Overview

Aerostar is a Romanian aerospace and defense company headquartered in Bacău. Its origins can be traced to an aviation maintenance and manufacturing facility established there in 1953. Over time, the company expanded from aircraft repair into military and civil aircraft maintenance, aerospace structures and components, avionics, and defense-system integration. Aerostar has provided long-term support to the Romanian armed forces, including maintenance, modernization and life-cycle services for military aircraft. It also serves civil aviation operators, maintenance organizations and international aerospace partners through maintenance, repair and overhaul activities. The company is primarily an engineering, aviation-support and defense-technology business rather than a consumer-facing product brand. Aerostar is listed on the Bucharest Stock Exchange under the ticker ARS.

History

Aerostar traces its origins to an aviation industrial facility established in Bacău, Romania, in 1953. Its early activities centered on aircraft repair, aircraft manufacturing and related engineering services. As Romania's aerospace industry developed, the company built capabilities in military-aircraft maintenance, aerospace structures, avionics and defense equipment. Its business has not been focused on a single consumer product or aircraft type; instead, it has emphasized aircraft maintenance, modification, modernization and long-term technical support. Aerostar later expanded into civil aviation maintenance, repair and overhaul, serving aircraft operators and international customers. The company has remained an important participant in Romania's defense-industrial sector and has also taken part in international aerospace maintenance and manufacturing supply chains. It subsequently became a listed company on the Bucharest Stock Exchange and continues to focus on aerospace engineering, aircraft support and defense-system integration.
