Solid dots = sourced or within ONI's 2035 horizon; hollowdots = extrapolated trend, 2036–2050 (no official projection). PLAN battle-force ships: US ONI projects 395 / 435 / 475 for 2025 / 2030 / 2035; pre-2015 approximate; 2036–2050 a decelerating trend. USN battle force fell from ~570 (1990) to ~295 today; future per CBO/Navy plans (uncertain). RAN major surface combatants have held ~10–13 since 1990; 2030+ reflects the 2024 Surface Fleet Review plan (toward 26 by 2040, funding uncertain). Different navies count differently — the trajectory is the point.
