If you meant Grand Slams

Because with a 44,000lb bomb load (two Grand Slams) it would never make 33,600ft

Aren’t you shifting the Goal posts?

I asked you why you previously said a B-29 could not reach 18,000ft. You still have not answered that question yet?

With two 22,000lb Grand Slams mounted near the wing roots, the B-29’s Zero Fuel Weight (ZFW) would only be 115,360lb.

If you add fuel to reach Farge, Bremen (282sm) and return (say 600sm +Res) about 9,000lb more than sufficient for a mission from Norfolk to Bremen + return with Gross take off weight of 124,360lb. The B-29 combat ceiling climbing at at 500fpm is 36,550ft and 100fpm climb at the service ceiling of 40,000ft. One engine out ceiling is 35,300ft so why would 18,000ft be a challenge for an aircraft well below maximum gross weight?

The B-29’s Ceiling is based on maximum Gross weight less fuel burn. We are not even talking about a mission with full fuel.

Take off distance would not have been a challenge from RAF Sculthorpe’s 2,000m runway either.
