SHORT HISTORy
The LRSM program began in 1960
" part of the VELA-Uniform project. It continued until 1971 , when it ."
replaced by the
Special Data Collection System program which remains active. Work under these progrilms h" been directed towards advancing the
seismic-detection, identification, and location techniques necessary to detect and identify underground nuclear explosions.
