OTO Melara Mod 56 In Ukraine

We’ve examined a number of artillery systems in use in Ukraine, including the venerable M101 howitzers and the MT-100s mounted on MT-LBs, one of the smallest and most interesting howitzers in use is the OTO Melara Mod 56.

The Mod 56 is a small 105mm pack howitzer. It weighs in at 1.29 metric tons and it can be towed by light vehicles. It has a split trail gun carriage and a hydro-pneumatic recuperator assembly. Developed by Italy’s OTO Melara the gun entered service in the mid-1950s and has seen service with countries around the world including Italy, the UK, Australia, Spain, Pakistan and the Philippines.

Much like the heavier M101 howitzers, transferred to Ukraine by Lithuania, the Mod 56 can use any M1 105mm ammunition. With its short 1.47 metre-long barrel, the Mod 56 has a maximum effective range of around 10,000 metres (10km/6 miles). While this puts it at a severe disadvantage compared to the larger 155mm howitzers used by Ukraine and the 152mm guns used by Russia the small Mod 56 has the advantage of being lightweight and can be deployed forward under cover. The most useful role it could likely fulfil is as an infantry support gun.

In November 2022, Spain’s Defence Minister Margarita Robles confirmed that Spain would send a battery of six light howitzers and also provide training for Ukrainian gun crews. Subsequently, a brief clip of Ukrainian gunners training on the Mod 56 was shared in late November.

The guns were seen in Ukraine for the first time in early January, with a short clip of one of the guns firing being shared on 11 January. It appears the gunner is wearing a National Guard patch but its unclear which unit the gun belongs to. On 12 January, the 1st Mechanized Battalion of Ukraine’s 3rd Assault Brigade posted an info-graphic giving some basic detail on the Mod 56.

On 20 February, a brief clip of a Mod 56 was shared, the footage was believed to have been taken in the vicinity of Bakhmut. However, photographs taken by an AP photographer, Libkos, of the same gun showed that the gun was actually in action in Avdiivka, Donetsk. The series of photographs also showed that the gun was being operated by a National Guard unit and the crew was using drone footage to select their targets. One photograph was also shared by President Zelensky on 5 March. Interestingly, the gun is seen without its shield.

Another video of one of the guns in action was shared on 16 April. It was several months before more imagery of the Mod 56s in use appeared but on 1 June, the Ukrainian National Guard shared a photograph of one of the guns and several days later, on 3 June, a short video of a gun in action was shared.

Most recently on 19 July, a Ukrainian National Guard unit shared a brief clip of a Mod 56 firing. It also nicely illustrates the gun’s breech mechanism.

From the available imagery, it appears that the guns are operated by Ukraine’s National Guard, though which artillery unit is unclear. While it has been confirmed that Spain has provided at least 6 Mod 56 howitzers, it remains unknown if any other countries, such as Italy, have provided the small guns.

Update – 29/12/23:

An undated sighting of a Mod 56 in operation in Ukraine. Notably half of the gun shield appears to be missing.

Update – 17/04/24: A clip posted on 7 April, date of recording unconfirmed, showing a Mod 56 in action. The howitzer’s gunshield has been removed.

Top Attack SMArt155 In Ukraine

SMArt 155 is a Sensor Fuzed Munition (SFM), developed by Rheinmetall and Diehl BGT Defence in the late 1980s. It is a 155mm howitzer round which contains a pair of fire-and-forget top-attack submunitions. The submunitions use a ballute and parachute to slow their descent and allow the submunitions’ onboard infrared sensor and millimeter wave radar to locate its target and fire and explosively formed penetrator.

In a previous video/article we’ve looked at the 155 BONUS round which also carries two submunitions which are arrested by a pair of winglets which arrest the submunitions flight to enable their built-in sensors to detect targets within their search footprint before striking down on a target vehicle.

The round is manufactured by GIWS, a joint venture between Diehl Defence and Rheinmetall, and entered service in the late 1990s. It is capable of being launched by NATO standard 155mm howitzers but in Ukraine appears to primarily be used in conjunction with Panzerhaubitze 2000 self-propelled howitzers. The round is also in British service as the Ballistic Sensor Fused Munition fired from AS-90s, the UK has recently provided Ukraine with a number of AS-90s but it is unclear if they will deploy SMArt155 rounds.

The manufacturer describes SMArt 155 projectile as consisting of: “a thin-walled shell body, a base plate, an ejection unit, time fuse, and two functionally identical submunitions.” The SMArt155 round allows a 155mm projectile to deliver two submunitions capable of penetrating any tank’s top armour with considerable accuracy. SMArt155 has a listed maximum range of 22km (13.6 miles) when fired from 155mm/39-calibre systems and 27.5km when fired from 155mm/52-calibre systems such as the PzH2000. Adding a base bleed unit would extend the round’s range further. The submunitions carry a shaped charge of 9.7lbs (4.2kg) of high explosive which create explosively formed penetrators (EFP). The manufacturer states that extensive German Army trials found that the round has a very low failure rate.

Once the round is fired an onboard timer fuze, set before firing, ignites an ejection charge in the shell’s nose which pulls the submunitions out of the shell body. Once clear the submunitions’ ballute and then parachute deploys they begin to spiral down over the target area using their onboard sensors to detect the target vehicle before detonating their payload.

Though there is controversy surrounding SMArt, and BONUS, the shells do not fall into the category of weapons banned under the 2008 Convention on Cluster Munitions as they comprise of just two submunitions and both have onboard self-destruction mechanisms.

The summer of 2022 saw a flurry of drone videos which showed strikes of Russian vehicles and equipment many of these were attributed to either BONUS or SMArt 155, but with most of the videos it is difficult to definitively identify which top attack munition was in use.

On the 2 July, the first video believed to be a SMArt in action was shared online. In it a munition can be seen descening before detonating above. The framing and resolution of the video is too low to confirm if it is a parachute arrested submunition. Russian telegram channels shared a photograph of a ballute and parachute, said to have been seen near Kirovsky, in Donetsk in early August.

On the 13 September, another fairly low resolution video showed a top attack munition detonating above a Russian armoured vehicle. On 4 March 2023, photos of a ballute and parachute from a SMArt 155 were shared and said to have been found near Kreminna. Around the same time another video showing a potential SMArt 155 strike was shared. On 17 April, the 26th Artillery Brigade shared video showing what was claimed to be a SMArt munition striking two Russian vehicles. On 23 April, Ukrainian military journalist Andrii Tsaplienko shared a video from inside a PzH2000 showing some German DM702 SMArt 155 shells. The DM702 shells were again briefly seen in a video posted by the 43 Separate Artillery Brigade posted on the 16 May.

While the lack of easily verifiable videos of SMArt in use is frustrating it is impressive that we have any footage of top-attack munitions in use at all. Production of SMArt 155 paused in the late 2000s but even before the war in Ukraine began their had been plans to revive production. The war has, however, provided impetus for renewed production and in late 2022 the German government agreed to spend EUR 97.4 million to restart manufacture of the complex electronic components needed to manufacturer the round.

Ukraine’s Newest Howitzer Is An Antique

Plenty of old weapon systems are in use in Ukraine and artillery is no exception. This week the first footage of a batch of 105mm howitzers from Lithuania in action was shared online.

Lithuania has transferred an undisclosed number of M101 towed howitzers. While the 105mm gun lacks the range and punch of the 155mm M777s, Caesars, AHS Krabs and PzH 2000s which have made headlines in recent months, the venerable M101 is a proven weapon.

Introduced in 1941 as the M2A1, the gun has seen service around the world. First during the Second World War and later in Korea, Vietnam and in dozens of regional conflicts around the world. Now it finds itself equipping Ukrainian Army batteries.

The M101 weighs in at 2.5 tons or 2,260 kg and firing conventional M1 high explosive shells has a maximum range of 11,500 metres or just over 7 miles. The M1 round is made up of the  the M1 High Explosive projectile, the M14 Cartridge Case, the M67 Propelling Charges and the M28 Percussion Primer.

The Baltic nation of Lithuania, has been a staunch supporter of Ukraine throughout the conflict providing equipment, arms and training. Lithuania  originally received 54 of the guns from Denmark in 2002. Now, as Lithuania upgrades to 155mm systems the old guns have found a new home. While it is unconfirmed whether Ukrainian troops trained to use the guns in Lithuania, Ukrainian troops have been training in the Baltic nation.

The first guns were shipped in September, with the Lithuanian Minister of Defence announcing the transfer on his social media, but the first footage of them in action in Ukraine didn’t surface until late November.

While the M101 may be old it has the major advantage in that if fires the readily available family of 105mm NATO ammunition. This 105mm ammunition is used by a number of light artillery systems including the more modern US M119A3 and L119 towed 105mm howitzers. As of November 2022, the US has provided 180,000 rounds of 105mm. 

While the M101 may seem like a step down from the 155mm systems in use it has a number of factors which mean the guns are still effective. Firstly, they are used in conjunction with drones which help adjust fire in real time to produce improve effect on target. Secondly, they can use M927 rocket-assisted projectiles which increase the gun’s range by 40%, around 17km. M927’s were first seen in late August being used in conjunction with L119 light guns.

The M101 is certainly an improvement over the 85mm D-44 guns that some Ukrainian Territorial Defense Force units have been seen using and the venerable 100mm MT-12 which has a range of just over 5 miles. While the M101 can’t hope to go toe to toe with Russian 152mm artillery, if used in its original role as an infantry support gun the venerable M101s will prove useful. 

Update 07/12/22: Another short clip of an M101 in action was shared on the 7 December, showing the more closely than previous footage.
