57th Anniversary of the Korean Armistice Coincides with Joint US-South Korean Naval Exercise

A joint drill with U.S. forces off the east coast of South Korea on Tuesday featured naval cannons fired from ships and the dropping of depth charges.

Warships fired weapons and dropped anti-submarine bombs in the Sea of Japan during the third day of the four-day exercise, South Korean Defense officials say. They say the target was an abandoned submarine meant to simulate a submerged North Korean vessel. It is part of the largest show of force in the region jointly by the U.S. and South Korea in a number of years.

On the 57th anniversary of the armistice that ended the Korean War, U.S. and South Korean ships intensified high-profile military exercises Tuesday that underscore rising tensions in a region yet to truly find peace.

The massive maneuvers, called "Invincible Spirit," are being conducted by an armada of South Korean and U.S. ships — including the USS George Washington supercarrier — in international waters off the South Korean coast.
