Acid Air

CHAPTER 1Greg was annoyed with himself. After all it wasn't that he was an amateur, not after ten years in the Royal Australian Navy, five years on submarines and an advanced degree in deep sea diving. He had become careless and this was the price; six hours in the decompression chamber after getting the bends. He sighed and rolled over so that he could see out the double glazed window. It was strange! The room outside was empty while the smooth vibration indicated that the submarine was submerged. This was typical for the Russians; casual as hell but still thinking they were involved in the cold war of a generation before. That would be why nobody was monitoring the chamber and also why the submarine was submerged so close to American waters around Hawaii. He checked the dials. Even though the signs were in Russian it was easy enough to read the numbers. He must have dropped asleep for a couple of hours and had reached the time to be able to leave. The gauge also showed that pressure inside and outside his chamber was the same. Good, he was hungry and could do with a shower. After there was no response to the buzzer that he sounded, he spun the wheel to unlock the hatch and pushed it open. The nuclear engine was far quieter than one in the conventional submarines he was used to but the steady hum of the air-conditioning seemed normal. However the lack of other sounds was unusual. He waited but still nobody arrived so he slung himself up and out of the chamber. At least he felt fine now with no after-effects. "Anyone there?" he called out in English and repeated his words in halting Russian that the thirty-four skeleton crew of the K264 understood. This nuclear submarine was one of the ballistic missile carriers of the Soviet Union but was now decommissioned and taking its final journey to be sunk in one of the Pacific Ocean deep troughs east of Hawaii. He never liked the idea of sinking a nuclear device there but at least the missiles had been removed and the engine was encased in double insulation that, in his opinion was as good as, if not better than that used by the Americans or British submarines. The hull could withstand pressures far deeper than the ocean floor so the chances of leaks were infinitesimal. International agreements on the disposal of nuclear rods were still being ignored but that didn't worry the Russians. His company had won the lucrative contract to sink two submarines in the depths and he was back to supervise the second sinking. The scuttling of K213 two months earlier had been moderately successful. It had been sunk in a deep trough north-east of Hawaii but it appeared that his data on the ocean depth was incorrect for they had lost contact with K213 after it dropped below the two thousand five hundred metre shelf it should have landed on. However, after rigorous tests on the surface and at a hundred metre depths, no trace of radioactivity had been found. It was safe to assume, therefore that the nuclear rods in the submarine had survived the extreme water pressure on the ocean floor. Even if the submarine itself had been crushed; as long as the nuclear fuel was intact the ocean remained unpolluted. Back in Vladivostok, the Russian authorities seemed to be more worried about the Americans tracing the sunken submarine that any natural catastrophe cause by a nuclear leakage. After Russian trawlers that were in reality spy ships, used more sophisticated equipment than his own to check the water around the site, it was declared that he had successfully scuttled K213 and the go ahead to sink the second submarine, this one in another branch of the trough about twenty kilometres north of the first sinking. Greg frowned as he dressed in casual clothes and noticed something else out of order; the air smelt wrong with a faint aroma like burnt toast. He shrugged as he wandered out into the companionway and up a ladder to the deck above where the smell was stronger. It was empty, as was the next deck and everywhere he searched. Now concerned, he moved onto the control room that was more like that of a large aircraft than a ship. There were usually at least five officers there including a pilot who sat behind a wheel with a myriad of instruments and monitors before him. Now, though, everything was operating but the deck was empty. No, not quite! Six cone shaped piles of white ash, each only a few centimetres high, sat on seats and another was on the floor. He walked up to the pilot's seat and touched the cone there. It felt warm and collapsed when he applied pressure. That whiff of that burnt toast hit his nose as the ash collapsed. Oh my God, could these be the incinerated remains of the crew? He swallowed his panic and just stood there for several moments gazing around and thinking. Obviously, something terrible had happened. He needed to check the life support systems. Again, the readings were in Russian but underneath many of the English translations had been written on yellow cardboard. He checked and found that everything appeared okay, oxygen content, air pressure, humidity and other life support data registered as normal. There was no build up of carbon dioxide and the temperature was the usual twenty degrees Celsius. Further checks showed that the nuclear reactor and two engines were working perfectly and the submarine was travelling at normal cruising speed. He tapped a keyboard to bring up a map that showed their original destination right down the bottom of the screen. They were travelling northeast away from it. He frowned and added a request to show the submarine's destination. A map appeared to show that they were on a circular course with a hundred-kilometre radius. It appeared that somebody had had time to submerge and set a course before they disappeared or more likely were vaporised or incinerated. He searched further and entered a small alcove where the navigator sat. Here the ash cone was sort of tipped sideways across a console. A computer lit up when he touched a keyboard and words appeared in the Russian script. He hit some keys to convert the alphabet and had a translation made. Acid Air. Submerge. Another sentence followed but it only translated as There was no time! Without… That was it! Whoever it was must have succeeded in making an emergency dive, set a new destination and switch on the autopilot before they themselves died. Without their bravery, he probably would not be alive now. "Thanks my friend," he said as he lifted the ash in his hands and placed it gently in a small paper mug on the console. He gulped and decided to do the same with the other piles of ash. He found a pile of paper mugs and spent almost an hour methodically placing each pile of ash in a mug, noted on the outside where it was found and afterwards placed them all in a storeroom container. If he survived, the ashes could be returned to Vladivostok, the crews' home port. Now slightly overwhelmed by the events, he counted them and whispered a brief goodbye for each one. There were thirty-two! He alone had survived whatever had happened on the surface. He needed to contact somebody and head for the closest port in Hawaii to the southwest. However, there must be navy or civilian ships closer. This part of the Pacific was a busy shipping lane between North America and Asia. To establish contact he would have to go within twenty metres of the surface to use Gertrude, a VLF underwater system. The Russian ZEVS system used to communicate with their operational submarines in the North Western Pacific was out of range. Anyway, along with all armaments, sophisticated communication equipment had been removed when the submarine was decommissioned. He thought about the situation and decided to try to listen for any incoming signals. Even if they were encrypted it could show that the system was in operation. For an hour he sat before the radio and tried every frequency available. However, nothing came from the speakers, the onboard computer showed nothing except previous recorded signals in a sixty-four symbol code. These had abruptly stopped two hours after he had entered the decompression chamber. He switched his tactics and fed in questions to the onboard computer. Luckily before their journey, software had been added to the Russian computer that converted it to show English as well as Russian alphabets and languages. In theory, the submarine could stay beneath the surface for months with recycled air and water. The only limiting feature was the food on board. With enough stored to feed the skeleton crew for a month, by himself he had enough for months, if necessary. He shuddered at the idea and requested information about the ocean. The report was hopeful. It appeared that the ocean conditions were normal with fish and other underwater creatures still there. However, when he fed in questions about the surface conditions he received nothing in reply. Also, his own tablet and satellite phone that he had brought aboard made no contact with The Silver Rose, the surface ship that was meant to be at the rendezvous point where the K264 was going to be sunk. "Okay Greg," he muttered to himself. "Let's take the sub up in periscope range and have a peep at the surface above." One thing he did like about the Russians was that they still had inbuilt manual systems that had long been discarded by the western nations. "I wouldn't advice that Commander Freymore, not after all my efforts to keep you alive. Poisonous air from the surface will contaminate the air supply and your survival would be forfeited," said a slightly accented female voice in English. Greg's jerked in alarm before his military training seized him. He swung around to see a young woman dressed in a modest yellow dress and grey cardigan standing across the control room. He swallowed as thoughts of defence rushed through his mind. Who was she? How did she get aboard for there were no women in the crew? On second thoughts, she appeared to have no weapons and being quite petite, could probably be physically overwhelmed easily, if it was necessary. "Who are you?" She smiled. "Part of the original top secret equipment the Russians had installed in this vessel the year before they ran out of money and decided to mothball most of their Pacific fleet. K264 was one of their most advanced submarines but was unproven and therefore decommissioned along with earlier submarines such as K213 that never had this upgrade." She shrugged. "Typical Russian attitude." "So you had some sort of chamber like myself and survived whatever the catastrophe was?" "No I was always here." Greg raised his eyebrows. "Not physically though, Greg, can I call you that?" "Why not? I'm a civilian now. And your name?" "The last Russian Navy crew called me Nedda Solnechniy, my surname that means little sun. I guess it helped them to remember their wives, partners and girlfriends back home. Three month journeys under the ocean can become monotonous." "Go on," Greg hissed. He was becoming annoyed at this woman almost taunting him. "What you see is a hologram. Come and test me, if you like." Greg nodded and with extreme caution, stepped forward to stop a couple of metres before her. She was shorter than himself, weighed fifty or so kilograms, had that slight Russian face with high cheekbones, tanned Caucasian skin and brunette hair. Her eyes looked alive and he could see nothing that indicated that she was anything but an attractive woman in her mid-twenties. That was until he reached for her outstretched hand. When he went to clasp it, his own hand went right through her one with the only sensation being a slight tingle like a slight electrical shock. In spite of himself, he jerked back in alarm. "I did tell you," Nedda whispered. Greg stared into her eyes. "Point taken. So you're a hologram produced by the inboard computer but why have you shown your capabilities now and not earlier?" She grinned, walked across to a swivel chair and sat down without actually moving the chair. Greg took the hint and sat in an adjacent chair. "I am not really the inboard computer but a subsidiary one that was removed along with all the military hardware when K264 was decommissioned. Your first submarine, K213 never had the operating system the computer I am associated with has to run this vessel." "But you're here!" "Yes. I mutated into the main computer. They removed my main drive but they couldn't take the main computer out as it is needed to keep the submarine operational for its final journey. By the time I was disconnected, my software had already upgraded the main computer." "Okay but why was there a delay before you made yourself known to me?" "Several reasons. One is that I needed to learn the English language and alphabet. This took a while as the original translation software stopped working when the emergency occurred. Being by yourself, you didn't need to speak a lot but your goodbyes to the crew ashes helped me refine my language capabilities." Greg ran a hand over his face. This was one sophisticated computer. "So my decision to go to periscope depth motivated you to contact me?" "Yes. I could merely override any manoeuvres you made to take the submarine to periscope depth and save your life. This could be frustrating and you could decide to manually blow ballast tanks and take K264 up, anyway. As you now know, you cannot touch me. The opposite is also true. I cannot physically touch anything for I am but an image. If you manually blew the ballast tanks I could only incapacitate you in one way." "How?" "I could give you an electric shock to knock you out but chose to reveal my presence to you instead." "So what did happen on the surface?" "I don't know how or why it happened but know that the air is toxic with oxygen levels far below that needed to sustain life and the atmosphere also contains potassium cyanide. That's the poisonous gas the Americans used in their gas chambers for execution of criminals a generation ago and the one that killed this vessel's crew." "But their bodies also disappeared." Nedda gave a slight smile. "That was my doing. I could not help anybody except you. When I realised you would survive, I needed to keep the keep the submarine healthy for you. Decomposing bodies and they were in that state when I reacted, needed removing. I used high-powered laser beams to incinerate them. Those small cones of ash were the aftermath." "After only a few hours?" "No. To keep you alive, I placed you in a coma for a week. I managed to operate robots to give you water and a small amount of food in liquid form." "Why was this necessary?" "The poisonous air aboard had to be pumped out and replaced. Even the onboard emergency oxygen supplies were contaminated." "Thank you," Greg replied. "But how did you get fresh air to replace it?" "Luckily, the atmosphere hasn't penetrated the ocean more than fifteen metres, round about the periscope depth you intended to go up to, actually. Below, that the ocean has not changed and my equipment can extract breathable air from seawater in much the same way that fish use their gills to breath." Greg frowned. "New technology?" "Yes. Our scientists designed it but the Americans probably have similar equipment in their submarines. The western military still keep their secrets and little top-secret information is shared with us even though we have been allies for a generation now." This was true. Even the Australian Navy had trouble getting modern hardware from the Americans and tended to rely on British or European companies for their most sophisticated military equipment. Nedda continued. "Only after I was sure the air was fresh that I let you awaken." She shrugged. "The rest you know." "So what happens now?" Nedda stared at him. "Why should I know?" "Okay, let me rephrase that. Do you have any suggestions about what we should do next?" "No." Greg grimaced and stared at the girl. Of course she was really just a computer. He would have to ask for something that she could answer. "I would like the surface above us searched for signs of human life." Immediately a monitor that had been unused lit up on the console and showed a rotating pulse-like beam. "There are no living creatures above the surface for a hundred kilometres in every direction." Nedda reported. "Do you wish to extend the search?" "What range can the search go?" "It is accurate for five hundred kilometres but beyond that, the atmospheric conditions make readings inaccurate." "Okay extend the search out five hundred kilometres. That should reach Hawaii." The monitor data zoomed out but the rotating beam never fluctuated. "There is no indication of any life," Nedda added. "Can you find bodies?" "No. The body heat of living creatures is measured. A cold body does not register." "Can you search for metal objects such as boats?" "There are none," Nedda replied. "None?" Greg gasped. "Not even empty hulks with nobody alive on them." "There are no surface ships within range within the five hundred kilometre range." "What else can you search for?" "We can continue a search for electronic signals. There are none at the moment but if any become available I can record them and note where they come from." "And you can still test the air above us?" "Yes. It is still poisonous. Any fluctuations will be recorded and I will notify you if it becomes suitable to support human life." "So we'll head east towards Hawaii. There must be some survivors there somewhere." "I would suggest travelling west. We could enter a different weather pattern. Perhaps the air five hundred kilometres away hasn't been contaminated." "You say perhaps?" Nedda frowned. "The chances of this are ten to one against." * By evening using Hawaiian Standard Time, Greg was worried about almost everything that had happened. Nedda had discretely disappeared and he sat eating an evening meal as thoughts churned over in his mind. For most of the afternoon she had searched the conditions outside K264. The only positive sign was of the ocean itself. Below twenty metres, it was normal with fish life abundant but the marine mammals had gone. He guessed that this was because dolphins or whales would have been asphyxiated when they surfaced. There were no other submarines around. Being close to the Hawaiian navel base this was unexpected. This concern was reflected in the continuous surface search. No ships or crashed aircraft showed. According to Nedda, the surface within the five hundred kilometre radius that they monitored was empty. Monitors on the console supported her reports. On the electronic front, again nothing was registered, undersea navigation transmitters were silent and satellite transmissions couldn't reach them. His own tablet and satellite phone registered nothing. Nedda could offer no opinion without more input of information but he had not mentioned a theory he had built up. What if the submarine was surrounded by a natural cloud or electronic forcefield that was so dense that no signals could pass through it? Everything beyond could be normal. And what of the girl herself? It helped to think of her as a person. If she was as sophisticated as she seemed, couldn't she be withholding information from him? Perhaps the submarines monitors were purposely changed to register nothing. Could he trust her? He shrugged and decided he needed to. The counter argument was that if she was some sort of enemy, why had she bothered to save his life in the first place? It would have been easy to just let the poisoned air kill him along with everyone else aboard. "Greg!" He glanced up and noted that Nedda was now wearing a white top and jeans. Why would a hologram bother to change in appearance? He shrugged for it wasn't important. More so was the expression on her face. She looked excited! "What is it, Nedda?" "I have picked up an incoming signal. Somebody is trying to contact us." *
