Our design needed to not only meet the Norman, but exceed it, by enough to ensure that no simple upgrades of the Cascadian design could undermine the qualitative advantage our design held. Where the Norman is, in many ways, a radically re-designed and improved T-55, SNVZ decided to take a similar approach with the far superior T-72. The result is a robust, light weight, technologically advanced, and astoundingly lethal vehicle which can be comfortably operated in all environments which it could expect to face, from the heat of the Mojave to the alpine chill of the Sierra Nevadas.

Ammo stowage arrangement The AL-type carousel-pattern automatic loader is capable of handling cartridges of 950mm overall length (technically 975 is the physical limit, but it is believed that a 950mm cartridge overall length limit allows significant room for growth while leaving some clearance inside the autoloader). It services the gun in circa 6 seconds, providing a reliable 10-round-per-minute rate of fire. It is fed by a 30-round carousel, with the cartridges arranged vertically around the turret ring. Reloading the autoloader carousel is conducted by the crew, and most of the shells are a single-person lift. Some of the more exotic types, including but not limited to 3BR1, 3BK2, 3OF1, 3OF3, and 3UBM3 are shipped separately as two pieces, and assembled during loading into the autoloader carousel due to the high projectile weight. The vehicle is provided with two hull ammunition racks flanking the driver, which are not able to be loaded from in combat and are NOT capable of storing 3BK2, 3OF3, or 3UBM3. The autoloader separates the turret basket from the hull with a steel splinter-protective bulkhead of 5mm thickness and the driver is unable to maneuver those sorts of ammunition through the loading hatch. Total ammunition stowage for the main gun is 45 rounds, 30 in the autoloader and 15 in the hull storage racks. e. FCS- relevant systems, relevant sights for operating the weapon and so on. f. Neat features. -- See Above 3. Secondary weapons- Coaxial PKT: Feeding from left to right with a disintegrating link belt. Mounted in the Mk.18 mount, and provided with 4000 rounds ammunition, of which 2000 is ready. Integrated into the main gun FCS. Commander's KPVT: The commander is provided with a 14.5x114mm KPVT heavy machine gun mounted to the cupola, with a sighting and control system for use while under armor. This is provided with 100 rounds of linked ready ammunition, and a further 400 rounds stowed in the turret basket in ammunition cans, with provision made to stow extra ammunition cans to the turret roof for quick reloads. The commander’s KPV can also be used as a manually operated anti-aircraft gun. It was chosen to provide a range overmatch against Mormon forces, as the 14.5x114mm cartridge possesses nearly twice the muzzle energy of the 12.7x99mm round, and has commensurately better long range performance. The Commander’s machine gun is provided with a 1-8x variable power periscopic optical system for use under armor, and back-up iron sights. Control is through electric motors and geared drive, and the gun can be slaved to the sight. It provides light vehicle and anti-infantry capability to 3,000m. The mount is fully stabilized and is able to be used effectively while on the move, and incorporates F50 NGVII image intensifying tubes 4. Link to Appendix 3- Weapon system magic.

Primary gunsight The TPD-2-49 stereoscopic rangefinding sight assembly is a fully stabilized rangefinder and gunsight with day / night capabilities. Day sighting is provided by two sights, a high field of view periscopic unity sight and a 3 to 12 power variable magnification periscopic sight with illuminated reticle. Night sighting is provided by F50 image intensifying tubes mounted in both the periscopic portion of the sight assembly and in the rangefinder. (F50 is part of the Night Vision Generation II image intensifier program discussed in Appendix 3, Part D: Electro-optical Program Night Vision Generation II.) Provision is made for the replacement or augmentation of the image intensifying system with a thermal imaging system when such a system is ready. The sight is arranged so that replacement of the stereoscopic rangefinder with a laser rangefinder system is possible. Range information from the TPD-2-49 is automatically transmitted to the 7M13 FCS and is included in the gun-follows-sight control scheme: the ballistic solution is continuously updated by the 5E1 and the gun aimed as the range is dialed in. As a result, firing can take place immediately after the correct range is found. 2. The commander’s hunter-killer cupola with TDD-3 optical complex is provided with a 1-8x variable power periscopic optical system for use under armor. Control is through electric motors and geared drive, and the 125mm gun can be slaved to the sight (commander's override). In combination with the 14.5mm KPVT machine gun, TDD-3 provides light vehicle and anti-infantry capability to 3,000m, as well as hunter-killer and slew-to-cue capabilities. The mount is fully stabilized and is able to be used effectively while on the move, and incorporates F50 NGVII image intensifying tubes for night operations. C. FCS: 1.

What's this? Google tells me some post-Soviet Ukrainian development of Obj.477?

Looks kind of airsofty to me, in all honesty

@LoooSeR I love it :'D Is this someone's OPFOR unit?

But... why?

Do you mean 57x347sr or 57x480r?

The exact percentage is currently under review, we haven't worked out the ERA package and side skirts The hull side in the depicted prototype does not stop several of the reference threats, however we are working on both a HIC side skirt and a LIC one which should provide the required protection The hull requires ERA to stop BGM-1 from the front, this has not been modeled as the ERA design is still in development.

Wouldn't the crew be close enough when they open the breech?

How are you ensuring it reliably follows the same trajectory, and that that trajectory can be calculated with the mechanical/electro-mechanical computers available? How does the rocket firing inside the bore effect barrel life? Wouldn't that rapidly raise the chamber pressure? If I'm reading right aren't APCP's exhaust is not good to breathe and has a prominent signature, do you have any plans to address this?

Thoughts on the Proper Use of Mechanized Forces in Defense Against the Probably Enemy to the West, Military-Scientific Thought, Summer 2250 Inspired by the current procurement of a new armored vehicle, the author has briefly made a closer study of the terrain on our axes of probable deployment, based in their experience of war in the former Nevada. The elevations in the Northern Theater of Military Affairs, excepting the Columbia Plateau on the former Oregon-Washington border and the Snake River Basin, tend towards above FL040 and in fact are often above FL050. In the Eastern Theater of Military Affairs, the terrain is likewise often above FL040 or FL050 throughout northern Former-Arizona, Former-New Mexico, and Former-Utah. Much of the terrain is above FL040, even the valleys between ridgelines in Former-Nevada, where the remnants of pre-war road networks, arid unforested scrub, and relatively flat ground allow the dushman toyota cavalry to utilize their greater tactical mobility. Worse still would be an engagement in one of the open dry lakes which dot these valleys, where their greater on road/salt flat/lakebed speed enables them to decisively outmaneuver nearly any conceivable tracked vehicle, and attack the sides/rear with their powerful anti-tank means. The peaks which separate these valleys are dominating terrain features, often rising above FL100, however the limited engagement ranges of current fire control systems mean that the ability to observe often the entire >10 mile width of the valley (weather permitting) is hampered by an inability to engage the targets observed, at the least with tank gun fire. An interesting conundrum, no doubt. It is conceivable that the very high caliber guns being pursued by the various parties of this competition may be able to engage such targets, using fire by direct aiming to deliver HE-FRAG, VT, or DPICM against the lightly armored opponents. On the other hand, this job could be better accomplished by heliborne light infantry with long-ranged ATGM and a light, airmobile SPH of c.4.75" caliber able to fire shells to 10 miles (15 with RAP), and effective aviation support (fixed or rotary wing). The low "footprint" of the light infantry soldier, in comparison to the heavy mechanized unit, would reduce sustainment needs relative to armored forces, and reduce the effectiveness of enemy ISTAR means. A mission-tailored task grouping based off of an airborne infantry regiment could take any point in the whole of the Newark and Diamond valleys to the East and West under fire, and direct air and artillery fires against throughout Eureka, White Pine, and Elko counties. A lower profile force could be used, consisting of a network of observation posts with long-range radio systems to plot enemy movements, and use rotary or fixed wing aviation to "herd" or channelize the zealots into coordinated fire-strikes using high power artillery or the weapons of our illustrious rocket-missile troops. Indeed, we need a unique kind of vehicle to support this style of warfare. Tentatively termed "4th Dimensional" (three dementions+3D cross domain personeuver) warfare. While past authors have spoken of similar needs for high speed tracked vehicles for this purpose, due to their higher cross country ability and greater protection than wheeled death traps, their suggestions, derived from the pre-war M113 Gavin APC, would be hopelessly outclassed by the toyota cavalry of the mormonhideen. Thus, inspiration should be taken from the pre-war Combat Vehicle (Recconaissance) Tracked series of vehicles. Of particular note are: FV101 "Scorpion" light tank, so named for the 'sting' of its 76mm gun FV-107 Scimitar Reconnaissance vehicle, armed with a 30mm cannon and named for the famous sword of the Medieval Arab cavalryman who's descendants perfected the toyota cavalry concept. FV105 Sultan Command track, allowing the 4th Dimensional personevuer commander to keep pace with their subordinates even in the highest tempo actions FV102 Striker ATGM carrier, able to sling lethal highly maneuverable missiles from outside enemy gun ranges FV103 Spartan Armored Personnel Carrier, as light and maneuverable as the light infantry inside, with low ground pressure and good power to weight allowing it to be far more of a 'go anywhere do anything' vehicle than the "jeep" of WWII However, the modern requirements of today require a new approach, and some new vehicles. The Light Tank would need increased lethality compared to the pre-war 76mm, for example, and a 4.75" howitzer motor carriage would be required. Further additions may include an engineering vehicle, Anti-Aircraft gun motor carriage, and a mortar carrier. Armed with these new vehicles, light infantry forces would be able to move faster, across, through, and over worse terrain, with heavier weapons, than the mormonhideen. The efforts of the Armored Branch to continue investment in over-complicated expensive vehicles is indicative of the decadence, sedentaryism, and intellectual lethargy which has arisen within the Armored Branch. One might reasonably expect such simple-minded solutions from the robotic money-grubbing degenerates in Cascadia or insane religious fanatics of the tribes who inhabit the Eastern wastes. To see such behavior within the PAF Armored Branch is beyond the pale. Instead of thinking of new ways to skin cats, our fellow officers might best be thinking about how to herd them. -Colonel Miguel Chispas, 1st Tactical Studies Group (Airborne)

I mean if you want to build a tracked light cruiser...

Astrolite has an 8600m/s detonation velocity, though?

Astrolite A/G has better brisiance, iirc

Report from Lt. Col. [REDACTED] People's Auditory Forces Directorate of Political-Moral Reliability, Auditory and Political Officer for SNVZ and Military-Industry Liaison Officer for RFP "New Battle Tank" Today, exaltedly equal comrades of multitudinous genders, or none at all, I have wonderful news! We will be discussing the ammunition and developmental armor schemes for the SNVZ AFV-50 project. First the ammunition types. High Explosive-Fin Stabilized The primary general purpose support round for the vehicle, equipped with a standard and super quick fuse setting M/V in excess of 500m/s 6.32kg of TNTe filler High Explosive-Fin Stabilized-Urban A “supercharged” HE-FS round designed for short range demolition work 19.88kg TNTe filler Armor Piercing Capped Ballistic Capped-Fin Stabilized The Primary Anti-Armor kinetic energy round Using highly energetic bursting materials, we have achieved devastating beyond armor effects Meets or exceed armor penetration requirements Armor Piercing High Explosive-Fin Stabilized Base Bleed A long range anti-armor round Base bleed reduces drag (and thetan level) throughout the projectile’s flight to ensure optimal retention of auditory capacity. [AUDITED] [AUDITED] [AUDITED] [AUDITED] Chemical Effects-Anti Tank An anti-tank projectile which generates its armor penetrating effects from chemical energy (explosives) within the round Multi Chemical Effects Shell A heavy chemical effects shell with improved explosive qualities at the expense of range and velocity to improve the numbers of use cases. These shell types will allow the AFV-50 to engage and defeat all known and planned enemy combat vehicles should they foolishly decide to attack the peace loving peoples’ republic. They are effective at all combat ranges, allowing the gun tank to decisively deconstruct aggressions, micro and macro, and fulfill its combat tasks. Secondly for today, the SNVZ collective would like to discuss the early development of our armor schemes. While it is a capital offense to shame for weight, it is important to note that later design iterations have exceeded initial goals. Truly SNVZ and the AFV-50 program have been blessed with the bounty of L Ron Hubbard Thought and it is important to recognize that our vehicle is healthy at any size. Recognizing the threat posed by CE warheads, the design team initially investigated the use of large volumes of Glass Textolite, alongside steel. (Fig.1) Unfortunately the thicknesses required were rather extreme, and resulted in deep inefficiencies. Fig.1 To compensate for these deficiencies the ratio of steel to textolite was increased, however this also increased the weight. The integration of layers of ceramic and High-Hardness Steel was investigated, however the density/areal density of these packages was deeply unsatisfactory. (Fig.2) Fig.2 At this time the collective investigated various arrangements of so called “Special” or “Composite” armor arrays. They were found unappealing due to the large volumes needed to contain them, and the angles required for best performance. (Figs. 3, 4, and 5) Fig.3 Fig.4 Fig.5 At this time it is unclear what growth potential the Cascadian tandem-HEAT warhead may have, and/or the Mormohideen 2”/4”. These high lethality threat systems may not be able to be defeated without elaborate and economically infeasible exotic armor schemes, in the view of the SNVZ design collective. At this time the SNVZ collective is pursuing further armor concept development, but it appears that the weight and size of tanks must increase drastically before adequate levels of protection are possible. Therefore it appears that the medium tank as it is known, cannot be survivable on the modern battlefield. The Cascadian introduction and adoption of the <<Norman>> series appears in hindsight to be a drastic misstep. The current service variation (NORMAN-A) appears to utilize conventional steel armor materials in a relatively novel layout. However, this is hopelessly outclassed by modern tandem charge CE technology. The Cascadians appear mindless stooges of chauvinist revanchism and warmongering, however despite their perfidy, they are not stupid. They are likely to be investigating the potential for equipping a derivative of NORMAN-A with exotic “special” or “composite” armor systems. They are fools for doing so! To defeat modern tandem-shaped charges would require far too much volume and weight of armor to fit in a traditional “medium” size tank. But the Cascadian dogs have made their bed, and so they shall sleep in it. They may as well have introduced the kite shields and chainmail of its namesake, for the good it will do them. In the modern threat environment, where tandem charge ATGMs outrange the ability of armor to detect and engage them prior to, or even after, launch, the Medium Tank is dead! For this reason, the SNVZ AFV-50 designs have blossomed through the iterative process, between 20 and 25% over the initial predictions. Fortunately there is historical precedent for such a matter. Ancient pre-war historical texts speak of a mightily effective Main-Battle Tank, the first of its kind. During the Second Great War it was created, and grew through its design process it grew to just over 1.25x the initial design goal. The Tank Struggle Vehicle Mark 5, or “Panther”, was widely regarded by the ancient sages of the “AxisHistory” forum as the best tank of this second of the great wars, with armor, mobility, and firepower an order of magnitude above the delicate, vulnerable, underarmed and expensive Medium tank M4 "Ronson". Clearly in light of this the weight gain of the AFV-50 is not of much relevance. Collective efforts of SNVZ to improve armor protection continue, and appear to be reaching some success. The DPRC, guardians of the people and L. Ron Hubbard Thought, as well as our most eminent and wise leadership, the most Gracious and Serene Majesty Queen Diane Feinstein the VIII, require cheap winners, like the TSV Mk.5 "Panther" of old, rather than "expensive losers" like the "NORMAN" or "Ronson"! On this matter, I assure you that the shock-engineers of SNVZ will deliver!
