Thanks Bill!
What I also found in the 6 klbs range is the Isayev S2.720 engine used
in the Russian SA-2 SAM. It has a max thrust of 34 kN (7700 lbs) and a
mass of 48 kg (100lbs). This includes the turbo-pump, gas generator etc.
Not so bad for a 60 years old design given that the whole engine was
made of stainless steel because of the nitric acid they used.

What I can talk about is the 2000 lbf thrust (at 600 psia) LR-101
which weighes about 2 kg as a bare thrust chamber assembly and about
15 kg. as a ready-to-install vernier engine. Both numbers are far
heavier than would be the case for a fixed engine. Perhaps those who
have flown one can comment on as-flown weights.

Does anybody have an idea what the mass of Rocket Lab's Rutherford
engine is (with or without pump assembly)? Or any other engines in a
similar thrust range (5-6 klbs)
Thanks!
