Norway Sends Ukraine Smart “Build-Your-Own” Grenades That Scale Their Own Blast Power

Ukraine has received a new type of modular hand grenade system from Norway, expanding its infantry capabilities with adaptable explosive devices.

According to Militarnyi on April 10, Norwegian defense company Nammo has supplied Ukrainian forces with Scalable Offensive Hand Grenade (SOHG) systems. Images of the grenades later appeared on a Russian Telegram channel, indicating that some units were captured on the battlefield.

The SOHG system is built around a modular design that allows soldiers to adjust explosive power depending on operational needs.

Each grenade consists of a compact cylindrical unit that can be used individually or combined with additional modules. Up to three modules can be connected into a single charge and equipped with a shared fuse, enabling scalable blast effects.

Technically, the SOHG is based on Nammo’s HGO 115-3.5 offensive grenade. Each module measures approximately 90 mm in height and 53 mm in diameter, with a total weight of around 140 grams. Depending on configuration, the explosive fill includes either 115 grams of Composition B—a TNT and RDX-based mixture—or up to 130 grams of PBXN-110 explosive.

The system uses a standard Nammo fuse with a delay time of approximately 3.5 seconds. Once activated, the ignition propagates through internal channels, allowing multiple connected modules to detonate simultaneously. While the design permits linking more than three units, the manufacturer does not recommend exceeding that number.

According to Militarnyi, the modular concept is intended to provide flexibility in combat, allowing personnel to tailor explosive output to specific targets or environments.

In parallel with military deliveries, Norway has also expanded its financial support to Ukraine. According to Ukrainian Prime Minister Yulia Svyrydenko on March 18, Oslo will allocate $200 million in budget assistance through the World Bank’s PEACE program, which helps sustain public services and macro-financial stability.

The contribution is part of a broader increase in Norway’s support, with total aid expected to reach nearly $8 billion in 2026, including investments in defense production and military capabilities.
