Background information
The M7A2-S SEP Gray Fox is the export version of Artaecus' domestically produced M7A2 SEP. The M7A2-S SEP (Survival Enhancement Package) is the export variant of the latest iteration of the M7A2 and features no deviations from the original model except for the change in gun calibre (120mm) to fit the export market. The vehicle features several unique features such as a rear door and compartment for carrying troops into battle, extra ammunition storage or even a mobile hospital. It also features a brand new Gas Turbine Engine which improves performance and reduces fuel consumption by almost half from previous version, allowing for a greater range without the aid of an external fuel tank. It doesn't stop there, all these new changes are just scratching the surface of the A2 model.
Design
The M7A2-S SEP Gray Fox was designed from the ground up to be cost effective and easy to maintain and repair without sacrificing any of the performance or protection of the vehicle itself.
The Turret
The A2 turret had been significantly redesigned from the previous A1 version. The turret is now more compact with the intention of fitting modular armor all around the structure itself, allowing for quick repairs and upgrades without having to replace everything entirely like conventional cast turrets. The modular armor would fit into specific slabs and takes no longer than 15 minutes to replace an armour module. The unique design of the individual modules also allows for the implementation of several different packages and options such as the Firewall APS, Optical-dazzlers and so forth. Fitting these systems are as easy as just connecting them onto the hardpoints of the modular armour and in itself is meant to be compatible with almost all other systems on the market (Such as the Shield APS, for example).
The turret was specifically designed to house calibres up to 140mm's, with the turret also being designed around the use of an autoloading system. A single 14.5mm machine gun serves as the coaxial machinegun, which is placed directly to the left of the main gun. From the demands of the Artaecusian tank commanders, a single 60mm mortar comes standard with the vehicle itself. Unlike several other designs, the A2's turret is not hydraulically powered due to concerns of the flammable liquids it utilizes. Instead, it is electronically powered either by the engine or an independent generator when the engine is off. The roof has also been redesigned with countering the ATGM threat in mind, and as a result the gunner's hatch has been removed. In its place is the commander's indepent sight, with 360 degrees field of view and supporting 3rd generation night vision technology. Connect to it is another 14.5mm machine gun. On the rear of the turret lies twin turreted grenade launchers and several sensors, these exterior and internal sensors essentially gather environmental data in order to provide more accurate fire control solutions. On either side of the turret lies the MEFP Hard-kill launchers of the Firewall Active Protection System, they provide a 360 degree field of protection from ATGM's and RPG's should the initial Soft-kill system fail.
Crew comfort was placed above all besides protection, so the interior had been specifically designed to give the crew enough space for each man to reduce both fatigue and the claustrophobic feeling so they remain combat effective for long hours.
The Hull
The hull had also been tweaked, now the side armour is also completely modular in the form of small replacable boxes to speed up repair. A more refined version of the Active Hydropneumatic suspension had also been implemented. The frontal armour has mostly been left untouched, the only changes being the new add-on armour to both the top of the hull and the implementation of a thicker belly plate to increase protection. The rear compartment now features several different packages to suit different situational needs. To name a few, a hospital module could be implemented complete with life support systems and 4 stretchers. Another is a crew resting area complete with a toilet, a tea making facility and other features that would reduce fatigue and stress on the battlefield. As standard, the M7A2-S SEP Gray Fox will come in its personnel carrier configuration. This allows the vehicle to carry up to 6 fully kitted soldiers into battle without having to remove extra ammunition as in the previous version (Most ammunition is stored in the turret).
Propulsion/Mobility
Tactical
The M7A2-S SEP Gray Fox features a domestically produced Octanus H-333E Multi-fuel Gas Turbine Engine capable of 1,500 shaft horsepower (1,120 kW) at 3,000 rpm and 3,950 lb⋅ft (5,360 N⋅m) at 1,000 rpm and a modified six-speed (four forward, two reverse) Allison X-1100-3C Hydro-Kinetic automatic transmission. The engine has been governed to extend its operational lifespan, but is still capable of speeds up to 63.02 km/h (39 mph) cross country and 72 km/h (45 mph) on paved and smooth roads. This makes the tank ideal for lightning quick ambushes and spearheading advances at incredible speeds. The tank was built around this engine and it is multifuel–capable, including diesel, kerosene, any grade of motor gasoline, and jet fuel (such as JP-4 or JP-8). The new engine is lighter and smaller (43% fewer parts) with rapid acceleration, quieter running, and no visible exhaust. Replacement has never been easier as well, as the new design allows for a quick near drop-in replacement.
The Octanus H-333E Multi-fuel Gas Turbine Engine has proven quite reliable in practice and combat, with the E model fixing the alarming fuel consumption rate of 3.15 L (0.83 US gallons) per kilometre. The turbine is very quiet when compared to diesel engines of similar power output and produces a significantly different sound from a contemporary diesel tank engine, similar to a turbocharged hairdryer which significantly reduces the audible distance of the sound.
The UVTT tracks (double-pin center guide with rubber pad inserts) had been specifically designed to deal the rough terrain of Artaecus' landscape, the rubber padding incorporated into the tracks also allows it to travel on roads without damaging it too much. The gas capacity is 1,400 litres (308 imperial gallons; 370 US gallons).
The engine is placed near towards the front of the tank to clear up the rear section for the crew. Though this may raise some concerns about engine fires, the front side of both the turret and hull are the most heavily armoured sections of the entire vehicle. The fuel tank is self-sealing and has an automated fire extinguisher in case of an emergency. It is also important to note that the engine being used is not nearly large enough to compromise the hull armour composition and lead to weaknesses, the tank was designed around this Gas Turbine after all.
Strategic
The M7A2-S SEP is fully capable of transport on land, sea, and railway if needed. Transportation by airlift or railway may require you to remove the modular armor and other attachments that may make the overall size of the vehicle too large but with most cases, you are not required to disassemble parts of the vehicle.
M7A2-S SEP is also transportable by truck, namely the M1070 Heavy Equipment Transporter (HET), but given a large enough trailer with sufficient power should be compatible with any truck.
Armament
AIM X-01 L/52 120mm smoothbore gun
The main armament of the M7A2-S SEP Gray Fox is the AIM X-01 L/52 120mm smoothbore gun. It is optimized for autoloader use, featuring 36 rounds in the magazine with the capability of firing 12 rounds per minute. The AIM X-01 was tuned to mainly fire Chaos rounds but does accept any type of 120mm ammunition as long as it fits the dimensions. The AIM X-01 is also capable of firing a domestically produced Tandem Warhead ATGM from the barrel, capable of two different modes of tracking by laser or electro-optically from its onboard camera. Most of the characteristics and technology is still classified, so only users of the M7A2-S SEP are allowed sale of the missile. Depending on the ammunition, the weapon is capable of firing up to 8 kilometres with precision and this range extends even further through the use of ATGM or any type of rocket motor assisted munitions.
Secondary
A 14.5mm AARM K-98 machine gun is mounted on the Commanders Independent Sight (CIS) effectively allowing the commander to deal with infantry threats from within the turret. The weapon's larger calibre makes it a multipurpose weapon, the two most notable roles for the weapon being anti-infantry and anti-material.
A 14.5mm AARM K-98 machine gun in a coaxial mount to the right of the main gun. The coaxial MG is aimed and fired with the same computerized firing control system used for the main gun. It is interchangeable with larger or smaller calibres to suit your requirements (Completely compatible with the Feurig's WA 20 mm cannon).
A 60mm mortar is fitted to suppress and eliminate with entrenched infantry or firing smoke rounds for support. It is both reloaded and fired from inside.
Aiming
The Ironsight Fire Control System offers unparalleled performance in battlefield conditions. Featuring long-range, day and night, on-the-move high first round hit probability against stationary and moving targets. Reliable, cost-effective, and easily configurable to fit the users needs, the system turns the M7A2-S SEP into an efficient, high-performance killing machine with improved hunter-killer capabilities. It uses user and system-supplied data from a variety of sources to compute, display, and incorporate the three components of a ballistic solution—lead angle, ammunition type, and range to the target—to accurately fire the main gun. These three components are determined using a laser rangefinder, crosswind sensor, a pendulum static cant sensor, data concerning performance and flight characteristics of each specific type of round, tank-specific boresight alignment data, ammunition temperature, air temperature, barometric pressure, a muzzle reference system (MRS) that determines and compensates for barrel drop at the muzzle due to gravitational pull and barrel heating due to firing or sunlight, and target speed determined by tracking rate tachometers in the Gunner's or Commander's Controls Handles. All of these factors are computed into a ballistic solution and updated 45 times per second to ensure a hit percentage greater than 98 percent at nominal ranges.
The M7A2-S SEP utilizes both thermal, night, and reflective mirror viewpoints to spot targets; targets are usually spotted immediately and targets are arranged from the most imminent threat to the lowest by the ballistic computer. The tank's main sights are within an armoured turret that is capable of 360 degree rotation to either side, within them containing a HD camera feed, thermal camera, 3rd generation night vision camera, and a rangefinder among other visual targeting components. There is a secondary gunner sight should the main one fail, but it is fixed to the turret's superstructure and cannot rotate. In the event of a catastrophic failure, either the commander or gunner can fire the main gun through an override system should a crew member die. The turret also has a handcrank system if the electricity is cut. In the event of a malfunction or damage to both the primary and secondary sight system, the main and coaxial weapons can be manually aimed using a telescopic scope boresighted to the main gun known as the Gunner's Auxiliary Sight (GAS)
