Ckalk up another one with the DO method
I recieved a radar contact at 10nm, bearing 75 degrees. I turned towards the contact and reduced speed. I took a bearing and estimated range and made my first plot. Started the stopwatch for 3 min. took second bearing and estimated range. I determined that the target course was NW.
I plotted a course 90 degrees to the target track, and prepared the torpedoes and TDC. Monitoring the radar screen, the range began to close until the "ship spotted" alert rang out. Training the TBT at the announced bearing, I saw the outline of a ship in the darkness. He's getting close now.
I swung my bow around just ahead of him, and timed him as he crossed the 0 bearing line of my TBT. It took him 21 seconds. At this point I fear he may see me, so I go to PD. I up the Obs. Scope (useing the color filters mod; I use the yellow one. ) and ID him as a Medium Modern Comp. Freighter. I have a list that I hand wrote of all the ship lengths. Useing the simple formula to find speed, I determined him to be going 10k.
At this point everything is set: TDC, torpedo speed and depth, target speed and AOB. Nothing left to do but open the outer doors and wait for the ship to cross my scope. Two Mk 14's speed off and impact 30 seconds later
About a half hour after that, down he went. I'm truely beginning to love this targeting method
