Overview
Nostromo Defensa is an Argentine aerospace and defense company based in Córdoba. The company has worked since 2006 on the development of unmanned aerial vehicles for military and non-military applications. Its activities place it within Argentina’s small but historically significant aerospace and defense-industrial ecosystem, where private engineering firms, state institutions, and military users have contributed to the development of locally designed aircraft and unmanned systems. The company’s publicly documented work includes several unmanned or light-aircraft projects carrying names drawn from regional wildlife and folklore. These include the Caburé, Yaguá, and Yarará aircraft projects, as well as the Centinela helicopter. The Yarará project was developed for the Argentine Air Force, linking Nostromo Defensa’s product development work to an identified national military customer. The company also developed and manufactured the Centinela helicopter, indicating that its activities have extended beyond unmanned fixed-wing aircraft into rotary-wing aviation. Nostromo Defensa’s portfolio is associated primarily with reconnaissance, surveillance, and other defense or civil applications for unmanned aviation. The available reference material does not provide a complete account of production volumes, commercial customers, export contracts, revenues, ownership, or the operational status of each aircraft model. It also does not establish a formal founding date beyond describing the company as working in this field since 2006. Accordingly, the company is best characterized as an Argentine aerospace and defense developer and manufacturer with a documented emphasis on unmanned aerial vehicles and related aircraft rather than as a large diversified defense conglomerate. Marcelo Martínez is identified as the company’s chief executive officer. Publicly available information about the company’s corporate structure, workforce, facilities, financing, international sales, and current product lineup is limited. Its known projects nevertheless make Nostromo Defensa a notable participant in Argentina’s effort to develop indigenous unmanned-aircraft capabilities for military and non-military use.
History
Nostromo Defensa is an aerospace and defense company from Córdoba, Argentina. The available historical record describes the company as having worked since 2006 on unmanned aerial vehicles intended for both military and non-military uses. This places its development activity in a period when unmanned aircraft were becoming increasingly important for surveillance, reconnaissance, border monitoring, environmental observation, and other missions that could be performed without placing a crewed aircraft at risk. The company’s documented work has centered on a family of aircraft projects. The Nostromo Yarará was developed for the Argentine Air Force, establishing a direct connection between the company and a national military aviation institution. The project represents an effort to provide an indigenous unmanned-aircraft capability rather than relying exclusively on foreign systems. The available sources do not specify the full procurement history, production quantity, service record, or final operational status of the Yarará, so those aspects remain undocumented in this entry. Nostromo Defensa’s listed aircraft also include the Caburé and Yaguá. The source material identifies these as models in the company’s aircraft portfolio but does not provide enough technical or commercial information to distinguish their detailed configurations, launch dates, customers, or production histories. They are therefore recorded here as associated aircraft projects rather than assigned unverified specifications or roles. The company also developed and manufactured the Centinela helicopter. This work demonstrates that Nostromo Defensa’s engineering scope was not limited to fixed-wing unmanned aircraft. However, the available reference does not establish whether the Centinela was produced in quantity, entered regular service, or remained a development and demonstration program. Marcelo Martínez is identified as the company’s chief executive officer. Beyond that executive reference, publicly available material supplied for this dossier provides little information about ownership, corporate transactions, financing, organizational changes, export activity, or later product generations. No verified revenue figures, stock-market listing, parent company, or official corporate website are available in the reference set. The company should therefore be understood from the documented record as a Córdoba-based Argentine aerospace and defense developer and manufacturer whose principal historical identity is tied to unmanned aerial vehicles and a small portfolio of locally developed aircraft.

Products and positioning
Argentine aerospace and defense developer specializing in unmanned aerial vehicles and locally developed aircraft for military and non-military applications.
Unmanned aerial vehicle
Nostromo Yarará
The Yarará is an unmanned aircraft project developed by Nostromo Defensa for the Argentine Air Force. It is the company’s clearest documented military-customer program and reflects its focus on developing domestically produced unmanned systems. The available material does not provide verified specifications, production numbers, deployment history, or current service status.
Helicopter
Nostromo Centinela
The Centinela is a helicopter developed and manufactured by Nostromo Defensa. Its inclusion in the company’s aircraft portfolio shows that the company’s engineering work extended beyond unmanned fixed-wing vehicles into rotary-wing aviation. The supplied references do not establish the aircraft’s precise configuration, production scale, customers, or operational status.
Aircraft
Nostromo Caburé
Caburé is one of the aircraft models associated with Nostromo Defensa. The reference material lists the model among the company’s aircraft, but does not provide reliable details on its configuration, intended mission, launch date, customers, or production status. It is therefore recorded as a documented portfolio model without additional technical claims.
Aircraft
Nostromo Yaguá
Yaguá is a Nostromo Defensa aircraft model identified in the company’s documented portfolio. Available source material does not specify whether it was a military or civil design, nor does it establish its detailed specifications, manufacturing history, customers, or operational status.
