Crusader

Description
The Crusader was initially designed as a close combat BattleMech for the Star League Defense Force, but soon proved itself to be a very adaptable, multi-role design. This reliable workhorse of the SLDF, while not excelling in any one job, was quite capable of accomplishing just about any mission, whether it be close assault, anti-aircraft, counterinsurgency, or even reconnaissance. Its versatility and large number of manufacturers ensured the Crusader its place as one of the most common heavy 'Mechs in the Inner Sphere.

The Crusader received its baptism of fire during the Reunification War and remained a common fixture in the regiments of the SLDF for many centuries. Even after the fall of the Star League, the various Successor States continued to field large numbers of Crusaders in their armies, thanks to factories located on Tharkad, Oliver, Asuncion and Bernardo. House Steiner in particular was a notable Crusader user, thanks in part to their well-trained technicians who could have damaged units turned around and ready to fight in a single day. A variety of new production variants and field modification kits were turned out for the Crusader after the recovery of the Helm Memory Core, just in time for the Clan Invasion.

In the wake of the Clan Invasion, one of the first new Crusader variants was built by the Cosby BattleMech Research Firm, the (in)famous producer of the No-Dachi 'Mech. Hoping to overcome the lack of prestige of their previous design and win the favor of the Coordinator, the company acquired manufacturing rights to the Crusader through the hostile takeover of another company and unveiled an updated variant of the 'Mech around the start of the FedCom Civil War. Additional variants would continue to be produced in the years since, including models utilized by the Word of Blake during the Jihad.

Weapons and Equipment
The primary long-range weapons on the Crusader were two Magna Longbow-15 LRM-15 launchers, providing the Crusader with long-range fire support capabilities that can compete with the Archer and Catapult. These were supplied by two tons of reloads split between the side torsos. For short-range combat, the 'Mech carried two Harpoon-6 SRM-6 launchers and two Intek medium lasers. Finally, to deter infantry attacks against the Crusader, two M100 heavy machine guns were mounted on the 'Mech. One ton each of SRM and machine gun ammunition was carried in the center torso.

Each arm was equipped with an LRM launcher, laser, and machine gun, while the SRM launchers were built into the legs and mounted at hip height to provide a stable firing location and avoid interference with the LRMs' flight path. Early Crusader models had issues with the arm-mounted launchers and lasers overheating and causing stress to the actuators and internal structure, but this was rectified with the additions of the now-distinctive collars which deflect hot gases away.

The Crusader was well-protected with twelve tons of armor, particularly around the legs, which made it a good hand-to-hand combatant. A thirteen and a half ton fusion engine allowed the Crusader to achieve a decent cruising speed of 43.2 km/h. One disadvantage to the Crusader was its inadequate heat management system, carrying just ten standard heat sinks to handle all the waste heat produced by its weapons and equipment.

Variants

 * CRD-1R : Introduced in Introduction Year::2596, the exact configuration of the original Crusader variant has not been published. However, it was reported by nckestrel on the BattleTech Forums that the MUL notes describe the CRD-1R and -2R as similar, differing primarily by replacing Streak SRM-2s of the CRD-2R (which have yet to be invented) with SRM-4s. Any other differences are currently unknown.


 * CRD-2R : This lostech variant was used by the SLDF's Royal units. It used double heat sinks and utilized an Endo Steel internal structure to save mass. This enabled the addition of Artemis IV Fire Control Systems to the LRM launchers. The SRMs were replaced with four Hawk Streak SRM-2s. All of the ammunition was moved to the side torsos and protected by CASE. BV (2.0) = 1,533


 * CRD-3D : The 3D variant of the Crusader is a simple modification to make the 'Mech's heat load more manageable. Introduced in 2756 and used mostly by the Federated Suns, the two SRM-6 launchers were replaced with two SRM-4 launchers and the machine guns were removed so that the number of heat sinks could be increased by four. BV (1.0) = 1,020; BV (2.0) = 1,338


 * CRD-3K : Another variant of the Crusader concentrating on lessening its heat burden, the 3K was introduced by the Draconis Combine in 2765. It downsized the LRM launchers to LRM-10 models and removed the machine guns to make room for an additional six heat sinks. BV (1.0) = 997; BV (2.0) = 1,290


 * CRD-3L : The 3L variant of the Crusader takes concepts from both the 3D and the 3K models to save weight with a twist. Built for the Capellan Confederation starting in 2753, the 'Mech has removed the LRM-15 and SRM-6 launchers and replaced them with two LRM-10 launchers and two SRM-4 launchers. This frees up room for two additional heat sinks as well as the inclusion of four GM Jetstar jump jets, two each in either side torso, giving it a jumping distance of one hundred and twenty meters. BV (1.0) = 1,032; BV (2.0) = 1,297


 * CDR-4BR : A Star League-tech retrofit of the classic CRD-3R developed by Bander BattleMechs for the mercenary market in 3054, the 4BR switches to double heat sinks and replaces the SRM-6 launchers with a pair of Streak SRM-2s. The weight saved allows an extra ton of LRM reloads for each launcher to be carried, protected by the addition of CASE in each torso. BV (2.0) = 1,407


 * CRD-4D : The 4D variant of the Crusader was a common field modification kit, utilizing Star League technology recovered from the Helm Memory Core, used by both Davion and Liao forces starting in 3049. This variant has had the medium lasers and the SRM-6 launchers removed and in their place has two Streak SRM-2 launchers and two medium pulse lasers mounted, along with three additional heat sinks. Davion 4Ds used Federated SuperStreak launchers and Sutel Precision Line lasers, while the Liao kits contained Hovertec Streak launchers and Magna 400P lasers. BV (1.0) = 1,015;  BV (2.0) = 1,309


 * CRD-4K : A field modification kit based on the 3K variant and introduced for Kuritan forces in 3049, the 4K removes two heat sinks and replaces the two medium lasers of the 3K with Magna 400P medium pulse models. BV (1.0) = 946; BV (2.0) = 1,268


 * CRD-5K : The 5K Crusader was a complete upgrade produced by Cosby BattleMech Research Firm for House Kurita in 3063. The internal structure was replaced with a Foundation CMRFa6 Endo Steel chassis and the engine upgraded to a Nissan 260 XL engine. The 'Mech's armament was completely overhauled as well: the primary weapons were two Shigunga MRM 30 launchers carried in either arm and, as secondary weapons, two Victory 23R medium lasers split between the side torsos and two Victory Heartbeat medium pulse lasers in the center torso. To allow the 5K to share targeting data, it also carried a C3 slave unit, and four tons of MRM reloads was located in the CASE-protected left torso. Finally, to vent waste heat, the 'Mech used eleven double heat sinks and carried twelve tons of Starshield A armor. The electronics were also replaced with a Garret T-11a comm system and Garret D5j T&T system. BV (1.0) = 1,223 (C3: 183); BV (2.0) = 1,463


 * CRD-5M : The 5M was the official production-model upgraded variant of the Crusader for the Free Worlds League, introduced in 3049 and using recovered Star League technology. Though using the same Crucis-B chassis as before the 'Mech was powered by a Hermes 260 XL engine and carried thirteen double heat sinks to vent its heat more efficiently. The 5M was also capable of jumping up to one hundred and twenty meters with its four torso-mounted jump jets. The 'Mech was armed with two Magna Longbow LRM-15 launchers and two Intek medium lasers in its arms, two Hovertec streak SRM-2 launchers mounted in its legs, a Flame Tech flamer and an LFN Lindblad machine gun in its right arm, and an LFN Lindblad Shotgun anti-missile system on its head.  One ton of ammo for the machine gun was carried in the right arm, while two tons of LRM reloads and one ton each for the AMS and Streak launchers were carried in CASE-protected side torsos.  This variant was built for the FWLM from Kallon's factories on Ascuncion and Bernardo, as well as the Brigadier plant on Oliver until that planet was captured by the Federated Commonwealth, after which it began building 5Ms for the AFFC. BV (1.0) = 1,348; BV (2.0) = 1,408


 * CRD-5S : A production-model upgrade of the Crusader utilizing Star League equipment, the 5S was built by TharHes industries on Tharkad for FedCom forces starting in 3049. It varies little from the 3R model, instead removing the machine guns to make room for double heat sinks, CASE to protect the missile reloads, and the addition of a Flamer in the right arm. BV (1.0) = 1,149; BV (2.0) = 1,446


 * CRD-6D : This Kallon variant uses an Endo Steel chassis and 325-rated XL engine to reach a top speed of 86 km/h. Four jump jets allow it to cover 120 meters per jump. LRM-10s and a medium laser are carried in each arm. The SRM-2s in the legs are replaced by SRM-6s. One ton of LRM ammo is carried in each side torso with a ton of SRM ammo is in the center torso. All ammunition is protected by CASE. Fourteen double heat sinks are carried as well. BV (2.0) = 1,498


 * CRD-6M : This variant was produced in the Free Worlds League starting in 3074 during the Jihad. It carries two Streak SRM-4 launchers in the legs, while each arm carries a light PPC and MML-7. The 'Mech's top speed was reduced, so engineers fitted Improved Jump Jets to compensate. BV (2.0) = 1,373


 * CRD-6T : Another Kallon variant has a top speed of 86 km/h thanks to an XL engine. Each arm carries six medium lasers and the leg mounted weapons are a Flamer in each hip mount. Seventeen double heat sinks struggle to keep things cool, but twelve and a half tons of armor protect the 'Mech. A C3 slave unit is mounted in the head, allowing this Crusader to share targeting data. Kallon's engineers were apparently inspired by the Nova OmniMech and the Tessen heavy scout when they created this design. BV (2.0) = 1,890


 * CRD-7D : This Crusader was developed on Wernke. An XL engine with a Supercharger allows it to sprint at speeds of over 100 km/h. Each arm mounts a pair of Medium Re-Engineered Lasers and an MML-3. Another MML-3 is mounted in each hip. An anti-missile system is mounted in the head. Fifteen double heat sinks are fitted and to make room for the weapons engineers used an Endo Steel chassis and Compact Gyro. A ton each of LRM, SRM, and AMS ammunition are carried in a CASE II protected bay in the center torso. BV (2.0) = 1,681


 * CRD-7L : Utilizing some of the newest technology available in the Capellan Confederation, the 7L was built by Tao 'Mechworks in 3067. It used Stealth Armor, making it harder to target. The 'Mech also used double heat sinks and is armed with two LRM-15 launchers, two Streak SRM-4 launchers, and two ER medium lasers. Finally, the 'Mech carried a Guardian ECM suite to allow its Stealth Armor to work. In order to make room, the top speed was lowered to 53 km/h by replacing the engine with a Nissan Fusion 195, though jump jets offset that through increased maneuverability. Despite its Liao origins, half of the first production run was sold to the Word of Blake. BV (1.0) = 1,507; BV (2.0) = 1,860


 * CRD-7M : Derived from the CRD-5M, this configuration carries a Streak SRM-4 in each leg for close in work. The arms each carry a light PPC and an Artemis IV-enhanced MML-7. A head-mounted anti-missile system destroys incoming enemy missiles. The side torsos each carry a pair of Jump Jets, allowing for a 120 meter jump radius, and the XL engine allows a top speed of 64 km/h. Three tons of MML ammo is in the left torso, while Streak, MML, and AMS ammo are in the right torso. All ammunition is stored in a CASE II protected bay. Designers had to use an XL Gyro to free enough weight for this equipment. BV (2.0) = 1,502


 * CRD-7M2 : A variation of the CRD-7M, this configuration retains the XL gyro, jump jets, armor, Artemis-enhanced MML-7s, and anti-missile system of the original. The Streak SRM-4s and light PPCs are replaced by arm mounted Large Lasers. The right arm also carries a single machine gun. The left torso carries three tons of MML ammo protected by CASE II, while the right torso carries a ton of MML ammo, a ton of AMS ammo, and a half ton of machine gun ammunition; All are protected by CASE II. Two additional double heat sinks take the total up to twelve. BV (2.0) = 1,434


 * CRD-7W : The Crusader 7W introduced in 3071 was armed with two Krupp MML-9s and two MML-5s, which were capable of firing both LRM and SRM ammunition and were all linked to an Artemis IV FCS that increased their accuracy. These were backed up by two Diverse Optics ER medium lasers for close combat. In order to carry such a powerful payload, the 'Mech carried an XL engine and an XL Gyro to save as much weight as possible. The 7W also used twelve tons of light Ferro-Fibrous armor with CASE for protection. BV (2.0) = 1,221


 * CRD-8L : This Capellan Crusader variant, unveiled in 3083, carries two plasma rifles, ER medium lasers, and MML-7 launchers. The top speed of the 'Mech has been increased to 86 km/h by using an XL engine, and Endo Steel reduces weight. Eleven and a half tons of armor and CASE systems were used for protection. BV (2.0) = 1,701


 * CRD-8S : Created in 3066 with the mindset of "bigger is better", the 8S Crusader was built around an Endo Steel chassis and powered by an XL engine. The 'Mech carried two LRM-10 launchers and two medium lasers but was also armed with the new heavy Gauss Rifle, giving it great deal of close to medium-range firepower. BV (1.0) = 1,711; BV (2.0) = 1,698


 * CRD-8R : Developed after the Jihad, this variant returns to the fire support role. It carries an LRM-15 with Artemis IV FCS, a machine gun, and an ER medium laser in each arm. The traditional SRM launchers in the legs are replaced by Streak SRM-6 launchers. The right torso carries a ton of machine gun ammo and two tons of LRM ammo in a CASE II protected bay. The left torso carries a ton of LRM ammo and a ton of Streak ammo in another CASE II bay. The -8R keeps the top speed of 64 km/h and is protected by twelve tons of light Ferro-Fibrous armor. To make room for this equipment, the Crusader uses an XL engine and XL Gyro. BV (2.0) = 1,600


 * CRD-9BR : Derived from the Crusader Crael, this model carries an LRM-10 and Claws on each arm. The left and right torso have a single medium pulse laser, while the hips carry a pair of standard medium lasers. To reach a top speed of 86 km/h, the 'Mech carries an XXL engine and an XL Gyro. Thirteen double heat sinks are carried, but excess heat is turned to the 'Mech's advantage by using Triple Strength Myomer to improve ground speed and physical damage. The focus on close combat is clear since the 'Mech only has a single ton of LRM ammo in a CASE II protected bay. This is enough to provide cover fire as it closes in to short-range. BV (2.0) = 1,615


 * CRD-9R : An experiment in speed, this Crusader carries a 325-rated XXL engine to reach a top speed of 86 km/h. An XL Gyro is also fitted, as are twelve double heat sinks. The armament consists of an LRM-15, a light PPC, and a machine gun in each arm. The hip-mounted missile launchers are standard SRM-6s. A ton of SRM ammo, a ton of machine gun ammo, and two tons of LRM ammo are stored in the right torso, protected by CASE II. Twelve tons of standard armor provide protection. BV (2.0) = 1,612


 * CRD-10S : TharHes Industries created this version that mates all Clan-spec equipment with classic Crusader design. An Endo Steel skeleton and an XL engine are fitted. This gives a top speed of 86 km/h. Each arm carries an LRM-15 with an Artemis IV FCS, supplanted by a heavy machine gun and an ER medium pulse laser. Each hip mounts a Streak SRM-6. The side torsos each carry two tons of LRM ammo and a ton of Streak ammo, protected by integral CASE. The right torso also carries a ton of heavy machine gun ammunition. Fourteen double heat sinks dissipate the heat. BV (2.0) = 2,264

Custom Variants

 * CDR-3R Crael : Used by "Crusading Crael", the reigning champion of the DeathRain Arena in Port Krin on Antallos in 3057, this heavily modified Crusader had huge cosmetic spikes protruding from its chest and shoulders. These spikes served to conceal missile launchers, falling off as soon as the shoulder-mounted SRM 6s were fired for the first time. Its infighter capabilities were maximized by installing Claws on each arm. BV (2.0) = 1,204

Apocryphal Variants
From MechWarrior Online:
 * CRD-CR Crael : With the game engine for MechWarrior Online lacking support for leg-mounted weaponry and claws, Piranha Games Hero 'Mech version of the Crael instead moves the leg SRM-6 to the torsos and mounts a total of five machine guns in each arm to replicate its close-combat abilities.
