WW1 Naval – Never Were Ships Britain-France vs Austria-Hungary

February 6, 2020

This scenario was designed to examine the tactical employment of several planned battleship and battle cruiser designs. See this post for the designs of the Austro-Hungarian Porject V and VI classes.

Winds WSW at 5 knots. Sea state 3. Visibility 12 NM.

With the A-H battle cruisers wrecked and the best A-H battleships damaged and in disarray, we called the game. The scenario was unbalanced, due in part to the powerful G3 and N3 classes and the weak (four gun) primary armament of the A-H battle cruiser class. We have yet to come to any conclusions about how to effectively employ divisions with differing speeds.

1/6000 Naval – 1905 British Scout Cruisers

January 5, 2020

These are eight scout cruisers completed in 1905 and modeled in 1/6000 scale.

From Conway’s All the World’s Fighting Ships 1860-1905, pages 84-85:

“These eight cruisers were intended to work in company with destroyers as scouts, to lead torpedo attacks and to back up their flotillas when attacked by enemy destroyers. The Admiralty provided a broad specification …. for a 25kt ship, with a 1-1/2 inch protective deck or equivalent side armour, shallow draught … 10-12pdr, 8-3pdr and 2TT. …[This] resulted in four sub-classes … that varied substantially in form, machinery and structure. … During 1911/12 they were rearmed with 9-4in guns.”

1/6000 Naval – Never Built US Torpedo Battleship Design

December 28, 2019

Displacement 30,000 tons
Waterline length 780 feet
Six 14 inch guns
Sixteen 6 inch guns
Eight 21 inch submerged torpedo tubes
Oil fired, 27 knots

 

 

 

 

WW1 Naval – Baltic Convoy 1916

April 7, 2019

This scenario was inspired by the Russian attack on a convoy of iron ore sailing from Sweden to Germany described in “After Jutland“, Chapter 6, pages 90-91. The Russian attack group of destroyers has a close cover force of cruisers and a distant cover force of dreadnoughts. The Germans expect the operation and counter with their own cruiser and dreadnought supporting forces.

Winds WSW at 5 knots. Sea state 2. Visibility 6 NM.

With only two Russian dreadnoughts left to face six relatively intact German dreadnoughts, we called the game. The convoy and most of the German cruisers had been destroyed, but the loss of the Russians dreadnoughts was a high price to pay for meeting the mission objective.

1/6000 Naval – Never Built Dutch Dreadnoughts

April 6, 2019

This is a Dutch dreadnought design from 1913, modeled in 1/6000 scale. Various designs were proposed from 1912 through 1914, as described in Warship International No. 4, 1988, No. 1, 1989 and No. 4, 1989. The 1913 quadruple turret design was chosen because it differed the most from contemporary German designs.

Normal displacement 20,700 tons
Length 169.2 meters
Eight 34.3cm L/45 in quadruple turrets
Sixteen 15cm L/50in casemates
Oil fired, 22-23 knots

The names were taken from late 19th Century Dutch cruisers.

 

 

 

 

1/6000 Naval – Never Built Ships

January 4, 2019

These are various ship designs from WW1 or shortly thereafter, modeled in 1/6000 scale. Many had little or no chance of being built.

La Motte-Picquet class French cruiser.

1917 Russian design for a Black Sea Battleship. The link has several 16-inch gun designs. Version 2 of the four variations by V.P. Kostenko (at the bottom of the page) was modeled since it was among the later designs (1917) and matches the drawings provided.

Austro-Hungarian Project V Battleship. Austro-Hungarian Project VI Battlecruiser. The last Austro-Hungarian battleship and battlecruiser designs were modeled.

German Post-Jutland Battleship Design Studies. Battleship study L20eɑ was modeled since it was selected on 11 September 1918 as the basis for the next German battleship (Dodson, “The Kaiser’s Battlefleet” page 126). Battlecruiser study GK4541 was modeled since it was among the last designs considered (Dodson, “The Kaiser’s Battlefleet” page 127) and since it was included in the Avalanche Press game “Jutland 1919“.

Tillman Battleships. Design IV-2 was modeled since it was the one presented to Congress early in 1917.

WW1 Naval – Oran 1914

December 2, 2018

This alternate history scenario was a confrontation between British and French ships in November 1914. The British were tasked with preventing the return of the French fleet from Oran to Toulon. The French were to get underway from the anchorage at Oran and get past the British.

Heligoland Bight – 1916

November 2, 2018

This Friday we played a fictitious naval battle set in the North Sea in 1916. The British attempt to sweep the Heligoland Bight to eliminate German patrols. The Germans are supporting their light forces with heavy ships. The scenario includes ships not actually available in the North Sea at the time.

We played for about 4 hours without a decisive result. The British had suffered somewhat more damage. In spite of a lot of torpedo fire from the light cruisers and destroyers, the only two torpedo hits were achieved by the Von der Tann and the Blucher.

Seekrieg 5 – Tsushima

May 26, 2018

This weekend the local HMGS-South group played a Russo-Japanese War naval game using the Seekrieg 5 rules. The scenario included battleships from the Battle of Tsushima.

The battle was fought in calm seas and hazy weather, visibility 12,000 yards. The lead ships started about 12,000 yards apart.

Japanese ships in a single line ahead:
Mikasa, Asahi, Fuji, Shikishima, Chin Yen

Russian ships in two divisions, each in line ahead:
Kniaz Suvarov, Imperator Alexander III, Borodino, Orel
Oslyabya, Sissoi Veliki, Navarin, Imperator Nicolai I

Crew quality was randomized, with the Japanese having a probable advantage:

Japanese:
1-20%       +1
21-80%    +2
81-100%  +3

Russian:
1-30%        -1
31-90%       0
91-100%   +1

The battle opened with the Borodino class ships firing at the four new Japanese battleships, the Oslyabya firing at the Chin Yen and the four Japanese battleships firing on the lead pair of each Russian division. The guns of the remaining ships would be out of range for several turns. The Japanese soon switched to firing their primary guns on the four Borodino class and their secondary guns on the older Russian ships. The Imperator Alexander III lost an engine room on the first turn, forcing her to leave the formation. That was the story for the rest of the battle, with the Russian first division taking most of the damage.

After 14 turns and more than four hours of real time, the damage was:

Russian:
Kniaz Suvarov                      3 tiers, speed reduced to 7 knots
Imperator Alexander III    1 tier, speed reduced to 9 knots
Borodino                               light damage
Orel                                        8 tiers, speed reduced to 11 knots,
–                                               no main battery, sinking
Oslyabya                               light damage
Sissoi Veliki                          light damage
Navarin                                  light damage
Imperator Nicolai I             light damage

Japanese:
Mikasa                                    light damage
Asahi                                       light damage
Fuji                                           light damage
Shikishima                             1 tier, speed reduced to 8 knots
Chin Yen                                 1 tier

 

 

Risikoflotte Risked – 1914 Naval AAR

May 5, 2018

This weekend the local HMGS-South group played a fictitious naval battle set in the North Sea in May 1914. The British attempt to destroy the German fleet in the North Sea bases. The German fleet sails to fight in the Heligoland Bight. The scenario is based on the British strategy of destroying fleets which may become a threat (Copenhagen) (also), and the German concept of the Risikoflotte (risk fleet).

Player briefings: Copenhagen 1914

Visibility 14,000 yards, improving gradually. Wind westerly at 8 knots. Sea state 3.

After more than four hours of play and 60 minutes of game time we called it a day. 5 British dreadnoughts were sunk and 2 were in a sinking condition. 2 German dreadnoughts were sunk and 1 was heavily damaged. The Germans could claim a tactical victory at this point but not a strategic victory.

This battle was played some years ago with an earlier version of the code.
