Title: Naval (Blue Water) Vessels
Post by: Gabriel on December 23, 2011, 07:45:55 AM
Hi I was going over my copy of TRO:3085 Supplemental . On page 18 The Manta and Moray attack subs. It seems they were made under contract for the CAAN regiments. So will they be included in a future update of the Terran Armed Forces? Also they stated in the overview that the SLDF had taken military specialization taken to the extreme. So maybe more Blue Water Vessels

Well I'll have to take a look at that Gabriel thanks. See if I have TRO3085 Supplemental, think I do. But yes nautical warfare is an edge I wanted to develop more for the Terran Republic. In fact my design thoughts on a Nautical SDS is sort of what the Word of Blake did with the Wyrm SDS Submersible Fortress (JHS Terra).

Hi I might have some ideas on that front. Do you mind if I make some vessels and other items for the naval aspect of the Terran Republic?

Sure Gabe lets jump in the water. Knock yourself out with some proposals for the Terran Republic Armed Services (TRAS). We already have two designs appearing in Fanbook 2 - Project Phoenix [Sea Wolf Fast Attack Submarine and Nautilus Ballistic Missile Submarine]. I'm really still looking for Nautical Support Vessels of this time. I'd also like to gather up all designs for Nautical (Wet Navy) Warfare that are in use at this time. Be they Terran or any other Human Sphere power.

I'd love to hear about the Wet Navies of all the Houses and the Periphery while we are at it. For the Terran Republic there are three separate nautical forces. The elite mobile nautical force of the TRAS would be part of the Royal Marines who are trained and equipped to fight in exotic settings. Quote from FM Terran Republic;

Quote
The Royal Marines uses any and all equipment that will operate in space (primarily). Obviously this alters somewhat the Royal Marines strategic organization from the Terran Army standard. Replacing the ground vehicle (tank) regiment in Marine units is a nautical or wet navy (i.e. Boats and Subs) regiment deployed to secure enemy held sea territory. These vessels help the Royal Marines fight in their second favorite combat arena, the sea.

These units would be deployed via Anchorage class Dropship (seen also in FM TR 2785) which is a Nautical (Wet Naval) Carrier capable of deploying a full battalion of nautical forces (36 Heavy Vehicles).

The bulk of the Republic nautical assets fall under the control of the Nautical Subcommand. Nautical units are the rarest armor forces working to secure large bodies of water on planet. Split into surface craft and submarines these units are usually static and are deployed on Terran worlds only with significant seas or oceans. As these units are planet bound they fall under Army Command which has authority over all atmospheric combat types. This has added to the service rivalry in the TRAS which is intense but friendly. Headquarters for the Nautical Subcommand is located in Portsmouth Nautical Base, Great Britain and as of 2785 its Commanding Officer is Lt. General Danielle R. Mandel.

Finally there is the Reserve Command which has any mothballed or surplus nautical units at their disposal. This could be significant as the SLDF was likely the largest user of such equipment and likely had the largest force. The Houses were likely too concerned with Arms Restrictions and rapid build ups to worry about such forces. Both Nautical Forces (Army/Line forces and Reserve) would be part of System Defense Forces (SDFs) of appropriate planets. Worlds with large bodies of water like Earth, New Earth, Keid, Carver, Fomalhaut, etc in the Republic. Given the difficulty in rapidly deploying such units they are more defensive in nature then offensive.

I also cleaned up the Nautical SDS Thread link below. What do you guys think of just using the Wyrm as a Republic design? Our research pre-dated JHS Terra. In universe it is likely that the Blakist found such a Star League concept and built upon it whose to say it wasn't ours? ;D

Also of note from Project Phoenix;
Quote
Omega Castles are more intelligence facilities rather than dedicated military bases. They are the smallest Castles built by Terran military engineers and are typically the cheapest. Eventually these facilities will be built on every Terran world but current efforts are focused on constructing bases along the Draconis Combine and Free Worlds League border areas. Intended to be the last Castle so to speak they engage in passive intelligence gathering using advanced monitoring equipment to observe enemy forces operating in the system. In the event that this world is conquered by an enemy these listening posts would continue to function, tracking troop movements and resistance efforts to aid in liberation efforts. Staffed by observers from Military Intelligence they are trained to not make contact with the outside world until a relief or liberation force broadcasts a specific request for information. Typically they are located in the most remote place in a system (i.e. underwater or on a desolate moon) with many different broadcast sites to throw off enemy detection.

I think this is an area where we can create something new.

If you want, I can help you with that.


The most important part for now is to define the different theories of use behind the wet blue navies.
I won't be at home until the 7th late at night but once there I can look at my different books and see if I can do something out of it.

And you forgot the smallest ships, the Silverback, Monitor...
Title: Re: Naval (Blue Water) Vessels
Post by: Gabriel on December 25, 2011, 09:28:10 AM
The Idea came from the Land based system so of course it is ours. Also thanks the proposals will be forthcoming.
Title: Re: Naval (Blue Water) Vessels
Post by: Takiro on December 25, 2011, 10:40:57 AM
Thanks Gabriel. Ice what do you think about the Wyrm?

I didn't forget the Monitor but since it wasn't available to the BTSD era I didn't list it. Irose and I went over the text when we were doing availability lists. It never gives an introduction date but implies a newer late 2900s to early 3000s design. However for sake of completeness you are correct. We should also include the Neptune as well for idea sake even though that clearly ain't around. Yup did miss the Silverfin / Silverback Coastal Cutters.

* Also forgot to mention the special quote from the Meabh class Heavy Cruiser (TRO Vehicle Annex pg 164). Seems to indicate that the Star League was home to some pretty impressive blue water fleets and designs.

Quote
Remnants of the Star League’s Golden Age when peace, technology and funds in abundance allowed for excessive military installations, underwater command posts are rare at best in the present. As a mix of technological marvel, perfect protection and constructed madness these bunkers were very safe and extremely vulnerable at the same time, demanding several interlacing layers of different protection methods, one of them being naval escorts for supply convoys.
While the standard SLDF cruisers performed admirably in that role, they quickly fell into disrepair after the fall of the Star League. Even more so than other top-notch equipment of that era, those ships needed extensive and costly maintenance due to their constant use in the aggressive saltwater environment. Such was that by the end of the First Succession War, the LCAF saw itself forced to organize replacements if they wanted to retain some kind of bluewater fleet—which at least most of the social generals who didn’t want to lose their “personal pleasure yachts” did.

Also some unit notes. I'd like to see some brown water coastal guards as well as blue water ocean fleets. Seems like Liao deploys their nautical formations in Home Guard units and the Lyrans changed them from national control to planetary control during the Succession Wars.

Post by: Ice Hellion on January 24, 2012, 01:48:50 PM
I just gave a good thought to it and here is what I think.

Standard theory of use for naval power will not be used here as you don't have to fight for sea domination when you are alone on a world (ie one government).

What use is there for the Blue Water navy?
- Defence of a world,
- Direct support of troops,
- Defence of trade routes,
- Fight against guerilla,
- Denying conquest of a world.

Depending on the world, the standard use will be a bit different but I think this sums it up quite well.
What do you think?
Title: Re: Naval (Blue Water) Vessels
Post by: Takiro on January 24, 2012, 04:22:36 PM
Well Ice I doubt the bestest Wet Navy could deny the conquest of a world but that could go hand in hand with the defense of a world. Subs might be the best as they can survive an awful lot you would think. I am looking for general ships that would be used across the worlds of an interstellar nation. So we are looking for the appropriate House Lord angle on this.

I should have been clearer.  :)
Denying means they participate to this mission, I know they won't be able to do it alone.

And if you remember my original question, I was trying to see if there was any specific doctrine of use for each House.
If they have a specific doctrine, they are more likely to build a Blue Water Navy along these lines.

Nothing yet established for nautical doctrines Ice. I imagine they resemble each Houses military doctrines. Steiner likes big stuff, Liao likes to be sneaky, etc.

I'm gonna look back through notes and canon sources to shed a little more light on this.

Question; As water becomes more important in the 3rd Succession War would these designs become more important or less?

I don't agree with that as when you look at our good old Earth, the naval doctrines are more or less dictated by the raw naval power and the main ships of each navy, not by national preferences (even the French Jeune Ecole roots are a little more complex than what a first analysis might let you think).

Water becomes the basis for the economy of the InnerSphere (replacing Germanium which KF cores are built from) as the 3rd Succession War drags on. As water is the basis for life and human existence in a scavenger economy this does make sense. It also gives us a better look at the worth and defense of H2O but do you risk its pollution by fighting in it? While not quite the same value in the 2800s it does provide some food for thought.

Oh and I'll repost known canon nautical designs for reference again.

Also see the Sea Skimmer entry in TR3026/3039- it was created by lyran social generals who did use them as personal pleasure craft.  But those are much smaller then the other ships of the LCAF.

I think it depends- If there is a purification plant or other valuable site along the coast I can see the use of a naval forces to defend it.  Otherwise I don't see keeping a bluewater navy to defend a freshwater source- it is probably to large- a dropship could land, load water an leave before your wet navy ships can get there.

Yeah, gonna disagree with this. H20 as the basis for the economy of the Inner Sphere (it's two words!)?!...

The scavenger economy of the 3rd Succession War is exactly that, scavenger. There is no pan-Sphere basis like Germanium was during the Star League era. No integrated, or uniform foundation outside of the C-Bill. Within the Great Houses, precious stone, minerals, metals, anything could be the local basis for wealth. It's why we see so many raids for commodities during the long years of the 3rd SW.

Local commodities dictate their relative importance. A water world like Carver might have an abundance of bluewater ships, except they're not protecting the water, but the tidal power plants and water purification plants. As Irose mentioned, makes no sense trying to protect a large water source in the age of DropShips.

I think the authors exaggerated.
As for the Lyrans having heavy units, is it because of their national preferences or because they have the economy to build them and these units look more efficient than the smaller ones?

Yeah, gonna disagree with this. H20 as the basis for the economy of the Inner Sphere (it's two words!)?!...

is too weird as it depends on the planet.
Is water supply of lower quality and less available than during the Star League? Yes but this is all.

But this is a good question: what do the Successor States fight over? Planets? Raw Materials? Factories? People?

Today the relative lack of differences between classes and sizes of ship across most nations means that all doctrines are more or less the same, but this wasn't true in the between-the-wars period of the 20th Century, or even during the Cold War. 

The 1930s French Navy, for instance, focused on fast, heavily armed (but not necessarily well-protected) ships, as it anticipated deployment in a series of fast raids or counter-raids in the Med or anti-raider work in the Atlantic, and this mentality shaped the kinds of ships it purchased (few aircraft carriers or cruisers, a relatively large number of battlecruisers and fast battleships, lots of very large destroyers).  The Italian Navy anticiapted a lot of convoy escort work in the Med, and so had a large number of cruisers.  The Royal Navy had convoy escort on its mind everywhere, and so it had scads of weak light cruisers and light carriers, but also a powerful (if slow) battle fleet.  The USN had notably larger fuel tanks on its ships (even destroyers) because of the much greater ranges at which they needed to operate from major bases. 

Today's navies are much less varied.
Title: Re: Naval (Blue Water) Vessels
Post by: Takiro on February 05, 2012, 12:25:02 AM
Lot of good points. Irose, I shall add the Sea Skimmer. Sorry bout the oversight. And Ice I'd have to say the House Lords fight over resources which become increasingly industrial in nature as the Succession Wars drag on. However we are talking about habitable planets on which these resources are located and again these worlds increasingly become more about the amount of water they have on them. A key for habitablility. So it is in this fashion we speak of wet navies.

Halvagor makes some good points and I think as the 1st Succession War breaks out the blue and brown water fleets of the InnerSphere are not that different. I believe the Meabh class Heavy Cruiser (TRO Vehicle Annex pg 164-165 - 10,000 tons - Lyran introduced 2807) points to Star League vessels that the Commonwealth had to replace twenty years after the war began. This could indicate a somewhat limited number of generic craft that could perform their patrol duties on worlds throughout the InnerSphere.

Thoughts?

Agreed that it doesn't invalidate your point, Ice, but it shows that your argument isn't the only one around.  The role of the wet-navy ships in an era of interstellar combat is really only limited to the imagination.  Multi-purpose ships are almost a requirement, because there's the most incentive for that from a centralized production standpoint, and we're constantly led to believe that centralization is the way of the Inner Sphere (partly because of FASAnomics, but it's also just generally easier on the developers and game-balancers).

There are two ways I would handle this, thinking from the Star League/Great House perspective.  First, modularity; the USN is already experimenting in this with the Littoral Combat Ships -- unimpressively to date, but that doesn't mean the idea is necessarily unsound.  Alternately, have combat be the secondary element for ships.  This is a much older concept in naval architecture, going back to wooden sailing ships which could be either combat ships or trading ships (such as the Vikings).  So make ships which have more practical uses, such as Coast Guard search-and-rescue ships, ocean-going science/research ships, cruise ships, and the like which either have a moderate armament at all times (like USCG ships traditionally mount) or which can be relatively easily converted into proper (or improvised) warships when/if the need does arrive.  The Imperial Japanese government in the 1930s would underwrite passenger cruise ships so long as the naval architects who designed them took into account conversion of the ships for military purposes in the event of war, and this is the origin of the IJN carriers Jun'yo and Hiyo. 

Since the development of the "support vehicle" class we're finally presented with a series of mechanics that allow for proper-sized wet-navy ships; sadly, the ridiculous restrictions on long-range firepower still greatly limit the utility of such vessels.  But any major port city in the Inner Sphere ought to have some sort of naval protection available to it, even if the ships are normally kept in reserve, rather than out at sea.  If nothing else, they provide protection from hovercraft trying to invade cities from the sea, and could realistically (if not yet in the rules) detect and interdict 'mechs trying to infiltrate along the ocean floor.

Do I think that this makes the most economic sense for a defense force in the 31st (or 28th) Century?  Nope; but then, neither do 'mechs; all the money and effort spent on 'mechs and tanks would be more effectively spent, per the game mechanics, on assault droppers and aerospace fighters, and not limited ground forces.  But no military is actually about what makes the most economic sense, least of all one in a game about giant robots and FTL warfare.

Post by: Takiro on February 16, 2012, 10:12:24 PM
Well I wanted to enter in two more canon designs which really shed more light on the state of nautical forces in different eras of BattleTech. The Sea Skimmer as Irose pointed out is a design which I over looked when putting together my original list however the first paragraph from the overview says a ton.

Quote
After the Exodus era the wet navy all but vanished.  Each newly colonized planet had only one government and so had no need to build a wet navy to sink another government's wet navy.  Nor could a colony world hide behind an ocean when invaded from space.

It would seem that the nautical forces of the InnerSphere were a luxury of the Star League era and when war came they were disbanded. Likely cannibalized into more useful endeavors rather than destroyed I would think. Troopers being mobilized as infantry with weapons and ammo going to other military arms.

It all really adds up if you read the canon design lead ins. See the second canon vehicle i missed the Mauna Kea Command Vessel. It lays out the role of the wet navy which Ice asked about earlier essentially a pirate hunting force deployed against raiders in economic vital yet remote ocean locations. Makes sense I guess cause Mechs and AeroFighters can really smash any wet naval force.

Factor in the difficult maintenance of sea going craft along with more pressing military concerns and you get the fringe military wet navy. Some worlds have more important ocean real estate to cover and deploy larger forces but that is the exception and not the rule.

Let me update that list once again.

It lays out the role of the wet navy which Ice asked about earlier essentially a pirate hunting force deployed against raiders in economic vital yet remote ocean locations. Makes sense I guess cause Mechs and AeroFighters can really smash any wet naval force.

It makes sense but for some designs it doesn't.
Can you imagine attack subs and ballistic missile ones being used against pirates?

Well attack subs make sense for local defenses. For example, say you have an important off-shore refinery, attack subs can provide surface and sub-surface protection from pirates and under water saboteurs. In this case, an attack sub fulfills two defensive roles, and can operate without interfering with surface traffic.

Ballistic missile submarines are strategic assets. They're pretty terrible (or a waste) for just about everything outside of their designated role.

Well if you have something like the Wyrm which is sort of a Ballistic Sub it is nice to augment your System Defense System. Subs like the Nautilus are more useful to attack a coast line probably in support of a land force but as a raider popping up here there I could see usefulness. Then there is a third type of sub to consider, the carrier.

Still subs seem like the best way to go to me because they have a natural defense. I imagine they are hard to detect and difficult to destroy at least without the right kind of weaponry.

How do you guys feel about surface ships? They seem very naked to me especially the larger ones. Their presence is hard to miss again the bigger they are would lead me to say is a disadvantage. Aerospace assets can hunt them with impunity.

You can stack some pretty serious AA firepower on the larger ships. Additionally, surface vessels are absolutely not designed for solo operation. They operate in fleets, stacking support roles and covering each others weaknesses.

Do you want a comparison in-game, or in reality?  In game, subs strike me as horribly limited and complex; the Star League may have fooled around with them, but their utility for anything other than all-out war is nonexistent.  Surface ships are better, but the ridiculousness of BT's weapon set robs them of everything which makes real naval ships awesome.
