Above the surface of the water, the newly commissioned USS Massachusetts nuclear submarine doesn’t appear too impressive. It only emerges about 30 feet out of the water with a periscope, a non-descript black skin and not much else.
Underneath, however, the $2.8 billion attack sub is a sight to behold. The brand new underwater war machine is docked in Boston Harbor this weekend inside the Conley Shipping Terminal in South Boston.
“The thing that’s amazing to me is watching it from the end of construction and seeing it built in the shipyard, then taking it out for sea testing and then the other day bringing it into Boston Harbor for the first time was just amazing,” said Commanding Officer Mike Siedsma, a Rochester, NY, native who has been leading the crew for the past 44 months. “I don’t think we’ve brought a sub into Boston Harbor since the 1980s or 1990s…We have one of the most advanced pieces of technology in the military here.”
