Devlin Stone's coalition faced many nasty surprises from the Word of Blake as
they liberated the worlds of the former Blake Protectorate and Terra. Most of
these surprises were the result of technologial achievements. However, the
Akula class missile submarines were not particularly advanced but were quite
unconventional. Submarines of this size had become quite rare after mankind
took to the stars. In recent decades, the Draconis Combine had re-introduced
such craft for protecting water-rich worlds, including the similar Triton class
missile submarine. While the Triton was quite formidable in defending coastal
areas, the Robes' Akula class submarines provided unprecedented flexibility.

The Akulas were a danger to virtually every coalition force on the water worlds
they were defending. Equipped with twelve of the sub-capital Pirahna missile
launchers, the Akulas are capable of engaging all manner of targets. Ground
units could be bombarded, atmospheric targets could be directly engaged and
inbound dropships could even be targeted in low orbit. Also, in a few cases,
surface naval vessels were, quite literally, blown out of the water. The key to
this flexibility was the Akula's extensive communications suite. This allowed
it to recieve targeting data from any friendly units and satellite uplink.
Further, it could deploy its own network of remote sensor bouys. So, even when
completely isolated, hunting an Akula was a dangerous task.

Because the Pirahna missiles could launch from deep underwater, addressing the
threat of an Akula meant either directly engaging it with other submersibles
(which were rarely availible) or waiting until the Akula was forced to surface.
The latter option was also difficult and tedious. With a fusion engine, a small
crew, adequate kitchen facilities and a med bay, an Akula could remain
submerged for months. Also, an ECM suite and a top speed of over 50 knots made
an Akula's movements difficult to track and anticipate. Further, a compliment
of 360 Pirahna missiles meant an Akula could remain a strategic threat for
quite some time before needing to re-arm. Finally, if forced to engage other
naval craft, an Akula had two torpedo turrets, each with 60 tubes. These could
fend of other craft for a while, but this was a last resort.

So a swimming dropship that can swat fighters and ships and remain independent for long periods... smokes m8, this thing would be a pain to go after, but you couldn't ignore it either.  The cargo space means you can load up on supplies or bring supplies in to any coastal area, so you can support threatened areas or be a long-time pain in the posterior to a force that may already have captured the rest of the planet.  Add in being piloted by zealots, you have a nasty platform here.

So a swimming dropship

I was wondering why so heavy and so quick.

The mass is really determined by the way internal space is calculated for large support vehicles. The formula is 35 + Tonnage/100. So, even just to have enough space for the 12 Pirahna launchers, it needs to be 18,000 tons. Add in the other weapons, accessories, crew quarters, etc. and at 22,000 tons this thing is using 254 of its 255 spaces. I could have made it 21,900 tons, but that just seemed awkward.

With space at a premium, I found I had a bunch of extra tonnage left. So, I gave it a reasonably big engine, which actually gives a top speed similar to the real Akula-class subs that I patterned it after.

Thanks for the reviews though! Nice to know somebody saw this.
