I have diligently updated the sound contacts in the Broadband Sonar station, being as accurate as possible with the bearings. I am confident that the TMA solution for the cargo ship from the sonar bearing updates is accurate. However, not wanting to leave anything to chance, I go to the USNI Reference to attain the TPK (Turns Per Knot) for the cargo ship.
Using the DEMON (Demodulated Noise) Display station I confirm that the speed from the TMA solution matches that of the DEMON.
I am now 100% confident that I have a valid attack solution.
I decide now is the time to press home my attack. The freighter S05 sits between myself and the Perry FFG. I decide to use this to my advantage and set my speed to standard enabling me to substantially close the gap between the cargo ship and myself.
The background noise generated by the water rushing over the hull blind me.
After five minutes I slow down to 1/3 speed to take a fresh set of sound bearings.
I again set my speed to standard for five minutes. I confirm the sound contacts against the Navigation station.
In the Fire Control station, I assign the torpedo tubes to the target…
…and allow time for the TMA to be downloaded. Time to launch the torpedoes, I flood the tubes, equalize the pressure, open the muzzle…
…and lift the fire safety.
I sit there for a short while going over everything making sure that there wasn’t a mistake. No, everything is right. I am sure of it. With that, I press the fire button on torpedo 1, Sonar reports “torpedo is running normal”.
