SPAWAR Systems Center Pacific (SSC) and the Air Force Research Laboratory (AFLR) have developed the Counter Tunnel System as a complementary development effort of NORTHCOM's Rapid Reaction Tunnel Detection (R2TD) JCTD. The R2TD system addresses the "objective" tunnel-exploration requirements, but has only 2D perception and limited mapping techniques in non-planar, complex environments. Based off of the R2TD principles, the Counter Tunnel System goal is to provide the Warfighter and law enforcement:
- a safe and effective solution for 3D localization, mapping, and characterization of a tunnel-like environment
- a capability to identify items of interest within the environment
- a capability to locate the point(s) of entry.
