The Dolphin Code

In between Engineer tours, I was the Submarine Liaision Officer for Carrier Group SEVEN, which was then the Battle Group staff for the John C. Stennis Battle Group. As such, I rode the Stennis for the Battle Group's 2000 deployment. We had two submarines (USS Asheville and USS Jefferson City) along with us, and my job, in addition to handling their waterspace management, was to do most of the communicating with the boats.
Since the first ASW exercises were run, submarine officers have been onboard the surface ships involved in order to provide a level of expertise on the various special rules that exist when working with submarines. Sometimes the submarine might want to pass a message to the submariner on the surface ship that he doesn't want the skimmers to see. To solve this problem, the Royal Navy and/or Canadian Navy invented the Dolphin Code. (The code I'm used to only had 80 options, so it's apparently grown in the last five years.)
The code is clearly British/Commonwealth in origin, but Americans still use it. I passed probably 5 messages back and forth with "my" boats using this code during my deployment; didn't really have to, since I could just send E-mails to the subs, but it was still kind of fun. Here are some of the more interesting code phrases:

4. My battery is:
A. 100%, I will simulate a Nuclear Submarine if you wish.
B. 75%, I will simulate a Nuclear Submarine for a short time if you wish.
C. 50%, I will not simulate a Nuclear Submarine, regardless of your wish.
D. 25%, I wish to simulate a Conventional Submarine, and will hot-pipe if you wish.
E. DEAD, I hot-pipe now, regardless of your wish.

13. I must temporarily withdraw from the exercise because of difficulties with:
A. Technical systems which are to difficult to explain.
B. Battery/motors/generators, I no go right.
C. Sonar, I no hear right.
D. Ingress of water, I no float right.
E. Fire/smoke, I no breathe right.
F. Personnel, I no lead right.

14. Please accept my apologies for failing to make the assigned rendezvous. My reason is as follows:
A. The navigator is a Newfoundlander.
B. I was doing something else at the time and didn't think you'd miss me.
C. I erroneously assumed that you would be where you said you would be.
D. My navigational equipment has not been updated since the Boer War.

25.
A. Your helicopter frightened me.
B. Your helicopter didn t frighten me.
C. I frightened your helicopter.
D. I wasn't aware you had a helicopter airborne.

26.

C. No, thank you, I do not require assistance.
D. Please do not render assistance, I need your help likea hole in the head.
