Space Development Agency Makes Awards to Build 72 Tracking Layer Satellites for Tranche 3
Just wrote about this yesterday and was going to create a full post about the L3Harris/Maxar/Lanteris connection, probably not necessary anymore: https://www.reddit.com/r/IntuitiveMachines/s/xjwbjAzkWP Still believe the market has yet to digest the Lanteris acquisition properly. It's in my opinion equivalent to RKLB l's space systems size, if not bigger, which represents 75% of RKLB business. RKLB is a $35 billion company now, they have top notch management and have a great launch service but that's only 25% of their business and a huge drag on profitability but if the market is willing to assign them a price-to-sales ratio close to 50 and though very rich, it's 10 times higher than LUNR multiples. I can understand if it's just another ho-hum company but this is space and space exploration will take center stage over the next few years, especially in light of this administration's renewed focus on the moon, building infrastructure and outposts.

June 1, 2025Lukas C. H. on Twitter: We have just gotten the first image of the semi-classified SDA Tranche 0 Flight 1 payload stack! This also gives us a look at the SpaceX Starshield-based Tracking Layer satellites, which are the 2 satellites on top. The other satellites are York's Transport Layer satellites.
I understand each of those words individually, but not in that order. Can someone kindly explain what this is and why it is interesting? More on reddit.com
