Developed for use by the Royal regiments of the SLDF by Earthwerks Ltd. of Terra, in the Terran Hegemony, the Mastiff BattleMech has a long history with the Star League. Designed to operate in any environment, and fill many different roles, the Mastiff was built using advanced structural materials and cutting edge weapons technology. At the time of its production it was a well respected 'Mech that became an oft requested BattleMech for many regiments.  One of the most interesting facts surrounding the Mastiff, was that it was the specific target of an almost perfectly executed industrial espionage operation by Kallon Industries.

Suffering from a lack of funding, Kallon had gotten word that Earthwerks was developing a multi-role 'Mech for the SLDF. Lacking a design that they felt would garner a contract from the SLDF Quartermaster's Command, Kallon Industries set out to acquire the design specifications of the Earthwerks 'Mech design.

On 31 May, 2637, just as Earthwerks was about to begin physical construction on the prototype Mastiff , Kallon Industries bank-rolled industrial spies penetrated the Earthwerks technical mainframe and downloaded the design schematics and component list for the Mastiff BattleMech. Utilizing the relatively new hyper pulse generators, the spies sent the information packet to the Kallon Industries facility on Thermopolis, where production of the Mastiff was begun immediately. This new 'Mech was marketed to the SLDF Quartermaster's Command at almost the same time as the Mastiff . There were a few glaring discrepancies however, between the two BattleMechs. Most notably was the price. The Kallon Industries 'Mech was nearly 500 thousand SL-bills less expensive than the Earthwerks' Mastiff .  It was soon apparent why.

Attempting to be as unobtrusive as possible, the Kallon hackers on site at the Earthwerks facility knew that speed was a key factor in performing their mission without notice.  As such, they were unaware that they stole a completed prototype file that was developed for low-cost, high-efficiency, utilizing "simple" technologies. The production model of the Mastiff was developed using advanced weapon systems, and cutting-edge structural technologies. The Kallon Industries designated Wolverine WVR-6R was the wrong 'Mech.

Embarrassed and financially hurting, Kallon Industries offered the first production run of their stolen design to the SLDF at a significantly discounted price. Later combat actions in the Martial Olympiads proved the value of the Wolverine, and the BattleMech was purchased on a grand scale and distributed among the regular army regiments of the SLDF. The more advanced Mastiff 'Mechs were distributed among the Royal regiments.

Most notable of the Mastiff's design features is the endo-steel internal structure. Considered state-of-the-art at the time of it's first construction, the chassis weighs in at only 3.0 tons, allowing the 'Mech to carry a significant weapons payload.

The Core Tek 275 fusion engine, produced on Terra by Blankenburg Technologies provides the BattleMech with a respectable land speed of 54.0 km/h, and a running speed of 86.4 km/h. Combined with the torso mounted Rawlings 55 jump jets, the Mastiff is quite mobile for a 'Mech of it's size.

Wrapped in 10.5 tons of Krupp 155 armor, the Mastiff carries 90% of the maximum armor load for a BattleMech of it's weight class. What makes the 'Mech so durable on the field however is not the armor coverage, though that helps, but the Cellular Ammunition Storage Equipment. The CASE provides a level of protection to the 'Mech and pilot that most machines of the age do not share.

To keep the Mastiff in close contact with the rest of its regiment, Earthwerks equipped the BattleMech with the Exeter Longscan 200 communications suite. Also from Krupp Armaments is the reliable and trusted Garret T12A target and tracking system, known for it's accuracy.

Providing the Mastiff with it's firepower is an Imperator Ultra AC/5 autocannon. Carrying two tons of CASE protected ammunition allows the BattleMech to perform for long periods of time without resupply. For close range combat the Mastiff carries a Blankenburg Technologies medium laser and two Holly 2 Streak SRM 2 missile launchers, carrying a ton of CASE protected ammunition. The Streak technology allows for maximum damage potential while at the same time, offering 100% efficient ammunition conservation.

Battle History
First seeing combat in the Martial Olympiad of 2640, the superior performance of the Mastiff immediately ingratiated the BattleMech with the command structure of the SLDF. Over the course of it's history with the SLDF the 'Mech was involved in almost every combat action that the Royal regiments fought, up to and including the Terran Hegemony Campaign through to the Exodus of Kerensky.

Deployed among all the Royal regiments of the SLDF, the Mastiff was regarded as an excellent medium BattleMech, and one of the most commonly requested 'Mechs among commanders of medium battalions. Some Mastiffs went with General Kerensky during the Exodus. No known Mastiffs have been found in any Brian Caches since the return of the Clans.

Known Variants
The WVR-6R Wolverine is the only known variant of the Mastiff BattleMech. Ironically more successful than the Mastiff due to it's "simple" technology components, the Wolverine has lasted through the ages. Since the fall of the Star League, and the Succession Wars, the durable and reliable Wolverine has spawned several variants, and it has become a favored BattleMech of nearly all the militaries of the Inner Sphere. The irony of the success of a stolen design over that of its predecessor is not a subtle one.

Notable 'Mechs and Mechwarriors
Sgt. Harald Brocken: The most decorated of all Mechwarriors who piloted a Mastiff in the first seven Martial Olympiads, Sgt. Brocken was a quiet man of German decent. He fought hard for the SLDF, and was a trusted lance commander. He possessed an excellent tactical mind and served the SLDF with distinction. Incredibly, for an old soldier, he died at the age of 117 of natural causes.

Obviously better than the Wolverine (but with the use of advanced tech it is easy).
I really like your fluff and the development of the Wolverine.

Good job.

Hrm, the predecessor to the Wolverine? Decent 'Mech all around, reminds me of a heavier Sentinel.

Great story and write up, especially of the "Wolverine's" evolution.
