The Georges Leygues class ("F70 type") is a type of anti-submarine frigates of the French Navy. They are polyvalent, due to their Exocet and Crotale missile complement, which makes them especially suitable for defence of strategic positions, demonstrations or high sea escorts.
There are seven ships in the class :
- D640 Georges Leygues
- D641 Dupleix
- D642 Montcalm
- D643 Jean de Vienne
- D644 Primauguet
- D645 La Motte Picquet
- D646 Latouche-Tréville
