Yes, these are clearly relatives!
I worked on a combat air traffic control system, run by a 4118.
It was a single CPU 18-bit machine, but with dedicated coprocessors
for radar video processing and a vector display system for radar
consoles.

Any relation to the HP4118?
I worked on 4118's in the USAF, but have never found any
into on them on-line.
Possibly. I recall seeing references to an older, 3118 machine. The
5118 is a dual processor, real-time computer, and was the central
processor in the JSS air defense system, connected to two HMP-1116
minicomputers which handled radar inputs, console displays, printer output
and hard disk storage, and a 3rd 1116 which handles the color status
monitor. The whole thing connects to a redundant system through one of
the 1116s. The 5118 had a wire wrapped backplane.
There's an article that mentions the 3118, 4118 and 5118:
