Single and multiple warp nacelles
As of late several of our players in the last month who have designed ships that are noted with having one, three, four, and five then even a six nacelle designed vessels. This had become an out of control problem of some truly goofy looking starships and spacedock designs. I really don’t care what the design is or looks like until the design gets too out of balance in the game terms and gives a too big of advantage to one side.
The single nacelle versions of the starships have been around for more than three decades (Saladin/Hermes-classes) and the same with the triple nacelle design (Federation-class). In the past we have played with these vessels and even just recently we played a three interconnected missions with a Constellation-class, however I have never allowed more than four nacelles in the design.
To simulate single- or triple-nacelle designs or even more nacelles, the following optional rules I have generated out of similar ones found on this forum for the Coda system that someone expanded out. I made changes to the system to facilitate its use in spacedock. Their hand drawn sketches looked cool but in combat I decided that they were given an advantage that the others did not have.
With the following rules that we have instituted below are the rules and examples generated out of a standard Galaxy-class Explorer nacelles. I have altered the nacelles to show the versions changes in the SU’s cost.
Example: Base line
Twin Warp Drive Nacelles: Type 6D <105>
Speed: 6.0/9.2/9.6 [1 power/.2 warp speed]
Special configuration: Standard two nacelles
PIS: Type G (10 hours of Maximum warp) <14>
Single-nacelle Warp Drive
• Costs 75% of SU’s for that of a standard twin-nacelle system.
• Additionally, the reduction of one full warp speed factor – 1.0 (the single warp factor reduction can be broken down across the standard/sustainable/maximum such as -.3/-.3/-.4 or some similar combination or even all to one of the three, the decrease cannot be higher than the standard/sustainable) or the lack of reliability at 75% of the PSI’s maximum speed (if a Max hours is 4, after three hour the difficulty increases by one)
• Damage to the nacelle reduces warp speed to zero from first hit with what is called a plasma disruption whether there was a plasma breach in the hull. This assumes that there was no significant damage to the nacelle.
Example
Single Warp Drive Nacelles: Type 6D <105 – 26 (26.25) = 79>
Speed: 5.7/8.9/9.2 [1 power/.2 warp speed]
Special configuration: Single Warp nacelle
PIS: Type G (10 hours of Maximum warp (difficulty +1 after 7 hours)) <14>
Triple-nacelle Warp Drive or more
• Costs 25% more per warp nacelle beyond than SU’s for that for a standard twin-nacelle system.
• Additionally, speed increased by point one warp factor of speed per category (the point one warp factor can be spread across in whatever formula but suggests the increase across the standard/sustainable/maximum such as +.1/+.1/+.1 the increase cannot be higher than the sustainable/Maximum).
• With the extra warp nacelle I suggested that an automatic two hours of maximum warp speed is a given.
• Note the Number of extra nacelles do accumulate bonuses beyond that the addition of a single nacelle. But an additional one hour of maximum warp speed per nacelles up to five nacelles. But exceptions to the rule will be allowed if the design and operation is feasible and makes sense.
• Damage to the nacelle reduces warp speeds to by seventy percent from first hit with what is called a plasma disruption whether there was a plasma breach in the hull. This assumes that there was no significant damage to the nacelle.
Example
Triple Warp Drive Nacelles: Type 6D <105 + 27 (26.25) = 132>
Speed: 6.1/9.3/9.7 [1 power/.2 warp speed]
Special configuration: Triple nacelle, two (one port and one starboard,) one nacelle centerline and high.
PIS: Type G (10 hours of Maximum warp (+1 hour to triple nacelle)) <14>
Example
Quad Warp Drive Nacelles: Type 6D <105 – 27 (26.25) = 159>
Speed: 6.2/9.4/9.8 [1 power/.2 warp speed]
Special configuration: Quad nacelle design two port and two starboard high and low of the secondary hull.
PIS: Type G (10 hours of Maximum warp (+2 hour to Quad nacelle)) <14>
The 9.99 taking up the extra .2 warp factor points that would have made the warp speed as warp 10.1 beyond the maximum warp speed for The Next Generation era warp speeds.
Embedded-Nacelle Warp Drive
• Costs 75% more per warp nacelle beyond than SU’s for that for a standard twin-nacelle system.
• Additionally, speed decreased by one per category (the Embedded warp factor reduction -.1/-.1/-.1).
• With the embedded warp nacelles I suggested that an automatic one hours of maximum warp speed is taken away.
This rule takes into consideration that the embedded nacelles are twin embedded or single embedded nacelles into a ship.
• Damage to the nacelle reduces warp speed to eighty-five percent from first hit with what is called a plasma disruption whether there was a plasma breach in the hull. This assumes that there was no significant damage to the nacelle.
• The benefit’s to the shields of +100 to the shield protection and +10 to thresholds.
• I usually force the incoming fire to have to burn the SU’s in Embedded Nacelles away before damaging the nacelles themselves and the rule of plasma disruption still applies to the nacelles.
Example
Embedded Warp Drive Nacelles: Type 6D <105>
Speed: 5.9/9.1/9.5 [1 power/.2 warp speed]
Special configuration: Embedded nacelles <32>
PIS: Type G (10 hours of Maximum warp (difficulty +1 after 7 hours)) <14>
Partly Embedded-Nacelle Warp Drive
• Costs 88% per warp nacelle under than SU’s for that for a standard twin-nacelle system.
• Additionally, speed decreased by zero per Standard, point one per Sustainable and point two for maximum. (The Embedded warp factor reduction -.0/-.1/-.1).
• With the partly embedded warp nacelles I suggested that an automatic one hours of maximum warp speed is taken away.
This rule takes into consideration that the embedded nacelles are twin partly embedded or single embedded nacelles into a ship the cost for the Partly embedded nacelles costing two times the SU’s.
• Damage to the nacelle reduces warp speed to seventy-five percent from first hit with what is called a plasma disruption whether there was a plasma breach in the hull. This assumes that there was no significant damage to the nacelle.
• The benefit’s to the shields for a partly embedded nacelles of +50 to the shield protection and +5 to thresholds.
Example
Embedded Warp Drive Nacelles: Type 6D <105 – 12 (12.6) = 93>
Speed: 6.0/9.1/9.5 [1 power/.2 warp speed]
Special configuration: Embedded nacelles <16>
PIS: Type G (9 hours of Maximum warp (difficulty +1 after 7 hours)) <14>
Twin sets of Warp Drive Nacelles
• Some Federation starships have been installed with the two complete Warp Drive nacelles and systems. These do not cost any different than a standard but SU’s cost for both sets of warp nacelles. There is a Nebula-class Prototype version that is this way and there may be others that are similar that I have not seen.
• The secondary set of Warp nacelles should not cost more than the Primary set of warp nacelles.
Example:
Primary set of Twin Warp Drive Nacelles: Type 6D <105>
Speed: 6.0/9.2/9.6 [1 power/.2 warp speed]
Special configuration: Standard two nacelles
PIS: Type G (10 hours of Maximum warp) <14>
Secondary set of Twin Warp drive Nacelles: Type 5.6 <53>
Speed: 5.0/9.0/7.6 [1 power/.2 warp speed]
Special configuration: Standard two nacelles
PIS: Type B (5 hours of Maximum warp) <4>
Other Warp Nacelles
• Retractable Nacelles still cost 3 SU’s and 5 power and 1 round to deploy as per Spacedock sourcebook.
• Variable-geometry nacelles still coat 5 SU’s and 5 power and 1 round to deploy as per Spacedock sourcebook.
• Embedded nacelles see above.
• Coaxial Warp Drive, Soliton Wave Propulsion, Quantum Slipstream Drive and Transwarp Drive Same as per Spacedock sourcebook..
All of the math is rounded up no matter how low of number are reached.
Personally, I think that more than four nacelles are just out of the realm of reality, but what do I know they could put a vessel with more than four nacelles in the next movie. As for the embedded nacelles I like the looks of a vessel with embedded nacelles or partly embedded nacelles like the Defiant, Saber and Streamrunner-class. Of the Triple nacelle designs the Federation-class and All Good Things Enterprise look good in the triple nacelles but pictures of the Excelsior and Miranda-class do not look as good. And the Quad nacelle designs such as the Constellation, Prometheus and Cheyenne-classes look really good and wish to see more. Yet, I am a traditionalist I like two nacelles but I have made several with the Quad nacelles and triple nacelles not to mention the how many with the Embedded nacelles. Like my other designs we keep it in the group that we use but when I will post in the future I will post as a standard version. I like these rules work best in the Original Series designs. The twin sets of nacelles I really don’t see the relevance in the design but respect the artistic design and there may be another thought behind the design. I still love the Nebula-class after all these years.
Let me know what you think of these rules. I was greeted with a mixed review of support and rebellion and nonchalant concern from our group. When it came to a vote over the rules they voted a majority of group to adopt the rules as written above. There is some of our group that don’t care what the changes in the rules are made, then some who think that any change is wrong and resist any changes, and the rest once the explanations are made they make up their own minds.
