and ? during 1966 test IIRC brits noted the tendency of L1 to swing when moving at high speed over rough terrain, movement on roads with maximum speed was possible only within half an hour due to the risk of overheating rubber bondage of roadwheels  at a speed of 50 km / h, overheating occurred an hour later, and to continue the movement it was required to drop the speed to 40 km / h

 

 

 

 

Apparently the Germans did consider this a problem.  The Leopard 1 has rubber cladding on the inner side of the track links.

 

Leo 2 does not.

Only by 1:55 they started showing actually relevant capabilities.

In demonstrations #1 and #2, firing a buttload of rounds, especially when the ammo belly is already quite ridiculously low (180, although hopefully it's only 1 magazine and there are more available rounds inside the vehicle), is stupid when first round hit accuracy is that good.

In demonstration #3 it should have been done whilst on the move because the first thing such vehicle's crew should be doing when seeing an MBT or IFV (note the Skyranger has HE-F based rounds, not APFSDS, unless it has some sort of dual feed) is flee for cover. 

Demonstration #4 was actually much more practical. 2 rounds on a maneuvering drone at good range is what you need. Much more ammo-efficient, much more difficult for enemies to get a location on you, and actually gets the job done without throwing the gun meters off target.

 

Overall, though, I'm not really impressed. The defense sector in the US and Israel (and I assume any country that cooperated) has already demonstrated the feasibility of a 100kW laser atop a reasonably sized platform. Even in adverse weather, such high powered laser should be very capable in the low ranges the Skyranger is expected to operate.

Next up is the usage of missiles - nowadays it's an absolute must. Turn it into a proper SHORAD instead of a C-RAM or VSHORAD style weapon system, and it could be made into a single system capable of doing point defense for long range air defenses and the required numbers for the protection of a brigade-sized formation can go down.

The gun is designed to shoot down fast-moving aircraft, mortar rounds and cruise missiles at a longer distance (up to 3.5 kilometres against fast targets, 5 km against slow-flying targets), the test area however limited the maximum range to 1-2 km. That's why it looks like an overkill, because at this distance and the low velocity of the targets, it is indeed an overkill. There are 200 rounds ready to fire, enough for approximately 20 engagements of aircraft or munitions (between 18 to 24 rounds should be fired against jets to maximize the kill probability) - that is not that far off from other self-propelled anti-air guns. The Gepard had 2 x 320 rounds of 35 x 228 mm APHE (and later FAPDS), but could engage only 25 fast-flying aircrafts due to the lower kill probability of dumb rounds. Rheinmetall demonstrated three different types of AHEAD/KETF rounds, fine-tuned to defeat different threats (i.e. the size and amount of tungsten sub-projectiles differed).

That is nothing special. Rheinmetall demonstrated high energy lasers (including the HEL on Wheels based on the Boxer) five years ago, also in Switzerland.

A 100 kW laser might sound nice, but it is not practical for armored fighting vehicles; the power supply is limited and there isn't enough space to fit a larger generator into a Boxer (or any other AFV for that matter). That is why realistically the size of lasers for AFVs is limited to 5-30 kW at most, which impacts performance and range. If you've seen footage of such lasers being tested against drones or other targets, you should know that they are short-ranged (a 100 kW laser has an effective range of about 10 km, a 5-30 kW laser has a much shorter range) and require quite a bit of time (multiple seconds) to defeat a drone; Rheinmetall named 3 km as effective range against mortars (for a 30 kW laser). That limits the usefulness of HEL (high energy lasers) quite a bit. The laser integrated onto a Stryker for the US Army has an output of just 5 kW!

 

On naval vessels, where space and energy allow integrating larger lasers, they make sense. For AFVs they are not efficient enough.

There just isn't enough space to have a 35 mm gun and missiles in a single vehicle, unless you meant something like taping a few MANPADS to the gun barrel. There will be dedicated Boxers with surface-to-air missiles (at least that has been proposed by various companies); either IRIS-T-SL or NASAMS or Mistral-3.

"Ready Now"
haha sure.
After the development Hell the Puma went through i would say it would only be ready after the S1 and S2 upgrades and then some.
For me the Lynx looks too clean for being ready.
Like how do you get ontop of and not slip and break your neck and where do you stow your shit?
And i only can imagine the problems they will have with the thing.
The Puma already has some mind-boggling bugs.

 

But maybe Rheinmetall did a good job. Who knows.

Also what could Raytheon contribute to the thing?
Doesnt Raytheon do the M113 on Steroids?

Having been inside the KF41 - it is a napkinpanzer. It is 100% a concept demonstrator. There is *a lot* of work required to get that (well travelled) single prototype anywhere near usable. Look in the back, for a start:

Don't forget that the TH-301 was basically an improvement of their work for TAM. I don't understand the sudden IFV-cum-Tank fetish. (I understand the money, and the idea of TDs... but trying to replace the MBT with a lightly armored vehicle will end in pain)

Looks like the one that ended up at APG. Note the nick in the mantlet and the damaged gun (shorter than it should be, presumably destroyed by the crew by firing with the buffer and recuperator oil drained)

Do you know if the 35 ton stripped weight for the Lynx mentioned in that Breaking Defense article would include a 'mission module'?

 

Unfortunately I don't know. In general 35 short tons (31.75 tonnes) isn't meant to be a weight class covered by the KF41 variant, but the smaller Lynx KF31. At this weight class, other IFVs like the Puma IFV (with armor kit for the protection class "A") can be fully functional. The Lynx KF41 however is quite a bit bigger than the Puma and seems to make use of less weight reduction measures. Maybe it is possible to have a KF41 with mission module and a weight of 35 short tons, but that would most likely require to remove all/most armor modules.

      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.
