The SSTV has 17 forward Hyperthrust Engines and 2 reverse Hyperthrust Engines on it and fully loaded has a delta V budget of around 20 Mm/s. With all 17 engines burning, it gets about 5 G's fully loaded also. There are pictures of it on this site, see the "Orbiter Pictures" thread about 5-6 pages (or more) before the last one.
It also has 60 standard nuclear thermal engines as a backup although using those it only has about 6km/s of delta V.
