"그들은 고통을 겪거나 익사하지 않았다. 그들의 죽음은 순간적인 것이었다,"라고 이 보고서는 말하고 있다.

아르헨티나 해군은 아직 언급하지 않았다. 미국 해군 본부가 아르수이아 산 후안 호가 10노트에서 13노트 사이의 속도로

파열하여 침몰했다는 사실을 밝혀 44명의 선원 모두를 즉사시켰다.

2017년 11월 15일 ARASanJuan내부 압력이 388미터 깊이에서 발생한  (수압->운동에너지)발생한  폭팔은 

음향 신호로 TNT폭발 환산 5,669kg  달했다고 한다. 

이 잠수함은 11월 15일 레이더에서 사라졌고 미 해군 정보국에 따르면,

같은 날 이 선박에서 나온 것으로 감지된 음향 신호가 있었다.

Analysis of Acoustic Detection of the loss of the Argentine Submarine San Juan

Ananalytical review of all information released by the Comprehensive Nuclear-Test-BanTreatyOrganizationon the acoustic signal associated with the loss of the Argentina Submarine ARA SANJUAN confirms the following:

• That acoustic signal originated near 46-10S, 59-42W at 1358Z (GMT) on 15 November 2017. "It was produced by the collapse (implosion) of the ARA SAN JUAN pressure-huli at a depth of 1275-feet". Sea pressure at the collapse depth was 570 PSI".

• The frequency of thecollapse event signal (bubble-pulse) was about *4.4 HZ".

• The energy released by the collapse was equal to the "explosion of 12,500 pounds of TNT" at the depth of 1275-feet".

• That energy was produced by the nearly instantaneous conversion of potential energy (sea-pressure) to kinetic energy, the motion of the intruding water-ram which entered the SANJUAN pressure-hull at a speed of "about 1800 mph".

• The "entire pressure-hull was completely destroyed" (fragmented/ compacted) "in about 40 milliseconds' (0.040s or 1/25th of a second), the "duration of the compression phase of thecollapse event" which is half the minimum time required for cognitive recognition of an event.

• Although the "crew may have known collapse was imminent, they never knew it was occurring".

• "They did not drown or experience pain. Death was instantaneous".

• The "SANJUAN' Wreckage "sank vertically" at an "estimated speed between 10 and 13 knots". Bottom impact would not have produced an acoustic event detectable at long range".
