The move comes just days after North Korea demonstrated a significant leap forward in their missile program after launching a projectile that achieved "successful" controlled reentry into the Earth's lower atmosphere rather than falling back to the surface, according to a preliminary U.S. intelligence analysis, two U.S. officials tell CNN.
The USS Ronald Reagan departed for the Korean Peninsula on Tuesday after completing a maintenance period and sea trials in its homeport of Yokosuka, Japan, according to the Navy.
"Coming out of a long in-port maintenance period we have to ensure that Ronald Reagan and the remainder of the strike group are integrated properly as we move forward," Rear Adm. Charles Williams said in a press release.

Defense officials would not comment on long the two carriers would be there, but ultimately the Reagan is expected to replace the Vinson in the region once its deployment ends.
The 1,092-foot Reagan, a Nimitz-class carrier, has a crew of 4,539 and is equipped with roughly 60 aircraft, according to the Navy. It was commissioned in 2003 and cost about $8.5 billion.
The USS Carl Vinson, also a Nimitz-class carrier, arrived at the Korean Peninsula late last month as a show of force in advance of a long-anticipated sixth nuclear test from the North Korean government.
