France investigates reports of drones over nuclear sub base

French marines fired on five drones over Île Longue naval base, home to nuclear submarines, prompting a military probe amid suspicions of hybrid warfare tactics, officials said.

  • On December 4, French marines opened fire at five unidentified drones detected around 7:30 p.m. over the Île Longue naval base, the Atlantic hub for France's ballistic-missile submarines.
  • The incident follows a wave of similar overflights across Europe, with drone incursions over military sites in Denmark, the Netherlands, and Belgium suspected as Russian hybrid-warfare tactics.
  • The marine infantry battalion launched a search and anti-drone operation, firing multiple anti-drone shots while Liberation reported the drones were 'neutralized', though authorities have not confirmed this.
  • The military prosecutor's office in Rennes opened a formal investigation on Friday, and Defence Minister Catherine Vautrin confirmed troops intercepted the overflight while officials said sensitive infrastructure was not threatened and declined to attribute the incident.
  • Security analysts warn the pattern signals hybrid-warfare probing critical infrastructure, with some reports linking launches to Russian-linked cargo ships; Guillaume Le Rasle said, "There are precedents".
