Hi
He162 mounted 2 MK108 30mm cannon with 100rpg
or it could be fitted with 2 MG151/20 with 120rpg. The wing snapping problem was only on the prototypes, and the very few production types did not have this problem. He162 shot down 1 Tempest in the last few weeks of the war. It was also fitted with an ejection seat. It had very good control harmony and an extremly high rate of roll even over 400mph. Its major shortcoming was range/endurance.
Ta183 is something else entirely, and is a plane whose potential performance if actually built would not have been betterd until F86/Mig15. And yes the Mig15 was based on the Ta183, yes I said based. Mig15 was based on Ta183.
As for its armament the earliest ones were to be fitted with 4 MK108 cannon, but there was provision for mounting the new series of revolver cannon the MG213 20/30mm, these weapons had rates of fire in excess of 1000rpm and had higher muzzle velocity compared to MG151/20 and much better than MK108. MG213 was ready for full production in summer 45. The post war British 30mm ADEN cannon was directly based on this entirely new German type of cannon, as were the French DEFA and US Pontiac M39 20mm cannon, which IIRC was the 20mm cannon fitted to late F86, F100, and USN F8 Crusaders.
Rhurstal/Kramer X-4 wire-guided AAM had a range of several kilometers, generally between 2 and 3.5km . It carried a 44lb warhead, which could be set off by the pilot, a contact fuze or aucustic fuze. This weapon was in production at the end of the war, but certainly not in regular combat use. However, several Fw190 were fitted with the missles and associated control equipment in fall and winter 44/45 to combat test vs US bomber formations, I can find no information on how they did in those tests.
