Space Delta 3 – Space Electronic Warfare, held its change of command July 30, 2021, at Peterson Space Force Base, Colorado.

During the ceremony, U.S. Space Force Col. Christopher Fernengel accepted command from USSF Col. John Thien, outgoing commander. Prior to taking command of Space Delta 3, Fernengel was the division chief for operational capability requirements for the U.S. Space Force Chief of Strategy and Requirements Office at the Pentagon.

The Space Delta 3 mission, part of the newly developed U.S. Space Force, is to conduct space electronic warfare. Space electronic warfare focuses on enabling and protecting the electromagnetic spectrum which allows space-based communications. Space Delta 3 includes both offensive and defensive space control operations. Offensive space control is intended to prevent an adversary’s hostile use of space capabilities, while defensive space control focuses on identifying and geolocating interference with U.S. capabilities.

Space Delta 3 is comprised of the 4th Space Control Squadron, 5th SPCS, 16th SPCS and 721st Operations Support Squadron, also located at Peterson Space Force Base, and has about 300 personnel among its ranks.
