Command of an attack sub was the end of sea duty.

The attack sub was at a depth of one hundred feet, creeping north toward the edge of the ice.

The museum has a collection of miniature attack subs, scale models and other exhibits.

The carrier and three surface vessels, plus an attack sub.

Additional orders and updates of the tactical situation could be passed on to the attack sub then.

In five years every attack sub in the fleet would have one.

The rest of the escorts and the three attack subs are still heading home.

The other two were attack subs trying to work their way toward our task force at Bear Station.

We also have other attack subs converging on that area, but, well, it's a big ocean.
