Saab ADM 401

ADM 401 is Saab's 84 mm Carl-Gustaf area-defence munition for close-in protection. It is cataloged as relationship-only ammunition tied to the Carl-Gustaf launcher family because the specific flechette round is documented by role, payload, and compatibility rather than by independent conflict use.

Effect And Compatibility

ADM 401 is best read as a close-protection round inside the Carl-Gustaf ammunition family: Saab identifies the launcher family, payload, intended target set, and short effective range, but does not present it as a separate conflict-attributed weapon.

Feature	Sourced detail	Reader note
Payload	About 1,100 flechettes.	The round is an anti-personnel area-defence munition rather than a shaped-charge anti-armour round.
Release method	Gas pressure releases the flechette payload instead of an explosive charge.	This distinguishes the effect mechanism from high-explosive Carl-Gustaf ammunition.
Intended targets	Troops in the open and soft-skinned vehicles at about 100 m.	The short range places the round in close-in protection use.
Firing weapon	Carl Gustaf recoilless rifle 84 mm family.	Saab describes all 84 mm Carl-Gustaf munitions as compatible with every version of the weapon.
