In the same vein as the Explorator-class jumpship, this is an Invader "upgraded" to a 1/2 25 ly primitive jumpship.

It's got the same three hardpoints, but dropping to a 25 ly primitive jump core frees up thousands of tons, even if you factor in the amount eaten up by the new more powerful engine and the structural integrity. The fuel bunkerage is larger as well, 2500 tons, or 126 days of travel at 1G. It's got the legs to go really far out into the boonies if it wants to.

I also took the liberty of adding 4 more small craft bays for those private citizens who aren't wealthy enough to have their own dropship, but are still wealthy enough to have a personal spacecraft. This is in addition to the 2 smallcraft that a normal Invader would be carrying and using to resupply. Resupply is less of an issue since the ship doesn't need to putter around anymore. The transit drive is proper strong enough that if it needs to fill up on supplies, it can damn well go and get some.

I also added 6 fighter bays for defense.

The biggest difference is 8600 tons of cargo, which means it can straight carry more stuff and go more places without fear.

I would buy it...
"For the Angel of Death spread his wings on the blast, And breathed in the face of the foe as he passed:And the eyes of the sleepers waxed deadly and chill, And their hearts but once heaved, and for ever grew still!"

How much cargo would it take for a full 30 LY jump range?  I'm thinking a straight Compact Core might be worthwhile...  8)

A 30 lightyear range on a primitive jumpcore is impossible.

The compact core warship would look something like this.
Code: [Select]
Invader Warship (compact core)
Mass: 150,000 tons
Technology Base: Inner Sphere (Advanced)
Introduced: 3145
Mass: 150,000
Battle Value: 960
Tech Rating/Availability: E/X-X-X-F
Cost: 6,424,340,000 C-bills

Fuel: 2,500 tons (12,500)
Safe Thrust: 1
Maximum Thrust: 2
Sail Integrity: 3
KF Drive Integrity: 5
Heat Sinks: 179
Structural Integrity: 15

Armor
    Nose: 7
    Fore Sides: 7/7
    Aft Sides: 5/5
    Aft: 5

Cargo
    Bay 1:  Small Craft (6)         2 Doors   
    Bay 2:  Fighter (6)             2 Doors   
    Bay 3:  Cargo (31025.0 tons)    1 Door   
    Bay 4:  Cargo (31025.0 tons)    1 Door   

Ammunition:
None

Dropship Capacity: 3
Grav Decks: 1 (65 m)
Escape Pods: 13
Life Boats: 0
Crew:  13 officers, 62 enlisted/non-rated, 1 gunner, 42 bay personnel

Notes: Mounts 40 tons of standard aerospace armor.

Weapons:           Capital Attack Values (Standard)
Arc (Heat)     Heat  SRV     MRV     LRV      ERV    Class       
FRS/FLS (8 Heat)
1 Large Laser   8    1(8)    1(8)    0(0)     0(0)   Laser       

Which is, you know, better from a purely hard stats perspective, but it's also sucking production of compact cores away from the military. IIRC primitive cores can be produced with a much less advanced techbase which means more options of where to build it, more places can build it, and it can be built by smaller outfits. Primitive jumpcores are terran alliance level tech.

Also, if you're building a straight warship which looks like it's gonna be able to actually fight, you know that yard is getting bombed sooner or later.

Interstellar Operations, page 130 says:
A 30ly primitive jumpcore is 144,400 tons.
A 1/2 transit drive is 9120 tons

This takes up 153,520 tons out of a 152,000 ton mass budget.
That's not including structure, sail, control, heat sinks, crew quarters, or anything else.

I thought you could put a station keeping drive on primitives? ???

I have no idea. Though if you could, the machine I puzzled out on paper would be losing most of the structural integrity, armor, cargo, fuel, hangar space (dropping back down to just two smallcraft), and all but one hardpoint, and at that point, you might as well just take a normal Invader and drop two hardpoints.

I think that was the point of the Primitive core rules... their ultimate evolution was just a standard core.
