No problem. The metalstorm experiments are in an early enough stage that they might develop in any of a number of ways, either one of those noted by either of us, or in others yet unforseen, as other materials and design possibilities are considered. Disagreement is welcomed, for from such considerations of the full spectrum of facts come the necessary compromises which design engineers have to face and deal with.
That too will have to be balanced against other related developments; the OICW program, for instance, which the Metalstorm technologies might either compete against or mesh with; we shall see.
But as for the Navy's consideration of discs in flight, ranging from frisbees to clay pigeons to illumination flares, that is not supposition: I was an ordnance employee with FLSD NavWepSupCom at the time and I was there. And the ring airfoil grenades are also an existing, proven technology, though not greatly advanced beyond the prototype stage, so far as I know. Both are certainly more fully developed than Metalstorm, which despite their swell public relations capabilities, are certainly not yet capable of being fielded as practical tools. Whether Metalstorm can also overcome the notorious NIH factor in American weaponry and equipmebnt development and procurement remains to be seen as well.
