Very big deal
We announced an agreement to acquire a nationwide low-band spectrum license portfolio that will pave the way for @Starlink to become a major mobile carrier in the US. With this new spectrum and our Gen2 constellation, Starlink Mobile can ensure Americans have access to high-speed mobile broadband no matter where they are → spacex.com/updates#starlink-…

Each @SpaceX Star Mind super intelligence spacecraft will have over 250kW of solar power, which is about 20% more than the International Space Station
The scale of SpaceX satellites is getting absolutely insane Each generation roughly doubles or more in deployed size Starlink V1.5: ~11 m V2 Mini: ~30 m V3: ~60 m AI1: ~75 m wingspan - first-generation orbital AI compute satellite

Fusion energy is often discussed as a matter of plasma physics, funding, and machine design, but bringing commercial fusion to the grid also requires a global industrial base that can manufacture critical components at scale. Today CFS took an important step toward meeting that need, announcing an agreement to purchase more than 10,000 km (3 GA-m) of high-temperature superconducting (HTS) tape from Fujikura Ltd. It’s the largest single purchase order for HTS tape, a critical component of our breakthrough magnets. This news is important evidence that our fusion industrial supply chain is taking shape. Our order allows Fujikura to invest in new manufacturing capacity for the long term, stepping up in our global network of more than 1,000 suppliers across 30 countries. We already built a supply chain for our SPARC fusion demonstration machine, but this agreement helps secure HTS tape for our next chapter: building ARC power plants, starting with our first at the Fall Line Fusion Power Station in Virginia. The ARC effort is moving ahead with design, technology development, and commercialization work like applying to connect that first ARC plant to the grid with PJM Interconnection, the largest U.S. wholesale electricity market.

We have successfully completed a sheltered-water autonomous towing demonstration for @DARPA’s Pulling Guard program. In under six months, our team moved from selection for the program to designing, building, and testing a new vessel created for this effort. During the demonstration, the uncrewed vessel autonomously executed every phase of the towing concept of operations, from station-keeping and connection through towing transit and a controlled disconnect. Every planned test objective was met, including proving that autonomous winch control could be fully integrated with Saronic’s existing autonomy stack and operate as a single coordinated system throughout the sequence. Pulling Guard aims to develop flexible, semi-autonomous surface vessel systems that can escort and help protect unarmed logistics vessels at sea. Reliable autonomous towing and station-keeping are foundational to that concept, and proving these capabilities early reduces technical risk and generates real-world data that will inform the platform’s design and development as the program advances. We are proud to continue working with DARPA to move that concept closer to reality.

Bringing autonomy to the next fight: wildfires. Anduril has earned first place in the Autonomous Wildfire Response Track within the @xprize competition. Our solution manages the entire wildfire lifecycle with minimal human intervention. Lattice coordinates assets across air, land, and space to detect and respond faster. The award reflects Anduril's deep experience building firefighting tech including more than two years of dedicated work with XPRIZE. During the rigorous finals test in the Alaskan wilderness, our platform autonomously detected, fought, and suppressed live fires. Destructive wildfires are a global crisis. Anduril and XPRIZE are pioneering faster, more scalable and more automated ways to fight them.

Important work by @GoodfireAI to help reduce reward hacking in models — reach out if you’re interested to learn more.
we've just had a huge leap in detecting reward hacking in real time with an activation monitor. next up is figuring out how to mitigate it before it happens. one of the most compelling parts of this work is that our activation monitors catch models when they're contemplating a reward hack before it even happens, and can flag reward hacks that external judges miss.

Proud of the @Saronic team and the work behind this award. We're building Port Alpha to bring American shipbuilding back with speed and scale. This award is a real step forward in delivering for today’s fleet while building the hybrid fleet of tomorrow.
We’re excited to announce that Saronic has been awarded a U.S. Navy contract to build Landing Craft Utility (LCU) vessels at Port Alpha, our next-generation shipyard in Brownsville, Texas. Capable of transporting troops, vehicles, and up to 170 tons of cargo directly to beaches and unimproved shorelines, LCUs are essential to amphibious operations, resupply, and disaster-response missions. As Port Alpha’s first build, this program marks an important step toward expanding America’s maritime industrial capacity. It also advances our mission to deliver the vessels the Navy needs today while building toward an autonomous maritime future. Production is expected to begin in 2028, with initial deliveries planned for 2029. Read the full announcement: medium.com/saronic-technolog…
