This sub was sunk on order from the british Royal Navy and the French navy and the Italian navy.
So much for having the former president Kirchner to capitulate ...

If it is an electrical problem, it may be DIW on the surface. There are few things that could make it sink uncontrollably if it is purely loss of electrical power. Certainly, they would never try to submerge with any kind of problem.
Usually, there are emergency beacons and crank-up radio generators, if they had have such equipment. They are usually packaged in the life rafts.
I certainly hope that they are all ok. If they are on the bottom, it better be above crush depth, as conventional boats probably cannot maintain hull integrity lower than 900ft. God be with them.
Dive depth The dive depth cannot be increased easily. Simply making the hull thicker increases the weight and requires reduction of the weight of onboard equipment, ultimately resulting in a bathyscaphe. This is affordable for civilian research submersibles, but not military submarines, so their dive depth was always bounded by current technology. World War One submarines had their hulls built of carbon steel, and usually had test depths of no more than 100 metres (328 feet). During World War Two, high-strength alloyed steel was introduced, allowing for depths up to 200 metres (656 feet), post-war calculations have suggested crush depths exceeding 300m for late-war German Type VII U-boats. High-strength alloyed steel is still the main material for submarines today, with 250–350 metres (820 to 1,148 feet) depth limit, which cannot be exceeded on a military submarine without sacrificing other characteristics. To exceed that limit, a few submarines were built with titanium hulls. Titanium has a better strength to weight ratio and durability than most steels, and is non-magnetic. Titanium submarines were especially favoured by the Soviets, as they had developed specialized high-strength alloys, built an industry for producing titanium with affordable costs, and have several types of titanium submarines. Titanium alloys allow a major increase in depth, but other systems need to be redesigned as well, so test depth was limited to 1000 metres (3,281 feet) for the Soviet submarine Komsomolets, the deepest-diving military submarine. An Alfa-class submarine may have successfully operated at 1300 metres (4,265 feet), though continuous operation at such depths would be an excessive stress for many submarine systems. Despite its benefits, the high costs of titanium submarine construction led to its abandonment as the Cold War ended.
The Argentine Sea is located in the South Atlantic Ocean off the southeastern coast of Argentina, extending from the approximate latitude of Montevideo, Uruguay, southward to Tierra del Fuego, and is situated about 500 mi (800 km) north of Antarctica. The Argentine Sea has a surface area of 390,000 sq mi (1,000,000 km2) and is one of the largest seas in the world. The average depth of the sea is 3,952 ft (1,205 m) and the maximum depth is 7,296 ft (2,224 m).
Mr Balbi told journalists: "Today is the seventh day, which was critical for oxygen capacity."
The loud noise happened four or five hours after the submarine's last radio contact, about 30 nautical miles (60 kilometres) north of its last-known position. "It's a noise," Mr Balbi said. "We don't want to speculate."
