There was no immediate blast of power or skyrocketing acceleration by the Starfish but rather just a slight jerk as it backed tail first on the deck. The submersible slid up and away from the grasp of the propeller as the blade slipped down the compressor handle and clanged back to the hangar deck just inches in front of the Starfish's skids.
“Nicely done, sis. What do you say we go get some fresh air?” Dirk said, adjusting the thrusters to raise the Starfish up and out of I-411's hangar.
“I'm with you,” Summer replied with obvious relief.
Almost the second they cleared the walls of the hangar deck, the deep voice of Ryan blew loudly through communication earphones.
“Starfish, this is Sea Rover. Do you read, over,” came a monotonous tone that had obviously been repeating the phrase a thousand times over in the last few hours.
“This is Starfish” Summer responded. “We read you loud and clear. Have initiated ascent, please stand by for recovery.”
“Roger, Starfish” Ryan replied in a suddenly excited pitch. “You have some folks worried up here. Do you need assistance?”
“Negative. We just stubbed our toe down here. All is well; we'll be topside shortly.”
“Copy that. Standing by for recovery.”
Their ascent time, aided by controlled positive buoyancy, was slightly quicker than their descent, and in ten minutes they could make out the glowing bright lights of the Sea Rover's moon pool. The faint outline of the ship appeared as the submersible drew closer and Dirk tweaked the Starfish's thrusters with what little remaining power he had to guide them to the center of the glowing ring of beacons. Dirk and Summer both let out a silent sigh of relief as they popped through the hole in the ship's bottom and bobbed to the surface of the pool. Morgan, Ryan, and a half-dozen crew members ringed the moon pool and watched intently as the Starfish was plucked from the water by a hoist and lowered gently to the deck. Dirk powered down the submersible as Summer opened the rear hatch and the two climbed out for a grateful breath of fresh air.
“We were afraid you got lost down there,” Morgan smiled, then looked quizzically at the compressor handle that was still lodged in the grip of the left mechanical arm.
“That's our walking stick,” Summer explained. “We took a walk where we ought not to have gone and had a little trouble getting back out.”
“Well,” Morgan asked, unable to refrain from the other concern on his mind, “what did you find?”
“Two cartons of eggs waiting to be delivered,” Dirk said with a grin.
The Sea Rover's crew worked feverishly to repair the Starfish's mechanical arm and replenish the submersible's drained batteries while Dirk, Summer, and Morgan formulated a salvage strategy. Reviewing the video footage recorded by Snoopy, they calculated the exact position in the sub's hangar where the bomb crates were situated. Studying the video closely, they determined that the hangar's bulkhead walls were constructed in ten-foot sections.
“We should be able to cut through the original seams and lift out a ten-foot piece of bulkhead alongside the pontoons,” Dirk said, tapping a frozen video image with a pencil. “The Starfish is eight feet wide, so that should give us enough room to maneuver close and remove the bombs with the mechanical arms.”
“We're fortunate in that the currents around the wreck are only about 1 to 2 knots, so we'll be able to work unimpeded by the seas. It will still take us a couple of dives, though,” Summer added.
“Ryan can alternate dives with you two,” Morgan said. “Why don't you grab a few hours' rest while we turn the submersible around and prepare for some cutting?”
“You don't have to ask me twice,” Summer yawned in reply. Her sleep was short-lived, however, when Dirk woke her three hours later and they prepared for another dive. With a fresh set of batteries the Starfish was released again and they made their slow descent to the submarine. The submersible hovered off the side of the hangar facing the blast hole, then slowly moved sideways toward the conning tower. At six-foot intervals, measured by the width between the two semi-extended mechanical arms, Dirk would push the submersible forward and scratch a measuring mark on the encrusted surface with the left claw. At the tenth interval, or sixty feet from the torpedo gash, he scratched a rough A on the side of the hangar.
“This is where we cut,” he said to Summer. “Let's see if we can find the seams.”
Dragging one of the claws along the surface of the hangar, Dirk thrust the submersible sideways, leaving a long scratch along the wall. Moving back and closely examining the scarred section, which bled a dirty rust and gold, they quickly found an exposed vertical crease, representing the seam where two plates of the watertight hangar were welded together. As expected, another vertical seam was found ten feet away. While the Starfish hovered, Summer scraped away at the seams, using the claw like a knife, exposing the weld lines. When she was finished, a square outline in the shape of a garage door had been etched on the hangar.
“So much for the easy part,” Dirk said. “You ready to cut?” “Pop these on and let's get started,” Summer replied, handing him a pair of welder's protective glasses while donning a pair herself. Taking control of both mechanical arms, she reached into a basket mounted on the front skid pad and with the right claw retrieved an electrode holder, connected via a reinforced line to a 230-amp DC power source inside the submersible. With the left claw, she attached an iron oxide non exothermic cutting rod into the electrode holder and flicked on the power. Unlike a typical underwater cutting rod, which required a supply of oxygen to fuel the burn, the iron oxide rods simply required a power source to generate a superheated cutting arc. The less complicated design was more practical for welding at remote underwater depths. The electrical surge popped through to the end of the rod, igniting a brilliant arc of yellow light that flared from the tip, burning at several thousand degrees.
“Let's start at the top right corner and work down,” Summer directed. Dirk maneuvered the submersible to the corner seam and held it stationary while Summer extended the right mechanical arm toward the hangar wall until the high-temperature flame flared against the surface. With the Starfish suspended against a light current, Summer applied the heat from the arc to cut through the sixty-year-old plating weld. Progress was measured in inches, as the swaying of the submersible undermined the cutting efficiency. But, gradually, a surgical line appeared on the hangar wall, which lengthened as Dirk slid the Starfish down the seam. After fifteen minutes, the electrode rod burned down to the stub. Summer shut off the electrical power and replaced the electrode, then powered it up again and continued cutting. The tedious process continued until a fine cut was made around the entire perimeter seam of the hangar wall. With just a few inches to go, Summer worked the free mechanical claw into an open gap and grabbed onto the panel. She then cut the last of the seam, then yanked with the secured claw. The cut section broke free and fell back onto the main deck of the submarine with a swirling cloud of sediment.
Dirk backed the Starfish away and waited for the water to clear before moving up to their newly created entryway. As he maneuvered back in, he could see that they had measured perfectly. The pair of aircraft pontoons sat directly in front of the opening, the wooden crates sitting just below. He crept the submersible in as close as he could get, bumping the hangar ceiling a time or two before setting it down on the deck near a large protruding iron loop. Through the circular eyelet ran several cables, which secured the nearest pontoon to the deck while the submarine was in motion.
