Built in 2492, the Griffin was originally classified as a heavy BattleMech, filling in the weight gap between mammoth machines like the Mackie and smaller recon 'Mechs like the Wasp, and intended for close assaults. Combining tremendous speed and firepower in one frame the Griffin briefly dominated in this role before being superseded by larger and better-equipped 'Mechs. However the Griffin was very popular among commanders and pilots alike and so Earthwerks Incorporated kept it in production, this time reclassified as a medium 'Mech and tasked with long-range fire support for medium lances. In this capacity the Griffin has excelled, combining good striking power, endurance and speed, with its only major weakness being a lack of close-range defensive weapons.[4][2]

During the Succession Wars the Griffin could be found in almost every unit of all the Great Houses, thanks in part to its diverse number of manufacturers. Besides being constructed from Earthwerks' factory on Keystone the Griffin was later acquired and built by Defiance Industries (Hesperus II), Kallon Industries (Talon), Brigadier Corporation (Oliver), and Norse BattleMech Works (later Victory Industries, Marduk). It was even manufactured in the Periphery by Vandenberg Mechanized Industries on Illiushin.[5] Only the Capellan Confederation lacked a means of building the 'Mech, although they made up for it by purchasing a limited number from the Taurian Concordat.[2] During the Fourth Succession War some of these manufacturers exchanged hands, with the Draconis Combine capturing Marduk from the Federated Suns and the Lyran Commonwealth taking Oliver from the Free Worlds League. This exchange also happened to coincide with several new variants being designed to exploit recently-recovered lostech. As such variants meant specifically for either Houses Kurita, Marik or the Federated Commonwealth found their way into the arsenals of all of them. During the Clan Invasion these manufacturers produced the new variants to meet the Clan threat while Vandenberg Industries continued to build original GRF-1N Griffins.[5]

When Vicore Industries began shopping around its "Project Phoenix" initiative, Defiance and Kallon Industries signed on to begin producing the completely redesigned GRF-6S Griffin. Victory Industries later signed up as well after the legal battle between Wolf's Dragoons and the Lyran Alliance saw the famous mercenary group selling its Light Fusion technology to both the Draconis Combine and Free Worlds League. The League designed a native update to the Griffin while ComStar had their own built as well which, ominously, soon began appearing in the ranks of the Word of Blake Militia.[6] The Griffin would continue to remain a staple of the battlefields of the Inner Sphere during the maelstrom of the Jihad, the era of the Republic of the Sphere and the rise of the ilClan, with models still in production within the Free Worlds League and the Wolf Empire.[7]

Weapons and Equipment[edit]

The primary weapon on the Griffin is a Fusigon PPC in the right arm. The PPC allows the Griffin to work in a long-range fire support role and is backed up by a Delta Dart LRM-10 launcher mounted in a drum over the right shoulder. The LRM launcher also gives the Griffin some indirect fire support capabilities and the two tons of reloads in the right torso allows for good endurance. The Achilles' heel of the design is its lack of short-range weapons, for when an enemy is capable of closing ranges and engaging in close quarters combat, and the fact that all of its weapons are located on the right side. The 'Mech is however equipped with two powerful battlefists for hand-to-hand combat.[4][2]

The massive and efficient fusion engine of the Griffin, giving it a cruising speed of 57.1 km/h, combined with five jump jets occupying the rear torso areas for a total jumping distance of 150 meters, is what distinguishes it from other medium 'Mechs and has kept the Griffin in the game over the centuries. Unfortunately, like most other early 'Mechs, the Griffin suffers from insufficient heat capacity with only twelve heat sinks installed. The result is that Griffin pilots, lacking the ability to do both, must choose at the outset of a fight whether to engage or withdraw.[4][2]

Nine and a half tons of armor plating compares quite favorably to many other medium 'Mechs, although as is often the case the Griffin will find itself in combat with larger 'Mechs. For this reason, two pairs of false armor baffles were added to the 'Mech, one on its shoulders providing limited protection to the LRM launcher and cockpit, and a smaller pair on the legs protecting the knees joints.[4]


  • GRF-1A 
    The original Griffin produced by Maxwell Manufacturing, Inc. weighed sixty tons (thus technically falling into the Heavy category of BattleMechs) and used primitive components. It could reach a top speed of 64 km/h and cover ninety meters with Prototype Jump Jets. It also carried a Prototype PPC and a single LRM-5 with a ton of ammunition. It was protected by fourteen and a half tons of Primitive Armor and equipped with eleven single heat sinks. A Primitive Cockpit was provided for the pilot.[8] BV (2.0) = 1,024[9]
  • GRF-1S 
    The 1S Griffin was for many years the only production variant of the Griffin, built for House Steiner by Defiance Industries starting in 2857. It attempted to rectify the 1N's lack of close range weapons by removing the PPC and in its place mounting a Defiance B3L Large Laser and two Defiance B3M medium lasers. The LRM-10 was also replaced with an Coventry Five-Tube LRM-5 and one ton of reloads in the right torso. To further help manage the heat load, the 'Mech also added four additional heat sinks to the design. This new arrangement essentially transformed the long-range support 'Mech into a medium-range brawler.[4][2][11] BV (1.0) = 1,061, BV (2.0) = 1,253[12][11]
  • GRF-2N 
    The SLDF's Royal Griffin was introduced in 2751 and mounted an ER PPC, two SRM-6 launchers, and a Guardian ECM Suite. The heat sinks were upgraded to double-strength models and the ammo was protected by CASE. To fit all this, the armor was changed to Ferro-Fibrous and the chassis was made of Endo Steel. Disappearing during the Succession Wars until a Jihad era return thanks to the discovery of the New Dallas Memory Core, the Clans also retained a number of original models among their solahma forces.[7] BV (2.0) = 1606[13][14]
  • GRF-3M 
    The 3M Griffin was an upgraded version of the design built for House Marik by Earthwerks and Brigadier Corps starting in 3049. With production lines on Keystone and Oliver this variant sought to enhance the original's long-range capabilities. The engine was exchanged for a Hermes 275 extralight model and carried fourteen double heat sinks to improve heat management. The normal PPC was replaced by a Fusigon Longtooth ER PPC, for longer reach at the expense of more heat, and the LRM launcher had been upgraded to a Doombud LRM-20 launcher, for more indirect fire support capabilities. Finally a ChisComp Small Laser was mounted in the left torso, with two tons of CASE protected LRM reloads. While intended for the Free Worlds League Military the capture of Oliver by FedCom forces meant the 3M also appeared in large numbers in the Armed Forces of the Federated Commonwealth.[5] BV (1.0) = 1,440, BV (2.0) = 1,521[15]
  • GRF-3N 
    The 3N Griffin is a 3150 era model produced at the Earthwerks Tiber plant for the Free Worlds League, engaging its foes at range with a Fusigon Longtooth ER PPC and a Artemis IV-enhanced Delta Dart II Enhanced LRM-10 Launcher with two tons of reloads. Clad in ten tons of Valiant Chainmail Ferro-Fibrous armor and built around an Endo Steel frame, the use of a standard 275 rated engine, eleven double heat sinks, jump jets and CASE II provide the 3N impressive survivability. BV (2.0) = 1,560[7]
  • GRF-4N 
    This Griffin was introduced to the Taurian Concordat in 3083. It carries a Plasma Rifle and three ER medium lasers. It also has a higher top speed than its inspiration and can jump farther as well.[17] BV (2.0) = 1,591[18]
  • GRF-5L 
    This variant, introduced in 3070, uses an XL engine to max out armor protection at eleven and a half tons of Stealth Armor. As with all Stealth-equipped designs, the 5L used a Guardian ECM Suite. It was armed with a Plasma Rifle and an MML-5, which could threaten enemies at all ranges. Three medium lasers provided added short-range firepower. Fourteen double heat sinks kept the 'Mech relatively cool, even when the Stealth Armor was active. BV (2.0) = 1,781[19]
  • GRF-5M 
    The 5M variant of the Griffin was designed in 3066 with a distinctive flair for the Free Worlds League. Unlike other "Phoenix" 'Mechs it was powered by an extralight engine and carried, as its primary weapon, a Light Gauss Rifle. This was backed up by an LRM-10 launcher and a small laser for close range work. The variant utilized double heat sinks and also carried ten and a half tons of armor. BV (1.0) = 1,108, BV (2.0) = 1,224[20]
  • GRF-6CS 
    A variant of the 6S developed in 3067 for the Com Guards only to also fall into hands of the Word of Blake, the 6CS used an Endo Steel frame and was powered by an extralight engine. The 'Mech's primary weapons were an ER PPC and an LRM-15 launcher linked to an Artemis IV fire control system. The 6CS carries two ER medium lasers for short range engagements, and has an advanced electronics warfare suite, consisting of a Guardian ECM Suite and a C3i computer, to allow it to share targeting telemetry with friendly units. BV (1.0) = 1,469, BV (2.0) = 1,695[21]
  • GRF-6S 
    The Lyran 6S Griffin was built in 3066 using an Earthwerks GRF Endo Steel chassis and mounted a Defiance 275 light fusion engine for power. This allowed the 6S model to carry a Defiance 1001 ER PPC in the right arm, a Coventry StarFire LRM-15 over the right shoulder with Artemis IV, and two RAMTech 1500Z ER medium lasers, one in the center torso and one in the left arm. It carried twelve tons of Starshield A armor plating using layered sections at steeper angles, which allowed it to withstand more attacks than the 6CS, but only ten double heat sinks. Two tons of LRM reloads were mounted in the right torso and protected by CASE. Although still carrying the five Rawlings 55 jump jets and Neil 6000 communications system of the original model, the targeting-tracking system was updated to a RCA Instatrack Mk X and, perhaps most importantly, the cockpit was renovated for additional comfort and incorporate a Full-Head Ejection System.[6] BV (1.0) = 1,461, BV (2.0) = 1,781[22]
  • GRF-6S2 
    This variant of the Griffin was based on the 6S. By dropping one of the ER medium lasers, the Artemis system, and using a Clan-spec LRM-15, engineers found enough room to add a C3 Boosted Slave and a Targeting Computer. CASE II protects the LRM ammunition. BV (2.0) = 1,870[23]

Custom Variants[edit]

  • GRF-1E Griffin Sparky 
    The personal ‘Mech of Elle Bennett of the Fifth Donegal Guards, prior to the War of 3039 she had replaced the LRM launcher of her Griffin with five medium lasers, one mounted in each torso, one beside the PPC and two in Sparky's left arm. The additional weight saved goes towards an extra heat sink and an additional ton of armor.[2] BV (2.0) = 1,449[25]
  • GRF-1E2 Griffin Sparky 2.0 
    The personal ‘Mech of Leftenant Natasha Ergen of the Fifth FedCom RCT, her stock Griffin had been refitted with ferro-fibrous armor and a light fusion engine. Fourteen double heat sinks and a targeting computer allowed Ergen to obtain maximum effect from an all-energy weapons array consisting of an ER PPC, two standard medium lasers mounted one per side torso alongside three ER medium lasers, one mounted in each torso component. BV (2.0) = 1,862[26]
  • GRF-6S Griffin Francine 
    A vintage Griffin refitted to the 6S standard and beyond with captured Word of Blake technology, when Francine rescued the Black Widow Company at the Royal Pass of the Ridges in 3070, her 'Mech carried half a ton less armor and swapped the 6S's ER PPC for an advanced Snub-Nose PPC as well as adding an extra ER medium laser to the left arm and a rear-facing small laser. BV (2.0) = 1,820[27]

Related BattleMechs[edit]

  • GRF-2N Super Griffin - Although it carries the designation GRF-2N, this is actually a new 60-ton 'Mech design based on the regular Griffin, in a similar fashion to IIC evolution of existing designs (albeit not with Clan-level technology).
  • Griffin IIC - The Griffin was one of the 'Mechs taken on the Exodus by the SLDF, following the collapse of the Star League. Eventually, the model was redesigned to use exclusive Clan technology and the Griffin IIC was created. BV (1.0) = 1,492, BV (2.0) = 1,608
