Space Development Agency wants someone to launch its first 28 satellites
WASHINGTON — Now that the Space Development Agency has selected four contractors to build its first 28 satellites, the organization is looking for a launch provider to ferry them into orbit.
According to a solicitation posted Oct. 6, the agency plans to select one company to provide launch services for all 28 satellites, with the first launch taking place in September 2022.
Those 28 satellites will comprise tranche 0 of SDA's National Defense Space Architecture, a new proliferated constellation providing a whole host of services primarily from low Earth orbit. Among other things, the NDSA is anticipated to provide beyond-line-of-site targeting, hypersonic missile warning and tracking, and a space-based mesh network that will connect all of the services as part of the Pentagon's new Combined Joint All-Domain Command and Control (CJADC2) approach.
The constellation will ultimately include hundreds of satellites, but SDA isn't putting them all up at once. Rather, the agency has adopted a spiral development approach, where the most mature and ready technology is added to the constellation in two year tranches.
This launch solicitation covers the first tranche, otherwise known as tranche 0. Slated to go into orbit in fall 2022, tranche 0 is what SDA calls its “war fighter immersion tranche.”
“Its goal is to provide the data in a format that the war fighters are used to seeing on tactical timelines that they can be expected to see once we actually become operational,” SDA Director Derek Tournear told C4ISRNET. “The whole purpose of tranche 0 is to allow the war fighters to start to train and develop tactics, techniques and procedures so that they can create operational plans for a battle where they would actually incorporate these data.”
With just 28 satellites, tranche 0 will not provide global, persistent coverage. Instead, it will provide periodic, regional capabilities. Tranche 0 will feature the inaugural satellites in the transport and tracking layers. The 20 transport layer satellites will form the base of a space-based mesh network, passing data from satellites to weapon systems along a high-speed, on-orbit corridor. Tournear has previously stated that the transport layer will serve as the space component of CJADC2, the Pentagon's effort to connect sensors to shooters across domains and services.
The inaugural tracking layer will be made up of eight satellites. The tracking layer will be used to detect and track hypersonic threats, working with the transport layer to pass tracking data and custody from satellite to satellite—collaborating to keep an eye on globe-traversing missiles that can evade current missile warning capabilities.
SDA has selected Lockheed Martin and York Space Systems to each build 10 of the transport layer satellites, while SpaceX and L3 Harris will split the eight tracking layer satellites.
Because the SDA has given vendors flexibility in the designs of their satellites, there is some variety to the weight of the space vehicles being launched into orbit. While all 20 transport layer satellites will weigh approximately 200 kilograms, give or take 20 kilograms, there is a significant difference in the size of the eight tracking layer satellites. One vendor—either SpaceX or L3 Harris—will be contributing four tracking layer space vehicles weighing approximately 1,068 kg each. The other vendor's space vehicles will be significantly lighter at just 249 kg.
In total, SDA is looking to put as much as 10,164 kg of hardware into orbit. The agency wants all 28 satellites delivered to two circular, 950 km near-polar orbits, with the tranche divided evenly into two planes of 14 satellites. The launch provider has until March 31, 2023, to put all payloads on orbit and has discretion as to how many launches it will use to do that. The goal is to have as many satellites up as close to September 2022 as possible.
Proposals are due by Nov. 5 at 4 p.m. EST.

KC-46, P-8 production to stop as Boeing temporarily shuts down facilities
By: Valerie Insinna WASHINGTON — Production of the Air Force's KC-46 refueling tanker and the Navy's P-8 maritime surveillance plane will stop as Boeing shuts down all facilities in the Seattle area amid the coronavirus pandemic. “Boeing plans to begin reducing production activity today and projects the suspension of such operations to begin on Wednesday, March 25, at sites across the Puget Sound area,” the company said in a statement on Monday. A Boeing spokesman confirmed that the impacted area includes the facilities in Everett and Renton, where the KC-46 and P-8 are made, respectively. “We plan to temporarily suspend all production operations, including those relating to P-8 and KC-46A, in the Puget Sound region,” the spokesman said. “We're actively engaged with our defense customers to minimize any impacts on their missions. Certain non-production work for all commercial derivative aircraft programs, including for the KC-46 remote vision system enhancements, will continue being done by employees working remotely.” The company is urging employees to telework if they can, but work on classified projects cannot be done on laptops, which could impact more sensitive elements of defense programs. The production stoppage itself is perhaps an even more urgent challenge. Boeing's Puget Sound facilities are best known for commercial airliner production, but the commercial-derivative aircraft it makes for the military —like the KC-46 and P-8 — are built on the same lines. Any pause in commercial production could put Boeing behind in delivering aircraft to the Air Force and Navy. However, Boeing's defense business will likely be able to make a quick recovery as long as the pause in production is not protracted, said Richard Aboulafia, an aerospace analyst with the Teal Group. “P-8, KC-46 and other Boeing defense production in the Puget Sound area is mostly low-volume, like around 1-2 per month,” he said. “So they should be able to recover over the course of the year, assuming the factory deep clean is successful and the pandemic threat turns a corner.” Boeing CEO Dave Calhoun characterized the temporary plant closures as a “necessary step” to protect employees in the wake of a state of emergency in Washington state. "We continue to work closely with public health officials, and we're in contact with our customers, suppliers and other stakeholders who are affected by this temporary suspension,” he said. “We regret the difficulty this will cause them, as well as our employees, but it's vital to maintain health and safety for all those who support our products and services, and to assist in the national effort to combat the spread of COVID-19.” The company will also continue to monitor U.S. government guidance on COVID-19 and conduct a deep cleaning of impacted sites during the two-week pause, Boeing said. https://www.defensenews.com/coronavirus/2020/03/23/kc-46-p-8-production-to-stop-as-boeing-temporarily-shuts-down-production-in-puget-sound-area/
