TheNational Security Space Institute (NSSI) is a unit in theUnited States Space Force'sSpace Training and Readiness Command (STARCOM). Headquartered atPeterson Space Force Base,Colorado, it provides spaceprofessional military education to the military space professionals in the United States and its allies.[2][3]
NSSI's history can be traced back as far as 2001 when the Air Force Space Operations School was activated on 28 July 2001 under theSpace Warfare Center (later redesignated as Space Innovation and Development Center) atSchriever Air Force Base, Colorado. On 2004, it was redesignated as the National Security Space Institute and realigned under theAir Force Space Command and was subsequently transferred to its current location at Peterson Air Force Base.[4] In 2009, it was realigned underAir Education and Training Command and remained there under various units in itsAir University until 2020 when it was transferred to the Space Force to form part of the initial structure of STAR Delta (P).[2][5] In August 2021, STAR Delta (P) was stood up as the USSF's third field command and given the name Space Training and Readiness Command (STARCOM).
In 2019, it established three new courses: Space 100, Space 200, and Space 300. It also started accepting participation of foreign nationals from coalition partners of the United States, an initiative of formerSecretary of the Air ForceHeather A. Wilson.[6][7] Since 2019, the NSSI has grown from offering three courses to sixteen organized under two colleges: the College of Space Warfare and the College of Professional Development. The institute now serves more than 50 allied and friendly partners from across the globe.
