Overview

Saab Surveillance is the Saab AB business associated with radar, sensor, surveillance and electronic-warfare capabilities for defence customers. Its direct predecessor was Ericsson Microwave Systems, founded in Sweden in 1956. Saab acquired the business and renamed it Saab Microwave Systems in 2006; the activity is now identified with Saab Surveillance within Saab's broader defence portfolio. The business serves the sensor and electronic-warfare segment of the defence industry. Its publicly identified product heritage includes Erieye airborne early warning and control systems, ARTHUR artillery-hunting radar, the Giraffe family of agile multi-beam air-defence search radars, the PS-05/A fighter-aircraft radar, and HARD 3D radar systems for helicopter and aircraft detection. These products cover several operational needs: detecting and tracking airborne targets, locating artillery fire, supporting air-defence networks, equipping combat aircraft, and providing situational awareness for military users. Saab Surveillance's principal markets have been described as Europe, South Africa, Australia and the United States. The business reflects Saab's emphasis on integrated defence technologies rather than consumer branding: its offerings combine hardware, sensors, software and mission-system functions for national armed forces and other governmental customers. The available reference material does not identify a standalone headquarters, separate public listing, independent revenue figure or current executive team for Saab Surveillance itself. In the context of Saab AB, the surveillance activity forms part of a wider structure that has included Aeronautics, Dynamics, Electronic Defence Systems, Security and Defence Solutions, and Support and Services. Saab reorganised its operations into five business areas from 1 January 2010, reflecting an effort to align the company with changing conditions in the defence industry. Saab Surveillance should therefore be understood as a specialised Saab defence brand and business activity, rather than as an independently listed company.

History

Saab Surveillance traces its origins to Ericsson Microwave Systems, a Swedish business established in 1956. The company developed microwave and radar expertise for military applications, eventually becoming associated with a range of airborne, ground-based and air-defence sensing systems. A major ownership and identity change took place in 2006, when Saab acquired the business from Ericsson and renamed it Saab Microwave Systems. This transaction brought the microwave, radar and sensor activity into Saab AB's defence portfolio. The business subsequently became associated with Saab Surveillance, reflecting its concentration on surveillance, sensing and electronic-warfare missions. The product heritage connected with the activity includes Erieye airborne early warning and control, ARTHUR artillery-hunting radar, the Giraffe family of air-defence search radars, the PS-05/A fighter radar and HARD 3D detection radar. Together, these systems represent the business's principal technical domains: long-range and tactical surveillance, target tracking, counter-battery location, air-defence command support and aircraft-based sensing. Saab's reference material identifies Europe, South Africa, Australia and the United States as important markets. The business has consequently operated in an international defence environment in which customers typically procure systems through government programmes, military modernisation initiatives and long-term support arrangements. The available material does not provide a separately reported corporate history for Saab Surveillance after its integration into Saab AB, nor does it identify a distinct current legal entity, headquarters or management roster. From 1 January 2010, Saab divided its operations into five business areas: Aeronautics, Dynamics, Electronic Defence Systems, Security and Defence Solutions, and Support and Services. This reorganisation placed the surveillance and electronic-defence activities within Saab's wider business-area structure. Saab Surveillance is therefore best treated as a Saab AB defence brand or business activity whose roots lie in Ericsson's microwave systems operation, rather than as a separately listed public company.
