Okay, so as far as Tinker ideas go.
Since Simus is likely to create a better fusion warhead, I think Anton will still want to see his weapon realized - even if in a smaller form.
So, taking the original Token of Appreciation idea (I really need to come up with a less unwieldy name for it), it can be made it a pretty effective manpack missile.
"Hammerhead" sub-nuclear offensive warhead
Form-factor: 65x980mm spin-stabilized missile
Propellant: Standard self-oxidizing solid fuel mix
Payload: 200 grams Aster-Ex, 2x kinetic amp ("kinamp sandwich" setup) as initiator.
Choice of: direct impact plate, 1500 grams shaped tungsten carbide pellet filler, or 1800 grams depleted uranium shaped penetration slug, as contact medium.
Detonator: Choice of impact fuse, proximity fuse, and/or command detonator.
Operation: Missile self-stabilizes following launch using deflected exhaust gases to impart spin. 500 milliseconds after leaving the launcher, the missile is armed. Upon receiving detonation signal, the 200 grams of Aster-Ex explosive detonates, pushing the contact plate of the kinamp-sandwich initiator forward, crushing the mineral foam padding within the sandwich, and imparting the force of the explosion and the momentum of the missile into the first kinetic amplifier. The force is amplified, and transferred into the second kinetic amplifier, where it is amplified once more, and transferred into contact medium. The magnitude of the forces involved releases a significant amount of energy in all directions - shooter is advised to take cover if at less than medium range.
If equipped with direct contact plate, warhead transfers all energy directly into target, imparting significant momentum to outer layers of its surface, potentially causing massive damage, but limited by the composition of the surface struck.
If equipped with depleted uranium penetrator, warhead transfers energy into the penetrator, partially melting it and imparting it a velocity in excess of 2000 meters per second, ensuring massive armor-penetrating damage regardless of target composition.
If equipped with tungsten carbide pellet filler, warhead creates a cloud of superheated metalloid debris moving forward in a 60 degree cone at speeds in excess of 2000 meters per second, ensuring a wide area of effect and massive damage to soft targets, regardless of their thermal protection.
Primary advantage: Unlike conventional explosive and nuclear weapons, leaves the shooter in far less danger than the enemy due to the directed nature of the resulting explosion.
Disadvantage: High cost... what else? Token costs of approx. 10 per missile, production costs unknown.
