SDA "Golden Dome" tracking-layer awards are a confirmed, multi-cycle desk gap.
As the brief logged it
On 2026-07-14 the Space Development Agency awarded ~$1.75B combined to L3Harris ($955M, 18 sats) and Sierra Space ($798M, 18 sats) for Tranche 3 Accelerated Missile Defense tracking satellites; separately, SDA/SpaceX launched 21 Tranche 1 Transport Layer data-relay satellites (York Space Systems-built) on 07-16. Grepped briefs/ — zero prior mentions of either. Neither maps cleanly to a taxonomy thread (missile-tracking/military-mesh, not Intelsat General's comms-services competitive set), and this desk's own REVEALED PRIORITIES record DoD-orbital-contract pushes scoring "Old news" Down twice previously — so not pushed. Flagging as the standing spaceforce.mil weekly-sweep gap (already named in priors) for retro to decide whether Golden Dome's tracking-layer buildout warrants a light-touch priors note.
