It's Blashill's third straight year as coach of the national team. The Detroit Red Wings coach guided the U.S. to a fifth-place finish in 2017 and a bronze medal last year.
The United States plays its first game against Slovakia on May 10.
Former Pittsburgh Penguins and Buffalo Sabres coach Dan Bylsma and New Jersey Devils coach John Hynes were named assistants, as was Kevin Reiter, the director of player personnel for USA Hockey's National Team Development Program.
"It's terrific to have Jeff back coaching our national team," said Chris Drury, assistant general manager of the New York Rangers who was
named U.S. national team GM
on March 20. "He's an excellent leader and is well-versed on what it takes to be successful on the international stage. We're also fortunate to have a terrific group of assistant coaches and support staff that will represent us well in our ultimate goal of bringing the gold medal home to the United States."
Blashill is 136-145-47 in four seasons with the Red Wings. He guided Grand Rapids of the American Hockey League to the 2013 Calder Cup championship and
agreed to terms
on a two-year contract April 2 to remain in Detroit.
"I've been in this organization for eight years and it has been an unbelievable experience," Blashill said. "I believe our arc is starting to head in the right direction, but we've got a lot of work to do. I'm looking forward to digging into that work so that a year from now we're in a better position than we are right now."
