A larger fleet creates more command, executive, senior-rate, and specialist billets, giving trained personnel visible paths to promotion. Comparing a hypothetical 45-ship destroyer, frigate, and submarine force with a much smaller 25-unit fleet shows how sharply career opportunities contract. When sailors expect limited advancement or repeated deployments, leaving in their late twenties becomes rational because retraining is easier then. More hulls also spread deployments across a larger personnel pool, reducing burnout and preserving time for training and family life. Force structure and retention reinforce one another because cuts reduce career depth and make the remaining fleet harder to crew. A larger establishment also absorbs individual departures more easily, whereas losing a few officers can seriously affect a much smaller pool.

Why fleet size affects retention and career depth
More hulls create promotion paths, spread deployments, and retain trained people, while fleet cuts can make crewing problems reinforce themselves.
