M90A Gauss cannon

The M90A Gauss cannon is a 30mm Gauss cannon employed as a primary weapon on the S-930 Pegasus strike fighter.

Production notes
The M90A's designation and place on the Pegasus fighter is a reference to Isaac Hannaford's original concept art for the FSS-1000 Sabre fighter produced for Halo: Reach. In Hannaford's original art, he lists two 30mm rail cannons, with one on either side of the fighter.
