Overview

During the Leocardian Civil War, a band of nations came to the aid the political power of Leocardia. After the end of the war, agreements and plans to rebuild infrastructures and civilian buildings that were attacked by rebels was the topic. It was then realized that even the radical rebels, that received limited aid from Mationbuds, had more powerful tanks than the Type 99 MBT and the LMT-32J inventory in Leocardia's Armored Division. With Lord Sumguy's offer to aid Leocardia's Armed Forces during national reconstruction, it was thought of that Leocardia's Army was more obsolete than thought before.

A band of nations, primarily USSNB, Leocardia, and TWSP, joined together in a joint tank development to develop a modern tank that would be ranked as one of today's most finest tanks ever made in the modern world...

A Northern Baltic produced Type 5 Rapid-Autoloader can be provided for the tank.

Type 5 Auto reloader? How fast is that?

I propose the 67AAM53 Leocardian Autoloader.

Unless, we can joint develop one.

The Type 5 Autoloader can shoot up to 15 shots per minute using a Northern Baltic Type 2 130mm gun.

The Type 5 Autoloader can shoot up to 15 shots per minute using a Northern Baltic Type 2 130mm gun.

We can upgrade the tank gun and loader to a modified version with a 135mm gun and a variant of your Type 5 into a Type 5A.

And then, we can use the Leocardian LGH76/MTH-32 2,500HP Twin Turbo Engine + powerplant.

Perfect.

TROPHY APS requested.

OOC: Im willing to collaborate, if possible, since I need a new "Support Tank" to replace the Leopard II.

Welcomed in.

LASER Self-defense/warning system requested.

Welcomed in.

Well, just for addage, if you guys ever design a tank-hunter (I wanna design one, and it would bother me if we pooled our efforts), we can use my custom-designed M06 Tank Buster Gun.

As for a MBT, I can provide:

-Soviet Automotive Industries Combat Model 1, WSP-V24-UF-M1 Liquid-cooled, V-12 cylinder, 64.0-Litre, 4-stroke exhaust, Universal Fuel Engine (Primary: Biodiesel), developing 2,300hp (1,905 kW) @ 2,600 rpm

And

Soviet Automotive Industries Combat Model 1, WSP-APU-M1 Liquid-Cooled Biodiesel Auxiliary Power Unit generating 160kJ for Vehicle Subsystems

I'm for the Soviet engine. The Leocardian one is still under experiment.

Lord Sumguy can provide a locally designed RB12 mark V "Spinning Jenny" turret, wich contains two rotating barrels for faster firing, loading, and barrel cooling. As one barrel is fired, the other is loaded, and after firing, the barrels rotate. This may nearly double a tank's firing rate with combined with a high-quality autoloader. It has been our focus to make armor that can fire very quickly in a short amount of time, as we usually use hit-and-run tactics on the battlefield.

The rotating barrels sound like a bad idea.

Hope you don't mind me butting in.

This sounds good, but there are 2 main problems-

1. the added weight - you would need to sacrifice some armor
2. you would run out of ammo too quickly. You could always bring more, but that adds more weight (see above)

Wider tank proposed.

this is true, which is why any tanks using this would have to be either very large and contain a very powerful engine and therefore sacrifice speed, or be a hit-and-run light tank.

Doubtful.

OOC: Tag for reading.

Wider tank proposed.

I'd accept the wider tank, if it meant a lower tank. Remember the guns on Soviet tanks can't go down that much, which would give us an advantage over them.

Define lower and wider.

Define lower and wider.

If we make it wider, we can make it smaller. However, I say we keep it the regular size, but add two engines.

Two engines for faster movement, I like it.

I'm wondering about the weight cost now. Modern tanks can devastate roads and bridge just by rolling over them. Then there is air transportability when it comes to wider, heavier tanks. Also bridge crossings, and how wide roads are. You don't want your fancy new tank to find itself unable to fit down some crappy little town's streets.

I'm all for NS improvements, but this seems like extreme overkill. I manufacture a power gas turbine engine but nowhere near this kinda overkill. To compare, we can offer the Abrams as a comparison.

AGT-1500 multi-fuel turbine engine, Honeywell LV100-5 turbine engine
Allison DDA X-1100 3B transmission
1500 hp (1119 kW)

And the Leopard 2's main engine is probably a better comparison.

MTU MB 873 Ka-501 12-cylinder diesel
1,500 HP(1,103 kW)at 2600 RPM.

None of the major main battle tanks today manufacture an engine over 1,500 hp, and those over 1,000 hp are usually gas turbines. To compare, his engine is nearly double that of the Challenger's while being structurally similar.

Two engines for faster movement, I like it.

That will make it to bulky.

As for the secondary armament, I recommend the usual, you know, 7.62s, Remote Controlled 20mm on top of the turret, smoke dispensers, etc.

OOC: What about that engine TWSP?

IC:

We'd like to offer the 140mm ETC 55 caliber smoothbore gun. Its longer, also autoloading cousin, is the standard naval gun on my frigates, destroyers, etc.

As for secondary armament, we'd recommend a tiny Stinger Missile Pod fitted into a slot opposite the side the coaxial weapon is placed. With just 2-3 missiles you can offer a serious threat to helicopters and help keep those annoying bastards at bay.

We have become interested in this project and would like to offer a number of products, including an engine that we have developed with the USSNB.

It is an experimental six-stroke engine that after the fourth stroke, injects a bit of water into the cylinder, which rapidly expands to 1,600 its original volume, adding another 2 strokes. This results in a minor improvement in efficiency and results in an increase in horsepower.

The X55JLNB6000 6 stroke Diesel engine, producing 1,600 hp. The only downside to this is that there must be an addition of a watertank to allow the 5th and 6th stroke to run.

However, soldiers in the desert find this feature tremendously useful, as they cannot drink diesel, but can easily refine the water to drinkable condition.

We also offer the 55 caliber 140mm ETC gun, which is autoloaded like its antishipping cousin, found on all Leafanistani Frigates and Destroyers.

And finally, we offer a rice cooker like hot plate that will heat water for your troops. While this seems like a novelty, the ability to enjoy MREs within the safety of the tank, or use the tank like a kitchen is tremendously useful in boosting troop morale.

we would like to take an order of 40 of these as soon as they are complete.

unfortunately, our armor designs are inferior to thoise of the Northern Baltic and Leocardia, is there any other way we could contribute? raw materials and manufacturing i suppose, since our economy is entirely based on the automobile manufacturing industry.

We can use your nation to mass produce this tank, as well as making prototypes and testing crafts before we make our final version.

I will accept Leafanistan's Diesel engine for the tank.

How does a rotating barrel increase the rate of fire? You might be referring to the autoloader rotating the rounds into the breech, like on a revolver. But, I don't see how a 'rotating barrel' makes very much sense.


Modern tanks can devastate roads and bridge just by rolling over them.


Well, modern tanks shouldn't ruin paved roads. All modern tanks should have pieces of rubber replacing the surface areas of the track that will hit the pavement. It's what allows tanks to participate in military parades - and all modern tracks include rubber. They don't really 'devastate' bridges, either; they are either too heavy or they can use the bridge.


None of the major main battle tanks today manufacture an engine over 1,500 hp, and those over 1,000 hp are usually gas turbines. To compare, his engine is nearly double that of the Challenger's while being structurally similar.


Only two tanks use a gas turbine - the T-80 (and the T-80UD and T-84 use diesels) and the M1 Abrams. The Leopard 2, Challenger 2, Type 99, MBT 2000, T-90, Merkava, et cetera, all use diesel engines and all of them produce over 1,000 horsepower at the sprocket.

My two cents on any main battle tank's main armament. Mostly, this is an argument for smaller caliber guns, instead of increasing the caliber. The point of increasing the caliber in the 80s was to defeat a projected Soviet threat which could not be defeated by existing 120mm solid propellant smoothbores and rounds. It was thought that the solid propellant had reached the end of its development (and it might have). Despite the increase in energy using a 140mm gun, the 140mm gun is heavy and will require a much larger tank - even minute changes in the amount of volume of a vehicle can drastically increase the weight. Furthermore, a 140mm L/55 gun will measure 7.7m. This is 1.1m longer than the 120mm L/55, and over 2.5m longer than the 120mm L/44. It's best to compare to to the 120mm L/44. The longer a gun the less accurate it will be - the longer it is the less torque needs to be applied to move it, meaning that it will shake more dramatically when on the move. This will affect accuracy on the move and just when the tank stops - and fire control systems can't solve all the problems accurately.

You can achieve similar energy increases using alternative energy sources for a 120mm gun. These include liquid propellants and electrothermal-chemical ignition of solid propellants. Interestingly, there has been some news that maybe they will actually decrease the size of the main gun on future tank designs to 105mm!

This was just a short anecdote to help you pick out what armament you may want to use on your future tank.

Equipped with Leocardian MPT32S antistealth/nightvision radar

I'd like to offer you the use of the LY105 30mm automatic cannon as either a co-axial or remote turret weapon.

The LY105 is a single barrel, externally powered (4 HP electric motor), electrically fired weapon. It is mounted on the forward right section of the Warhound's turret, coaxial to the main gun. It fires 30mm linkless ammunition at a rate of 625 ± 25 rounds per minute. The LY105 has a positive cook-off safety (open bolt clearing) and double ram prevention. It uses the following shells, loaded at unit level:
LY89 High Explosive Dual Purpose (HEDP) rounds for anti-armor and anti-personnel
LY99 High Explosive Incendiary (HEI) rounds for anti-personnel and anti-materiel
API (Armor Piercing Incendiary) (DU) 30mm Ammunition

We use the very same piece of kit as the co-axials on the LY3A1/2 Warhound MBTs that we're offering at the moment.

Anti-material rounds requested.

OOC: So you guys know, Leafanistan was wrong. Your initial 64L engine would have been able to produce the power you needed. In fact you could have gotten the power from a 52L engine just as easily, and for only slightly larger then the engine Leafanistan has offered you (Which looks strikingly simmilar to an engine I posted on The Draftroom a few months back).

Request for HEI rounds as standard acknowledged, and accepted.

While we do not wish to utilise this tank in our arsenal, given our satisfaction with the recently in-service LY3A2, we are watching with great interest, and think highly of this new international design.

Incidentally, this LY105 30mm automatic cannon is extremely nasty, and the HEI rounds you have selected for it is a good choice.

For the engine, and armour, we are willing to tender offers, if you wish to have them.

Payment for the LY105 system can come after you sell the tank to someone else. Profits from the sale of the Warhound MBT have given us leeway there.

The LY105 can take other 30mm ammunition, if needed, but we'd recommend our own, which is designed specifically for this system.

as well as making prototypes and testing crafts before we make our final version.

very good...i can use them in the conflict ia will soon be entering...

OOC: Curses! Well, you live and you learn.

As for copying your engine, the latest Popular Science has an article about a guy who made a six-stroke diesel using steam power. I just copied him. I find weapons innovations usually follow publicity about actual innovations.

Bump for curiosity.

i would freely give you the Uprgraded NC greal v-66 diesel engine(1,800hp)

Or, if the engine submitted by North Calaveras that engine isn't to your taste, then we offer another piece of kit that we have already used on the LY3A1/2 Warhound.

The 2,500 hp LYM 663 Bw-404 V12 diesel outputs (2,303 kW) at 2600 RPM. It features a (four forward, two reverse) Lyran-Allison Hydro-Kinetic automatic transmission, giving a 75 tonne tank (the Warhound) a governed top speed of 82 kph (51.25 mph) on paved roads, and 58 kph (36.25 mph) cross-country. With the engine governor removed, speeds of around 112.5 kph (90 mph) are possible onroad surface; however there is a greatly increased risk of damage to the drive train or tracks, and these speeds tend to greatly degrade road surfaces. 440km is the operational range of a 75 tonne vehicle, using this engine, and the engine is capable of taking any petroleum fuel, from bio-diesel to petrol, or even crude oil straight off the tanker, although we'd advise against the latter.

The engine governer can be set to “off” by the commander if the circumstances require.

Importantly, on a 75 tonne tank, this engine delivers a whopping 33.52hp/t, which, while not affecting top speed, will markedly affect acceleration.

we are only a small nation...we would like to offer somthing, but we do not have much to offer....our main exports are cheese, soda and restored Furniture

maybe we could offer labor or some such, we are a new country and do not have much of an Army and would be interested in the final product



thank-you for hearing me out

OOC Verenberg, check telegrams.

So, here is a basic picture of the tank http://www.military.cz/russia/armour/tanks/t94/t-94.jpg. We have yet to add the dual remote control Kord Machine guns and the external equipment, but its what the basic hull looks like. Armed with a 135mm gun. Rifled or Smoothbore? Both will fit.

I say rifled. More accurate (right?)

The glorious innovators of Keotonia have developed highly accurate fire-control computers ballistic weapons, meaning sabot rounds can be fired from a smoothbore gun, thus achieving higher velocities and reducing barrel manufacuring costs!!! :mp5:
Coupled with the guidance computer, this system allows true one-shot, one-kill capability for main battle tanks.
POINT AND SHOOT!!!

Okay thanks for the responce, gents. Okay so the tank hull picture and the 135mm rifled gun is fine. Thanks for your input. Anywho, I say we devolp our own stuff to put on the tank, or at least be able to produce it. I don´t want it ending up like the Lion of Babylon MBT.

I say we equip our men in those tanks with a special submachine gun designed for their type of position. I propose the CQ Submachinegun.

You know I use the PP-2000 Submachine gun, Leocardia.

You know I use the PP-2000 Submachine gun, Leocardia.

Okay.

Okay so yeah. Crew of three. Commander, Driver, Gunner. They´ll be kept in a seperate compartment from the ammunition (thanks to the autoloader) which will increase survivability.
