Jane’s is reporting that at Poland’s MSPO defense exhibition in Kielce, the new 155mm Diana tracked SPH was unveiled. Developed for a requirement by the Indian Army, the Diana SPH is a product of Konstrukta Defense and consists of a Slovakian autonomous 155mm L55 armed turret mounted on a Polish Bumar-Labedy UPG-NG tracked chassis. This turret was originally developed for use on an 8×8 wheeled chassis. According to the Jane’s article, the primary reason the Polish tracked chassis was selected was because it shares many common components with the T-72 main battle tank, a vehicle used by many of the potential customers for this artillery system. The UPG-NG vehicle was initially designed for the Krab SPH, but was dropped in favor of the SOuth Korean K9 chassis.
