More hulls reduce the strategic shock of one loss

If an aviation ship is indispensable but the loss of the only available hull would be strategically crippling, fleet depth is part of the answer. More carriers or carrier-like ships reduce the operational shock of losing one without making casualties any less grave. A successful hit does not automatically destroy an entire crew, and modern damage control may keep a ship afloat long enough for evacuation. Most losses develop through cumulative damage and fire rather than a single perfect strike, although a catastrophic lucky hit remains possible. British losses in the Falklands War illustrate the distinction between losing ships and losing every person aboard them.
