No. Still, she's one hell of a ship with a great crew, though, especially the one from Yamato 2199. That one has shields that easily shrug off nukes. The key here is having them team up, not fight each other. Together, they'd raise hell against the cylons. I think Adama would welcome Okita's help.
It's from the HALO games. It's over 5 kilometres in length and near 1 in height, possesses advanced energy shielding, a huge amount of powerful weaponry, a massive complement of military forces, and carries a battlegroup of ten Strident-Class Heavy frigates (each a little over 500 metres in length) within ventral launch bays. The frigates are carried vertically, so they literally drop downwards from the parent vessel. These Frigates also possess energy shielding.
And both the Infinity and the frigates are capable of atmospheric operation.
