Background:

The SRLS-70 "Par'osh" ("Flea") is a multiple launch rocket system based on the RT-401 tank chassis and meant for use by airmobile and airborne troops. The Par'osh is an extremely mobile vehicle, both tactically and strategically. The light weight and small dimensions allow carrying 2 vehicles in a single medium transport aircraft (such as the C-130). This combined with its compact yet powerful 40 tube 70mm rocket launcher allow it to give airborne, airmobile and other troops rocket artillery support even in the most unreachable areas.
.
General Design:

As mentioned the SRLS-70 is based on the RT-401 chassis. It is a small vehicle with a crew of 3. The engine and transmission are mounted to the front and right of the tank, with the driver to their left. Behind him are the commander and weapons operator.

To the rear of the vehicle is a 180 degrees rotating launcher for 70mm rockets.

Armament:

Meant to bring rocket artillery support to airborne troops, the SRLS-70 is armed with a 40 tube launcher for the HLLCRS. The High Lethality Low Cost Rocket System is a Nachmerian of the Hydra 70 family. With an effective range of up to 12,000 meters, various warheads and fuze types are available.

Specifications:
Range: 8-12km
Diameter:70mm without fins
Length: 2m
Weight: 9-14.5kg depending on warhead.
Warhead: see below.
Guidance: Inertial or inertial+Laser Designation
CEP(Circular Error Probable): 50m(0.1m for laser designated rockets)


Common fusing options include airburst, point-detonation, and proximity.

For use with the SRLS-70, warhead types include White Phosphorous, High Explosive(2.2kg) , High-Explosive Fragmentation, High Explosive Anti-Tank(140mm penetration), Anti-Personnel Flechette (2,000 flechettes), Anti-Perssonel Thermo-baric, Illumination(both IR and visible), and smoke.

The Par'osh is equipped with a fire control system connected to the BASTION battle management system(or any other according to the user), and uses GPS coordinates and weather data to automatically calculate trajectories for free fall rockets. Using this system, the 70mm rockets have a circular error probable of 50 meters.

Other than free fall rockets, the H70PG line of rockets is guided in the terminal stage by laser designation. The three models include H70PG-01, H70PG-02 and H7-PG-03. 01 is equipped with the HEAT warhead, 02 with the airburst warhead, and 03 with the thermos-baric warhead. These rockets maneuver using their fins and exhaust, and have a circular error probable of 0.1 meters.


The system is capable of firing the rockets at a rate of 2 per second, with the capacity to fire one by one or in bursts of 10 available. When the 40 rockets are exhausted the launcher must be reloaded manually, but this is very easily done as the average rocket weighs less than 12 kilograms.

For self-defense purposes 7.62mm machinegun in a pintle mount near the commander's hatch allows for engagement of infantry at close ranges. The mount is simple and allows for a 230 degree fire arc as well as high elevation for AA fire.


Observation:

The commander has 230° field of view using 5 periscopes. At night the main episcope is replaced with a thermal viewer which can pivot left and right for a 120° field of view.

The driver has either three observation periscopes or two periscopes on both sides and a Driver’s Thermal Viewer. The periscopes provide 120°field of view.


Protection:

Due to the very tight weight limitations required for airborne transport, the Par'osh is protected only against small kinetic threats by its passive protection.

As mentioned the basic protection suit of the vehicle is aluminum armor. This armor is mostly non-perforated single plates, but some parts have spaced aluminum plates, for grater protection. Generally the Zariz passive armor is considered to counter KE threats up to 14.5mm in the frontal arc and around the turret, and 7.62mm on the hull sides and rear.

Crew and vehicle survivability:

The Par'osh has a Kevlar lining in the crew compartments to minimize spalling. The front mounted engine layout of the platform also adds a degree of crew survivability.

A fire suppression system is installed in the fighting compartment and engine compartment. The system has 3 visual and thermal fire detectors and 3 BCF canisters. The canisters are located in the commanders position (1), driver compartment (1) and engine compartment (1). The entire system is controlled from the weapons operator compartment, with the engine canister also being operated from the driver’s compartment. Diesel fuel for the engine is stored in 3 tanks in the front and back of the vehicle, with cutoff valves allowing the use of each tank separately.


Mobility:

The Par'osh is powered by a 6.7 liter commercially available engine providing 300 horsepower at max RPM. This diesel engine is coupled to an automatic gearbox with 3 forward gears and one reverse gear.

The suspension is a torsion bar design with 5 road wheel pairs per side. The track is slack and has no return rollers. Each track section is held to the next with a pin, and the pins are designed to break before the sections, as their replacement is far easier.

Communications and Networking:

The SLRS-70 has a standard Schwerpunkt combined internal/external communications system. The system comprises of a main control panel and 3 personal control panels, as well as 3 headsets integrated into the ballistic helmets of the crew.

The main control panel is located in the commander’s compartment and allows him to select listening and broadcasting frequencies for himself and the crew, select which crewmembers can hear him and be heard by him, and which crewmembers can listen and broadcast to external radio. The individual control panels allow each crew member to switch select listening channels and select which crew members he can hear. The commander’s panel also allows for remotely changing the frequency in the receivers and transmitters. The PTT integrated into the helmet has three modes- internal, external, and quiet. The system has a separate tank commander to driver channel using the most protected battery for power to ensure commander-driver communications. The system also has a wireless ability, which switches on automatically when a helmet is disconnected. This prevents crew members from accidently disconnecting and allows for quick dismount.

The SLRS can accommodate 2 transmitter-receivers and 1 receiver. The antenna bases are integral and allow lowering the antennas forwards and backwards from inside the tank. The SLRS-70 is equipped with a tank/infantry telephone located at the rear of the vehicle and connected to the commander’s internal communications, as well as external communications to allow infantry to use the tank to communicate.


Networking for the Par'osh is provided by the BASTION system. BASTION is a battlefield management system for units ranging in size from platoons to brigades.

BASTION mostly relies on the existing sensors a platform already has. This includes laser range finders, RADARs, observation systems, fire control components, meteorological sensors, and other sensors. It also uses GPS (either installed with BASTION or existing). Combining information from these sensors allows the system to display and network accurate real-time information not only of friendly forces, but also of hostile forces, terrain conditions and more.

BASTION can rely on several communication mediums. It can use standard military radio networks, military cellular networks, or satellite communications. It can also combine all three. According to the type of medium used, range varies from a few kilometers to thousands of kilometers.

Networking is done by an IP protocol. Each unit sends and receives information to and from all units within reception range and operating on the correct frequencies. This information is than sorted by the system, to prevent flooding the user with un-needed information. This sorting is done by both the sender and recipient, meaning he user can choose who will see his sent data and who’s sent data he receives.

The information gathered by the BASTION main processor is displayed on one or more LCD displays in the vehicle. The LCD screens are mil-spec and have control buttons on the sides. The system has 4 windows used for work before, during, and after operations.

*Battle Planning and orders: Allows for creating, sharing and viewing complete operational plans, with attached maps, orders, and ORBATS. It allows for viewing the battle image over code-maps, satellite images, or 3D terrain visualizations. The user can also calculate point-to-point distances, lines-of-sight, and radio reception areas.

*Battle Management: This is the main window, which is used during operations. It allows for viewing the battle image over code-maps, satellite images, or 3D terrain visualizations. The user can see the location of friendly forces and known hostile forces. The user can also update known enemy forces. This is done by taking a range reading to the enemy, and then adding further information manually. Artillery can be laid using a special artillery tab, which sends the artillery request to a predefined user. The user can also calculate point-to-point distances, and lines-of-sight. Information added here by the user is automatically shared with other units.

*Information Sharing: This window is used to send specific data that is not automatically sent by the system. This includes text massages, images and videos, and logistic reports. Videos and still images are captured by the AFVs existing systems. Text massaging allows free texting as well as predefined default massages. This system allows upper echelons to view the battle from the perspective of a specific tank, and also reduces the use of radio by lower tactical levels.

*Internal Status: The window is used for updating the status of the specific unit carrying the BASTION. It allows updating ammunition and fuel shortages, mechanical problems, casualties, etc. This information is only sent when the user chooses to (manually or in predefined intervals).


Crew Amenities:

The SRLS is equipped to support its crew in long term operations during fighting and when buttoned. A specially designed sun and rain plastic canopy can be raised above the hatches to ease waiting periods in harsh weather. A 30 liter NBC protected water tank located in the rear hull and supplies hot or cold water thorough a tap. Rations are kept in water tight compartments in the fighting compartment itself. corridor. 3 days worth of rations can be carried in this way. The tank has a special storage compartment holding an electric cooking boiler and frying pan.

All questions and puchases should be made in the main Schwerpunkt storefront.
