StuG III Thread (and also other German vehicles I guess)


Recommended Posts

Some info regarding Rheinmetall's KF41 Lynx based on the current Wehrtechnische Report of the Mittler Report Verlag:


The Lance 2.0 turret is being offered with two configurations; internal missile launcher (probably the one designed in cooperation with SupaShock for Australia) and the already show-cased confiugration with two external mission pods. Apparently one configuration envisioned by Rheinmetall is to use one mission pod for a dampened dual launcher of Spike-LR ATGMs, while the other is to be fitted with an electronic warfare package.


When fitted with the MK30-2/ABM autocannon, the elevation range is -10° to +45°. There is storage for 252 ready rounds, reloading under armor is possible from the gunner's seat via a hatch. Main gun ammo and anti-tank missiles are stored in compartments separated from the crew in order to increase post-penetration survivability; no idea if there are blow-out panels. The 30 x 173 mm KETF ammunition is the only 30 mm airburst ammunition that has been fully qualified to NATO standards, but for customers wanting cheaper ammunition, a HEI-T and a SAPPIE-T round have been developed. Secondary armament is a coaxial 7.62 mm machine gun with 750 rounds. The electrically-powered Wotan 35 gun is still not fínished, but will be available in the near future.


Rheinmetall has developed the SEOSS-2 as successor for the current SEOSS sight. The basic functionality (LRF, daylight camera and thermal imager; all signals are transmitted electronically to the FCS & displays) is comparable to the original model, but sensor resolution has been improved. The SEOSS-2S (sector) designed for use as a gunner's sight has 15° traverse (-7.5° to +7.5°) and covers elevation from -13° to 70°. The SEOSS-P (panorama) provides the same elevation, but 360° traverse. It can be fitted with a ballistic cover for protection according to STANAG 4569 Level 3. The SEOSS-2P can be adapted to act as RWS as part of the Main Sensor Slaved Armament (MSSA). The fire control system of the KF41 Lynx includes features for automatic target detection and target tracking.


As already mentioned in the LAND 400 topic, the Lynx makes use of a six-cylinder in-line diesel engine from Liebherr with 18 litres of displacement and double turbo-chargers to reach a boost output of 850 kW and a constant 800 kW. Between 1,200 and 1,900 rpm, the torque is constant at 4,300 Nm. Maximum engine speed is 2,300 rpm. The transmission is Renk's excellent HSWL-256 as fitted to the Puma IFV and the AJAX family of vehicles.


The current situational awarenss system from Rheinmetall uses the SCM 60 (surveillance camera module) that is also part of the Boxer CRV and the Puma S1 upgrade. It combines a 1,600 x 800 pixel daylight camera and a 640 x 480 pixel thermal imager with a 60° fíeld of view. The Lance 2.0 turret features six SCM 60 modules. The software allows fusing the outputs of thermal and daylight optics together. The driver's night sight is the RFEL Trailblazer.


They Lynx makes uses of Rheinmetall's xGVA, which is fully compatible with the NGVA (NATO STANAG 4754), the older and less comprehensive British DefStan 23-09 GVA and the DEF (AUST) 11316 Australian GVA.


While Rheinmetall has only showcased one configuration of the Lynx, the company is willing to adapt to the customer. Both its own Ragnarok mortar and the Patria Nemo turret are available. Likewise steel tracks or Soucy's rubber band CRTs are available, though the later only support a GVW of up to 47 tons. Armor concepts are also designed for a wide range of threats including passive and active protection (i.e. ADS as hybrid protection module) systems against RPGs and top-attack threats.

Small follow-up to the last post.


Here are some pictures from the inside of the Lynx, i thought i may share it as there hasn't been much shown of the internals.

Very clean and tidy if you ask me.


There are also photos from the interior of the turret. Unfortunately the image resolution on the pdf versions is always so low...

Hilarious - the G in all these is Generic.....  The intent always was exactly that - generic.  Yet here we go with manufacturer and organizational unique "generic" architectures :)

The US also has its own standard, though it is also to some extend compatible with the NGVA. The problem is that the UK and the United States didn't want to wait for a NATO standard and started their own project(s), then split up and went into different directions.


The UK ended up with LOSA (Land Open System Architecture) that contains their GVA (DEF-STAN 23-13). The US ended up with Vehicle Integration for C4ISR/EW Interoperability (VICTORY). Meanwhile NATO - in form of OCCAR - searched for a common GVA as part as the LAVOSAR I (Land Vehicle With Open System) project, with further enhancements being added by the LAVOSAR II project. The winner of the open tenders for LAVOSAR I and LAVOSAR II was Rheinmetall, which leveraged most of its experience gathered with Boxer and Puma, while also making changes to Puma. Funnily enough the LAVOSAR project was initiated on behalf of the MILVA (Military Vectronics Association) which includes both the UK and the United States...


LAVOSAR became standardized by NATO as STANAG 4754 and has since been called NGVA; the Puma IFV is the first NGVA compliant vehicle.


LOSA, VICTORY and NGVA are all interoperable to a certain standard, but NGVA encompasses more stuff (incl. common interfaces for active protection systems and unmanned systems). Apparently VICTORY also requires some hardware changes - at least some companies are offering parts compatible with LOSA/NGVA and separate parts for VICTORY. No idea how AS GVA (Australian GVA) fits into the picture.



Interoperability between different countries is the last step of fully adopting a GVA. First step is interoperability of all components within a vehicle, followed by adopting the common GVA for all vehicles in a country.

Can you post some information about that prototype for us who don't know it? Thanks. 


Maybe me knowledge will suffice as well.


This is the VT-001 (Versuchsträger) prototype of the Marder 2 vehicle.

With the introduction of the Leopard 2 there was a need for a new IFV that could keep up with the MBT, both from a mobility and technology standpoint. The German army then put the „Kampfwagen 90“ to life. The requirements were then given to the manufacturers (KMW main contractor) to come up with an offer. Main requirements were for the vehicle to carry at least 7 grenadiers and to protect them against 30mm AP(DS) munitions on the frontal arc.


In theory the armor concept was to be modular, but due to the heavy weight (44t) this was wishful thinking. The armor made the vehicle immune to 14.5mm AP all around, with the already mentioned 30mm protection on the front. It also had a spall liner.


The main armament (found in the rather cramped 2 man turret) was the Rh503 35mm external propulsion gun.




An innovative concept with quite a lot of firepower for its time (even upgradeable to 50mm if the need arises) with then newly developed Oerlikon APFSDS rounds and just like the modern Puma it had a programmable HE round against infantry. While the Marder 2 for some reason had no anti tank missiles, a major upside compared to the Marder 1 was that the gun now was fully stabilized.


Powering the Marder 2 was carried out by the 1000hp MTU Ka-500 from the Pzh2000 and the same gearbox from Renk which is also used on the SPH. The propulsion allowed for top speed of 60km/h (which produced an unpleasant sound for the passengers). In contrast to the Puma the Marder 2 relied on a torsion bar suspension system.


The fire control computer was a modified version of the ATLAS FLT2 found on the Leopard 2. 

The gunner was supposed to use the PERI-ZTWL sight, which was very similar to the EMES-15 (Both with the same daylight cameras and WBG-X thermal imager).

The commander had the PERI-RT 60 periscopic daysight (No dedicated thermal imager, just access to the gunners view).


While the vehicle was technically ready for mass production, the end of the Cold War (like so often) ultimately was the reason for the cancellation of the program.


The only existing prototype now is displayed at the WTS Koblenz. A disappointing end to a maybe overweight and simple, yet very powerful and (in contrast to Puma) maintainable machine.




I hope i was able to portrait it in an interesting manner, if there are still questions about the vehicle that i cannot answer, i can ask a curator at the WTS :)

Australia already has two nascent GVA so it will be a long time before we converge.

Sorry, I expected the Marder 2 to be well known to all posters. The others have provided plenty of informations, but here are the official specs from the old BWB website (the new website of the BAAINBw unfortunately lacks many details):

Hungarian Government confirms Lynx KF41 numbers: 218 vehicles, 172 built locally

We also agreed upon the place of the factory, near Zalaegerszeg (western part of the country). Additionally, it will include an R&D department too. The whole complex will create about 500 jobs, total cost will be around 168,000,000 EUR.

      Found a few higher resolution photographs from the recent North Korean military parade. We didn't have a topic for BEST KOREAN armored fighting vehicles, so here it is.
      New main battle tank, Abrams-Armata clone based on Ch'ŏnma turret design (welded, box-shaped turret) and Sŏn'gun hull design (i.e. centerline driver's position). The bolts of the armor on the hull front is finally visible given the increased resolution. It might not be ERA given the lack of lines inbetween. Maybe is a NERA module akin to the MEXAS hull add-on armor for the Leopard 2A5?
      Other details include an APS with four radar panels (the side-mounted radar panels look a lot different - and a lot more real - than the ones mounted at the turret corners) and twelve countermeasures in four banks (two banks à three launchers each at the turret front, two banks à three launchers on the left and right side of the turret). Thermal imagers for gunner and commander, meteorological mast, two laser warning receivers, 115 mm smoothbore gun without thermal sleeve but with muzze reference system, 30 mm grenade launcher on the turret, six smoke grenade dischargers (three at each turret rear corner)

      IMO the layout of the roof-mounted ERA is really odd. Either the armor array covering the left turret cheek is significantly thinner than the armor on the right turret cheek or the roof-mounted ERA overlaps with the armor.

      The first ERA/armor element of the skirt is connected by hinges and can probably swivel to allow better access to the track. There is a cut-out in the slat armor for the engine exhaust. Also note the actual turret ring - very small diameter compared to the outer dimensions of the turret.
      Stryker MGS copy with D-30 field gun clone and mid engine:

      Note there are four crew hatches. Driver (on the left front of the vehicle), commander (on the right front of the vehicle, seat is placed a bit further back), gunner (left side of the gun's overhead mount, next to the gunner's sight) and unknown crew member (right side of gun's overhead mount with 30 mm automatic grenade launcher mounted at the hatch). The vehicle also has a thermal imager and laser rangefinder (gunner's sight is identical to the new tank), but no independent optic for the commander. It also has the same meteorological mast and laser warner receivers as the new MBT.
      What is the purpose of the fourth crew member? He cannot realistically load the gun...
      The vehicle has a small trim vane for swimming, the side armor is made of very thin spaced steel that is bend on multiple spots, so it clearly is not ceramic armor as fitted to the actual Stryker.

      The tank destroyer variant of the same Stryker MGS copy fitted with a Bulsae-3 ATGM launcher.

      Note that there is again a third hatch with 30 mm automatic grenade launcher behind the commander's position. Laser warning receivers and trime vane are again stand-out features. The sighting complex for the Bulsae-3 ATGMs is different with a large circular optic (fitted with cover) probably being a thermal imager and two smaller lenses visible on the very right (as seen from the vehicle's point of view) probably containing a day sight and parts of the guidance system.

      Non line-of-sight ATGM carrier based on the 6x6 local variant of the BTR, again fitted with laser warning receivers and a trim vane. There are only two hatches and two windows, but there is a three men crew inside.
      There are a lot more photos here, but most of them are infantry of missile system (MLRS' and ICBMs).

      Disappeared for a long period, Mai_Waffentrager reappeared four months ago. 
      This time, he took out another photoshoped artifact. 

      He claimed that the Japanese prototype 105GSR (105 mm Gun Soft Recoil) used an autoloader similar to Swedish UDES 19 project. Then he showed this pic and said it came from a Japanese patent file. 
      Well, things turn out that it cames from Bofors AG's own patent, with all markings and numbers wiped out. 

      original file→https://patents.google.com/patent/GB1565069A/en?q=top+mounted+gun&assignee=bofors&oq=top+mounted+gun+bofors
      He has not changed since his Type 90 armor scam busted. Guys, stay sharp and be cautious.

      Backstory (skip if you don't like alternate history junk)
      The year is 2239. It has been roughly 210 years since the world was engulfed in nuclear war. Following the war, the United States splintered into hundreds of small statelets. While much knowledge was retained in some form (mostly through books and other printed media), the loss of population and destruction of industrial capability set back society immensely.
      Though the Pacific Northwest was less badly hit than other areas, the destruction of Seattle and Portland, coupled with the rupturing of the Cascadia Subduction Zone in 2043, caused society to regress to a mid-19th century technology level. However, in the early 2100s, the Cascade Republic formed, centered near Tacoma. The new nation grew rapidly, expanding to encompass most of Washington and Oregon by 2239. The Cascade Republic now extends from the Klamath River in the south to the Fraser River in the north, and from the Pacific roughly to central Idaho. Over time, the standard of living and industrial development improved (initially through salvaging of surviving equipment, by the late 2100s through new development); the population has grown to about 4.5 million (comparable to 1950 levels), and technology is at about a 1940 level. Automobiles are common, aircraft are less common, but not rare by any means. Computers are nonexistent aside from a few experimental devices; while scientists and engineers are aware of the principles behind microchips and other advanced electronics, the facilities to produce such components simply do not exist. Low rate production of early transistors recently restarted.
      The current armored force of the Cascade Republic consists of three armored brigades. They are presently equipped with domestically produced light tanks, dating to the 2190s. Weighing roughly 12 tons and armed with a 40mm gun, they represented the apex of the Cascade Republic's industrial capabilities at the time. And when they were built, they were sufficient for duties such as pacifying survivalist enclaves in remote areas. However, since that time, the geopolitical situation has complicated significantly. There are two main opponents the Cascade Republic's military could expect to face in the near future.
      The first is California. The state of California was hit particularly hard by the nuclear exchange. However, in 2160, several small polities in the southern part of the state near the ruins of Los Angeles unified. Adopting an ideology not unfamiliar to North Korea, the new state declared itself the successor to the legacy of California, and set about forcibly annexing the rest of the state. It took them less than 50 years to unite the rest of California, and spread into parts of Arizona and northern Mexico. While California's expansion stopped at the Klamath River for now, this is only due to poor supply lines and the desire to engage easier targets. (California's northward advanced did provide the final impetus for the last statelets in south Oregon to unify with the Cascade Republic voluntarily).
      California is heavily industrialized, possessing significant air, naval, and armored capabilities. Their technology level is comparable to the Cascade Republic's, but their superior industrial capabilities and population mean that they can produce larger vehicles in greater quantity than other countries. Intelligence shows they have vehicles weighing up to 50 tons with 3 inches of armor, though most of their tanks are much lighter.

      The expected frontlines for an engagement with the Californian military would be the coastal regions in southern Oregon. Advancing up the coastal roads would allow California to capture the most populated and industrialized regions of the Cascade Republic if they advanced far enough north. Fortunately, the terrain near the border is very difficult and favors the defender;

      (near the Californian border)

      The other opponent is Deseret, a Mormon theocratic state centered in Utah, and encompassing much of Nevada, western Colorado, and southern Idaho. Recently, tension has arisen with the Cascade Republic over two main issues. The first is the poorly defined border in Eastern Oregon / Northern Nevada; the old state boundary is virtually meaningless, and though the area is sparsely populated, it does represent a significant land area, with grazing and water resources. The more recent flashpoint is the Cascade Republic's recent annexation of Arco and the area to the east. Deseret historically regarded Idaho as being within its sphere of influence, and maintained several puppet states in the area (the largest being centered in Idaho Falls). They regard the annexation of a signficant (in terms of land area, not population) portion of Idaho as a major intrusion into their rightful territory. That the Cascade Republic has repaired the rail line leading to the old Naval Reactors Facility, and set up a significant military base there only makes the situation worse.
      Deseret's military is light and heavily focused on mobile operations. Though they are less heavily mechanized than the Cascade Republic's forces, operating mostly armored cars and cavalry, they still represent a significant threat  to supply and communication lines in the open terrain of eastern Oregon / southern Idaho.

      (a butte in the disputed region of Idaho, near Arco)
      As the head of a design team in the Cascade Republic military, you have been requested to design a new tank according to one of two specifications (or both if you so desire):
      Medium / Heavy Tank Weight: No more than 45 tons Width: No more than 10.8 feet (3.25 meters) Upper glacis / frontal turret armor of at least 3 in (76mm) LoS thickness Side armor at least 1in (25mm) thick (i.e. resistant to HMG fire) Power/weight ratio of at least 10 hp / ton No more than 6 crew members Primary armament capable of utilizing both anti-armor and high explosive rounds Light tank Weight: No more than 25 tons Width: No more than 10.8 feet Upper glacis / frontal turret armor of at least 1 in thickness Side armor of at least 3/8 in (10mm) thickness Power/weight ratio of at least 12 hp / ton No more than 6 crew members Primary armament capable of utilizing both anti-armor and high explosive rounds  
      Other relevant information:
      Any tank should be designed to operate against either of the Cascade Republic's likely opponents (California or Deseret) The primary heavy machine gun is the M2, the primary medium machine gun is the M240. Use of one or both of these as coaxial and/or secondary armament is encouraged. The secret archives of the Cascade Republic are available for your use. Sadly, there are no running prewar armored vehicles, the best are some rusted hulks that have long been stripped of usable equipment. (Lima Tank Plant ate a 500 kt ground burst) Both HEAT and APFSDS rounds are in testing. APCR is the primary anti-armor round of the Cascade Republic. Either diesel or gasoline engines are acceptable, the Cascade Republic is friendly with oil producing regions in Canada (OOC: Engines are at about a late 1940s/early 50s tech level) The adaptability of the tank to other variants (such as SPAA, SPG, recovery vehicle, etc.) is preferred but not the primary metric that will be used to decide on a design. Ease of maintenance in the field is highly important. Any designs produced will be compared against the M4 Sherman and M3 Stuart (for medium/heavy and light tank), as these blueprints are readily available, and these tanks are well within the Cascade Republic's manufacturing capabilities.
