QinetiQ was originally formed in July 2001, when the UK Ministry of Defence split its Defence Evaluation and Research Agency (DERA) in two. The smaller portion of DERA was rebranded Dstl (Defence Science & Technology Laboratory) and the larger part, including most of the non-nuclear testing and evaluation establishments, was renamed QinetiQ and became a public private partnership in 2002.The company was successfully floated on the London Stock Exchange in 2006.
