Description[edit]

The Orion was built in 2456 as the first true heavy BattleMech. Originally designed for the Terran Hegemony to maintain its dominance and built on Hesperus II, the Orion is a dependable workhorse design that can handle almost any combat role, thanks to its mix of long- and short-range weaponry and its respectable armoring. After the K model was introduced in 2525 the 'Mech first saw combat during the Reunification War and continued to serve the Star League and its Member States for the next few centuries. Perhaps its most famous role was as the personal 'Mech of Aleksandr Kerensky during the Amaris Civil War, and it was while piloting his Orion that the general kicked down the palace doors to take the Usurper prisoner.[4][5]

After the fall of the Star League Kali Yama Weapons Industries took over production of the Orion, building new models from their factories on Kalidasa. This left the Free Worlds League as the only producer of new Orions during the Succession Wars, although the other Successor States were capable of building spare parts to repair their 'Mechs, and meant the Free Worlds League Military was the largest Orion user. When Kali Yama merged to create the Kali Yama - Alphard Trading Corporation Orion production was started up on Kendall as well.[4][5] The League's dominance in new Orions began to change during the Clan Invasion when the Successor States met on Outreach and agreed to work together to combat the Clans. Kali Yama/ATC was among those companies which would sell war materiel, including the Orion, to the other States undergoing Clan attacks. In spite of the design's age it still finds itself utilized extensively on the modern battlefield and new variants continue to be produced.[6]

Weapons and Equipment[edit]

The Orion has a varied weapons mix. The 'Mech's primary long-range weapon is a KaliYama Death Bloom LRM-15 launcher mounted in the left torso along with two tons of reloads. While an accurate weapon useful against both land and air targets the system's control cables travel through a narrow area in the shoulder. This subjects the area to excessive heat, which can cause either the weapon or actuator to shut down. For intermediate ranges, the Orion carries a KaliYama Class 10 Autocannon/10 in its right torso with two tons of ammo. For centuries the ammunition feed to the cannon suffered regular jamming unless pilots loaded nineteen salvos instead of the full twenty in the ammunition clip. This defect was eventually solved in the 3030s by Norse-Storm Technologies Inc., although the fact that the weapon's placement limits right-arm movement and can be knocked out of alignment if accidentally struck couldn't be helped. Finally, for close-range combat, the Orion has an Irian Weapons Works Class 4 SRM-4 launcher in the left arm fed by a one-ton bin in the left torso and two Irian Weapons Works Medium Lasers in both arms. Six tubes surround the left-arm laser although only four of them are used to launch SRMs; the bottom two instead serve as hook-up points for connecting with Coolant Trucks.[4][5]

Carrying fourteen and a half tons of armor gives the Orion superior protection to most other heavy 'Mechs, with its chest and rear torso being the most and least protected respectively. Combined with an average cruising speed of 43.2 km/h the 'Mech is a challenging opponent. Only ten heat sinks mounted in the engine leaving the Orion more vulnerable to overheating but experienced pilots know to avoid this issue by alternating weapon firings. Technicians love the Orion, because its spacious interior makes performing repairs and maintenance far easier than many other 'Mechs; this is also the reason for the design's longevity.[4][5]

Variants[edit]

  • ON1-C 
    The original Orion 'Mech as it was first commissioned lacked an LRM launcher and used an Autocannon/5 in place of the AC/10.[5]
  • ON1-M 
    The M variant is an upgrade using Star League technology first fielded in 3049. Replacing the standard engine with a Hermes 300 XL Engine and shaving off a half-ton of armor allows the 'Mech to retain the same speed while mounting a number of upgrades. The LRM-15 has been replaced with an Kali Yama Weapons Industries Type V LRM-20 launcher and the Autocannon/10 has been upgraded to an Kali Yama Weapons Industries LB-X Autocannon/10. In addition a Octagon Missile Magnet Narc Missile Beacon launcher was added to the center torso along with two tons of reloads, while the SRM-4 and the medium lasers have been retained. The use of eleven double heat sinks also solves any problems associated with overheating. This variant was first used in combat during Operation Guerrero when the FWL attempted to liberate worlds previously ceded to the Federated Commonwealth, with it seeing its first use against the Clans during the Jade Falcon Incursion.[6] BV (1.0) = 1,192[7], BV (2.0) = 1,414[8]
  • ON1-MA 
    This is one of the many minor variants of the ON1-M model introduced in 3052. The Narc Missile Beacon is removed to allow a larger SRM-6 to replace the four pack. Both missile racks also have Artemis IV Fire Control System to increase accuracy. Finally, medium pulse lasers are mounted in place of original mediums.[6] BV (2.0) = 1,501[9]
  • ON1-MC 
    A third minor variant of the ON1-M also introduced in 3058. The designers removed both missile racks and Narc launcher to make room for Medium Range Missile. In place of the LRM-20 is a MRM-20 while a larger MRM-30 is crammed in the torso where the SRM-4 formerly sat. Enough room is left to add a head-mounted C3 Slave Unit. This variant was much-used by the Draconis Combine.[6] BV (2.0) = 1,501[11]
  • ON1-MD 
    Another minor variant of the ON1-M fielded in 3062. A simple weapon swap, the LB-X Autocannon/10 is exchanged for a Rotary Autocannon/5. BV (2.0) = 1,597[12]
  • ON1-V 
    A basic modification of the ON1-K first seen in 2799, the ON1-V removes three tons of armor to make room for an additional SRM-4 launcher in the right arm in order to give the Orion even greater close-range damage capability. BV (1.0) = 931[7], BV (2.0) = 1,298[13]
  • ON1-VA 
    A modification along the same lines as the ON1-V introduced in 2901 the VA model removes the LRM launcher, rather than removing armor, to add the second SRM-4 launcher, sacrificing some long-range damage capabilities for superior close-combat capabilities. BV (1.0) = 1,111[7], BV (2.0) = 1,328[14]
  • ON2-M 
    The 2M is another upgrade of the Orion using Star League technology. Built in 3063 the 'Mech uses an Endo Steel chassis and utilizes ten double-strength heat sinks to save weight and for their greater heat-dissipation ability. For long-range combat, the ON2-M is armed with a Gauss Rifle as well as an LRM-15 linked to an Artemis IV FCS for increased accuracy. For closer ranges, the 'Mech has three medium pulse lasers. The ON2-M is armored with twelve and a half tons of Ferro-Fibrous armor. BV (1.0) = 1,633[7] (1,624)[15], BV (2.0) = 1,828[16]
  • ON3-MX 
    This experimental Orion 3100 variant was introduced in 3075 as "a BattleMech for the thirty-second century"; although its flaws prevented any immediate production it gave Kali Yama valuable experience and a few prototypes were sold. It is equipped with an experimental Extended LRM-10 and Improved Heavy Gauss Rifle. Three tons of ammunition feeds the LRM launcher while the iHGR gets four tons of ammunition. For close in work, this Orion variant has an ER Medium Laser in each arm. To provide room for these weapons, the 'Mech has an XL Engine, standard armor, and standard internal structure, and only the ELRM ammo is protected by CASE. BV (2.0) = 1,849[17]
  • ON3-M 
    This version introduced in 3083 was based on the earlier ON3-MX, although it addresses some of the shortcomings of that 'Mech and shares many of the same features as the ON1-M. Providing a more balanced weapon suite it still carries an Extended LRM-15 with four tons of ammo and an ER medium laser in each arm but instead uses a Grand Slam Gauss Rifle with two tons of ammo in the right torso. It also uses CASE II to protect the ammunition and has a head-mounted TAG system to call in artillery. Initial feedback and advanced orders convinced Kali Yama to switch most of their Orion production lines over to making the ON3-M in 3086, but were soon set back a few years later when pressure from the Republic of the Sphere caused the Federated Suns to cancel their order. The company has seen sold the 'Mech at below-market prices and suffered financial hardship. BV (2.0) = 1,826[18][19]
  • Dual Cockpit refits: The Orion is one of the Free Worlds League's preferred 'Mechs on which to install Dual Cockpits. Standard refits usually install the Dual Cockpit on a ON1-V or ON1-M, requiring the removal one ton of SRM ammunition.[citation needed]

  • ON1-P "Protector
    A late 3040's era homage to General Keresnky's custom variant, the "Protector" carries an almost identical weapons loadout, the only notable difference is its use of a standard PPC in the place of the still-lostech snub-nosed version, dropping the CASE and volume of Ferro-fibrous armor carried to free up the weight for the heavier weapon. This variant was designed for MechWarrior Online.

Notes[edit]

Though most of the artwork shows that the SRM-4 of the standard variant is mounted in the Orion's left arm, according to the official record sheets and TRO: 3039 it is installed in the left torso. It is unclear if this is intentional or an error that never was fixed.
