SDA Issues Request for Information for Tranche 2 Transport Layer- Gamma Variant Space Vehicles

Posted On: October 23, 2023

Response Date: Monday, November 6, 2023

SDA seeks industry feedback for the final of three variants of Tranche 2 Transport Layer (T2TL) space vehicles—T2TL Gamma. This request for information (RFI) expands upon the foundation for Tranche 2 of the Proliferated Warfighter Space Architecture (PWSA) previously described in the T2TL Alpha and Beta solicitations.

SDA expects to procure approximately 20 T2TL Gamma space vehicles with a payload specifically designed to close future kill chains via the PWSA. The Gamma variant will share certain baseline characteristics with the other T2TL variants (Alpha and Beta) outlined in the RFI.

T2TL features multiple space vehicle and mission configuration variants procured through a multi-solicitation and multi-vendor acquisition approach. The initial launch capability is scheduled for September 2026.

The details of this RFI are classified and seek to inform the development of the payload capability as part of the T2TL Gamma solicitation process. Vendors wishing to respond must do so on the network defined in the submission instructions.
