In the beginning of 1944, due to the difficult situation on the Eastern Front, the Luftwaffe was in desperate need of an attack plane with armament capable of destroying armored vehicles including heavily armored tanks (heavy tanks). In this situation, it became vital to arm Fw 190F planes with offensive armaments other than bombs. This was not an easy task, because the Luftwaffe had not developed weapon systems adaptable for mounting in light fighter planes. The only way to solve this problem was by trial and error until the proper armament could be find. First tested on the Fw 190F was the 280 mm mortar W.Gr. 28/32 with high explosive warhead. This missile was judged as unusable because of it's unstable and highly curved flight path that made it impossible to aim them into the targets. Next tested was the Panzerschreck 1 missile launcher combined into two three barreled units mounted under wings on ETC 50 or ETC 70 bomb racks. Each missile had a hollow-charge warhead. They were soon replaced by the more modern Panzerschreck 2 (PD 8.8) launchers combined in units consisting of two launchers with 88 mm missiles with hollow-charge warheads that could be fired individually or in salvos. Equipped in this manner, a Fw 190F-8 (W.Nr. 580383) was tested by Major Eggers at Udetfeld Air Base. The results obtained were satisfactory but there were also some disadvantages like the missile's short (137 m) range and limited accuracy. Despite this, in October 1944 a small number of Panzerschreck 2 equipped planes were delivered to service units on the Eastern Front.
In December 1944, the highly efficient missile Panzerblitz 1 (Pb 1) system consisting of six and, more often, eight R4M air-to-air missiles. They were adapted for tank destroying by mounting an 80 mm M8 type warhead for an armor penetration of up to 90 mm. Using the Pb 1 unit it was possible to destroy tanks at a 200 m distance. The only limitation was a maximum speed of 490 km/hr, not to be exceeded during missile firing (in a salvo of eight or in pairs). Up to February 1945 the Luftwaffe received 115 Fw 190F-8/Pb 1 planes.
The successor to the Pb 1 unit was the Panzerblitz 2 (Pb 2) unit. The main difference between them was the replacement of the M8 warhead by a hollow-charge warhead able to penetrate up to 180 mm armor. Also developed was the new missile system Panzerblitz 3 (Pb 3) with a 210 mm hollow-charge warhead, but it was not operational by the end of the war. The same situation applied with the AG 140 (Abschussgerat 140) missile system consisting of units with two 210 mm missile launchers different from Pb 3. The AG 140 system was tested on the following three Fw 190F-8 planes designated as prototypes: V78 (W.Nr. 551103), V79 (W.Nr. 583303) and V80 (W.Nr. 586600).
Apart from the previously described missile systems on the Fw 190F-8 plane, other weapon systems for ground attack were tested (e.g. doubled SG 113 A Forstersonde missile launchers mounted obliquely inside the wings directed downward. Firing performed automatically using Forestersonde magnetic field detection principle, when the plane flew over the tank. In October 1944, at the research facility FGZ (Forschungsansalt Graf Zeppelin) this device was mounted on the prototype Fw 190 V75 (W.Nr. 582071) and W.Nr. 586586 planes. In December 1944, system was also mounted on the Fw 190 (W.Nr. 933452). This system was found to have low accuracy, so development was abandoned shortly.
In June 1944, the development team commanded by Col. Haupt (Versuchsgruppe Oberst Haupt) prepared a special Gero II type flamethrower in three versions: A, B and C. The device was for attacking ground targets. In February 1945, preparatory work began, by the application of additional fuselage bottom cowlings, on a Fw 190F-8 to mount the flame-thrower. There is still no evidence that this project was realized.
Authorities decided that flight tests with the wire guided air-to-air Ruhrstahl X-4 (Ru 322) missile, probably with modified ground attack warheads, would be carried out on F-8 planes. For the test two prototypes were used: Fw 190 V69 (W.Nr. 582072), V70 (W.Nr. 580029) and three serial production F-8 planes: W.Nr. 583431, 583438 and 584221. During these flights the more modern Ruhrstahl X-7 (Ru-374) Rotkappchen and Henschel 298 missiles were tested as well. Tests were carried out with the unpowered BV 246 (LT 950) Hagelkorn flying bomb. Probably by Fw 190V20.
