Operational range: 400 KM

Overview:

The S-1 tank was developed for the doctrine, to operate within the large armies of the nations of the PSUS, and to dominate the battlefield with superior firepower, armor, and tracking. However, tradeoffs had to made, and the S-1 is not meant to be a efficient vehicle in regards to logistics. With all this in mind, the creators of the S-1, the design departments of Vostokja and Solyhniya set out on their mission. After half a decade of research, and 1 billion dollars, a prototype of the S-1 tank finally came out.

Armour and Counter measures:

The S-1 has a three types of defense against KE and HEAT rounds. The first line, is external devices like ERA bricks. The design of the ERA bricks is special, involving 4 metal plates, as the round impacts, it sets of the metal plates, which push against, and thus weaken the HEAT round. Another device that is used, is a small little compartment, fitted with explosives. Once external sensors detect an incoming round, within milliseconds, the little container explodes, weakening the force of the incoming round. Around 10 of this compartments exist all around the tank. The second line of physical defense, is the Armour itself. The Armour is a multilayered composite consisting of Ceramic, Tungsten Carbide, Steel, Kevlar and titanium. The predominant materials are Ceramic and Tungsten Carbide. Tungsten Carbide was chosen for its high impact strength, and thus deemed ideal for dealing with Kinetic energy penetrators. Tungsten carbide has a strength of 550 Gpa, much stronger than titanium (used in some tanks) . Ceramic (especially the highly heat resistant titanium carbide) was also chosen for its high resistance to heat, as well as its hardness, thus able to defeat incoming HEAT rounds. Finally, the S-1 comes with a few other mechanisms to prevent a round from being fired at it and hitting. The S-1 is equipped with various smoke and chemical grenades, that can throw off thermal tracking, and laser guided tracking as well, with the ports for launching built into the turret of the tank.

What I have so far, of a tank I want to design exclusively for my alliance, PSUS (Pan Slavic Union State).

I wonder why a 48-tonne tank is heavy on logistics. I also wonder what you did to get that weight in the first place, since the tank sounds for all intents and purposes Western rather than Russian now.

Descriptions of tank armor contain the highest concentration of technobabble confirmed to exist outside of FT.

I assume the third line of defence is the bodies of your crew

ERA: Why 4 plates? Do elaborate, I am curious. Also, 10 compartments of smart era for the entire tank would mean losing a lot of protection after the first round (ERA cant really be reused or layered, see)

Armour: Yes ceramic is used for its hardness, but not heat resistance. HEAT rounds don't penetrate by heat, they penetrate by using explosives to punch copper into your armour. The harder the armour, the faster the copper jet is eroded, the less it peentrates. Nothing to do with heat.

Looks a bit on the light side. Armour stats in terms of RHAe? NSD is happy to help

I was wondering how I could calculate RHAe, since right now I have no idea.
Would be grateful to anyone who could tell me how.

Actually, it's a pretty good idea NOT to calc the RHAe. Even people like Sumer have made mistakes in such calculations, so I don't consider them (RHAe ratings) to be too valuable, with NS tanks.

After half a decade of research, and 1 billion dollars, a prototype of the S-1 tank finally came out.

Armour:

The S-1, in accordance with the military doctrine that it was designed for, was fitted with what the designers considered the best armor practically possible. It is in this quest, that engineers decided to use a new composite was needed, combining various elements. The S-1 has a three types of defense against KE and HEAT rounds. The first line, is external devices like ERA bricks. The design of the ERA bricks is special, involving 4 metal plates, as the round impacts, it sets of the metal plates, which push against, and thus weaken the HEAT round. Another device that is used, is a small little compartment, fitted with explosives. Once external sensors detect an incoming round, within milliseconds, the little container explodes, weakening the force of the incoming round. Around 10 of these compartments exist all around the tank. The second line of physical defense, is the armor itself. The armor is a multilayer composite consisting of Ceramic, Tungsten Carbide, Steel, Kevlar and titanium. The predominant materials are Ceramic and Tungsten Carbide. Tungsten Carbide was chosen for its high impact strength, and thus deemed ideal for dealing with Kinetic energy penetrators. Boron carbide is a strong metal in regards to impact strength, ranking 9.3 on the mohs scale, much stronger than titanium (used in some tanks) . Ceramic was also chosen for its hardness, thus able to defeat incoming HEAT rounds. The S-1 also makes use of sloped Armour, to deflect damage from an incoming round.

Counter measures:

While the S-1 uses a very strong composite armor, making it resistant to KE and HEAT rounds, the designers also included various countermeasures. The designers realized three likely measures for missiles and/or tank rounds that would be used against them:

• Thermal imaging
• Wire guided missiles
• Laser guided

Thus, for each one, scientists came up with solutions to throw off the incoming round(s):

• Thermal imaging can be distorted or thrown off by the use of 6 heat flares, 3 on each side, concealed in specially created internal ports, to prevent damage by external fire.
• To deflect laser guided ATGM rounds or other tank rounds, 4 aerosol grenades can be deployed within half a second, to distort the path of the laser, making tracking much more difficult for the enemy.

The designers also foresaw the need to provide measures to deal with air strikes. Thus engineers came up with two fairly cheap solutions to throw off aircraft that may strike the tanks. Every tank is equipped with two devices, the first device is a metal pyramid type device, that can mimic the radar signature of a tank, when the tank is not in motion. Crews may place this away from the tank, to confuse enemy air forces into firing missiles into empty positions. Another measure meant to deal with the thermal imaging aspects while the tank is parked, is a small, two thousand dollar electronic device, that can mimic the heat signature of a tank, to aircraft and vehicles patrolling the area. These two fairly inexpensive solutions make tracking the S-1 much harder.

Networking:

Owing to mistakes made by other Slavic nations, that placed little importance on computers or the modern battlefield, designers of the S-1 sought to correct this mistake, and make a truly modern tank. The S-1 is fitted with a highly advanced computer interface, each crew member has access to at least 1 computer screen, with the commander having 4, each displaying vital stats and other relevant information. The S-1 can be hooked up to BATTLENET, a system enabling communication between tanks, as well as the ability for one tank to track a target, while another tank fires at the target. Other measures are included, so as to ensure full battlefield integration.

Won't work.

Just use smoke grenades, they work equally well against all three of the guidance methods you mentioned.

Edited.

omg T55 pic

use less thus, it only makes you look smart when used in certain circumstances and makes the writeup kind of hard to follow

also, your smart ERA is in 10 compartments. so a hit would expose a tenth of your hull unprotected by smart ERA. a tenth is a lot, plenty enough to aim at for the second round to mess you up.

also, i lold at your decoys
metal pyramid has radar signature of pyramid
fake tank made of 2mm sheet metal has radar signature of a tank
i suppose you could get the sheet metal parts on the tank and have it quick assemble so 30 mins the crew can assemble a fake tank

whatever is making the heat signature would have to mimic thermal conductivity through the tank as well, which would be much much easier done if it was made as wide as a tank

Fail.

Rotating pyramid decoys are used IRL.

first of all it's an M84 :/

second of all don't talk about sounding smart you hypocrite

Wouldn't estusia need to complain about someone not sounding smart to be a hypocrite?

To decoy a thermal imager you'll need an actual full sized mockup. Put the heater in that and you're getting somewhere.

I decided to replace a Turboshaft engine with a Diesel one, since I read Diesel is cheaper, easier to maintain, and most of all has a reduced heat signature.
Does anyone else agree with this?

Diesel also uses less fuel.

And most importantly, diesel uses a lot less fuel. Which is the main weakness of the turboshaft engine.

Diesel is good and works fine.

Also, I noticed you use Wolfram-carbide. I thought that stuff provided less protection for simmilar weight?

Your MG's seem based of an unusual calibre. Is there any reason you went to 8mm instead of 7.62? (And the same with 13mm and 50. cal)

Probably for a perceived increase in weapon power.

Could refer to 7.92x57 (often called 8mm), and the 13x64B, possibly a hold-over from a German WWII heritage?

Overview:

The S-1 was designed to be a main battle tank, made specially for warfare in the cold and forested regions of SALVIJA. For that reason, light metals like Tungsten and Titanium are used, while the tracks are wider, to decrease pressure on the ground. Mobility was also in consideration, owing for the need in modern warfare to have highly mobile forces.

Development:

The S-1 was designed in cooperation with the military design bureaus of Solyhniya, to construct a tank, made specifically for the conditions of SLAVIJA, and the defense of her territories. The concept for such a tank went back to the 1970s to develop home made weapons systems, made specifically for Vostokjan terrain. However the idea was scrapped due to lack of funding. Interest was revived in the 1990s during the 'Armed Forces revolution" in creating a tank that was highly advanced, and highly mobile, to compete in the modern era of warfare. After many business trips around the region, Solyhniya stepped up to provide scientific and monetary support for the development of a new tank, specially made for Slavijan conditions. In 1993 the first tests began, mainly with what type of armor was to be used. For comparison and research, foreign tanks were brought in to be studied, mainly from nations like Lyras who had tendency to produce tanks in the 90 ton range. However, problems were encountered even before the imported tanks reached Vostokja. First, the tanks could not be shipped in aircraft easily, owing to their massive weight, thus the tanks had to be shipped in cargo ships, delaying testing. More problems were encountered when the tank got on to land. When the tank attempted to drive on Vostokjan roads, it was found the pavement cracked underneath the immense pressures. Thus, the tanks had to be transported in custom made train cars. Such a debacle with a heavy tank, further convinced designers, that the tank should be as light as possible. The designers, after about two months of research, forwarded three main metals, and dozens of smaller components that could be used for armoring the tank:

• Tungsten
• Titanium
• Aluminum

All these metals were chosen for relatively good strength, yet also fairly light weight. Designers experimented with other elements, such as Boron carbide, which provided considerable better protection than the other metals put forward, but significantly increased the tanks weight, which proved unacceptable to designers after the foreign tanks debacle. However the designers did not totally discard Boron Carbide as a usable metal, and it was used in limited areas in key points of the tank that needed additional protection (such as the back or top of the tank turret, and the ammo storage). For protection against small arms, designers also included a layer of Kevlar in the armor, which was cheap yet highly effective against small arms. Once the designers had secured the armor situation, development then moved on to the engine of the vehicles. The designers entertained the idea of using a turbofan engine in the S-1, due to its increased power, however the diesel engine, which was cheaper, easier to maintain, produced less heat and used less fuel, was to be used over a Turbofan engine. With the situation with the engine decided, the design moved on to two final stages, armaments and networking, with issues like countermeasures being worked on secondarily by smaller teams. The Gulf War in 1991 had proven that smaller, highly mobile and connected forces could defeat a numerically superior enemy that lacked network technology. Designers worked on installing advanced computer systems on the tank, such as a multiple phased radar array to track incoming missiles, while communications systems were installed, that allowed the sharing of coordinates, GPS tracking, and a system allowing one tank to illuminate a target, and another to fire at it, using computer compensation techniques which factored in elements like distance from the other tank, as well as elevation. Thus the design of the S-1 layed the framework for the creation of the Vostokjan BATTLENET in 1996. Finally, the designers were left with one more major challenge, armament. The S-1 would carry with it 6 anti tank missile mounter on the sides, while the main tank gun would be a rifled barrel, to increase accuracy and power. It was decided to go with a 130 MM gun, so as to be able to deliver a wide variety of rounds from the gun, even missiles. Thus with all major components of the tank complete, the designers added finishing touches to the tank.

Tungsten is not light weight. It is the opposite of light weight.

Not only is Tungsten very heavy, it is also very dense. These are two of the reasons that Tungsten is used as tank armor. Also, if you are only using Titanium, Aluminum, ERA, and Tungsten in your armor system, you are in for a world of hurt, even against older RL tanks.

Also, Aluminium burns. This is one hell of a bad thing.
