Mammoth Class Runabout

Mission Statement

Near the end of the Dominion War, Starfleet's Corps of Engineers proposed a new runabout design, to cope with the losses of the Danube.

The design, filed as "DNB-successor MMM-TH-1 / NXR-01", got rejected. Not knowing exactly why it was rejected (the design was practical in their eyes, at least more than the Danube), the normal procedure of rejected designs is to destroy them. However, someone filed it, and after the Reman incident of 2379, some engineers at Utopia Planitia uncovered the file containing the "DNB-successor MMM-TH-1" design. They reviewed the design, and concluded that it was too small. After a small discussion with the Corps of Engineers, they decided to give the design (or more precisely, the specifications) another chance. The design got an overhaul, which, among others, sported a change of the nacelle type to the Defiance line of integrated nacelles, and an increasement of internal volume. The two torpedo launchers were left in a separate package on top of the vessel, but were placed in two separate hulls, creating a catamaran design which doubled as shielding for the warpcore. Next point on the agenda was the modular question. Starfleet Command insisted that the design be modular, and as such the pod stayed, although in a different configuration that would allow it to be dropped when necessary, enabling the design to be accepted into Starfleet's Marine Corps as well. Design lineage from the new Scout vessel and the widespread-in-use Type 11 furthermore improved the design. It is a welcome addition to the armada of small (if you can call it that way) craft Starfleet is operating.

Medium level Structural Integrity Field

Warp Speeds
Normal Cruise:      7
Maximum Cruise:      8.2 (last testresult stardate 66702.76)
Maximum Rated:      not yet tested, presumably 8.7

Expected Hull Life
65 years

Refit Cycle
Minor:         0 year
Standard:   10 years
Major:         20 years

Notes
The highly modular nature of the new pods, combined with the locking mechanism used on the Mammoth series, means that the craft can harbor stacked pods. With this technique multiple pods can be stacked above another. Although the test with two pods (TF MMM-TH-70 / SD 66621.6) was successful it is not yet know how the deflector system will react to more stacked pods.

The Mammoth series is equipped for mission durations of at least 30 days, with the matter- and antimatter fuelcell providing fuel for at least 35 days at Warp 6; also, a large portion of the nose can be used to store replicator matter. Although the Mammoth series will probably never leave a base without a pod, the ship can be flown without one without compromising the needs of the crew.

 Very nice design configuration BorgMan! I like the catamaran style of look it has.
 What bothers me is the "second" stacked pod idea. Would the warp field on this size of vessel be able to extend far enough to encompass the second pod? I would think the field would be to weak at a level of the second pod height, putting extreme warp drag on this pod.

I must admit I really like this design, as well as the level of detail that was put into this, however what I am concerned about is the crampped conditions that the Crew would be put in for missions that normally require a runabout type of mission. as we know they are normally longer duration and farther distance then normal short range shuttle craft.

This runabout has a sonic shower with folding toilet, two bunks, a big replicator and a two-person transporter. I saw screenshots of the aft compartment from the Danube, but when you compare it to the outside you come to the conclusion that it isn't possible. That aft compartment indeed is very big, but I thin I've folded the whole thing into a compact design that should work.

I don't know how long a Danube ought to be operational, though... According to DitL speculation:
Quote
The first requirement for the Runabout, issued in 2342, called for a vessel based on the Type 9A cargo shuttle but capable of short and medium range interstellar operations carrying out limited spatial and planetary surveys. The fuselage was lengthened from 10.5 to 14.8 metres, allowing a much larger antimatter fuel cell to be installed to increase the vessels endurance from 36 hours to fifteen days at Warp 2.2.
Again, these specs are speculated to be for the direct predecessor of the Danube; I now realise I have based my specs on these numbers. Anyone able to update me on that matter?

A second pod under the first one would not be a problem: in fact, it would mean that the warp field would have to extend as much down as it is always going up, so I think I have that part covered.

Attached is a wide-angle shot of the aft compartment with the door to the sonic shower opened. I haven't experimented with the lights just yet so it possible that I will be adding extra's in the ceiling or so...

I can see your point now BorgMan, but in your OP, when you said

...multiple pods can be stacked above another.

I just assumed that the pods were stacking on top of this runabout. If they are in fact carried under slung, I can see now how a warp field would easily encompass a second pod configuration. ^_^

Wow...this design is really sweet!  I have the same concerns as Nova, but what you said about the Danube is very true.  Nice work!

*grumbles* I had some trouble with my internet so I wasn't able to let you guys drool over the next set of pictures. For those who ask... Yes, that's a Mammoth being build, and in the background are two of the pods it can carry. Enjoy :)

Yes this is truly an awesome design
