D class TB (CSA):
Commissioned in 1892, the three ship D class continued the Confederate Navy’s progressive refinement of their torpedo boats.
These ships were 170 feet long overall and displaced 183 tons. They abandoned the bow mounted torpedo tube and ram-style bow of their predecessors for a conventional bow and four swivel mount 18” launchers firing to port and starboard. The gun battery of two 6-pounders remained the same as in the C class. Two triple expansion engines producing a total of 1,980 hp drove these ships to a top speed of nearly 24 knots.
After entering service, the new torpedo boats, designated as
D.1 to
D.3, were very active in the Atlantic and Caribbean, and also served in the Spanish-Confederate War where they formed an escort for the slow and vulnerable
Virginia class monitors. In a battle off Cuba in October of 1895, the CSS
Louisiana, accompanied by the
D.1 and
D.3, were attacked by a mixed force of Spanish gun and torpedo boats – which resulted in the sinking of both the
Louisiana and the
D.1, with her sister-ship severely damaged in one of the only decisive victories for Spain in the conflict.
After the war ended in 1897, the heavily damaged
D.3 (which was recalled after the battle and saw no further action) was immediately decommissioned and scrapped, while the
D.2 soldiered on until 1912 when she too was retired.
E class TB (CSA):
The four-ship E class represented the first major change in Confederate torpedo boat design although still drawing some features from previous classes.
They were 180 feet long overall and displaced 207 tons. Armament remained the same as on the D class but propulsion was significantly improved with not only a triple-shaft layout, but also the first use of quadruple expansion steam engines. With a more hydrodynamic hull the new ships were designed for a top speed of 26.0 knots but bettered that in service – CSS
E.2 achieving 27.5 knots on trials for example.
Designated as
E.1 through
E.4, the class was laid down during 1894 and commissioned two years later. They were popular with their crews and considered quite successful. They joined the CSN fleet for the final year of the Spanish-Confederate War and only saw limited action, emerged from the conflict unscathed.
The class remained in service after the war, and was scheduled to be retired around 1916, but in late 1911 the Confederate government was approached by Chile with an offer to purchase the entire class. The ships were formally decommissioned from the CSN in 1912 and transferred to the Chilean Navy where they served for another fifteen years before being retired.
F class TB (CSA):
The last Confederate torpedo boats to enter service, the F class continued the design established by the E class and together, were the progenitors of the first CSN destroyers.
Virtually identical to the E class save in length (190 feet overall) and displacement (232 tons nominal), the F class used the same armament as the E’s but were able to carry reload torpedoes for the first time. Two 18” Whitehead-type torpedoes were stowed on deck between the lifeboats, and a small collapsing crane to aid in loading was also carried. The same triple-shaft propulsion system as the previous class was retained, resulting in top speeds remaining right around 27 knots, although range did noticeably improve.
Five ships of this design entered service during 1900;
F.1 through
F.5, and all served in the Atlantic fleet for their entire service lives where they performed well. CSS
F.4 ran aground in the Florida Keys in 1903 and was declared a total loss, but the rest of the class remained in service until 1920, when they were decommissioned.
Next up: Yankee torpedo boats and some early destroyers.
Cheers!
