The Seraphim T3 Submarine Hunter, nicknamed the Yathsou, is a Seraphim unit. It is a submarine unit. It is a dedicated sub-killer. Armed with three torpedo tubes, a pair of torpedo defense systems and an AA auto-cannon for use when surfaced.

The Yathsou is arguably the most powerful ship-to-ship combat unit in the game, being affordable enough to mass-produce in sufficient numbers to overwhelm more powerful vessels like the experimental Atlantis, Tempest or Megalith and powerful enough to dominate cheaper T2 submarine hunters such as the Vesper or Barracuda...it is even a perfect counter for experimentals trying to cross water. All in all, the Yathsou is probably the reason the Seraphim lack an experimental naval unit.

Being submersible gives it all the advantages over the UEF Neptune Class, which has most of its power concentrated in its surface-only Plasma Cannons, but when the Yathsou surfaces its Losaare AA Autocannon is devastating against air units, including Torpedo Bombers. Enough Yathsous can effectively guarantee naval superiority. Its only weaknesses are its inability to bombard units on land or hovering above the water surface, and its long build time (despite its low cost). Yathsous are perfect escorts to the Fatboy or Monkeylord crossing water. Also, a counter intel boat will prevent these from revealing the Monkey's position.
