That would be the first generation multi-drive missile Alice Truman used at Second Hancock.
Which is the Mk41, the original capacitor-driven multi-drive missile. (The designation shows up in HoS; and I think that might actually be the only place it's given)

Since the slug launcher is using gravity rather than high pressure gases or magnetic fields, the actual compression, tension and shear forces acting on the projectile should be zero. Of course the gravity launcher might not create a uniform field, so their might be tidal forces acting on the projectile.

That would be some advancement in robustity! Consider that what limits a missile's acceleration is basically how robust the drive, warhead, pen-aids and guidance packages; and that with the advantage of the drive's "compensator effect."

You're essentially suggesting launching the same missile warhead without the guidance, pen-aids and drive packages at accelerations higher than missiles can manage -- when theoretically can accelerate to light-speed instantly; IOW a theoretical acceleration rate of infinity.

If you can build a warhead robust enough to withstand the accelerations cited in this thread, why not mount the warhead on a missile with equally robust guidance and pen-aids and accelerate at that rate over a few thousand kilometers rather than mere tens of meters?

Of course, those gravity well forces are still transferred to the ship through the launcher in question.

Equal and opposite forces. Some force has to create a gravity well.

In addition, David has already noted that the primary limitation on the range of Honorverse energy beams is aiming and target location uncertainty. That will be just as true for your KEWs as for beams, so they will have the same limitation on range.


Except worse, because KEWs are slower.
They also take up physical space that is probably a lot more than the amount of fuel needed for the reactors to power a graser.

Even if you COULD reach high enough speeds with KEWs that is.

A point to remember about Honorverse KEWs. They are already single stage, variable acceleration, capacitor powered missiles with very precise controls. They are very short range and very accurate. Are you suggesting using these types of KEWs?

Hi everybody.
I have just been reading the posts here and a question came to me related to graser.
In another space series the problem of Laser weapons to pick is the diffusion rate in case of a miss.
Can anyone tell me how this is handled in the Honorverse, or are the energy ranges low enough that even if you miss you don't have to worry about anything behind the target?

No, the KEWs that people were promoting were unpowered devices (except perhaps for terminal adjustment) which were to be accelerated by the launching ship. Which we have shown is not plausible in the Honorverse.

Yes for the most part the graser is considered to have an effective range of a million km vs a ship after about 10 it is considered pretty harmless. Although people try not to shoot at a planet however if a planet were to get hit because someone moved then it is less a war crime and more an accident.

An actual multi-meter gamma ray laser would be deadly to a horoverse warship out to at least light hours, possibly deadly to soft target out to light months or beyond. The beam would be something like twice as large at a few light hours than it is a light second. It's unclear how the honorverse grasers work.

Okay,
thank you for the fast answers and clarifications.
