that nation's Space operations Center will now be better able to collaborate with the Space Force, sharing algorithms and data to better predict orbital trajectories.
The Space Force is looking to share the SAAL with more partners within Operation Olympic Defender. According to the announcement, the Secretary of the Air Force's International Affairs Office, SPACECOM and the Space Force have recognized a new framework that will allow other coalition partners to begin receiving SAAL. SPACECOM has signed a number of space data sharing agreements with other countries in recent months.

Lee Hudson The Pentagon intends to request additional stimulus funding from Congress to support the defense industrial base in the wake of the COVID-19 pandemic, Defense Secretary Mark Esper says. The funding would go to small suppliers that have been hit hard by the spread of the novel coronavirus, Esper said May 4 during a Brookings Institution event. In recent weeks, Congress has passed about $3 trillion in emergency funding bills related to COVID-19. The Senate is in session this week, but the House has postponed votes. It is unknown when the next stimulus package will wrap up. “We anticipate the likely need for additional monies ... because we see again greater demand with regard to medical supplies and equipment,” Esper said. But House Armed Services Committee Chairman Adam Smith (D-Wash.) said the Pentagon should not receive stimulus funding from the Coronavirus Aid, Relief and Economic Security Act because the public health sector needs it more. Last week, Pentagon acquisition executive Ellen Lord said the Pentagon may have wiggle room to use some of its own operations and maintenance funding to pay for COVID-19-related efforts. Lord cautioned that the Pentagon may not have the fiscal flexibility to pay for new demands on the agency to battle COVID-19. “I will say that we continue to look at gaps in funding we have for specific issues. We continue to work with [the Office of Management and Budget] on that, and we will continue to talk to Congress about what we assess as our needs to really carry out our missions,” Lord said. The Defense Department (DOD) wants to continue supporting the defense industry by issuing progress payments to help with cash flow, Esper said. “DOD is not an island. We really rely heavily on the private sector, and so many of our private sector workforce has been affected by COVID-19,” Esper said. Some defense contractor personnel are infected with the virus, while others are working in states with shutdown orders and management does not want them coming into work because of tight quarters, he said. Separately, Esper is concerned the nation's additional debt incurred due to COVID-19 may result in smaller defense budgets during a critical time when China and Russia are strategic competitors of the U.S. The U.S. must recapitalize the nuclear triad and invest in hypersonic weapons, artificial intelligence, space capabilities and directed energy, Esper said. https://aviationweek.com/defense-space/budget-policy-operations/dod-seeking-more-covid-19-stimulus-funding-esper-says

Over the last five years Rolls-Royce has been pioneering world-first technology that will contribute to the UK's next-generation Tempest programme. In an aim to be more electric, more intelligent and to harness more power, Rolls-Royce recognised that any future fighter aircraft will have unprecedented levels of electrical power demand and thermal load; all needing to be managed within the context of a stealthy aircraft. Before the launch of the Tempest programme, Rolls-Royce had already started to address the demands of the future. Back in 2014, the company took on the challenge of designing an electrical starter generator that was fully embedded in the core of a gas turbine engine, now known as the Embedded Electrical Starter Generator or E2SG demonstrator programme. Conrad Banks, Chief Engineer for Future Programmes at Rolls-Royce said: "The electrical embedded starter-generator will save space and provide the large amount of electrical power required by future fighters. Existing aircraft engines generate power through a gearbox underneath the engine, which drives a generator. In addition to adding moving parts and complexity, the space required outside the engine for the gearbox and generator makes the airframe larger, which is undesirable in a stealthy platform." Phase two of this programme has now been adopted as part of Rolls-Royce's contribution to the Tempest programme. As part of this journey, the company has been continuously developing its capabilities in the aerospace market, from gas turbine technologies through to integrated power and propulsion systems. The goal being to provide not only the thrust that propels an aircraft through the sky, but also the electrical power required for all the systems on board as well as managing all the resulting thermal loads. Rolls-Royce is adapting to the reality that all future vehicles, whether on land, in the air or at sea will have significantly increased levels of electrification to power sensors, communications systems weapons, actuation systems and accessories, as well as the usual array of avionics. The launch of phase one of the E2SG programme saw significant investment in the development of an integrated electrical facility – a unique test house where gas turbine engines can be physically connected to a DC electrical network. The launch of the second phase of the project in 2017 saw the inclusion of a second electrical generator connected to the other spool of the engine. It also included an energy storage system in the electrical network and the ability to intelligently manage the supply of power between all these systems. The two-spool mounted electrical machines allows, by combination of operation as either a motor or a generator, the production of a series of functional effects on the engine, including the transfer of power electrically between the two spools. As part of the E2SG programme, Rolls-Royce is investigating the feasibility of using dual spool generation to influence the operability, responsiveness and efficiency of the engine. Another key technology under development is the Power Manager intelligent control system, which uses algorithms to make real time intelligent decisions about how to supply the current aircraft electrical demand while optimising other factors including engine efficiency to reduce fuel burn or engine temperature to extend component life. Throughout the Tempest programme, Rolls-Royce will be continuing to mature the electrical technologies demonstrated by the E2SG programme, with a third phase of testing likely to include a novel thermal management system being integrated with the overall system, as well as more electric engine accessories. The company also intends to showcase a full-scale demonstrator of an advanced power and propulsion system. There will be new technologies in all parts of the gas turbine, including twin spool embedded generation to higher power levels, an advanced thermal management system, an energy storage system tailored to the expected duty cycle of the future fighter and an intelligent power management system which will be able to optimise the performance of both the gas turbine and the power and thermal management system.
