NPM-A SPW-05 Armored Assault Gun

Program:

The SPW-05 is intended as an infantry support weapon, to replace the ageing PT-76 Light Tank currently in service.

Generally seen in a support role, it is intended to provide short-range artillery support and anti-tank fire for whatever infantry it is attached to, as well as give its attached battalion an amphibious vehicle with at least the firepower of the PT-76. It is also highly capable of providing transport for any number of infantry who can fit on its flat hull.

Design:

Laid out in the same basic format as the PT-76, this vehicle has a driver compartment located alongside the diesel motor at the front of the vehicle. Mounted directly behind the driver is the main gun, set in a squat position, far back in the vehicle, protruding over the driver’s head. Also behind the driver is the commander/gunner’s compartment, complete with traditional soviet auto-loader and open ammunition/fuel compartment.

Armament:

The main gun, with a 7.5 cm bore, is actually an adoption of the traditional 75mm artillery tube used by Novikov’s military. It is well capable of firing traditional, low-velocity artillery shells, as well as it’s more common armament, the high-velocity/high-penetration 75mm anti-tank shells (HV/HP AT) designed to knock out tanks with armoring comparable to the modern T-80 soviet medium tank.

The main gun is not fully stabilized, rather being in almost a rigid mount to the vehicle frame. This prevents it from firing accurately while moving, but there is no firing inhibitor. Thus, it can still engage with reasonable precision at short distances, even while in a full run.

This weapon is targeted using a modern laser-range finding system, as well as a basic ballistics computer, digitally connected to the typical thermal barrel sleeve. This gives it pinpoint accuracy at up to two kilometers downrange in ideal conditions. It is, however, missing some of the more advanced systems like those measuring wind speed and barometric pressure. An onboard GPS system also allows infantry to digitally map targets for beyond-vision engagements while the gun is serving as artillery.

A wide visual range is achieved via a pair of periscopes, as well as a similar pair of IR equipped panoramic sights, one for both driver and gunner. This allows the gunner to independently engage targets while the commander operates the secondary weapon, and allows full targeting options even if one sight is disabled.

Secondary weapons consist simply of a 12.7mm machinegun mounted alongside the main gun. Firing is controlled by the vehicle commander, who engages out his traditional panoramic sight. Because this was intended to operate alongside groups of SA-7 equipped infantry, it has no air-defense weapons.

Protection:

The hull is of a typical hardened steel construction with 3mm composite overlays. A sloped front and sides attempt to provide increased deflection of incoming shells (with mixed results), and a steel skirt can be applied to protect the otherwise vulnerable tracks. Its armour, however, is a mere 25mm thick in most places, giving it only marginal defense against small-caliber weapons.

Because of this, the SPW-05 is not intended to stand up to hostile tanks and its best defense is simply not to be seen, as its armor cannot stand up to the main weapon on any modern medium or heavy tanks.

If it is spotted, its last defense is in the form of a modified JD-3 integrated laser rangefinder/warning/self-defense device. Just like that on the Type-03 Main Battle Tank, the JD-3 detects incoming laser beams (presumably from a hostile tank’s rangefinder) and fires a parallel beam back at the source with the hope of blinding the computer targeting system on the enemy tank. The SPW-05’s version of this system, however, features a varied-intensity beam, rather than the simpler standard-intensity beam mounted on the Type-03. The varied-intensity was chose because it forces the enemy computer system to make rapid re-calculations, simulating a rapid change in its target range. This serves to hinder targeting ability by almost 60%, giving the SPW-05 a reasonable chance of survival, even if detected and engaged by a superior main gun.

Propulsion:

The Type-03 is powered by an air cooled, turbocharged 800 hp diesel derived from a compacted version of Germany’s WD396 diesel technology.

Again an excellent weapon system and its amphibious capabilities are quite impressive, and useful in our (the mekugian) terrain. Though we have no used Assualt gunsin quite some time, we have always liked the style and its affectiveness. A 120mm Gun/mortar system has been in the works for awhile but has been held up for several years due to governement regulations, but that does not need we dont have use for such a system, and as such would like to purchase 58 vehicles to suppliment both our type-O3E and Karak LST's

We are also interested in purchaseing the production rights for the Variable intentsity JD-3 Laser Rangefinder/warning/self-defense device as to update our existing stocks of '03E's and our curious as to how much you would like for those designs.

In return (as well as paying in cash) several engineers at a local company (Horizon Heavy Industries) have proposed a New amphbious upgrade kit for the O3 which replaces the old transmission, with a new system with an additional gear that is used to power dual steerable water jets, and adds a small folding trimvane to the front of the vehicle. This also adds additional (though minor) protection for the driver.thish should give ti a water speed of around 4-5 kph which though not that fast, adds even more capabilities to an already astounding vehicle.

Our total for the SPW-05 should come to 69,600,000.00 USD which should already be enroute, and the payment for the rest (should you be willing to accept it) will be sent upon confirmation of the order.

The Emperor of Trolsk would like to send his congratulations on the development of such sophisticated technology. First bit of business. The Holy Empire of Trolsk has a strong Arms manufactoring ability, but is severely under-equiped. We ask to buy in bulk 100 of these SPWs, to begin the re-armanent of our military. We will pay the 160,000,000 in one lump sum. Not only that, we request you look for our Emperor's request for Arms Trade Licencing in our own political topic. It will be most pleasurable to do business again, and hope this transaction can be completed quickly.

Mekugi:

There are two problems with your request which must be reconciled before any shipment can be made. First, the JD-3 VI is perhaps the most important single system to Novikov's ground forces and, as such, we are unable to sell it to anyone save our closest allies. On traditional export models, we replace the JD-3 VI with a weakened version of the origional JD-3, still capable, but with some limits on the technology so as to protect ourselves from the possibility that these arms may be used against us. Needless to say, we are not willing to sell this technology.

Secondly, we wish that you recognize the fact that export cost of this vehicle is set at 1.600.000 USD per unit, bringing your request to 92.800.000 USD, far more than the 69.600.000 USD we have yet recived. We will be able to fill your order, provided the mentioned problems are fixed.

Trolsk:

As with Mekugi, it must be stated that the JD-3 VI is perhaps the most important single system to Novikov's ground forces and, as such, we are unable to sell it to anyone save our closest allies. If your government will settle for the origional JD-3 model with a reduced output, perhaps 45% of the origional effectiveness, we will begin shipments in one year.

((OOC: Did I suddently fall out of favor of the IADF?

Production Cost: 1.250.000 USD
Export Cost: 1.600.000 USD
Export Cost (IADF Allies Only): 1.200.000 USD

1,200,000.00 USD x 58 units = 69,600,000.00 USD or so my calculator tells me...

or does that no longer include me? ))

Just a suggestion, Id add some ATGMs for anti-tank work, maybe 8 or 10, thatll level the playing field against more modern MBT's.

My list of the IADF is somewhat dated. Please forget my comments to you. We would be happy to sell you the origional units, and shipments will begin today, with transport completed within the month.

We would like to purchase one SPW-05 in fully equiped format for combat testing in our Tank facility in Nineveh, with the possibility of further orders for our Territorial Gaurd units.
Furthermore, we would like to purchase two SPW-05's for the purpose of modification with our technology, and testing as thus, to compare with the origonal and see what would be needed to meet our needs.
We would be happy to have a representative of your design team accompany the vehicles if they wish to witness the testing and devlopment process, as well as we will gladly share any devlopments we make.

The order should come to $3,600,000 for all three vehicles.
Thank you.

We would be happy to provide our allies in Dostanuot Loj with our new Assault Guns and we feel that this preposal you have made would constitute a major oppertunity to see the combat effectiveness of the SPW-05 design. The entire SPW-05 design team, therefore, will be transported to the Nineveh facility, wiht your government's graces of course, for the purpose of supervising and recording combat test results, as well as helping with possible modifications of the basic SPW-05 design.

Your design team is more then welecome at the Nineveh facility.
As has been said, we will be outfitting the two test vehicles with various new systems, including two new weapons systems.
We plan to test the SPW-05 with one of our 120mm breech loading mortars, which have become very popular among motorized mortar units and Urban warfare units. We will also be testing various hyper velocity main guns in the tank destroyer role, including a new variant of the 75mm hyper velocity cannon we use in our light tanks, and possibly an 80mm or 90mm variant as well.
Also, new powerpack systems may be tested, as well as various add-on armour systems.
This would be the perfict oppertunity for a light Assault Gun/Tank Destroyer to compliment the heavier variant that we will be implimenting shortly.

We are all eager here in Poloski to see these new design preposals you have mentioned, though we must also caution you that the amphibious capability may be compromised with some of the heavy additions you are suggestion. Regardless though, we will be looking forward to our trip to Nineveh.

Assault Gun Testing and evlopment: Nineveh (http://forums.jolt.co.uk/showthread.php?t=404386).

And one final OOC Question. You say it's based on the PT-76 but with the gun way back, and the engine beside the driver. So.. does it look like the PT-76? Which has the gun forward in a turret, and the engine in the rear, or is it based more on the Su-76 assault gun of the WW2 era?
And of course, turret or no turret? It's a little unclear (Yes, some assault guns have had turrets.)
