Non OTU: Posting here to avoid the not invented here myopia

warwizard

SOC-13
Greetings this thread is to solicit ship designs for a Terran pre interstellar wars campaign using T4 FF&S designed ships for the Terrans. Some T5 elements may be used such as the QREBS system, which is encouraged as most Terran designs of this time should be concidered experimental.

This is for a IMTU campaign the following restrictions are in place for the Terrans:

TL=9 this is the default tech for Jump 1 but as we just got Jump 1 at the start of this campaign you may concider that we are mostly at TL=8 with some experimental TL-9 items. We may deploy any technology currently seen in the space programs of earth, and perhaps extrapolate a bit from designs that have not flown as of today, so rockets, Nuclear Thermal Rockets, Ion Drives, Advanced Ion Drives, Orion Drives, and it's fusion relative. Fusion rockets, Solar sails. Any drive system documented from NASA or ESA or their competetors can be used, just link the public documentation and we'll figure out the thing's performance in game terms.
The Terrans Have Fusion Plus, but it's still at the tea kettle stage, it generates heat , boils water, steam turns a generator to produce electricity. Too bad boiling water stops the reaction so we have to have a high pressure section to generate the heat and a heat exchanger then to do the actual steam generation, so it's a fusion power plant with stats identical to the ones published in table 218, (including minimum output), we just do not have a magenetic bottle and hot plasma at the core of our fusion plants, just an array of plladium electrodes in pressurized heavy water. Yes our fusion plants do go Boom when hit, it's a steam explosion as the heavy water flashes to steam when the pressure is released, not a fusion explosion.

No gravetics, Have not invented it, have no knowledge of it till the Benard's star expedition returns with evidence of gravetic technology in action. Thus long duration missions should concider the need to have environmental gravity for the crews. Ship either uses spin gravity or has a habitation module that spins seperate from the ship. As the campaign progresses we may obtain some anti grav tech from the cavemen. but that is for the role playing to bring home that goodie. :)

The Terrans are inexperianced with Jump space and of refueling directly from a gas giant atmosphere: (we lack the shielding systems that allow us to go near the gas giants and their radiation belts) Hull minimum armour level is set to 1 for habitible areas of the ship only. (think gold foil and aerogel for insulation) Our jump drives are of the "Jump Bubble" variety, so there is no requirement for a rigid hull to support a jump grid.

The Imperial ships are standard TL 11. War ships are designed mostly with missile space combat and lasers relagated to point defense roles. Some ship classes are bombardment only specializing in nuking a world from orbit.
Transport ships are designed per normal Traveller OTU conventions Class III life suport, floor plates providing artificial gravity, and g-compsentation for comfort. The Imperials will be locked into their ship designs and cannot change them during the campaign. They may produce ONE additional class of ships after the wars start, and that is the Fighter.

This is a Large ship universe: Scouts run to 1,000 Dt, Destroyers to 5,000 Dt, Light Crusiers to 10,000 Dt Heavy Crusiers to 20,000 Dt, Transports up to 20,000 dt

Next posts are for the mission specifications in the Request for proposals, written as in campaign documentation.

Terran System scout RFP

The winning design will have to show satifactory completion of all stages of the mission profile, with attachments showing the parts soursing and laying out the producibility risks for custom components. Competing designs will be evaluated and the top three will be taken to the initial prototype stage, Two designs will have prototypes produced and evaluated in a testing program, with the winning design entering full scale production and the losing design team entering limited scale production.

Mission statement:
A manned craft to travel up to 3 parsecs distant from the earth and spend no less than three months in the target system and then return to Earth. (All crew and mission specialists are to be returned alive and in good health.)
Tasks are to survey the target system and identify all planetary bodies to include any object 1000 Km in diameter or larger, obtain spectrographic, telescopic, electromagenetic, and gravemetric signatures from any planets and major moons located in the habital zone. All data are to be recorded and transmitted via tight beam laser to the nearest outposts and Sol system. This data stream will be a primary requirement, and is intended to provide data back to NASA should the mission come to grief.

The mission is NOT to conduct planetary landings, and the mission profile does not require the mission to orbit planets, though the mission commander at his or her discression may proceed to do that if the delta V is available to make orbit and still return to Sol system.

A Manned craft to travel to a target system up to three parsecs distant, orbit a target planet and conduct orbital and surface surveys in preperation for follow on colonization and exploitation missions.
Mission specialists to be landed on the surface with at least two vehicles with VTOL capability in standard and dense atmospheres which may NOT have free oxygen available.
At least one craft must be available to return the mission specialists to orbit along with up to 1000 kg of samples. There will be a seperate sealed habitation module for returning mission specialists and their samples, (to avoid bio contamination of the ship's crew).
This sealed habitation will include lab space for the mission specialists to use to perform analysis on samples as well as a fully stocked med bay.
The mission will then return to Sol system and deliver it's mission specialists and samples to a sequesterization lab for long term investigation and monitoring for any bio contamination.
All data are to be recorded and transmitted via tight beam laser to the nearest outposts and Sol system. This data stream will be a primary requirement, and is intended to provide data back to NASA should the mission come to grief.

A manned craft to travel up to three parsecs to a target system and safely land it's cargo and passengers on a planet with no local facilities, then return to Sol system for additional loads.
The passengers are to be provided metabolic hibernation treatments and woken from hibernation at the destination. OOC(Treat passengers as having been given Fast drug, and placed in a cramped seat for the duration of the trip, with the exception that they are hibernating not awake. Life support usage 60 people under hibernation count as one person active)

Mission volume is not to exceed 140,000 m3 and mass not to exceed 140,000 mt (10,000 dt cargo at 1 Mt per cubic meter)
 
Terran Colonial Transport proposal outline

Ok so proposal one for the transport ship:

Hull:
Open frame construction with no provision for atmospheric entry, and is currently planned to displace some 14,000 Dt, with 11,000 Dt being hydrogen fuel (another 1000 Dt fuel is carried aboard the fuel/refinery ships) Grapples for the colony landers are dry, there is no provision for power, people, or fuel to be transferred through the grapples. The fuel/refinery craft have full facilities in their grapples.

Engineering:
Jump 1 @ 40,000 Dt
Jump fuel for 3 parsecs (3X J-1 for 12,000 Dt of fuel)
Fusion power plant 2200 MW TL 9 to support 1 Jump 1 at 40,000 Dt
.1 g daedalus drive with 40 g hours of fuel at full load with all carried craft.

Environmental:
Full air and water closed loop recycling to class IV standard, food stowage for 1 year of operation, emergency rations are carried for a further 6 months supply. Hostile environment emergency shelters are packaged with the emergency rations and are intended to support the full crew complement in case of ship wreck for a period of six months.
There is a spun habitation module for the main ship's crew, and the colony landers are mounted far enough outboard that the colony landers are given 1 G through spinning the ship. (they are mounted with the grapples on their backs)

Sensors:
Astrometrics lab with planetary telescopes with variable computer controlled tracking 40 cm apeture and 16 megapixel CCD camera at the objective.
LHd cooled Infared scanner 20 cm apeture and 16 megapixel CCD camera.
Burroughs radar target data signal processor computer, .5 GHz to 21GHz tunable TWT transmitter 126 dbm with phased array 1m radar dish.

Communications: 10m dia laser emitter array for interstellar range communications. 3, 1 meter laser emitters for system level communications.
10 m Radio dish 100:1 FB ratio 100Kw power. Internal short range radio/hotspots.

Computational facilities: Three flight computers installed in triple rudandant configuration Two maintance computers in a double redundant configuration, 100 TB SAN with 4 compute nodes in double redundant configuration for the astrometrics lab. 6 bridge workstations 3 engineering workstations 1 environmental workstation, various handheld devices connected through doubly redundant hotspots.


2X 1000 Dt fuel/refinery ships
The fuel/refinery ships offload the fuel purifiers at the colony and use local water sourses and power from their fission plants to crack the water and cryogenically store the hydrogen. Fitted with airframe hulls and vectorable electric powered ducted fans the refinery ships are fully able to conduct VTOL operations in atmospheres lacking free oxygen. Orbit is reached using a NTR using the local atmosphere as it's working fluid (with some extra aboard in tanks to provide a vaccuum maneuver capability)
Note: that I am concidering making the fission power plant and the NTR be the same device, however this is a custom designed component and has some producibility risk. Backup plans are for solid fuel boosters and reloads for them to be carried, scaleing the boosters based on the planetary scouting report prior to launching the mission.

3X 8,000 Dt colony landers

The colony landers are placed into the proper glide path for entry into atmosphere by the main ship and are slowed by atmospheric friction to normal flight speeds where their wings and control surfaces conduct normal gliding flight. Solid rockets are carried in vectorable modules to enable a one time landing. The landers remain on the surface as simi-permanent housing for the new colonists folowing missions will carry landers that do not have the VTOL capability relying on the colonists to have built a suitible runway for glider landings. On board is a minimal sized Fission reactor to provide life support and some excess power for early industrial efforts.
 
Notes on crew accomodation standards

Terran ships will provide only the minimalist amount of space/volume to crew sleeping compartments. Designers are encouraged to cut corners on such accomodations, and place sleeping stations wherever it is deemed usefull without regard to foot traffic or operating machinery nearby unless it poses an active hazard to the sleeper.

Valani ships will have the utmost care taken into the design of pleasing and ergonomic spaces in all areas where the crew works, sleeps, and plays. The designer is encouraged to spend extra volume and costs to ensure crew comfort and harmonious surroundings, positioning sleeping areas away from noisy machinery or other disruptive activities. Crews are expected to have their children aboard so the accomodations and total number of persons aboard need to reflect that.

Oh, god, your Vilani are the Next Generation! Or the Honorverse's dark mirror of them, the Solarian League, possibly.
 
So, ship designs: google UPFS Challenger for Star Frontiers. I know it got reused for TSR Buck Rogers rpg site. It's Knight Hawks, no gravitics, thrust for gravity, and provides full deck plans.
Also, of course, 2300 AD.

Design for the TL 9 Terran Missile

1.0 Displacement ton (14.0 m3)
Armor 1 rounded cylinder 37m2 1.02 m dia by 5.12 m long stressed for 8.5 g's

.01 m3 fuel cell with Lhd and LOX fuel for 45 hrs 50kw output. .5m2 radiators

Minimum sized Fusion Rocket 1000.8 KN LHd fuel for 4 hours of thrust at 8.39 g's (fully loaded)

1000 Au laser communicator
Command guidance
Military Black and Basic EMM

Short range nuclear Det laser head 10Kt 50 DV DE 200

When the missile is thrusting with the nuclear rocket, the rocket generates electrical power to run the laser communicator. (TNE FF&S rule which does not appear in T4)

8.5 G's for 4 Hrs provides a powered intercept envelope of 291 hexes (291 X 30,000 km) with a 1212 Km/s terminal velocity.

The Fusion rocket is an obvious attention getter, however until the rocket is thrusting the Terran missile is quite stealthy: Vis sig -2, IR sig -2.5 Active sig 0
4.046 MCr in quantity.
