Five naval vessels have served in the Royal French Navy (French: [[:fr:Histoire de la marine française de Richelieu à Louis XIV|Marine Royale Française]]), the French Navy of the Republic (French: [[:fr:Histoire de la marine française depuis 1789|Marine de la République]]), the French Imperial Navy (French: [[:fr:Histoire de la marine française depuis 1789|Marine Impériale Française]]) and French Navy (French: Marine nationale française) have been named Indomptable:
The destroyer L'Indomptable, launched in 1934, was the first to carry the insignia of the French Foreign Legion. The ship's first commander asked Général Paul-Frédéric Rollet to have the Legion as the ship's patron and guardian. The fanion of L'Indomptable was green and red, with the cannons depicted carrying the words "Magenta", "Camerone", "Tuyen Quang", and "Laffaux" (after the battles of Magenta, Camarón, Tuyên Quang and the Aisne – four engagements in which the Legion distinguished itself), and displaying the Legion's grenade as an insignia. The nuclear ballistic missile submarine Indomptable launched in 1974 continued the association.
