The 105 mm howitzer with a range of around 11 kilometers is known for reliability, speed and accuracy.

The Defense Acquisition Program Administration, the country's arms procurement agency, launched a project in 2015 to develop the evolved 105 mm howitzer in partnership with Hanhwa Techwin, a local defense firm.

"It was assessed as fit for combat by meeting all required operational capabilities in a recent test," DAPA said. "Accordingly, mass-production will begin in 2018 for use by our military units."

It uses an automated fire control system and an advanced GPS device, enhancing the shoot-and-scoot capability.

The number of operating personnel will be reduced to five from nine for each existing 105 mm towed howitzer. (Yonhap)
