I have been looking forward to talking about Project Shadow publicly for months. Since the beginning of 2025, our Special Projects team (led by all-star Charlie Horowitz) has been working hard to piece together the key technologies required to not only make Space Based Interceptors work-- but to manufacture them at the scale needed to defend the United States, our allies, and democracy globally.
Today, we unveil Project Shadow — Apex's on-orbit Space-Based Interceptor (SBI) technology demonstration, launching NET June 2026. At Apex, we often launch self-funded missions to advance our technology and demonstrate our capabilities in space. Over 1.5 years ago, we launched our first Aries satellite, which continues to serve as an on-orbit software testbed for our team and customers. Project Shadow is our next step internally funded mission (with more to come in the future). Launching on our Nova satellite bus platform, Shadow integrates and demonstrates key SBI technologies in a single, end-to-end mission. Here’s an inside look at Shadow: 1. Apex’s Nova platform will be outfitted with the “Orbital Magazine” configuration package, providing environmental management for the demonstration interceptors, a Link-182–compatible radio, and Missile Warning/Tracking sensors. 2. The Orbital Magazine will carry two scaled-down demonstration interceptors, each equipped with a solid rocket motor (SRM) and a suite of data-collection sensors. 3. The Orbital Magazine will launch NET June 2026, and after LEOPS and commissioning, Apex will issue a fire control command. 4. The Orbital Magazine will deploy the first interceptor and establish an inter-satellite link. The interceptor will be tasked to fire its SRM while oriented in the inverse velocity direction, avoiding other in-space objects, and safely deorbiting after the burn. 5. During the burn, the Missile Warning/Tracking payloads on the Orbital Magazine will gather critical data on on-orbit SRM performance, determine tracks, and more. 6. The second interceptor will be deployed shortly after, establish a crosslink, and receive a command to fire its SRM, following a similar trajectory to the first demonstration interceptor and safely deorbiting. Project Shadow is self-funded by Apex. We believe that supporting America, our allies, and democracy requires direct investment in the development and maturation of key defense technologies — including SBIs.

The Quickfish has been operating on water since May, but we intentionally delayed the public unveiling until now. We used those months to build up performance data and continue iterating on the product so we live up to the #RealDeal standard that Seasats' brand is built on. Quickfish delivers: 1️⃣ High speed intercept and interdiction 2️⃣ Long at sea loiter times -- because bad actors don't always show up when you think they will 3️⃣ Aerial vehicle integration -- a concealed internal bay maximizes deterrence on every vessel Our international partners are on board with deals signed in the Philippines, Australia, and Japan. Stay tuned for more. Article in comments. #ASVs #Autonomy #DefenseTech #MaritimeSecurity #BlueTech

Welcome Quickfish to the Seasats family of USV's! With multi-week loiter endurance, a UAV launch bay, and a hull designed for manufacturing at scale, the Quickfish expands Seasats’ mission from persistent sensing to rapid response — empowering defense and research partners alike. Learn more about how Seasats is redefining maritime autonomy at https://seasats.com/ #MissionMatters #Autonomy
Introducing the Quickfish, our new high-speed, long-endurance ASV. It's already been proven in a multi-day U.S. Navy exercise, where the Quickfish reached speeds over 35 knots while demonstrating reliable performance, payload modularity, and intuitive autonomy interfaces. With multi-week loiter endurance, a UAV launch bay, and a hull designed for manufacturing at scale, the Quickfish expands Seasats’ mission from persistent sensing to rapid response — empowering defense and research partners alike. As CEO Mike Flanigan puts it: “Our customers love how Lightfish USVs provide multi-month sensing capabilities, but they still need to respond to potential threats with manned assets. Building the Quickfish to provide an intercept capability was a natural extension.” Learn more about how Seasats is redefining maritime autonomy: link in comments. #Seasats #Autonomy #ASV #DefenseInnovation #MaritimeSecurity

Congratulations to the Apex - Spacecraft Manufacturing team on the grand opening of Factory One! This effort is a major milestone for U.S. space manufacturing capacity and will help to accelerate America’s lead in space. In just three years, Apex has grown from a bold idea into a company capable of producing more than 200 satellites per year, breaking through production bottlenecks. It was amazing to see co-founders Ian Cinnamon and Maximilian Benassi Benassi, along with Federal Communications Commission Chairman Brendan Carr, officially open this world-class facility in Los Angeles. This is a testament to how technology at speed and scale can converge to advance both commercial opportunity and national capability. #MissionMatters #space
Thank you to everyone who joined us today for the official grand opening of Factory One! Factory One represents a significant step change in American satellite manufacturing, eliminating the satellite production bottleneck and unlocking critical production capacity for Western governments and key commercial companies to maintain a lead in the New Space Race. With a maximum annual production capacity of over 200 satellites per year, Factory One is rapidly scaling production of Apex’s productized satellite platforms — Aries, Nova, and Comet. Our co-founders, Ian Cinnamon and Maximilian Benassi, had the honor of cutting the ribbon alongside Federal Communications Commission Chairman Brendan Carr, who shared his remarks on how the FCC plans to further accelerate American space innovation — and unleash a new wave of progress across the U.S. space industrial base. See the link in the comments to hear the full remarks from Ian Cinnamon and Chairman Carr!

Save the date! Join our upcoming webinar and learn about the limits of DIY data processing👇 https://lnkd.in/e89xPyP8
DIY data processing solutions work — until their maintenance costs eclipse their value. We’re proud that thousands of teams run production systems on Unstructured OSS. That’s why we open-sourced it in the first place. Over the years, we’ve seen a clear pattern emerge. Teams start strong with DIY pipelines built on OSS: prototypes succeed, workflows get automated, and RAG pipelines begin powering real applications. But as usage grows — more documents, more complexity, more enterprise requirements — maintaining these systems quietly become many full-time jobs. Teams find themselves spending cycles on orchestration, retries, scaling, and troubleshooting, rather than building the features that differentiate their product. From helping hundreds of customers navigate this transition, one lesson stands out: knowing when to consider managed infrastructure isn’t about whether OSS works — it’s about recognizing when your engineering effort could be better spent elsewhere. Managed infrastructure allows teams to focus on delivering value while still benefiting from the base capabilities OSS provides, with the added advantage of continuous improvements, advanced parsing, extensive metadata enrichment features, and more, all handled by a team of experts. In our upcoming webinar, we’ll share these signals and lessons in more detail, helping you decide when it’s time to move from OSS to the Unstructured ETL+ platform: When to Move from Open Source to the Unstructured ETL+ Platform https://lnkd.in/gwwqkXFM
