Mobile Suit Gundam: Thunderbolt Vol. 6
From the frozen wastes of Antarctica to the abyssal depths of the ocean, Operation Thunderbolt is under way. Io Fleming heads back into battle aboard the Federation MS carrier Spartan. While taking a perilous course through the Antarctic Ocean, Spartan is pursued by a Zeon submarine unit. Io takes the controls of the awesome new RX-78AL Atlas Gundam, but as always, it's not the machine but the pilot that makes the difference in the unforgiving crucible of combat.
