SDA Awards Contracts for 36 Golden Dome Missile Tracking Satellites

TL;DR

The Space Development Agency awarded $1.75 billion in contracts to L3Harris and Sierra Space for 36 missile tracking satellites under the Golden Dome missile defense program's Tranche 3, bringing the tranche total to 104 spacecraft with delivery expected by late 2028. This award materially expands the Pentagon's low Earth orbit missile warning and tracking constellation and reflects congressional pressure to accelerate the program. The decision signals continued near-term investment in space-based missile defense capabilities and creates substantial opportunities across the space defense industrial base. Contractors in satellite manufacturing, space systems, defense electronics, and associated support areas should treat this as a high-priority market signal and move immediately to validate capture posture, compliance readiness, and teaming options. Cabrillo Club has already detected and flagged this event for customers via the War Room; use our proposal and intelligence tooling to rescore pipelines, run bid/no-bid analyses, and harden compliance artifacts for ITAR (International Traffic in Arms Regulations), CMMC (Cybersecurity Maturity Model Certification), NIST 800-171 (NIST Special Publication 800-171), DFARS (Defense Federal Acquisition Regulation Supplement), and EAR surfaces.

Intelligence Response

• Cabrillo Signals War Room — Already detected this event and delivered this briefing. War Room will continue to push event alerts and executive summaries to subscribed capture and BD teams.
• Cabrillo Signals Match Engine — Automatically rescored opportunity pipelines and competitor impact models based on the awards to L3Harris and Sierra Space and the expanded tranche size.
• Cabrillo Signals Intelligence Hub — Tracking affected NAICS codes, the Golden Dome contract vehicle, and Space Development Agency activity; saved searches will alert when follow-on solicitations or amendments appear on public solicitation portals (saved searches include SAM.gov (System for Award Management) monitoring as part of the Intelligence Hub workflow).
• Proposal Studio (Proposal OS) & Proposal Studio Workflow Tracker — Use Proposal Studio to generate compliance matrices (CMMC, NIST 800-171, ITAR, DFARS, EAR) and draft win themes; route tasks through the Workflow Tracker’s 9-gate capture process to create audit-ready documentation.

Who to notify immediately: Capture Manager, Business Development Lead, Proposal Manager, Program Security Officer, Chief Engineer, Contracts Lead. Primary actions in the first 48 hours are outlined below.

First 48-hour response playbook

• Hour 0–4: Cabrillo Signals War Room distributes alert and the captured intelligence package; run an immediate Match Engine rescore of your active pipeline; notify Capture Manager, BD Lead, Proposal Manager, and Program Security Officer.
• Hour 4–12: Use Intelligence Hub saved searches to watch for solicitation updates; stand up a capture cell and start a bid/no-bid using Proposal Studio; start compliance gap assessment for ITAR/CMMC/NIST 800-171/DFARS/EAR.
• Hour 12–24: Complete initial win strategy and resource plan in Proposal Studio; route the capture plan and compliance assignments through Proposal Studio Workflow Tracker; initiate teaming outreach and sub-tier mapping.
• Hour 24–48: Lock assignment of proposal sections, finalize initial cost/resource estimates, collect baseline security artifacts and export-control plans, and configure continuous monitoring alerts in Intelligence Hub for follow-on solicitations and related DOD activity.
