The Celerity is ComStar's attempt at creating an expendable drone reconnaissance BattleMech.

Though ComStar's drone project started immediately after the Battle of Tukayyid, initially utilizing swift ground based Combat Vehicles or VTOLs controlled from a modified Fury-based control hub, in the Jihad years under Precentor Ashok Sethi the project shifted toward an extremely specialized ultralight Four Legged BattleMech platform for the drones.[4] While discontinued after the Jihad, the Blessed Order would also utilize the Celerity during its desperate last stand against the Republic of the Sphere in 3141.[5]

After the Fortress Protocols were activated, the Republic of the Sphere began experimenting with the Celerity as a means of expanding its warfighting technology. They created a true OmniMech version of the Celerity to expand upon its utility and used it extensively on raids across their borders in the Dark Age era, causing endless confusion as to the identity of the parties using them.[1]

Weapons and Equipment[edit]

The lightweight Celerity is built on an Endo Steel frame and is powered by a massive 240 rated XXL Fusion Engine, the bulky engine making the animalistic drone capable of high-speed sprints, further enhanced by the addition of MASC to make it among the fastest ground units in existence.[4]

While not mounting any defensive weaponry, the Celerity's head is equipped with a Full-Head Ejection System and carries a C3i module, mitigating the drone's expendable nature while allowing the drone's data and expensive C3 system to be recovered. This is a good thing given the Celerity's sole single ton of armor and the fragile nature of its XXL Engine and XL Gyro, even a single skid following a misstep would almost cripple the design let alone combat fire on the battlefield.[4]


With its head equipped with a similar modular mounting system as the proto-OmniMech the Mercury, the Celerity was intended to be highly adaptable to variations mounting any number of systems from an ECM Pod, TAG, a standard C3 Slave or even a Booby Trap, though no recorded instances aside from the C3i version were known.[4]

  • CLR-03-O 
    The Republic's OmniMech Celerity removed the C3i system and replaced it with OmniPod space, fitting it with Double Heat Sinks to expand its utility as well as carry an extra half-ton of armor. The Republic's primary Celerity version carries a C3 Slave and TAG. BV (2.0) = 187[6]
  • Alternate Configuration B 
    The Celerity B uses an Angel ECM Suite to disrupt enemy electronics systems. BV (2.0) = 339[8]
  • Alternate Configuration D 
    This configuration is equipped with two ER Flamers. BV (2.0) = 304[10]
  • CLR-04-R 
    This Celerity model uses a smaller engine, limiting it to a top speed of approximately 230 km/h. It also removes the MASC system and some armor to make room for a TSEMP One-Shot. BV (2.0) = 384[12]

Custom Variants[edit]

  • CLR-030MM Rajah 
    Piloted remotely by Rodric Wilhelm, this 'Mech is intended as a "pet" for the Drone Command Console equipped PXH-7KJ Phoenix Hawk Jasmine in the Solaris Games, Rajah is a much cheaper refit of the standard ComStar Celerity, swapping out the XXL engine for a standard 120 engine and removing the MASC. While halving its ground speed, the swap makes it much cheaper to field, handy as it only boasts an extra half-ton of armor with the extra weight going towards three groups of Spikes and a pair of Clan-tech ER Small Lasers, a swap to double heat sinks keeping it cool.
