The document discusses optimizing enlisted career paths and sea-shore flow (SSF) by determining optimal sea tour lengths based on factors like enlisted community EPA, continuation rates, and gain distributions rather than using sea-shore billet ratios. SSF provides more predictable career paths for sailors, incentives for time at sea, improved geographic stability, and helps ensure the right experience levels and mix of work within the Navy. The Navy has learned sea-shore rotation is not accurate for a sea-centric force and SSF can improve FIT by potentially shortening some first sea tours.

Evolution of Sea Shore Flow None … Close Enough … Optimal Seavey Shorevey Sea Shore Rotation Sea Shore Flow TACOMA CLASS (PF-3) 900 Ship Navy – 775K Personnel Policy: 1957 – 1974 Sailors remained at sea indefinitely and rolled ashore based on time in grade and shore billet availability Catalyst: Centralized Distribution -Previous decentralized system caused large scale “bottle necks” in moving inventory across the Navy - First computer based “fair share” personnel assignment system - Sea Survey and Shore Survey rotation program O.H. PERRY CLASS (FFG-7) 600 Ship Navy – 600K Personnel Policy: 1974 – 2008 Sailors’ sea tour length determined by a ratio of sea billets to shore billets for each particular rating and paygrade Catalyst: All Volunteer Force - Fixed PRD required to calculate inventory projections - Predictable sea tour lengths needed to recruit and retain volunteer Sailors - Sea-shore billet ratio provided a close enough approximation for tour lengths FREEDOM CLASS (LCS-1) 313 Ship Navy – 322K Personnel Policy: 2008 – 20XX Sailors’ sea tour length determined by an optimal career path for each enlisted community Catalyst: Sea-Centric Force - Reduced shore billet structure driven by fiscal constraints - SSR billet ratio metric lacks fidelity needed to manage a sea-centric force - SSF provides optimal sea tour lengths

Sea Shore Flow Obtaining Desired FIT GM Sea Shore Rotation Solution GM Sea Shore Flow Solution Optimal Sea Shore Flow Driven by Fleet Requirements Long First Sea Tour: - Large portion of the sea billets are filled by Sailors on their first Sea Tour - Subsequent sea tours can be shorter than currently prescribed by SSR policy - Meets Fill not FIT Shorter First Sea Tour: - Sea billets manned by Sailors with appropriate experience level - Distributes the sea billets and tour lengths more uniformly over 30 years - Meets Fill and FIT
