Ship Classes

Postby MRCAcct » Wed Jan 16, 2013 11:37 pm

I see a lot of the following ship classes being used, but was wondering how people would actually define them in terms of what they're supposed to do, not so much as a general size. (Though I'm listing them in their approximate size rankings). ie: What makes a Frigate different from a Corvette; from a Destroyer?

Corvette
Frigate
Destroyer
Cruiser (general)
--Light Cruiser
--Heavy Cruiser
--Battle Cruiser
Battleship
Dreadnought

Monitor

Escort Carrier (while the Carrier part is self explanatory, 'Escort' don't seem as clear to me)

THe term Escort Carrier came in WW2 when the Allies built small, slower carriers on merchant ship hulls. These CVEs were used to escort convoys in the Atlantic and CVEs in the Pacific supported amphibious assults with their aircraft. The Allies built over a hundred of them...

Ah, words don't you love them. Ship classes change depending on setting. Take the Star Wars 'Star Destroyer' a dreadnought if ever I saw one :roll: . So really what they mean is up to you.

Historically the various terms have changed their meanings over time, with one era's Frigate is another era's Destroyer or in another a Cruiser. For example the term frigate had died out by the late 19th century and was reinvented post WW2 to describe a WW2 style destroyer while the term destroyer would more closely match a WW2 cruiser.

That being said I think there is some consensus, here is my take
Corvette - light and cheap escort vessel to guard convoys not expected to met enemy military vessels
Frigate - Heavier escort vessel rarely expected to be in a full battle (could also refer to a specialized escort vessel AAW or ASW for example)
Destroyer - Very heavy escort vessel used to escort battle line ships in battle (a general escort vessel if frigates are specialists)
Cruiser (general) General workhorse (historically tended to operate far from home base. A sailing era frigate)
--Light Cruiser - lightly armed/armoured vessel (most often found in foreign stations)
--Heavy Cruiser - more heavily armed vessel (capable of being used as battle line substitute)
Battle Cruiser - lightly armoured battleship
Battleship - the standard battle line ship able to both take and give out heavy damage
Dreadnought - A more capable battleship (historically late era battleships)

Monitor- A heavily armed ship which has little or no maneuverability/speed. (Historically used for shore bombardment)

Of course everybody will have their own take on this and a perfectly reasonable justification for it.

IMHO, regardless of setting, you generally have three types of ship which roughly correspond to wet-navy roles as follows:

Battleships - dedicated combat vessels, whose sole mission in life is to destroy the other guy's battleships.

Cruisers - multi-role vessels, with enough weapons and defenses to stand up to anything except the other guy's battleships, but not so much of an investment of resources that they can't be risked on exploration, scouting, or diplomatic missions.

Escorts - primarily intended to guard non-combatants from pirates and unforseen dangers. Tend to square off against their opposite number in fleet actions and essentially cancel each other out. Can be indispensible against unconventional threats (torpedo boats, submarines, etc.).

I also have made several different CR=50 Gunboats with 4 hul & 1 armor, speed 12. They are designed to charge into a battle and add their heary short-range firepower to a battle. 8-)

Beowulf is a follower of Jeune École. But we already knew that ;) . (and no its not an insult look it up)

The issue of classes of ship in the real world are influenced by many factors which starmada does not address, such as operational considerations, politics and resources availability. The CRAT DRAT are a measure of combat effectiveness ans SU is some measurement of size but ships are also impacted by finances.
Like the recent thread on fleet composition it all depends on the setting. If, as many do, you competitively design and test them in 'gladiatorial' combat then the 'correct' solution is very different from you a playing a campaign and you need a fleet were your dreadnought has to be in many places at the same time.

Actually, my fleets resemble the USA Fleet in WW1. I think our fleet had more BBs & DNs than cruisers in 1917.

The fleet I usually play consist of DNs that range in size from 49 Hull & 49 Armor to 43 Hull & 43 Armor, speed six.
They are escorted by DDs that usually have 10 Hull & 10 Armor, speed eight or nine. Theer are gunboats/PT boats with 4 hull & one armor, speed 11+ to keep the other side off balance.

I have designed a couple of cruisers, but just don't enjoy playing them much so I replace them with DDs. The only time they get used is in small battles. These cruisers have 22 hull & 22 armor, speed seven and CR from 300 to 340.

The CR of the DNs ranges from 700 to 600, and the CR of the DDs is from 150 to 200. Other than the lack of cruisers, I do bring balanced fleets, the number of DDs usually being double the number of DNs I bring, with some of the smaller ones too.

A follower of Mahan then sorry :? .

A WW1 fleet would not have cruisers in its battle line. Aside for the light cruisers squadrons at Jutland used for scouting the frigates of the sailing era and the attached light cruisers at Jutland were for communications, repeating flag signals from the admiral to their squadron. DN/BB/BC and DDs would have done most of the fighting.

Prompted by your hull sizes Beowulf, I've just done a very rough comparison between German, British, and US WW1 fleets and the displacement of a 'battleship' was about 30 times that of a destroyer. A destroyer of 10/10 should compare with a DN of 300/300! Hmmmmm.

Remember hull size =/= "displacement". A more appropriate comparison would be space units. Thus, a destroyer of hull size 10 (too big, IMHO, but for the sake of argument) would compare to a battleship of hull size 128. (1,197 SUs vs. 35,966 SUs).

I think it would be more appropriate to set your "destroyer" at hull 3. This would put your "battleship" around hull 39. Still far too big for my tastes, but as I've said before, my life with Starmada has been one long (losing) battle against hull size creep. :)

I was not suggesting battle ships should be bigger just thinking about comparisons. I once played a great per dreadnought game called Steam and Steel which had 1 hull space = 1000 tons = 1 destroyer! It worked really well with destroyer flotillas sheltering behind the battle line then charging though to deliver a torpedo salvo.

It does show that a person needs to decide on the 'period' they are 'modeling'. Deploying a flotilla of Arleigh Burkes would be ridicules and having a displacement of 9000+ tons they are quite large at a third of the displacement of a WW1 dreadnought.

So back to the original question what is a DD? :D
