Hi Bryan

Hope you are well?

250lb Depth Charge info

Here you go

DC 250lb Mk XI and XI* (Service)

https://3.bp.blogspot.com/-D7diWksP0ZE/ ... MkXI-w.jpg


Overall length: 54.8 inches
Body length: 37 inches
Body diameter: 11 inches
Tail length: 17.8 inches

Tail width: 11 inches
Total weight: 265 pounds
Charge/Weight ratio: 66%

Fuzing: Hydrostatic Tail Pistols Mks XIV, XVI, XIX, or Mk XX

Tail No: Mk III (Mk IV when using Pistols Mk XIX or XX)


Color and markings: Dark green overall,
1/2-inch red band near nose,
colored band indicating nature of explosive painted around body in front of suspension lug.


Body Construction: The body is a welded cylindrical case closed at each end by a cover which is welded on. The central primer tube is welded into an opening in the rear cover, and extends approximately half way through the body. Equi-spaced around the rear cover are three lugs, each drilled and tapped to receive a stud used for securing the tail to the depth charge. Two filling holes, each closed by a bung, are provided in the rear cover. The front cover is dished inwards to prevent ricochet.


Tail Construction: The Tail Assembly Mk III is simply a cylindrical drum open at both ends. A strengthening ring is welded to the front end and provided with three equi-spaced brackets, weakly riveted on, which fit over the studs in the corresponding lugs on the rear end cover of the body. The tail is strengthened by six circumferential corrugations. The tail breaks off on impact with water. The front of the tail has one large port for the fuze-setting control link, and two small ports to give access to pistol and valve unit when fitting the fuze-setting control link.

The Tail Mk IV is designed with arming vanes and a reach rod to arm Pistols Mks XIX and XX, which are of the air-arming type and are replacing the Tail Hydrostatic Pistols Mks XIV and XVI. This tail is constructed with a three-segment cone, to which are riveted three fins supporting the three-segment cylindrical strut. Three hand clearance holes are equi-spaced around the forward end of the cone.

Suspension: The Bomb Mk XI has a single lug welded to the case at the center of gravity for British aircraft. The Bomb Mk XI* has dual lugs welded to its case for suspension from US aircraft.


Explosive Components:
Filling: 175lb Torpex

Hi Bryan,

Glad to help, knowing that it's for NZ4115 at MOTAT makes it even
more so.

I will have to have a hunt for the Smoke floats/flares info, I'll see what I can turn up.

Hi Alan,

Yes, I thought that would ring a bell with you..!

Been working for the past 12 nonths behind the scenes on a massive Gallery to upload to SEAWINGS featuring their restoration of the Sandringham and the Sunderland with one of the guys there that has full access and a bloody good eye for detailed photos. It's building into the most detailed series I have ever attempted in order to preserve for the future scale modellers, enthusiasts and the like, views of these 'boats that they probably will never get to see again, in order that they can add usually unseen details and create minature masterpieces..!

Are you near there (?) or get over there at all..?

Hi Bryan,

I live about 10-15 minutes away from MOTAT (as the crow flies (and traffic)).

I try to make it there a couple of times a year - my Daughter loves to visit there also
more than anything to see her Grandpa's Sunderland.

I've had a good lot of opportunities to take photos (being there at the right time)
Here are photos I've taken, most of these are first time posting

Your right about modellers being able to build more accurately, here's a link to my
Special Hobby Sunderland Mk V (RNZAF MR5) Review and Technical build currently
underway on Britmodeller
