Part of the SDA's proliferated missile warning demonstration constellation, launched alongside its WILDFIRE siblings in September 2023. The complete Tranche 0 constellation reached 27 satellites total — 19 optically-linked data transport spacecraft and 8 wide-field-of-view tracking satellites like this one — establishing the baseline architecture the SDA expects to scale into a constellation of over 1,000 satellites by 2026.
