The "Shinju" LSC is a tugboat with a push beam and a stop beam. Tugboats are most useful in positioning thrusterless rail components and moving turrets during station construction. They can play some mean asteroid football as well.
Equipped with a powerful jumpdrive and scanner, the Shinju also can be an effective scout/explorer.
The Shinju has a rail elevator to enter the interior and has no means to dock to rails when stock.
