SB-AMTI Second Task Order (STR)
STR's share of a $615M combined Space Force OTA package (with Rocket Lab and an undisclosed third vendor) to mature SB-AMTI aircraft-tracking-satellite capabilities.
U.S. Space Force's Space Systems Command awarded STR (Systems & Technology Research) an Other Transaction Agreement as part of the second Space-Based Airborne Moving Target Indicator (SB-AMTI) task order, announced August 4-5, 2026. The $615M combined package was split across three vendors: Rocket Lab ($397M, separately modeled as contract:rocket-lab-sbamti-flatellites-2026), STR, and a third vendor withheld for operational security; STR's individual dollar figure was not disclosed, with reporting indicating the remaining ~$218M is split between STR and the undisclosed vendor. It focuses on vendor-base diversification and integration of multiple sensing technologies/disciplines, building on the program's initial $4.16B SpaceX contract from May 2026 to avoid reliance on a single technical solution.
