The tanker opportunity cost of a modern battlecruiser

How many tanker ships might cost the same as one modern battlecruiser?

Roughly four or five, although the figure is an estimate rather than a detailed cost calculation.

The rough estimate is that the cost of a modern battlecruiser could buy four or five tankers. Battlecruisers and battleships were multimillion-pound assets. The comparison shows how much logistical capacity could be sacrificed when money is concentrated in one capital ship. The figure is an on-stream estimate rather than a worked procurement calculation, so the opportunity-cost lesson matters more than the exact ratio.
