Designed during the last days of the Star League, the '''''Crab''''' proved a superior unit before being almost forgotten during the [[Succession Wars]]. Following the recovery of the [[Helm Memory Core]], [[Cosara Weaponries]] was able to restart production in [[3050]]. It has a maximum speed of 86.4 km/h that allows it to avoid most heavy and assault [['Mech]]s but leaves it vulnerable to machines of its own weight class. Born to be a guerrilla unit, the ''Crab'' is a heavily armed and armored medium 'Mech known for its logistical durability. The ''Crab'' also suffers from an extremely steep heat curve. While the ''Crab'' has sufficient standard heat sinks to facilitate repeating firings of its twin Large Lasers, adding its supplemental weapons quickly overheats the machine.

Designed in [[Introduction Year::2719]] during the last days of the [[Star League]], the '''''Crab''''' was built as a medium-weight raider and guerrilla fighter for the [[Star League Defense Force]]. Although lacking [[jump jets]], it possessed good overland speed and its all-energy weapons payload was suitable for long-range missions without the prospect for resupply. The ''Crab'' also boasted a highly advanced communications system, the [[Dalban Series K]], and was built mostly with proven parts that were easy to maintain. The term "''Crab'' walk" soon became synonymous with easy duty, since technicians spent less than half the time maintaining the ''Crab'' than with other 'Mechs of the same weight class. So popular was the ''Crab'' that many believed it was likely to become the standard medium 'Mech of the SLDF. Unfortunately the [[Amaris Civil War]] and the dissolution of the Star League put an end to any future plans for the ''Crab''.<ref name=TRO2750>''Technical Readout: 2750'', p. 30-31</ref><ref name=TRO3025r>''Technical Readout: 3025 Revised'', p. 56-57</ref><ref name=TRO3039>''Technical Readout: 3039'', p. 258-259</ref>

Less than 1,000 ''Crabs'' had been produced when the [[Succession Wars (History)|Succession Wars]] began. [[Cosara Weaponries]]' factory on [[Northwind]] was practically destroyed in [[2786]], one of many strategic targets attacked in the opening salvos of the [[First Succession War]]. Although dedicated technicians were able to keep portions of the assembly line open, producing what spare parts they still could to rebuild damaged ''Crabs'', the technology used for both the original's advanced armor plating and communications system became [[lostech|lost]]. Designated as CRB-20 models, these ''Crabs'' were only slightly inferior to the original; with the destruction of the military infrastructure necessary for the Dalban Series K's more advanced functions to work, its replacement by lesser systems ironically became less of an issue. By the end of the [[Fourth Succession War]] 100 or so ''Crabs'' were still active in the [[Inner Sphere]] and all were CRB-20s.<ref name=TRO3025r/><ref name=TRO3039/><ref name=TRO3050u>''Technical Readout: 3050 Upgrade'', p. 198-199</ref>
−
The ''Crab'' carries two arm mounted RamTech 1200 [[Large Laser]]s. They are backed up by a Ceres Arms [[Medium Laser]] and an Exostar [[Small Laser]]. While this is a high heat design, the all laser configuration does lend itself to guerrilla warfare as it cannot run out of ammunition.
+
 
 +
Unbeknownst to many, [[ComStar]] had secreted away massive stockpiles of Star League technology and 'Mechs, including the ''Crab''. When it came time to form their own military, original CRB-27 ''Crabs'' were used to outfit the [[Com Guards]], while at the same time gifting downgraded CRB-20s to the [[Draconis Combine]] during the [[War of 3039]] as part of [[Operation Rosebud]]. Concurrently, the discovery of the [[Helm Memory Core]] allowed the refit line on Northwind to start upgrading the remaining downgraded ''Crabs'' to their original specification. Unknown to anyone in the Inner Sphere was the continued existence of the ''Crab'' in the arsenal of the [[Clans]], although by the time of the [[Clan Invasion]] these had been relegated to second-line and garrison units. Eventually Cosara Weaponries was able to restart production of the original ''Crab'' in the [[Production Resumed::3050]]s and brand-new variants began turning up. Among these were new CRB-30s built by ComStar, later acquired by the [[Word of Blake]], which made use of new [[C3]] technology; it was also rumored ComStar sold these models to the [[Free Rasalhague Republic]]. During the [[Jihad]] the Word of Blake managed to capture the Northwind factory and begin producing their own radical variant known as the CRB-45.<ref name=TRO3039/><ref name=TRO3050u/>

 +
==Weapons and Equipment==
 +
The ''Crab'' carries two [[RAMTech 1200]] [[large laser]]s, each housed in the claw and forearm of either arm. While excellent weapons, they are quite delicate with the focusing mirrors liable to be knocked out of alignment if used in hand-to-hand combat; fixing them requires the pilot to leave their cockpit and stick their head up into each arm's elbow to make the necessary adjustments. Backing up the large lasers is a [[Ceres Arms]] [[medium laser]] in the center torso, well-protected from the [[fusion engine]] and with easy access to the 16 [[heat sink]]s, and an [[Exostar]] [[small laser]] in the head, a last-resort weapon more suitable for fighting [[infantry]] and rioting citizens. Nine tons of [[ferro-fibrous]] armor provides good protection for its size as even the weakest locations, the left and right torso, can each survive a shot from a [[PPC]]. Originally lacking hand actuators, Cosara later provided a refit kit to install one in either or both arms.<ref name=TRO2750/><ref name=TRO3025r/><ref name=TRO3039/><ref name=TRO3050u/>
 +
 
 +
The centerpiece of the ''Crab'' is its [[Dalban Series K]] communications system with an integrated [[650 RND]] targeting-tracking system. It monitors all radio and short-wave bands to not only determine the 'Mech's exact location on a world but the approximate location of other units, friend or foe, without the use of [[satellite]]s. The system was smart enough to predict enemy movements and project a path towards a given location while avoiding their notice. However, in contrast to the rest of the 'Mech, this system was extremely hard to maintain, even breaking down when not in combat. As the Succession Wars dragged on, only the most elite and prestigious mercenary and House units could maintain the system, and when the last living Series K-certified technician died it soon became a matter of guesswork.<ref name=TRO2750/><ref name=TRO3025r/><ref name=TRO3039/>
 +
 
 +
The other notable feature of the ''Crab'' is its ejection seat, which performs in two different modes. When an explosion is imminent, the top hatch is blown off and the seat ejected up through the roof as commonly seen in other 'Mechs, with seat stabilization thrusters providing a controlled fall some 200 meters away. If more time is allowed, then the seat will instead rotate 90° and eject the pilot out the back of the 'Mech. This is a much briefer and gentler experience for the pilot, with their seat landing some 50 to 90 meters behind the ''Crab''.<ref name=TRO2750/><ref name=TRO3025r/>

*CRB-20 - The CRB-20 is a downgrade of the CRB-27 ''Crab'' that was given to the [[DCMS]] in preparation for the [[War of 3039]] by [[ComStar]] as part of [[Operation Rosebud]]. The only major modification to the design is the use of standard armor which reduced the overall protection on the ''Crab''.<ref name=RS3039>''Record Sheets: 3039'', p. 122</ref> BV (1.0) = 921<ref name=CO124>''Combat Operations'', p. 124</ref>, BV (2.0) = 1,143<ref name=RS3039 />

*; CRB-20 : The CRB-20 is a downgrade of the CRB-27 ''Crab'', first sighted in [[2810]]. The only major modifications to the design is the use of [[standard armor]], which reduced the overall protection on the ''Crab'', and the replacement of its electronic systems with more reliable off-the-shelf models.<ref name=TRSWp80f /> When ComStar gifted their ''Crabs'' to the Draconis Combine they replaced the original components with a [[Garret T-11b]] communications system and a [[Garret D2j]] targeting and tracking system.<ref name=TRO3039/><ref name=RS3039>''Record Sheets: 3039'', p. 122</ref> BV (1.0) = 921,<ref name=CO124>''Combat Operations'', p. 124</ref> BV (2.0) = 1,143<ref name=RS3039 />

*CRB-30 - The CRB-30 is a complete rework of the CRB-27 ''Crab''. To start, the standard engine has been replaced with an [[Fusion Engine - XL|ExtraLight]] model. The CRB-30 puts this free weight to good use by replacing the twin Large Lasers with a pair of [[ER PPC]]s and upgrading the Medium and Small Lasers to an [[ER Medium Laser]] and an [[ER Small Laser]]. The standard [[heat sinks]] have all been replaced with double heat sinks, though two have been removed, so the PPCs must use [[volley fire]].

+
*; CRB-27sl : Another ''Crab'' variant used by the Star League, the 27sl uses an [[XL engine]] with 14 [[double heat sink]]s. The [[large laser]]s and [[medium laser]] are traded out for two [[large pulse laser]]s and a [[medium pulse laser]], and the [[small laser]] replaced by a medium laser. To improve mobility, five [[jump jet]]s were added for a 150 meter jumping range.<ref>''Era Report: 2750'', p. 135</ref> BV (2.0) = 1,309
  
−
*CRB-45 - This variant fielded by [[Word of Blake]] makes use of three [[Light PPC]]s and an [[ER Large Laser]], making the ''Crab'' into a direct-fire support 'Mech. The -45 incorporates enough heat sinks to combat all heat the machine is capable of producing. The engine was upgraded to allow speed of up to 96 km/h. This came at a slight decrease in armor, though the use of a [[Heavy Ferro-Fibrous]] weave helped make up most of the difference.

*; CRB-30 : The CRB-30 is a complete rework of the CRB-27 ''Crab'' introduced in [[3061]]. To start, the standard engine has been replaced with an [[extralight]] model. The CRB-30 puts this free weight to good use by replacing the twin [[large laser]]s with a pair of [[ER PPC]]s and upgrading the [[medium laser]] and [[small laser]] to an [[ER medium laser]] and an [[ER small laser]]. The standard [[single heat sink]]s have all been replaced with [[double heat sink]]s, though two have been removed, so the PPCs must use [[volley fire]].

*; CRB-54 : This ''Crab'' variant uses a [[composite internal structure]] and a 350-rated [[XXL fusion engine]] to reach speeds of 110 km/h. A [[supercharger]] allows it to sprint at 140 km/h, which is good for leaving the field when its armor is breached. Main firepower comes from a pair of [[plasma rifle]]s supported by an [[ER medium laser]] and an [[ER small laser]].<ref name=rg6p13>''Recognition Guide: ilClan, vol. 5, p. 13</ref> BV (2.0) = 1,964<ref>''Recognition Guide: ilClan, Vol. 5'', p. 18</ref>

Description[edit]

Designed in 2719 during the last days of the Star League, the Crab was built as a medium-weight raider and guerrilla fighter for the Star League Defense Force. Although lacking jump jets, it possessed good overland speed and its all-energy weapons payload was suitable for long-range missions without the prospect for resupply. The Crab also boasted a highly advanced communications system, the Dalban Series K, and was built mostly with proven parts that were easy to maintain. The term "Crab walk" soon became synonymous with easy duty, since technicians spent less than half the time maintaining the Crab than with other 'Mechs of the same weight class. So popular was the Crab that many believed it was likely to become the standard medium 'Mech of the SLDF. Unfortunately the Amaris Civil War and the dissolution of the Star League put an end to any future plans for the Crab.[4][5][6]

Less than 1,000 Crabs had been produced when the Succession Wars began. Cosara Weaponries' factory on Northwind was practically destroyed in 2786, one of many strategic targets attacked in the opening salvos of the First Succession War. Although dedicated technicians were able to keep portions of the assembly line open, producing what spare parts they still could to rebuild damaged Crabs, the technology used for both the original's advanced armor plating and communications system became lost. Designated as CRB-20 models, these Crabs were only slightly inferior to the original; with the destruction of the military infrastructure necessary for the Dalban Series K's more advanced functions to work, its replacement by lesser systems ironically became less of an issue. By the end of the Fourth Succession War 100 or so Crabs were still active in the Inner Sphere and all were CRB-20s.[5][6][7]

Unbeknownst to many, ComStar had secreted away massive stockpiles of Star League technology and 'Mechs, including the Crab. When it came time to form their own military, original CRB-27 Crabs were used to outfit the Com Guards, while at the same time gifting downgraded CRB-20s to the Draconis Combine during the War of 3039 as part of Operation Rosebud. Concurrently, the discovery of the Helm Memory Core allowed the refit line on Northwind to start upgrading the remaining downgraded Crabs to their original specification. Unknown to anyone in the Inner Sphere was the continued existence of the Crab in the arsenal of the Clans, although by the time of the Clan Invasion these had been relegated to second-line and garrison units. Eventually Cosara Weaponries was able to restart production of the original Crab in the 3050s and brand-new variants began turning up. Among these were new CRB-30s built by ComStar, later acquired by the Word of Blake, which made use of new C3 technology; it was also rumored ComStar sold these models to the Free Rasalhague Republic. During the Jihad the Word of Blake managed to capture the Northwind factory and begin producing their own radical variant known as the CRB-45.[6][7]

Weapons and Equipment[edit]

The Crab carries two RAMTech 1200 large lasers, each housed in the claw and forearm of either arm. While excellent weapons, they are quite delicate with the focusing mirrors liable to be knocked out of alignment if used in hand-to-hand combat; fixing them requires the pilot to leave their cockpit and stick their head up into each arm's elbow to make the necessary adjustments. Backing up the large lasers is a Ceres Arms medium laser in the center torso, well-protected from the fusion engine and with easy access to the 16 heat sinks, and an Exostar small laser in the head, a last-resort weapon more suitable for fighting infantry and rioting citizens. Nine tons of ferro-fibrous armor provides good protection for its size as even the weakest locations, the left and right torso, can each survive a shot from a PPC. Originally lacking hand actuators, Cosara later provided a refit kit to install one in either or both arms.[4][5][6][7]

The centerpiece of the Crab is its Dalban Series K communications system with an integrated 650 RND targeting-tracking system. It monitors all radio and short-wave bands to not only determine the 'Mech's exact location on a world but the approximate location of other units, friend or foe, without the use of satellites. The system was smart enough to predict enemy movements and project a path towards a given location while avoiding their notice. However, in contrast to the rest of the 'Mech, this system was extremely hard to maintain, even breaking down when not in combat. As the Succession Wars dragged on, only the most elite and prestigious mercenary and House units could maintain the system, and when the last living Series K-certified technician died it soon became a matter of guesswork.[4][5][6]

The other notable feature of the Crab is its ejection seat, which performs in two different modes. When an explosion is imminent, the top hatch is blown off and the seat ejected up through the roof as commonly seen in other 'Mechs, with seat stabilization thrusters providing a controlled fall some 200 meters away. If more time is allowed, then the seat will instead rotate 90° and eject the pilot out the back of the 'Mech. This is a much briefer and gentler experience for the pilot, with their seat landing some 50 to 90 meters behind the Crab.[4][5]

Variants[edit]

  • CRB-20 
    The CRB-20 is a downgrade of the CRB-27 Crab, first sighted in 2810. The only major modifications to the design is the use of standard armor, which reduced the overall protection on the Crab, and the replacement of its electronic systems with more reliable off-the-shelf models.[1] When ComStar gifted their Crabs to the Draconis Combine they replaced the original components with a Garret T-11b communications system and a Garret D2j targeting and tracking system.[6][8] BV (1.0) = 921,[9] BV (2.0) = 1,143[8]
  • CRB-45 
    This variant, fielded by Word of Blake and first spotted in 3070, makes use of three light PPCs and an ER large laser, turning the Crab into a direct-fire support 'Mech. The 45 incorporates 15 double heat sinks to combat all heat the machine is capable of producing, while a larger 300-rated XL engine allows speeds of up to 96 km/h. This came at a slight decrease in armor, though the use of a heavy ferro-fibrous weave helped make up most of the difference. A seemingly-standard C3i computer allows this design to share target data with other like-equipped units.[1][17] BV (2.0) = 1,342
  • CRB-C 
    The CRB-C Crab is a minor update of the design modified to include a C3 slave unit. Introduced by the Draconis Combine in 3056, this Crab makes space for the C3 unit by removing the medium laser.[1][20] BV (1.0) = 950 (C3: 90),[9] BV (2.0) = 1,135

From MechWarrior Online:

  • CRB-FL Florentine 
    While all indications are that Judith Faber, Blake's Wrath agent Rapier, piloted a standard CRB-27 during the Battle of Tukayyid, MechWarrior Online paints a wildly different picture in their version of her 'Mech. Named Florentine, this variant is a virtual mini-King Crab, mounting an UAC/5 in each arm supported by a left-torso mounted LRM-5 and a right-torso mounted medium laser. Carrying one ton of missiles and three tons of autocannon ammunition, the Florentine's weapon loadout is made possible through use of a 250-rated XL engine and an endo steel frame.[21]
