I agree with you.

The 1900 Galveston Hurricane devastated more than just the city. The Navy Yard was a shambles, and vessels tied up or docked for refits became casualties of the storm surge. The Corvette Guadalupe, docked for overhaul and reclassified as a light cruiser, capsized after hull openings allowed her interior to flood. Her slip filled with water and she rolled over, a complete loss that could only be salvaged. The Gunboats Liberty and Louisville could not raise steam fast enough to get out of the harbor were wrecked in the shallow waters of Galveston bay. Just these three losses represented 25% of the Navy's Hull strength.

To replace the loss of capability from the Guadalupe, the Leon Class Light Cruiser was authorized in 1901:



Laid down in 1902 and launched two years later, she would become the class leader for follow-on ships to replace the oldest of the fleet: the Colorado class corvettes. The last of the sail/steam ships would disappear within the decade. The modern 6" guns and the 3" QF guns were the best available at the time. A full complement of end and broadside torpedo tubes were also fitted, in keeping with the practices of the time. Relatively fast at a top speed of 18 knots, they could keep pace in range and speed with the new cruiser Invincible, which the older Colorados could not.

Red, dude, welcome back!

She looks awesome! Well done!

You can use my Patrol Gunboat if you wish.

REDHORSE just Beautiful, beautiful, Ahhhh! did not know there were so many stars in my room!

Thank you all for the well wishes. It was a LONG year away and I am glad to be home again.

On with the story:

The 1900 hurricane also disrupted the Army's coast defense construction. Many emplacements had to be rebuilt or re-started at enormous expense. Competing with the Army's project was a Public Works program to raise the level of the island eight feet behind a concrete seawall. For the next ten years, coast defense emplacements were given second priority and were only completed after the associated part of the island was raised.

Internal to the Navy, there was much debate over many of the tactical developments of the previous twenty years. Big gun ships were well established and under no threat to change, but less expensive torpedo boats had been adopted by many navies to counter them. Initial strides had been made with submarines for similar purposes, but were much more expensive and dangerous to operate. Congress refused to fund either until the Navy made up its mind what it wanted to do.

The coast defense gap was the prime opportunity. The Navy offered to fill it with coast defense submarines, executing torpedo boat tactics from under the surface. Torpedo boat destroyers had been developed, but an effective counter to subs had not. The submarine crowd won out, and the same year the Leon Class was authorized two subs were contracted from the Electric Boat firm in the US:



Costly and tempermental, they were very similar to the American Adder Class, but slightly bigger. They were economical in terms of personnel, with crews of seven that did not risk exceeding the force cap of 1800 end manpower strength. But they were hazardous to operate - the crews were inexperienced and often were filled by rejects from surface fleet. There were more than one accidental sinkings when hatches were left open, and fumes from the gasoline engines were a constant hazard. But the tactics were proven, they could exit the harbor and were nearly impossible to detect when submerged until within range of their 18" Whitehead torpedos.

For a Navy that still intended its surface fleet for commerce raiding and limited fleet action, the subs were an ideal fit for coast defense against the larger vessels being built by or for less-friendly nations in the western hemisphere.

Great to see you back and on this project; and the cruiser looks emminently 'do-able'

Er... Are you sure, that 18 knots for the 1900-era cruiser is really enought? This is a speed of not-very fast battleship this era.

That's the most I can squeeze out of her dimensions realistically. Faster would mean bigger, which means more expensive. Much also depends on whether you are using reciprocating engines or turbines. Here's the Springsharp numbers for the Leon Class:

Like all engineering problems, she's a series of compromises. The Cruiser Invincible she was designed to follow is already over 10 years old. She's comparable to other vessels of similar displacement of that time.

First, Welcome back redhorse.
I like the Leon class very much and that little sub, well, it is awesome. Good drawings of craft that look very life-like.
Anyway welcome back and good to see you're working this project.
