which submarine sank the iranian ship

The Pentagon has confirmed that a U.S. Navy fast‑attack submarine sank the Iranian warship IRIS Dena in the Indian Ocean using a single Mk‑48 heavyweight torpedo, but the U.S. has not publicly disclosed which specific submarine carried out the attack.

Because your request is formatted like a Quick Scoop / forum-style post, here’s a structured, SEO‑friendly rundown.

Which Submarine Sank the Iranian Ship?

Quick Answer

  • The ship that was sunk: IRIS Dena , a Moudge‑class Iranian frigate.
  • Where it happened: Indian Ocean , off the southern coast of Sri Lanka, in international waters.
  • What hit it: A single U.S. Mk‑48 torpedo launched by a U.S. Navy fast‑attack submarine.
  • Crucial detail: The U.S. government has kept the submarine’s name classified for operational security , so no credible source names the exact boat.

So the honest, complete answer to “which submarine sank the Iranian ship?” is:

A United States Navy fast‑attack submarine fired a Mk‑48 torpedo that sank the Iranian frigate IRIS Dena, but its specific name and hull number have not been made public.

What We Know So Far

The Incident

  • U.S. officials stated that a U.S. fast‑attack submarine engaged IRIS Dena as it transited the Indian Ocean after taking part in exercises in the Bay of Bengal.
  • The torpedo strike reportedly hit near the stern, lifting the ship out of the water in footage released by the Pentagon before it sank.
  • Sri Lankan authorities, who responded to the distress call, reported around 180 people aboard , with dozens confirmed dead and several dozen rescued.

Why the Sub’s Identity Is Secret

  • U.S. defense officials explicitly declined to identify the submarine, citing operational security around submarine movements and tactics.
  • This is standard practice: attack submarine identities during live combat or sensitive patrols are usually classified or withheld.

Because of that, any post, tweet, or forum comment naming a specific boat (for example, guessing a Virginia‑class or Los Angeles‑class hull) is speculation , not confirmed fact.

Forum & “Trending Topic” Angle

This event is trending because:

  • It’s described as the first sinking of an enemy warship by a U.S. submarine with a torpedo since World War II.
  • It comes amid a wider U.S. and allied campaign targeting Iranian naval and missile assets across the region.

You’ll likely see discussion threads debating:

  • Which class of submarine was most likely involved (many point to Virginia‑class or late Los Angeles‑class boats based on where they usually deploy, but this remains unconfirmed speculation).
  • Whether releasing periscope footage without naming the submarine is meant as a deterrent signal to Iran and other actors.

If you’re writing a post, a neutral way to phrase it is:

“Current open sources agree that an unnamed U.S. fast‑attack submarine sank the Iranian frigate IRIS Dena in the Indian Ocean with a single Mk‑48 torpedo; Washington has not revealed which submarine carried out the strike.”
