The Hauthuum can hold 5 strategic missiles while regular strategic missile submarines can only carry 3, though if it is to be used as a strategic missile launcher, it doesn't have the advantage of submersibility and is a high-profile unit compared to strategic missile submarines. A powerful unit, it can annihilate a T1 fleet, cause serious casualties to a T2 fleet, a base near the water, or severely damage a T3 task force. It has poor AA and no defense against submarines.
