The Mk-55 "Thud" Liquid Fuel Engine is a liquid fuel rocket engine which does not attach at a node but rather to the side of other parts, typically a liquid fuel/oxidizer tank.
Usage
The Mk-55 is a liquid fuel engine with thrust vector control that allows efficient control of the rocket during descent and landing. The Mk-55 is fairly low-thrust. This is offset by its comparatively low weight, however. The engine has a TWR comparable to the LV-T45.
The low thrust and radial mounting makes a single Mk-55 unsuitable as a main engine on most lower stages, but it can be used to augment other engines. A common use of this engine is in lander designs, as it eliminates the need to have a vulnerable engine in an easily-damaged position. The Isp of this engine is adequate, being 275 s at 1 atm and 305 s in vacuum, not far behind the LV-T30 and LV-T45.
Additionally, landing legs can be added to these engines. This is an advantage shared with other radial engines: the LV-1R, the 24-77 and the O-10.
Like the LV-1R and the 24-77, this engine has the highest gimbal range at 8 degrees.
