It would be able to put 550 tons of cargo in low earth orbit. The first stage had a single engine with a combustion chamber pressure fed by nitrogen, consuming LOX and kerosene and a thrust of 353 meganewton.
The second stage would have burned LOX and LH2, with 62 meganewtons thrust.With a diameter of 23 m and a total height of 150 m, the rocket would have weighed 18,000 tons.
