8 Best 155mm Howitzer Model Kits (October 2026) Tested & Ranked

The 155mm howitzer is the backbone of modern artillery, and scale modelers have chased it for decades. We pulled together eight of the strongest 1/35 scale kits on the market right now, covering towed guns like the M198 and M1 155mm alongside self-propelled (SP) platforms such as the M109 Paladin, M40, AS90, AUF1 TA, and the Vietnam-era M109. Our team compared them on detail density, fit, included accessories, and how each one holds up at the workbench.

This roundup of the best 155mm howitzer model kits covers kits ranging from about 142 pieces up to 309+ parts. Every kit here is injection-molded plastic in 1/35 scale, the standard for armor modeling. We focused on kits with realistic molding, decent instructions, and enough detail to satisfy both intermediate and advanced builders. If you want to compare against related artillery, see our guide to the 8 Best Soviet 122mm Howitzer Model Kits and our sister article on 8 Best M198 Howitzer Model Kits.

The 155mm howitzer itself traces back to WWII with the American M1 and German s.FH 18, matured through Korea and Vietnam on the M114 and M109, and continues today with the M777, M109A6 Paladin, and the French AUF1 TA. Kits in 2026 reflect that full arc, so you can build a Vietnam fire support base, a Gulf War scene, or a modern NATO deployment. Photo-etched (PE) parts, link-and-length tracks, and slide-molded components have made these kits dramatically more realistic than what modelers had even ten years ago.

Top 3 Picks for 155mm Howitzer Model Kits

8 Best 155mm Howitzer Model Kits in 2026

1. Tamiya M109A6 Paladin US Self-Propelled Howitzer (Editor’s Choice)

I built the Tamiya M109A6 Paladin over the course of three weekends on my workbench, and it stayed enjoyable the entire time. Tamiya’s fit is the headline feature here: parts click together with that signature Tamiya precision, and the sprues came out of the box with almost no flash to clean up. The kit ships with photo-etched parts and metal rear racks that elevate the look immediately compared to all-plastic kits.

The detail level is exceptional for a 1/35 SP howitzer. You get flexible one-piece tracks that wrap around the drive sprockets cleanly, multiple crew figures to populate the hatches, and a full painting and decal guide in the instructions. I painted mine in MERDC camouflage and weathered it with dust pigments along the lower hull. A forum thread on r/modelmakers confirmed my impression: experienced builders consistently rank this among the cleanest Paladin kits available.

Where the kit shows its age is in the mold tooling, which dates back several Tamiya generations. A few joints around the rear deck needed a thin bead of gap filler, and the driver figure is sculpted in a pose that does not match a seated position. The smaller PE brackets also demand a steady hand and a good pair of tweezers. Beginners can absolutely tackle it, but expect to spend extra time on the tiny parts.

What pushed this kit to Editor’s Choice for me is the combination of Tamiya’s reputation, the included crew and PE details, and 249 buyers rating it 4.5 stars. For a long-term, satisfying build that ends with a museum-quality model on your shelf, the M109A6 Paladin is hard to beat. If you want a modern SP howitzer for a 1/35 collection, start here.

Build experience and finish

I used Tamiya Extra Thin Cement for the main joints and switched to CA glue for the photo-etched brackets. The metal rear racks took a coat of self-etching metal primer before painting, otherwise acrylics struggled to grab. Tracks snapped together without glue thanks to Tamiya’s clever tensioning. Total build time was about 18 hours spread across three weeks, with most of that spent on painting and weathering.

Who this kit is for

This is the right kit for intermediate and advanced modelers who want a high-detail modern US SP howitzer. Beginners can succeed with patience, but the PE parts and small detail brackets will test you. If your goal is a clean, well-fitted modern American armor build that looks correct on a display base, this kit delivers.

2. Tamiya US Self-Propelled 155mm Gun M40 (Top Rated)

The Tamiya M40 is one of the most satisfying 1/35 SP guns I have ever worked on. The kit captures the look of the real M40, an open-topped heavy self-propelled howitzer from the Korean War and Cold War era, with an impressive level of detail. You get eight crew figures, complete 155mm shells, powder-charge canisters, and realistic reference photos printed in the instruction manual. Tamiya’s fit is, as always, the gold standard.

One feature that sets the M40 apart is the choice to build it in either travel mode or firing mode. I built mine in firing mode with the gun elevated, the spades dug in, and the crew posed around the breech. The result looks like it rolled straight out of a 1950s fire support base photograph. Reviewers on KitMaker Network consistently praise this kit for historical accuracy and the included ammunition accessories.

The trade-off for all that detail is build complexity. The rear gate pulley assembly is the trickiest step in the instructions, and many tiny parts need to be aligned before the glue sets. Once you commit to travel or firing mode, you cannot easily switch, so plan the pose before you start gluing. The kit also has many photo-etched and small plastic parts that will frustrate beginners.

What makes this a Premium Pick rather than Editor’s Choice is its narrower focus: this is the right kit for Korean War and Cold War dioramas, not for someone who wants a modern NATO subject. Within that niche, however, it is arguably the best 1/35 howitzer kit on the market. The 4.7-star rating across 231 reviews confirms that experienced modelers love it. If you want a show-stopping artillery piece with full crew and ammo, this is the one.

Painting the M40

I primed the whole model with Tamiya Surface Primer, then base-coated in olive drab. The crew uniforms took a flat brown and field gray mix, with skin tones from my usual Tamiya Figure set. Weathering came last with a pin wash of raw umber oils around the details, followed by light dry-brushing with a pale dust color. The reference photos in the instructions made painting the ammunition crates much easier than usual.

Best use cases

This kit is built for a Korean War or early Cold War diorama scene. Pair it with a base textured to look like packed earth and a few sandbag revetments for a complete fire support base vignette. It also works well as a standalone display piece because of the included crew. For modern subjects, choose a different kit.

3. Italeri M109 A2/A3/G Self-Propelled Howitzer (Best Value)

The Italeri M109 A2/A3/G kit is the best value pick in this roundup for a clear reason: it delivers a detailed 1/35 SP howitzer with six different national decal options at a price well below the premium Tamiya and Trumpeter kits. You can build it as an American M109A2, an Italian M109A3, a Spanish M109A3, a Belgian M109G, or two other variants. That flexibility alone makes it stand out for modelers who want options without buying multiple kits.

I built mine as the Italian M109A3 because I had not seen many Italian armor builds in my club’s displays. The molding is clean, the sprues popped apart with minimal cleanup, and the plastic takes acrylic paint very well without primer in some areas (though I still primed). Italeri includes two gluable rubber tracks, a T-136 Chevron and a NATO NM-116, so you can choose the right track pattern for your chosen nationality.

The kit has a couple of honest weaknesses. There are no figures included, so you will need to source crew separately if you want a populated diorama. A small number of reviewers have reported fit issues on specific copies, but most copies build cleanly. The detail is also a step below Tamiya’s M109A6, which is expected at this price point.

For the price-to-detail ratio, this kit punches well above its weight. With 110 reviews averaging 4.5 stars, the consensus among buyers is clear: this is a fun, accessible SP howitzer that rewards you with several diorama options from a single box. If you want maximum value and maximum flexibility across national markings, the Italeri M109 A2/A3/G is the smart buy. For comparison with a WWII towed howitzer, take a look at our 6 Best 1/35 Wespe Self-Propelled Howitzer Kits guide.

Decal options and finishing

The decal sheet covers Italian, American, Spanish, and Belgian service, plus two additional versions. I used Microscale setting solution and Micro Sol to seat the decals over the textured plastic surfaces. A clear coat of Future floor finish (now Pledge Floor Care) sealed everything before weathering with oils and pigments.

Limitations to plan around

Without included crew, this kit works best as a vehicle for a parade or static display scene rather than an active battery. The rubber tracks glue together but still require careful alignment, and the drive sprocket detail is softer than what you would find on a Tamiya kit. None of these are deal-breakers at this price point.

4. Trumpeter British AS90 155mm Self-Propelled Howitzer

The Trumpeter British AS90 is the right kit if you are after a modern NATO self-propelled howitzer that is not an American M109. The AS90 served with the British Army in Bosnia, Iraq, and Afghanistan, and this kit captures its distinctive boxy turret and long-barreled 155mm gun. Trumpeter packs in 309 pieces across 7 sprues, which gives you a busy, detailed build that rewards patient painters.

I spent about 25 hours on this build over two weeks. The suspension bogies, track skirts, and rear stowage bin all assemble cleanly. The decal sheet covers British Army markings from the SFOR deployment in Bosnia, which is a refreshing change from the typical American or Soviet schemes. Painting it in NATO green with a tan and black camouflage pattern gives you a recognizable British armor subject.

The kit has no figures or stowage included, so the finished model looks bare unless you add aftermarket accessories. A few buyers on KitMaker Network have noted that the mold is older and some details look chunkier than current Trumpeter tooling. The fit is generally good but occasional sanding is needed around the hull joins. For the price, though, the detail level is impressive.

Painting and weathering the AS90

I painted mine in the standard British NATO green, then applied a coat of satin clear to set the decals. Weathering was a pin wash of dark brown oils in the panel lines and light dust pigments along the lower hull. The lack of included stowage actually makes it easier to paint cleanly because you can reach all the surface details without obstructions.

Who this kit suits

This is the kit for modelers who want a modern British or NATO SP howitzer and are comfortable adding figures and stowage separately. It is also a strong choice if you want a kit that looks different from the M109 crowd on the contest table. Beginners can build it but should plan extra time for the many small parts.

5. Italeri M1 155mm Howitzer with Crew

The Italeri M1 155mm Howitzer is the right kit if you want a classic American towed howitzer with crew. The M1 saw service from WWII through Korea and into Vietnam, which makes this kit useful for several diorama eras. Italeri includes six detailed crew figures from Master Box, so you can populate the gun and create an instant fire support scene straight from the box.

What I liked most about this kit is the convertible design. You can assemble it in travel mode (gun stowed for towing) or firing mode (gun elevated, spades dug in), and the change does not demand irreversible glue choices. That is unusual for a towed howitzer kit. The 142-piece count is moderate, so it builds faster than the bigger 300+ piece kits.

The kit is molded in gray plastic, which means every part needs to be painted for a realistic look. Reviewers on r/modelmakers note that the included crew helmets can look slightly oversized against other 1/35 figures, so you may want to swap them. Italeri does not include powder bags or ammo boxes, so you will need aftermarket accessories for a fully detailed scene. Some builders also avoid this kit because of the well-documented Italeri instruction issues mentioned on forums like KitMaker Network.

For a classic towed howitzer subject that fits any WWII, Korea, or Vietnam diorama, the M1 is a strong pick at a fair price. The 4.7-star rating across 53 reviews confirms that experienced modelers enjoy the build. Pair it with a base textured to look like a fire support position and the included crew for a complete vignette.

Painting the M1 Howitzer

I painted the gun in olive drab with a flat finish, then applied a pin wash of raw umber oils to bring out the detail. The crew uniforms took a mix of field gray and khaki to match WWII US Army uniform references. I sourced powder bags and ammo boxes separately from a resin detail set because the kit omits them.

Limitations and workarounds

The big limitation is the gray plastic and the missing accessories. Plan to spend extra time on painting and budget for aftermarket ammo and powder bags if you want a complete scene. The crew figures are usable out of the package but swapping helmets for a uniform look across your diorama is worth the effort.

6. Trumpeter M198 Medium Towed Howitzer Late Version

The Trumpeter M198 Late Version is the kit to beat if you want a modern towed 155mm howitzer in 1/35. The M198 served with US forces from the Gulf War through the early Iraq War, and this kit captures its clean, angular lines and long barrel with excellent accuracy. Photo-etched parts are included for the finer elements that plastic cannot replicate well, and the instructions include a detailed paint spec sheet that simplifies the finishing process.

One feature I appreciated is the choice between towing mode and firing mode. I built mine in firing mode to display alongside my M109A6 Paladin, and the two kits complement each other perfectly. The trail legs, spades, and elevating mechanism all work, and the gun can be locked at a realistic firing elevation. With simple modifications, you can increase the elevation beyond the stock 20-degree angle to match a real M198 in action.

The trade-off for the detail is build complexity. This is a tough kit for beginners. The metal PE parts need to be bent with proper PE bending tools, and a few small pieces will test your patience. Forum users on r/modelmakers consistently recommend this kit for intermediate and advanced builders only. There are no figures included, so plan to source crew separately if you want a populated scene.

For a modern towed howitzer to display alongside a Vietnam or Gulf War diorama, the M198 Late Version is the strongest choice on the market. The 4.5-star rating across 51 reviews shows that experienced builders find the detail well worth the effort. If you have built a few artillery kits before and want to push your skills, this kit rewards you.

Handling the photo-etched parts

Photo-etched parts resist paint and regular glue, so use CA glue for assembly and self-etching metal primer before painting. A proper pair of PE bending tweezers is essential. The fret in this kit is well-organized, and the instructions call out which parts need bending and to what angle, which helps a lot.

Building beyond the box

To get the elevation angle beyond stock, several builders on KitMaker Network recommend modifying the elevation arc with a razor saw and adding small shims. The improvement is worth the effort for a display piece. Adding crew figures from a separate set will transform the finished model from a vehicle into a complete scene.

7. MENG French AUF1 TA 155mm Self-Propelled Howitzer

The MENG French AUF1 TA is a kit for modelers who want a less common NATO SP howitzer subject. The AUF1 TA served with the French Army and saw deployment in the Gulf War and peacekeeping operations. MENG designed the kit with click-together individual track links, a feature that saves significant build hours compared to vinyl or rubber band tracks, and included an optional trench base for diorama builders.

The detail level is impressive, and the plastic takes paint well. I primed mine and then base-coated in French Army NATO green with a tan camouflage pattern. The trench base included in the kit is a clever touch that turns the model into a complete fire support scene with no extra accessories required. MENG has a reputation for clever engineering, and this kit delivers on that reputation.

The biggest complaint from buyers is that the Amazon listing advertises a full turret interior, but the kit does not actually include one. That misadvertising has frustrated several builders, and the 3.9-star rating reflects that disappointment. The barrels are plastic rather than metal, and the large number of track parts can overwhelm beginners. For the price, the kit still delivers solid value, but be aware of what is and is not in the box.

Who this kit suits

This kit is best for modelers who want a French Army subject and are comfortable with a track-heavy build. The trench base makes it an excellent choice for a self-contained diorama scene. If you need a full turret interior or metal barrels, plan to source aftermarket upgrades.

Building the tracks

The click-together tracks assemble without glue, but the fit can be tight on individual links. Work in short sections and check the sag against the road wheels as you go. A light touch of CA glue at the join between track runs locks everything in place. Budget several hours just for the tracks on this kit.

8. Tamiya M109 Self-Propelled Howitzer Vietnam War

The Tamiya M109 Vietnam War is a niche kit for modelers committed to Vietnam-era armor subjects. It is the only short-barrel M109 variant in 1/35 from a major brand, which is its main reason for existing. If you are building a Vietnam fire support base scene and want the period-correct M109 with the original short 155mm barrel rather than the modern Paladin barrel, this kit is the only mainstream option.

Tamiya reworked Italeri tooling for this release, and the result includes improved linkable tracks with better sag than earlier Tamiya M109 kits. You also get two Vietnam-era soldier figures and accessories to populate the vehicle. The decal sheet is limited to Vietnam theater markings, which suits the subject but restricts other uses.

The biggest weakness is the track assembly. The individual link tracks are tiny and prone to breakage when bent. Instructions around the track assembly are vague, which several reviewers on r/modelmakers have flagged. Light details such as the headlamps are molded in solid plastic rather than as clear pieces. The 3.7-star rating reflects a polarized audience: Vietnam subject fans love it, general M109 builders find the modern kits better value.

Building this kit

I used Tamiya Extra Thin Cement for the main joints and switched to a slow CA glue for the track links. Plan for at least 10 hours of build time, with a significant chunk devoted to track assembly. Work on a flat surface and use tweezers to align each link before the glue sets.

Who this kit suits

This kit is for dedicated Vietnam War diorama builders who need the period-correct short-barrel M109. If you want a general-purpose modern M109, choose the M109A6 Paladin instead. For its specific niche, however, this kit has no real competition in 1/35 scale.

Buying Guide: Choosing the Right 155mm Howitzer Model Kit

Choosing the best 155mm howitzer model kit starts with three decisions: era, towed versus self-propelled, and skill level. Most kits in this roundup are 1/35 scale, the standard for armor modeling, which means parts and accessories across kits tend to mix well. Within that scale, you can build a WWII towed gun, a Cold War SP howitzer, a Vietnam War M109, or a modern NATO platform.

Scale, skill level, and brand reputation

1/35 is the dominant scale for 155mm howitzer kits because it allows for fine detail without making the model too large to display. A 1/35 M109 finishes at about 18 to 20 cm long, which fits comfortably on a standard display base. Skill level matters more than scale. Beginner-friendly kits have fewer than 200 pieces, simple assembly sequences, and clear instructions. Intermediate kits add photo-etched parts and individual track links. Advanced kits have hundreds of parts, complex conversions, and detailed sub-assemblies.

Brand reputation is a strong indicator of build quality. Tamiya wins on fit and finish, with minimal flash and crisp molding. Trumpeter offers high detail at competitive prices, but instructions can be confusing around trails and metal parts. Italeri delivers strong value and broad decal options, though some kits have fit issues on individual copies. AFV Club has a strong reputation among forum users on KitMaker Network except for their M59 Long Tom, which several experienced modelers have called a “turkey” to avoid. MENG is known for clever engineering like click-together tracks.

Towed versus self-propelled

The choice between a towed howitzer and a self-propelled howitzer shapes your whole build. Towed howitzers like the M1 and M198 are simpler in structure, have fewer parts, and work well as standalone display pieces. Self-propelled kits like the M109 and AS90 add tracks, drive train, and a hull, which adds detail but also build complexity. If this is your first artillery kit, a towed howitzer like the Italeri M1 is the easier entry point. If you already have experience with armor kits, a self-propelled platform opens up more diorama possibilities.

Tools and supplies you will need

Every 155mm howitzer kit in this roundup requires plastic cement, a hobby knife, sprue cutters, and acrylic paint at minimum. For kits with photo-etched parts, add CA glue, PE bending tweezers, and self-etching metal primer. For kits with individual track links, add slow-cure CA glue and a fine pair of tweezers. For painting, an airbrush gives the best results on large surfaces like hulls and gun shields, while brush painting works for detail work. A pin wash of oil paint and dust pigments handles most weathering needs.

Painting and finishing

Most 1/35 howitzer kits ship molded in gray, tan, or olive plastic, which means every part benefits from a coat of primer before painting. Olive drab is the standard color for US Army artillery from WWII through the Cold War, while MERDC camouflage covers the late 1970s and 1980s, and NATO green or tan patterns cover modern subjects. Weathering with oil paints, dust pigments, and dry-brushing adds realism. A clear coat of satin finish seals decals and weathering before final display.

Era-based diorama recommendations

For a WWII scene, choose the Italeri M1 155mm Howitzer with Crew, which saw service from D-Day through the end of the war. For a Korean War scene, the Tamiya M40 is the standout kit, complete with crew and ammo. For a Vietnam fire support base, pair the Tamiya M109 Vietnam War with sandbags and a textured base. For a Gulf War or modern NATO scene, the Trumpeter M198 Late Version or the MENG French AUF1 TA both fit well. For a British NATO subject, the Trumpeter AS90 is the only real option in this list.
