SDA seeks industry submissions to recompete 10 Tranche 2 Transport Layer (T2TL) Gamma variant space vehicles. This solicitation is for the Gamma (γ) variant of the Tranche 2 Transport Layer (T2TL) to be executed by the Advanced Fire Control (AFC) Program. AFC delivers operationally relevant prototypes and integrated ground to inform and influence future Tranches. There is a potential for future mission integration of AFC prototypes into the Proliferated Warfighter Space Architecture (PWSA) operational architecture. 

SDA seeks T2TL Gamma space vehicles with a payload specifically designed to close future kill chains. The Gamma variant will share certain baseline characteristics with the other T2TL variants (Alpha and Beta) outlined in earlier solicitations. Further, SDA expects to make a T2TL-Gamma award to one vendor, subject to available funding, but reserves the right to make no awards or a partial award of less than 10 SVs.

To promote fair and open competition, at the direction of the head of contracting activity, SDA enlisted the support of independent source selection officials from outside the agency who will lead Source Selection activities.

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