Fleet size, promotion, and personnel retention

Is the Royal Navy's main personnel problem recruitment or retention?

Both interact: a smaller fleet restricts advancement, while better housing, education, benefits, and reserve flexibility can make naval careers more sustainable.

Fewer ships mean fewer billets and promotion opportunities, which can accelerate departures until the service loses critical mass. Recruitment and retention therefore reinforce one another rather than operating as separate problems. Housing, education, gyms, travel, and family support can partly offset higher civilian salaries. Earlier reserve and half-pay arrangements also let experienced personnel study or handle family needs while remaining available for recall. A sustainable navy needs enough hulls and organizational slack to offer both advancement and a workable life ashore.
