Indefatigable-class Battleship (AU with thanks)

[Dragon Cat]

Here's a relatively new ship class from my AU ( I know I've got older designs to post but this one has sat waiting to join the AU for ages).  Originally JA Baker sent me the basic design based on his newest design (new in September 2014) I've played around with it a few times since then changing it as I came up with new tech and as new tech entered BattleTech.

So here it is feel free to comment (I changed it by hand but I think I have it all right math wise)

Overview
The original Indefatigable-class was a far different beast from what is
currently being built to serve in the Federated Suns, Lyran Commonwealth and
Star League Defence Force navies.  Originally designed to escort the Columbia
and Mercury classes into battle it was a class that was surplus to the needs
of the AFFS navy and a class that would never be built.  Enter the LCAF and
SLDF who both required a class as a filler before homegrown designs were
ready to be produced and were willing to pay the price which allowed the
builders to produce two vessels for the Federated Suns on top of those built
for the other states.

Capabilities
Originally designed as an escort for the current Battleships serving the AFFS
the vessel needed many changes to serve in the LCAF and SLDF Navies.  The
first change to the Indefatigable was to lower its maximum speed from 4G to 3G,
this made room for the change and expansion of the naval firepower of the
Battleship.

From the original design the AR-10 Missile Launchers have been retained and
expanded on allowing for the use of capital missiles from almost any angle
of the Battleship.  Similarly the Naval Particle cannons have been retained
giving the WarShip heavy hitting long range firepower.  Similarly the Naval
lasers of the original design were retained and redistributed into eighteen
twin turrets spread around the hull.

This is where the similarities of the designs end however while the original
design featured Medium Naval Gauss Rifles the Lyrans called for a heavier
variant, initially attempts were made to replicate the Clan's Reapers but
this experiment reportedly failed badly, with the design settled on the
heavie standard variant several more were added to the final design further
expanding the designs heavy hitting firepower.

Conventionally the mix of large and medium standard lasers supported by medium
pulse lasers, with forty-eight individual weapons, was replaced wholey with an
array of thirty-six Extended-Range Large Lasers increasing the range and
overall firepower of the array.  Backing these weapons up are thirty-two
Silver Bullet Gauss Rifles and twenty-one Extended-Range Long Range Missiles
spread around the hull giving extensive anti-fighter, Small Craft and DropShip
firepower from all angles.

Four DropShips (often C3 equipped Pocket WarShips), sixty aerospace fighters,
ten small craft and eighty-four Battle Armour equipped Marines give the vessel
more options while four hundred passenger quarters give the bay personnel and
any passengers on board the vessel a comfortable journey on extended patrols.
More than seventy-six thousand tons of cargo space keep the Indefatigable's
supplied with parts, additional fuel, water and food.

Finally at the insistance of the Star League Defence Force designers added
an Advanced Lithium Fusion Battery Mk II allowing the vessels of this class
to make additional jumps over conventionally equipped LF Battery vessels. 
A Naval C3 allows the ships to coordinate their fire with similarly equipped
DropShips and WarShips while an advanced Naval Anti-Missile System, provided
by the SLDF, gives the vessels of this class a centralized Anti-Missile
control.

Deployment
In an agreement made between the Federated Suns, Lyran Commonwealth and
Star League Defence Force the Federated Suns initially agreed to produce six
vessels of this class with two each joining each navies.  These vessels were
all delivered in 3107.

A very meaty lady and it just shows the industrial muscle of the Suns that they could produce 6 of these ships and deliver them all at the same time.

[Wrangler]

So you got Battleship's escorting Battlships??  :o

Nice beefy ladies, like Marauder said.  Did you guy design these ladies by hand?  I have wicked old HMA that never works when i try design a ship (stupid need life support or add gunner crap error).   I had always wanted to submit a ship to some spawning universe, but never got around to do one.

I like the Indefatigables, their though girls, that have alot of throwing power at range.

Marauder nothing else in the Suns was built that year they through everything into these ships it likely won't happen again unless something like a Succession War breaks out the economy only managed it because of cash flow from the Lyrans and SLDF

Wrangler that's why initially they were turned down for production the AFFS didn't need Battleships the Lyran and SLDF cash got them built.  I think JA Baker built them in HMA I modded the design by hand it took a while...

[JA Baker]

Attached is the HM:Aero file for my original design, and here is the book cover that inspired it:
