SDA Releases Updated DRAFT Solicitation for Tranche 1 Demonstration and Experimentation System (T1DES)

Original Response Date: June 3, 2022

The Space Development Agency (SDA) seeks input through a Tranche 1 Demonstration and Experimentation System (T1DES) DRAFT solicitation. SDA previously released a DRAFT Request for Proposal (RFP) on this topic in late 2021; however, this document is updated to a DRAFT solicitation to reflect the Agency’s updated acquisition strategy. SDA plans to solicit solutions for space systems to augment the Tranche 1 Transport Layer (T1TL) constellation with demonstration and experimentation capability. T1DES leverages the low latency data transfer and beyond-line-of-sight command and control infrastructure established by the T1TL program to field and connect additional space vehicles. These space vehicles will demonstrate and evaluate new mission payloads for proliferation in future tranches of the Transport Layer. This solicitation is for development, manufacture, test, launch integration, and deployment of the T1DES space vehicles, payloads, and mission-enabling ground systems.
