… but wrong !
SNEB means ‘Societe Nouvelle des Etablissements Edgar Brandt’. If I dare writing it with french accents, as your browser may not read them: Société Nouvelle des Etablissements Edgar Brandt.
You can see below the history of this company til now. So-called SNEB rockets, Brandt rockets, Thomson rockets are the same, produced in France since 1950, just the company changed name. The only synergy in airborne rockets was in 1988 when Thomson bought Belgium co ‘Forges de Zeebruge’ (actually located in Herstal, not in Zeebrugge) and added its FZ 2.75″ licence poduced rocket assortment to its own ‘catalogue’. The company is now TDA Armements, a JV between Thales and EADS.
