The Montcalm is a F70 type anti-submarine frigate of the French Marine Nationale. She is the fourth French vessel named after the 18th century Marshal marquess Louis de Montcalm de Saint Véran (see French ship Montcalm for the others).

There are seven ships in the F70 class :

D640 Georges Leygues
D641 Dupleix
D642 Montcalm
D643 Jean de Vienne
D644 Primauguet
D645 La Motte Picquet
D646 Latouche-Tréville

Note: The French navy doesn't use the term "destroyer" for its ships; hence some large ships, referred to as "frigates", are registered as destroyers.
