Argentine destroyer that led war against Britain sinks, a symbol of decay for once-proud navy

Argentine destroyer ARA Santisima Trinidad lies on its side at the naval base in Puerto Belgrano, Argentina, Tuesday, Jan. 22, 2013. The government is seeking an explanation from the partial sinking of the Navy destroyer that fought in the war against Britain over the Falkland Islands. The ship began leaning three days ago in Puerto Belgrado, about 700 kilometers or 435 miles south of Buenos Aires. At present the sandy bottom in the shallow water is preventing its total collapse.

Argentina's defense chief says he's ashamed over the sinking of a mothballed Navy destroyer, an incident that critics say reflects the abandonment of a once-proud fleet.

The ARA Trinidad led Argentina's 1982 sea war against Britain, but has long been used for spare parts.

The Navy said a broken pipe flooded the ship, but Defense Minister Arturo Puricelli says he suspects negligence or sabotage, and denies that budget cuts are to blame.

Puricelli told Radio 10 on Wednesday that "When the president asks me, I'll be ashamed, frankly, to tell her that a boat sank while tied to the dock."

Opposition congressmen blamed years of disinvestment that they said has left Argentina ill-equipped to defend its seas and sovereignty.
