First submarine named after Massachusetts joins the Navy fleet

The USS Massachusetts has joined the Navy fleet. Saturday's commissioning ceremony made the submarine the first named after the Bay State. The Navy says the nuclear-powered sub has enhanced stealth, sophisticated surveillance capabilities and special warfare enhancements. It cost $2.8 billion and was christened on May 6, 2023, by the ship’s sponsor, Sheryl Sandberg, the former COO of Meta. The sub’s commanding officer did not say where the sub is headed. A U.S. submarine sank an Iranian warship off the coast of Sri Lanka earlier this month in the war with Iran.
