The Mortier de 81mm léger long renforcé (LLR 81 mm) is a mortar used by the French Army, manufactured by Thales.

Introduced in 1997, it is the latest iteration of the TDA 81 mm light mortar family.

Since then, three variants have been fielded: The LLR 81mm is composed of a base plate, a barrel comprising the breech, and a bipod.

[3] The LLR 81mm can be parachuted either piece by piece, in a kit comprising a dismantled weapon and ammunition, or in larger crates comprising several weapons.

The barrel was reinforced so as to allow firing of all existing 81 mm mortar ammunition.
