before or during the jump to Mtensc, at 0901, PO Nobina Nkrumah of the engineering department announced itself to the door of the Small Craft Operations office, Main Hangar, portside, where the lieutenant Ishakhi K. Kimpasherki, commander of the Small Craft Operations, was filling out performance reports.
N'Krumah was an aged, non-imposing, black man, with a gray beard, evoking the image of a wise marabout from ancient Terran Africa.
Kimpasherki realized he'd seen the Petty Officer before, quietly working his shift in the sensor data and intelligence processing chamber behind the main bridge. Kimparsheki thought that, if the crew hadn't been brought together so recently, he'd certainly knew N'Krumah better.
Nkruma accepted whatever was offered to him, sat down, and - as expected - was soft-spoken. Ishakhi associated this melodic, gravelly voice to some audio reports, of which he appreciated the courtesy, brevity and relevance.
"the captain-baron wants us to submit proposals to improve the ship's efficiency in tracking pirates and smugglers", exposed Nkrumah. "The Chief Engineer - we met aboard the INS Zatsernem when she was ACE - designated me to lead a team working on finding original solutions to old issues like this."
"The ship is straight out of the naval base, so it's already equipped with the lastest sensor equipment technology. Though the ship has it's 'bad days', most of the time it's working efficiently and as expected. It's my 4th term as sensor tech, 2nd term as senior sensor analyst, and all that's left for me to do is operate tiny adjustments to the sensor settings. Since we're nearing the peak of the technical possibilities, we need to attempt new approaches to improve our operations. Let's sort the detection ops between the different configurations ; say 1.the search of asteroid belts and 2. the search in the vicinity of a gas giant."
"Say I'm the captain of a pirate ship in the Sestos system. I hide my ship near Sestos VIII, a Gas Giant popular for stingy merchant vessels who want to scoop the fuel for free. When my prey glide into the Giant's atmosphere, their sensors display become blurred ; my ship rockets to them, undetected, and attacks them while they exit the atmosphere. That's the rough plan."
"Now, instead of civilian ship, it's the INS Shasharna who's jumping at 100D of my giant ambush. It doesn't go undetected, so I detect it. For some reason, I don't want to rush on the opposite direction until I reach 100D and can jump out of the system securely."
"I see the vector the cruiser is taking, so I can predict its trajectory. Let's say my pirate ship - the Emperor Eduardo's Revenge - is hidden behind one of the 79 natural satellites of Sestos VIII which are longer than 1.5 km and provide enough concealment. I compute my orbit around this flying stone so as to always be in opposition to the cruiser, and the satellite shields me from detection"
"bear with me. The Shasharna's tactic is to go straight to the gas giant, wave after wave of active sensors blazing, and send your boats - Lieutenant - near the ships it detected, to check if their transponder ID corresponds, or any other reason. Then the cruiser goes round to the other side of the gas giant to complete the sensor scan of the other hemisphere of space, so to say."
"Meanwhile, the two other ships of my pirate flotilla - didn't I tell you it was a whole pirate fleet? This is Nkrumah Graybeard we're talking about!", smiled the sensor tech with his eyes gleaming. "There's one pirate ship near every of the three gas giants, to cover all the refueling sites. The two ships on the gas giants not approached by the Imperial cruiser have plenty of time to jump out, or reach and hide into an asteroid cluster, be it a belt, Trojan or Greek or at another Lagrange point."
"Now back to our naval role. We could circumvent the predictability of the cruiser's
trajectory by implementing an unpredictable, random-looking path, through the Giant's system. This trajectory however minimizes the distances between a lot of satellites, which the cruiser can proximity scan... The paternity - or more accurately the maternity - of the idea belongs to Itaa; she even wanted to plan a route for the shakedown cruise that would
not go simply from a world to the nearest, one parsec beyond... This has to be arranged with the pilot crew."
"What could you do with your boats, lieutenant, if we imagine that your boats' sensors were enhanced? Could you send them to the other GGs? How far can they go? Could you position your crafts so you scan the other side of the moons simultaneously as the cruiser scans the side it faces?"
