Instalaza S.A.

Instalaza S.A. is a privately owned Spanish infantry-weapon manufacturer based in Zaragoza, best known in this catalog for the C90 family of shoulder-launched systems and related light infantry weapons.

5 weapons

Instalaza traces its defense history to the early 1950s, when the company says it joined the bazooka project and began building the line of infantry weapons that later led to the C90 family. Its history page also marks 1943 as the formation of INSTALAZA S.A. as the successor to an earlier Instalaciones Zaragoza entity.

For this catalog, Instalaza matters because it is the builder behind the catalog's C90-CR entry and the broader family of reusable and disposable shoulder-launched weapons. The company remains a Zaragoza-based industrial producer with official product pages, a long company history, and a clear link to infantry weapon systems.

Public sources use both the uppercase brand form INSTALAZA and the legal form Instalaza S.A.; this profile normalizes those spellings under the catalog's canonical builder facet. The profile uses an official Zaragoza address, but no separate geocoded headquarters map was added because the company does not publish one directly.
