The Ruhrstahl X-1 (Fritz X) was a glide bomb. Designed and developed by Ruhrstahl AG in 1943 under the leadership of Dipl.-Ing. Max Otto Kramer.

The Ruhrstahl X-1 was known by a number of different names, Ruhrstahl SD 1400 X, Kramer X-1, PC 1400X, FX 1400, Fritz X. This weapon was intended to be deployed against armored ships such as heavy cruisers, battleships. Dipl.-Ing. Max Otto Kramer had been experimenting since early 1938, with remote control freefalling bombs and in 1940. Kramer joined Ruhrstahl.

The Ruhrstahl X-1 (Fritz X) had four centrally mounted stub wings and the box shaped tail unit it also had a pointed nose which greatly increased its aerodynamic properties. the preferred release height for this missile was 5,500 m but it could be released at a height of 4,000 m and released approximately 5 km from the target of course visibility needed to be good as it was operator controlled via the Kehl-Straßburg system, the Fritz X could penetrate 130 mm of armour plate. The Ruhrstahl X-1 (Fritz X) was controlled by the operator in the carrier aircraft using a radiolink Kehl-Straßburg (designed and developed by Telefunken) the operator had to keep the target in sight at all times, to aid the operator in this a flare was ignited in the tail of the bomb so it could be seen from the carrier aircraft. The launch platform was a Do 217 however. It could be risky launching a Ruhrstahl X-1 (Fritz X) because the carrier aircraft had to decelerate before launching the missile as well as flying on a steady course right up until the missile hit its target, which left the carrier aircraft vulnerable to enemy fighters also there was a possibility of the missile becoming subject to electronic countermeasures.

The Ruhrstahl X-1 (Fritz X) was first used operationally on 21 July 1943 by III./KG 100 flying Do 217 in a raid on Augusta harbor in Sicily
