A Northampton-class heavy cruiser of the US Navy during World War II. Along with Chicago (CA29) and Houston (CA30), Augusta (CA30) were designed to serve as flagships and thus have extended forecastle deck.
(Bar locations of 20mm light AAs and some platforms, can also be used to represent USS Chicago (CA29) of the same year; USS Houston never received the same modifications at the time of loss)
