#Ukraine/#Russia πŸ‡ΊπŸ‡¦πŸ‡·πŸ‡Ί:

Since 2014, there have been many vehicle modifications on both sides on the #Ukrainian battlefield. One of the most frequently modified vehicles is the MT-LB, originally intended as an artillery tractor.

Of course, many mass-produced vehicles were built on the MT-LB chassis, such as the 9k35 Strela-10, the 9P149 Shturm-S, or the 2S1 Gvozdika.

2/ Strela-10Shturm-S2S1 Gvozdika
Since the beginning of the war in #Donbas, soldiers have been forced to use the MT-LB for tasks other than those for which it was intended. They used it, and still do, for example as an APC. They immediately began to feel the weakness of the vehicle's firepower and armour.

3/ Image
So the soldiers began to modify their MT-LBs. They welded on additional armor and increased firepower. The πŸ‡ΊπŸ‡¦#Ukrainian army itself attempted to increase firepower by adding a 12.7mm DshKM machine gun in the armoured turret. That’s how MT-LB-AT was born.

4/ ImageImage
However, this modification was only in very limited numbers, so field modifications were created. The easiest way was to weld Slat armor, additional armor and machine gun on the vehicle.

5/ ImageImage
On this particular MT-LB, the soldiers welded on additional armor, Slat armor, and a pair of 14.5mm KPVT machine guns. The gunner operated the machine guns manually and was protected by the welded armor.

6/ ImageImageImage
#LPR/#DPR fitted this MT-LB with a 12.7mm DShKM machine gun and welded on a couple of plates.

7/ Image
The separatists also fitted several MT-LBs with mounts for the RPO-A Shmel thermobaric warhead rocket launcher’s.

8/ ImageImage
#Ukrainian MT-LB was also seen with #Turkish Aselsan 'Serdar' RCWS which features an NSVT and PK machine guns and can also carry two Skif ATGMs.

The turret was probably a demonstrator and after the outbreak of war it was fitted to the first vehicle they found.

9/
However, more complex modifications began to appear. Several MT-LBs were built for the Dnepr-1 battalion with a raised superstructure, slat armor and a turret with a 14.5mm KPVT machine gun from a BTR-60.

Several similar MT-LBs with BTR-60 turrets also served in Azov.

10/ ImageImageImage
Another monstrosity. A cut off part of BRDM-2 with BPU-1 turret and welded on MT-LB. First seen during summer 2022 in UAF service.

11/ Image
Another popular modification is to mount the 23mm ZU-23-2 on the superstructure. Many of these vehicles have been built and operated by both sides.

The photos show the cannons mounted on captured Russian MT-LBVM(K)’s.

12/ ImageImage
The #LNR/#LPR even operated at least two MT-LBs that had a turret made from decommissioned BMP-1 IFVs.

13/ Image
There were also a few "self-propelled mortars", where an automatic 82mm 2B9 Vasilek mortar was added to the MT-LB superstructure. They were sometimes mounted in their own turret as well. They were manually operated, and some pieces could be operated from the inside.

14/ ImageImageImageImage
At least one MT-LB was fitted with a turret from a 2S9 Nona by the #separatists, creating an interesting improvised self-propelled mortar.

15/ ImageImage
This is a very interesting modification. In 2015, the #Ukrainians modified the decommissioned Strela-10s by mounting two B-8 rocket pods firing 80mm S-8 rockets instead of anti-air missiles. These improvised MLRS were intended to shell an area rather than specific targets.

16/ ImageImageImageImage
Another improvised MLRS, with #Ukrainian soldiers creating their own version of the Soviet Grad-1. Both vehicles were on MT-LB chassis and used Grad rocket launchers. They can be distinguished by the fact that the Ukrainian modification has all 40 tubes, the Grad-1 "only" 36

A 2022 modification in which a MT-12 Rapira 100 mm anti-tank gun was mounted on top of the vehicle with an open-topped superstructure for cover. This modification is called MT-LB-12.

18/ ImageImageImage
Earth is full of states and factions using MT-LB and its versions. Some mass produced, some improvised. For example Armenian MT-LB with S-60 cannon, Bulgarian BMP-23 IFV, Russian MT-LBM 6MB prototype etc.

If you made it this far, thank you for reading.

I'll be glad for the RT too.

Special thanks to @BuschModelar for some photos and informations!

πŸ‡¨πŸ‡Ώ#Czechia: News from the Czech defence industry, specifically STV Group (@stv_group).

🧡[THREAD, 1/4]Image
1) Ammunition production (I already touched on this topic in a recent thread about the Czech artillery regiment, link below at the end of the thread).

STV Group will complete a new artillery ammunition production line by the end of this year, which will increase production capacity by 100,000 artillery shells per year. At least one more production line will be built next year, so the production of artillery ammunition should reach at least 300,000 shells per year. Together with other large-calibre ammunition, including mortar and tank ammunition, the annual production capacity should thus be 500,000.

Also next year, STV Group wants to produce 500 million pieces of small-caliber ammunition annually.

But back to large-calibre ammunition. STV Group is upgrading the equipment for casting explosives into mortar shell bodies. Several Czech companies are now also involved in the production of shell bodies to reduce dependence on imports from foreign countries. STV Group is also planning to produce its own smokeless powder for large-calibre ammunition, with a target of 1,500 tonnes per year. A project is also underway to produce initiators, known as igniters, for ammunition.

2) New acquisitions and portfolio expansion with new products.

In the second half of this year, STV Group bought the Slovak company MATADOR Industries - a company engaged in automation, production of parts for the Zuzana-2 SpGH and machinery and equipment for the rubber industry. As STV Group, or rather the parent STV Invest, is not a pure defence industry company, MATADOR Industries fits into its portfolio.

However, the reason for the acquisition is probably quite different. The STV Group plans to start the complete development and production of AFVs and heavy weapons at MATADOR Industries, including towed howitzers. Production should start next year and annual production should be several dozen vehicles per year.

STV Group has also launched new unspecified projects - for example for the Israeli company Elta Systems or for the Swedish company BAE Systems AB.

πŸ‡¨πŸ‡Ώ BVP-1MA & BVP-1MB - Czech modernization of BVP-1 from the turn of the millennium

🧡[THREAD, 1/7]Image
In the 1990s, the state enterprise VOP-026 tried to modernize the old BVP-1 (licensed Czechoslovakian-made BMP-1). This modernized BVP-1 was to form the backbone of the mechanized units of the Czech Army.

The first and only prototype was presented in May 1999 in Brno at IDET β€˜99. The aim of the modernisation was to improve and increase the combat value of the vehicle at the lowest possible cost - firepower, ballistic and mine protection, handling and reliability were to be improved.

2/7Image
Specifically, the bottom of the hull was strengthened to increase mine resistance and the possibility of installing additional armour. Automatic fire extinguisher and explosion prevention equipment from the German company Kidde-Deugra was installed, the fuel tanks received anti-detonation fillings from the Greek company KAPA SA, a laser warning system, and laser filters for sights, independent heating, thermal insulation and anti-slip surface was installed. Suspension dampers were added and torsion bars replaced. The vehicle was modified for operation on public roads, i.e. the exterior lighting and turn signals were replaced, rear-view mirrors were added, brakes were refurbished and the tracks received rubber pads.

πŸ‡¨πŸ‡ΏT-72M4CZ - the sad story of one of the best T-72 modernization projects

[THREAD]Image
Czechoslovakia has been the operator of several hundred T-72 tanks since the 1980s and the manufacturer since 1981, with efforts to modernize these tanks dating back to the second half of the 1980s, when Czechoslovakia wanted to equip its existing fleet of T-72s with the 1A40-1 fire control system (FCS). The Soviet Union, the original manufacturer of the T-72 tanks, proposed to supply Czechoslovakia with new T-72S and then T-72S1 tanks, but after the fall of communism and the change of political orientation in Czechoslovakia the purchase was abandoned.Image
After the fall of communism, the main impuls in Czechoslovakia for upgrading the T-72M and T-72M1 tanks came from the 1991 Gulf War, when Western coalition tanks (especially the M1 Abrams and Challenger 1) clearly outclassed the Soviet designed tanks in Iraq's arsenal (interestingly, Iraq also operated several dozen T-72 tanks manufactured in Czechoslovakia).Image

Czech Heavy Weaponry In Ukraine

On February 24, 2022, Russian troops launched an unprovoked and brutal invasion of Ukraine. The Czech Republic and Czech private companies reacted immediately and immediately began sending much-needed weaponry to the Ukrainian defenders to withstand the initial onslaught.

Mi-24V/35

The Mil Mi-24V/35 Hind-E is a twin-engine attack helicopter designed for direct support of ground units, it has the unique ability to transport up to 8 people or 1500kg of material in the cargo area. It is armed with a 12.7mm four-barreled 9A624 rotary machine gun and can carry up to eight 9M114 ATGMs, 55mm S-5 or 80mm S-8 rockets, UPK-23-250 cannon containers with a 23mm GSh-23L twin-barreled cannon, GUV9A universal containers with the possibility of installing a 30mm automatic 9-A-800 grenade launcher or one 12.7mm four-barreled 9-A-624 machine gun and two 7.62mm four-barreled 9-A-622 machine guns, and more...

The Czech Republic received 17 Mi-24V/35 attack helicopters, manufactured between 2003 and 2005, as compensation for Russia's debt to the Czech Republic. The helicopters received subsequent modifications compared to the classic Mi-24V: TV3-117VMA engines, EVU engine exhaust gas cooling system, cabin and exterior light modifications for use of night vision system including custom night vision scopes, GPS satellite navigation system (Garmin-155 XL type), backup artificial horizon (type LUN 1241 of Czech manufacture), VARTA batteries, civil identification system transponder (IFF), which allows flights over the territory of the Czech Republic without restrictions, new elements for signaling and recording of flight parameters , altimeter calibrated in feet. Later modernization (~2017) included stabilized platform with FLIR night vision optoelectronic system, multi-function displays including moving map system, upgraded communication and navigation equipment, incorporation of an friend/foe aircraft identification system (IFF), planning and combat support system.

Four Mi-24V/35 helicopters were donated to Ukraine in May 2022, with 2 apparently serving as a spare parts source and two participating in combat missions (No.3362 and No.3370), further helicopters were promised in July 2023.

By December 2023, all remaining Mi-24V/35 of the Czech Air Force were grounded and apparently almost all will be sent to Ukraine in early 2024.Image

Samopal vz.58

SA vz.58 is an assault rifle in caliber 7.62x39mm, manufactured by ČeskÑ Zbrojovka Uherský Brod. It exists in two basic versions - P, with a fixed stock, also known as PÑdlo "Paddle", and V, with a folding stock, also known as Kosa "Scythe". The government decided to deliver to Ukraine on February 26, 2022, the third day of the invasion, in the amount of 5,000 units.

CZ Bren 2

The Bren 2 is an assault rifle manufactured by ČeskÑ Zbrojovka Uherský Brod. They went to Ukraine directly from the production plant and were originally intended for the Czech Army, and part of them were apparently ČZUB stocks. In Ukraine, they were seen in both versions - 5.56x45mm NATO and 7.62x39mm. It is found mainly in the equipment of the GUR MO, the International Legion and foreign units within the Ukrainian Ground Forces.
