Ballistic Research Laboratory
From Wikipedia, the free encyclopedia
The Ballistic Research Laboratory (BRL) at Aberdeen Proving Ground, Maryland was the center for the United States Army's research efforts in ballistics and vulnerability/lethality analysis.
In 1992, its mission, personnel, and facilities were incorporated into the newly created Army Research Laboratory, and BRL was disestablished.
[edit] Computers
BRL played an important role in the history of computer development:[1][2]
- Sponsored the development of ENIAC - widely regarded as the first general-purpose electronic digital computer - to aid the creation of firing tables for artillery and mortars
- Developed and built several generations of computers: EDVAC, ORDVAC and BRLESC[3]
- Developed BRL-CAD, a solid geometric modeling system - now open sourced
- The network ping utility was authored by Mike Muuss of BRL in December 1983 to troubleshoot network problems[4][5]
