Introduction

Not often do we see such Pakistani modifications for ground vehicles apart from the more well known Al-Zarrar MBT.
Todays hero however, is know by just one, maybe two photographs at max. As can be seen from its only photograph, it is named “BATTAR”, meaning cutter, named after a sword owned by the Prophet Muhammad (PBUH).
This APC was and still is in Pakistan Armed Forces service since around 1989 when Pakistan started imports and licensed production of the M113.

There is not much to say about this other than that this is a unique modification of the M113 and M40 recoilless rifles made by Pakistan Ordinance Factories (POF) and was not kept in service for long.
Contrary to my previous belief, the BATTAR does not come equipped with the M8C machine gun for ranging. Instead, according to a source, it has an integrated Laser rangefinder in the twin M40A1 mount to allow for accurate ranging shots in place of the machine gun, whether against infantry or armoured vehicles.

The M113 APC has a history of being adapted by armies all around the world to suit their various purposes and Pakistan has utilised many a variant of this venerable workhorse. Be they armed with Heavy machine guns, light machine guns, Anti tank missiles, Surface to air missiles and cannons or recoilless rifles.
The M113 is currently still in service with the Pakistan armed forces to this day.
This vehicle has also been called the M113 Mk/1 in Pakistani service.
Something interesting about this vehicle though, which cannot really be seen from the poor picture quality is the following:

Pakistan Ordnance Factories have also developed a twin 106 mm recoilless rifle mount which, for trials purposes, has been fitted onto an M113A1 APC of the Pakistani Army. The system also integrates a laser rangefinder into the existing sight of the 106 mm recoilless rifle to replace the elbow telescope. This allows the range to be displayed for the gunner in the sighting optic, which means that he can apply the superelevation and fire without having to look at another instrument. The effective range of the recoilless rifles is 1,500 m. The locally produced vehicle is called the M113A2 Mk-1 in Pakistan Army service and is almost identical to the US M113 except that the 12.7 mm M2 machine gun has been replaced by a 12.7 mm Type 59 machine gun manufactured by Pakistan Ordnance factories.

Upon closer inspection, the number inside the yellow circle is 12 on both vehicles and the number in white following the arrow is 078927 on the black-white photo and 078902 on the coloured photo.
This does prove that they are NOT the same vehicle. I am unsure if the one in the coloured photograph is Pakistani (it does have a Pakistan Defence forum watermark though) but regardless, we now have two slightly different models.

ладно с этим разобрались, а это что за тевтонский гений сделал…

Leopard 2 140 (T19)

German prototype Leopard 2 turret on a Leopard 1 hull. The Versuchsträger Mit Turm T19. From what I have been able to find it was a modified 2AV turret used as a testbed for a bustle auto loader. The 120mm gun is missing the thermal sleeve and fume extractor.

Running model of the test vehicle with the T 19 (Leopard 2 AV) turret, in which the Rheinmetall / Wegmann & Co automatic loader was installed for dynamic testing in 1983.

KWS I focused on the installation of a 120mm L/55 gun and the use of new, advanced ammunition (with muzzle velocity of up to 1800 m/s)
KWS II focused on additional armour (both turret and hull), crew protection systems and advanced battlefield electronics
KWS III focused on the then-developed 140mm gun to replace the 120mm Rheinmetall smoothbore and the integration of the IFIS system from the Leopard 2 IVT phase

Gepard 1A2 EOTS III Prototype upgrade

New glasses eh? 😎

EOTS, standing for Electro-Optical-Targeting-System is a modern TV+IR combat optic system made by Hensoldt Optronics. The most modern IFV, the Puma, currently in service with the Bundeswehr, uses the EOTS optics for its FCS. During experimentation to modernise the Gepard SPAAG, the EOTS was integrated onto the roof of a Gepard to give it IR target detection, tracking and engagement capabilities.

(Refer to the attached ‘brochure’ for the features of the EOTS III)

The very same brochure, gives us a sneak peek of the integration of the modern optics onto a Gepard 1A2 SPAAG.

And another source, a video, shows us the EOTS on the Gepard working in the trials and testing phase. The video shows a Gepard tracking a Banshee drone’s IR signature with the EOTS optics. This takes place during the KMW trials in 2008 at ADA Life Firing Range in Todendorf/Germany.

Video of the EOTS on the Gepard 1A2

https://youtu.be/ax2HOYHKKMI

The drone was destroyed by a neighbouring weapon system, possibly an Ozelot, with a FIM-92 Stinger missile at a distance of about round about 5300 meters from the Gepard that is tracking the drone (“ENTF” = Distance).

VAK 191B

history header

Introduction

Propulsion

The propulsion was provided by a Rolls-Royce/MTU RB.193-12 swivel jet engine and two Rolls-Royce RB.162-81 lift engines. The RB.193 lift/cruise engine was a two-shaft turbofan similar to the Bristol Siddeley Pegasus of the Kestrel/Harrier. It had four rotating side nozzles, which were adjusted by a Plessey pneumatic motor via cardan shafts and chains over a swivel range of 95 degrees. The air intake was optimized for cruising at Mach 0.92, but offered an additional opening for hovering and slow flight thanks to a movable front section. The two RB.162-81 lift engines were installed at a rearward incline of 12.5 degrees. In later versions, their jets were to be deflected by fuselage flaps.

Thrust and lift

The designers were convinced that this division between lift/thrust and lift engines represented the best compromise between the required take-off power and economical fuel consumption in high-speed flight. In terms of their arrangement, they offered positive ground effects, at least compared to a design with separate lift and thrust engines.

For control and stabilization in hover and transition flight, air was taken from all engines and blown out separately via a redundant pipe system at the wing tips and at the fuselage nose and tail to generate torque. The air nozzles required for this were directly connected to the rudders.

Control

The control torques in the pitch axis were further increased by modulating the thrusts of the two lift engines. In the event of a lift engine failure, the automatic flight control system would have taken over control of the remaining lift thrust and kept the aircraft in a horizontal position to enable the pilot to eject using the Martin Baker Mk 9 ejection seat in a normal flight attitude.

The pilot’s commands on the VAK 191 B were not transmitted mechanically to the rudder servo motors, but electrically, with triple redundancy using a flight controller - known today as fly-by-wire. In the event of a total failure of the electrical flight control, the rudder servo motors could still be controlled mechanically by automatically closing a clutch. The high-pressure hydraulic system worked at 4000 psi, a value that is rarely achieved even today.

Due to the requirement With regard to the range at transonic cruising speeds close to the ground, particular attention was paid during the design to ensuring that the pilot should only be exposed to a tolerable level of acceleration in gusty weather. For this purpose, wings with a high wing loading, a small aspect ratio and a relatively large leading edge sweep were chosen, which were arranged in a high position due to the central position of the swivel jet engine and had a negative V position.

To reduce the conventional landing speed and to shorten the transition distances, the wing was equipped with trailing edge camber flaps. In addition, the ailerons could be deflected downwards in the same direction. The landing gear, fitted with low-pressure tires, had brakes in the nose and main gear and nose wheel steering. A braking parachute was provided to shorten the roll-out distance during a horizontal landing.

Compared to Harrier

Previously called the FW 1262

The VAK 191 B V2 is now in the Defense Technology Study Collection in Koblenz.

Armament

The cargo area under the main engine was four meters long, 88 cm wide and 60 cm high. It was to be equipped with equipment sets pre-loaded on the ground. The early brochures of the Vereinigte Flugtechnische Werke list armament alternatives such as:

2 x 450 kg bombs plus 115 kg equipment
4 x 225 kg bombs
2 extendable rocket launchers, each with 54 x 70mm rockets.

Camera systems or on-board cannons and a 1700 l tank were also conceivable. Ultimately, however, an extensive on-board measuring and telemetry system was installed here, which made it possible to record, process, save and transmit the data generated during testing to a ground station. Of the total of 450 possible measured values, 260 could be recorded simultaneously on PCM and FM channels.

Other armament options include:

2 x Kormoran Anti ship missiles

Leopard 3 (VT-1-1)

The Cold War JagdTiger

Leo 3 program

many tanks have been put up for the leopard 3 title, even the KF-51 Panther, whether officially by the companies or by news outlets, calling many a tank the successor of the famed leopard 2, but as of now, no one solution has taken the name for sure. hopes lie on the MGCS for now. lets see what becomes of that, however, lets introduce a competitor who lost the title for Leopard 3.

text from post 0

The tank, which was supposed to replace the Leopard 2. The tank had two versions - VT-1-1 (photo 3-4) (with two 105mm guns) and VT-1-2 (photo 1-2) (with two 120mm guns), and the VT-1-1 had both barrels automatically loaded, while the VT-1-2 had one gun loaded manually. The tanks also differed in engine power - the VT-1-1 had a 2000 hp engine, and the VT-1-2 had a 2200 hp engine.

text from post 1

Today we will talk about completely perverted German fantasies, namely about the VT1-1 and VT1-2 tanks, or as they were also called “Leopard 3” (not to be confused with the future MBT). It was in the early 70s, with the MBT-70 project things somehow did not work out right away, they did not share the gun, engine and other units. But a new main battle tank was still needed. And it was very necessary, since tankers somehow did not particularly show a desire to fight on spotted cats 1 against the new-fangled Soviet T-64. All Western military personnel were shocked by the sixty-fours.

As a result, the Germans continued working on a new tank with a standard layout. But there were some particularly clever ones, like engineer Wolfgang Matos, who headed his own project for a new tank. He considered the standard layout to be obsolete and did not particularly believe in the prospects of the Leopard being developed in a neighboring project. As a result, they developed a new tank with a turretless layout. And apparently they thought then that one gun is good, but two are better. Therefore, they stuffed two guns into both prototypes, on the left and right sides of the vehicle. The guns were aimed vertically using a drive, and horizontally by turning the hull. At a range of 1.5 km, the axes of the guns intersected.

The first prototype VT1-1 was equipped with two well-known English L7 guns. Each gun was equipped with an automatic loading system, a trend of the time, and still cool today. The second prototype VT1-2 was even more terrifying: it carried two 120mm Rh 120 guns, one with automatic loading, the second with manual, because the gloomy genius was unable to make a mirror copy of the AZ. Both vehicles were equipped with a PERI R12 sight, which was borrowed from a neighboring project. When firing while standing, the vehicle showed better results compared to turret tanks. But firing on the move became a problem, although this was clear even at the sketch stage. The tank could not aim normally on the move in the horizontal plane, when firing, the vehicle rocked and skidded strongly, the trajectory of movement changed, it was difficult for the driver to control the equipment in such conditions.

In terms of mobility, everything was fine. The vehicles inherited the chassis from the KPz-70 with hydropneumatic suspension, but the hull was shortened and one support roller was removed. A 1,500-horsepower engine was used as a power plant, yes, again taken from a neighboring project. The engine was initially boosted to 2,000 hp and installed on the VT1-1. And on the VT1-2 it was boosted even more, reaching a power of 2,200 hp. The mass of the vehicle was 38-40 tons, which, combined with such powerful engines, gave an incredible 53 hp/t. Modern MBTs, and what’s more, even light tanks smoke on the sidelines. Therefore, the vehicle was very mobile.

The crew consisted of 3 people: commander, gunner and driver. The driver was located in the center at the front of the hull. Behind him were the commander and gunner, to the left of the tank’s axis. The armor was not seriously considered, the Germans still believed that “barnya nenadka!” and relied on firepower and mobility, let me remind you, 2 guns with an automatic loader and 53 horses per ton. Experimental models were made of regular steel, not armored steel, which saved weight. A real tank would have weighed 2-4 tons more. After a lull, in the 80s the project was revisited and several more GVT prototypes were made, on which the guns were moved closer to the center and the internal layout was changed, on some variants the chassis was lengthened.

From 1972 to 1976, the VT1 underwent a test cycle. During this time, they drove many kilometers, fired a lot of shots, etc. As a result, it was impossible to shoot normally on the move, the layout was strange, the neighboring project showed good results. Later, the spotted cat two was born, and the military came to the conclusion that why the hell do we need this, it is better to modernize the Leopard 2. Therefore, the Leopard 3 project was abandoned. In the 80s, they returned to the project again, tested the GVT and eventually closed the project completely and decided to improve the Leopard 2, and thank God. But the double-barreled tank was developed as a promising replacement for the Leopard 2.

text from post 2

Experimental two-gun tank VT1

In the early 1970s, the MaK (Maschinenbau Kiel) company began to consider the prospects of modern tanks on its own initiative. It was assumed that the vehicle being developed, designated VT1 (German: Versuchstrager 1 - test model), would be ready by the time its “peer” Leopard 2 began to become obsolete.

During the analysis of the existing designs, MaK analysts and engineers came to the conclusion that the existing tank layout with a rotating turret and only one gun was no longer capable of providing the necessary firepower. In addition, the success of the Swedish turretless Strv 103 tank, which managed to combine sufficient firepower (105-mm gun) with good performance, maneuverability and protection, had an effect.

True, the rigid fastening of the gun required a significantly more complicated suspension: vertical aiming was carried out by skewing the entire hull. German engineers decided to adopt the idea of a tank without a turret, but at the same time not to be clever with the aiming of the gun. At the same time, a group of engineers led by Wolfgang Matos came to the conclusion that it was necessary to install two guns on the prospective tank at once. According to the designers, it was not possible to achieve a significant increase in combat qualities by other means.

The experimental MBT-70 tank was chosen as the basis for the new experimental design. This armored vehicle was not suitable for serial production, but was attractive for use in experimental work on the VT1 topic. In accordance with the turretless layout of the future tank, the chassis was shortened, due to which instead of six road wheels per side there were only five.

The hydropneumatic suspension was modified accordingly. The MBT-70 tank’s native Continental AVCR-1100-3 diesel engine was replaced by an MB 873 Ra-500 diesel engine. The new engine could operate continuously, producing one and a half thousand horsepower, and “accelerate” to 2175 hp in a short time.

At the same time, in emergency mode, the 38-ton tank had a specific power of over 50 hp per ton of weight. This is approximately twice as high as most modern tanks. One of the reasons for the high specific power was the comparatively low weight of the structure. Given the experimental nature of the project, MaK engineers made experimental tanks not from special armor steel, but from lighter “regular” grades. In this way, about 2-4 tons of weight were saved. An armored cabin was installed on the modified chassis of the MBT-70 tank. It is noteworthy that with a comparatively large internal volume, it did not have very large dimensions. The overall height of the VT1 was slightly more than two meters, which was more than 80 centimeters less than the original MBT-70.

In 1972, the assembly of the first prototypes of the VT1-1 tank was completed. The first example was equipped with two 105-mm rifled L7 guns. Both guns had automatic loaders.

The VT1-2 tank, in turn, received 120-mm smoothbore Rh-120 guns. However, only one gun was equipped with an automatic loader. The fact is that during the development of the new tank, the designers of Maschinenbau Kiel were unable to produce a mirror version of this unit. Therefore, one gun was loaded automatically, and the second was fed shells and cartridges by the crew manually. The design of the gun mounts on the VT1-1 and VT1-2 tanks is interesting. On both vehicles, the guns had the ability to only aim vertically. The guns did not move horizontally. In addition, they were installed with a small convergence angle: the aiming lines intersected at a distance of 1,500 meters.

Testing of the two prototypes continued until 1976. During this time, the tanks traveled thousands of kilometers across the testing ground and fired hundreds of shots. First of all, it became clear that the VT1-1, due to its very concept, was not capable of firing more or less accurately on the move. When firing from one gun, the recoil slightly turned the tank around the vertical axis, which had to be countered by turning the entire tank. This problem was only aggravated by the lack of sighting devices for the driver.

Only the commander and gunner had Carl Zeiss PERI R12 periscope sights. Naturally, in combination with the lack of horizontal aiming of the guns, this greatly complicated firing. In addition, the design strength limitations did not allow both guns to be fired simultaneously. Thus, the only way to somehow eliminate the tank turning during firing was “prohibited” by the design itself. It is noteworthy that on the above-mentioned Swedish Strv 103 tank, aiming was carried out by the driver. For this purpose, he had a sight and controls for the hull tilt.
