The Panzer-Selbstfahrlafette II , or in full, 7.5 cm Kanone L/41 auf Zugkraftwagen 5t (HKp 902), was a half-track German tank destroyer used during World War II. Only two prototypes were built and sent to North Africa for troop trials. Neither survived the war. Design and description Development began in 1936 when Büssing-NAG was given a contract to develop an advanced half-track chassis with a rear-mounted engine specifically designed for use as a tank destroyer. Four prototypes of the HKp 902 chassis were built, two of which had Rheinmetall-Borsig's L/40.8 gun mounted in an open-topped, low-profile turret. The gun had an elevation range between −8° and +20°. It fired a K.Gr. rot Pz. (APCBC) shell with a muzzle velocity of and a Sprenggranate (HE) shell at . It carried 35 rounds on board. The armor protection, designed to be proof against armour-piercing bullets, was thick on the vehicle's front, and on the sides, on the rear, on the superstructure roof and on the belly. Service history The two prototypes were completed in 1941 and they were organized into a platoon for troop trials with Panzerjäger-Abteilung ("Anti-Tank Battalion") 605 of the Afrika Korps.
