System Delta 81 (SYD 81) is a unit of the United States Space Force (USSF) that was activated at Peterson Space Force Base on September 9, 2025.[1] The unit supports Space Training and Readiness Command (STARCOM) by developing High-End Advance Test, Training and Tactics (HEAT3), training and live testing including war games and exercises. Col. Corey Klopstein assumed command of the unit as its first leader.[2] The Delta is stationed at Peterson Space Force Base in Colorado Springs, Colorado and is a subordinate to the Space Systems Command. It is the sixth system delta of the USSF.[3]
SYD 81 is part of the USSF's new structure to consolidate acquisition and support SpOC Mission Deltas[4] and is subordinate to the Operational Test and Training Infrastructure (OTTI).[5] This mission will focus on an indefinite delivery/indefinite quantity (ID/IQ) approach to establish a pool of qualified vendors who can fulfill specific requirements to be released in summer 2026.[6]
SYD 81 is developing the Space Warfighter Operational Readiness Domain (SWORD) training environment to train guardians in orbital dynamics, electronic warfare, cyber effects and adversary tactics.[7]
