And we are told that only starting the drive is detectable (and that is probably within a certain distance, certainly with something as small as a g-torp), but it hasn't been specifically stated that a spider-drive is detectable simply because it is maneuvering. Other than perhaps exposing its proposed less stealthy side. And I do not think it is a given that a spider-drive has to be shut down while stopped, unless it would be idling for weeks.
And of course the fuel needed to loiter would be figured in the equation. As Jonathan implied, and I concur, it would depend on the distance launched and the intended time of attack. It should not be too much to expect the natural fuel supply of a g-torp to be able to deliver several days of loiter time, especially for an attack launched from an LD that has somewhat infiltrated the system.
tlb wrote:Where were you planning to loiter? If near the target (waiting for other things to get in place), then you have to worry about light speed detection: thermal imaging, occlusion detection and so on. If far away, then better planning could eliminate that step. Remember that you need to power a three-second graser which uses so much power that it completely destroys itself and its vehicle. What you must absolutely avoid is having insufficient power to accomplish that last step. No one is going to build in a loiter phase, if they do not need to do so. It increases size and complexity, when size is already a problem; so yes, it is too much to expect. The Silver Bullets were substantially bigger, even with the trickle charger.
PS: No LD was involved. Also it gives the whole game away if the only way this could be done was to use the spider drive.

But I think it has enough reserve than you think, certainly for an ordinary attack. Think about it. It has to. Any missile must not only have enough fuel remaining to execute its attack run, but it must have enough fuel to dodge obstacles as well (like Foraker's triple ripple). Do consider that a g-torp’s main duty as most of us suggest is to be launched from the edge of the system. In that tactical scenario, a lot of objects – insignificant warships, school buses, yachts, dispatch boats, news crews, and even entire fleets – can find itself in a g-torp's way. A g-torp may have to vector way off of its intended flight profile just as GR platforms must frequently do when they are spying. If a g-torp's energy budget is “just enough” the normalities of life caused by Murphy would make it useless.
But we cannot compare the loiter time of a Silver Bullet which I assume is measured in weeks to that of a G-torp which, again, several days or even a day is not too much to ask. And again, if launched from much closer in from LDs then Bob is still your Uncle. But if that power budget is increased ... tum te tum tum tum.
In summary, without the ability to loiter then there also isn't much ability to maneuver, and falling short on either could expose the entire operation. Oops!
I think that that you are adding a wish list, instead of keeping it simple. I am not saying the energy budget is only "just enough"; I am saying that it is absolutely necessary to have an over abundance of energy at the end, rather than too little. I think it is you that wants to only have "just enough" power remaining to take the shot. It does not take anywhere near the same amount of energy to maneuver, as it does to come to a complete stop and then perhaps accelerate again.
PS: Wasn't it a G-torpedo that ran into the wedge of a tug, since the ship yards were much further out?
Again, I think you are missing a lot of variables. I won't specifically argue whether a g-torp was originally designed with loitering in mind, because I think the ability would be a by-product of ensuring sufficient maneuverability to be useful, which would render the issue moot. In the early days of missiles what was more important than having enough power for an attack run was being able to reach the target in the first place. Which gave us varying stages of SDMs, MDMs, and my own proposed NIMMs. (Near infinite mass missiles
).
Remember my constant preaching that the strategy and tactics that must be considered are completely different across the board for MA weapons? Then consider the life of a weapon as slow as a g-torp launched from the edge of the system. If the MA can take a snap shot of the system at the time of launch, I'd bet that snap shot will look nothing like what it did at the moment of launch. So a g-torp
must have the inherent ability to perform extreme maneuvers to prevent collision or detection.
Consider our smart phones. We have battery saver mode, extreme battery saver made, the ability to kill background apps, lowering the display screen, etc. I would imagine a g-torp has an onboard computer that can make decisions on the spot to do the same. We do not know all there is to know about a spider-drive. A spider-drive may have a low power mode while coasting. The low power mode could not only save energy but reduce waste heat.
At any rate, the ability to loiter would be a by-product of increased maneuverability. Loitering saves energy and again reduces waste heat. You don't think the MA would look into loiter time for a stealthy missile? I think they'd be irresponsible not to.
At any rate, exactly why would the ability to loiter increase the size of the missile? I also fail to see why decelerating would require significant amounts of power. And again, loitering may have its sweet spots. Better to loiter in suburbia than in the middle of the ghetto. Or vice versa. LOL
Also, after loitering, getting a g-torp back up to speed shouldn't take that much energy, IMO. It is already a slow missile. Almost as slow as an LD. I imagine a g-torp reaches its max acceleration very early after launch, so a restart after loitering shouldn't require any significant power, nor would there be a rush to get back up to speed.
Isn't there a thread currently trending about the various power modes of wedge based missiles? Why would the same notion not exist for MA missiles?
PS
Why did the G-torp run into the wedge of a tug? Where did that happen? Was it intentional suicide by the g-torp because of its drained power reserves, to prevent detection or due to a malfunction?
