SDA Seeks Industry Input on Tranche 2 Tracking Layer Program

1 min read

The Space Development Agency has published a request for information on the second tranche of the Proliferated Warfighter Space Architecture’s tracking layer that will support missile defense missions.

A notice posted Monday on SAM.gov states that the Tranche 2 Tracking Layer architecture will provide global surveillance and targeting services from the low-Earth orbit and enable continuous missile warning and tracking capabilities.

The T2 Tracking Layer will also deliver a missile defense fire control capability expected to deploy to LEO in fiscal year 2027.

SDA is seeking industry input on constellation architecture, mission data processing parameters and infrared mission payload development.

L3Harris Technologies and Northrop Grumman secured prototyping agreements worth $1.3 billion in July 2022 to build and deploy 28 satellites for the T1 Tracking Layer.

Each spacecraft will include an infrared mission payload, optical communications terminals, a Ka-band communications payload and multiple pointing modes.

In late January, SDA renamed the National Defense Space Architecture as the PWSA to better reflect its mission to provide space-based warfighting capabilities.
