Frigate to be laid down in Q1 1925

New class of treaty compliant vessel. These are being rated as Frigates.

They are multi role ships. In peacetime they are to be used for training.

They are equipped to carry a seaplane but no catapult. In wartime they are suitable for escort and could be fitted for minelaying.

Nice drawing!
What scale did you use?

Thanks,

I think it's 2 pixels to a foot for the smaller combatants. The Escort cruiser is 1.5 pixels to a foot while the carrier is 1pixel to 1foot. All my drawings are vector based and then I rasterise them to show here.

Cheers,

Just about her is where you lost me!!

What program did you use?
BTW I'm the original technophobe!!!

MS Paint is a pixel-based drawing program. It means that you can't scale-up or scale-down drawings easily.

With vectors, all the points are in a constant position and you simply choose whatever scale factor you want.

Alt_naval uses Macromedia Freehand which is made by the same people who do Flash. I'd use it myself but the freeware version won't work on my computer.

When I first saw this design I was reminded of the 1930's era USN gunboats of the Erie class. They were the same length, almost the same beam. The had 6"/47 single mounts instead of the 5".

On a personal note - while in the USN I served aboard several DE's/DER's during the 60's and early 70's. These ships were 306' in length. I try to imagine all that armament on a ship not much larger. It is not too unrealistic - some DE's had 2 - 5"/38 mounts and it was proposed to add 1 additional 5" mount to make them better of NGFS.
But these ships were really cramped. More guns means more space for ammunition storage and handling and larger crews. Plus the designed crew numbers probably won't suffice in wartiime.

I admire small ships. But don't try to put too much into a single hull. You need room for growth - no ship stays in its original configuration and most changes add weight, and there needs to be adequate crew space both as designed and allowing for needed growth.,

John,

that´s good input.

Do you think an airplane could have operated from one of the ships your served on?

From what I gather only the U.S. tried carring planes aboard DD's, with the Fletcher class, but only three were converted to experiment with this idea. They were quickly converted back to the standard DD configuration, but keep in mind they were converted to include a catipult, and as such 3 additional converstions that were planned didn't go through due to the dissappointing results.

That aeroplane takes up quite a bit of room.

The Dutch Gunboat Van Kinsbergen was the model but the US Eire class is similar. The US ships had room for an aircraft but no catapult. The Dutch ship had 4- 4.7" was faster and but less armour. I've included the aircraft for the training value. Dutch DD of the 30's also could carry an aircraft.

John, good points and I've noticed the ability to overgun Springsharp ships. The some of the 3" AA would be cut for topweight and probably X mount if necessary. There should be enough accomodation - but that's a guess.

On a development note, Wesworld has the 1930 London era earlier so we are seeing treaty dodging ships in the mid 20's where the Eire class were mid 30's.

Cheers,

Most pre-WWII USCG cutters carried an aircraft sans catapult, even the Lake and Northland classes at about 1700 tons.

The USCG Treasury class cutters also carried an aircraft without a catapult.

Original armament was 2x5", 2x6pdr, 1x1pdr and the aircraft, all on 2350 tons, 327' x 41' x 12.5'.

Taney later carried the heaviest armament of her sisters, 4 x 5"/38s. I don't know if she could still carry an aircraft in this configuration, though.
