Underwater archaeology took off from 1950 following the invention of the aqualung by two Frenchmen. In 1966, France became the first country with a specialized organization for underwater archaeology (DRASSM (Département des Recherches Archéologiques Subaquatiques et Sous-Marines)). The evolution of French law has provided strong protection for this heritage. Over the last 40 years, DRASSM has identified several thousands of wrecks and has managed the excavation of many of them. Currently, DRASSM has been given a new lease of life, with a service enhanced by young recruits, new buildings, and a technologically advanced research vessel.
