| The way in which DoD identifies needs and subsequently develops, tests, procures, and sustains weapon systems has evolved over time. Today's acquisition foundation can be traced back to the Packard Commission report in 1986, where many of this report's recommendations became part of the Goldwater-Nichols DoD Reorganization Act of 1986. This evolution continued along three tracks: (1) Requirements moving from threat-based to capability-based, (2) The resource allocation system adding execution ... |

|
| Most conventional weapons rely on chemical energy (explosives) as their destruction mechanism, either to explode on target, like bombs, or to create kinetic energy, like a bullet. Electric weapons are different. Electric weapons use stored electrical energy, rather than explosives, to attack or destroy the target. Electric weapons generally fall into two categories: directed-energy weapons (DEWs) and electromagnetic (EM) launchers. DEWs send energy, instead of matter, toward a target, and ... |

| Not long ago, around the mid-1980s, development of most new mechanical systems such as automobiles, consumer products, and military devices was performed manually on a drafting table or drawing board. Engineers used them to prepare layouts or 2-dimensional sketches of what they were designing. They then would take these layouts to a draftsman, who would create drawings of each part in the device. The drawings would subsequently be sent to ... |

| Solid state lasers are one of the candidates for efficient and compact directed energy systems. To achieve the necessary power levels many laser beams must be combined to form a single focused beam. We discuss coherent and incoherent combining of multi-kW, high quality lasers and the effects of atmospheric turbulence and aerosols on the propagation of the combined beams. We analyze the beam centroid wander and spreading contributions to the ... |

| Directed energy weapons will dramatically increase naval capability by offering extreme precision, scalable power, speed-of-light engagement, and a nearly limitless magazine. Precise beam control is essential for maximizing the energy on target and damaging the target structure. Directed energy weapon systems operating in a maritime combat environment, however, will be mounted on dynamic platforms that are subject to jitter-inducing mechanical vibrations. Jitter is any deviation of the beam from its ... |

Matthew L Roberts; NAVAL ACADEMY ANNAPOLIS MD
|
| To mitigate jitter in a directed-energy laser system, caused by mechanical vibrations without feedback from the target, a feedforward compensations technique is proposed. The technique requires that the position of the beam at the target be calculated in real time, which is accomplished by determining the exact position and orientation of the platform that fires the laser beam. Once the position of the beam at the target is calculated, it ... |

| Calculating the reflected irradiances produced by a specularly reflecting object at many observation points is computationally intensive, the total computational load proportional to the product of the number of facets times the number of observation points. In order to capture specular glints at all observation points, it is necessary to finely discretize the surface of the object into a large number of facets. This can result in a massive number ... |
