That being a Serbian rocket, which would suggest a purchase and/or manufacturing in Pakistan under a licence or transfer-of-technology agreement.
The Serbian industry has many land forces solutions. Expanding its artillery portfolio, Yugoimport-SDPR showcased its new 400-mm diameter Sumadija artillery rocket, which can push a 200-kg warhead to a range of up to 280 km. The Sumadija appears to be similar in concept to the Israel Aerospace Industries Long Range Attack Missile (LORA), albeit with a lighter warhead (versus the LORA’s 570-kg warhead).
The 400 mm Sumadija correctable rocket is 8.25 m long, has a total launch weight of 1,502 kg, a 889 kg solid motor, and a 200 kg unitary high-explosive/fragmentation warhead fitted with a proximity/impact fuze. Its minimum and maximum ranges are listed as 70 and 280 km respectively. As with a 122mm Grad, Sumadija uses wrap around stabilisation fins that pop out after it leaves its launch tube, but it also has pop out steering fins on its nose that enable it to correct its course using an inertial navigation system (INS).
The MoDP also inquired about the extended-range version of the 122 mm Grad-2000 rocket, which has a range of up to 52 km, which is deployable through multiple-launch rocket-systems (MRLS).
The inquiry in the Grad-2000 also indicates that the Army has far-reaching artillery modernization plans. While Pakistan Ordnance Factories (POF) manufactures 122 mm rockets, the Pakistan Army’s needs have evolved to require extended-range and, potentially, precision-guided rockets.
Besides Yugoimport-SDPR, the Turkish munitions manufacturer Roketsan is also offering its solutions (
