It was pitiful how shabby and makeshift it looked. The old engines had been ripped off the stern and replaced with a jury-rigged attack tunnel, a long, flexible, accordioned tube with the jagged teeth of a converted mining drill at its end. A new engine, one of the old-fashioned Shaper electromagnetic SEPS types, had been welded on at the end of four long stanchions. The globular engine was a microwave hazard and was kept as far as possible from the crew’s quarters. Foil-wrapped control cables snaked up the stanchions, which had been clumsily bolted to the stern deck.
