First jump-capable Survey Ships
« on: February 13, 2017, 01:20:51 PM »
After 42 years since conventional start we are finally getting to other systems.

I used the smallest usable jump engine but the limit still allowed for a full assortment of sensors in case it meets someone out there. Engine is boosted from 0.25 to 0.35 so it has bit more power and with 6 systems around Sol to to explore before moving further the 2.5x lowered 100b range seems quite enough.

There is exactly one small engineering section: it allows for no failures, is not a cheatily small fighter size but doesn't offer any damage control of standard size. That's current doctrine for all commercial vessels. Similar reasons are for setting higher deployment time.

Note our researchers are still in the state they are only wondering what CIWS could mean so no commercial autodefence. That's the only idea I have for later. Possibly. But so far no contact ... so no need for it either, eh?

Do you see any issues with this design?

No real problems, except for armor level. Usually have 2 layers for early jump ships (for more than just enemy fire). Also not quite enough oomph in the engines because of some... hazards you may encounter in space (not talking about enemies, if you don't know what I mean then I wont spoil it).
Give a man a fire and he's warm for a day, but set fire to him and he's warm for the rest of his life.

OK, I will wait what we may uncover. Because, actually, though no proper contact was so far made there are two 20k-ish wrecks at Alpha Centauri. If that was not just a traffic incident the thing that got them may be still be around... be it of physical or biological kind.

With the troubles of jumping I am starting to see the proper value of hangars and normalized ship sizes.

OK, it fitted with 2 layers of armor in grav variant after while. Still slightly sad you can't just switch grav sensors for geo sensors and be done.

Desired doubling of engines lead to it guzzling 6 times more then geo does. But with the pricetags on research of bigger jump engine designs so high it may take some time before I get decent rescue carrier through a jump point so loss of only engine would be quite undesirable.

While surveying system third system of the initial six around Sol I have met other race ship. Armor 2 would not be enough as they apparently have 10 damage missiles.
Dispatching welcoming committee to the jump point.

It bugs me that it's not an even 4000 tons. If you add anything to fill out the tonnage then you'll be able to use it for a jump tender for 4000 ton designs long after the ship becomes obsolete. If that kind of thing interests you.

". . .  We know nothing about them, their language, their history or what they look like.  But we can assume this.  They stand for everything we don't stand for.  Also they told me you guys look like dorks. "

After I noted the sensors seems to work like "1000 tons or bigger" or "5000 tons or bigger" most of my ship classes are just 1 HS under such rounded value. Frigates at 4950t, destroyers at 9950t...

The strength of this doctrine is bit weakened by our hostile neighbours seeming to use R84 sensors and not R100 ones.

Those sensors would still be able to spot you. The "1000 tons or bigger" only refers to the maximum range at which they can notice a ship of that size. A sensor can still spot smaller ships, but at reduced range, following this formula: Detection range = Max Sensor Range x (Target Size / Resolution) ^2

So a R80 (4000 tons) sensor spotting your survey ship would have its detection range modified by a factor of (3950/4000)^2 = 0,975

I don't think that is worth it.

Argh. I thought the difference would be bigger.
What's more those neighbours seem to have radars with 180M km range so... few percents won't make it.

On the brigth side if they use r84 they'll get 0.88 range against your 3950 ton ships.

Nice.Thought as far as they stay on their side of JP the radar range is not too important. Because, as two scouts have very closely found, there are now three rocket ships camping the JP. Working on technology to get past them...

Giant armored bulwarks. Can even be a commercial ship without weapons or military components with 18 or so layers of armor and CIWS.

No CIWS researched yet, I have just lasers and mezons. But 45kt jump tender is already in preparation.

Here's me first jump-survey ship . . .  and currently still my only jump-capable ship in my first game.  (I seem to have little time for anything except churning out automines and still haven't designed a jump tender to get extrasolar colonies established. )

Code: [Select]
Northumberland class Gravitational Survey Vessel    15 000 tons     264 Crew     1633 BP      TCS 300  TH 420  EM 0
4000 km/s    JR 1-50(C)     Armour 1-54     Shields 0-0     Sensors 110/80/2/2     Damage Control Rating 19     PPV 0
Maint Life 4.47 Years     MSP 1293    AFR 94%    IFR 1.3%    1YR 105    5YR 1570    Max Repair 175 MSP
Intended Deployment Time: 42 months    Spare Berths 0   

JC15K Commercial Jump Drive     Max Ship Size 15000 tons    Distance 50k km     Squadron Size 1
400 EP(.035)-TR35 Com. Magneto-plasma Drive (3)    Power 400    Fuel Use 3.54%    Signature 140    Exp 5%
Fuel Capacity 1 000 000 Litres    Range 339.0 billion km   (980 days at full power)

Thermal Sensor TH10-110 (1)     Sensitivity 110     Detect Sig Strength 1000:  110m km
EM Detection Sensor EM10-80 (1)     Sensitivity 80     Detect Sig Strength 1000:  80m km
Gravitational Survey Sensors (2)   2 Survey Points Per Hour
Geological Survey Sensors (2)   2 Survey Points Per Hour

This design is classed as a Military Vessel for maintenance purposes

I figure the design was pretty inefficient without even a decent passive sensor suite, but I was able to survey two full systems before I needed a maintenance overhaul.  It'll be dead meat if it ever runs into trouble.

Oh, Holy mackerel!..
Most of my cruisers was cheaper, then this Northumberland class survey vessel!
