Re: Making Gyrocs Great
Since there's some control over velocity how about a Slow Gyroc, One that caps out just under the speed of sound with a very massy projectile? chances are you wouldn't get much range out of it due to the speed but with a round that accelerates rather than decelerating you could pack a whallup without breaking the sound barrier, maybe the round would be big enough to contain a chemical payload or a super-heating core or some other fun gimmick that would be useful in a silent weapon.

In general 'silent' and 'rocket' don't go together, unless you're willing to use an extremely low performance rocket. |

This might not make it appreciably quieter, however - I'm pretty certain the exhaust would still be supersonic. Slow gyrocs would be used more to get extra range, so would probably be micromissiles. I'm not certain what the stall speed of a gyroc would be, but if you can get it down to 100 yards per second, that'll let it fly for around 10,000 yards (over 5.5 miles) but will drop the damage all the way down to 1d+1 pi++, so you'll very much want to make certain you pack the warhead with something that'll do the job for you. In theory a slow gyroc would let you get away with less robust engines, but I'm going to ignore that (I'd expect normal gyrocs to have normal engines that they push to the limits, and anything cheaper is going to be less reliable, which you don't want). Note you could combine this with Flight - a 0.2 lb snail flight micromissile would cost $20 plus the cost of the guidance system (probably $150 for Viper, for a total of $170) and warhead, and fly for 30,000 yards. It would have Range 30,600/33,600*, but would only fly at 100 yards per second, meaning it would take up to 5.6 minutes to reach a target at maximum range. *As GURPS typically modifies range with the power of the round - specifically, scaling it linearly with damage for a given caliber - so adhering to +600/+3600 may not be appropriate. In this case, it would be +120/+720, for Range 30,120/30,720, which could probably just be rounded down to Range 30,000.

The overall problems in UT come from 1) ETC weapons being just that good (and perhaps unfortunately RL research doesn't rule that out as a reasonable assumption), and 2) all warheads of the same calibre having the same payloads. A gyroc round intended for delivering a payload, rather than a KE-based round, could have a relatively low velocity (and long burn time to keep the range up) and thus a large payload compared to a rifle. That would make them a more accurate, but direct fire only, equivalent of a grenade launcher. Unlike a grenade launcher, you would have the option of high velocity, high-KE damage, rockets with shorter range. Another thing is happily allowing homing rounds from rifles at the same calibre as for gyrocs, despite the harsher launching environment.

Re: Making Gyrocs Great
Current small arms, sure. However, it's in the same ballpark as modern tank guns.

https://en.wikipedia.org/wiki/Gyrojet and maybe the Buck Rogers rocket guns. As a rocket-launching platform, it probably has a much lighter construction than the image you linked to. Luke |

Re: Making Gyrocs Great
You can see some gyrojet test shots in this video, although they're using vintage ammo.
