Torpedo cannon
From MediaWiki

Nautilator's potent triple crusher cannon can crush even the toughest of alloys into a compact ball, and almost makes up for his clutzy performance. But for whatever reason, Piranacon isn't happy with mangling his victims into a ball, so he has Nautilator's Triple Crusher Cannon somehow turn into a heat-seeking torpedo cannon in Targetmaster mode. Nautilator probably blames Piranacon for not pulling the trigger correctly, or leaving the non-existent safety on when he jams.

Notes
- Nautilator's AtoZ profile in the Marvel UK 1989 Transformers annual completely omits any mention of his third mode for some reason, instead the torpedo cannon is described as just another weapon at his disposal.
