U.S. Navy Block IV Virginia-class Attack Submarines Ready to Harass Enemy Shipping – The USS Montana, a fast attack Virginia-class Block IV submarine, has been introduced to the navy.
The Montana is almost ready for patrols after passing sea trials earlier this year. Huntington Ingalls Industries produced the 21st Virginia-class sub and this is the third Block IV boat. Ten thousand workers toiled on the submarine for Montana’s production that began in 2015.

The Montana is the third of ten Block IV submarines, and it was originally christened in 2020. Its planned service life is 30-years. The Montana came after the second Block IV sub, USS Oregon, which was delivered last month at General Dynamics Electric Boat.
