Hello again!

After I posted the Black Sea Fleet's dreadnoughts two years ago, it's about time for the other stuff (limited to what was still operational in 1914), starting in chronological order with the

Russian Battleship Tri-Svyatitel'ya

[ img ]

She was a near-copy of HMS Trafalgar and the last Russian low-freeboard battleship. Slow (16 kts) and obsolete as she was, she was considered well armed (4x 305/35, 8x152/35, 4x120/40 and over 30 smaller guns) and well protected (457mm belt made from Harvey steel) and still had some life in her in 1912, when the decision was made to completely rebuild her above upper deck level. She received a homogenous secondary battery of 14 - 152/40 guns and landed all smaller ones except two 47mm saluting guns. Her built-up superstructure was lowered by one deck and her military masts were replaced with pole masts.

In this guise, she gave sterling service throughout World War one. She changed ownership several times in 1918 - 1920, and everyone who had to give her up demolished her a little bit more. What was left was scrapped in 1923.

Next: Rostisslav

Another superlative drawing.
Don't know enough about these ships to offer detailed comments but knowing your research these are probably perfect.

-I hope that my springsharp figures have improved... If not, please let me know. I am trying to find excuses for using it here. A lot of ships come out of springsharp as being really wet and unstable, not sure if the program is like that or what. Also, I have no idea how to use the freeboard mechanics so I just kind of let the program auto-design the figures based on the dimensions I put in...

Hi everyone

and on it goes with the Russian Battleship Rostisslav:

[ img ]

She was a somewhat downscaled half-sister of the Baltic Fleet's Sissoi Velikiy, with smaller-caliber main artillery (4 254mm/40 guns), but stronger and better protected secondary batteries (8 152mm/40 guns in four twin turrets). She had a 406mm belt of Harvey steel, but was only good for 16 knots. All things considered, she was a well balanced ships, because none of her features were any more than mediocre. Unlike the older Tri-Svyatitelya, she was not significantly modernized. She landed all her 47mm and 37mm guns and her torpedo nets, and received four 75mm HA guns. A rangefinder was installed on the former fighting top.
