The agency “will initially focus on rapidly developing and fielding new space capabilities that leverage commercial space technology and access in support of warfighter and U.S. Space Command,” says the memo. “The concepts should clearly define the relationship between the warfighter and the SDA.” Over time the SDA will assume responsibility for other space development programs. The proposed concepts should “include a transition plan for consolidating space development efforts under the SDA as the equipping arm for the space warfighter, with an initial operating capacity in calendar year 2019.”
