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


Recommended Posts

Lots of good stuff there, @SH_MM, which has helped join some dots for me. I appreciate you taking the time to write such a detailed post. 
 

Regarding the Australian Boxer purchase, the customer has differentiated between “Block 1” and “Block 2” deliveries. The first 25 vehicles to be delivered (two delivered to date) are the Block 1 standard, with an interim configuration Lance turret. The first turreted Block 1 vehicle is due to be delivered around September this year. The exact configuration of the Lance turret for the Block 2 is yet to be determined, & will likely be informed by the IFV phase of the project (L400-3). 
 

Tree strike is a thing in Australia. Generally the first thing added or beefed up on a vehicle in Australian service are brush guards or deflectors. The Block 1 Boxers are a good demonstration of this - look at the side stowage racks. Shaped & angled brush deflectors to protect the side stowage & the side situational awareness cameras from being scrubbed (ha!) off the side of the truck. 
 

The launcher on the Risk Mitigation Activity (RMA - trial) overhung the side of the vehicle (Boxer). On Puma, the launcher was inside the outer mould line of the vehicle. On Boxer, the overhang means that, with the turret at 12 o’clock, the launcher could be the first thing that hits a tree as the vehicle threads through wooded terrain. Anything that lowers the exposure of the launcher is worth serious configuration, especially with the launcher mounted on the opposite side of the vehicle To the driver. Compare that to Bradley. Lower profile launcher on the same side as the driver, so that it’s easier to avoid tree strike. 
 

Regarding damping and Spike-LR2, one issue identified has been the lifecycle of the missile. Currently, as soon as the missile is loaded into the launcher, it has to either be fired, or if at the conclusion of the activity it has not, it has to be repackaged and returned to the factory for refurbishment. The useable life of the missile in the launcher is sensitive information, but it is finite before being declared unserviceable. The longer a missile is carried in a launcher, the lower its pH. In live-fire exercises, this isn’t an issue. Unpack, load, aim, fire. But operational use is different. 
 

Improving damping takes many forms. Taking weight out of the launcher is one way. Either way, improving damping is intended to improve the service life of the missile once loaded into the launcher and retain a high pH (& probability of correct function). It’s my understanding that one of the design goals of the new launcher is to extend the useful life of Spike LR2.

Supacat RAMP

SupaSHOCK not SupaCAT :)  Constant problem getting these name typos.  Both involved with L400.  Key difference is that SupaSHOCk is 49% owned by Rheinmetall.

 

Per 2085662 - yep, tree strike is a thing.  Moving through Australian scrub involves constant contact with trees and branches of various sizes.  One of the reasons why the SAAB Barracuda stuff is a waste of money here.  It just gets ripped off and randomly scattered all over the bush.

 

Last I heard (Feb 2020), LANCE 2.0 does not have mission pods - its configured more like a conventional crewed turret.  The SPIKE launcher is inside the outer armoured shell of the complete turret.

Reaching a protection level similar to the Leopard 1A1A1 ?

 

Yes, but why? I find this whole perforated plates experiment with Leopard and other stuff totally useless.

 

Rjpz was already immune vs 23-30mm, and already hopeless against anything bigger. With add on armor, the only weapon against this might have worked, is the D-56T of the PT-76.

For Leopard-1, the extra armor reduced vulnerability against 100mm APHE (according to german documents), but honestly, it was waaaaay too late. In 1974, even the 3BM8 APDS was being replaced by 3BM20 APFSDS. 1-2 years later production of the even more powerful 3BM25 began. 

Yes, some less well equipped WP armies retained BR-412B (like Hungary), but even these armies had access to 3BM8.

Perhaps it was an effort in increasing protection against 152mm/155mm fragments at closer impact ranges?

30mm of base front is more than enough, side armour addons don't know how thick

KMW details new Boxer Leguan bridging module

vu8xagn.png
kV5IigW.png
This Drive Module doesn't have a visible exhaust. A3 feature?
 

Quote

Krauss-Maffei Wegmann (KMW) has developed an internally funded mission module for the ARTEC Boxer 8×8 Multi-Role Armoured Vehicle (MRAV), which can rapidly launch and recover a Leguan 14 m or a Leguan-compatible 22 m bridge over wet and dry gaps.
 

The baseline Leguan bridge has been built in large numbers and can be launched from a variety of platforms, including the Leopard 1 or Leopard 2 main battle tanks (MBTs) as well as other tracked and wheeled platforms.
 

According to KMW, by mid-2020 total sales of the Leguan bridge system amounted to 244 tracked systems, 45 wheeled, 483 bridges, and seven ferry and floating kits.
 

Gerhard Greifenegger, the company’s executive manager for Military Mobile Bridges, told Janes: “With the bridge Boxer and its unique rear launching concept, we realise a maximum bridge length, available on a highly protected and highly mobile platform.”


The new Leguan Boxer mission module is a direct replacement for the standard Boxer mission module, which is typically used in the armoured personnel carrier (APC) role with seats for 10 dismounts.
 

In this role, Boxer can transport and launch a one-piece 14 m Leguan bridge that can span up to a 13 m gap and handle military load class (MLC) 80, or MLC 100.

Did they actually fire them that way, or are they just carrying them?

From what I remember of the thing, it should just be carrying them.  The vehicle was used as a transport for tank hunters and their weapons, not as some tank destroyer itself.

So, according to ES&T, the Bundeswehr is losing patience with the Puma and are considering replacing the entire fleet if the operational readiness is not proven in the coming year.

 

As for what might replace it, BAE Systems Hägglunds should appreciate this part of the article:

“In briefings of the Army Command, the CV90 has so far been mentioned as an alternative and favorite. But the Lynx would certainly be a candidate as well, as it has the DNA of the puma and at the same time learned the lessons from the problems of the puma in the Bundeswehr.”

 

I remain unconvinced, however, that this is something that could actually happen. With 330+ vehicles already delivered, the Bundeswehr is almost certainly way too deep in the Puma project to get rid of them simply because they fail to meet a readiness goal in the coming year(s).

 

@SH_MM care to take a jab at this one?

I think the aim is to put KMW under pressure. But it is very clear that Lynx/CV90 are no real options.

 

~400 Puma with ~10M€ each + development cost + spare parts means maybe around 5 billion € wasted with some more 3.5 to be spent for CV90s.

 

They will pay another billion to remove the most common child sicknesses and live with what is left.

It is a more controversial article. While ESuT publishes some very interesting and well written articles, sometimes they also rely on less accurate sources and rumors. E.g. the unit that supposedly complained about the lackluster reliability of the Puma doesn't actually operate it yet...

 

The Marder lifetime extension has been approved and - after new engines already have been ordered - the Bundestag approved the purchase and installation of new ATTICA-GM thermal imagers this week. While I personally wouldn't dislike a two systems solutions, the CV90 seems to be rather unsuited for the German Army based on several factors (it would hardly solve any of the Puma's real problems like the reduced carry capacity and restricted interior height and in ~2002 it was deemed impossible to modify the ASCOD's and CV90's designs in such a way that they could meet the protection criteria, which lead to the creation of the Puma IFV), but only act as an expensive shortcut to negate some of the teething problems. A new firmware is already being rolled out which is supposed to eliminate/limit the software issues.

 

The idea that the CV90 would be favored in Germany falls into the same category as ESuT announcing that the Wiesel 1 might be fitted with a 27 mm revolver gun or that LANCE turret already had been selected for the heavy fire support  variant of the Boxer - i.e. they are just speculations and indiviual opinions.

@Laser Shark I am not sure about this article. Its true that there is a parallel effort with the Marder Upgrade and the Puma for the VJTF.
But the technical verification was already successful for the VJTF Puma.
 


LtCol Feilcke Head of Field tests at the Bureau for Army Development:
"Depending on the result of the verification of the AFV Puma VJTF, it was also decided to commission a second batch, which is to be introduced in a design level S1 from 2023. The inflow of the 2nd batch is coordinated with the planned, consolidated retrofit planning in order to keep the availability in the troops as constant as possible and to compensate for the commitment of the large equipment in the conversion measure S1."

I am quite confused with the difference of "Nachweisführung"/Verification and "Einsatzprüfung"/Field test and if it was already successful or if it is the "Einsatzprüfung" that needs to be successful.

There is positive feedback but also still some negative points, which i dont know in detail.
And the field test is still running.

On the CV90:
There was already a decision in 2019 between second batch of Pumas, Upgraded Marders and Boxers with 30mm Turrets:
"For the task-oriented features of the armored infantry troops with armored personnel carriers three possibilities of action were studied. Including the hiring of additional SPz Puma, another life extension including combat efficiency of Marder and the procurement of armored transport vehicle (GTK) Boxer fell into a SPz version. In addition to assessing the associated quantity structures, costs and expenses, the army has expressed the tactical-operational reasons for the procurement of additional SPz Puma. "

So again maybe things changed, maybe they are putting pressure on PSM, maybe someone wants another option they can quickly disregard.

On ESuT:
I would always judge depending on the Author.
There are alot of different ones. From Industry Marketing people to Heads of Departments in the Army itself.
So always look at the end of the page for who the Author actually is.

I think ESuT is probably right but is probably just reporting on the Options that are just there to be disregarded or just to have a comparison.

And yes there wasnt any news of 391 or 371 receiving Pumas compared to every other time when a Bataillon received Pumas.
Also it would be weird that a Bataillon would use two different IFVs simultaneusly. Just think about the space for all those IFVs and the training.

Is there an puplic overview about the key issues?

 

To list a few of the problems connected to low availability for the Puma:

 

- Lack of purchasement of spare parts (with initial spare part kits for some units only bought this(!) year)

- Same thing applies to the special tools needed to maintain the vehicle

- Faulty software, leading to the crew having to reboot the entire system. 

- Different versions of certain parts and software being used for production vehicles

- Not enough trained maintenance personel who have been retrained to work on the Puma

 

The main issue of the entire program, which basically is the root for all these re-occuring problelms, is that the political side really pressed down on the price, resulting in a lower amount of vehicles, which raised prices even more.

This led to a huge cut in procurement and organisation on the logistics end to save costs in order to buy enough vehicles.

As we can all see this has backfired really badly.

Well, that is basically what I have read and heared at different scources as well.

That is why I can't understand why Puma is around in the media everywhere because that are all customer failures (except software).

If almost all failure are on my side I wouldn't think about a replacement..

      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.

      Requirements
       
      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.
