Did the Obama administration perform any "show of force" moves on North Korea?

Question

A U.S navy strike group has been deployed to move towards the Korean peninsula as a show of force

A U.S. Navy strike group will be moving toward the western Pacific Ocean near the Korean peninsula as a show of force, a U.S. official told Reuters on Saturday, as concerns grow about North Korea's advancing weapons program.

with North Korea responding:

"We will take the toughest counteraction against the provocateurs in order to defend ourselves by powerful force of arms," the foreign ministry spokesman said.

"We will hold the US wholly accountable for the catastrophic consequences to be entailed by its outrageous actions."

Question: are there any instances of the Obama administration doing the same "show of force" moves on North Korea?

Note: To define what I mean by "show of force moves": any political sanctions or military deployments with the intention of intimidating North Korea.

Answer 1

Since 1976 there has been an annual military exercise known as Foal Eagle (formerly known as Team Spirit) that has taken place in the Korean area. One of its primary purposes is to be a show of force to the North Koreans. It involves large scale naval and amphibious maneuvers with both American and South Korean forces. It has gone on ever year (with the exception of a short stretch from 1994 to 1996), so every president since Carter has presided over these exercises.

This military exercise also draws out a (generally aggressive and threatening) response from North Korea, to which the States will frequently respond to with even larger shows of force (IE sailing an aircraft carrier through the area, or flying some bombers overhead). Thus far there has been no actual shooting or deaths in these moments.
