A few things about this design and some background. Every time I looked at this ship, I thought it was a lousy design. However, the Real World is full of lousy designs that have been mass produced and thus become the standard for whatever reason. So that is what I had in mind when I came up with this.

This design originated around 750 by the Zhodani Naval Architect Division when they thought that there was going to be lack of patrol ships following the launch of the 7th Core Expedition which commandeered a lot of Zhodani resources. The idea was to create a quick-and-dirty design that would convert already existing commercial vessels to pocket carriers. The best candidate for this was an older Jump-4 cargo carrier used in the outer provinces of the Consulate known as the Blerts class. So the program was created and designs were finalized. It was envisioned that the ship would be a fighter carrier only and not itself engage in combat except outside of effective range of enemy weapons (mainly because it was too fragile to engage in close combat). Almost as soon as the program was created, it was cancelled in favor of more "politically expedient" designs.

The inexpensive and easy to mass produce Iezdia fighter was chosen to provide the primary offensive punch of the Shivva class. The 9G drive allowing for fast hit-and-run attacks more than making up for its inability to take multiple hits.

The Shivva class only saw use as a handful of prototypes until the Imperial Psionics Suppressions of 800-822 when the need for a high jump escort for civilian ships full of psionic refugees fleeing the Imperium became imperative. Thus the Shivva plan was dusted off and placed into motion. Hundreds of old Blerts transports were voluntarily nationalized by the Zhodani Consulate Navy (many with their crews demanding to stay on). Thus when Zhodani historians talk of the bigoted violent discrimination against psions by the Third Imperium during the Psionics Suppressions, they include the tales of bravery and heroic self-sacrifice by Shivva crews to ensure that as psions were rescued from the Third Imperium as possible. Over 400 Blerts were converted to Shivva's during this time.

After this, the Zhodani Navy made some modifications to the ship design and then continued to build the Shivvas, this time from the ground up. Some of the class have been in operation for over 250 years, although ships this old are often just used as training vessels. There are no common spaces on the Shivva class and the crew often is under stress because of this.

The Shivva has a crew of 28 (Captain/Astrogator, 3 Pilots, 3 Engineers, 12 Gunners, 12 Small Craft Crew) of which the Captain/Astrogator is a Noble, the Department Heads are Intendants, and the rest of the crew are usually Proles). During normal flight operations, the Gunners help the Engineers and Small Craft Crew with maintenance and readiness. During combat operations while half of the Gunners man their turrets, the rest handle reloading munitions and damage control.

The Shivva class has its own subculture associated with it. The Captain usually gets a Shivva as his first command and is encouraged to be a fatherly figure to the crew both due to tradition and partially due to the lack of having a member of the Tavrchedl' on board. Department Heads are encouraged to act as older siblings to the crew, not just ordering them around but also guiding them in their lives and careers. This is thought to help mitigate the stress of a typical deployment.

A typical deployment for a Shivva crew is 6 months although life support supplies can last for 7 months without resupply. The 0.25dT cargo space on the fuel shuttle and the 0.05dT cargo space on the fighters are often combined to create 0.75dT total which will then carry life support related foodstuffs and light celebratory intoxicants for the Dliebrzdinsh - a small party held onboard to celebrate the midway point of the deployment.

Let me know what you think.

Check tonnage, I think you are a bit over...

Jump Drive should be 65 Dt, the percentage + 5 Dt (HG'22, p16).

PP Fuel should be 3 Dt for four weeks, it's rounded up (HG'22, p18)

A triple Beam Laser turret consumes 13 Power, 1 for the turret and 4 each for the lasers.

Missile/Sand turrets already hold some ammo, you might not need so much magazine.

I don't see how you get 137.5 Dt docking spaces, it's 110% (round up) per craft, so about 9 Dt each for the fighters and 55 Dt for the shuttle = 10 * 9 + 55 = 145 Dt?

Crew space is very tight. You can get away with double occupancy, but quad is probably a bit too much. Also see the "Common decency" box, (HG'22, p24).


OPINION:

A Dispersed hull in CT carried all the craft on the outside, not in internal docking spaces, while still counting the tonnage in the "hull". Basically the Shivva was a ~500 Dt ship that carried ~100 Dt craft.
In MgT I would do a ~500 Dt hull with "600 Dt" drives and carry the craft externally in docking clamps, see the "400 Dt" Lab ship, (HG'22, p185).


The Shivva is a long range patrol (spy?) ship, relying on fighters for combat. I would include better sensor equipment and more comfortable crew quarters.


The original had a m/6fib, quite a decent and expensive computer, I might include a better computer.


You might need a few missiles (cargo) and fuel to resupply the fighters? Perhaps even UNREP to do it quickly?

A 9 G drive is TL-15, max at TL-13 is 7 G, see the TL under the drive percentage on p16.

A single missile launched for 7.5 Dt + pilot is not very exiting but what can you do? I might downgrade the sensor and make the craft smaller, relying on the mothership for sensor information. The better sensors works for the patrol/spy role.

Each fighter supported by a swarm of very light drones (Virtual Crew)? Each "fighter" in CT then becomes a fighter and a couple of drones, both versions launching 3 missiles per round?

I would prune it down to basics, replacing all payload with a large cargo space with some Collapsible tanks and some foldable Acceleration Benches, that way you can carry cargo, fuel, and/or people as needed. The shuttle can then act as life boat if necessary.

I might use a 3 Dt bridge instead of the cockpit, to get the airliner look, rather than the F-15E look.

You only need 1 Dt fuel.

Now, I deliberately did not use High Guard to make the design and used the Core Rulebook 2022 Update instead because I thought that it would help to bring about that retrofitted transport feeling that I wanted to achieve. I wanted the ship to have the feeling of a WW2 submarine for the crew, which is why it is so cramped and uncomfortable. Same with the fighters and multirole shuttle.

I never really saw it as a spy ship or surveillance craft because the design is absolutely wrong for that (a spy ship, with the fighter compliment of an escort carrier?). As a patrol ship, it is also poorly suited. As a picket ship or an escort, it is well suited especially with the fighters flying a CAP and extending the detection ranges by doing so.
