Please give Soapy and Chris all the support they deserve. The 'old' and the 'bold': Dixie and Pinta Despite having received his copies in the post last week, Dixie still spent considerable time looking at the books being sold by Stacey Edwards, a member of the RN Museum staff.

Fortunately, not everyone spent their time 'just browsing'. Dixie admiring Stacey's wares Right: Peter Harrison welcomes attendees Right: It can only bode well for future sales of the books which have already exceeded expectations.

A full set of photos is available for viewing or downloading here. It was also good to have along some of our elder brethren who, despite being in their seventies and eighties, always manage to come along and entertain us with their tales of yore.

It was also a pleasure to have along representatives from Divex, Northern Diver and Apeks. We ended up, of course, with the traditional singalong led by our very own Bill Kerr and our guests certainly enjoyed standing on the mess chairs under the watchful eye of Cdr Phil blasting out a few verses of 'Blowing Bubbles'.

The event went on until the early hours and everyone eventually retired having had a wonderful evening. A final thank you to the MCDOA for providing funding towards the dinner which was very much appreciated. I have attached two photographs.

The first is a pre-dinner group shot: Thanks for your continued support and efforts into making the MCDOA such a proud association to be part of and look forward to seeing you more often when I take up my next role as Chief of Staff to the FDS in August this year.To some extent, it's a For Want of a Nail setup when Played for Laughs.

The machinery, the structure, communications, sensors, weaponry will need updating and replacing and the hull . This book shows how the engineering and architectural aspects of submarine design relate to each other, and describes the operational performance required of a vessel.

The authors explain concepts of hydrodynamics, structure, powering and dynamics, in addition to architectural considerations that bear on the submarine design process.

For some good general notes on designing spacecraft in general, read Rick Robinson's Rocketpunk Manifesto essay on Spaceship Design Also worth reading are Rick's essays on constructing things in space and the price of a spaceship. For some good general notes on making a fusion powered spacecraft, you might want to read Application of Recommended Design Practices for Conceptual .

Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package of a nuclear weapon to detonate. There are three existing basic design types: pure fission weapons were the first nuclear weapons built and have so far been the only type ever used in warfare.; boosted fission weapons improve on the implosion design..
