How is USS Charlotte?
- USS Charlotte is America’s advanced Los Angeles class nuclear fueled submarine. It was inducted into service in the 1990s and is counted among the deadliest submarines of the US Navy.
- This submarine runs on nuclear energy, so it can stay in the sea for months without coming to the surface. Its maximum speed is believed to be around 55 km/h and it is designed to operate very quietly in the deep sea.
- The USS Charlotte typically has a crew of more than 130 and is equipped with torpedoes, cruise missiles and modern sonar systems. Weapons like MK-48 torpedoes are specifically designed to destroy large warships and submarines.
- US Defense Secretary Pete Hegseth confirmed the attack, saying that the Iranian ship thought it was safe in international waters, but American torpedoes sank it.
- IRIS Dena was returning to Iran after participating in the Milan Multilateral Naval Exercise organized in India.
Why were Australian soldiers in the submarine?
After this incident another important revelation came. Australian Prime Minister Anthony Albanese confirmed that three Australian military personnel were also present on the US submarine at the time of the attack. Albanese said that these soldiers were deployed on the submarine as part of a training program under the AUKUS defense agreement. He said, ‘I can confirm that there were three Australian personnel on that submarine, but no Australian took part in any aggressive action against Iran.’
Such a program has been going on between Australia and America for a long time, in which Australian marines undergo training on American submarines. Its purpose is to prepare Australia to operate nuclear-powered submarines in the future.
