A comparative analysis of contemporary 155 mm artillery projectiles

Abstract

Purpose To recover the growing deficit between American and near-peer mobile artillery ranges, the US Army is exploring the use of the M982 Excalibur munition, a family of long-range precision projectiles. This paper aims to analyze the effectiveness of the M982 in comparison to the M795 and M549A1 projectiles to further the understanding of what this new asset contributes. Design/methodology/approach Based upon doctrinal scenarios for target destruction, a statistical analysis is performed using Monte Carlo simulation to identify a likely probability of kill ratio for the M982. A values-based hierarchical modeling approach is then used to differentiate the M982 from similar-type projectiles quantitatively in terms of several different attributes. Finally, sensitivity analyzes are presented for each of the value attributes, to identify areas where measures may lack robustness in precision. Findings Based upon a set of seven value measures, such as maximum range, effective range, the expected number of rounds to destroy a target, and the unit cost of a munition, the M982 1a-2 was found to be best suited for engaging point and small area targets. It is noted, however, that the M795 and M549A1 projectiles are likely better munition options for large area targets. Hence, an integrated targeting plan may best optimize the force’s weapon systems against a near-peer adversary. Originality/value The findings provide initial evidence that doctrinal adjustments in how the Army uses its artillery systems may be beneficial in facing near-peer adversaries. In addition, the values-based modeling approach offered in this research provides a framework for which similar technological advances may be examined.

Estimation of stresses on 155mm artillery projectiles during launch phase using numerical simulations

“…Brady and Goethals [6] suggest that the 155mm M795 and M549A1 projectiles are better munition options for large area targets, while the PGP 155mm Excalibur M982 was found to be best suited for engaging point and small area targets of higher value.…”

Design and Development of Unmanned Aerial Vehicle (UAV) Directed Artillery Prototype for Defense Application

“…Aerial Reconnaissance and missile guidance with GPS precision are finding an increased use over the past few decades with applications ranging from the recent sophisticated long range satellite guided missile systems such as the M982 Excalibur 155mm artillery projectiles which are recently being used by the US military [1], to small drones being deployed by the local police for surveillance and patrol [2]. Our concept is more or less similar to satellite-based missile launching systems, but instead of using satellites here a UAV is deployed to do aerial Reconnaissance.…”
