[Shipyard] Lurushaar Kilaalum-class Corvette

[robject]

Corvette EB-EA53 Lurushaar Kilaalum MCr315.7 [Clan Severn]

Disposition: In Service

Built on a 500-ton TL-13 winged airframe, the Corvette is the Navy’s equivalent of the Scout/Courier, only bigger, faster, and better armed. It is fitted with the Ansar b3-G jump drive, the Yard 7 mL/5 maneuver drive, and the Grid 5p Tokamak/L3 power plant, giving performance of Jump-3 and 5G acceleration. Fuel tankage supports one jump and three months of operations. It has fuel scoops for gas giant skimming. Adjacent to the bridge is a Model/3 computer and an extensive sensor suite. There are five hardpoints filled with an array of powerful weapons.

Actual volume: 498.5 tons
Crew comfort: +1
Passenger demand: -5

20 ships? That sounds like a very low production run for the Imperial Navy. And a very low production run for the IN counterpart to the Scout/Courier. The IN would need thousands of scouting vessels. One squadron of 8 corvettes per regular fleet would come to 2400. Not necessarily all of the same class, but the IN would be ordering its small escorts by the hundreds.

Unless there were some reason to discontinue the planned production run prematurely.


Hans

 

[robject]

I covered my bases by calling it the production run for the "Series 1100" class, whatever that means.

There's also a question as to whether or not Marc intended to increase it to 500 tons; I seem to recall that it is not an accident.

Hans

Agreed, also isn't J3 inadequate, it needs min J4 to keep up with the Fleet, or else larger warships end up being diverted to Courier duty.

320 Fleets, possibly 3,200 squadrons, production run needs to be in the 10,000+ range, there is a 400t Courier in CT FS with J6, M2, indicating the IN uses different ships for Scouting and Courier duties.

Agreed, also isn't J3 inadequate, it needs min J4 to keep up with the Fleet, or else larger warships end up being diverted to Courier duty.

The question that answers many other questions is probably: in what sense is it like a Scout/Courier?

 

[Dagrill]

Sorry I don't want to appear too negative as I really appreciate what you are doing converting all these ships to T5.

I could certainly use this design as an upgrade to the Type T patrol corvette and I think that's what you where going for originally.

Apologies for any misunderstanding

Kind Regards

David

 

[rancke]

The question that answers many other questions is probably: in what sense is it like a Scout/Courier?

My guess would be that it's the ship the Navy uses for the same purposes that the Scouts use the Scout/Courier: Scouting and short-distence courier work.

But why do I have to guess when I can just ask the author in what sense he meant it when he wrote that it was the Navy's equivalent of the Scout/Cruiser?

So in what sense did you mean it when you wrote that it was the Navy's equivalent of the Scout/Courier?


Hans

 

[robject]

But why do I have to guess when I can just ask the author in what sense he meant it when he wrote that it was the Navy's equivalent of the Scout/Cruiser?

That made me pause! But really that would be Marc, not me: it's quoted from T5.

 

[rancke]

That made me pause! But really that would be Marc, not me: it's quoted from T5.

Oops. My mistake. Revert to my guess, then.


Hans

 

[Kerdied]

Please, what is the minimum crew required to man this ship?

 

[robject]

Please, what is the minimum crew required to man this ship?

A commander, up to twelve crewmen in double occupancy as needed (but at least: pilot, astrogator, sensop, medic, and three engineers), and five gunners, in a barracks. A second barracks has room for up to 5 marines.

 

[rancke]

Agreed, also isn't J3 inadequate, it needs min J4 to keep up with the Fleet, or else larger warships end up being diverted to Courier duty.

Perhaps it is designed to be carried by larger ships until deployed. Or to be attached to fleets with J3 combat vessels, in which case there will be another version with J4 capability.

320 Fleets, possibly 3,200 squadrons, production run needs to be in the 10,000+ range, there is a 400t Courier in CT FS with J6, M2, indicating the IN uses different ships for Scouting and Courier duties.

Perhaps not 10,000+, but certainly in the high hundreds or low thousands. That's assuming that the IN has more than one ship class for each of its functions.


Hans

 

[aramis]

The canonical fleet courier is not the Type S. The Type S carries mail off the X-boat routes to everywhere else. (Sup 9, p. 11)
The Fleet courier is a 400Td J6 2G courier with a 5 man crew. (S9, p 20)

Yes, we know. The flavor text for this ship says its the "Navy’s equivalent of the Scout/Courier". That is to say, the vessel employed by the Scout Service for short hops. Presumably the Navy uses this model for short hops. One might infer that the Navy doesn't use J2 vessels for scout and courier work.

In any case, the Fleet Courier is not the Navy's equivalent of the Scout/Courier, but the Navy's equivalent of whatever the Scouts use for J6.

The scouts don't need a J6 for what they do.

 

[rancke]

The scouts don't need a J6 for what they do.

Even if that is true it doesn't mean that the Scouts don't have some. They may, for instance, feel a need to deliver reports faster than they can do without J6.


Hans

 

[robject]

[The Corvette is] the "Navy’s equivalent of the Scout/Courier".

[...]

[Therefore] the Fleet Courier is not the Navy's equivalent of the Scout/Courier, but the Navy's equivalent of whatever the Scouts use for J6.

Hans

In other words, just as the Scouts have a Corvette-equivalent, they might also have a Fleet Courier-equivalent.

It's possible. Perhaps even probable, due to an aberration in the Spinward Marches xboat route. Do you know what aberration I'm talking about?

 

[robject]

(NOTE: I think the aberration has been retconned away, since it appears to be absent in travellermap.com).

 

[rancke]

It's possible. Perhaps even probable, due to an aberration in the Spinward Marches xboat route. Do you know what aberration I'm talking about?

The jump-5 X-boat link from Tenalphi to Strouden, you mean? Yes, I see that it's been replaced by a link from Tenalphi to Persephone.

I hope we can take this link as evidence for X-boat links occasionally bypassing intervening systems that appear to be on the routes. Such as interdicted Penkwar (and presumably also Spirelle).


Hans

 

[aramis]

Even if that is true it doesn't mean that the Scouts don't have some. They may, for instance, feel a need to deliver reports faster than they can do without J6.


Hans

At which point, they probably make use of the standing navy J6 runs... Or use the same plans the Navy does for the Fleet Courier.

For the most part, they're going to make do with J1-J2 to/from the X-boat net, and J3-J4 along it.
