Opposition congressmen blamed a decade of disinvestment in Argentina's military and said the country was ill-equipped to defend its seas.
"That a boat sinks in port due to a lack of maintenance reveals the deterioration and abandonment of our fleet, vital to the defense of a sovereignty that our president never loses an opportunity to proclaim to the world, but which we are very far from being able to defend," Congressman Gustavo Ferrari said.
He presented a study last year concluding that Argentina's army, air force, coast guard, and navy were all badly underfunded.
Meanwhile, Argentina's 3,100mile coastline is being protected by a fleet that has been reduced to three destroyers, two other warships, several patrol boats, two scientific vessels, an icebreaker, and the Libertad, the tall ship used to train cadets that was detained for months in Africa last year as collateral for unpaid debts.
Congressman Julio Martinez said Wednesday that of a total of 70 navy ships, only 16 are in sailing condition and, even then, only barely. He said increases in defense spending have gone to salaries, leaving little or nothing for maintenance or investment in hardware.
"It's hugely hypocritical to talk of sabotage when for 10 years the ship has been abandoned," Martinez told a TV station.
The Trinidad was mothballed only a few years after leading the ultimately unsuccessful occupation of the Falklands, which Argentines claim as the Islas Malvinas. Martinez said he, like most Argentines, has no desire to wage another war, "but if the country lacks defenses, and the British know that, they won't ever negotiate a peaceful resolution."
