Developmental work on air-to-ground rocket projectiles has been authorised by the Air Staff. The design parameters for such weapons include a warhead diameter of 13cm and projectile weight of 20 kg, using solid fuel boosters. It is expected that the first such test units will be available early in 1942, and it is hoped that by 1943 such weapons will be available to supplement the ordnance loads of strike aircraft.

10,000 trainers! Could we have breakdowns of that figure? It seems rather high even if some of them are in quasi-civil use or others mothballed. Any historical figures to back that up?

Seems a rather rapid shift from piston to jet power.

Hrolf had put a lot of effort into MW and GM boost systems and no doubt engines like the Jumo 222 and 223, BMW 802 and other Daimler Benz types could fill useful roles within the next generation of piston aircraft.

are we going to see piston fighters like the BMW 802 powered fighter of 1941, the Ju 188/ 388, Ar 240, Me 265, He 277/ 274, Fw 191 as examples of the latter piston engined designs?
Quoted
lack of suitable alloys, development of said alloys etc etc.

It's hard to find many German patented alloys in this period, certainly Germany in WW has greater access to raw materials and there is reason to suppose that given greater access to raw materials it may develop its own Nimonic and Iconel type alloys, but that takes time.
Waving a magic wand and saying "oh yes its not an issue becuase I've got X amount of firms" seems a flawed arguement. While I agree in WW its possible for Germany to follow the British path there is a lack of proof OTL that it intended to and that Germany's firms would have gained all the answers anyway.

...but your comment "Well, I think I can dispose of the question of suitable alloys for the first generation of jet engines rather quickly" seemed to scoot over the whole issue by linking to a couple of adverts.

Four jet engines for two fighters and one bomber seems a little wasteful at this time. Who can say if the jet is going to be a success at this time? Yes it offers speed at altitde but serious question marks remain over reliability, time between overhaul, engine life, blade failure, fuel consumption, lack of suitable alloys, development of said alloys etc etc..

Great, thanks. That is going to be interesting. Number crunching at its best. Xo) There are so many source on that issue and the data varies a lot...
