For the Navy, the crew of the ARA San Juan was killed by an explosion

What at first sight constituted an ordinary session of the bicameral Commission of Inquiry into the sinking of the submarine ARA San Juan, aroused unusual parliamentary and media interest because of the harshness and clarity with which the Director General Argentine Navy Equipment, David Burden, explained what conclusions were reached jointly with the representatives of the German company Thyssen, manufacturer of the ill-fated naval unit.

"It is clear that if we badume that water enters the battery tank and that its 24 square meters of free surface are flooded with hydrogen and that an explosion occurs, that equates to 10 tons of TNT, "he said.

And badyzed: "If we also consider that all this energy is contained by the resistant structure of the hull, the effects multiply, which indicates that the explosion was enough to end the life of the 44 crew members and from there, the uncontrolled submarine was thrown to the bottom of the sea"

According to him, the ship collapsed under the effect of the hydrostatic pressure at 700 meters depth, a phenomenon that was detected by the sensors monitoring the underwater explosions.

Although for the naval community and the experts who are investigating what happened, Burden's statements are not new, his simple and naked way of telling the results of the investigations carried out a few days after the disappearance of the ship surprised not only to the legislators, but to many of the families of the 44 deceased sailors.

In fact, more than one member of the commission questioned the reporter about the possibility that it was possible that a few days after the tragedy, with no official details about the incident, the Navy's leadership National has had so much detail about the incident.

"We are still talking in a hypothetical field, but we are responsible for investigating the possible causes of the accident and since the last communication from Commander Fernandez, the fire, the water intake and the hydrogen explosion were the variables. the most managed.", Assured the officer who belongs to the executive scale of the navy.

Doubts about the hydrogen measurement system

Simultaneously, both inside and outside the bicameral, the submarine's gaseous hydrogen monitoring system is giving rise to more and more doubts.

A group of naval experts is trying to clarify whether the forms presented before the drama by Fernandez himself and showing dangerous gas concentration values ​​in proportions of 4% or more are correctly expressed or if, on the contrary, they meet the new hydrogen measurement system that the San Juan had and that, instead of measuring the percentage of gas in the atmosphere, measure the probability of explosion. "In one case we would be in the presence of a time bomb, in the other we would have a very good risk condition," said one of the navy experts who studied the case to Infobae.

Although it is expected that the bicameral will be published in mid-June around the possible responsibilities in the tragedy, the legislators agreed at yesterday's meeting to ask the presidencies of the two chambers an extension of 30 days to finish with testimonials and testimonials. Prepare the report.

However, officials have already begun to outline the final report, which greatly reduces the allocation of responsibilities to policy makers in the field of defense.

"The defense chain of command is full of military officers with professional responsibility, who must alert the political power of any anomalies." You can not blame a minister for an operational accident, any more than the person in charge. when repairing the half-life by military or naval engineering decisions, "they explained to friends close to the commission.

Meanwhile, seem to have overcome the friction between the commission and the federal court of Caleta Olivia. "The commission is not there to search for the culprit, this task is exclusively that of the magistrate who takes the cause satisfactorily", they say at the National Congress.

A new theory of war. Although there is a general consensus on the causes of the sinking, marine engineer Jorge Bojanic denounced to the federal prosecutor Jorge Di Lello that the submarine had been the target of an attack while carrying out intelligence tasks.
