Welcome to Star Trek Answers. What would you like to know?

It's most likely the shields weren't fully charged or they didn't come up in time.

they dont take long to charge, in nemesis, riker orders the shields up when shinzon takes picard, and they are instantly up. and usually, in most episodes, shields can't defend the ship from collisions. actually they can because also in nemesis, when the first warbird gets hit, when the debris hits the enterprise, the shields take the damage. so idk........

They retconned the way shields work. There was this one episode of Voyager where a piece of debris was levitating on top of a planetary shield, just like a giant force field and just like you would expect shields to work, but for some reason they changed this for the movie. 19:02, November 27, 2011 (UTC)

Well, shields are primarily for absorbing energy damage. Aka beam weapons or even torpedoes don't have that much explosion strength sometimes. Deflector shields are the ones used for protecting the ship from impacts. They aren't as strong. Plus, it's Star Trek 2009, how realistic is that movie? And we're talking Star Trek realistic here!

Also, remember the case of the Jem'Hadar ship ramming into the USS Odessy?

They were 23rd century shields protecting a 23rd century hull. The shields likely weren't able to able to absorb all of the force involved in the collision like they did at the Battle in the Bassen Rift. The Enterprise-E was able to able to absorb the full force of the collision with only damage to the shields. The warbird debris were also smaller than the debris of the ship the Enterprise ran into in the Battle of Vulcan. The weaker shields, weaker structural integrity fields, and the larger debris involved in the collision the Enterprise was in during the Battle of Vulcan resulted in hull damage.

Nah, the energy involved in a low speed collision (the relative speed was low) is minute compared to that of a photon torpedo detonation. If shields can handle the latter they can certainly handle the former, even 23rd century shields. 20:24, November 27, 2011 (UTC)

Agree on the 23rd century shields protecting a 23rd century hull. but we also should include the fact that the ship that nero had. it contained temporal abilities. so for a less of an argument. its like the Enterprise e picking a fight with the Enterprise C. soo we have to take into consideration that his ships fragmentation torpedoes (or whatever they are called) were superior in design to the ship.. also that ship was a Romulan Mining Ship. soo it has to have some heavy ordinance to assist in its function.



Shields are primarily designed to defend against energy and radiation as opposed to matter. So because debris is matter there is always a chance that it can pierce portions of the shield grid. So shields protect from energy in the terms of objects that's the deflectors job. Ionization also plays a factor

Because no matter how powerful your shields are, it's a tough task to stop 20 tons of space metal in it's tracks. The momentum that it's carrying, either leftover from the (former) ship's thrust or the force of a ship-breaking explosion, added to that of your own ship, coupled with the mass of the debris means it's probably going to buckle your shields and hit hull.

Quite simply, the inertial energy of such a large and fast moving chunk of ship is greater than the energy generated by your warp core, let alone that which is channeled into your shields. 08:40, November 28, 2011 (UTC)

Negative on the two posts above: if shields are bad at stopping physical objects then they wouldn't protect against photon torpedoes, also the force fields in the brig wouldn't be able to keep a person inside a cell.

Kinetic energy at non-relativistic speeds (and the speed was clearly non-relativistic) is minute compared to the energy release of a photon torpedo detonation.

Conclusion: it's bad writing and retconning that now makes the Enterprise vulnerable to even the weakest kinetic weapons. It's just stupid, just like traveling from Earth to Vulcan is half an hour is stupid. 11:13, November 28, 2011 (UTC)

As anyone who read "Countdown" would know, Pike was never meant to be captain of the Enterprise, and everyone on board knew it. Therefore whenever Pike gives an order, the employees all just mutter something sarcastic under their breath, or in the case of Spock, try to make him look bad in some other way. No one ever put the Enterprise shields up.


The above comment is complete bull. that was never mentioned in countdown.

As seen in The Wrath of Khan, 23rd century shields take a moment to activate fully


To clarify on physical debris and its impact on shield grid it is possible that an object of great size and or density moving at a high speed could pierce a shield. Photon torpodoes don't make physical impact with starship, these torpedoes are like grenades in that the damage they deal is from the energy released not the physical impact of the container. An individual inside a starship's brig is not of substantial size, density or moving at relatively high speed. Now it must be noted that shields can protect against debris, this was never denied, what was mentioned was that shields are designed to protect against energy weapons thus they protect against energy most effectively.

Conclusion: Even shields are fully charged they can be penetrated.

Shields are most effective at repelling energy not matter.

Giant things are hard to protect a ship from.Darkseid253 06:11, December 7, 2011 (UTC)

A photon torpedo moves a lot faster than that piece of debris and since kinetic energy equals 0.5*mass*speed squared this can easily make up for the difference in mass.

Yes we know a Jem'Hadar attackship at high speed can ram through the weakened shields of a bird of prey but that's a whole other order of magnitude of kinetic energy, may involve the attackship's deflector working as some kind of shield jammer and, as mentioned, it is preceded by using energy weapons to weaken the shields during the attack run. 10:45, December 7, 2011 (UTC)

Once again photon torpedoes do not and are not designed to deal sizable damage through impact ie kinetic energy. The annihilation reaction is what does the work not the casing kinetic energy is never a factor in photon torpedos.

On the Jem'Hadar attack ship it doesn't have to be going all that fast to pass through shields. You see a shield system is a grid with emitters all working to gather to repel objects and so if those individual emitters become stressed they cease operation. The reason why the Jem'Hadar ship can crash and destroy even a galaxy class ship is because in order to repel the oncoming vessel the emitters must channel higher levels of power in a considerably shorter span of time and they are not meant to do this. The crashing ship overwhelms the shield grid

The only time we saw a Jem'Hadar attackship ram a Galaxy class was when the shields of that Galaxy class were already down. Photon torpedoes carry massive amounts of kinetic energy, yes, their warhead yields even more energy but that doesn't take away from that kinetic energy. A 100kg photon torpedoe impacting at 2000kph (slower than many existing missiles) would have 60% more kinetic energy (which would also be packed in a needle-like small surface) than a 100ton piece of debris traveling at 50kph.

If a piece of debris can penetrate shields then so can a photon torpedo, let alone a 5ton shuttle at a quarter impulse (much faster than 2000kph) packed with photon torpedoes. That would mean any pirate or Maquis raider could cripple the largest warship if they have a shuttle with them. 12:13, December 8, 2011 (UTC)
