Warships for the SCP Foundation

What ships should the SCP Foundation design for the tasks it faces?

One proposal combines battleship protection, arsenal-ship capacity, and helicopters or F-35Bs, while ordinary tasks continue to use conventional naval equipment.

In the SCP scenario, an anomalous Bismarck needs specialized containment because ordinary modern weapons cannot affect it. Iowa-class battleships monitor it with supercarrier support, and its ability to disappear or relocate gives speed a purpose. The choice of Iowas is questioned because close observation puts them within range, prompting a preference for greater armor. Other accounts of the Foundation include submarines, destroyers, and oceanographic research vessels, with conventional equipment used unless an anomaly requires something unusual. A proposed purpose-built warship combines a battleship, an arsenal ship, and aviation capacity for helicopters and F-35Bs. These are different responses to fictional hazards whose behavior determines which ships can be useful.
