I admit, I am thinking ahead of the curve but it is better to be safe than sorry.
Did you see this ?
A Russian submarine has sunk off the shores of Russia’s Far Eastern Kamchatka peninsula...
The written-off vessel was being towed to China where it would be cut for metal scrap. Passing the Kuriles, the sub gave a lurch and started to sink. The crew decided to return to the port of Petropavlovsk, but could not lead the sub to the shore. The vessel sank with no people aboard.
The sub, which was the property of a private company, had been dismantled several years ago.
Three years ago, nine of ten crew aboard died when a Russian nuclear sub sank in the Barents Sea during towing.

"Iranians do not have a sub now, "
I am sorry, but I totally disagree. Especially after seeing pictures of the president of Iran standing on it.
