Mike:
The Space Shuttle hit 5% if we count the Orbiter; Saturn V also put about
5% in LEO.
We are talking here about expendable SSTO, not reusable.

Multistage expendables don’t even have a 5% payload fraction. A reusable
SSTO hasn’t got a chance in hell of that.

Are you being a jerk on purpose or have you just not followed this
conversation?
Second stage of the Saturn 5 was also capable of expendable SSTO if
re-engined with SSME’s. Expendable SSTO has be technically feasible since
the late 1950’s; it simply hasn’t been economic. Nor will it be until 5%
payload fractions are achievable.

Wasn’t the former Titan capable of SSTO, assuming a practical “zero”
payload?
The Titan II first stage could even carry a token payload into orbit,
maybe 1t or so if you did things just right
Hi Henry,
Titan was a missile, how many 1t weapons did it take to orbit?
Or, Ascents did it perform SSTO?
