Response Date: April 30, 2024

SDA seeks industry submissions for the final of three types of Tranche 2 Transport Layer (T2TL) space vehicles—T2TL Gamma. This solicitation 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 solicitation.

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 T2 Gamma solicitation is comprised of unclassified solicitation documents as well as classified material on technical details of payload development.
