The Bonaparte is a new heavy land battleship developed by the Atlantic Federation as a counter to ZAFT's Lesseps-class, as well as to serve as a mother ship to its devastatingly powerful mobile armor GFAS-X1 Destroy . It is fielded in CE 75.
The Bonaparte, like the Eurasian Federation's Compton, is a large, heavily-armed and armored land battleship, using heavy tank treads to travel across different types of terrain. Somewhat larger than the Compton, it is more lightly armed, with four dual beam cannons and ten dual machineguns, but lacking its counterpart's massive array of missile launchers. Besides these weapons the ship also features 32 smoke dispensers mounted accross its hull, allowing it to hide itself in a cloud of smoke if needed.
On the other hand, the Bonaparte has a higher mobile weapon capacity, being able to carry and deploy up to thirty-six mobile suits from its four lateral hangars. In addition to this, the ship is broad enough that mobile suits can stand on its decks and attack enemy units from there.
The large dome on the Bonaparte's back is tied to its primary purpose: The transportation and deployment of the gigantic heavy-bombardment mobile armor Destroy. The dome opens up to reveal a wide launching bay from which the Destroy is able to take off before moving into position ahead of the ship, while its conventional mobile suit forces provide additional defense against enemy attacks.
During the First Junius War, ZAFT’s Lesseps-class land battleships allowed them to establish supremacy over enormous swaths of territory throughout Earth, and once the war ended the Earth Alliance began taking steps to counter this advantage.
The Eurasian Federation was the first to field its own land battleship, the Compton-class. The Atlantic Federation soon followed up with their own plans for a land battleship, which resulted in the creation of the Hannibal-class; taller and broader than the Compton, it was more lightly armed but carried a higher number of mobile suits, with enough room for up to 36 conventional MS. In addition to these, the Hannibal-class was designed to function as a mobile support base for the gigantic mobile fortress GFAS-X1 Destroy.
Only one Hannibal-class ship, the Bonaparte, was complete in CE 75, and it was deployed by the Atlantic Federation in Eurasia, assigned to the command of Lukas O'Donnell of the 81st Independent Battalion. The ship was eventually destroyed by ZAFT's new battleship Minerva. The Hannibal-class was subsequently discontinued following the end of the war, and no further ships of the class were constructed.
