COMBAT SYSTEMS TEST BED (CSTB)
Abstract
Combat Systems Test Bed (CSTB) is an AEGIS Modeling and Simulation (M&S) tool built to conduct high fidelity analysis for AEGIS Developmental Test (DT) and Operational Test (OT) that DOT&E highlighted in previous AEGIS baselines. CSTB models AEGIS Combat System (ACS) performance against adversary threats through the use of high-fidelity M&S, generating Objective Quality Evidence (OQE) that directly supports Director, Operational Test and Evaluation (DOT&E) evaluations of new AEGIS baselines. CSTB reduces Navy OT costs by enabling portions of AEGIS operational testing to be conducted via M&S increasing requirements coverage and avoiding the costs of targets and weapons that would ordinarily be required to conduct OT solely via live fire events. In letters dated August 9, 2013 and June 9, 2014, DOT&E has established the requirement that Navy use tactical code-based M&S (CSTB) in conjunction with live tests for AEGIS OT. IWS1 and Commander Operational Test and Evaluation Force (OPT) will continue to use CSTB for AEGIS Baseline 9 and Baseline 10 Critical Operational Issue evaluations in 2023 and beyond. CSTB has also been used extensively to develop pre-flight performance predictions and post-flight performance reconstructions for AEGIS Baseline live fire tests since January 2015. During this time, CSTB has established a track record of accurate predictions over 185,000 missile scenarios - identifying mission-critical software defects that led directly to $584M in cost avoidance and precluded numerous flight test failures. In addition to its support for AEGIS BL9/10 OT and flight test predictions, CSTB is also critical to Frigate (FFG) Combat System and Integrated Combat System Development. CSTB end to end Hard Kill capabilities are available to SM-2 missile models to support BL9 testing. Delivery of Hardkill/Software (HK/SK) models are planned to provide additional functionality in support of BL9, BL10, and FFG Combat System testing requirements.
