The F90M Gundam F90 Marine Type (aka "M-Type") is an amphibious combat mobile suit, it is featured in the model kit and original design series Mobile Suit Gundam F90.

Technology & Combat Characteristics

One of many F90 Gundam F90's optional armament variations developed by the Strategic Naval Research Institute between UC 0110s and 0120s, The F90M Gundam Marine Type (or "M-Type" for short) is designed for underwater combat.

Because rocket thrusters are highly ineffective, in order to increase underwater mobility the Gundam F90's rocket thrusters are complimented by a pair of hydrojet thrusters that allows the F90 to move at speeds up to 90 knots. The hydrojet backpack also includes control surfaces to adjust the F90's profile to improve mobility. For combat the F90 only retains its head Vulcan armament while mounting various weapons designed for aquatic use including torpedoes, marine rockets, an arrow shooter, and a combat knife.

The Marine Type equipment also includes additional sensor and communications equipment designed for underwater operation. The Marine Type can plunge to a maximum depth of 400 m, 1.6 times more than that of the MSM-03 Gogg.


  • 60mm Vulcan Gun
The Gundam F90M is equipped with a pair of head-mounted twin-linked Vulcan Guns to serve as a mid-close range defensive weapon. While it can normally do little damage against the armor of a mobile suit it serves as a much more efficient and cost-effective means to shoot down incoming missiles or small lightly-armored targets such as ground combat vehicles or attack helicopters, as opposed to using the beam rifle, the power of which would be over kill and is far more limited in ammunition.
  • Homing Torpedo
Since water reduces the effectiveness of beam weapons, the F90M Gundam opted to return to the torpedo, a far less modern weapon. This self-propelled weapon with an explosive warhead is able to be launched toward enemies, then detonated on contact or within a proximity to the target. There are two torpedo for each leg-mounted launcher, making a total of four torpedoes which the F90M Gundam can carry.
  • 3-tube Marine Rocket Pack
Like the F90D Gundam F90 Destroid Type, the M-Type also has two rocket launchers built into the MS's forearms (though the rocket launcher on the M-Type can only carries 3 to the D-Type's 5.) These grenades are moderately powerful self-propelling explosives that can deal significant damage to a MS, but are particularly effective against machines with heavy defenses against beam weapons.
  • Combat Knife
Instead of a beam saber (which would works terribly underwater), the F90M Gundam carries a combat knife for melee combat. When not used, the knife is stored on left hip armor hardpoint.
  • Arrow Shooter
A hand-carried weapon, the arrow shooter acts like a modern speargun, propelling short spear-like projectile at high speed so as to pierce the enemy's armor. The arrow shooter can load 6 arrows maximum in its cylinder, not unlike a revolver does.

The M-Type was completed along with the A, D, S, H type options in September, U.C. 0111, although they only went into field testing in U.C 120. The F90 Gundam was stationed on the Ra Cailum-class Admiral Tianem as part of the 13th Experimental Battle Group. Its pilot was Def Stallion, an employer of the Strategic Naval Research Institute. The Admiral Tianem came into conflict with the Mars Zeon during a test flight near Side 4 on October 28. And although the E.F.F emerged victorious in this brief conflict, it costed them both of the F90 Gundam F90 units.

Another Gundam F90 unit was built between U.C 120 and U.C 122, and it participated in the war with the Mars Zeon, who, under the leadership of Charles Rochester and their ally the Crossbone Vanguard, had began in their invasion of Earth. The Gundam F90, and the F90M Gundam F90M in particular, was piloted by Bergh Scred.
