This NAVADMIN addresses the Navys discontinued use of the Digital Nautical Chart (DNC), the submarine specific product MATT, and Tactical Ocean Data (TOD) by fiscal year (FY) 2025 and its transition to the Electronic Navigational Chart (ENC) (using the IHO S-57 data format standard), Submarine ENC, and Additional Military Layers (AML). The adoption of ENC enables the ability to create and display AMLs which overlay additional information on the navigation chart that is not available on paper or DNC. 2. With this transition, AML will replace TOD 0, TOD 4, and anti-submarine warfare (ASW) bathymetry products. NGA will release limited coverage of ENC, SMENC, and AML in FY20 and complete global coverage by FY24. 3. Ships equipped with ENC-approved Electronic Chart Display and Information System (ECDIS) software shall use ENC where and when available, and continue to use DNC where and when ENC is not available. Navy programs relying on DNC for navigational or non-navigational purposes shall plan for DNC termination in FY25. 4. The AML data layer requirements are currently being generated and will include (not all-inclusive) contour line bathymetry; environment, seabed and beach; large bottom objects; maritime foundation and facilities; routes, areas, and limits; and small bottom objects. Commands should submit additional requirements for any other desired information and unmet data display needs as AML requirements to their Type Commander. 5. Released by VADM Jeffrey E. Trussler, Deputy Chief of Naval Operations for Information Warfare, OPNAV N2N6.// BT #0001 NNNN UNCLASSIFIED//
