Overview

Havelsan is a Turkish software and systems company headquartered in Ankara and focused primarily on defense, security, aviation, naval, and public-sector information technologies. Established in 1982 by the Turkish Air Force Foundation under the name Havelsan-Aydin, the company initially supported the maintenance of high-technology radar systems used by the Turkish Air Force. In 1985, it became a nationally controlled company after the separation of its foreign shareholders, with the Turkish Armed Forces Foundation holding the dominant share. The company’s role expanded substantially during the 1990s. In 1997, Havelsan added command, control, communications, computers, intelligence, surveillance, and reconnaissance capabilities; training and simulation systems; and management information systems to its activities. This broadened the company from a maintenance-oriented defense supplier into a developer and integrator of complex software-intensive systems. Its work has included command-and-control architectures, naval combat management, reconnaissance and surveillance, intelligence applications, logistics support, homeland security, energy management, and training environments. Havelsan also operates beyond conventional military programs. It has developed major Turkish e-government and public-administration systems, including election, justice, land-registry, and cadastral information platforms. These projects positioned the company as an important systems integrator for government institutions as well as a defense contractor. Its public-sector work has included the Computer Supported Central Elections Registry System, known as SEÇSİS; the National Justice Information System, or UYAP; and the Land Registry and Cadastre Information System, or TAKBİS. In aviation, Havelsan has participated in the Peace Eagle airborne early-warning and control program, where its responsibilities have included ground-support functions such as crew training, mission planning, and software maintenance. The company has also pursued international subcontracting opportunities connected with airborne early-warning and control programs, although one proposed Boeing subcontracting relationship for Italian and Korean projects was withdrawn by Boeing in 2009. Havelsan’s positioning is based on domestic control of sensitive technologies, integration of software with complex defense platforms, and the development of systems intended to operate across land, air, maritime, governmental, and security environments. Its offerings are generally institutional rather than consumer-facing: they are procured by armed forces, government agencies, public institutions, and industrial partners. The company’s public profile therefore comes mainly from large defense and e-government programs rather than from mass-market products. The company has received recognition in Turkish technology, quality, export, and e-government programs. It was identified by the Turkish Quality Association as the first defense-industry company represented on its national quality map, and several of its government information systems received awards in Turkish e-government competitions. Havelsan has also appeared in Turkish rankings of information-technology and industrial companies. Its continuing activities center on defense software, simulation and training, command systems, public-sector information infrastructure, and integrated security technologies.

History

Havelsan was established in 1982 by the Turkish Air Force Foundation as Havelsan-Aydin. Its initial purpose was to provide maintenance for advanced radar systems operated by the Turkish Air Force. This origin gave the company a direct connection to Turkey’s defense-industrial modernization efforts and placed it within a foundation-controlled national technology structure. In 1985, Havelsan was separated from its foreign shareholders and reorganized as a nationally controlled company. The Turkish Armed Forces Foundation held approximately 98 percent of the company at that stage, reinforcing Havelsan’s role as a domestic supplier of strategically important defense technologies. A major transformation took place in 1997, when Havelsan expanded beyond maintenance and related technical services. It began developing command, control, communications, computers, intelligence, surveillance, and reconnaissance systems; simulation and training technologies; and management information systems. These additions changed the company’s profile into that of a software and systems house capable of designing and integrating complex defense architectures. Havelsan subsequently applied its software and systems expertise to both military and civilian government programs. Its public-sector projects included the National Justice Information System, the Land Registry and Cadastre Information System, and the Computer Supported Central Elections Registry System. These systems supported judicial administration, property and cadastral records, and election-related processes. Their recognition in Turkish e-government competitions helped establish Havelsan as a government-technology provider as well as a defense contractor. In the defense aviation sector, Havelsan became one of the subcontractors associated with the Peace Eagle project. Its responsibilities principally covered the ground-support segment, including crew training, mission planning, and software maintenance. The company also attempted to expand its international role by pursuing a main-subcontractor relationship with Boeing for Italian and Korean airborne early-warning and control projects. Boeing withdrew from that subcontracting arrangement in early 2009. The company’s broader portfolio has remained centered on software-intensive and integrated systems. Its areas of activity include C4ISR, naval combat systems, reconnaissance and surveillance, intelligence, simulation and training, logistics, homeland security, management information, and energy management. Rather than competing primarily in consumer electronics, Havelsan serves armed forces, government agencies, and institutional customers that require secure, specialized, and long-life systems. Havelsan has received recognition from Turkish quality, technology, export, and e-government organizations. It was presented as the first defense-industry company on the Turkish Quality Association’s national quality map. Its election, justice, and land-registry systems were recognized in national e-government award programs, while the company also appeared in Turkish rankings for information-technology firms, exporters, and rapidly growing companies. These recognitions reflect the dual character of Havelsan: a defense-oriented engineering company and a developer of national public information infrastructure.
