Evolved Sea-Sparrow Missile (ESSM)

The ESSM was developed to improve the capability of U.S and international ships to defend against advanced supersonic, anti-ship cruise missiles.  WIT is a series of system and subsystem tests used to verify the interface of a missile and the Aegis Weapon System (AWS).  The overall objective of WIT was to verify that the AWS and missile system will perform as required to support future planned firings.  An Inert Operational Missile (IOM) is used to conduct the WIT.  The IOM test verified the interfaces between the AWS computer programs and  the missile, design algorithm implementation, and provided risk reduction prior to at-sea testing.  Testing was conducted in-port and at-sea to ensure the shipboard portion of the AWS System was ready to support the ESSM mission.  Major components of the system were tested on an end-to-end basis to ensure that the AWS system performed in accordance with specifications.

 

As a member of the analysis team responsible for ESSM IOM and WIT Assessment, SSTi performed on-site Aegis Weapon System (AWS) analysis of performance of ESSM engagements.  As a result of the team's findings, computer program fixes will be developed to support mission critical system requirements.  The ESSM WIT test phase will culminate in Risk Reduction firings DT/OT firings.
