Indonesia is reconsidering plans to acquire more Ukraine-built BTR-4 8×8 amphibious armored personnel carriers (APC) after issues cropped up during training activities.
After concluding initial training on the amphibious vehicle, Korps Marinir (KORMAR), the Indonesian Marine Corps, reported several problems, including the APC excessively trimming at the bow while immersed in water and operating at full speed.
Five of the vehicles were delivered to Jakarta in September as part of a deal with Ukraine state-owned defense manufacturer Ukroboronprom, as Indonesia sought to replace the 100 BTR-50PK APCs it acquired from Kiev in the 1990s.
One Ukroboronprom official told Janes in November, “After official acceptance we will talk about expanding technology transfers to Indonesia and about expanding the order…We know [KORMAR] has a requirement for another 50 vehicles. This could mean some of these vehicles are built in Ukraine followed by technology transfers and local production in Indonesia.”
The vehicle’s main weapon is a ZTM-1 30 mm cannon. It also features an AGS-17 30mm grenade launcher and a chemical, nuclear and biological filtration system.
