Vanguard class Corvette
« on: March 21, 2010, 10:53:03 PM »

This is an idea that came to me while participating in a discussion over on the CBT forums. Basically the Houses start building warships earlier than they did in canon. Got two more designs and other notes on my thoughts but this could fit nicely in an alternate scenario - be it a no Clan 5th Succession War or whatever your heart desires. Enjoy!

Overview:
The War of 3039 revealed much to the leadership of the Federated Commonwealth. Their inability to crush the hated Draconis Combine was bitterly disappointing but the role of ComStar was even more concerning. The Order’s increasing adversarial position combined with the Dragon’s renewed strength convinced everyone that further military development was necessary. Some began to push for the recovery of naval technologies that would make construction of combat jumpships a valued trump card in the deck of the AFFC. The scientific renaissance that followed the 4th Succession War made such an effort theoretically possible but there was opposition. Many remembered the destruction wrought by these behemoths and wished to avoid their inevitable rebirth as long as possible. Despite these concerns Archon Melissa Steiner and Prince Hanse Davion both agreed that a Naval Redevelopment Program was in the best interest of the Federeated Commonwealth.
Authorized in early 3041 the first step of this greater program was designated the Vanguard Project. This endeavor focused on the construction of a test bed class to further development of a future warship production. Initial research quickly identified the two largest obstacles faced by would be engineers – the manufacture of Compact KF Core and Interplanetary Drive. Each of these components posed their own unique complexities and challenges which had to be overcome. A few manufacturers were able to upgrade their facilities to construct Compact KF Cores but continuing difficulties with the construction of the massive fusion engines proved unworkable at least in the short term. Rather than continuing with that long term undertaking designers decided to use the massive Sunburst M-200L MegaDrive from the enormous Behemoth class Dropship on the smallest possible warship keel. This temperamental power plant would produce the necessary thrust to propel the design across a solar system.
   Luckily Tharkad Aerospace Group (TAG) was one of three facilities in the InnerSphere that still produced the sophisticated Sunburst MegaDrive. This coupled with the fact that Ioto Galactic Enterprises of Alarion were able to upgrade their facilities to construct Compact KF Cores dictated that production of these prototypes would take place within the Lyran half of the Federated Commonwealth. The great industrial strength of House Steiner was bought to bear in other areas, like capital grade weaponry, which had to be restarted from scratch. Davion scientific contributions were just as invaluable to the rapid progress of the Vanguard Project which overcame many complications. On February 9, 3048 the RX-78 slipped from Port Sydney Naval Shipyards and became the FCS Vanguard.

Capabilities:
   As a proof of concept vessel the Vanguard made use of many recovered technologies. Its diverse armament which is made up of a wide assortment of capital grade weaponry is clear proof of this philosophy. The smallest of these arms designers were able to include were four Naval Autocannon/10s. Their inclusion eased manufacturing concerns and ably demonstrated their capability despite criticism that the vessel should have included “larger” main guns. The mid-range capital energy batteries of four Medium NPPCs and eight Naval Laser-45s somewhat offset this lack of firepower that would have been provided by larger naval autocannons. However, they provided far better range and eliminated ammunition concerns. The diverse amount of missile launchers also gave the Vanguard superior striking distance versus other warships as well as smaller craft. Two Killer Whale Missile Launchers provided punch while four White Shark Missile Launchers furnished the Corvette with further stopping power. Two super accurate Barracuda Missile Launchers rounded out this first of its kind arsenal. Nearly seven hundred Double Heat Sinks effectively disperse the waste heat generated from ship operations and represent some of the most advanced technology included on the ship. One hundred tons of Improved Ferro Aluminum armor plating provides effective protection especially given the vessel’s long range arsenal. The ninety man crew of the Vanguard is augmented by a company of marines for defense as well as a wing of aerospace fighters. Five percent of the warship’s overall mass was reserved for cargo space as design tradition dictated. No docking collars were included because of its small size and their inclusion would have complicated the construction of its Compact KF Drive. Perhaps the most concerning problem with the Vanguard was continuing problems with its massive Sunburst M-200L MegaDrive. During their initial installation these interplanetary engines seemed to be a good fit. A few modifications necessary for their inclusion were hoped to fix reliability issues seen on the Behemoth class Dropship. This was not to be as the drive soon demonstrated the same trouble operating above 0.8Gs.  With the unimpressive thrust they were originally projected to provide these breakdowns were somewhat anticipated. The Federated Commonwealth expects to learn a lot from their operations good or bad and refine future production.

Deployment:
   The Federated Commonwealth authorized the construction of twelve of these warships. Eventually upgraded the Federated Boeing facilities at Galax joined Ioto Galactic in the manufacturing of these test bed vessels. Over the next six years ten warships (Harbinger, Exemplar, Sentinel, Trailblazer, Prophet, Avatar, Monitor, Pathfinder, Herald, Ranger) were built at both facilities. In early 3055 construction on the final Vanguard, the FCS Warden, was completed at Galax. As expected this prototype class soon became obsolete by larger restored designs and new technology that followed. They continue to make excellent training ships for the FedCom Navy not only in regards to technology but experienced spacemen.

Since the technology to build the compact KF cores never became entirely lostech you could start building ships much sooner. Bad armor and lack of cap weapons would reduce them to carrier barges but they might still be useful to have around for major operations.

Something like this:


Mass: 200,000 tons
Length: 350 meters
Sail Diameter: 600 meters
Fuel: 4,000 tons (20,000)
Tons/Burn Day: 39.52
Safe Thrust: 1
Maximum Thrust: 2
Sail Integrity: 3
KF Drive Integrity: 4
Heat Sinks: 840
Structural Integrity: 60

Armor: (200 tons standard)
   Fore: 28
   Fore-Sides: 25
   Aft-Sides: 25
   Aft: 28

Cargo:
   Bay 1: Fighter  (60)      6 doors
        Bay 2: Fighter  (60)      6 doors
        Bay 3: Small Craft (16) - 4 doors
        Bay 4: Cargo 46259 tons - 4 doors ( 5% spares, 20000 ton ASF support )

Dropship Capacity: 4
Grav Decks: 2 (95-meter diameter)
Escape Pods: 200
Crew: 750 incl 120 passengers
Weapons:
        40 x LRM20 w 48 rnds each
        20 LL
        40 mL
        40 AC10 w 50 rnds each
        20 PPC

I don't know CJvR. ComStar probably would have squashed such an endeavor before the 4th Succession War with some sort of sabotage campaign carried out by ROM. The Houses may have tried such a project during the Succession Wars and been stopped in such a fashion. The Gray Death Memory Core really let the genie out of the bottle overwhelming their anti-tech efforts. Too many fires to put out but you are right such an effort was likely tried before.

I have two more designs and notes for refurbishment programs to come. Both the new designs work on the same premise as the Vanguard but go different routes. The Draconis design I was thinking is 200k tons and engineered as a true Corvette. Think of it as the ultimate weapon or at least the attempt at it. The Kurita warship would be geared as a true line vessel - fast, well armored, and good firepower. Marik design is the largest at 300k tons but is engineered like your above submission. It isn't terribly fast and likely has long ranged weaponry along with a high damage threshold. However it is a carrier type warship with significant cargo space to promote trade and supply military operations.

Perhaps, but they didn't shut down the various new mech projects running prior to SW4. It is hardly more than a jumpcapable tripple Vengeance carrier, for guys who knows real warships it is on the level of the USN paddle carriers of WWII.

IIRC several yards in the IS never lost the ability to build compact cores so there isn't a single lostech component in the barge for C* to get upset over.

PS: 670 still very rare borderline experimental double heatsinks is somewhat pointless, the ship can easily get by with singles effectively free sinke since they are currently being ripped out of refitting mechs and ASF.

 I was under the impression the only thing the States forgot/lost was the ability to build the huge planetary drives needed to move around in system, not the compact cores or even the capital class weapons tho I can see them losing the ability to make the missiles. Kinda hard to call ur self a warship when U can't really move from the location u jump into with out a fleet of tug boats pushing you along hmmm..... That would give a new meaning to Battle Barge.

Yeah they did, but they did have the drive for the Behemoth 100000 ton DS. It should work just as well for accelerating a small WS as a huge DS.

As for a true battle barge, considering that 0.1g is enough to move around a system the idea isn't without merit in addition to the obvious advantage in jump point assaults.

Nice ship and really like the fluff attached to it, I'd say this was better than the heavier Fox from Canon

Only real failing is the lack of DropShip collars otherwise a refined fighter and a decent training craft.  The Fox on the other hand is more akin to a baby Potemkin than a true WarShip

Really, as long as there is an unbroken line of people calling themselves "Clan Nova Cat," it doesn't really matter to me if they're still using Iron Wombs or not. They may be dead as a faction, but as a people they still exist. It's not uncommon in the real world, after all.
