### Project 0770 — Adv Sub Supp Equip Prog

A continuing need exists to improve Imaging and Electronic Warfare (EW) support capabilities in view of the advancements in potential imaging counter-detection and the increasingly dense electromagnetic environment caused by the proliferation of complex radar, communications, and navigation equipment of potential adversaries. Improvements are necessary for submarine Imaging and EW to be operationally effective in the following mission areas: Joint Littoral Warfare, Joint Surveillance, Space and Electronic Warfare, Intelligence Collection, Maritime Protection, and Joint Strike. This project will concurrently consider both Imaging and EW domains as improved mast systems are designed. The evaluation of state-of-the-art technology to implement periscope/mast improvements via EW electromagnetic and electro-optic sensors results in improved capability. Engineering Development Models (EDMs) are developed, evaluated, and validated in the lab and through at-sea testing. This project is a non-Acquisition Category (ACAT) program. The test articles identified consist of critical components that will be fully developed during the Engineering Manufacturing and Development phase into EDMs. Software-based capabilities in Imaging and/or EW domains that will process inputs from improved masts may be integrated and tested within this project.

### Project 1739 — Submarine Arctic W/F Development

The Submarine Arctic Warfare Development Project provides the U.S. Navy Submarine Force (SUBFOR) a cadre of trained Arctic Operation Specialists (AOS) and an inventory of unique Arctic sensors that are installed to optimize submarine safety during under-ice operations. AOS personnel assigned from ASL embark on submarines that deploy to the Arctic, cold water and iceberg regions, and marginal ice zones (MIZ) in northern latitudes of the Atlantic and Pacific Oceans and are advisers to the Commanding Officer. ASL is a shore facility at Naval Base Point Loma with the infrastructure capable of supporting personnel and equipment to conduct the submarine Arctic Warfare Development mission. Improvements and life-cycle expenditures to the facility and warehousing are made as necessary to support the mission. The Submarine Arctic Warfare Development Project, via ASL, responds to the increased threat of naval activity in the Arctic regions while continuously supporting the Navy's strategic objective of Assured Access and Combat Credibility. ASL provides a unique capability that enables the SUBFOR to satisfy the requirements laid out in the Arctic Maritime Homeland Defense Initial Capabilities Document (ICD). ASL and SUBFOR demonstrate existing Arctic Warfare capabilities and operational and tactical proficiency while developing advanced submarine technology in unique cold-water environments, in under-ice conditions, and in ice-covered shallow water regions through the Ice Exercise (ICEX) program that includes Operation Ice Camp. ICEX places an emphasis on submarine operability and mission capability in the world's harshest maritime environment. Efforts include assessment of combat system effectiveness, weapons testing, use of High Frequency (HF) sonars in Arctic regions, testing of ice-capable submarine structures, and development of class-specific Arctic operational guidelines. Tactical Development (TACDEV) is conducted biennially and requires up front comprehensive planning and work-up training, as well as post exercise analysis and reporting. ICEX provides the framework for various submarine test and evaluation efforts in Arctic regions and at periodic Ice Camps. The ICEX program represents DoD's only drifting ice station capability through Operation Ice Camp.

## Mission & acquisition strategy

This Program Element (PE) addresses advanced submarine technology areas in support of the Navy's strategic objective of Assured Access and Combat Credibility. All projects funded in this PE are non-Acquisition Category (ACAT) programs. PROJECT 0770 - The Advanced Submarine Support Equipment Program objective is to improve submarine operational effectiveness through the implementation of advanced Research and Development (R&D) efforts focused on advanced Imaging and Electronic Warfare (EW) support.

- This project is a non-Acquisition Category (ACAT) program. - Use Naval Undersea Warfare Centers (NUWC) to provide technical assistance awarded through NAVSEA Reimbursable Work Orders for submarine tracking, communications, and TORPEX capability at the drifting ice camp. - Use sole source and competitively awarded contracts through the U.S. Army Corps of Engineers (USACE) Alaska regional office for ICEX (Operation Ice Camp and ARCEX) logistics, engineering, and operations support. - Use sole source and competitively awarded contracts through the Fleet Logistics Center (FLC) regional contracting office and Defense Logistics Agency (DLA) for equipment procurement and technical services.
