readersforum.Fuze fuze n. & v. Variant of fuse1. Noun 1. fuze - any igniter that is used to initiate the burning of a propellant fuse, primer, priming, fuzee, fusee Industry Concerns The President's Perspective issue (June 2001, p.4) of National Defense struck me, because fuzes have been an important part of my engineering career since 1947. In 1952-1953, I participated in a study concerning the high failure-rate of M-505 mechanical time fuzes under combat conditions. In 1962-1963, I contributed to the design of the M-223 impact fuze for the M-42 DPICM DPICM dual purpose improved conventional munitions (US DoD) grenade. In 1978-1979, I was part of a Government study to address the state of the fuze base of the new Electronic Time Super-Quick fuzes. In 1983-1984, my employment by a missile warhead house allowed me contact with the fuze-makers of Switzerland (e.g. Patvag and Tavaro). And, as recently as 1993, I consulted with an electronics house that wished to enter the ET fuze business - without success, I might add. This overall period was marked by two important situations. First, fuze designers were presented with ever increasing stringent safety and operational requirements (programming) operational requirements - Qualitative and quantitative parameters that specify the desired capabilities of a system and serve as a basis for determining the operational effectiveness and suitability of a system prior to deployment. in the military standard for fuzes. As with so many fields, a single incident involving death or injury generated a drive to eliminate all safety hazards. We strove to make the fuzes "fool-proof," but failed to make them "soldier-proof," and ended up (occasionally) making them "function-proof". Second, the fuze industry, as it was prior to 1975, was almost entirely an offset of the horological hor·o·log·ic also hor·o·log·i·cal adj. Of or relating to horology or a horologe. industries, especially regarding the mechanical out-of-line safe timers and the mechanical time air-burst fuzes for artillery. We all know what happened to that parent industrial base after the introduction of digital time-keepers pieces. By 1979, I was able, therefore, to ask about the MT fuze manufacturing capabilities, "What fuze base?" One approach to solving the problem stems from the insensitive munitions Insensitive munitions are munitions which reliably fulfil their performance, readiness and operational requirements on demand, but which minimise the probability of inadvertent initiation and severity of subsequent collateral damage to weapons platforms, logistic systems and initiative: Make the active elements so "safe" that electronic safety can be proved adequate to meet the properly stringent requirements imposed on initiating systems, thus rendering "dual out-of-line" safety and mechanical timers unnecessary. We grow closer to this goal, but the disappearance of skilled watchmakers and their like is matched by a disappearance of engineers at all levels who are motivated to exercise their skill in this arena. Instead, we have a plethora of managers who understand "cost-benefit ratio Cost-benefit ratio The net present value of an investment divided by the investment's initial cost. Also called the profitability index. " and "bottom-line," but who (in my experience) are ill advised as to the feasibility of some of the costly features they so glibly glib adj. glib·ber, glib·best 1. a. Performed with a natural, offhand ease: glib conversation. b. promote. And so I ask, again: "What fuze base?" Little has truly changed in the 22 years that have passed since I originated the question. W.L. Kincheloe MAGALIA, CALIF. Skewed skewed curve of a usually unimodal distribution with one tail drawn out more than the other and the median will lie above or below the mean. skewed Epidemiology adjective Referring to an asymmetrical distribution of a population or of data Historical Perspective David LL. Silbergeld makes a valid point (Bookshelf, April 2001, p.57). Many book titles covering events of World War II seem to be repetitive gimmicks to gain market share. However, it is speculation whether the Germans could have changed the outcome of World War II by making minor changes in their thinking. Those changes would have been met with Allied command counter-measures. In fact, Germany never had a chance to win the war in view of the 50 to one overwhelmingly combined resources of the British Empire, the United States and the Soviet Union. Furthermore, Silbergeld respectively has an obligation to know by virtue of his professional credentials (and assuming that he has no personal agenda) that Daniel Jonah Goldhagen's book represents nothing but junk-science that has been refuted by several reputable historians in this country and abroad. Goldhagen's politically fashionable junk-thesis follows the same pattern. Its regrettable that such a review found its way into National Defense. Historical events are like monochrome photographs containing many shades of gray. Interpretations of events are subject to personal hyperbole. I have mine. Eberhart Reimers PASCO, WA. Space Laser Congratulations on your fine article "Killing Missiles From Space; Can the U.S. Air Force Do It With Lasers?," (June 2001, p.16). The Space Based Laser is a highly successful program with strategic implications. It deserves coverage. Programs like the Space Based Laser need robust funding. It will provide boost phase interception and global coverage--qualities lacking in the National Missile Defense National Missile Defense (NMD) as a generic term is a military strategy and associated systems to shield an entire country against incoming Intercontinental Ballistic Missiles (ICBMs). The missiles could be intercepted by other missiles, or possibly by lasers. ground-based interceptor. Unfortunately, at $138 million annually, the Space Based Laser is under funded. We ate spending only 5-10 percent of what is needed for deployment. And the SBL SBL Society of Biblical Literature SBL Symbol Technologies, Inc.

SBLs will be large and heavy. But policies of "pretend to defend" will not meet the ballistic missile threat. We need to fully fund missile defense programs taking maximum advantage of space. We are only kidding ourselves if we think ballistic missiles will not be in use before 2020. In addition, the SBL program should be run under the Ballistic Missile Defense Organization Noun 1.

There is more to space than being an adjunct of the Air Force. James H. Hughes James Hurd Hughes (January 14 1867 – August 29 1953) was an American lawyer and politician from Dover, in Kent County, Delaware He was a member of the Democratic Party, who served as U.S. Senator from Delaware. ALBUQUERQUE, NM. Your excellent article on the space-based laser programs ("Killing Missiles from Space," June 2001, p. 16) demonstrates just how much progress has been made. Much of this progress is a result of achievements in the basic technologies of optics, beam control, sensing and targeting. As you point out in your sidebar story, development of the elements of a space-based laser system could contribute greatly to improving U.S. capabilities for space-based surveillance and imaging. These capabilities could be deployed even if the decision is eventually made nor to proceed with the space-based laser. These spin-off potentials are one of the reasons that investing in a space-based laser demonstration program makes sense. Dr. Daniel Goure ARLINGTON, VA. Clarification I would like to clarify some points in my article, "Pentagon Unfairly Criticized in Chem-Bio Defense Effort" (June 2001, p. 34). In the sixth paragraph, the sentence starting with "This group..." refers to the Senior Interagency Coordinating Group, not the Army's Soldier and BiologicalChemical Command. Booz-Allen and IEM IEM Industrial Engineering and Management (course/program) IEM In Ear Monitor IEM Institution of Engineers, Malaysia IEM Inborn Errors of Metabolism (molecular biology) IEM Intelligent Energy Management executed the CB HelpLine and CB Hotline tasks, respectively - two different initiatives. Last, NDPO NDPO National Domestic Preparedness Office replaced the HelpLine, not the hotline, with an email address. On a related note, I understand the NDPO is funding SBCCOM SBCCOM Soldier & Biological Chemical Command (US Army) to re-initiate the CB HelpLine, which can only benefit the emergency responders. I understand the need to ruthlessly edit articles to fit the magazine's parameters, but I was responsible for leading the development of the CB HelpLine and Hotline concepts, and I am concerned that those individuals out there will believe that I did not clearly understand the program. Al Mauroni ARLINGTON, VA. Churchill's Citizenship Regarding the article "USS USS abbr. 1. United States Senate 2. United States ship USS abbr (= United States Ship) → Namensteil von Schiffen der Kriegsmarine Churchill Shows Off High-Tech Gear" (April 2001, p. 28), I take issue with Mr. Kennedy's comment that, "... She is the first U.S. warship warship, any ship built or armed for naval combat. The forerunners of the modern warship were the men-of-war of the 18th and early 19th cent., such as the ship of the line, frigate, corvette, sloop of war (see sloop), brig, and cutter. to be named for an Englishman since the end of the American Revolution." While he was indeed an Englishman, because Mr Churchill's mother was a U.S. citizen, he also had U.S. citizenship. Don DiGenova GROTON, CONN. |
