The Astraea class enlarged the Apollo concept and added heavier gun and torpedo armament while remaining a second-class protected cruiser. Ten six-pounders and four eighteen-inch torpedo tubes increased the punishment an opponent might absorb even when facing a nominally inferior ship. Their role resembles a British form of risk-fleet thinking: they might not defeat a larger warship, but sinking them would be slow and damaging. Because Britain could afford enough of them for worldwide stations, local presence converted modest individual capability into a strategic obstacle.

The Astraea class develops Apollo's distributed risk-fleet logic
The larger, more heavily armed Astraeas preserved the idea of affordable cruisers whose worldwide presence imposed damage and risk on stronger opponents.
