Philadelphia-class orbital weapon platform

The Philadelphia-class orbital weapon platform is a class of space station deployed by the UNSC to defend colonies from hostile warships.
== Armament ==
The Philadelphia-class OWP's primary weapon system is a Mark V Heavy Coil Magnetic Accelerator Cannon, which is also mounted aboard Jupiter-class supercarriers. Despite their lower kinetic energy per-shot compared the the Mark VI "super" MAC used on the later Moncton-class platforms, they are nonetheless potent weapons, able to destroy most hostile warships in only a few shots.
