ENSTA's history

ENSTA's origins date back to 1741, when Henri-Louis Duhamel du Monceau, Inspector General of the French Navy, identified the need to provide master shipwrights with theoretical knowledge in mathematics and physics. After initially being established in Toulon, the school was transferred to Paris and set up in the Louvre Palace.

In 1765, after a seven-year hiatus due to budgetary reasons, Duhamel du Monceau secured the reopening of the school and ran it until the end of his life. It gradually became the École Nationale Supérieure du Génie Maritime (National Graduate School of Marine Engineering).

On April 17, 1819, Baron Portal, Louis XVIII's Minister of the French Navy, created special petty officer schools in Brest, Rochefort, and Toulon. These schools trained highly skilled workers in the practical methods of the arts related to naval architecture.

In 1868, these schools were reorganized into two levels: preparatory schools and normal schools for ships' officers. In 1877, the Brest school became the École Supérieure de Maistrance (Higher School for Ship's Officers).

The Commission des Titres d'Ingénieur (CTI), created in 1934, accredited the "École Nationale Supérieure du Génie Maritime" and the "École Supérieure de Maistrance" to award engineering degrees equivalent to an MSc in Engineering.

In 1940, the École Nationale Supérieure du Génie Maritime merged with the École d’Application de l’Artillerie Navale, expanding its areas of expertise.

In 1961, the French Ministerial Delegation for Armament initiated a series of mergers that led to the creation of ENSIETA (National School of Armament Engineering and Technology) in 1971, which later became ENSTA Bretagne. Initially, training was spread between Brest and Arcueil, then fully centralized in Brest in 1987.

At the same time, in 1970, the French Procurement Agency (DGA) merged the École Nationale Supérieure du Génie Maritime (National Graduate School of Marine Engineering) with several other schools to create the École Nationale Supérieure de Techniques Avancées (ENSTA):

• École Nationale Supérieure des Poudres (National School of Powders) (1900)
• École Nationale Supérieure de l'Armement (1936)
• École des Ingénieurs Hydrographes de la Marine.

ENSTA then took on a broader mission to train generalist engineers capable of supporting major transformations in strategic sectors (transport, energy, defense, etc.).

In 1990, ENSIETA opened its entrance exams to civilian students. By 1996, civilians made up the majority of the student body. The school expanded its research activities, inaugurating a research center in 2005 equipped with cutting-edge experimental facilities.

In December 2010, ENSIETA became ENSTA Bretagne when it joined the ENSTA group alongside ENSTA, which was renamed ENSTA Paris for the occasion.

In 2012, ENSTA Paris moved to the Saclay plateau, to premises certified as High Environmental Quality (HQE), near the École Polytechnique.

At the end of 2018, ENSTA Paris joined École Polytechnique, ENSAE Paris, Télécom Paris, and Télécom SudParis to create the Institut Polytechnique de Paris, a world-class teaching and research institution.

On January 1, 2025, ENSTA Paris and ENSTA Bretagne merged to form a single institution, ENSTA. It brings together 2,200 students, 670 staff, including nearly 200 teachers and teacher-researchers, 300 doctoral students, 11 research laboratories, and some 30 joint chairs and laboratories spread across its two campuses in Paris-Saclay in Palaiseau (Île-de-France) and Brest (Brittany).

ENSTA provides training and conducts research in the areas of defense and security, sustainable energy, transport and mobility, engineering for health, naval engineering, and digital technology. Its alumni community now forms a vast network of nearly 20,000 former students.
