It's not. The left-most Argama is the Pegasus III like scythedd7 said, notable for it's lack of gravity blocks. The center ship is the Nahal Argama, identifiable by it's longer right catapult and color scheme, as well as it's 380 meter length. The thrid Argama, the right-most one, is the original Argama.Dark Duel wrote:IIRC, the Argama-class ship(or ships) featured in Gundam Sentinel had that paint job.
That said, I've no idea why the Argama from Zeta is on there twice.
Yet again in this thread, ZZ gets not love.
