At 2,895 long tons, the class raises an awkward question about how later naval treaties classified flotilla leaders. First World War-era destroyer leaders could approach 3,000 tons, even though their operational purpose remained tied to destroyer forces. By the Second World War, a vessel of that size would consume scarce cruiser tonnage under treaty limits. The comparison shows how legal categories could diverge from a ship's practical role and design lineage.

When a destroyer leader counted as a cruiser
The Sentinel class's roughly 3,000-ton displacement exposes the awkward boundary between destroyer leaders and treaty-counted cruisers.
