The move was planned before the fall of the Assad regime, an official said.
Rebel forces in Syria captured the capital Damascus and toppled the regime of President Bashar Assad in a lightning-quick advance across the country.
Meanwhile, the ceasefire in Lebanon is holding despite ongoing Israeli airstrikes on Hezbollah targets, which Israeli officials say are responses to ceasefire violations by the Iranian-backed militant group. The Israel Defense Forces continues its intense airstrike and ground campaigns in Gaza.
Tensions also remain high between Israel and Iran after tit-for-tat long-range strikes in recent months and threats of further military action from both sides.
The USS Harry S. Truman aircraft carrier strike group has arrived in the Middle East, according to U.S. Central Command.
The move from the Mediterranean was planned before the fall of the Assad regime in Syria, a U.S. official told ABC News.
The Truman replaces the USS Abraham Lincoln, which left the region last month.

At least 46 people have been killed in Gaza in the last 24 hours according to the Gaza Ministry of Health in the Hamas-run territory.
The expulsion of residents from the northern part of the strip continues amid Israel's intense offensive operation there, the Gaza Civil Defense reported.
The body said people sheltering at a school in Beit Hanoun -- on the northeastern tip of Gaza close to areas of intense fighting like Beit Lahia and Jabalia -- were forced to leave on Sunday morning, with young men arrested.
The Israel Defense Forces said in a statement that its troops "conducted a targeted raid on a terrorist meeting point in the Beit Hanoun area."
In coordination with warplanes, "the troops struck dozens of terrorists from both the air and ground and additional terrorists were apprehended," the IDF said.

Escalating clashes between Palestinian Authority security forces and militants in the West Bank city of Jenin overnight left multiple civilians injured and at least one fighter killed, according to four local sources.
PA forces are seeking to "eradicate sedition and chaos" according to local media citing a PA spokesperson. But Jenin residents and local journalists reported unarmed crowds being targeted by tear gas and gunfire amid protests over the security forces actions.
Locals told ABC News that the PA operation -- which is coordinated with Israel -- has been ongoing for five days, besieging a refugee camp in the city.

The Syrian Observatory for Human Rights monitoring group reported 75 Israeli airstrikes across Syria overnight Saturday into Sunday, bringing its total tally since the fall of former president Bashar Assad to around 453.
The renewed strikes come despite an appeal by Ahmed al-Sharaa -- the leader of victorious rebel group Hayat Tahrir al-Sham, who is also known by his "nom de guerre" Abu Mohammed al-Jolani -- for calm.
Sharaa said HTS and the Syrian transitional government have no interest in being dragged into a new conflict, calling on the international community to pressure Israel to stop its attacks inside Syria. Israel's justification for its strikes, Sharaa said, are now "weak."
