US Army's MCoE evaluates disposable SLIM solution

03 February 2017

Key Points

  • SLIM is intended as a potential solution for the US Army's prospective Individual Assault Munition requirement
  • Calibre and TRL status has not been disclosed

The US Army's Maneuver Centre of Excellence (MCoE) is evaluating a new disposable shoulder-launched rocket concept as one of the participating technologies in the Army Expeditionary Warrior Experiments 2018 (AEWE 2018) initiative at Fort Benning, Georgia.

Designed and manufactured by Aerojet Rocketdyne, the Shoulder Launched Individual Munition (SLIM) is described in the AEWE 18 Technology Systems Book as 'a lightweight, fire from enclosure, ballistic guided, disposable rocket system, equipped with a multipurpose warhead. Weighing 14.9 lb (6.75 kg) and less than a metre (36 inches/91.4 cm) in length (in both carry and firing configuration) SLIM is a point and shoot system intended for engagement ranges of between 15 m and 400 m. Accuracy is illustrated as 90% Probability of Hit at 200 m.

SLIM is designed to engage targets from within structures, without inflicting hearing or respiratory damage to the shooter; it's given target set includes light armour, adobe, brick and concrete structures and bunkers, and troops (using airburst mode).

The calibre of the system has not been disclosed, nor has its current Technology Readiness Level (TRL) status. Aerojet Rocketdyne declined to comment on the SLIM development.

Results from the evaluation of SLIM and other shoulder-launched munitions are expected to inform the selection process for the US Army's future Individual Assault Munition (IAM) capabilities development document.

The IAM is the prospective next-generation, disposable, confined space shoulder launched munition intended to provide an over matching lethality against light armour, hardened targets and field fortifications in urban and complex terrain. According to the US Army, the IAM "will combine all the best capabilities of the M72 LAW, M136 AT4, M136E1 and M141 BDM [Bunker Defeat Munition] and replace them in the Army arsenal."
