# 16th Electromagnetic Warfare Squadron

The 16th Electromagnetic Warfare Squadron (16 EWS) is an active United States Space Force unit, stationed at Peterson Space Force Base, Colorado as part of the Space Delta 3. The squadron protects critical satellite communication links to detect, characterize, geolocate and report sources of electromagnetic interference on US military and commercial satellites. The squadron also provides combat-ready crews to deploy and employ defensive space electromagnetic warfare capabilities for theater combatant commanders. The squadron is Air Force Space Command's first defensive counterspace unit.
From 1967 through 1994, the squadron, originally the 16th Surveillance Squadron, operated the Cobra Dane space detection system at Shemya Air Force Base, Alaska.

## Mission

The 16th Electromagnetic Warfare Squadron operates space electromagnetic warfare capabilities to achieve space superiority in support of theater campaigns and United States Strategic Command's space superiority mission. To achieve this, 16th operates the Rapid Attack Identification Detection Reporting System (RAIDRS) central operating location and up to six RAIDRS fixed ground stations and three deployable ground segments. The unit detects, characterizes, geolocation and electromagnetic interference for satellite communications systems, supporting combatant commanders. 16th SPCS operators can remotely control and task the fixed and deployable antenna suites from Peterson Air Force Base. Additionally, the three deployable systems are capable of sustained autonomous operations if connectivity is lost.

## History
### Cobra Dane operation

The squadron was first organized at Shemya Air Force Station, Alaska as the 16th Surveillance Squadron and assigned to the 73d Aerospace Surveillance Wing of Air Defense Command. The unit's mission was to operate the Cobra Dane long-range early warning radar system, used to track Soviet intercontinental ballistic missile launches. In April 1967, the 73d Wing was inactivated and the 16th was assigned directly to Fourteenth Aerospace Force.
The 16th continued its mission under Air (later Aerospace) Defense Command until the command was disestablished in December 1979. Strategic Air Command assumed responsibility for strategic space defense assets and assigned the squadron to its 47th Air Division. The unit was again reassigned in 1983, when the Air Force brought its space defense and communications units under Air Force Space Command, which assigned the squadron to the 1st Space Wing. In 1991, it was reassigned to the 73rd Space Surveillance Group. In 1992, the unit was designated the 16th Space Surveillance Squadron. It was inactivated in 1994.

### Rapid Attack Identification Detection Reporting System

The unit was reactivated at Peterson Air Force Base., Colorado in May 2007 under the 21st Space Wing to operate the Air Force's Rapid Attack Identification Detection Reporting System (RAIDRS).
The RAIDRS prototype, designated the "Satellite Interference Response System" (SIRS), was initially deployed to United States Central Command (USCENTCOM)'s area of responsibility for a 120-day proof of concept. When the proof of concept proved to be a success, SIRS was redesignated RAIDRS Deployable Ground Segment-0 and has been continually deployed to USCENTCOM since then. In 2011, the Bounty Hunter system was delivered to USCENTCOM for added capability and the two comprise Operation Silent Sentry. Airmen from the 16th and its reserve associate, the 380th Space Control Squadron provide the preponderance of the required manpower for this mission.
On 15 April 2022, the 16th Space Control Squadron was redesignated the 16th Electromagnetic Warfare Squadron.
