Ukraine replaces nearly half of faulty mortar shells
One of Ukraine's domestic producers of mortar ammunition has replaced defective shells from a batch of 100,000 caliber 120 mm shells under warranty. Here's the background on this issue and information on the affected shells.
According to the portal Militarnyi, a state supplier of mortar shells, which sparked a nationwide scandal in Ukraine in 2024 due to a faulty batch of 120 mm mortar shells, has addressed the problem. Notably, the Russian industry, which experiences fewer attacks, also faces challenges with maintaining ammunition quality.
From December 2024, the defective shells were systematically checked and replaced under warranty, with faulty units totaling 39,455 pieces. This represents nearly half of the production. It's also important to note that this exchange process occurred alongside the fulfillment of new orders.
The defects found included incorrect dimensions, improperly sealed rings, damaged propellant charge packaging, and flawed detonator caps. These issues could cause the shells to become lodged in the mortar barrel or fall off-target immediately after firing.
120 mm mortar shells — high firepower in a simple form
Artillery guided by drones is Ukraine's most effective combat tool, and mortars serve as a straightforward and effective weapon with a range of a few miles. Although heavy mortars like the 120 mm 2B11 Sani typically weigh about 440 pounds, transportation requires at least a motorcycle.
Such a mortar, using standard ammunition, can target distances of about 4 miles and maintain a firing rate of up to 15 rounds per minute. For opponents in open terrain, a barrage of shells containing approximately 3 pounds of TNT is extremely lethal.
Furthermore, many countries have developed mortars with longer barrels and extended range, using shells with rocket boosters or cluster warheads for a broader impact area. Among the noteworthy Western systems in Ukraine are the Polish self-propelled mortars M120 RAK, which are highly regarded by Ukrainians.
