What Is Thales? Inside France’s Radar and Defence-Electronics Giant

Thales is a French global defence, aerospace and digital-security group that has built its reputation not on tanks or fighter jets, but on the eyes, ears and brains that make those platforms work: radars, sonars, electronic-warfare suites, combat-management software, military communications and cyber security. With revenue of €22.1 billion in 2025, the group ranks as the world’s 15th-largest arms producer and stands among the quiet but indispensable suppliers behind NATO and European defence programmes.

What Is Thales, and Where Is It From?

Thales is a French company headquartered in the La Défense business district of Paris. Its roots trace back to Thomson-CSF, formed in 1968 from the merger of Thomson-Brandt’s professional-electronics arm with CSF (Compagnie Générale de Télégraphie Sans Fil). The company adopted its current name, Thales — a nod to the ancient Greek philosopher and scientist Thales of Miletus — in December 2000. Around the same time it created ThalesRaytheonSystems with America’s Raytheon, one of the first transatlantic joint ventures in the defence sector.

The shortest way to understand Thales is this: it is a systems-and-sensors house. In an air-defence battery, MBDA may build the missile and another firm the launcher vehicle — but the radar that sees the target hundreds of kilometres away, and the command-and-control software that ties everything together, is very often supplied by Thales. That positioning makes the company the owner of defence’s invisible but critical infrastructure.

Thales at a Glance

Its ownership structure sets Thales apart from an ordinary listed company: roughly a quarter of its shares are held directly by the French state and a comparable stake by fighter-maker Dassault Aviation. That makes Thales an effective instrument of French national-security strategy and ties what it can sell, and to whom, to political decisions in Paris. In 2024 the group sold its lower-margin, cyclical ground-transportation (signalling) business to Hitachi Rail, shifting its centre of gravity toward defence, aerospace and the cyber-digital domain.

The financial momentum is directly linked to the surge in European defence spending that followed Russia’s invasion of Ukraine. In 2025, defence order intake hit a segment record of €15.1 billion, with a book-to-bill ratio of 1.24 — meaning the company is booking orders faster than it is delivering them. In 2024, about 72% of group revenue came from military activities.

What Does Thales Do?

• Radar systems: ground-based air-defence radars (the Ground Master family) and naval radars (SMART-S, the NS series) — the company’s flagship domain.
• Air defence: the STARStreak and Martlet missiles, the RAPIDFire gun system and the TopSky command-and-control layer.
• Electronic warfare and signals intelligence: systems that detect and jam hostile radar and communications.
• Command and control: TACTICOS at sea and TopSky for airspace battle and traffic management.
• Naval systems and sonar: the CAPTAS towed-sonar family and ship-integration solutions, plus a 25% stake in Naval Group.
• Military communications: the SYNAPS software-defined radio family and the CONTACT tactical network.
• Avionics: the FlytX cockpit suite, flight-control computers and the TALIOS targeting pod.
• Space: satellites via the Thales Alenia Space joint venture and the Syracuse military-communications programme.
• Cyber security and digital identity: data and network security through brands such as Imperva and CipherTrust, and passports, SIMs and bank cards via Thales DIS.

Flagship Products and Programmes

Ground Master (GM200/GM400): The umbrella brand for Thales’s ground-based air-surveillance radars. The long-range, three-dimensional GM400 Alpha tracks everything from low-flying drones to ballistic missiles out to several hundred kilometres and is widely used across NATO. The more compact GM200 serves mobile, medium-range missions; its main rivals are Germany’s Hensoldt TRML series and Israel’s ELTA radars.

SMART-S Mk2 and the NS100/NS200: SMART-S Mk2 is a rotating mid-range naval surveillance radar fitted to frigates and corvettes worldwide, while the NS100/NS200 are fixed-face (AESA) next-generation naval radars. This family matters to Türkiye in particular: Thales sources the transmit/receive (T/R) modules for its SMART-S Mk2 radars from ASELSAN, with delivery of the first 100 modules beginning in 2015.

CAPTAS sonar and TACTICOS: CAPTAS is a low-frequency towed sonar family for hunting submarines, one of Europe’s reference systems in anti-submarine warfare. TACTICOS is the combat-management system (CMS) that fuses a warship’s sensors and weapons onto a single screen — the “brain” of dozens of navies’ vessels.

STARStreak, Martlet and RAPIDFire: STARStreak is a laser-guided short-range air-defence missile — among the fastest in the world — that fires three dart-shaped sub-munitions. The Lightweight Multirole Missile (Martlet) engages both air and surface targets, while RAPIDFire is a 40 mm gun system for close air defence and counter-drone work. STARStreak rose to operational prominence against low-altitude threats in the war in Ukraine.

CONTACT, SYNAPS and Syracuse: SYNAPS is Thales’s software-defined military radio family; CONTACT is the next-generation tactical-communications network for France and its partners; and Syracuse is France’s military satellite-communications programme, providing secure, jam-resistant links. Together they form the backbone of modern network-centric warfare. Add the TALIOS targeting pod on the Rafale, the Searchmaster maritime-patrol radar and the FlytX cockpit, and the breadth of the catalogue becomes clear.

Who Operates Thales Systems?

Who Are Thales’s Competitors?

Because its portfolio is so broad, Thales meets different rivals in each sub-market. In radar and sensors its main competitors are Germany’s Hensoldt, Sweden’s Saab, Italy’s Leonardo, Israel’s IAI/ELTA and America’s RTX (Raytheon). In naval systems it competes with Leonardo, Saab and Lockheed Martin. In air defence it faces MBDA, Rheinmetall, Diehl Defence, Norway’s Kongsberg and, again, RTX. In cyber and digital defence its rivals include BAE Systems, Leonardo, Northrop Grumman, L3Harris and Airbus Defence and Space.

Thales and Türkiye

Thales has been present in Türkiye for more than 40 years, employing over 350 people across sites in Istanbul and Ankara and operating two local engineering companies: Yaltes in defence and Thales Ulaşım in ground transportation. According to open sources, its principal defence activities in Türkiye have included the TRS-22XX radars, the mission systems of the Meltem maritime-patrol aircraft, the GENESIS combat-management system and SMART-S naval radars.

The most striking feature of the relationship is that it has evolved from a one-way sale into a reciprocal supply partnership: Thales buys the transmit/receive (T/R) modules used in its SMART-S Mk2 radars from the Turkish defence-electronics champion ASELSAN, with deliveries of the first 100 modules starting in 2015. At the same time, Türkiye’s recent push into indigenous air-defence and sensor capability — through programmes such as HİSAR, SİPER and ASELSAN’s own radars — increasingly confronts suppliers like Thales with home-grown competition in the Turkish market.

Strengths and Weaknesses

Strengths: deep expertise in defence electronics; an unusually broad radar, sonar and sensor portfolio; an entrenched position in NATO and European programmes; multinational scale in cyber and space; and a wide export network. Weaknesses and risks: as a non-builder of large platforms, Thales often remains a subcontractor; it is dependent on French political decisions and export licences; it faces the scale advantage of U.S. giants such as RTX, Lockheed Martin and Northrop Grumman; and it must contend with fierce competition and rising localisation by customer states in radar and air defence.
