Overveiw:
The G.I.F’s first domestically produced tank, the G1-Raksha was designed in conjunction by CAW and Dala. Work was started on the design of what would become the Raksha in 2034, after the senate approved a 600 million IFY budget for the design and production of a prototype and subsequently a production of a new mbt to replace the aging Leo 2a7E’s imported from the German federation. The requirements for the new tank were as follows: a 152mm smoothbore main gun, a weight under 68 tones and hard kill protection systems.
Survivability:
A new composite armor was developed for the Raksha by Dala in the Nakai armor labs. Nakai armor was tested against a 120m L44 firing M829A2 APFSDS from three ranges, 1,000m, 500m and 10m. The Nakai armor survived a M829A2 from 1,000m and 500m, however the M829A2 successfully penetrated at 10m. The Raksha is still vulnerable to attacks to the top of the turret. To combat this, an additional 400 million IFY to develop a more effective DERA system to be integrated into the tank. The system developed by Dala, can track and destroy up to 4 targets simultaneously.for additional protection, ERA can be added to the hull to improve survivability, however no additional ERA can be added to the turret as it would block the DERA system. The base of the hull is constructed out of depleted uranium composite. All this allows the Effective Maximum frontal armor to be comparable to 2,000mm RHA vs. KE, 2,800mm RHA vs HEAT and a frontal minimum of 980mm RHA vs KE, 1,800mm RHA vs HEAT..
Engine:
The Raksha 1 use the DCG MB 320 SC-501 Liquid cooled v12 twin turbo diesel engine. The engine operates at 2,000 psi and produces 1,979 horsepower and 1,603kW at 3,100 RPM. Located in the rear of the tank, the engine allows the Raksha to move at speeds of up to 75km/h. The Raksha has a fuel capacity of 1,300 litres and an operational range of 530 km.
Main Gun:
The Raksha uses the CAW produced C835 Mark 2 152mm smoothbore cannon. The massive cannon uses a innovative autoloading system that allows for shell types to be changed after every shot and allows the C835 fired at 9.52 rounds per minute. The C835 has access to a wide range of shells, however, four shells are most often used. The shells are as follows: 1. C812 Ajagar: The C812 Ajagar MPAT. The C812 MPAT shell is the base for many different warheads including the W31 OTES (Obscured target engagement system) tandem warhead; the shell uses laser guidance from the O.C.CAM (Over Cover Camera) and 8 fins that allow the C812-W31 shell to make precision strikes on targets behind cover and out of a direct line of sight. The W31 has a penetration of around 900mm. W31 OTES is not widely used however as it is an expensive shell. W7 CAIM; the W7 CAIM or Cluster Anti Infantry shell is a anti personnel shell that uses the airburst designator system incorporated into to Raksha to detonate at a set position behind cover and deploys cluster munitions to eliminate large groups of dug in enemy infantry. W4E2 HE shell. The W4E2 HE shell is used to engage fortifications, light armored vehicles and other soft targets. 2. W12E4 APFSDS shell. The W12E4 APFSDS is a high velocity shell that uses a 5 cm wide 150 cm long depleted uranium long rod penetrator. The muzzle velocity of the W12EF is high, around 1,600m/s that the shell is capable of penetrating 1.4 meters of armor even at extreme ranges. A benefit for using depleted uranium LRPs over tungsten LRPs is that depleted uranium does not deform on impact as tungsten does, leading to a superior LRP. The large gun has one downside however. The turret larger than most other tanks, and a large portion of the turret is taken up by shells stored in blowout compartments in the rear of the turret. This is a drawback because to move shells up from the rear of the turret, a blast door has to be opened and new shells slid forward.
Secondary weaponry:
In addition to the C835 Mark 2, the Raksha utilizes the AGl-32 Lau Dhaara RWS system. The LD (as operators have shortened it) Fires a 40x50mm airburst grenade to great effect against infantry and very lightly armored vehicles. With a fire rate of 253 rounds per minute and a effective range of out to around 2,200 m however, most engagements with the RWS occur at a range of 1,500 meters. The LD RWS uses a belt feed system and a computerized view/range finder to provide pinpoint accuracy and detonate rounds with precision. In addition to the LD, the Raksha also has a standard 12.7 coaxial for additional anti infantry capability.
FCS&Optics
The Raksha uses the Dala Sabhee Sait FCS system. The Raksha uses the LRF-2BT laser rangefinder.. Capable of acquiring and tracking at up to a range of 10km, however the maximum range targets are acquired at in combat is around 5km. The Sateek Hava CWC-1G Cross Wind compensator allows for accurate fire at extreme ranges. Targets are acquired by using the CAW developed TGS-12 Hok Takatakee which uses a standard view camera and a thermographic camera. This system is used as the base system for the primary gunner's sight and the Commander's periscope. The camera is rated up to at a range up to 10km kilometer and posses 60X zoom with high fidelity. Due to rough terrain in the usual region of operation, the Raksha is linked to a advanced gun stabilization system and a trigger-delay system. This system is used to optimize accuracy even while moving at rapid speeds over extremely rough terrain. In the event of the gunner firing at the moment of the tank encountering a irregularity in the terrain, the oscillation of the gun barrel will cause a temporary misalignment between the laser emitter on the barrel and the sensor on the base. In this event, the FCS will not activate until the beams are re-aligned allowing for a greatly improved chance of hitting the target.
An innovative system of the Raksha is the ability for the commander to take control of the main gun and turret from the gunner in the unlikely event the gunner is incapacitated. Additionally in an emergency the tank can be operated by only two or even one crew member. This ability is due to the ability for the feeds from the PGC (Primary gun camera) or PCC (Primary comander camera) to be relayed to any of the crews positions. This is far from ideal however as operating the tank in such a way overloads crew members and is only ever used in a critical.
