MANILA, Philippines ? The nuclear-powered aircraft carrier USS George Washington and its escort warships are scheduled to arrive Saturday morning in Manila for a four-day goodwill visit.

The American carrier group's port call aims to "further enhance the strong historic ties between the US and the Philippines," according to the US Embassy in Manila.

The 100,000-ton "supercarrier" will be "anchored out in Manila Bay and the only way to gain access to it is through a ferry service," said an embassy media advisory.

During their visit, some of the George Washington's 5,500-plus crew and air wing members will take part in "community relations projects and professional exchanges between the US and Philippine navies."

On August 11 to 15, 2009, the George Washington carrier group made its first goodwill visit to the country.

Meanwhile, the Department of Foreign Affairs (DFA) said Friday the entry here of nuclear-powered foreign vessels "does not violate the Constitution."

DFA spokesman J. Eduardo Malaya clarified "the Constitution prohibits the entry of nuclear weapons but not necessarily nuclear-powered foreign naval vessels." The US government does not say what kinds of armaments its specific ships carry.

Kabataan party-list Representative Raymond Palatino called the visit here of the USS George Washington "another blatant disrespect of our Constitution."

"It's also an insult to the Sept. 16, 1991 Senate vote to reject US bases," Palatino added.
