The CB-001.5 1.5 Gundam (aka 1.5 Gundam, 1.5 pronounced as Eyes) is an upgraded version of the CB-001 1 Gundam. It appears in Mobile Suit Gundam 00V: Battlefield Record, Mobile Suit Gundam 00P, and Mobile Suit Gundam 00I.

The 1.5 Gundam was specifically created as a general purpose machine for Innovade pilot, and its performance in various areas are 1.5 times that of its predecessor, the 1 Gundam. The main difference between 1 Gundam and 1.5 Gundam is the presence of back-mounted binders on the latter. These binders are capable of manipulating GN Particles in various ways to improve the suit's performance, and are armed with a pair of Binder Rifles. The binders can also function as a beam cannon, similar to GNMS-XCVII Alvaaron's wings. The suit's other armaments include a GN Buster Rifle, GN Shield, and 2 GN Beam Sabers,
