SEG projects in the Maritime domain have involved entire systems or selected subsystems of Ships, Submarines, Unmanned Underwater Vehicles (UUVs), and Electronics [examples are EW, ECM, sonar, and Command, Control, Communication, Computer, Intelligence, Surveillance, and Reconnaissance (C4ISR) elements].

The table provides an overview of projects for which Maritime is the 'primary' domain. Project names link to the corresponding project write-ups and a brief description of the SEG role.

Cost Estimation Framework for Naval Capability Assessement (NCA)


Program Description: The program was an initiative to conduct path-finding research into “cost of capability” analysis required as part of the Joint Capabilities Integration and Development System (JCIDS).  The effort was focused on capturing capability “costs” associated with mission level modeling and simulation.

SEG Role: SEG provided cost, systems engineering, and operations research support to the NCA program. Specific efforts included developing the cost analysis framework and mappings to warfighting metrics to allow accumulation of the “costs”.  “Cost” in this context created unique problems that biased results toward legacy systems and/or single mission systems.  SEG pioneered the concept of using Life Cycle Cost (includes Research, Development, Test & Evaluation (RDT&E), Procurement, and Operations and Support (O&S)) amortized over the projected lifetime operating hours for a system to yield LCC$/hr used in the capability costing.  The concept was further refined to allocate a fraction of the LCC$/hr as a function of the percentage of the system life cycle allocated to the capability being assessed.

Hybrid Multi-Material Rotor (HMMR)


Program Description: HMMR will enable revolutionary advances for the rapid development and demonstration of lightweight, high-performance multi-material rotors for current and future US Navy Submarine applications. The ultimate goal is to develop and demonstrate multi-physics performance prediction tools and multi-material manufacturing processes that can be successfully transitioned to the US Navy to improve performance and reduce weight and development costs of current and next-generation submarine rotors. A large percentage of the acquisition cost of legacy US Navy submarine rotors is associated with non-recurring design, analysis, test and evaluation iterations required to demonstrate the performance of the rotor. These rotors are designed to simultaneously address multiple demanding maritime operational environment requirements using proprietary, uncoupled special-purpose domain codes (e.g., structural and hydrodynamic codes). The current uncoupled nature of these legacy tool-sets is considered to be an impediment to shortening the rotor design cycle due to their inability to rapidly and accurately predict rotor off-design performance (e.g., during standard maneuvers, crash-back, backing and crash-ahead operations).

SEG Role: SEG provides cost and systems engineering support to the HMMR program. Specific efforts include review and analysis of software design documentation, creation of ground rules and assumptions for the LCC efforts, and program design milestone support.

Tactical Relay Information Network (TRITON)


Program Description: The overall objective of TRITON is to provide a field quality, Technology Readiness Level 6 (TRL-6) submarine laser communication system that operates in the blue spectrum. The intent is to validate the significant improvement blue laser technology brings to submarine laser communications (SLC) at speed and depth; specifically, in meeting, or exceeding, the Navy's specified downlink communication requirements for Anti-Submarine Warfare (ASW) operations. This effort will leverage a number of the previously demonstrated SLC technologies, including Cesium Atomic Line Filters, solid-state lasers (SSLs) and forward error correction coding. more information

SEG Role: SEG provides cost, systems engineering, and source selection support to the TRITON program. Specific efforts include

1. Monthly earned value management review and feedback to contractor teams
2. Budget analysis and support
3. Schedule and cost analysis of programmatic delays/ changes
4. Review and analysis of proposal packages
5. Supporting contract specialist through negotiation and award

UUV New Starts

UUV New Starts

Program Description: DARPA Defense Sciences Office (DSO) was exploring various small to medium size UUVs for further development.

SEG Role: SEG provided cost and systems engineering support to the UUV programs. SEG researched various representative technical, programmatic, cost, etc. parameters to create some scaling metrics for formulating multi-year budgets to support phased execution of several potential ‘new start’ UUV programs.
