as far as our subs sinking a ship 1 for sure...there is some speculation we had a sub take out one of the Iranian's subs but that is not confirmed

Are we targeting any of their military bases to kill soldiers or is coming later?
How is their military personnel split up? I think a poster said part of their military might switch sides
wondering if their is a lot of soldiers wanting regime change

IRIS Dena is the only confirmed kill by a US sub by torpedo since WW2. HMS Conqueror sank the Belgrano (?) during the Falklands War in 1981. You could include a North Korean mini sub sinking the ROKS Cheonan in 2010 as well though. HMS Conqueror is the only other confirmed nuclear sub to fire and sink an enemy ship during combat.

You know those sailors were happy they were away from home...then BOOM. I am glad we got rid of one of their warships. I also pity the men that got thrown in the drink. Naval warfare is a particularly brutal and merciless type of fight.
Infighting within the regime!

Wow.
Moreover, the Dena was described as "the pride of Iran's Navy." The sailors assigned to the Dena would have been carefully screened and selected for their loyalty to the IR.LMCane said:AgBQ-00 said:bonfarr said:

you don't know that at all
the IRGC Navy is just as ideologically committed as other parts of the IRGC. or at least was before they were all destroyed.
and they weren't just galivanting around South America-
they were heading BACK to the Arabian Gulf from the Indian Ocean after attending an Indian Navy exercise. they could have been prepping to fire on us from behind.

well then they were just as incompetent as the rest of the Iranian military.
because Israel has at least 8 Dolphin class submarines who are likely tracking every Iranian ship they can find.

Iran and Hizbullah have already attacked Cyprus three times
this latest report was an actual attack on Turkey

The probability is increasing of a US SSN joining the very exclusive club, the only member so far being HMS Conqueror, of nuclear powered subs having sunk an enemy warship in combat.https://t.co/YOnHsnNaTd
Sri Lanka is reported as saying they're helping to recover 32 injured from the water but no ships were near. If it was an SSN, this is the first sub sinking a ship since HMS Conqueror during the Falklands War and the most recent since a North Korean mini sub sunk the ROKS Cheonan in 2010.
