M7101 Mammoth (FRAUT)

The M7101 Mamoth is a FRAUT, designed by Federal Defence. The vehicle was designed beginning in 2012, and entered service the the Federal Republic Land Force Command in 2016. Production of the M7101 entered full rate in 2016 and so far 37 vehicles have been produced, with a total of 1,500 planned initially. The vehicle has not seen any conflicts yet. The M7101 is the highest technology armored vehicle produced in the FRAUT.

History
The M90 Centaurus designed in 2008 was an effective Main Battle Tank, but was not capable of extremely long range engagements. Furthermore, the M90 Centaurus also had limited protection in urban environments. The 1st Heavy Armored Division was only equipped with the older M79 Main Battle Tanks, as a new Heavy Tank had not been developed since the 1960s. In 2011, The Command Administration Group Center issued a development bid proposal for a new, high technology Heavy Tank. Federal Defence was selected in October 2011, and development began. In 2015 prototype 0 of the XMH 100 Heavy Tank was delivered to the Federal Republic Land Force Command for testing. The vehicle did not successfully complete initial trials. Tests found the new, 145mm gun was suffering because the electronic calibration system did not function as intended. To remedy this, a Muzzle Reference System was added to enable a laser bore-sight, which provides a more accurate baseline for electronic calibration. In urban warfare testing, the M450 HB Commander's Weapon left the vehicle too vulnerable. So, a new prototype Low Profile Armored Remote Weapons Station was added. This RWS subsequently completed independent trials and was designated the M954 RWS. The vehicle underwent further evaluations in the new prototype 1 variant, and successfully completed evaluations in June of 2015. The vehicle was then sent to the Dark Horse Dragoons for operational testing. The Dragoons found the vehicle to be highly effective as a heavy tank, and with this recommendation the vehicle was approved for full rate production in January of 2016.

Design
While the M7101 is classified as a heavy tank due to size and weight, it has no similarities to a historical heavy tank. Instead, it uses the profile and technological basis of a Main Battle Tank, with a much larger weapon and more armor. The M7101 has several differences between the M90 and itself.

The M7101 is fully electronic and computerized, allowing for greater control of all weapon systems and other supporting systems.

Gun
The M870 Gun is a 145mm rifled gun specifically designed for use on the M7101. The large caliber weapon uses a triple cold forged carbon nano-tube reinforced barrel allowing for long barrel life and for sustained firing. The weapon is electronically elevated. It features a laser bore-sighting system with a Muzzle Reference system allowing for extremely accurate weapon zeroing. The M870 Gun is capable of hitting targets with 0.1 mil dispersion at 22,000m. The M870 Gun is mated to the new NG-EFS (Next Generation Electronic Fire Control System), allowing for automatic lead, windage, and range calcuation. The NG-EFC is fully battlefield networked enabling information sharing to all M90 and M7101 Tanks during operations. The M870 Gun can fire a variety of ammunition:
 * SS145870 Armor Piercing, Discarding Sabot, Fin Stabilized Nano-tube reinforced Composite Core Super SABOT (APDSFS/SS)
 * H145A170 High Explosive Reactive Core Multi Trigger Anti Tank, Fin Stabilized (HEAT/RC)
 * H145899 High Explosive, Dual Purpose Heavy Attack, Fin Stabilized (HEDP/HA)

Protection
The M7101 uses a classified, composite armor package that is said to provide unrivaled protection. The vehicle combines traditional composite armor with a classified, fully electronic active protection system which can defeat both SABOT type and HEAT type devices. The vehicle also had an advanced mine detection ground penetrating RADAR to provide early warning against IEDs or land mines.

Mobility
The M7101 is equipped with the FD 102162 W16 Twin Turbo Diesel engine. The W-16 design is paired with four turbo chargers, one for every 4 cylinders. All four turbochargers are mated to a single, low profile inter cooler system. The exhaust is cooled with an active system to lower the heat signature of the vehicle. The engine is rated at 1,800hp at 1000RPM. The engine is fully electronically controlled and features drive, brake, and steer by wire. The powerpack is modular, allowing replacement of the engine or transmission inn under 3 hours due to quick release connections and very few wires. It is mated to a 15 speed transmission electronically, placing much less load on the semi-automatic sequential transmission.

Electronics
The M7101 uses a highly advanced electronic control system. The vehicle eliminates heavy shielded cabling and instead uses lightweight, sold state fiber optic channels for all data transfer. This allows the weight to remain the same as a main battle tank, while having more advanced systems and a much larger overall profile. The vehicle has classified systems for all aspects of vehicle operation. Engine management, fire control, active protection, and crew systems are all controlled by their own systems. All systems are considered triple redundant and operate on separate power delivery networks. All systems are also heavy shielded to prevent interference from jamming or electro-magnetic pulse attacks. This allows the vehicle to continue to communicate in the event of these attacks.

M7101 "Mammoth"
The M7101 Mammoth is the first iteration and designation of the vehicle after the completion of testing. the M7101 was given this designation and title of Mammoth in July 2016. The vehicle is aptly named the mammoth as it is currently the largest armored vehicle in the Land Force Command arsenal. The vehicle will initially be fielded to all Armored Regiments in the 1st Heavy Armored Division. However, the Land Force Command has stated that if the vehicle performs exceptionally in service, it may be transferred to additional regiments in the 1st and 2nd Mechanized Division to completely replace the M90 Centaurus. Currently the Land Force Command has stated that the budget will not allow for such an endeavor unless mass production is achieved if the vehicle will be fielded to four of the five divisions. The M7101 is painted with the Adaptive Woodland Camouflage pattern for woodland environments, although some initial vehicles still bear the Federal Green color scheme when released from the production facility.
