Reference excerpt

Safran Electronics & Defense, formerly known as Sagem Défense Sécurité, is a French company specializing in optronics, avionics and electronic systems, as well as software for civil and military applications in the naval, aeronautical and space sectors. It is one of the ten entities that make up the Safran Group.

History The Société d’applications générales d’électricité et de mécanique (SAGEM) was created in 1925. The company's products ranged from inertial navigation systems to fax machines. SAGEM also manufactured precision equipment for the French Navy: gyrocompasses, fire-control units, optronic equipment. In 2005, SAGEM merged with the French company "Société nationale d'étude et de construction de moteurs d'aviation (SNECMA)" to form the Safran Group. Within this framework, SAGEM's activities merged with the company Sagem Défense Sécurité. In 2007, the security applications were separated off and a new company named Sagem Sécurité was created (now called Morpho). The Safran Electronics division was created in 2009, grouping together all Safran's electronic engineers. In 2011, the facility in Tarbes (south-west France), which manufactured components for the Megajoule Laser, was sold to the Alcen Group. The question of whether to merge or exchange activities with the Thales Group was regularly raised between 2004 and 2011. On 1 January 2012, the facility in Fougères (France), formerly Sagem Industries, merged with Sagem Défense Sécurité. In the same year, Thales and Sagem acquired Areva's stake in Sofradir. Sagem owns 50% of this subsidiary which is a European leader in infrared detectors. In July, the two companies announced the creation of OPTROLEAD, a 50/50 joint-venture company working in the field of optronics. In January 2013, the facility in Saint-Pierre-du-Perray (France) became a fully owned subsidiary of Safran Electronics & Defense. The company focuses on designing and manufacturing high-performance optics for space, astronomy, high-power lasers and the semiconductor industry. In 2013, Sagem announced the opening of a factory in Casablanca (Morocco) to produce components for actuators and avionics equipment. On 19 May 2016, all the Group's companies took the name of Safran, and Sagem became Safran Electronics & Defense. At the end of that year, the company grouped together all its R&D and R&T activities in the north-west of Paris on the Éragny site. The company has been headed up by the following directors (in chronological order): Jacques Paccard, Jean-Paul Herteman (appointed in November 2006), Jean-Lin Fournereaux (September 2007), Philippe Petitcolin (June 2011), Bruno Even (May 2013), Martin Sion (June 2015) and Franck Saudo (April 2023). In July 2022, Safran Electronics & Defense announced the acquisition of Orolia group, a company recognized globally for its positioning, navigation and timing (PNT) and related activities, technologies and equipment. In November 2022, it was announced Safran Electronics & Defense had acquired the Cesson-Sévigné-based space sector radio-communication and radio-navigation company, Syrlinks. In 2025, Safran Electronics & Defense and Bharat Electronics Limited (BEL), an Indian defence public sector undertaking, signed a memorandum of understanding (MoU) to establish a joint venture in India for manufacturing, customizing, selling, and maintaining the HAMMER precision-guided air-to-ground munition. On 16 February 2026, BEL approved the Project HAMMER which includes the formation of the joint venture, a 50:50 equity Private Limited Company under the Companies Act 2013. The joint venture will operate a Centre of Excellence that will act as "technology and teaming partner for the manufacturing, supply, maintenance and repair of the Guidance Kit of the HAMMER weapon system". The JV will have a board of four directors two nominated by each BEL and SED. The primary users include the Indian Air Force and the Indian Navy. The partnership was one of the agenda during the bilateral meet between French president Emmanuel Macron and Indian prime minister Narendra Modi.

Organization The company has three divisions: Avionics, Optronics & Defense and Safran Electronics. Today, it has nine facilities in France and twelve subsidiaries spread across four continents.

Activity Safran Electronics & Defense is a technology company that develops civil and military solutions for sea, land, air and space applications. For example, in the field of optronics, the company developed the non-penetrating periscope for the Barracuda submarine, the FELIN system (an integrated infantry soldier combat suite), infrared scope and cameras for helicopters and tanks, as well as the Sperwer and Patroller drone systems. In terms of avionics, the company provides numerous types of equipment, ranging from the electric flight control system for the NH90 helicopter to the information system for the Airbus A380, as well as inertial navigation systems and engine control systems. For the space sector, Safran manufactures high-performance space optics used on satellites such as MeteoSat and Gaia.

Worked examples

Example 1 — a first encounter with Safran Electronics & Defense

Start with the simplest possible case. Write down what Safran Electronics & Defense claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Safran Electronics & Defense before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Safran Electronics & Defense ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Safran Electronics & Defense

In research: Safran Electronics & Defense appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Safran Electronics & Defense in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Safran Electronics & Defense is common in secondary-school and first-year university syllabi. It links to neighbouring topics Avionics companies, Electronics companies of France, French companies established in 2004, so understanding it makes those chapters shorter.
In everyday life: Look for Safran Electronics & Defense outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
