Cost Analysis for 3D Printed Counter-Unmanned Aerial System (C-UAS) Guided Rocket Prototype

Abstract

Low-cost drone use has become prolific in the ongoing conflicts in Ukraine and in the Red Sea, along with current pacing threat of China. The growing usage of inexpensive unmanned aerial systems (UAS) in military engagements exposes a critical vulnerability of the United States. The United States largely relies on expensive and sophisticated ordnance that have long production lead times. Stockpiles of these munitions are limited and depleting inventories to counter cheaply made threats is unsustainable and creates risks for future military operations. A potential solution is for the United States is to develop its own low-cost rockets that are capable of successfully engaging and downing UAS. USINDOPACOM is currently working on a viable prototype that leverages off-the-shelf parts and 3D printed components that could pave the path for viable alternatives. However, understanding the rockets cost once it can accomplish the desired outcomes is required. This research aims to provide relevant cost information for USINDOPACOM’s prototype rocket with the larger intention of supporting informed strategic decisions for adoption and production of rockets that address the threat created by low-cost UAS. Using both single-variable and multivariable regression analyses, we examine how two key factors – labor hours and range influence the overall cost of these defense systems. Our study strongly supports selecting the multiple regression model to estimate the prototype’s cost.
