The Space Development Agency awarded approximately $3.5 billion in contracts on December 19, 2025 to four companies for 72 missile-tracking satellites — the next phase of a low-Earth-orbit constellation built to detect and track advanced missile threats. Each prime builds 18 satellites. Coverage from SpaceNews, Air & Space Forces Magazine, and SDA.

The award split

PrimeAwardSatellites
Lockheed Martin$1.1 billion18
L3Harris Technologies$843 million18
Rocket Lab USA$805 million18
Northrop Grumman$764 million18
Total$3.5B72

What each satellite carries

  • Infrared sensor (primary missile-tracking payload)
  • Optical communications terminal
  • Ka-band communications payload
  • S-band backup telemetry/tracking/command

72 satellites deploy across 8 orbital planes; launches scheduled FY29.

What this signals

Rocket Lab's inclusion at $805M is the company's largest defense win — confirming SDA's commitment to a multi-vendor, non-traditional-friendly procurement model. General Atomics will deliver IR payloads under Lockheed's prime contract, opening a Tier-2 supply path for specialty payload firms.

What to do

  • IR sensor specialists: General Atomics-Lockheed teaming is the precedent — pursue similar payload subcontracts under the four primes
  • Optical-communications firms: 72 OCTs is meaningful subsystem volume
  • Ground-system and integration firms: Tracking Layer requires extensive ground infrastructure
