Why a Coast Guard label cannot hide a capital ship

Calling a warship a Coast Guard vessel would not remove it from treaty tonnage, although negotiated categories could protect genuine patrol craft and sloops.

Question

Could the United States evade the Washington treaty by building a Coast Guard capital ship?

Short answer

No; the ship would still count, while genuine Coast Guard patrol vessels required explicit treaty-category allowances.

Notes

A Coast Guard capital ship would still count against the treaty's capital-ship allowance. Changing the service label does not change the vessel's size, armament, or military function. The United States instead needed treaty language that allowed its Coast Guard and comparable patrol duties to continue. Distinctions for sloops and similar vessels were negotiated openly rather than created by disguising a battleship. Treaty compliance depends on the agreed technical category rather than the name painted on the organization.
