ARCA 155 mm Artillery Ammunition: M107 and ERFB-BB AR204

Last updated: 28 July 2026
Does ARCA make 155 mm artillery ammunition? Yes. 155 mm is NATO’s standard artillery calibre and the most strategic item in ARCA’s range. The catalogue lists two core 155 mm products: the classic M107 high-explosive shell and the ERFB-BB AR204, which extends range into the 40 km class.

ARCA’s 155 mm products
| Product | Class | Range (approx.) | Role |
|---|---|---|---|
| 155 mm M107 | High-explosive (HE) | ~20-24 km class (standard) | General-purpose artillery fire |
| 155 mm ERFB-BB AR204 | Extended-range, base-bleed | 40 km class (as presented) | Long-range artillery missions |
What is the 155 mm M107?
The M107 is one of the most widely used 155 mm high-explosive shells worldwide, a NATO-inventory standard for decades, designed for general-purpose artillery fire. By producing this well-established design in-house, ARCA serves a broad user base.
What is the 155 mm ERFB-BB AR204?
The ERFB-BB AR204 is ARCA’s long-range 155 mm solution. ‘ERFB-BB’ (Extended Range Full Bore – Base Bleed) creates a controlled gas flow at the shell base to fill the low-pressure wake, reducing drag and extending range. The company presents it in the 40 km class. Base-bleed technology is a common feature of modern long-range artillery ammunition.

Why 155 mm is strategic
155 mm is the common artillery calibre of NATO armies, and that standardisation eases ammunition sharing among allies. After the war in Ukraine, Western 155 mm stocks depleted rapidly and demand hit record levels. Firms with production capacity came to the fore, and ARCA has played a role in meeting that demand. Janes reported that Turkish ammunition producers plan capacity increases to serve Europe’s growing needs.
