This is an update/reboot of a series I uploaded some years ago.

The following couple of films, from 1959 show the principles and operation of the Navigation and Bombing System (NBS) Mk1 analogue navigation computing system as fitted in the RAF’s Valiant, Victor and Vulcan aircraft.
This worked with the H2S Mk9 Ground Mapping Radar to produce the navigation and bombing solution for these aircraft.

I 1st came across this system when I joined 617 Sqn in 1970 but it wasn't until 1974, after further training that I started to get to know and love this equipment.
I actually taught this, though without the bombing component at RAF Marham in the mid 80's finally saying good by in 1988 when I moved to AI24 Foxhunter Radar development.

As you watch these films you may see where my love of analogue systems comes from.

Part 1. Navigation Computing

Part 2. Bombing Computing

So grab a brew, sit back and enjoy.
