Mk153 SMAW In Ukraine

Recent imagery confirms the presence of the Mk153 SMAW in Ukraine. In the last couple of months there have been sightings of the Mk153 in use at the front and at a Ukrainian Armed Forces training ground. The Mk153 is a shoulder-fired rocket launcher capable of engaging structures and armoured vehicles.

The Mk153’s cousin munition – the one-shot, disposable M141 SMAW-D has been seen in theatre in fairly small numbers since February 2022. We have an earlier article/video looking at the SMAW-D, check that out if you haven’t already.

The Mk153 is primarily used by the USMC and was developed from the Israeli IMI B-300 and introduced in the mid-1980s. So what actually is a Mk153? The USMC describes the SMAW as: 

“a one-man operable, 83 mm smooth bore, shoulder-fired, rocket launcher with a spotting rifle attached to the right side of the launcher tube. The encased rocket is fitted into the aft end of the launcher, and the fiberglass encasement is discarded after use. The spotting rifle, which improves firstround hit probability, is fed 9 mm tracers by a magazine, which holds six rounds. The 9 mm round is ballistically matched to the 83mm rocket.”

The SMAW (or Shoulder-Launched Multi-Purpose Assault Weapon-Disposable) can fire Encased High-Explosive, Dual Mode (HEDM) and Encased High-Explosive, Anti-Armor (HEAA) rockets. The HEDM is an anti-structure and anti-light armour munition with a warhead containing 2.4 pounds Aluminized Comp A-3 capable of penetrating 200mm (8 in) of concrete. The HEDM has a maximum effective range of 250m. The HEAA is a dedicated anti-armour round able to penetrate up to 600mm (23.6in) of rolled homogeneous steel, with a maximum effective range of 500m. It uses a shaped charge warhead with 1.89 lbs Octol explosive. The Novel Explosive (SMAW-NE) has a 4lbs enhanced-blast warhead, containing PBXN-113, designed for bunker busting which the USMC manual describes as “designed to provide enhanced-blast lethality to defeat personnel in reinforced structures and caves.”

The Mk153 has iron sights and a Mk42 3.8× magnified optic and a 9mm spotting rifle on the side of the launch unit. This spotting rifle fires tracer rounds which match the rocket’s ballistics and can help range the target and aid the operator in applying the right hold for the target. The tracer cartridge that contains a 9mm jacketed bullet with an aft burning .22 calibre tracer element. Spotting rifle magazines for the rockets are supplied on the outside of the rocket carry tube end cap.

The first sighting of a Mk153 in the field came from some B roll footage of a UK Channel 4 News report published on 28 February. It showed men of the Ukrainian 68th Jager Brigade on the front-line near Vuhledar. Several soldiers are seen preparing a Mk153 to fire.

On 17 March a video featuring a Mk153 SMAW being fired at a range was shared on Telegram. It shows a SMAW being fired and a pile of spent tubes and unfired rockets on the ground. The fired and unfired rockets all appear to have yellow bands indicating high explosive munitions – the Mk153’s practice round has a brown band. Sadly, we can’t  make out the other markings which would indicate the type of rounds being fired.

At the end of March another video of Ukrainian soldiers preparing a Mk153 for firing was shared again at the range. The video gives us the best close up of the launcher in theatre so far and shows not one but two launch units. We get a good look at the tube and the launch unit’s spotting gun on the right hand side. This video shows the weapon being prepared to fire, the rocket is inserted into the launcher and rotated clockwise a quarter-turn to lock it in place before the Ukrainian soldier fires at a target down range.  

Another interesting detail we can see is the white paper hang ing from the rocket. This is a humidity indicator which allows quick visual inspection to see if the rocket might have been compromised by moisture. The indicator on this rocket appears to have pink in all three of its indicators circles, meaning the munition might be compromised, in USMC service this would mean the rocket needs to be returned to the ammunition supply point. Despite this the rocket appears to fire normally and detonate down range. It’s worth noting that the launch unit isn’t fitted with an optic in any of the clips.

Update – 24/05/23: An additional clip of a SMAW being fired in an urban environment, perhaps during the defence of Bakhmut, date unknown.

Update – 25/06/23: A photograph of a Ukrainian combatant with a SMAW share online, June 2023

Update – 25/07/23: A photograph originally posted in December 2022 showing a SMAW launcher with rockets in the background.

Update08/08/23: Short video of a Ukrainian combatant firing a Mk153 at a distant (judging by elevation) target.

Update – 3/9/23: An interesting video showing a phone mounted onto a SMAW MK153, this allows a clinometer app to be used to enable the SMAW to be used in the in-direct role, angling the weapon upwards.

Update – 24/09/23: Bravo Rapid Reaction Group training with SMAW Mk153 at the range.

Update – 3/4/23: A combatant from Ukraine’s 3rd Assault Brigade shared video on 27 March of a firing of a SMAW Mk153 at a range, filming date unconfirmed.

The SMAW-D In Ukraine

In recent days, with the news that a shipment of M141 SMAW-D anti-structure weapons have arrived in Ukraine as part of the US military aid shipments, a number of media articles and videos have been made on the subject which seem to confuse the SMAW-D with the AT-4 and even the M72. So, I thought it would be useful to take a look at the SMAW-D in a little detail. 

M141 (SMAW-D) (US Army Manual)

So What is the SMAW-D?  

Its official designation is ‘Rocket and Launcher, 83mm HEDP Bunker Defeat Munition (BDM), M141 (SMAW-D)’ SMAW-D stands for Shoulder-Launched Multi-Purpose Assault Weapon-Disposable. This isn’t to be confused with the Mk 153 Shoulder-Launched Multipurpose Assault Weapon used by the US Marine Corps. Those the SMAW-D did evolve from the SMAW.

The initial Mk 153 SMAW evolved from the Israeli IMI B-300. During the early-1980s McDonnell Douglas further developed the system and it entered service with the US Marine Corps as the Mk 153 in 1984. The SMAW-D shares the same warhead as the Mk 153 SMAW. The SMAW-D was originally developed by McDonnell Douglas and the design was acquired by Talley Defense Systems, whom were subsequently acquired by Norwegian company Nammo.

M141 (SMAW-D) (US Army Manual)

The Mk 153 has a reusable forward launch tube and firing mechanism which has a spotting rifle and can be mounted with an optic. The warhead element of the SMAW is attached at the rear of the launcher. The US Army was initially interested in the Mk153 but preferred a lighter, single use weapon.

In the early 1990s the US Army began the search for a disposable Shoulder-launched Multipurpose Assault Weapon. McDonnell Douglas offered a lighter, disposable version of the Mk 153, taking the Mk 153’s High Explosive, Dual Purpose warhead and pairing it with shorter burn rocket. In 1996 the US Army selected the SMAW-D, beating a Swedish design, the FFV AT8, and the Hunting Engineering LAW80. The SMAW-D entered service in 1999.

The SMAW-D is similar to the 66mm M72 in that it telescopes with the launch tube extended before firing. When collapsed it measures just under 32 inches in length but extending the inner tube gives the weapon an overall length of 55 inches. The launch tube and rocket weigh 15.7 lbs.

The tube has the firing mechanism mounted on the side under a plastic cover which when opened arms the rocket ready to fire. The weapon has front and rear iron sights for aiming. The SMAW-D can also be fitted with an AN/PVS-4 nightsight and various infrared aiming lasers for night fighting.

To fire the M141 the operator removes the locking pin from the front of the launch tube, depresses the tube release button and extends the inner tube rearward. The operator then raises the weapon onto the right shoulder, slides the front sight cover forward and then the same for the rear sight. Then opening the firing mechanism cover pivoting it forward, flush with the tube, this arms the weapon. The operator should then check the backlist area and fire when ready by depressing the safety button and then the red trigger button. The rocket is ignited by an electrical impulse sent by the firing mechanism. Once ignited the rocket burns out before it leaves the muzzle, this protects the operator.

M141 (SMAW-D) (US Army Manual)

The M141 can engage targets out to 500 metres but is most effective out to 300. Its 83mm unguided, fin-stabilised round has an integral high-explosive, dual-mode warhead with 2.38 lbs of explosive. Detonation is instantaneous when impacting on a hard target, such as a brick or concrete wall, or an armored vehicle. Impact with a softer target, such as a sandbagged bunker, results in a fuze time delay that permits the rocket to penetrate into the target before warhead detonation. It can penetrate up to 200mm (8 inches) of concrete, 300mm (12 inches) of brick and 2m (6 feet 6.74 inches) of earth or sandbags. It can also perforate up to 20mm (0.8 inches) of rolled homogenous steel giving the SMAW-D the ability to take on soft and light armoured vehicles. For training at the range a 21mm sub calibre training system can be used. While the usefulness of the M141 might be questioned, as it isn’t an anti-tank weapon and could be considered more of an offensive rather than defensive weapon it would no doubt prove very useful during urban fighting, which Ukraine anticipates in the event of an invasion.

The SMAW-D saw service with the US Army during the War in Afghanistan and during the Iraq War. Some 6,000 units were initially procured, with an unknown number procured since. It remains an active part of Nammo’s product line.

It is estimated that perhaps 100 M141 BDMs have been shipped to Ukraine so far as part of military aid, alongside small arms and ammunition, Javelin Anti-Tank Guided Missiles and NLAW anti-tank weapons from the UK. From the US Department of Defense’s packaging configuration table for the SMAW-D we know that each metal container holds one round and that 25 containers can be placed on a pallet. This appears to match up to the photos of the weapons being prepared for shipment. The Ukrainian Ministry of Defence and media have shared photographs of Ukrainian personnel training with M141s under the supervision of US troops. The training took place over two days at the 184th Training Center and the International Center for Peacekeeping and Security of the National Ground Forces Academy. These personnel will likely be tasked with then training other Ukrainian units on how to use the weapon.
