Design Challenge: SLDF 2780
« on: October 23, 2013, 04:10:23 AM »

With Amaris dead and the election of a new First Lord underway, the SLDF turns towards rebuilding. Admiral Janos Grec issues requirements for new designs of warship to be used to rebuild the devastated Naval Command, which is now reduced to less than a quarter of it's size fifteen years ago.

The desired classes are:

A. Battleship for use as command vessels in fire support and line squadrons
Requirements: 3/5 thrust, onboard HPG and quarters for command personnel, LFB not required
Submissions: Royal Sovereign, Phoenix, Warspite, McKenna II, Texas II, Dreadnought II, Majestic

B. Battlecruiser as command vessels in pursuit squadrons
Requirements: 4/6 thrust, lithium-fusion battery preferred
Submissions: Richelieu, Crusader Type 44, Tribal, Admiral, Intrepid

C. Heavy Cruiser for use in fire support and line squadrons
Requirements: 3/5 thrust, important to keep cost down for mass production, cargo capacity of at least 100,000 tons
Submissions: Corsair's heavy cruiser, Centaur, Fort

D. Frigate for use as a convoy escort and for fire support of ground troops
Requirements: good endurance, 6 dropship collars
Submissions: Normandy, St. Louis, Dart II

E. Light Cruiser to fill out pursuit squadrons
Requirements: 4/6 thrust, lithium-fusion battery preferred
Submissions: Naga II, Tribal

F. Destroyer as general purpose vessel
Requirements: low cost for mass production, diverse capabilities.
Submissions: Naga II, Peterson, Kansas City, Graf Spee, Pioneer, Lola III Mk XV

G. Light Carrier for use in patrol and escort roles.
Requirements: 4/6 thrust, low cost for mass production, good endurance, anti-dropship and anti-fighter firepower important, should carry at least 60 ASF.
Submissions: Corsair's carrier, Corsair's second carrier, Leonidas, Obelisk, Lola III

In general, it is preferred that designs should give consideration to the likely use of nuclear missiles of both the capital and fighter-carried scale against them and consider defensive arrangements accordingly. SDS drone systems are acceptable but if proposed then a human-manned command version to control them is also expected.

Bids outside requests: Reuben James, Ark Royal

My Naga II is hereby submitted for a Destroyer.

At 540,000 tons it is lighter than the Essex or Lola III, but includes a Lithium-fusion Battery allowing it to rapidly deploy while escorting the SLDF cruisers and battleships.  Even so, the price tag (~4.8 billion C-Bills) is roughly equal to that of the Essex and slightly more expensive than the Lola III.

Thrust is 4/6 with very heavy armor protection for its size (layout of 110 nose; 110 front L/R; 110 L/R broadside; 110 aft L/R; 97 aft) with 12 ASF, 2 small craft, and no docking collars.  The design carries a mix of capital and standard weapons (1 NAC-30, 7 NAC-20, 12 NL-35, 8 Light N-PPC, 2 White Shark, 2 Barracuda, 32 Large Pulse Lasers, and 48 Medium Pulse Lasers) with the White Sharks able to carry Santa Anna tipped missiles.

Fuel tankage is 14,400 ton, with ~54,000 tons of available space for cargo and spares.

Sure, it lacks the ability to engage targets at Extreme range (except for the 4 cap-missile launchers) but that isn't a major concern for an escort.  And, in close, it has solid firepower.

The carrier is intended to fill the Corvette role for now.

MA: your link appears to be dead. However based on your description, the Naga II is provisionally accepted as a candidate for the Destroyer role (although it's still a bit more expensive than desired) and also as a candidate for the Light Cruiser role (although it's very light for the role).

Well the old Naval Archive has many designs that may fit the bill. Plus Knightmare and Ice Hellion got a few as well. I'll gather a list of new Star League designs at the time of the Coup which might be able to be continued in this eventuality.

Designer's Note:
The reference to the Mckenna's "crankiness" in the fluff is actually supported by the battlespace rulebook. The maintenance requirements and average support points generated listed in that book (pages 59 and 63 respectively) indicate that the Mckenna is just shy of meeting its maintenance requirements and will as a result suffer on average 3 malfunctions a month. This baby on the other hand does just fine.

Overview:
Without a doubt, the SLDF Navy was the most powerful fleet to ever exist, and its battleship arm, close to four hundred ships strong at its height, was certainly the crown jewel.
However, there were some flaws in that jewel. In 2755, with every house hard at work building up its military as quickly as possible, the SLDF assembled a commission headed by Admiral Nicolas Martine (a veteran battleship commander of great repute) to evaluate the SLDF fleet and its ability to fight a prolonged war against the fleets of the other houses.
Though the commission concluded that the League fleet would ultimately emerge victorious in a simultaneous war against as many as four of the great houses, they did cite several "concerns" with the SLDF fleet, specifically its battleship arm.
The SLDF's principle front line battleships at this time were the Texas and Mckenna, and the commission found fault with both. The Texas was a massively armored and extremely reliable ship well suited to long stretches of continuous duty, however, she lacked firepower.
The far more numerous Mckenna, on the other hand, had firepower to spare. However, she was (in Martine's own words) "cranky and temperamental". The McKenna was a very complex war machine, and she acted like it. While a Texas outside of combat might suffer at worst one or two major system failures a year, a Mckenna endured on average three major failures a MONTH. This generally meant that the Mckenna was limited to a three or four month tour of duty before she had to return home, and frequently required days in a shipyard to return to full operation.
Though neither class was due for retirement anytime soon, with all of the great houses rearming, the decision was made to develop a new battleship that combined the best qualities of the Texas and the Mckenna, and which would (eventually) replace both craft.
A fierce almost eight year long design competition followed between the Hegemony's most respected shipbuilding firms. Every company in the Hegemony knew what gaining the contract to build the next generation of battleship could mean for them, and everyone wanted it.
Ultimately, the winners were what some in the corporate world regarded as a devil's alliance. Krester's Ship Construction and Blue Nose Clipperships, the builders of the current generation of battleships and fierce rivals, collaborated to produce a joint design, which was tagged the Royal Sovereign. This combination of Krester's technical skill with Blue Nose's massive construction capabilities was simply something no other firm could match, and the SLDF approved the construction of two ships for evaluation.
SLS Royal Sovereign was launched from Krester's shipyards in the Bryant system on April 7, 2766. SLS Royal Oak was launched at Mars eight days later.

Capabilities:
The Royal Sovereign combines the firepower of the Mckenna with the armor protection and proven reliability of the Texas.
The ship's main battery is composed of two-dozen heavy naval gauss cannons backed up by sixteen class thirty naval autocannons. This gives the ship firepower to match the Mckenna.
Mounted in the nose is a battery of twenty naval lasers. These weapons add little to the ship's actual offensive power, as they generate too much heat to be used in concert with the rest of the ship's weaponry (the Royal Sovereign has a very limited cooling system, a deliberate design decision meant to reduce maintenance requirements). The lasers do, however, give the capacity for low-level orbital bombardment, allowing the ship to function as a virtual artillery battery for ground troops without straying outside of the Ares Convention.
Backing up its considerable firepower, the Royal Sovereign has hangar space for a full regiment of aerofighters. In addition to augmenting the ship's offensive capabilities, the large fighter complement also allows the Sovereign to better protect itself against enemy fighter attack. This is important because the ten AR-10 missile tubes the ship carries, though on par with most of its contemporaries, do not provide adequate defense against aerofighters.
The Royal Sovereign and Royal Oak were originally meant to be equipped with lamellor ferro carbide armor, however, with the increases in naval production and with the periphery in open rebellion, stockpiles of the advanced armor were very low. As a consequence the two ships were armored with ferro aluminum armor, with plans to rearmor them after their trials period was completed. Even with the older armor, the ships could still match the armor protection of the Texas.

Deployment:
After a two-month shakedown cruise, the Royal Oak and Royal Sovereign began their evaluation trials in the Cartago system in the Federated Suns. The SLDF was greatly impressed with what they saw, and after the trials were completed, the ships were ordered to head to Terra for refitting with new armor in preparation for entering full commission. The SLDF in the meanwhile announced its intention to procure an additional fifteen ships of this class (replacing the few remaining old Farragut class battleships still in service), with even more planned in the future.
Unfortunately, this was not meant to be.
On December 27, 2766 the two ships were in the Nirasaki system in the company of the assault carrier Gilgamesh. The Amaris coup began in the Nirasaki system when Rim Worlds troops seized control of Nirasaki's SDS system and turned the system's Caspars against the SLDF warships in system.
In that nightmarish engagement, the Gilgamesh was quickly overwhelmed and destroyed, while the Royal Sovereign and Royal Oak barely managed to fend of their attackers and withdraw from the system. Eventually the ships made their way out of the Hegemony.
By 2772, the two battleships were assigned to the SLDF's Task Group Crusader, composed primarily of the few warships to make it out of the Hegemony intact. This fleet served at the forefront of Task Force Commonwealth's advance into the Hegemony, and took horrendous losses as a result. The end of the fighting had destroyed most of the fleet, including the Royal Oak.
The Royal Sovereign survived the war, though she was in poor condition. Nevertheless, the ship accompanied the Exodus and was mothballed upon reaching the Pentagon cluster, where she remains to this day. Given the massive amount of work that would be needed to restore the battleship, it is doubtful that she will return to service any time soon.
 
Designer's Note: I'm sure someone is going to raise the old complaint about naval gauss cannons, so:
24 heavy naval gauss cannon: 194,040 maintenance points
48 heavy naval PPCs plus the extra heat sinks needed to use them: 250,700
maintenance points
48 NAC 30 plus the extra heat sinks: 313,100 maintenance points

Solaris7 still doesn't want to play, at least not with me.

Royal Sovereign looks okay as a battleship candidate.

Overview:

Although many thought that the Naga-class light destroyers were condemned to the reserve mothballs for good, in 2760 Krester Shipbuilding requested a dozen of these ships to serve as testbeds for the incorporation of new technologies in a light destroyer.   While both the Lola III-class and the new Essex-class vessels were already serving in large numbers, ranking SLDF officers assigned to the War Plans Bureau were looking ahead to the next century.   The largest flaw in the Lola III and Essex was their lack of a lithium-fusion battery system, rendering the destroyers incapable of keeping pace with the cutting edge battleships and cruisers of the SLDF Fleet.   Furthermore, experience demonstrated that both current classes of destroyers lacked sufficient anti-fighter defenses and armor protection to survive against modern anti-ship weaponry.

With the SLDF budgets already streched to the breaking point, the planning officers decided against issuing a contract for an entirely new class of destroyer, but instead called for the refurbishment of a dozen demonstration vessels.   To reduce costs still more, the shipbuilding company selected for this contract would be allowed to use (at no charge) existing ships already in the mothball fleets.   Bean-counters and executives for most companies able to design and build these ships saw little opportunity for profit in the production of less than a score of vessels, but the owners and execs of Krester jumped at the opportunity.   Freed from bureaucratic micromanagement from the personnel of the Office of Procurement, the senior design team at Krester saw an opportunity to build the ship they would want to serve aboard.

The design team decided to use existing Naga-class light destroyers as the basis for their new design, christening the new vessel as the Naga II.   At 540,000 tons displacement, the Naga-class vessels were large and robust enough to support the additional engineering and weapon systems, although a survey of the ships chosen did mandate a slight strengthening of the hull structure.   The original pair of low-power drives that gave the Naga-class a reputation for being slow and hard to maneuver were completely replaced with a quartet of high-efficiency transit drives, making these ships able to match the Lola III-class in rate of acceleration.   The Kearny-Fuchida drive cores were overhauled and restored to virtually new condition, and nearly 5,500 tons of lithium-fusion batteries were installed alongside the central shaft of the core.

The dozen NL-35 light Naval Lasers, eight Light Naval PPCs, two White Shark class Capital Missile Launchers, and the single stern-mounted Barracuda class Capital Missile Launcher were retained in the design overhaul, but the original array of eleven NAC-10 light Naval Autocannons were instead replaced by seven NAC-20 medium Naval Autocannons and one NAC-30 heavy Naval Autocannon.   This arrangement saved vital tonnage, and yet retained the same damage profile on all arcs but the stern-quarters and stern.   In these three arcs of fire, the installation of a NAC-20 alleviated one of the few complaints about the Naga:   the lack of substantial firepower covering the stern of the destroyer.   A second Barracuda class Capital Missile Launcher also joined the original mount in the stern as well, further increasing overall firepower.   To meet the War Plan Bureaus call for increased anti-fighter firepower, Krester then incorporated a sizable array of conventional scale high-tech anti-fighter weaponry:   thirty-two large pulse lasers and forty-eight medium pulse lasers arrayed in turrets staggered across the outer surface of the Naga IIs hull.   Frighteningly accurate, the pulse laser turrets gave these new ships a devastating ability to shatter hostile fighter formations.   The design team also increased the number of heat sinks to 1,273 and decided to convert all of the units mounted aboard ship to double-strength models.   Overall firepower was increased by nearly 58% and the new Naga II-class vessels were able to make full and constant use of that heavier throw-weight.

Noting that the WPB called for an increase in the armor protection from that seen in the current generation of destroyers, Krester and its design team went whole-hog.   They removed the original 174 tons of standard armor which the Naga had been contructed with and replaced it instead with 756 tons of ferro-carbide armor plating:   giving this light destroyer greater protection than Congress-class Frigates and Aegis-class or Sovetskii Soyuz-class Cruisers.

The original complement of a dozen aerospace fighters and two combat shuttles were also retained, but Krester expanded the crew quarters for the flight crews to match those occupied by the remainder of the ships crew and gunners.   Space was allocated for a full-strength platoon of 28 Marine Infantry, along with quarters for thirty-nine passengers.   When combined with the required thrity-four officers, one hundred and ninteen crew, and forty-six gunners, the Naga II could accomodate (at full load) up to three hundred personnel.   Fifty escape pods gave the crew and passengers the ability to fully evacuate the vessel during an emergency and storage space for 540 tons of food, water, and life support provided for the needs of three hundred crew and passengers for up to one standard year.   In addition, the original 55-meter diameter grav deck was replaced with a pair of contra-rotating 85-meter units that provided more space for the onboard personnel to maintain their physical and mental conditioning on long-duration voyages across interstellar space.

Finally, Krester expanded the onboard fuel bunkers from a capacity of a mere 2,000 tons of fuel to ones able to handle more than 14,000 tons:   enough to continually thrust at 1-g for an entire standard year before exhausting the fuel supply.   All of these improvements in the basic Naga design carried a hefty price, however, in cargo capacity:   the original's ability to haul more than 140,000 tons of cargo was reduced in the Naga II to slightly more than 54,000 tons.   Still, on a percentage basis of the ship's mass, this represented more of a viable cargo fraction than that carried aboard ships such as the Black Lion-class Battle Cruiser.

The first newly completed Naga II-class vessel (SLS Chimera) was launched in June of 2766, with the remaining eleven entering service at the rate of one a month.   SLS Unicorn was the final Naga II-class ship commissioned into service in May of 2767, just seven months before the Amaris Coup.   Kresters new ships were immediately assigned to the Periphery to undergo evaluation of the design under combat conditions; consequently none were captured when Rim World forces launched their attack on the isolated SLDF forces garrisoning the Hegemony.

Over the next two decades, the dozen Naga IIs served well, displaying an impressive ability to survive damage that would cripple many existing heavy cruisers and live to fight another day.   Crews assigned to the new ships especially liked the concentrated mid-range firepower of the design, although they did express some concern at the lack of ability to engage targets at extreme-range.   However, when operating to screen McKenna-class BattleShips and Luxor-class, Avatar-class, and Aegis-class Cruisers in fast reaction task groups, the lack of extreme-range firepower was not normally a problem.

Five Naga II-class destroyers would survive the fight to liberate the Hegemony and bring Stefan Amaris to justice.   The Liberation of Terra was the first and only known battle in which a Naga II class ship was lost, with seven of the class perishing during that bloodbath.   All five of the surviving ships and their crews joined General Kerensky as he led the SLDF on the Exodus.

"Someone in the Quartermaster Command must have been out of his mind. Why did they order another Warship to do the job of the Luxor Heavy Cruiser? Just look at its specifications, this new Warship carries less armor and less firepower than our Luxor while still leaving unsolved the same problems encountered with all state-of-the-art military products..."

Excerpt from a protest speech issued by Mitchell Vehicles after the decision of the Quartermaster Command to accept a bid from Boeing Interstellar for a new Battle Cruiser Class.
---------------
"I don't think that we have made a mistake in ordering the new Richelieu Class for the SLDF Navy. We need a new kind of heavy blockade-runner, capable of punching holes deep in enemy defense nets or to hunt protected convoys, while still being able to react quickly to changing battlefield conditions, or even to protect friendly troop transports. Personally I don't think we currently have a ship able to fulfill all of these functions in a single package. As to what the representative from Mitchell Vehicles mentioned about the Richelieu being incapable of correcting the perceived problems of the Luxor Heavy Cruiser, I will respond by saying that the SLDF views the Richelieu in an entirely different class altogether. The new Battle Cruiser is faster than the heavy cruiser and capable of firing all of its offensive weapons without heat concerns. Meaning, this ship will hit as hard as the Luxor and the Black Lion in a fight without freezing up like the Cameron.
But let's face it, enemies of the Star League will have Warships which they will use against our convoys or in blockades around our planets. To date we do not enjoy a dedicated defensive weapon to answer that challenge. To alleviate some of the fears of my esteemed colleague from Mitchell Vehicles, this does not mean that the Luxor has no future. To the contrary, these two classes are not competitors, but instead complementary, performing missions that other warships simply can not successfully accomplish. In addition, I would like to remind the Richelieu's detractors how costly our Warships tend to be, and I would like to add that the final cost of this new vessel class will sit between 30% and 50% lower than Mitchell's Luxor Heavy Cruiser. For a ship expected to engage in the thick of battle, this is something the League believes worth mentioning..."

Extract from a statement attributed to Commodore Dorrell made during an inquiry held after protests from Mitchell Vehicles.

Excerpt End......
---------------

These are but two small examples of the debate that raged around the design and production of the first Star League's Richelieu Class Battle Cruiser. While our Order does not enjoy a substantial amount of knowledge on the development of the Richelieu, may Blake forgive us, from the reports recorded during the '64 inquiry (Further proof of the lobbying power of the builder of the Luxor and Essex) and the few surviving battle reports of the Richelieu in combat, we have a vague idea of how these vessels were designed and their mission parameters.

Despite these shortcomings even I must confess that this design only came to our attention only while we were doing some additional background research for our Blessed Order's own Dante Class. Only in Blake's wisdom could a ship as interesting and powerful as the Richelieu slip through the proverbial "cracks" of our Order.

In fact, one of the most glaring holes in the history of this warship is attributed to the unknown origin of the class's name: Richelieu. The current theory holds two possibilities: a French statesman credited with rebuilding the French Navy, la Royale or a class of fast cruisers deployed by the French before the Second World War.
Given the parallels between the original class of blue-water vessels and what we know of the League's Richelieu, then there are several interesting correlations between both the historical and League designs.

I can only pray to Blake that in his wisdom we will uncover more information on this peculiar ship.

From the desk of,

Precentor Guy Valez Mu-VI
Capabilities:

Weighing in at a hefty 940,000 tons, the Richelieu was heavier than both Mitchell Vehicles's Luxor Class Heavy Cruiser or the SLDF's standard Black Lion Class Battle Cruiser, however, the Richelieu is still faster than either warship class with a cruising speed of 2Gs thanks to its massively powerful Carston Pegasus Interplanetary Engines. The mammoth fusion toruses, specially designed for the Richelieu, are extremely capable. Besides enjoying a superb maintenance record, they are capable of propelling the Battle Cruiser to an astounding 4Gs during combat maneuvers. Although unique to the design, this large maneuvering drive was considered necessary for the Richelieu to quickly react to the evasive tactics of enemy vessels while escorting friendly Dropships at full speed, thereby reducing their vulnerability to enemy fire.

Although the propulsion system of the Battle Cruiser was central to the class's design  and function, the ship's designers did not ignore the vessel's capacity to deploy a large offensive armament. The weapon suite of the Richelieu were among the most powerful of the era, using a combination of Naval Lasers, Heavy Naval Gauss Cannons, large caliber Naval Autocannons and Heavy Naval PPCs. Additionally, given the class's mission parameter as a heavy escort/blockcade runner, the weapons deployment unsurprisingly favors a heavy nose and broadside for blistering dive assaults. ( During the Mitchell Vehicles Inquiry of '64, one of the central themes of their protest against the Star League for the reduction in Luxor production was the distribution of the Richelieu's armament. The company believed that the vessel lacked the overall strength of the Luxor and that the reduction of firepower in some of the Battle Cruiser's arcs would prove to be dangerous to the vessel in combat. - G.V)

Despite the presence of a large number high-heat energy weapons, an impressive number of heat sinks allowed the Richelieu Class to fire of all its weapons in combat. Both the presence of the heavy nose and broadside armament, and the effective heat-dissipation system clearly displayed how the ship's engineers intended the vessel to operate in a strike capacity, using its mobility and firepower to decimate the enemy.

This strike profile was also a necessity for the Battle Cruiser since the vessel's armor sleeve was not thick enough to sustain the ship in a prolonged slugfest. Unfortunately Boeing Interstellar, the Richelieu's producer, was forced to reduce the ship's protection in order to afford the warship its impressive speed and armament. Still, the designers considered the armor tradeoff acceptable since the Richelieu's mission profile necessitated a quick Alpha Strike capability. Also, to help complement the vessel's short-range protection from small craft and enemy Aerospace assets, two squadrons of Aerofighters are available, ensuring that most small threats will be dealt with quickly.

Finally, as the warship neared its completed design the Boeing engineers decided on working something special into the new warship that would truly set the class apart from all other SLDF warships. Taking a page from the ancient shipwrights of Terra, who often built ships that were as much a work of art as they were functional tools, master crafted a special nose for the warship in replica of the Jolly Rogers of old. (Again, protested by Mitchell Vehicles as a waste. The League's Quartermaster Command was quick to point out that the Richelieu was still millions of Star League Dollars less than the Luxor. - G.V.) This was chosen after Boeing consulted a number of psychological professionals and naval historians to help create a vistage that would strike fear into the heart of the enemy.

From the reports we could decipher, it succeeded beyond any expectation.
Battle History:

In December 2766 Stefan Amaris plunged the Star League into Civil War when he staged his illegal Coup to take over the Terran Hegemony. The bloody sneak attack devastated the unaware citizens of the Hegemony and her industries. Boeing Interstellar's Terran assets were no exception and as Republican troops bombed the orbital yards housing the two ships both Richelieu captains scrambled to extricate their stricken vessels and any personnel able to get aboard in time. Despite the best efforts of the Rim Worlders, and thanks to the sacrifice of Boeing's security force, the two unfinished Battle Cruisers managed to blast their way free of their moorings at a significant cost. Fighting a running battle all the way to the nearest jump point, the two SLDF warships barely escaped intact.

After escaping the clutches of Amaris's forces, the two warships slowly made their way out of the beleaguered Hegemony. Traveling through uninhabited star systems, the two Battle Cruisers eventually linked up with League forces in the Free Worlds League. Once in the hands of the SLDF, both ships were eventually repaired.

Over a period of eighteen months, the SLDF completed the two armaments of the two warships, changing their original profiles with whatever materials were available. Following the conversion the two Battle Cruisers were assigned to SLDF resupply operations, protecting the Dropships trying to deliver supplies to besieged forces behind Republican lines.

Fortunately for the Richelieu and the Jean-Bart, this was the mission for which they were designed to fulfill. Even with the jury-rigged and patched weapon suite, which often required constant maintenance, the warships were nevertheless devastating. (It should be noted that in the early stages of the Civil War, the SLDF assigned units to these desperate supply missions as a necessity, with the rule of thumb being improvisation in the interests of survival. - G.V.)

An important number of holovids show footage of the two vessels in operations during the later years of the Coup, with an impressive level of coordination during operations, even for sophisticated SLDF warships. (From what we could ascertain the captains were not related but did attend military school in the same class. - G.V.) A more intensive research into the surviving Battle ROMs could provide us with precious information on the subject.

Throughout the intervening years of the Coup before the Liberation of the Hegemony, the two Richelieus operated on the outskirts of Terran space, testing the Republican defenses. Often the last sight a Rim World's Dropship Captain saw, the Battle Cruisers would play a crucial role in the liberation of the Terran Hegemony by providing the SLDF High Command with vital recon information on the conquered worlds.

The final tale of this proud class ends with the last major naval battle of the civil war: the Liberation of Terra. After extensive research and analysis of battle casualties, and survivor after action battle reports, we found that the two Battle Cruisers were among the volunteer flotilla that jumped in the second wave with the sole mission of destroying as many Caspars of the Republican Space Defense System as possible before the arrival of the invasion force.

Although exact information surrounding the specifics of the resulting suicide mission do not exist, thanks in part to the total destruction of all forty warships and their brave crews, we know that the Richelieus, along with their fellow SLDF brethren, accounted for more than 150 drone warship kills.
Variants:

Even though the Richelieu Class Battle Cruiser almost ended in its infancy, the class enjoyed a number of refits, conversions and variations during its brief history. Of the two Battle Cruisers, it was the Jean-Bart that suffered most of the changes necessitated by the Amaris Coup. Leaving Boeing's shipyard only partially complete, Star League engineers were able to add a wide variety of weapons and equipment to the Bart, some in haphazard fashion. From the surviving Coup-era League engineering records it would seem that the Jean-Bart was outfitted predominately with Naval Lasers, and a host of AR10 Launchers. Notably absent from the vessel were the Heavy Naval Gauss Rifles located in the ship's nose, though the ship-to-ship missile batteries would have been wildly successful in interdicting enemy Dropships and fighters. We also have reason to believe that the Jean-Bart had a portable HPG installed as its superstructure was finally completed. However, given the difficulty and length involved in installing such a sophisticated piece of equipment, its value to the warship is highly dubious.
Deployment

According to our extensive research of the surviving SLDF production records on Terra, we have ascertained that only two Richelieu Class Battle Cruisers were ever produced: the Richelieu, namesake of the class, and the Jean-Bart.

Due to the time delay imposed by the '64 Inquiry, production of the warship was delayed until 2765. When the Amaris Coup devastated the Terran Hegemony at the end of 2766, Boeing Interstellar had only the Richelieu nearly operational, undergoing its final shakedown tests before being assigned to active operations. The Jean-Bart, however, was but 75% completed, without its weapon suite installed, large portions of its armor package and only a skeleton construction crew to service her.

Although the devastation of the Civil War would prove to be the death knell of any future members of the Richelieu Class, along with so many other glories of the Terran Hegemony, research has led us to believe that a copy of the Battle Cruiser's technical schematics were transmitted to Boeing Interstellar's Galax Headquarters during the occupation, however, we currently have no way of confirming this theory. (Attached is a copy of a proposed Shroud Mission for ROM's consideration. Perhaps a Schatten can be deployed. - G.V.) To date we have been unable to obtain tangible proof as to whether or not the Richelieu's engineering plans have survived the Succession Wars in Boeing's hands, or if they were lost with the technological decline. We do know for certain that no copies of the Battle Cruiser were taken with Kerensky and the SLDF into Exodus. If the Boeing copy remains viable it is likely the only one in existence.   

There are also persistent rumors pointing to the hulk of a surviving Richelieu, perhaps the Jean-Bart, placed in deep orbit outside of Pluto along with a number of wrecks left over from the invasion. As a member of our Blessed Order, I can lend no credence to these baseless rumors. Our research has confirmed that there is no such derelict orbiting anywhere near Pluto. In all actuality the rumor probably developed in the early 2800s after Terran prospectors located the remains of a destroyed Texas near the system's Kuiper Belt.

smart money would be on designing the destroyer and frigate in tandem, using the same frame.  the Frigate would be significantly faster and haul more droppers but carry lighter armament.  the destroyer would be slower (maybe even as slow as a 3/5) but pile on the guns and armor like mad.  overall thier tonnage would be identical.

because they use the same frame (read identical SI), the cost of producing both vessels would be mitigated.  if I had to choose a pathfinder vessel to adapt for this idea, it would probably be the Concordat Frigate. boost the tonnage to half a million and work from there.

Always have 100+ SI on nuke magnets, that way they can survive a penetrating hit from a fighter missile.

No, just the consequence of the standard nuke rules in the 3070 Jihad HS.

A fighter carried Alamo does 10-cap and crits at 10+ to deliver 10 times it's original damage directly to the SI of the target for 100 damage. It is survivable if you have over 100 SI but if not then it is a headshot inta-kill. Having seen one too many battleships go down to the annoying "fighter that got through" I always have over 100 SI on serious house designed combatants.
