Electronic Support Measures (ESM) describe the division of electronic warfare involving actions taken under direct control of an operational commander to detect, intercept, identify, locate, record, and/or analyze sources of radiated electromagnetic energy for the purposes of immediate threat recognition (such as warning that fire control RADAR has locked on a combat vehicle, ship, or aircraft) or longer-term operational planning. ESM gathers intelligence through passive "listening" to electromagnetic radiations of military interest. ESM systems provide automatic threat detection and warning for platform self-protection, situational awareness including emitter identification to support tactical decisions and indications of possible hostile intentions. When used in conjunction with radar systems, they can identify the source and assist determining bearing, range and track dynamics.
SEA1448 Phase 4A is a project to provide the ANZAC Class Frigates with an improved Tactical Electronic Support (ES) Capability by replacing the existing ANZAC CENTAUR Electronic Support (ES) system with a system based on the Exelis ES-3701. SEA 1448 Phase 4A is one of the RAN's highest priority projects. It received Second Pass Approval in February 2013 and a contract with Exelis was signed on 26 March 2013.
The ES-3701 provide excellent direction finding accuracy while operating in high density environments. The flexible architecture has allowed the system to match emerging threats.
Leading up to Second Pass approval the project conducted a number of risk reduction activities so that contractors (such as Exelis, SAAB, BAE Systems, and CEA Technologies) and the Commonwealth (Project SEA 1448 Phase 4A and the ANZAC Ship SPO) could scope and cost the program, consider options, and determine risks.
This presentation will discuss the approach and the outcomes of conducting the Risk Reduction Activities as part of the 1st to 2nd Pass activities and how it assisted the progress of the project post Second Pass approval.
