Arv’s seacopter and Mel’s jetmarine were to maintain close formation and stand guard while Tom’s craft did the actual searching.
Now the missile hunt began. Tom had plotted a concentric search pattern, focused on the probable position worked out by the task-force computers. After checking his fix on the automatic navigator, Tom switched on the Damonscope and steered the Sea Hound on a gradually circling course.
