“We stood up our high-rate manufacturing facility, Victory Works, to meet the demanding requirements of our customer,” said Erik Daehler, Senior Vice President of Sierra Space Defense. “To go from a successful Critical Design Review to completing the Plane 1 satellite structures—three months ahead of schedule—is a powerful validation of our investment in scalable infrastructure. Our team is energized as we move into the next phase of Plane 1 development, focusing on assembly, integration, and testing, while also beginning the satellite structure build for Plane 2, the remaining nine satellites of the 18-satellite constellation for SDA.”
The next stage currently planned for Plane 1 is a transition to the assembly, integration, and testing (AI&T) phase, during which components, subsystems, and payloads are expected to be integrated and subjected to rigorous testing to verify performance and readiness for deployment.
“As we move closer to delivering this capability, every phase of development is essential to ensuring mission success,” added Daehler. “We believe the Tranche 2 Tracking Layer will provide unmatched missile tracking capabilities for SDA and its mission partners, and we remain committed to meeting each milestone with precision and speed.”
Building on this momentum, Sierra Space is also preparing to expand its capabilities to meet future demands for advanced fire-control and missile defense tracking systems.
“This mission is too important to not be continuously evolving,” said John Wagner, Sierra Space Vice President of Strategy and Business Development. “We are scaling our production capabilities and advancing our detection technologies, including the next generation of fire-control missile defense sensors. We believe our infrastructure, expertise, and track record position us to support the Department of War’s evolving needs for advanced tracking and missile defense.”
Sierra Space is contracted to deliver two orbital planes of satellites—18 in total—equipped with advanced infrared sensors to detect and track ballistic, hypersonic, and next-generation missile threats.
Sierra Space’s progress highlights its ability to combine commercial agility with deep defense expertise, delivering advanced solutions that meet the Department of War’s priorities. With over 30 years of spaceflight heritage and a track record of supporting more than 500 missions, Sierra Space continues to lead the way in building resilient mission systems for national security and allied partners.
About Tranche 2
The Tranche 2 Tracking Layer’s 54 satellites will build upon the Tranche 1 Tracking Layer capabilities with a select number of satellite vehicles that will incorporate fire control missile defense infrared sensors that can generate fire control quality tracks to provide preliminary missile defense mission capabilities in support of warfighter missions around the globe.
The Tracking Layer is focused on delivering a global constellation of infrared missile warning and missile tracking satellites that integrate with the Transport Layer’s low-latency meshed communication network, enabling advanced missile tracking from proliferated low-Earth orbit. Once completely fielded, the Tranche 2 constellation will consist of approximately 270 operational Transport and Tracking Layer satellites.

MINNEAPOLIS (AP) — A federal officer shot and killed a Minneapolis motorist when she allegedly tried to run over law enforcement officers during an immigration crackdown in the city, authorities said Wednesday.
The Immigration and Customs Enforcement officer shot the woman in her vehicle in a residential neighborhood in Minneapolis, Department of Homeland Security spokeswoman Tricia McLaughlin said in a statement.
The shooting marks a dramatic escalation of the latest in a series of immigration enforcement operations in major American cities under the Trump administration. It's at least the fifth person killed in a handful of states since 2024.
The twin cities of Minneapolis and St. Paul have been on edge since DHS announced Tuesday that it had launched the operation, with more than 2,000 agents and officers expected to participate in the crackdown tied in part to allegations of fraud involving Somali residents.
A large throng of protesters gathered at the scene after the shooting, where they vented their anger at the local and federal officers who were there, including Gregory Bovino, a senior U.S. Customs and Border Patrol official who has been the face of crackdowns in Los Angeles, Chicago and elsewhere.
In a scene that hearkened back to the Los Angeles and Chicago crackdowns, bystanders heckled the officers and blew whistles that have become ubiquitous during the operations.
“Shame! Shame! Shame!” and “ICE out of Minnesota!” they loudly chanted from behind the police tape.
After the shooting, Mayor Jacob Frey said immigration agents were “causing chaos in our city.”
“We are demanding ICE leave the city and state immediately. We stand rock solid with our immigrant and refugee communities," Frey said on social media.
The area where the shooting occurred is a modest neighborhood south of downtown Minneapolis, just a few blocks from some of the oldest immigrant markets in the area and a mile (1.6 kilometers) from where George Floyd was killed by police in 2020.
“We’ve been trying to live life as fully as possible in light of the fear and anxiety that we feel,” said the Rev. Hierald Osorto, pastor at St. Paul’s-San Pablo Lutheran Church, which has a predominantly Latino congregation in the area.
During a news conference in Texas on Wednesday, DHS Secretary Kristi Noem confirmed that the agency had deployed more than 2,000 officers to the Twin Cities and already made “hundreds and hundreds” of arrests.
For nearly a year, migrant rights advocates and neighborhood activists across the Twin Cities have been preparing to mobilize in the event of an immigration enforcement surge. From houses of worship to mobile home parks, they have set up very active online networks, scanned license plates for possible federal vehicles and bought whistles and other noise-making devices to alert neighborhoods of any enforcement presence.
On Tuesday night, the Immigration Defense Network, a coalition of groups serving immigrants in Minnesota, held a training session for about 100 people who were willing to hit the streets to monitor the federal enforcement operation.
“I feel like I'm an ordinary person, and I have the ability do something so I need to do it,” Mary Moran told KMSP-TV.
