Royal Navy recent history

A curious site with a lot of cruise books.

Perousing in the commisioning or cruise books you can sometimes find valuable or unknown data, but regrettably very few times (Recently I saw in a commisioning book of HMS Eagle she was equipped with a multipurpose Sonar 184 (also for torpedo avoidance) from the 1964 refit, and I suppose also HMS Ark Royal from the 1964 refit). These sonars are not listed in any database, and probably them were previously equipped with Sonar 132 or other passive torpedo avoidance sonar, as the other big British warships.

As example

The mention to the Sonar 184 in HMS Eagle (page 7):
