Space Control Squadron #4 and #5

Welcome to the official website for the Environmental Assessment for Beddown of Space Control Squadrons #4 & #5 (SPCS #4 & SPCS #5) at two Air National Guard (ANG) locations. This website: 

  • notifies the public about our intent and
  • shares information with the public about the proposed action and alternatives.

What and Where are SPCS #4 and SPCS #5?

The proposed action would beddown one offensive mission (SPCS #4) and one defensive mission (SPCS #5) at two ANG locations.  The locations being considered are Pacific Missile Range Facility (PMRF) at Barking Sands, Kauai, Hawaii (preferred alternative for SPCS #4); Joint Base Pearl Harbor-Hickam (JBPHH), Oahu, Hawaii; and Andersen Air Force Base (AFB), Guam (preferred alternative for SPCS #5).  The locations will construct a 12,100 square foot building, 5,000 square yard equipment pad with an unobstructed view of geosynchronous satellites, 2,500 square yard parking lot within a quarter mile of the facilities, a 50-foot security clearance setback throughout the perimeter of the equipment pad, an infiltration basin, and a 50-ton air conditioner unit.  SPCS #4 would require between 88 and 115 new ANG personnel to support the offensive mission, while SPCS #5 would requirement between 62 and 105 ANG personnel to support the defensive mission.

Why is ANG Bedding Down SPCS #4 and SPCS #5?

The proposed action would provide facilities and locations to establish two ANG SPCS locations with access to geosynchronous satellites in the Pacific theater.  SPCS #4 is an offensive mission needed to meet Combat Command requirements for offensive space control at four ANG locations.  SPCS #4 will be the fourth of four ANG SPCS offensive missions.  SPCS #5 is a defensive mission needed to meet Combat Command requirements for defensive space control at eight ANG units.  SPCS #5 would be the first of eight ANG SPCS defensive missions.

The National Environmental Policy Act (NEPA) is our national charter for making informed decisions based upon potential environmental consequences. NEPA requires all federal agencies to take a good-faith, hard look at potential environmental consequences of a proposal before making a decision.


The Draft Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) will be posted to this webpage once they are ready for public review/comment.  They are expected to be posted in the early summer.
