Northrop Grumman Wins $764M Contract for SDA Tracking Layer Tranche 3 Satellites
Northrop Grumman awarded $764M contract to produce 18 satellites for SDA’s Tracking Layer Tranche 3, enhancing U.S. missile tracking capabilities by 2029.
Northrop Grumman Corporation (NYSE: NOC) has been selected by the Space-Agencies (SDA) to produce and deploy 18 satellites for the Tracking Layer Tranche 3 (TRKT3) mission. Announced on December 19, 2025, the contract is valued at approximately $764 million and represents a significant step forward in the United States’ efforts to modernize its missile defense architecture.
The agreement tasks Northrop Grumman with delivering 18 space vehicles equipped with advanced infrared sensors. These satellites are designed to detect, warn, and track modern missile threats, including highly maneuverable hypersonic glide vehicles. The satellites are scheduled for launch in Fiscal Year 2029 and will form a crucial part of the Proliferated Warfighter Space Architecture (PWSA), a low-Earth orbit (LEO) constellation intended to provide global, persistent surveillance.
According to the company’s official statement, this award cements Northrop Grumman’s role as a primary partner in the PWSA, bringing their total number of contracted satellites across Tranches 1, 2, and 3 to 150.
The Tracking Layer Tranche 3 mission is focused on expanding the “eyes” of the PWSA. Unlike traditional missile warning systems that rely on a small number of high-altitude satellites, the SDA’s strategy utilizes a proliferated network of hundreds of smaller satellites in LEO. This approach aims to provide redundancy and the ability to track threats from launch to impact.
Under the terms of the Other Transaction Authority agreement, Northrop Grumman will Manufacturing the satellites at a dedicated 30,000-square-foot facility designed specifically for the PWSA program. The primary technical objective is to provide “fire-control quality data”, high-precision tracking information that can be relayed directly to interceptors to neutralize incoming threats.
In a press release regarding the selection, Northrop Grumman emphasized the continuity of their technology stack, which leverages Overhead Persistent Infrared (OPIR) capabilities. Brandon White, Vice President and General Manager of Northrop Grumman’s Space-Enabled Multi-Domain Operations Division, highlighted the company’s readiness:
“Our extensive background in both high and low-altitude missile warning systems positions us uniquely to deliver TRKT3 swiftly, reinforcing the nation’s defense framework against a diversifying array of threats.”
— Brandon White, Northrop Grumman (via Press Release)
The SDA’s procurement strategy for Tranche 3 involves a total funding pool of approximately $3.5 billion, distributed among four distinct vendors to build a total of 72 satellites. This multi-vendor approach is designed to foster competition, reduce costs, and ensure supply chain resilience.
According to public award data released by the SDA, Northrop Grumman is joined by three other prime contractors in this tranche:
While all four companies are delivering tracking capabilities, the specific sensor requirements vary slightly between vendors. Northrop Grumman’s specific allocation is for the Missile Warning/Missile Tracking (MW/MT) variant, which focuses on detecting launches and tracking flight paths to support the broader network.
The selection of four distinct vendors for Tranche 3 underscores the Space Development Agency’s commitment to a “proliferated” industrial base as well as a proliferated satellite constellation. By avoiding reliance on a single prime contractor, the SDA mitigates the risk of program delays caused by supply chain bottlenecks at any one company.
Furthermore, the inclusion of Rocket Lab alongside traditional defense giants like Northrop Grumman and Lockheed Martin signals a maturing of the space defense market, where “New Space” agility is increasingly integrated with established defense manufacturing capabilities. For Northrop Grumman, securing 18 satellites in this tranche, bringing their program total to 150, validates their investment in scalable satellite manufacturing facilities tailored to the SDA’s rapid two-year launch cadence.
The TRKT3 satellites will not operate in isolation. They are designed to integrate seamlessly with the PWSA’s “Transport Layer,” a mesh network of communication satellites that serves as the backbone for data transfer. This integration ensures that the tracking data generated by Northrop Grumman’s sensors can be transmitted with low latency to ground forces and weapon systems.
The company noted that the Tranche 3 satellites will feature “targeted technological improvements” over previous generations, including expanded geographical coverage and enhanced systems integration. With a target launch date in Fiscal Year 2029, these systems represent the next evolution in the U.S. Space Force’s ability to counter hypersonic threats that fly faster than five times the speed of sound.

Sodern Opens First US Facility in Colorado for Star Tracker Production
Sodern launches its first US industrial subsidiary in Colorado, producing Auriga™ star trackers and expanding in the US aerospace market.
This article is based on an official press release from Sodern.
Sodern, a prominent French manufacturer of space equipment and a subsidiary of ArianeGroup, has officially inaugurated its first United States industrial subsidiary, Sodern America. Located in Englewood, Colorado, the new facility marks a significant strategic expansion for the European aerospace giant, representing ArianeGroup’s first industrial installation on American soil.
According to the company’s announcement, the opening of Sodern America is designed to bring the manufacturer closer to its U.S. client base and navigate domestic regulatory requirements. The move positions Sodern to compete directly with established American firms in the defense and commercial space sectors by establishing a local supply chain and production capability.
The new subsidiary is situated in the Denver metropolitan area, a region widely recognized as a major hub for the U.S. aerospace industry. The facility spans approximately 14,000 square feet (1,300 square meters) and is equipped to handle manufacturing, testing, and commercial support.
In its official statement, Sodern outlined the specific operational capabilities of the Englewood site:
By establishing this physical presence, Sodern aims to address the “dynamic and demanding” nature of the U.S. market, ensuring that critical components are available with shorter supply-chains than those requiring import from Europe.
To lead the new subsidiary, Sodern has appointed Tiphaine Louradour as the CEO of Sodern America. Louradour brings over 25 years of experience in the space industry, having held significant leadership roles at major U.S. aerospace organizations.
According to biographical details released in conjunction with the announcement, Louradour’s background includes serving as CEO of Spaceflight Inc., President of International Launch Services (ILS), and President of Global Commercial Sales at United Launch Alliance (ULA). Her appointment signals Sodern’s intent to leverage deep ties within the U.S. space industrial base to secure new contracts.
A primary driver for this expansion, as noted in the company’s strategic rationale, is compliance with U.S. regulatory frameworks. Foreign entities often face barriers when bidding for U.S. government defense and civil space contracts due to strict domestic content requirements, often referred to as “Buy American” mandates. By manufacturing the Auriga™ star tracker and conducting testing in Colorado, Sodern America intends to qualify for sensitive programs that are typically restricted to U.S. entities. This local status allows the company to bypass previous regulatory hurdles and compete on equal footing with domestic manufacturers.
The entry of Sodern America into the Colorado aerospace cluster places it in direct proximity to some of its fiercest competitors. The Denver area is home to Blue Canyon Technologies (a subsidiary of RTX), which is a market leader in small satellite components and star trackers. Additionally, Ball Aerospace (now part of BAE Systems Space & Mission Systems) and Honeywell Aerospace maintain significant operations in the region.
Sodern is already a supplier for major U.S. stakeholders, including NASA, providing instruments for the InSight Mars mission and the Europa Clipper, and the OneWeb constellation. However, establishing a manufacturing foothold suggests a shift from being an exporter to becoming an embedded part of the U.S. supply chain. This move is likely to intensify competition in the optical sensors market, particularly as satellite constellations continue to scale.

Isar Aerospace Opens Acceptance Test Facility at Esrange Space Center
Isar Aerospace launches a new test site at Esrange, Sweden, to support industrial-scale production of Spectrum rocket ahead of March 2026 flight.
This article is based on an official press release from Isar Aerospace.
Isar Aerospace has officially inaugurated a new acceptance test facility at the Esrange Space Center in Kiruna, Sweden. Announced on February 4, 2026, the opening marks a significant transition for the Munich-based launch provider as it shifts focus from prototype development to the industrial-scale production of its Spectrum launch vehicle.
The new site is purpose-built to verify the flight readiness of manufactured hardware, a critical step in ensuring high-cadence Launch operations. According to the company, the facility is designed to test over 30 Aquila engines per month, alongside fully integrated rocket stages. This infrastructure expansion comes just weeks before Isar Aerospace attempts its second Test-Flights, mission “Onward and Upward,” scheduled to First-Flight from Andøya Spaceport in Norway in March 2026.
Unlike development testing, which focuses on validating design concepts, acceptance testing is the final quality control step before hardware is shipped to the launch pad. Isar Aerospace stated in their press release that the new facility is specifically engineered to remove production bottlenecks. By securing dedicated infrastructure for acceptance testing, the company aims to ensure that every engine and stage coming off the assembly line is immediately qualified for flight.
The facility operates alongside Isar’s existing vertical test stand (VTS-2) at Esrange, which has been utilized for development testing since 2019. The addition of the new site allows for parallel operations: R&D can continue on the vertical stand while the new facility handles the volume required for serial production.
“Scaling reliable access to space requires not only advanced launch vehicle design but also the right infrastructure to support rapid development and production. With our second test facility at Esrange, we are unlocking new capabilities and accelerating our progress.”
, Daniel Metzler, CEO & Co-Founder, Isar Aerospace
The new infrastructure significantly increases the company’s throughput. Isar Aerospace reports that the site is equipped to handle the acceptance testing of more than 30 Aquila engines monthly. Furthermore, the site supports integrated stage testing, allowing engineers to verify the entire rocket stage as a cohesive unit before it leaves Sweden.
The opening of this facility highlights the intensifying race among European launch Startups to provide sovereign access to space. Isar Aerospace is competing with peers such as Rocket Factory Augsburg (RFA) and Orbex to fill the gap in Europe’s launch market. By vertically integrating its testing capabilities, Isar Aerospace reduces reliance on shared facilities, potentially giving it an advantage in scheduling and launch cadence. Swedish Space Corporation (SSC), which operates Esrange, emphasized the importance of this Partnerships for the broader European ecosystem.
“This new facility strengthens Europe’s path toward scalable and reliable access to space… Together, we are building the infrastructure that will enable a new generation of launch services.”
, Mats Tyni, Director of Business Development, SSC
The distinction between “development” and “acceptance” testing is often overlooked, yet it is the primary hurdle for launch companies moving from a single successful flight to a commercial service. In our view, Isar Aerospace’s Investments in a high-volume acceptance facility signals confidence in their hardware design. It suggests the company believes the Aquila engine design is mature enough to freeze for mass production. If the upcoming March 2026 flight is successful, this infrastructure will be the key enabler that allows them to fulfill their backlog without the testing bottlenecks that have historically plagued the industry.
The facility inauguration serves as a prelude to Isar Aerospace’s next major milestone. The company confirmed that its second test flight, dubbed “Onward and Upward,” is targeted for a launch window in March 2026. This mission will utilize the Spectrum vehicle, a two-stage rocket designed to carry up to 1,000 kg to Low Earth Orbit (LEO).
The Spectrum vehicle relies on the Aquila engines tested at Esrange, which utilize Liquid Oxygen (LOX) and Propane. Following a flight termination during the first test launch in March 2025, the company has conducted extensive hot-fire tests to validate system corrections. The new acceptance facility will likely play a central role in qualifying engines for vehicles 3 through 7, which are currently planned for concurrent production.

SpaceX Crew-12 Arrives in Florida for February ISS Launch
Crew-12 astronauts from NASA, ESA, and Roscosmos arrive at Kennedy Space Center ahead of their February 11 launch to the ISS aboard SpaceX Crew Dragon.
This article is based on an official press release from NASA and additional mission data from ESA and Roscosmos.
The four-member crew of the SpaceX Crew-12 mission arrived at the Kennedy Space Center (KSC) in Florida on Friday, February 6, 2026, marking the final operational milestone before their scheduled Launch to the International Space Station (ISS). Flying in from the Johnson Space Center in Houston, the international team of astronauts landed at the Launch and Landing Facility to commence final preparations and mandatory quarantine protocols.
According to NASA, the mission is targeted to lift off on Wednesday, February 11, 2026, at 6:01 a.m. EST. The crew will ride aboard the SpaceX Crew Dragon spacecraft named Freedom, propelled by a Falcon 9 rocket from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station. This flight represents a continuation of the Commercial Crew Program’s efforts to maintain a continuous human presence in low-Earth orbit.
The arrival of Crew-12 is operationally critical for the ISS, which has recently functioned with a reduced staff due to schedule shifts and medical evaluations. The successful docking of Crew-12, targeted for approximately 10:30 a.m. EST on February 12, will restore the orbiting laboratory to its full complement of seven astronauts, stabilizing maintenance rosters and scientific output for Expeditions 74 and 75.
The Crew-12 mission brings together representatives from three major Space-Agencies: NASA, the European Space Agency (ESA), and Roscosmos. The mission duration is expected to last approximately nine months, during which the crew will conduct hundreds of scientific experiments and technology demonstrations.
In an official statement regarding the mission’s scope, NASA noted:
“Crew-12 will conduct scientific investigations and technology demonstrations to help prepare humans for future exploration missions to the Moon and Mars, as well as benefit people on Earth.”
Following the launch on February 11, the crew will execute a 28-hour rendezvous profile before docking with the ISS. Once aboard, they will overlap briefly with the departing crew before settling into a long-duration stay focused on deep space biology, material science, and Earth observation.
The manifest for Crew-12 features a blend of veteran leadership and rookie talent, including two American astronauts, one French astronaut, and one Russian cosmonaut. Leading the mission is veteran astronaut Jessica Meir. Meir previously served on Expedition 61/62 in 2019 and 2020, where she gained global recognition for participating in the first all-female spacewalk alongside Christina Koch. A dual American-Swedish citizen, Meir holds a Doctorate in Marine Biology from the Scripps Institution of Oceanography. Her scientific background includes extensive research on animal physiology in extreme environments, such as emperor penguins in Antarctica. As Mission Commander, she is responsible for all phases of flight, from launch to re-entry.
Seated alongside Meir is mission pilot Jack Hathaway, making his first trip to space. Selected as a NASA astronaut candidate in 2021, Hathaway brings extensive aviation experience as a Commander in the U.S. Navy. He is a distinguished graduate of the Empire Test Pilots’ School and has logged over 2,500 flight hours in more than 30 types of aircraft. His role on Crew-12 involves monitoring vehicle systems and performance during the dynamic phases of flight.
Representing the European Space Agency is Mission Specialist Sophie Adenot. A Lieutenant Colonel in the French Air and Space Force and a helicopter test pilot, Adenot was selected as an ESA astronaut in 2022. She becomes the second French woman to fly to space, following Claudie Haigneré’s mission in 1996. Adenot’s individual mission is designated “Epsilon.”
Commenting on the significance of her role, Adenot stated:
“With this Epsilon mission, France and Europe are contributing to a global endeavor. Space exploration connects science, economy, technology, education, and diplomacy.”
Rounding out the crew is Roscosmos cosmonaut Andrey Fedyaev. This flight marks his second journey to the ISS, having previously flown on the SpaceX Crew-6 mission from March to September 2023. Fedyaev’s inclusion in the crew is notable for making him the first Russian cosmonaut to fly twice on a SpaceX Dragon vehicle. He is tasked with monitoring launch and re-entry phases and managing cargo operations aboard the station.
Upon their arrival in Florida, the crew immediately entered the Neil A. Armstrong Operations and Checkout Building to begin the standard pre-flight quarantine. This health stabilization protocol, a legacy of the Apollo era, is designed to ensure that no viral or bacterial illnesses are transported to the closed environment of the ISS.
The composition of Crew-12 underwent a significant adjustment late in the training flow. In December 2025, Roscosmos cosmonaut Oleg Artemyev was removed from the manifest and replaced by Andrey Fedyaev. While Roscosmos officially cited a “transition to other work” as the reason for the swap, industry reports have suggested the change may have been influenced by internal Regulations. Fedyaev’s previous experience on the Crew-6 mission allowed him to step into the role with a compressed training timeline, ensuring the mission schedule remained on track.
The integration of Andrey Fedyaev into Crew-12 highlights the increasing maturity and interoperability of the Commercial Crew Program. In previous eras of spaceflight, a crew change less than three months before launch could have resulted in significant delays. However, the standardization of the SpaceX Crew Dragon platform allows veteran flyers like Fedyaev to retain currency and step into rotation with reduced lead time. Furthermore, the launch of Crew-12 is pivotal for ISS operations. The station has faced a period of flux regarding crew numbers, and the return to a seven-person staff is essential for clearing the backlog of maintenance tasks and maximizing the scientific return of the orbiting laboratory before the transition to commercial space stations begins later in the decade.
