Can I get some feedback on some of my homebrew weapons from my setting?

SOM-HA
This disposable, handheld anti orbital weapon is not super effective for killing warships, but it can rip through weaker components and disable turrets. It can also rip apart fighters and shuttles attempting to come into atmosphere.

PPMP
This mounted particle gun might not inspire the fear and awe of a Fusion Gun but it is still a nasty weapon that can fry vehicles and infantry alike. it also releases lots of radiation, so don't fire without protection.
The gun has an Armor 6 Boron shield that makes the gunnery crew unaffected by the radiation trait

Space missiles

Conversion Missile:
This missile contains a small nuclear device that is detonated prior to impact in order to project a high velocity plasma "bullet". Due to the ‘stand-off’ nature of its attack, point defence against this missile suffers DM-2. Defences that work against fusion weapons can be used against this missile.

Enhanced Radiation Missile
A variant of the standard nuclear missile. It has a weaker blast but a far stronger radiation effect. Instead of doing 2D x 20 x 5 rads ( for spacecraft weapons) it does 4D x 20 x 5 rads to the primary target and 2D x 20 x 5 to every other ship in a 100 Km radius ( Short range band)

Space Torpedos

Conversion Torpedo:
This torpedo contains a small nuclear device that is detonated prior to impact in order to project a high velocity plasma "bullet". Due to the ‘stand-off’ nature of its attack, point defence against this torpedo suffers DM-2. Defences that work against fusion weapons can be used against this torpedo.

Enhanced Radiation Torpedo:
A variant of the standard nuclear torpedo. It has a weaker blast but a far stronger radiation effect. Instead of doing 2D x 20 x 5 rads ( for spacecraft weapons) it does 6D x 20 x 5 rads to the primary target and 4D x 20 x 5 to every other ship in a 100 Km radius ( Short range band)
