Can someone page Sean Connery’s son? Because it seems like the time to start casting a new movie about Russian submarines. Except this time the submarine’s story can probably be told in a one-minute commercial—a spectacular, flame-filled commercial.

On Tuesday evening, Ukraine launched an attack against drydocks associated with the naval port at Sevastopol in Russian-occupied Crimea. In that attack, the Rostov-on-Don, a Kilo-class submarine, was reportedly destroyed. A surface ship, reportedly a Ropucha-class landing ship that has been identified as the Minsk, was also heavily damaged and is also likely to be destroyed.

Unlike Russian attacks on Ukrainian cities, Ukraine used its long-range precision weapons to strike vital interests of the Russian military. And this single attack cost Russia assets worth well over $300 million.
