Ta 183 was to be armed with 4 x 30mm cannons and a pair of AAMs [R334]. What was the Sabre armed with? From what I recall only 6 HMGs.
The metal needed to build better turbine blades was available but being used to build UBoat hulls. So build less Uboats and more Turbine blades.
Ah, the traditional disdain for the Browning .50 cal.
It is amazing that the clearly inferior 6 x .50 package somehow managed to muddle through against well, anything that was put up against it.
The short (far from comprehensive) list of cannon armed aircraft that the inferior .50 somehow squeaked past includes:
A6M
J2M
Ki-45
Ki-61
Ki-84
Ki-100
Bf-109
Fw-190
Me-110
Me-262
MiG-15
This does not include the several THOUSAND Japanese and German fighters and medium bomb/interceptors blown out of the sky by bomber defensive gunners who were also saddled with the M2 pop-gun.
It is truly amazing that the sky was not swept of the grossly underarmed P-51 (aka the best piston engines fighter of the war), F6f, F4U (Whispering Death to the JNAF), or Sabre (the best 1st generation jet fighter in the world).
I guess it isn't worth mentioning that pretty much anywhere in the West that a heavy machine gun is needed to this day, it is an air cooled M2.
