Nitpick Description


Submitted by Nitpicker : Anonymous
Movie : Star Trek: First Contact - 1996
Nitpick Category : Technological Fact
Nitpick Number : 27991
Approximate time of Nitpick : 3/4 of the way through
Summary : Impressive single-stage-to-orbit ICBM
Detail : This is my favorite scene in the movie, and the first warp ship is my favorite vehicle, so I'm just being picky here. The launch vehicle shown here is a Titan II ICBM, first flown in 1988. Not withstanding the fact that by the time the story starts the missile would be ancient, it also sports some impressive flight performance beyond its time. The real Titan II uses two stages to carrying a nuclear payload into low Earth orbit. For heavier payloads like satellites it requires two more strap-on boosters (Titan IV variety). In First Contact, it carries a three-person crew, in an incredibly spacious cockpit, and tons of warp equipment behind the cockpit. It is clearly only a garden variety Titan II from a silo, but flies into orbit (indeed even reaching escape velocity) using only the first stage. During the staging maneuver you can see that the 2nd stage motor only fires a short burst, they are already in space ! No launch vehicle today goes single-stage-to-orbit, without strap-on boosters (except the MD Delta Clipper, which is unfortunately cancelled during development).

So maybe it ISN'T a Titan II, but merely a launch vehicle that happens to look like it.

 

Mid-21st Century Modifications

While the exterior appears to be that of a late 20th century Titan II, the interior could be very different. The Phoenix was launched more than 60 year from now, by that time they could have figured out more efficient fuels, lighter building materials, and other techniques to allow the Titan to enter orbit in a single stage. Plus, I would assume that the man who was smart enough to develop warp drive could also figure out how to modify the rocket sufficiently.

 

Only need to deliver to vacuum, not escape speed.

The rocket doesn't have to reach actual escape - just an altitude sufficient for the warp drive to move the craft up up and away. A 268,000 lb Titan II first stage drops off about 40 miles up then coasts to a 75 mile apogee. If the 2nd stage didn't fire, it too would coast up to 75 miles. I imagine that the only requirement for the warp to kick in is to no longer be in the atmosphere and 75 miles would do that. A Titan II 2nd stage weighs 74,000 lbs and carries 8,500 lbs to orbit (Gemini XI). If they used a Titan IIIB first stage, add a 15,000 lb Agena between the payload and 2nd stage. That's 97,500 lbs lifting capacity. Apollo was 63,000 lbs and that was with 40,000 lbs fuel, and it was 3-man. Also, the first Titan II flihts were around 1962 not 1989. 1989 was the first use of surplus ICBMs. All twelve Gemini flights between 1964 and 1966 used Titan IIs. Incidentally, a Titan II 1st and 2nd stage empty weigh 13,000 and 5,500 lbs.

 

Inertial dampeners

One of the necessary components of a warp ship is the inertial dampener. One of the reasons for this is to stop the pilots being turned into a small pile of mush when he ship accelerates to warp (1c). But a secondary effect is to effectively lower the total mass of the ship. So it has the thrust of a Titan II but may only weight half its normal weight thus allowing it to get to orbit in a single stage.

 

Where's the fuel?

This is a valid nitpick. In addition to making it to orbit on one stage, where are they keeping the fuel? The nacelles are stowed where it normally would reside. More importantly I guess, what kind of fuel are they using that would both take up little space and get the thing into orbit in one stage?
