The 346 TS is a subordinate unit under the 318th Cyberspace Operations Group, 688th Cyberspace Wing, 24th Air Force at JBSA-Lackland, Texas.

The 346th Test Squadron (346 TS), located at Joint Base San Antonio-Lackland, Texas, provides military-focused cyberspace operational testing capabilities to the joint warfighting team.

Conduct independent, credible and rigorous operational test & evaluations, emissions security tests, and other specialized tests of cyberspace capabilities and operate Air Force Space Command’s cyber test & training range to enhance the military utility of cyberspace.

Rapidly ensuring cyber meets warfighter needs.


Over 120 professionals, representing 14 Air Force Specialty Codes, perform the 346 TS mission.  The Squadron consists of approximately 50 active duty, 30 civilians and 40 contractors with expertise ranging in operational cyber testing, cyber test and training range, Telecommunications and Electrical Machinery Protected from Emanations Security (TEMPEST) testing and unified capabilities testing.

The 346 TS is part of the 318th Cyberspace Operations Group and 688th Cyberspace Wing, both located at Joint-Base San Antonio-Lackland, Texas, which are aligned under 24th Air Force and Air Force Space Command.  The Squadron performs its mission in partnership with Air Force Life Cycle Management Center (AFLCMC), Air Force Operational Test and Evaluation Center (AFOTEC), Air Force Certified TEMPEST Test Authority (AF/CTTA) and Defense Information Systems Agency (DISA).

Cyberspace Capabilities:
The 346 TS conducts operational tests, under realistic combat conditions, for any item or component of a weapons system, equipment, or software for the purpose of determining its operational effectiveness & suitability.  In addition, sound statistical analysis of operational test results provides accurate estimates of information to acquisition decision-makers, as well as identifies unexpected critical system performance issues that would have affected the systems’ combat effectiveness, thus providing significant cost savings from discovering problems before system fielding.  

The 346 TS traces its organizational lineage to World War II.  It was constituted on 28 January 1942 as the 346th Bombardment Squadron (Heavy) and activated on 1 June 1942 at Orlando Air Base, Florida, as part of the 99th Bombardment Group.  On 29 September 1944 it was redesignated as the 346th Bombardment Squadron, Heavy.  The squadron was inactivated on 8 November 1945 at Marcianise, Italy, subsequently redesignated 346th Bombardment Squadron, Very Heavy, on 13 May 1947, and activated in Reserve status on 29 May 1947 at Birmingham Municipal Airport, Alabama.  It was again inactivated on 27 June 1949.  The squadron was redesignated as the 346th Strategic Reconnaissance Squadron, Heavy, and activated yet again on 1 January 1953 under the 99th Strategic Reconnaissance Wing (later the 99th Bombardment Wing).  It would return to the 346th Bombardment Squadron, Heavy, designation on 1 October 1955.  The squadron inactivated again on 31 March 1974 at Westover AFB, Massachusetts.
