This file provides planning information for a solicitation seeking launch services. The Space Development Agency is soliciting proposals to provide launch services for twenty-eight satellite vehicles of two types—twenty transport satellites and eight tracking satellites—with delivery in orbit by no later than March 31, 2023. Ten of the transport satellites are to be launched by Transport Vendor 1 weighing approximately 1,068 kg each, and ten by Transport Vendor 2 weighing approximately 249 kg each. The first launch is required by September 2022 with the entire constellation to be on orbit as close to that date as possible. Proposers should use either a PSC MLB MK2, RUAG PAS 381S, or equivalent ESPA interface for the transport satellites and either an ESPA or 19.848" motorized lightband interface for the tracking satellites. The solicitation also requests details on any considerations such as propellant types or cleanroom standards.
