German answer to the WAllies introducing the P-47 + DTs and Mustang Mk.X in June of 1943?

I don't see the He162 as a synonym for an 1-engined jet fighter
Germans will need to whip up something more docile, and perhaps using the other aircraft as part donors in order to speed up the production (besides the landing gear).

A problem is that the first generation "Class I" jet engines were maybe too weak to produce sufficient thrust for a single engine fighter that also carries sufficient guns, fuel, armor etc.? And the war is ending before Germany gets any of their Class II engines into service (HeS 011 etc.). Though if one insists on a single engine it should be possible to do better than the He 162 by integrating the engine into the fuselage. So maybe something like a slightly downsized Me P.1101 or Ta 183 with a HeS 30?

Germans did tend use lower pressures and so less temperature rise but if they are trying to fight in that 25,000-35,000ft area they really need to think about the intercoolers.

As I mentioned in "Jumo 222" and "DB 606/610" made in H16 form instead of being 24 cyl types - what gives? , for the 603L they did investigate intercoolers but determined they weren't worth the downsides of added weight and drag. Perhaps if they would have been using more boost like the Merlin they would have come to a different conclusion.

A lot of this depends how much of firepower is deemed sufficient. If just two cannons are okay (MK 108s and under), the Jumo 004 or the BMW 003 should've been sufficient, while a single HeS 8 might not be. Fuel carried - as much as the He 162, plus a drop tank? Armor for the back/head?

I don't mind the He 162 much, provided that it is made earlier and with a bigger wing, possibly a modification of the wing that is already in production.
My 'pet' projetcs are the Me 163 turned into a parts donor for a jet fighter (like some Lippsich designs), as well as the B&V P.211.02, a no-nonsense fighter with a straight wing and a lot of steel and wood used in construction.
HeS 30 looks great on paper - it was likely a missed chance by the Germans not to make more of the centrifugal jet engines as a whole?

We had an entire thread devoted to German centrifugal jets at Germany goes for centrifugal flow turbojet engines? !

Germans try the Yak solution

for the Meak-1015.

But short endurance and needed to glide when the engine flamed out is certainly draw backs.
