Created at the same time as MSB-004-1ST, the Corsair is on the opposite side of the design spectrum. Pushing the envelope between Battlesuit and Light Mech, MSLAM-001-1 is far larger than a P-Type battlesuit.
The P-Type origins of the ST2 are evident in many of it's structures which makes maintenance less expensive. It takes very little time to upgrade the training of technicians used to working on a P-Type battlesuit. While exact records are vague it is assumed that work on the Corsair began when the Goliath design was rejected.
These battery packs give the suit access to large amounts of power for short spurts. These mounts can also be switched out for other equipment but would leave the suit without access to these power reserves.
The twin beam cannon draws off the suits primary powerplant feeding two rapid charge capacitors. This weapon builds up heat extremely quickly so the barrels fire in sequence each giving the other a small fraction of a moment to cool. In the vacuum of space this is sufficient, but in an atmosphere the weapon can rapidly overheat if used for extended periods of time.
While the Corsair is assigned to the R&D division of Midnight Sun, it has been repeatedly deployed into combat in defense of spaceborne troop transports. There are also some gaps in the service record that would indicate that undocumented missions were performed.
It is unknown whether either of the S-Type suits will ever see widespread production. Shortly after MSB-004-1ST and MSLAM-001-1 were completed focus began to shift to the P-Type project and modular add-ons that will allow them to operate in more environments. The company policy seems to be shifting to a more versatile single platform rather than specialized battlesuits.
Although on average not as fast as the MSB-004-1ST (In short bursts it is actually slightly faster) this suit can maneuver just as well and is capable of taking far more punishment. However, it's larger size makes it less suitable for boarding maneuvers.
The Corsair is also seen as a potential ship-killer. Able to maneuver inside a ships defenses and deal damage with pinpoint precision allowing ships to be disabled and salvaged rather than destroyed utterly.
Unlike the MSB-004-1ST, the Corsair does have a permanently assigned pilot. The identity of this pilot is shrouded in secrecy as all Shadow-class full conversion cyborgs have had their personnel records erased. This pilot is believed to be the same one that was involved in the long abandoned Tetsujin Project.
