CETME (Spanish: Centro de Estudios Técnicos de Materiales Especiales, lit.
'Centre for Technical Studies of Special Materials')[1] is a Spanish government design and development establishment.
While being involved in many projects CETME was mostly known for its small arms research and development.
The Spanish government hired former semiautomatic weapon designers from the Third Reich[2] for the organization.
CETME also designed the CETME C2 9mm submachine gun, and the CETME Ameli light machine gun in 5.56×45mm NATO.
