Had circular escape hatch on top of the turret which was extended to keep it above the waves. There was a tower above the rear deck to keep the exhaust clear of water.
It had smooth sides with pontoons attached to the front and rear, which were detached once it reached shore.
Encountered at Kwajalein.
