Overview

Based largely on the Terran Hegemony's County class transport, the Kurita 
built Ropucha was intended to do the same job as its progenitor, except 
better and cheaper.

The Ropucha had a number of similarities to the County. The ship was of 
identical mass and had an identical armor profile. It also had the poor 
thrust capability typical of the County and most other transports. The 
weapons battery was also similar to the County if slightly smaller, a total 
of eighty naval lasers, and had a similar intended role, that of ground 
support fire.

It is on transport capabilities that the Ropucha radically differs from the 
County. Whereas the County could transport a combined arms brigade totaling 
five ground regiments with aerospace support, the Ropucha could transport a 
staggering thirteen regiments. What's more, the Ropucha did it without using 
dropships. One hundred and thirty specially built dropshuttles, each capable 
of transporting a single mech or heavy tank, three light tanks, or four 
hundred and fifty infantrymen were used to deploy the ship's complement. 
Though it would take on average forty five minutes to launch all of these 
dropshuttles, even longer to load them all with troops in the first place, 
and at least five trips to deploy the entire troop complement, this had a 
number of advantages. In the first case, because the standard dropship 
docking collar tended to seriously drive up the cost of a warship, this 
method allowed for a transport capable to carrying large numbers of troops at 
a fairly low cost.

Secondly the massive number of small transports allowed a Ropucha to respond 
to numerous threats across a planet more easily than a standard transport 
with a limited number of dropships.

The main disadvantage, however, was the vunerability of the Ropucha and its 
dropshuttles during the long loading and unloading process. In order to carry 
the troops they were capable of carrying, the dropshuttles had to be unarmed, 
though they were fairly well protected, and the Ropucha could not always 
protect the small craft. To deal with this problem, cubicles for over a 
hundred aerofighters were included. To increase the versatility of these 
fighter bays, they were made large enough to accomodate dropshuttles if need 
be, allowing the ships to carry as many as two hundred and thirty eight of 
the transports if the need arose.

Despite its incredible troop carrying capabilities, the Ropucha had a number 
of flaws. In the first case it was, by neccessity, huge. Though only eight 
hundred thousand tons, with twenty one decks devoted soely to troops and 
cargo, the ship was over 1.2 kilometers long. When these ships were damaged 
or needed maintenance only the largest shipyards could accomodate them.

The Ropucha's biggest problem, however, was the main vehicle bay. The need to 
be able to load mechs and tanks into the ship's dropshuttles easily led the 
engineers to design each of the eight vehicle decks as largely open spaces 
with a minimum of compartmentalization to facilitate moving mechs and 
vehicles. Though small craft bays surround each of these decks and provide 
some protection, any breach of these decks would vent the ENTIRE deck into 
space rather than just a single compartment. Airlocks on each deck, 
originally intended to allow for mechs to be dropped on a planet directly 
from the transport, only exacerbate matters, creating weak points in the 
ship's hull. Even worse, massive lifts on each deck that allowed vehicles to 
be moved between the bays also created the possibility that multiple decks 
will suffer the same fate when one goes. The only sections of these decks 
safe from this is the central core, built around the KF-drive. This provided 
limited access to the rest of the ship, however the passages through the core 
were not large enough to accomodate more than people and the smallest of 
cargo.

The eight cargo decks suffered similar problems, having been designed much 
the same way as the vehicle decks. The five infantry decks, on the other 
hand, were much better compartmentalized and protected from hull breaches. Of 
course they were also hideously crowded, with over six thousand troopers 
crammed into a relatively small space. To make up for this to an extent, the 
ships carried an extensive recreation facility on six massive grav decks.

Another flaw existed simply in the ship's enormous transport capability. 
Quite simply it could be too dangerous at times to risk a Ropucha in combat. 
The destruction of a fully loaded Ropucha would also mean the loss of 
thirteen regiments of ground troops and over two hundred small craft and 
aerofighters. In other words the Ropucha was the ultimate example of putting 
all ones egg's in one basket. Though the Combine constructed two Ropuchas 
just before the dawn of the twenty-eight century, for these reasons they soon 
abandoned the idea.

Both Ropuchas were put into reserve status after only forty years of service. 
Their poor performance during the Davion war of succession, including one 
nearly disastrous moment when the Ivan Rogov, carrying nine regiments to 
reinforce Kurita forces in the region, was nearly lost at Royal to Davion 
aerofighters, had convinced the high command that the ships were a bad idea. 
They were not reactivated until the start of the first succession war, and 
even then during most of the war they fulfillied transport duties in rear 
areas. As the fleets of each state dwindled, however, the need for warships 
soon outweighed the risk, and both Ropuchas were sent into the fray. The 
Ropucha was destroyed soon after, while the Ivan Rogov nearly lasted to the 
end of the first succesion war. The ship was reported lost to a Steiner task 
force while transporting six regiments of replacement troops to the steiner 
front.
