We could use a fathometer in the Pacific, for it had at least as many peaks as the Atlantic, but there was one difference. Most of these were coral formations instead of volcanic in origin. They should, therefore, be less precipitous, more gradual in slope in both directions, inherently less dangerous. As we moved along our course, we gained assurance in the various methods we had devised to get substitute depth readings, now that the fathometer was no longer working. Every day we became more certain of our ability to detect shoaling water under any circumstances. More and more, I knew that my decision to press on had been the right one.
As for our equipment, however, the trans-Pacific leg of our voyage began in a manner by then uncomfortably all too familiar. On the seventeenth of March, in the early morning, George Troffer, Triton’s Electrical Officer, stood solemnly outside my door. One of the air compressors which supplied the air pressure needed for certain automatic control systems had gone out of commission. As George explained it, the electric motor had apparently been slowly failing in its resistance to ground and, overworked as it was, had finally given up the ghost. Inspection of the motor had disclosed that the armature windings were entirely burned out.
This was disquieting news. Although we had stand-by controls for all essential systems, this would necessitate increasing the watch squad in certain areas. It might also, at the same time, result in some sluggishness in the automatic controls. I listened gravely as the technical tale of woe was unfolded.
“What about a jury rig, George?” I asked.
George nodded. “I was going to suggest one, Captain,” he said, “but I don’t know how you’ll like it …”
“Shoot,” I said, motioning him to the tiny built-in stool under my folding wash basin.
Troffer carefully perched on the stool, which had now been dubbed, so I had discovered, “the one-cheek hot seat.”
“We can get air from the ship’s main air system, though not at the right pressure,” Troffer explained. “But we do have some pressure-reducing valves among our spares, and I think we can rig them up. We’ll have to use two reducers in tandem and the pressure won’t be quite the same, but I think it’ll work.”
“Sounds good,” I said. “Where will you get the air from?”
“Well, maybe we can take it from the ship’s hundred pound service air main,” he said. “That would be the simplest, provided we can get the right reducing valve arrangement. Otherwise, we might have to take it from the four hundred pound air-pressure header.”
“You’ll need a pretty good length of hose or copper tubing to run it over to the control air system,” I said. “Do we have enough?”
“We may have to rob something else, but I think it’ll be OK,” George said. “If we have to take it straight off the four hundred pound header, it will be a pretty long run, though.”
“Well,” I said, “it looks as if we don’t have much choice. See what you can do.”
Troffer nodded. “I figured the same thing, Captain,” he said. “We’ve already started—one of the troubles, however, is that if we have to use the four hundred pound air system, we’ll have to run it through a watertight door. This will reduce our watertight integrity, because we won’t be able to shut the door if we should have to.”
“Not so fast,” I interrupted. “If you have to run a line through a door, let me know before you do, and at all times while that line is through the door, there’ll be a damage-control ax and a heavy set of wire cutters standing by. That’s easy.”
George’s face cleared as he stood up. “Aye aye, sir. That’s just what we’ll do.”
As Troffer disappeared down the passageway back toward the engine room, I could not help but reflect upon the tremendous competence Triton had working for her. One way or another, her control system would be working again soon; and I also knew that in due course the reason for the failure of the air-compressor motor would be discovered; its cause eliminated. Shaking out such bugs is always one of the objectives of a shakedown cruise, and Triton was at the moment indubitably on hers. The only difference was that an ordinary ship on a shakedown cruise is unperturbed by minor casualties, even if they temporarily reduce her operability. No one expects a brand-new ship to function perfectly the first time. We, however, had a mission to complete. Not only was the Navy depending on us, but there was also a tradition that no nuclear submarine had yet failed on a mission to which she had been assigned. No doubt it was this confidence in the dependability of Admiral Rickover’s ships which had inspired this voyage in the first place. We would not be the first to break the tradition.
I knew that this spirit and outlook had permeated our crew. But even so, I was surprised, a few hours later as I was wandering through the engineering spaces, to discover a group of toiling men, conspicuous among them Chief Electrician’s Mate Herbert F. Hardman—the same who had happily announced achievement of a thirteen-year’s ambition at the crossing-of-the-line ceremony—struggling to remove the ponderous inoperative electric motor from the control air compressor to a workbench some distance away.
“I thought I understood that we had no spare armatures for this thing, Hardman,” I said.
“We don’t, sir, but this damned motor shouldn’t have broken down. First, we’re going to find out why, and then we’re going to rewind it.”
“Rewind the armature!” I expostulated. “I’ve heard of Navy Yards and tenders doing that with all the extra equipment they have, but I know darned well we don’t carry any of that kind of gear!”
Hardman, as I had reason to know, was a man of great positiveness, as well as being an efficient Electrician’s Mate. His whole bearing spoke determination as he answered, “This damned motor is my piece of gear, and it’s going to be running before we get back.” His jaw muscles bulged slightly as he snapped out the last few words.
I remember wishing at the moment that I had had some appropriate rejoinder worthy of the occasion. All I could think of to say was, “Good!”
But if I was surprised in the engine room, what I saw that same day in the electronics technician’s storeroom was astonishing. Electronics Technicians G. E. Simpson, M. F. Docker, and N. L. Blaede had started constructing a new fathometer! A stainless-steel cooking pot had been commandeered from the galley, and a number of stainless-steel rods, plus considerable small, fine copper wire from the engineering and electrical spare parts petty officers. The technicians had calculated the resistances and impedances and were busily engaged in constructing a new sound head.
“Certainly it’ll work,” said Docker. “The question is whether it will be powerful enough to do the job for us, and whether we can find some way to put its signal into the water.”
Another project they were working on was the conversion of one of our general announcing speakers into a sonar transmitter, a conversion that involved developing a means of making it both watertight and pressure-proof at the same time, and yet able to transmit and receive sonar signals. A third, and much more primitive idea, beating on the bottom of the hull with a hammer, was ready for trial as soon as we happened into shallow water again. All these projects were based on the hope that we might be able to catch an echo on one of our other sonar sets and, by timing it, ascertain the depth of water.
I could only marvel at the ingenuity of the American sailor. These experiments might not work, but all three were certainly worth trying.
The last-named idea required no special preparation other than finding the best spot for hammering on the hull, a suitably heavy hammer, and a brawny sailor. Years ago, when the submarine S4 lay sunk on the bottom of Cape Cod Bay, communication had been maintained with the survivors by means of hammering against the hull. It was just possible that enough energy could thus be placed in the water for our modern and acutely sensitive sonar to pick up a returning echo from a nearby shoal.
