Su-27 SMN² Platypus II

Platypus II is the progenitor of the graviton floater technology, combining an N² reactor and a diamond-slit array. It is a joint manufacture between NERV Japan and the Japanese Strategic Self Defense Force, using the Sukhoi Su-27 as a testbed. This technology was later used in the UX-1 Allegorica system, utilizing the data accumulated from the development of Platypus II. It is equipped with a railgun that uses power from the N² reactor, and its speed can reach Mach 2. The original intent was to be used as air support for Evangelions, but due to the lease of Hakune from the United Nations, the cooperation fell through. Now the aircraft is used as transportation, mainly for Tōji Suzuhara's frequent travels. There are also extra-sided cameras that allow the user to see in various directions on the screen.

It uses an extremely powerful synthetic aperture radar to penetrate clouds and other gases that would normally block radio waves in order to plot a route to the Akashima. It also possesses a positron cannon with a specific camera for it.
