To increase space for a unit commander, radio operator, and a FuG 6 radio transmitter with associated gear, the rotating turret and main armament of the Panzer I combat tank was removed. A tall, fixed superstructure was installed which contained space for the commander and radio operator to work, and a single ball-mounted machine gun was mounted in the front armour of this to give the tank a measure of defensive firepower. Fittings in the vehicle provided for carriage of 900 rounds of ammunition for the machine gun, which was either an
MG 34 or older
MG 13 in some examples, though in the field it was common for the gun and ammunition storage to be removed to allow for additional internal space. While room existed within this structure for map boards, paperwork and other kit required for operational command and radio operation, the vehicle's interior remained small, a factor leading to its rapid replacement by conversions of larger tanks. Six such conversions were made but meanwhile a new chassis was developed with offered more space for the modifications, and all production vehicles were made on this larger base. In addition to more space, the original tank's 60 hp 4-cylinder air-cooled Krupp M305 engine was replaced by a 100 hp 6-cylinder liquid-cooled
Maybach NL38TR to power not only the vehicle, but the newly installed equipment. The new chassis was more satisfactory and would go on to form the basis for the second mass-produced Panzer I, the
