RAF Standard 250 pound Depth Charge

Postby sunderlandmr5 » Tue Sep 29, 2009 12:58 pm

Hi all

I have a question on depth charges used by the RAF in the Short Sunderland during WWII

I have this photo I found on the net, which i believe are Mark VIII Airborne Depth Charge in service 1942
Image

Then there are the ones on the Sunderland at Hendon which I have a feeling are the following
Mark XI Airborne Depth Charge in service 1942 (An improved Mark VIII with a concave nose to reduce ricochets).

I have some notes from a former RNZAF 490 Sqn pilot who was seconded to 270 Sqn RAF out of Jui in West Africa,
and he states Quote
"The depth Charges were like a drum with no nose cone, but fitted with a tail unit to stop it tumbling in the
air and kep it traveling forward as it sank.
" end quote
(Bumble if you read this it was the gentleman who showed you around NZ 4115 Q-Queenie at MOTAT, of interest in his notes he also flew a 270 Sqn aircraft Q-Queenie, photo can be seen in The Flying Boat Queen)

Does any one have any further information/photos/pictures? I tried the ones by Louis but it came up with bandwidth
exceeded???

Thanks

Alan

A drum with no nose cone? Like this one? :-

The above is the depth charge rack on the Sunderland at the RAF Museum, Hendon. I haven't got the details of exactly what is carried on it.

There were a variety of munitions carried by Sunderlands. The original 100lb anti-submarine bomb proved to be ineffective (especially after an Anson scored a direct hit on an RN submarine which reported no damage!). The depth charges were basically conversions of naval depth charges and IIRC came in both 250lb and 450lb varieties. I've got some detailed notes but not to hand right now - more later unless somebody beats me to it.

I've just spotted, in your photo above, the serial N9027 on the bomb rack. If it is Sunderland N9027 then she sank at Gibralter in a gale in April 1941. Which puts a question mark over the caption. They could be anti-submarine bombs??

OK, I thought that photo was familiar - it is from the Imperial War Museum collection and shows 250lb anti-submarine (AS) bombs: http://www.iwmcollections.org.uk/dbtw-w ... 0&FG=0&QS=
There were two types of AS bombs - 100lb and 250lb.

The IWM photo collection has some photos of 450lb depth charges being loaded:
http://www.iwmcollections.org.uk/dbtw-w ... 0&FG=0&QS=
and here:
http://www.iwmcollections.org.uk/dbtw-w ... 0&FG=0&QS=
and finally here:
http://www.iwmcollections.org.uk/dbtw-w ... 0&FG=0&QS=
which is this photo. Big thing the 450lb isn't it?
