SHORT HISTORY
The LRSM program began in 1960 part of the VELA-Uniform project.
" It continued until 1971, when it w" replaced by the
Special Data Collection System program which remains active. Work under these programs h" been directed towards advancing the
seismic-detection, identification, .nd 10('ation te('hniques necessary to detect .nd identify underg;round nuclear explosions.
All work i, accomplished under the technical direction of AFTAC, Vela Seismic Center, in Alexandria, V •.
