The GB/CB/1916 (Hood style)

I had this concept for a variant of the GB/CB/1916 design that would rather Hood-like with 9-16.5in/45 and 16-6in QF guns with a 32.5 knot speed. The thickest part of the belt is 12in and the ship uses "all or nothing" protection. The "look" is similar to the 36-knot ship, which is an intermediate type between the Repulse and the Hood.

A new version of the GB/CB/1916 fast battlecruiser photograph

I wanted to change some parts of this photograph. I just finished the job, although I keep making changes to it, if anyone has noticed. This is another attempt at a Springsharp design:

What was actually possible with the GB/CB/1912 Fast design

I originally wanted a displacement of 29,000 tons and 180,000 SHP for power. If we use figures close to those, we don't see 38 knots, but more like 34 knots:

The GB/CB/1910 Fast design

The GB/CB/1910 Fast design in the "Red Book" is a rather minimalist listing. I was, as always, extremely over-optimistic about how much displacement and power would be required. The ship is in the spirit of the original GB/CB/1905 design, but with much higher speed (38 knots). With Springsharp 3.0 Beta 3, we have the 38 knots. The ship has 4-13.5in guns and light armour. Back when this design was conceived, we always used oil fuel and all-or-nothing armour. This is the Springsharp report:

The G3 Battlecruiser as a desktop on your PC

You might have to make an adjustment, but this should work as your desktop, with it centered. Stretched will always work, but it will distort the picture.

My answer to Alt_Naval's G3 battlecruiser

I am a fan of the Alt_Naval web site. Alt_Naval was one of my inspirations in early 2005 to try my hand at ship photographs. Alt_Naval has a G3 battlecruiser photograph, but to my taste, it is too close to the Nelson and Rodney and not close enough to the G3 look. I thought that I could get closer, although my photographs has some rough edges.
