[6] Initially founded in 1955 as an ammunition repair and anti-aircraft artillery factory, Electromecanica has changed its name multiple times since then.
Having gone through multiple upgrades throughout its existence, Cugir Arms Factory now produces products compatible with NATO standards.
[14] It was established on 5 November 1938 as Întreprinderea Română Mecanică şi Chimică (the "Romanian Mechanical and Chemical Enterprise").
3010/1939, the Sadu Mechanical Plant is the successor to Pirotehnia Armatei ("Army Pyrotechnics"), which was founded in Bucharest in 1861.
[18] In 1970, the Sadu II industrial platform was built for the manufacture of infantry weapons, primers for the various types of ammunition, as well as mining explosives.
From 2002, it became a subsidiary to ROMARM, and from 2014 it changed its name to Societatea "Uzina Mecanică Sadu" SA.
In December 1990, it received the name the "Bucharest Mechanical Plant", being taken over by the Ministry of National Defense, as a component unit of the Army Industrial Group - Autonomous Directorate.
After 10 years, the plant comes under the authority of the Ministry of Industry and Resources and is renamed S.C. "ARSENAL" S.A. - Bucharest branch.
[20] In 2001, following the reorganization of the defense industry, the unit reverted its name to the Bucharest Mechanical Plant and became a subsidiary of ROMARM.
[20] The factory currently produces Mowag Piranha V armored vehicles as a joint venture with General Dynamics European Land Systems.
