This appears to be the last surviving chapter of a series of classified training films made for the Royal Navy in 1943, detailing the workings of radar systems in a variety of roles, including search, anti-aircraft and fighter direction.
Titled "RADIOLOCATION (RDF) PART 7 : Operational use of Type Nos 273M and 284M in a cruiser", the film walks viewers through an unnamed Royal Navy Town Class cruiser's new surface gunnery radar technology and techniques.
It explains the abilities and roles of the associated radar sets, but also demonstrates the command network established aboard the ship to effectively apply this new technology to gunnery rangefinding and control.
This training documentary was produced by the Admiralty in conjunction with British Thomson-Houston (B-TH) - a British engineering and heavy industrial company specialising in naval electrical equipment, based at Rugby, Warwickshire, England.

There is so much there that is different from today's navies shown on that Town class: 1. Sound tubes in lieu of electric intercoms, 2. Paper for the plot with an anolog course computer, 3. All the radar antenna being manually turned, 4. Direct optical rangefinder directors with add on radar, 5. An open top bridge, 6. No AIC/CIC on a cruiser, 🤯 7. No plane position inicator (PPI) scopes anywhere. It is amazing how much the RN advanced between 1943 and 1945, technically.

This is the voice of Alvar Lidell during the Second World War his voice became famous reading of news for us . Lidell made the announcement of Edward VIII's abdication in 1936. On 3 September 1939 he read the ultimatum to Germany from 10 Downing Street and then, at 11 a.m. introduced Prime Minister Neville Chamberlain . who told the nation that it was at war with Germany . Called up in1943 he reported for duty with the Royal Air Force in North London as an intelligence officer . Spending some time at Bletchley Park. In1946 became chief announcer of the BBC Third Programme . For us he was the voice of the BBC on the radio , this was long before we had TV .

Fascinating. Install;ing new radar sets to existing ships must have posed some interesting problems - where to locate them, how to route all the communcaton channels, how to integrate them into a functioning system.

After several decades spent reading about naval gunnery, and several more years spent enjoyably watching yt, I wondered about the mechanics of it, with those how exactly they were able to range the ships, how the shots appeared on those antique cathode ray tubes and how overs/unders were determined? You've stolen a march on Drach, and fulfilled my questions. Thanks and Cheers to AuC and the RN of eighty years ago. Hmm, I wanted to say thanks and stand you to a watery Aussie Beer but I couldn't find you on Patreon?

Glad you liked it. But you can't compare making an old training film available to the hand-crafted detail Drach and Dr Clark put into their productions! As to patreon ... yeah, I dunno. Something about the concept doesn't fit comfortably with me. Perhaps I'm just too old for this newfangled gig economy I'm now a part of...

Keep RDF Secret. As if you could really explain how RDF works to someone that has no idea exactly what RDF even is by it's initials. It was actually what was eventually known as radar. And it would continue to improve and be able to shoot down enemy aircraft as well as surface ships. During WW2 most US Ships would be retrofitted with so much radar that some of their guns would be removed to keep them from being too top heavy cuz of the vast radar arrays that would be installed. But radar use during night time & times of bad weather would cause many victories for the Royal Navy before the US even became involved in the war.

I got this wild idea that the captain and executive officer of the uss Indianapolis never had his ship in this kind of readiness after he dropped off the bomb..1945 American radar could easily see the conning tower of a Japanese submarine at torpedo range..he also had the equipment in 1945 to receive radar signals that the Japanese submarine had coming from its radar

@benwilson6145 10 ай бұрын

I suspect that in a heavy sea the conning tower would be difficult to see in the clutter. It should also been in visual range

@randyjohnson6845 5 ай бұрын

@benwilson6145 ..there was no heavy sea..they were playing grab ass most of the day and night...get this thru your head..some how the captain knew what he was carrying and he some how knew that in just days or weeks the war would be over...they would have told rhe captain about the bomb..he wasn't eager to get back in the war..he acted like he was killing time instead of keeping high alert on a submarine..he could go 32.75 knots and be safe from torpedoes ..but he was dragging his feet..wake up...30 knots and zigzaging his ship is safe

So a single small screw fell out of the plot board of a Town Class cruiser during a practice shoot on the way to Okinawa. The results were ... humiliating. They had to disassemble the whole thing to discover the source of the fault.
